I have read a lot of answers here but could not manage to do it. I want all of my activities to have a drawer. Inside the drawer i have a ListView which contains all of the activities that the drawer should open. This is the implementation of the drawer:
public abstract class DrawerActivity extends BaseActivity {
private DrawerLayout drawerLayout;
private ListView drawerList;
private ActionBarDrawerToggle drawerToggle;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.base_drawer_layout);
drawerLayout = findViewById(R.id.drawer_layout);
drawerList = findViewById(R.id.left_drawer);
final ArrayList<String> elements = new ArrayList<>();
elements.add("My tasks");
elements.add("Issues");
drawerList.setAdapter(new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, elements));
drawerList.setOnItemClickListener(createOnDrawerItemClickListener());
// enable ActionBar app icon to behave as action to toggle nav drawer
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
// ActionBarDrawerToggle ties together the the proper interactions
// between the sliding drawer and the action bar app icon
drawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
drawerLayout, /* DrawerLayout object */
R.string.drawer_open, /* "open drawer" description for accessibility */
R.string.drawer_close /* "close drawer" description for accessibility */
) {
public void onDrawerClosed(View view)
{
getSupportActionBar().setTitle("TITLE");
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView)
{
getSupportActionBar().setTitle("Title");
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
drawerLayout.addDrawerListener(drawerToggle);
}
/**
* When using the ActionBarDrawerToggle, you must call it during
* onPostCreate() and onConfigurationChanged()...
*/
@Override
protected void onPostCreate(Bundle savedInstanceState)
{
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
drawerToggle.syncState();
}
@Override
public void onConfigurationChanged(Configuration newConfig)
{
super.onConfigurationChanged(newConfig);
// Pass any configuration change to the drawer toggles
drawerToggle.onConfigurationChanged(newConfig);
}
@Override
public boolean onOptionsItemSelected(MenuItem item)
{
if (drawerToggle.onOptionsItemSelected(item))
return true;
return super.onOptionsItemSelected(item);
}
protected abstract DrawerItemClickListener createOnDrawerItemClickListener();
protected ListView drawerList()
{
return drawerList;
}
protected DrawerLayout drawerLayout()
{
return drawerLayout;
}
}
This is the drawer layout xml file
<?xml version="1.0" encoding="utf-8"?>
<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="#274"/>
</android.support.v4.widget.DrawerLayout>
Lets say i have currently two activities, My Tasks and Issues and both of them extend DrawerActivity. If i am in the Issues activity, how can i open the My Tasks activity through that drawer?
All activities that extend DrawerActivity implements createOnDrawerItemClickListener() which inside creates a new fragment with the layout of the the activity that implements DrawerActivity, which i'm pretty sure is wrong.
Example implementation:
@Override
protected DrawerItemClickListener createOnDrawerItemClickListener()
{
return new DrawerItemClickListener(position ->
{
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, new TaskFragment()).commit();
drawerList().setItemChecked(position, true);
drawerLayout().closeDrawer(drawerList());
});
}
And the DrawerItemClickListener:
public class DrawerItemClickListener implements ListView.OnItemClickListener {
private FragmentStrategy fragmentStrategy;
public DrawerItemClickListener(final FragmentStrategy fragmentStrategy)
{
this.fragmentStrategy = fragmentStrategy;
}
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
fragmentStrategy.showFragment(position);
}
public interface FragmentStrategy {
void showFragment(final int position);
}
}
How can i make this work?
In your case adding fragment will be the best solution.
create a fragment BlankFragment.java
public class BlankFragment extends Fragment {
public BlankFragment() {
// Required empty public constructor
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_blank, container, false);
}
}
and create fragment_black.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.above_inc.shyam.drawer.BlankFragment">
<!-- TODO: Update blank fragment layout -->
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="@string/hello_blank_fragment" />
</FrameLayout>
now replace your method
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
Fragment fragment = null;
if (id == R.id.nav_camera) {
// Handle the camera action
fragment = new BlankFragment();
} else if (id == R.id.nav_gallery) {
} else if (id == R.id.nav_slideshow) {
} else if (id == R.id.nav_manage) {
} else if (id == R.id.nav_share) {
} else if (id == R.id.nav_send) {
}
if (fragment != null) {
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.frame_container, fragment).commit();
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
add below code in your content_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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="com.above_inc.shyam.drawer.MainActivity"
tools:showIn="@layout/app_bar_main">
<FrameLayout
android:id="@+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</RelativeLayout>
you can also add more fragment to other options same as camera in above code
