How to use AppCompatActivity with Fabric to get Timeline? - android

I am following fabric's documentation to get a timeline. It works fine if I use ListActivity according to their instruction. But I want to add my own toolbar so I used AppCompatActivity instead. Here is part of my java file:
public class TimelineActivity extends AppCompatActivity{
public static final String QUERY = "QUERY";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_timeline);
Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
SearchTimeline searchTimeline = new SearchTimeline.Builder()
.query(getIntent().getStringExtra(QUERY))
.build();
final TweetTimelineListAdapter adapter = new TweetTimelineListAdapter.Builder(this)
.setTimeline(searchTimeline)
.build();
ListView tweetList = (ListView)findViewById(R.id.tweet_list);
tweetList.setAdapter(adapter);
}
And here is my xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".TimeLineActivity">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_scrollFlags="scroll|enterAlways"/>
</android.support.design.widget.AppBarLayout>
<LinearLayout
android:layout_below="#id/appbar"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<TextView android:id="#id/android:empty"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal|center_vertical"
android:text="Please wait . . ."/>
<ListView android:id="#+id/tweet_list"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:divider="#e1e8ed"
android:dividerHeight="1dp"
android:drawSelectorOnTop="false"/>
</LinearLayout>
</RelativeLayout>
Problem is, it doesn't show any result. I am stuck with the "Please wait . . ." TextView.

Answered it myself, since I didn't extend ListActivity, I need to add the TextView with Id = empty, manually using setEmptyView().
TextView emptyText = (TextView)findViewById(android.R.id.empty);
ListView tweetList = (ListView)findViewById(R.id.tweet_list);
tweetList.setEmptyView(emptyText);
tweetList.setAdapter(adapter);

Android listview doesn't get displayed in bottomsheet

I want to create a navigational bottom sheet like that in Google Maps Navigational BottomSheet where we have the list of directions for the route. I am using android's BottomSheetBehaviour to open up the bottomsheet. The issue i am currently facing is that the listview doesn't show up inside the bottom sheet layout when it pops up. The view is simply blank. I also tried to inflate view myself inside a NestedScrollView to get the same result, but that too didn't show up.
This is my bottomsheet xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/bottomSheet1"
android:orientation="vertical"
android:paddingLeft="20dp"
android:paddingRight="20dp"
android:elevation="4dp"
android:background="#color/white"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior"
android:clipToPadding="true"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:text="This is a sheet with listview."
android:textSize="20dp"
android:layout_marginTop="10dp"
android:textColor="#color/primaryText"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<TextView
android:text="This is a secondary text!"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<android.support.v4.widget.NestedScrollView
android:visibility="gone"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/nestedLinearLayout"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
<ListView
android:id="#+id/bottomSheetListview"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
And in my java code,
View bottomSheetView = findViewById(R.id.bottomSheet1);
ListView listView = (ListView) findViewById(R.id.bottomSheetListview);
List<String> listData = getListData(); //returns a simple array list of strings, about 15 items
listView.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,listData));
mBottomSheetBehavior = BottomSheetBehavior.from(bottomSheetView);
mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED);
Am I doing anything wrong here? Why doesn't the litview or scrollview show up.
Edited

I imported your xml and the android studios "Preview" indeed showed that the NestedScrollView with android:layout_height="match_parent" takes the whole space so the ListView hasn't got space left.
When setting the NestedScrollView to android:visibility="gone" the ListView has enough space.
So the only reason now that nothing is shown is maybe because your listData is empty?
EDIT
OK I implemented all info and the style is very messy. First of all the peek 1 button is behind the toolbar.
But I can still click it, so this happens:
Dont make your listview visibility gone at first. Bottom should know what size it has to be. If you need to make its visibility gone, done it after the bottom sheet created.
And try in your bottom sheet content_bottom_shee.xml parent linearlayout
android:fillViewport="true"

How to set a toolbar in a List Activity?

I want to change the app I have created so far, in order to implement a ListView. I followed this example and this example. The examples alone work, but not together with the changes I had to make to my so-far existing app.
I have a avticity_main.xml defined as follows:
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context=".MainActivity" >
<android.support.design.widget.AppBarLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"/>
</android.support.design.widget.AppBarLayout>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/main_grid"
android:useDefaultMargins="true"
android:alignmentMode="alignBounds"
android:columnOrderPreserved="false"
android:columnCount="4"
>
<TextView
android:text="MainTitle"
android:textSize="32dip"
android:layout_columnSpan="4"
android:layout_gravity="center_horizontal"
android:id="#+id/textView1"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<ListView
android:id="#+id/list"
android:layout_height="wrap_content"
android:layout_width="match_parent">
</ListView>
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
and I have the following code for my main activity:
public class MainActivity extends AppCompatActivity {
static final String[] MOBILE_OS =
new String[] { "Android", "iOS", "WindowsMobile", "Blackberry"};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
ListView list = (ListView) findViewById(R.id.list);
list.setAdapter(new ListAdapter(this, MOBILE_OS));
The code compiles fine, but no list is shown.
ListActivity is a "convenience" class to implement a simple ListView. And that's pretty much all you can do. So, there's no setSupportActionBar(Toolbar) there.
To achieve what you want, use AppCompatActivity or default Activity.
This link provides a nice tutorial on how to use the new ToolBar instead of the old ActionBar.
You want something like this:
This layout example could be used:
P.S.: "#color/primary" could be any color like #FF009688.
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent" android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:id="#+id/toolbar"
android:background="#color/primary"
android:elevation="4dp">
</android.support.v7.widget.Toolbar>
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/toolbar"
android:id="#+id/lv"></ListView>
</RelativeLayout>
And on the Java side:
YourActivity.java
public class MainActivity extends AppCompatActivity {
private Toolbar toolbar;
private ListView lv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
lv = (ListView) findViewById(R.id.lv);
setSupportActionBar(toolbar);
final ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setHomeAsUpIndicator(R.drawable.ic_menu_white_24dp);
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayHomeAsUpEnabled(true);
}
// Populate the ListView here...
}
}
EDIT: This other answer of mine can show you how to create a Custom Adapter to display the data you want on the ListView.
Second edit: Use this layout
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"

android:layout_height="wrap_content"
android:layout_width="match_parent"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"/>

<LinearLayout

app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/main_grid"
android:useDefaultMargins="true"
android:alignmentMode="alignBounds"
android:columnOrderPreserved="false"
android:columnCount="4"
android:orientation="vertical">
<TextView
android:text="MainTitle"
android:textSize="32dip"
android:layout_columnSpan="4"
android:layout_gravity="center_horizontal"
android:id="#+id/textView1"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<ListView
android:id="#+id/list"
android:layout_height="wrap_content"
android:layout_width="match_parent">
</ListView>
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
What did I do?
Your LinearLayout was lacking the orientation parameter on the XML, and your TextView had a android:layout_height set to match_parent, so it was filling the entire layout. I've changed it to wrap_content and you're good to go.
setSupportActionBar(toolbar) is not available in ListActivity. You can use AppCompatActivity instead and just get a reference to the listview:
ListView list = findViewById(R.id.list); and use list.setAdapter(adapter) instead of setListAdapter(adapter);
You can't do that in ListActivity.
If you want to access getSupportActionBar(), you need to extent your class by AppCompatActivity.
My Suggestion : Don`t use ListActivty is you want to use ToolBar. Create an Activity and then only have ListView within that Activity. It'll work just fine.
OR
Toolbar toolbar = (Toolbar) findViewById(R.id.my_awesome_toolbar);
// Set an OnMenuItemClickListener to handle menu item clicks
toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
// Handle the menu item
return true;
}
});
// Inflate a menu to be displayed in the toolbar
toolbar.inflateMenu(R.menu.your_toolbar_menu);
}`
You can use the new AppCompatDelegate component provided by the Support Library to easily add a Toolbar to your ListActivity.

How to add image in toolbar

I am following this example to create my app now i am trying to add image in my toolbar the but image is not displaying,i am trying to set my app logo,following is my code and toolbar xml can any one tell me what is mistake?
toolbar.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
local:theme="#style/MyMaterialTheme.Base"
local:popupTheme="#style/ThemeOverlay.AppCompat.Light" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/toolbartitle"
/>
</android.support.v7.widget.Toolbar>
MainActivity.java
public class MainActivity extends AppCompatActivity implements FragmentDrawer.FragmentDrawerListener {
private static String TAG = MainActivity.class.getSimpleName();
private Toolbar mToolbar;
private FragmentDrawer drawerFragment;
private String chng;
private Intent i;
public SearchView searchView;
public SearchManager searchManager;
// Alert Dialog Manager
AlertDialogManager alert = new AlertDialogManager();
// Session Manager Class
SessionManager session;
private String id;
private boolean b;
private String rasa;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
session = new SessionManager(getApplicationContext());
id = getIntent().getStringExtra("id");
System.out.println("MAIN ID : " + id);
/* i=getIntent();
chng=i.getStringExtra("Changes");*/
// Toast.makeText(getApplicationContext(),chng,Toast.LENGTH_LONG).show();
mToolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(mToolbar);
getSupportActionBar().setDisplayShowHomeEnabled(false);
getSupportActionBar().setDisplayShowTitleEnabled(false);
drawerFragment = (FragmentDrawer)
getSupportFragmentManager().findFragmentById(R.id.fragment_navigation_drawer);
drawerFragment.setUp(R.id.fragment_navigation_drawer, (DrawerLayout) findViewById(R.id.drawerLayout),mToolbar);
drawerFragment.setDrawerListener(this);
displayView(0);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
This how my toolbar shows right now
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/color_blue"
app:popupTheme="#style/AppTheme.PopupOverlay">
<ImageView
android:id="#+id/tv_header_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:src="#mipmap/header_title" />
</android.support.v7.widget.Toolbar>
You can set Event of button also by this method...
public static void showToolBar(Toolbar toolbar,
final AppCompatActivity activity) {
activity.setSupportActionBar(toolbar);
activity.getSupportActionBar().setDisplayShowTitleEnabled(false);
#SuppressWarnings("deprecation")
Drawable drawable = activity.getResources().getDrawable(
R.mipmap.back_icon);
drawable.setColorFilter(
activity.getResources().getColor(R.color.color_white),
android.graphics.PorterDuff.Mode.SRC_ATOP);
activity.getSupportActionBar().setHomeAsUpIndicator(drawable);
toolbar.setBackgroundColor(activity.getResources().getColor(
R.color.color_blue));
activity.getSupportActionBar().setDisplayHomeAsUpEnabled(true);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
activity.finish();
}
});
}
Use the logo display on the action bar.
getSupportActionBar().setLogo(R.drawable.logo);
getSupportActionBar().setDisplayUseLogoEnabled(true);
instead you can set your image as textview background. use android:background="#drawable/toolbartitle". and setTitle("") in your code.
your final toolbar will look like
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"

android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:background="#drawable/toolbartitle"
local:theme="#style/MyMaterialTheme.Base"
local:popupTheme="#style/ThemeOverlay.AppCompat.Light" >
</android.support.v7.widget.Toolbar>
It was mistake done by me,i was checking with custom toolbar xml,but i already have toolbar in my activity_main.xml..Hope my answer will help others too

You should set the image src attribute rather than setting the imageview background drawable.
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/toolbartitle"
/>
You missed to show the source
android:src="#drawable/yourImage"
if not working try adding some genuine width and height instead of wrap content
android:layout_width="50dp"
android:layout_height="50dp"

How do I add buttons to recyclerView if attribute layout_below is taken?

My activitymain.xml file:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<include android:id="#+id/app_bar" layout="#layout/toolbar"/>
<view
android:id="#+id/recycler_view"
android:layout_below="#id/app_bar"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="android.support.v7.widget.RecyclerView"/>
</RelativeLayout>
Because my main.java file only contains Recyclerview and nothing else, i can't directly add 2 buttons into it.
I tried to add 2 imageButtons in the the recyclerView.
RecyclerView does not properly render itself in AndroidStudio - there is an issue from google.
So i can't see how exactly recycler view and toolbar(app_bar) stand to each other(I assume app_bar toolbar is below recyclerview(layout_below attribute) )
I suspect i should totally change the design of the app to finish it.
MainActivity.java, it only has recyclerview and adapter to it, it sends context into next SearchActivity:
public class MainActivity extends BaseActivity {
private static final String LOG_TAG = "mAIN ACTIVITY";
private List<Book> bookList = new ArrayList<>() ;
private RecyclerView recyclerView;
private BookRecyclerViewAdapter bookRecyclerViewAdapter;
private boolean FIRST_TIME_LAUNCH = false ;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
bookRecyclerViewAdapter = new BookRecyclerViewAdapter(new ArrayList<Book>(), MainActivity.this);
recyclerView.setAdapter(bookRecyclerViewAdapter);
}
If i try to add button it stands in upper left corner:
If you want the button to appear at the end of your list after the list has been scrolled down have a look at this question.
If you want the button below your list and be always visible, this is how you do it:
You 'squeeze in' the RecyclerView between the Button and the Toolbar giving it a layout_below and layout_above attribute:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<include android:id="#+id/app_bar" layout="#layout/toolbar"/>
<Button
android:id="#+id/button"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<view
android:id="#+id/recycler_view"
android:layout_below="#id/app_bar"
android:layout_above="#id/button"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="android.support.v7.widget.RecyclerView"/>
</RelativeLayout>
Try this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<include android:id="#+id/app_bar" layout="#layout/toolbar"/>
<view
android:id="#+id/recycler_view"
android:layout_below="#id/app_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
class="android.support.v7.widget.RecyclerView"/>
<Button
android:id="#+id/button"
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"
android:layout_below="#id/recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</RelativeLayout>

I followed http://android-developers.blogspot.de/2014/10/appcompat-v21-material-design-for-pre.html to use the toolbar, without fragment, it works perfectly, but when I use fragment, the fragment always overlays the content, and I cannot see toolbar when displaying fragment.
screen:
and when I starts another activity from the current one, the icon of the toolbar in the new activity doesn't show up. screen:
I use Android Support Library 21.0.3.
and the code in the MainActivity class:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
mLeftDrawerList = (ListView) findViewById(R.id.left_drawer);
mToolbar = (Toolbar) findViewById(R.id.toolbar);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
mNavigationDrawerAdapter=new ArrayAdapter<String>( MyActivity.this, android.R.layout.simple_list_item_1, data);
mLeftDrawerList.setAdapter(mNavigationDrawerAdapter);
if (mToolbar != null) {
mToolbar.setTitle("Home");
setSupportActionBar(mToolbar);
}
initDrawer();
final FragmentManager fragementMgr = getSupportFragmentManager();
FragmentTransaction transaction = fragementMgr.beginTransaction();
transaction.add(R.id.fragment_container, new MyFragment());
transaction.commit();
}
the layout xml:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainActivity"
android:layout_width="match_parent"
android:id="#+id/drawerLayout"
android:layout_height="match_parent">
<!-- activity view -->
<LinearLayout
android:layout_width="match_parent"
android:background="#fff"
android:layout_height="match_parent">
<include layout="#layout/toolbar" />
<FrameLayout android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<!-- navigation drawer -->
<RelativeLayout
android:layout_gravity="left|start"
android:layout_width="match_parent"
android:background="#fff"
android:layout_height="match_parent">
<ListView
android:id="#+id/left_drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="#eee"
android:background="#fff"
android:dividerHeight="1dp" />
</RelativeLayout>
</android.support.v4.widget.DrawerLayout>
code in MyFragment:
public class MyFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment, container, false);
final Button button = (Button) view.findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
Intent intent = new Intent(getActivity(), DetailActivity.class);
startActivity(intent);
}
});
// Inflate the layout for this fragment
return view;
}
}
layout xml for Fragment:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/hello_fragment"
android:textStyle="bold"
android:gravity="center"
android:layout_gravity="top"
android:textSize="18sp"
android:id="#+id/text"/>
<Button
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_below="#+id/text"
android:text="#string/open"
android:id="#+id/button"/>
</RelativeLayout>
The code in DetailActivity class:
public class DetailActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.detail_activity);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitle("Detail");
setSupportActionBar(toolbar);
}
}
layout for the detail activity:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent"
tools:context=".DetailActivity">
<include layout="#layout/toolbar" />
<TextView
android:layout_width="wrap_content"
android:textColor="#000"
android:text="Detail Activity Content"
android:layout_height="wrap_content" />
</LinearLayout>
can anyone help me out? thanks a lot!
Update: I updated the code and layout of the main activity according to reply from m iav.
new screen is blank now with the changes:
toolbar is a view in your layout , you can see it like textview ,now it is a textview overlay your fragment ,you use attrbibu to below it
so finally after checking the sample: MaterialEverywhere, I came with the solution with updating the layout:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainActivity"
android:layout_width="match_parent"
android:id="#+id/drawerLayout"
android:layout_height="match_parent">
<!-- activity view -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<include
android:id="#+id/toolbar"
layout="#layout/toolbar" />
<FrameLayout android:id="#+id/fragment_container"
android:layout_below="#id/toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
<!-- navigation drawer -->
<RelativeLayout
android:layout_gravity="left|start"
android:layout_width="match_parent"
android:background="#fff"
android:layout_height="match_parent">
<ListView
android:id="#+id/left_drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="#eee"
android:background="#fff"
android:dividerHeight="1dp" />
</RelativeLayout>
</android.support.v4.widget.DrawerLayout>
the trick is the parent layout of the toolbar and the content frame. Instead of LinearLayout, I use RelativeLayout. and it works now as expected.
anyway, I found such change from the SDK is over complex, with so many changes, and each can cause issues. It will be much better for the developers to have clean APIs with less all these tweaks.
This should be your main layout.
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainActivity"
android:layout_width="match_parent"
android:id="#+id/drawerLayout"
android:layout_height="match_parent">
<!-- activity view -->
<LinearLayout
android:layout_width="match_parent"
android:background="#fff"
android:layout_height="match_parent">
<include layout="#layout/toolbar" />
<FrameLayout android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<!-- navigation drawer -->
<RelativeLayout
android:layout_gravity="left|start"
android:layout_width="match_parent"
android:background="#fff"
android:layout_height="match_parent">
<ListView
android:id="#+id/left_drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="#eee"
android:background="#fff"
android:dividerHeight="1dp" />
</RelativeLayout>
</android.support.v4.widget.DrawerLayout>
And this should be your call to the new fragment:
transaction.add(R.id.fragment_container, new MyFragment())
transaction.commit();
Regarding your second question, a navigation drawer can't be shared among different activities. You have to use a new Fragment and keep the same Activity you're working in now.
