I have been trying to add Button's below a GraphView, and all these elements are part of a Fragment. Tried many approaches but none of them worked properly.
This is the layout file for the Fragment (fragment_graph.xml).
<FrameLayout 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="com.nma.util.sdcardtrac.GraphFragment">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/graph_fragment_layout"
android:orientation="vertical"
/>
</FrameLayout>
And this is the Java code dynamically adding a graph and button, placed in the Fragment's onViewCreated (View view, Bundle savedInstanceState).
storageGraph = new LineGraphView(getActivity(), graphLabel);
storageGraph.addSeries(graphSeries); // More config calls follow
...
LinearLayout view = (LinearLayout)getView().findViewById(R.id.graph_fragment_layout);
Button button = new Button(getActivity());
button.setText("Test");
view.addView(storageGraph);
view.addView(button);
The Button is not visible though I have set orientation to vertical for the LinearLayout containing it.
EDIT - solved!
I found that nesting the graph under its own LinearLayout and the buttons under another LinearLayout, and both of these wrapped in a LinearLayout fixed the problem! The LinearLayout containing the graph must be weighted (I chose a weight of 0.8).
Layout file looks like:
<FrameLayout 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="com.nma.util.sdcardtrac.GraphFragment">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/graph_fragment_wrap"
android:orientation="vertical"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="0.8"
android:id="#+id/graph_fragment_layout"
android:orientation="vertical" />
<LinearLayout
android:id="#+id/graph_buttons"
android:orientation="horizontal"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_gravity="center_horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:src="#drawable/ic_navigation_previous_item"/>
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_navigation_next_item"/>
</LinearLayout>
</LinearLayout>
</FrameLayout>
I've just tried it and it works. Perhaps your graph is taking all the available space, so added button is below the screen? Try to wrap your LinearLayout into a ScrollView and see if there is a button in the bottom.

So I have an xml that consists of a linear layout containing a Button and a TextView like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="100dp"
android:orientation="vertical">
<Button
android:id="#+id/btnCell"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="start"
android:paddingLeft="40dp"
android:text="Button"
android:textColor="#color/blueText" />
<View
android:height="wrap_content"
android:width="wrap_content"
android:background="#drawable/Test"/>
</LinearLayout>
And I want to use this same layout inside other layouts in a different xml. I need the same button at every time, so I reuse it by including it in the two layouts (both layouts are in the same xml, but ones is hidden):
First one
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/image"
/>
<include layout="#layout/buttonLayout"/>
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
Second One:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:visibility="gone"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/image"
/>
<include layout="#layout/buttonLayout"/>
<CheckBox
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
So I show the first layout and hide the second one at the beginning of the app , as the user moves within the interface, the layouts exchange so that the other one is shown and the first one hidden.
The thing is that I declare the Button in my java activity class like this:
btnCell = (Button) thirdView.findViewById(R.id.btnCell);
btnCell.setOnClickListener(this);
And implemented the listener.
#Override
public void onClick(View v) {
if (v == btnCell) {
System.out.println("entered if");
}
System.out.println("entered function");
}
The problem is that when I click the button when the first view is shown and the second hidden, the button works just fine, but when I unhide the second layout, hide the first one, and proceed to click the button, that should be the same as the first one but in a different layout, nothing happens. I searched and find out, that this happens because the id is assigned only to the button shown in the first layout because of view hierarchy, but not the one in the second layout. How can I make both buttons react to the same action, without declaring a new button in each layout but instead reusing it?
I have used this type of layout. you can create Id different for both and inflate that view and give different name so You can differentiate both thing.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/image"
/>
<include android:id="+id/firstOne" layout="#layout/buttonLayout"/>
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
android second one is
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:visibility="gone"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/image"
/>
<include android:id="+id/secondTwo" layout="#layout/buttonLayout"/>
<CheckBox
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
The Problem is both the layout are include in same layout file and the id of that
button are same so whenever you click on any of the button at the same time event will fire on both button like both are clicked.
So, you have to give the different id for both the button I hope it works fine..
You can add a different Id for each included layout:
<include android:id="+id/layout_a" layout="#layout/buttonLayout"/>
and
<include android:id="+id/layout_b" layout="#layout/buttonLayout"/>
and then use two findViewById to reach them:
btnCellA = (Button)thirdView.findViewById(R.id.layout_a).findViewById(R.id.btnCell);
btnCellB = (Button)thirdView.findViewById(R.id.layout_b).findViewById(R.id.btnCell);
I have a ListView with 2 footer views. The first one is a bunch of TextViews, while the second one is a button. I'm trying to fix the second footer so that it always shows at the bottom of the screen.
I tried the following:
1. alignParentBottom = true
2. layout_gravity="bottom"
3. footerView2.bringToFront()
And combinations of the above. But none of them worked out. How can I achieve this?
UPDATE
I shouldn't have added the View which I always want on the screen (fixed) as footer.
I just added the wannabe-fixed-view with the listView. Did alignParentBottom = true and also view.bringToFront(). It worked out for me.
Separate your ListView and bottom footer. The idea is:
<?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">
<Button
android:id="#+id/btn_bottom"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="Bottom button"/>
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#id/btn_bottom"/>
</RelativeLayout>
Create separate xml file which contain all textviews and button you want as footer part.Then bind this xml as a footer of listview. You can binf footer with listview by this method: listview.addFooterView(footerView);
For example:
View footerView = ((LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE))
.inflate(R.layout.listviewfooter, null, false);
spDate = (Spinner) headerView.findViewById(R.id.spdate);
llDatepicker = (LinearLayout) headerView.findViewById(R.id.lldatepicker);
rvDatepicker = (RecyclerView) headerView.findViewById(R.id.rvdatepicker);
rvTimepicker = (RecyclerView) headerView.findViewById(R.id.rvtimepicker);
lvAddress.addFooterView(footerView);
If you are Trying to add a View which will be shown even if we scroll the List Up or Down... u can do something like this. I had done this before But as a header.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:id="#+id/new_container"
android:background="#color/white"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="LOAD EARLIER MESSAGES"
android:id="#+id/loadMore"
android:background="#90F58220"
android:visibility="visible"/>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/listContainer"
android:layout_below="#+id/loadMore"
android:layout_above="#+id/container">
<ListView
android:id="#+id/messagesContainer"
android:transcriptMode="normal"
android:dividerHeight="0dp"
android:divider="#null"
android:stackFromBottom="true"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
<RelativeLayout
android:id="#+id/container"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:background="#ffffff"
android:paddingTop="10dp"
android:paddingBottom="10dp"
android:paddingLeft="0dp"
android:paddingRight="0dp"
android:layout_height="wrap_content" >
</RelativeLayout>
The LoadMore Button is always visible on the Top of the List...
To add it to footer, Just Change
android:layout_below="#+id/loadMore"
android:layout_above="#+id/container"
to
android:layout_above="#+id/loadMore"
I'm running into some problems trying to figure out how to make fragments that I have programmatically added into a LinearLayout clickable. I'm using fragments because they will be in multiple activities and it was a good way for me to create a layout like this:
http://i.stack.imgur.com/P4lOG.png
But, if there's a better way to do this that would make the process of making it clickable, I'm certainly open to changing things up.
Anyway, I'm adding the fragments to the LinearLayout, jobsList, like so:
FragmentManager fragmentManager = getFragmentManager();
int count = 2;
for (int i = 0; i < count; i++) {
FragmentTransaction fragmentTransaction = fragmentManager
.beginTransaction();
Bundle bundle = new Bundle();
bundle.putInt("jobID", i + 1);
jobFragment job = new jobFragment();
job.setArguments(bundle);
fragmentTransaction.add(R.id.jobsList, job, Integer.toString(i));
fragmentTransaction.commit();
}
The count of 2 is just a placeholder for now, later there will be an arbitrary number of jobs.
Here is the layout, it's a bit of a mess but I got all the specific weights the way I wanted this way.

My question to you is, is it possible to make these fragments clickable and uniquely identifiable, and if so, what is the best way to go about doing that?
Thank you for your help!
What you could do is:
Modify the layout of your fragment, so it uses the RelativeLayout (now its probably LinearLayout right?). By modify I mean either use RelativeLayout INSTEAD of LinearLayout (more complicated but i think a bit better), or put your LinearLayout INSIDE RelativeLayout.
Place a view that matches in size the size of the fragment, on top of your textViews. Add an onClickListener to it that performes the code on clicks.
First - fragments are not clickable, layouts and their children are. A Fragment can handle the click action for things that occur in its layout but you do not "click" the fragment.
Second - sounds like you're confused about how to use fragments and what a Fragment actually does. A Fragment is like an Activity with some parts missing. A Fragment has its own lifecycle and can be used to perform many of the same tasks as an Activity the difference being that (1) a Fragment is "hosted" by an activity that provides the missing functions and does not run on its own (2) a Fragment can run in the background with no UI (I do not know of a background activity yet).
You do not need to/should not be using Fragments for what you are trying to do.
Your layout is really just a series of TextViews. You should be able to make that layout in XML reuse that layout file - by simply getting a LayoutInflater anywhere else in your app that you want to. If things got really crazy you could create a custom TextView class to provide detailed functionality but you should not be using 10 fragments, each with one TextView to make that layout work.
I just wanted to follow up on things in case anybody stumbles upon this answer in the future. It turns out using fragments was a bad idea. While I was able to make them clickable and identifiable through a bit of a hack job, I ran into problems later on when I was trying to fix layout issues. So, thanks to #Rarw I looked into using a LayoutInflater instead.
And that was much easier! I just made the layout xml file, used the LayoutInflater to add it to a LinearLayout and added that to the list. Makes things much easier down the road:
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
LinearLayout container = new LinearLayout(this);
inflater.inflate(R.layout.basic, container, true);
container.setId(i);
list.addView(container, params);
container.setClickable(true);
container.setOnClickListener(this);
A hacky solution is to place a transparent button on top of the entire fragment, have the fragment extend onClickListener, and set the button's onClickListener to this.
One way to create such a button:
Use a constraintLayout as the root layout for the xml.
As the last of child of the constraintLayout, create a button, constrain it to occupy entire fragment by setting layout_constrainXXX to corner elements.
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
<!-- The remaining properties of the layout -->
<!-- All the children of the layout -->
<Button
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
android:background="#00000000"
android:id="#+id/fragment_button" />
</android.support.constraint.ConstraintLayout>
Note that you can do this other ways too, such as in a RelativeLayout
Then in the java/kotlin file, extend onClickListener.
override fun onClick(p0: View?) {
// Whatever you want to do here
}
In method onActivityCreated, set the transparent button's listener as:
var button : Button = fragment_button
button.setOnClickListener(this)
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 an activity with the associated activity.xml code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/pattern_background"
android:orientation="vertical" >
<ScrollView
android:id="#+id/scrollView"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_marginBottom="5dp"
android:layout_weight="1"
android:clickable="false" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
...
<LinearLayout
android:id="#+id/llComments"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:orientation="vertical" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />
</LinearLayout>
</ScrollView>
<include
android:id="#+id/layoutComments"
android:layout_width="match_parent"
android:layout_height="wrap_content"
layout="#layout/widget_comentarios_fragment" >
</include>
In the LinearLayout with id llComments I introduce a fragment called CommentsFragment dynamically from the activity with the following code:
private Fragment commentsFragment;
private FragmentTransaction ft;
...
llComentarios = (LinearLayout) findViewById(R.id.llComments);
...
Bundle args = new Bundle();
args.putString(Constants.IDMODEL, getId());
commentsFragment = CommentsFragment.newInstance(args);
ft = getSupportFragmentManager().beginTransaction();
ft.add(R.id.llComments, commentsFragment).commit();
The Fragment associated xml file is:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:paddingRight="#dimen/indicator_internal_padding" />
</LinearLayout>
The problem I cannot solve is to show in the activity more than one item (in fact I am showing one and a third items) in the list if I do not fix a height for the listview.It should adapt to as many items I add to the list in the fragment through the adapter. I have tried different combinations of heights in the layouts and views, but still does not work. Maybe I am annulating one with other.
Any help would be appreciated.
Thanks in advance
After some days I find out the exact problem. I was including a ListView into a ScrollView, and that's clearly not recomended by Android developers.
You can look for further info here: Why ListView cannot be used in a ScrollView?
Anyway, if you want to do it, you can do that with a hack. Take a look at these proposals:
How can I put a ListView into a ScrollView without it collapsing?
For me that worked. Problem solved.
