I have a xml with one NavigationView and two different RelativeLayouts.
One of the RelativeLayouts is hidden at first (I change its visibility in the onCreate() to GONE).
When I click on a button inside the NavigationView I want the hidden layout to become visible.
This is my Java code:
RelativeLayout imagenes,registro;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_invitado);
registro = (RelativeLayout) findViewById(R.id.registro);
imagenes = (RelativeLayout) findViewById(R.id.imagenes);
registro.setVisibility(View.INVISIBLE);
imagenes.setVisibility(View.VISIBLE);
mDrawerlayout= (DrawerLayout) findViewById(R.id.drawer_layout);
mToggle= new ActionBarDrawerToggle(this,mDrawerlayout,R.string.open,R.string.close);
mDrawerlayout.addDrawerListener(mToggle);
mToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
public void registrarse(View v){
mDrawerlayout.closeDrawers();
registro.setVisibility(View.VISIBLE);
}
And here the xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

I could fix your code.
1 - Fix your DrawerLayout
DrawerLayout layout file must have an specific format:
<DrawerLayout>
<Content Layout /> <!-- It can be linearlayout, framelayout etc -->
<NavigationView />
</DrawerLayout>
You have 2 RelativeLayouts and one NavigationView. You have more items than allowed and in wrong order. So, for tests, I moved both imagenes and registro into a LinearLayout` (you could improve and keep all items inside only one relative layout.. but lets leave that for another time).
I did not change anything... I just move NavigationView to the bottom of the file and move both RelativeLayout into a LinearLayout
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<RelativeLayout
android:id="#+id/imagenes"
... >
....
</RelativeLayout>
<RelativeLayout
...>
.....
</RelativeLayout>
</LinearLayout>
<android.support.design.widget.NavigationView
.... />
</android.support.v4.widget.DrawerLayout>
2 - Fix your code
Since both RelativeLayout were placed in a LinearLayout and it is vertical aligned, View.INVISBLE does not work anynore for us. So, you should use View.Gone and change your code as follows:
#Override
protected void onCreate(Bundle savedInstanceState) {
....
imagenes.setVisibility(View.VISIBLE);
registro.setVisibility(View.GONE);
....
}
public void registrarse(View v){
mDrawerlayout.closeDrawers();
imagenes.setVisibility(View.GONE);
registro.setVisibility(View.VISIBLE);
}
3 - Another possibilites
Since your DrawerLayout was not properly configured, I wonder if your navigations items were being called. So, maybe, your code is not even calling registrarse(View v).. However, but that is hard to cofirm with current code attached.
For any case, with the modifications I mentioned above and if your code is calling registrarse properly, it should work normally.
You are not seeing the RelativeLayout after changing it's visibility to View.VISIBLE because you have set the height and width of both RelativeLayout to match_parent , so the imagenes occupies whole screen and it is on top of registro.
Try putting them inside a ScrollView or adjust their heights or call registro.bringToFront() after making it visible.
height and width of imagenes RelativeLayout is match parent so it takes whole screen..u need to set appropriate height to see registro RelativeLayout or put it in ScrollView

I created a menuView.xml layout to be in all of the layouts of my activity. This layout has one column on each border and a title bar like this:
ComposeView http://img845.imageshack.us/img845/2121/d6zp.png
I insert this layout in the other layouts this way:
<!-- Show menu -->
<com.example.MenuView
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
But if one of the layouts has full screen view, part of this view gets covered by the MenuView, so...
How could I tell to this view to adapt its size to the blank space inside the MenuView to not get covered by it?
UPDATE -- full XML included
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:background="#drawable/degradado">
<!-- Show menu -->
<com.example.MenuView
android:layout_width="match_parent"
android:layout_height="match_parent" />
<RelativeLayout
android:id="#+id/Left_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentBottom="true" >
//Here go buttons, views, etc...
</RelativeLayout>
<RelativeLayout
android:id="#+id/Right_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true" >
//Here go buttons, views, etc...
</RelativeLayout>
What happens here is that these 2 Relative layouts get covered by the MenuView (The darkest gre borders and the top black bar), and the ideal way would be that these 2 layouts get fitted to the blank space (the clearest gray).
I can solve this setting margin sizes to the Relative layouts to fit inside of it, but i know this is not the best way to do it, so I don't know if there is another way.
I think the best way to solve your issue is with inheritance.
If you define an Activity that can be used as a template for all your fleshed out Activitys to add their content to.
I don't know what you custom menu is 'made of' but as a simple example:
Create a basic Activity with code:
public class ActivityWithMenu extends Activity
{
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_with_menu_layout);
}
}
and xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".ActivityWithMenu" >
<TextView
android:layout_width="match_parent"
android:layout_height="20dip"
android:background="#ff000000"
android:textColor="#ffffffff"
android:text="Main Menu Title Bar"
android:id="#+id/mainmenutitle" />
<LinearLayout
android:layout_width="20dip"
android:layout_height="match_parent"
android:layout_below="#+id/mainmenutitle"
android:layout_alignParentLeft="true"
android:background="#ff999999"
android:orientation="vertical"
android:id="#+id/lefthandmenu" />
<LinearLayout
android:layout_width="20dip"
android:layout_height="match_parent"
android:layout_below="#+id/mainmenutitle"
android:layout_alignParentRight="true"
android:background="#ff999999"
android:orientation="vertical"
android:id="#+id/righthandmenu" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_toLeftOf="#+id/righthandmenu"
android:layout_toRightOf="#+id/lefthandmenu"
android:layout_below="#+id/mainmenutitle"
android:orientation="vertical"
android:id="#+id/activitycontent"
/>
</RelativeLayout>
Then create your xml for a specific Activity, in this case a simple 'Hello World' layout:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ff00ff00"
android:text="Hello World!"
/>
</LinearLayout>
</ScrollView>
But now when you write the code for this Activity, extend 'ActivityWithMenu' instead of the Activity class direct and inflate this xml layout as follows:
public class Activity1 extends ActivityWithMenu
{
#Override
protected void onCreate(Bundle savedInstanceState)
{
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
super.onCreate(savedInstanceState);
LinearLayout ll = (LinearLayout)findViewById(R.id.activitycontent);
ScrollView sv = (ScrollView)this.getLayoutInflater().inflate(R.layout.activity1_layout, ll, false);
ll.addView(sv);
}
}
I have added the code for making the Activity fullscreen here instead of in the parent ActivityWithMenu class assuming that you wouldn't want them all displayed that way but you could move it into the parent class if appropriate.
Hope this helps.
I have a list that is intended to be below toggle buttons. The list grabs data from a server and then parses them. My XML is as follows:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<ToggleButton
android:id="#+id/toggle_button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textOff="Apps"
android:textOn="Apps" />
<ToggleButton
android:id="#+id/toggle_button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/toggle_button1"
android:layout_weight="1"
android:textOff="VMs"
android:textOn="VMs" />
<ToggleButton
android:id="#+id/toggle_button3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/toggle_button2"
android:layout_weight="1"
android:textOff="Groups"
android:textOn="Groups" />
<ListView
android:id="#+id/mylist"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/toggle_button1" />
</RelativeLayout>
Code for the actual fragment:
public class ProblemFragment extends SherlockListFragment
{
private SeparatedListAdapter list;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
this.getSherlockActivity().setContentView(R.layout.problem_layout);
list = new SeparatedListAdapter(this.getSherlockActivity(), new Layout(R.layout.separated_list_adapter_two_text, R.id.two_text_title, R.id.two_text_desc));
ToggleButton b1 = (ToggleButton) this.getSherlockActivity().findViewById(R.id.toggle_button1);
ToggleButton b2 = (ToggleButton) this.getSherlockActivity().findViewById(R.id.toggle_button2);
ToggleButton b3 = (ToggleButton) this.getSherlockActivity().findViewById(R.id.toggle_button3);
setListAdapter(list);
refresh();
}
public void refresh()
{
list = new SeparatedListAdapter(this.getSherlockActivity(), new Layout(R.layout.separated_list_adapter_two_text, R.id.two_text_title, R.id.two_text_desc));
refreshStats();
}
public void refreshStats()
{
//Omitted parsing code
list.addSection(new String("Hello world!!"));
setListAdapter(list);
}
}
However, when I use setListAdapter(list), the buttons are overwritten. They are visible before the app retrieves the data and parses it, but they are overwritten after I call setListAdapter. How can i fix this?
First, remove
android:orientation="horizontal"
from your root layout. RelativeLayout doesn't have an orientation property. Also, weight is for child elements of a LinearLayout and when you use it then you should assign the width of each child view to 0dp for horizontal orientation and height="0dp" for vertical orientation.
Then wrap your ToggleButtons in a LinearLayout, vertical or horizontal orientation, and give it the property
android:layout_alignParentTop="true"
then give your ListView the property
android:layout_below="#id/idOfLinearLayout"
So it may look something like
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:id="#+id/toggleLL"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true">
<ToggleButton
android:id="#+id/toggle_button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textOff="Apps"
android:textOn="Apps" />
<ToggleButton
android:id="#+id/toggle_button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textOff="VMs"
android:textOn="VMs" />
<ToggleButton
android:id="#+id/toggle_button3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textOff="Groups"
android:textOn="Groups" />
</LinearLayout>
<ListView
android:id="#+id/mylist"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/toggleLL" />
</RelativeLayout>
I also removed the RelativeLayout properties from the ToggleButtons since they are now wrapped in a LinearLayout. And you had a circular view error there with assigning the second ToggleButton to the right of itself which may have been a copy/paste error. Hope this helps.
Note that the default orientation for a LinearLayout is horizontal so leaving that property out will give you that effect.
Oh! I can not test your XML but I think that you need scrollbars! If the list is filled with a lot of entries, it can became bigger that the screen, making the buttons disappear because they are pushed up by the list. Try to add a scroll to the whole layout.
Something like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<ScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<!-- Original layout here -->
</ScrollView>
</LinearLayout>
Of course, if you just put only one layout inside the scrollview, there is no need for the outer layout:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Original layout here -->
</ScrollView>
In my app I have a sliding drawer with image buttons in them and when clicked it displays the image description and info. So basically I am only using one XML file and one Java file for this. (But I have noticed that adding more imagebuttons and mages to display it takes a while to load). And now that since API 17 is deprecating the sliding drawer leaves me a bit worried for future downloads of the app. Now my question is, is there a alternative way to achieve this without using sliding drawer or spinner. I don't really want to create a xml and java file for each image (I'll end up with 100+ xml's and java's)
Here is my code that I have at the moment.
XML:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/iM1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="fitStart"
android:adjustViewBounds="true"/>
</RelativeLayout>
</ScrollView>
<SlidingDrawer
android:id="#+id/sD1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:content="#+id/content"
android:handle="#+id/handle">
<Button
android:id="#+id/handle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/icon_1" />
<RelativeLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/icon_background1">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<Button
android:id="#+id/asample"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/imageicon1"/>
.....
And Java:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.campsites);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
final SlidingDrawer slider = (SlidingDrawer) findViewById(R.id.sD1);
final ImageView imageView = (ImageView) findViewById(R.id.iM1);
slider.animateOpen();
Button next = (Button) findViewById(R.id.asample);
Button next1 = (Button) findViewById(R.id.bsample);
..........
next.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
imageView.setImageDrawable(getResources().getDrawable(R.drawable.asample));
slider.animateClose();
}
});
next1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
imageView.setImageDrawable(getResources().getDrawable(R.drawable.bsample));
slider.animateClose();
}
});
............
Can anyone please help or have a suggestion on what to do?
This is a SlidingDrawer from the left, correct? If so, you can look into DrawerLayout.
This is part of the Android Support Library and you should be able to replace your XML with this instead fairly simply and be backwards compatible to API4
From that page, there is an example.
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- The navigation drawer -->
<ListView android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#111"/>
</android.support.v4.widget.DrawerLayout>
Some notes from that page
This layout demonstrates some important layout characteristics:
The main content view (the FrameLayout above) must be the first child in the DrawerLayout because the XML order implies z-ordering and
the drawer must be on top of the content. The main content view is set
to match the parent view's width and height, because it represents the
entire UI when the navigation drawer is hidden.
The drawer view (the ListView) must specify its horizontal gravity with the android:layout_gravity attribute. To support right-to-left
(RTL) languages, specify the value with "start" instead of "left" (so
the drawer appears on the right when the layout is RTL).
The drawer view specifies its width in dp units and the height matches the parent view. The drawer width should be no more than 320dp
so the user can always see a portion of the main content.
Mostly the difference is that the DrawerLayout is top level and you put your XML within it. So something like this (totally untested):
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- your content surrounded by a layout to signify that it's actually content -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/iM1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="fitStart"
android:adjustViewBounds="true"/>
</RelativeLayout>
</ScrollView>
</RelativeLayout>
<!-- your sliding menu in its own layout -->
<LinearLayout
android:layout_gravity="start"
android:layout_width="240dp"
android:layout_height="wrap_content">
<Button
android:id="#+id/handle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/icon_1" />
<RelativeLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/icon_background1">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<Button
android:id="#+id/asample"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/imageicon1"/>
.....
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
i thinks This is a good alternative
AFAIK it does not use SlidingDrawer and you can modify the direction of the drawer
The SlidingUpPanel from the guys of the app Umano seems the best way right now. You can find it in: https://github.com/umano/AndroidSlidingUpPanel
I found the information about it in this other SOF post: vertical DrawerLayout or SlidingPaneLayout
:D
Edit: This one also looks very promising: https://github.com/6wunderkinder/android-sliding-layer-lib
(in the youtube video seems to work just from right to left and left to right, but if you download the actual demo app, you will see that it´s also possible to go from bottom to top and top to bottom)
I would rather suggest a simple sliding menu, that i created myself.
concept i used
Slider button and content panel
initially slider button is to the left(in my example) , when you click on it ,it shifts and the content pane is made visible
how i achieived this
I played with the margin left , so when you press the slider button the content pane (hidden initially) becomes as wide as screen_width/3 , and when you press it again it hides..
heres my code to it.
public class MainActivity extends Activity {
boolean toggle_open=false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
public void open(View v){
switch (v.getId()) {
case R.id.imageButton1:
if(!toggle_open){
RelativeLayout header=(RelativeLayout)findViewById(R.id.header);
Display size=getWindow().getWindowManager().getDefaultDisplay();
int widthby2=size.getWidth()/3;
RelativeLayout.LayoutParams lp=new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT);
lp.setMargins(size.getWidth()/2, 0, 0, 0);
header.setLayoutParams(lp);
RelativeLayout slider=(RelativeLayout)findViewById(R.id.panel);
slider.setLayoutParams(new RelativeLayout.LayoutParams((size.getWidth()/2),size.getHeight()));
slider.setVisibility(View.VISIBLE);
toggle_open=true;
}
else{
RelativeLayout header=(RelativeLayout)findViewById(R.id.header);
RelativeLayout.LayoutParams lp=new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT);
lp.setMargins(0, 0, 0, 0);
header.setLayoutParams(lp);
RelativeLayout slider=(RelativeLayout)findViewById(R.id.panel);
slider.setVisibility(View.GONE);
toggle_open=false;
}
break;
default:
break;
}
}
}

plain android you can use DrawerLayout.
but i recommend SlidingMenu lib what has a better usability for user and programmer.
Most of the answers are pretty old. If you are working on API 30/31 you should use a Sheet instead. As described on the Android Material design documentation
Layout:
<androidx.coordinatorlayout.widget.CoordinatorLayout
...>
<FrameLayout
...

Two things to pay attention to are:
Notice both the app:layout_behavior and style of the FrameLayout
In order for the Sheet to work it needs to be enclosed in a CoordinatorLayout
Sample Fragment:
class ModalBottomSheet : BottomSheetDialogFragment() {
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? = inflater.inflate(R.layout.modal_bottom_sheet_content, container, false)
companion object {
const val TAG = "ModalBottomSheet"
}
}
Activity Code:
You can show the Sheet programmatically by using this...
val modalBottomSheet = ModalBottomSheet()
modalBottomSheet.show(supportFragmentManager, ModalBottomSheet.TAG)
In my app I have a sliding drawer with image buttons in them and when clicked it displays the image description and info. So basically I am only using one XML file and one Java file for this. (But I have noticed that adding more imagebuttons and mages to display it takes a while to load). And now that since API 17 is deprecating the sliding drawer leaves me a bit worried for future downloads of the app. Now my question is, is there a alternative way to achieve this without using sliding drawer or spinner. I don't really want to create a xml and java file for each image (I'll end up with 100+ xml's and java's)
Here is my code that I have at the moment.
XML:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/iM1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="fitStart"
android:adjustViewBounds="true"/>
</RelativeLayout>
</ScrollView>
<SlidingDrawer
android:id="#+id/sD1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:content="#+id/content"
android:handle="#+id/handle">
<Button
android:id="#+id/handle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/icon_1" />
<RelativeLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/icon_background1">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<Button
android:id="#+id/asample"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/imageicon1"/>
.....
And Java:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.campsites);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
final SlidingDrawer slider = (SlidingDrawer) findViewById(R.id.sD1);
final ImageView imageView = (ImageView) findViewById(R.id.iM1);
slider.animateOpen();
Button next = (Button) findViewById(R.id.asample);
Button next1 = (Button) findViewById(R.id.bsample);
..........
next.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
imageView.setImageDrawable(getResources().getDrawable(R.drawable.asample));
slider.animateClose();
}
});
next1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
imageView.setImageDrawable(getResources().getDrawable(R.drawable.bsample));
slider.animateClose();
}
});
............
Can anyone please help or have a suggestion on what to do?
This is a SlidingDrawer from the left, correct? If so, you can look into DrawerLayout.
This is part of the Android Support Library and you should be able to replace your XML with this instead fairly simply and be backwards compatible to API4
From that page, there is an example.
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- The navigation drawer -->
<ListView android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#111"/>
</android.support.v4.widget.DrawerLayout>
Some notes from that page
This layout demonstrates some important layout characteristics:
The main content view (the FrameLayout above) must be the first child in the DrawerLayout because the XML order implies z-ordering and
the drawer must be on top of the content. The main content view is set
to match the parent view's width and height, because it represents the
entire UI when the navigation drawer is hidden.
The drawer view (the ListView) must specify its horizontal gravity with the android:layout_gravity attribute. To support right-to-left
(RTL) languages, specify the value with "start" instead of "left" (so
the drawer appears on the right when the layout is RTL).
The drawer view specifies its width in dp units and the height matches the parent view. The drawer width should be no more than 320dp
so the user can always see a portion of the main content.
Mostly the difference is that the DrawerLayout is top level and you put your XML within it. So something like this (totally untested):
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- your content surrounded by a layout to signify that it's actually content -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/iM1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="fitStart"
android:adjustViewBounds="true"/>
</RelativeLayout>
</ScrollView>
</RelativeLayout>
<!-- your sliding menu in its own layout -->
<LinearLayout
android:layout_gravity="start"
android:layout_width="240dp"
android:layout_height="wrap_content">
<Button
android:id="#+id/handle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/icon_1" />
<RelativeLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/icon_background1">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<Button
android:id="#+id/asample"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/imageicon1"/>
.....
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
i thinks This is a good alternative
AFAIK it does not use SlidingDrawer and you can modify the direction of the drawer
The SlidingUpPanel from the guys of the app Umano seems the best way right now. You can find it in: https://github.com/umano/AndroidSlidingUpPanel
I found the information about it in this other SOF post: vertical DrawerLayout or SlidingPaneLayout
:D
Edit: This one also looks very promising: https://github.com/6wunderkinder/android-sliding-layer-lib
(in the youtube video seems to work just from right to left and left to right, but if you download the actual demo app, you will see that it´s also possible to go from bottom to top and top to bottom)
I would rather suggest a simple sliding menu, that i created myself.
concept i used
Slider button and content panel
initially slider button is to the left(in my example) , when you click on it ,it shifts and the content pane is made visible
how i achieived this
I played with the margin left , so when you press the slider button the content pane (hidden initially) becomes as wide as screen_width/3 , and when you press it again it hides..
heres my code to it.
public class MainActivity extends Activity {
boolean toggle_open=false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
public void open(View v){
switch (v.getId()) {
case R.id.imageButton1:
if(!toggle_open){
RelativeLayout header=(RelativeLayout)findViewById(R.id.header);
Display size=getWindow().getWindowManager().getDefaultDisplay();
int widthby2=size.getWidth()/3;
RelativeLayout.LayoutParams lp=new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT);
lp.setMargins(size.getWidth()/2, 0, 0, 0);
header.setLayoutParams(lp);
RelativeLayout slider=(RelativeLayout)findViewById(R.id.panel);
slider.setLayoutParams(new RelativeLayout.LayoutParams((size.getWidth()/2),size.getHeight()));
slider.setVisibility(View.VISIBLE);
toggle_open=true;
}
else{
RelativeLayout header=(RelativeLayout)findViewById(R.id.header);
RelativeLayout.LayoutParams lp=new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT);
lp.setMargins(0, 0, 0, 0);
header.setLayoutParams(lp);
RelativeLayout slider=(RelativeLayout)findViewById(R.id.panel);
slider.setVisibility(View.GONE);
toggle_open=false;
}
break;
default:
break;
}
}
}

plain android you can use DrawerLayout.
but i recommend SlidingMenu lib what has a better usability for user and programmer.
Most of the answers are pretty old. If you are working on API 30/31 you should use a Sheet instead. As described on the Android Material design documentation
Layout:
<androidx.coordinatorlayout.widget.CoordinatorLayout
...>
<FrameLayout
...
android:id="#+id/standard_bottom_sheet"
style="?attr/bottomSheetStyle"
app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior">
<!-- Contents -->
<ImageButton
android:id="#+id/imageButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:background="#android:color/black"
android:onClick="open"
android:src="#android:drawable/ic_dialog_dialer" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/imageButton1"
android:layout_toRightOf="#+id/imageButton1"
android:text="Admin Panel"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="#android:color/white" />
<!-- Contents End -->
</FrameLayout>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
Two things to pay attention to are:
Notice both the app:layout_behavior and style of the FrameLayout
In order for the Sheet to work it needs to be enclosed in a CoordinatorLayout
Sample Fragment:
class ModalBottomSheet : BottomSheetDialogFragment() {
override fun onCreateView(

): View? = inflater.inflate(R.layout.modal_bottom_sheet_content, container, false)
companion object {
const val TAG = "ModalBottomSheet"
}
}

You can show the Sheet programmatically by using this...
val modalBottomSheet = ModalBottomSheet()
modalBottomSheet.show(supportFragmentManager, ModalBottomSheet.TAG)
I have multiple activities in my app and i want a slidingdrawer to appear in all the activities. I am following the approach given here.
The app starts with a black screen with the slidingdrawer handle.
Issue is that the sliding drawer is visible but the activity layout put in FarmeLayout is not visible.
The activity is there for sure. Toasts came up when the first activity loaded. So I modified my first activity to have only a button on it to go to next activity.
Next I used the direction keys on the AVD, and pressed ok which brought up the the next activity's Toast. Second activity is as well hidden.
So what am I missing???
My Sliding Drawer layout xml (LinearLayout) with farme layout at the end:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:gravity="center_vertical">
<SlidingDrawer

android:handle="#+id/drawerHandle"
android:content="#+id/contentLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:persistentDrawingCache="all">
<ToggleButton
android:id="#+id/drawerHandle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:maxHeight="5dp"
android:textSize="14dp"
android:textStyle="italic"
android:background="#BB00FF"
android:rotation="270"
android:textOn=""
android:textOff=""/>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/contentLayout"
android:gravity="center"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:contentDescription="#string/todo">
<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:text="#string/list_view_" />
</LinearLayout>
</SlidingDrawer>
<FrameLayout
android:id="#+id/act_content"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="#808080"
android:visibility="visible">
</FrameLayout>
</LinearLayout>
DrawerActivity java code:
public abstract class DrawerActivity extends Activity
{
protected LinearLayout fullLayout;
protected FrameLayout actContent;
#Override
public void setContentView(final int layoutResID)
{
fullLayout= (LinearLayout) getLayoutInflater().inflate(R.layout.act_layout, null); // Your base layout here
actContent= (FrameLayout) fullLayout.findViewById(R.id.act_content);
getLayoutInflater().inflate(layoutResID, actContent, true); // Setting the content of layout your provided to the act_content frame
super.setContentView(fullLayout);
}
}
In all my activitie files I have put setContentView(R.layout.XXXXXXXX); in the onCreate method.
So how do I make the activities visible?? What am I doing wrong??
I tried putting in the following but to no effect
actContent.setVisibility(layoutResID);
or
actContent.setVisibility(View.VISIBLE);
