I Implemented the Navigation Drawer in my Fragment but it always shows a grey padding above it .Same was the case with Fragment but i removed it by adding android:fitsSystemWindows="false". But this fails to remove the padding above the Navigation Drawer . How can i avoid this ?
This is my Fragment :
import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.AppCompatActivity;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import com.dummy.R;
public class QueriesActivity extends Fragment {
Context context;
DrawerLayout mDrawerLayout;
boolean mSlideState=false;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.activity_queries, container, false);
return rootView;
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
context = getActivity();
mDrawerLayout = (DrawerLayout)view.findViewById(R.id.queries_drawer_layout);
setHasOptionsMenu(true);
((AppCompatActivity) getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(true);
mDrawerLayout.setDrawerListener(new DrawerLayout.DrawerListener() {
#Override
public void onDrawerSlide(View view, float v) {
}
#Override
public void onDrawerOpened(View view) {
mSlideState=true;
}
#Override
public void onDrawerClosed(View view) {
mSlideState=false;
}
#Override
public void onDrawerStateChanged(int i) {
}
});
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater menuInflater) {
menuInflater.inflate(R.menu.menu_filter, menu);
super.onCreateOptionsMenu(menu, menuInflater);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.search:
if(mSlideState){
mDrawerLayout.closeDrawer(Gravity.END);
}else{
mDrawerLayout.openDrawer(Gravity.END);
}
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}
I want to implement this as attached in the image.

I have tried checking all the related posts from the internet and can't find a decent tutorial on YT. Can someone tell me what is going on here?
Add following line in onCreateView() method
setHasOptionsMenu(true)
Also add below line in onViewCreated() method
(activity as AppCompatActivity?)!!.setSupportActionBar(customToolbar as Toolbar?)
Where customToolBar is the id of the toolbar added in xml file
Add this in your onCreateView method
setHasOptionsMenu(true);

I started writing an app for Android. I have a problem with the Animation of the NavigationDrawer icon at the top left. It works correctly when the application is launched for the first time but when I pick an item from the list in the NavgationDrawer its icon stays in the "open" state even though the `NavigationDrawer closes as it should.
Here is my MainActivity:
import android.app.*;
import android.os.*;
import android.view.*;
import android.widget.*;
import android.app.ActionBar;
import android.os.Bundle;
import android.app.Activity;
import android.support.v4.app.ActionBarDrawerToggle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTransaction;
import android.support.v4.widget.DrawerLayout;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.content.res.*;
public class MainActivity extends FragmentActivity {
ActionBarDrawerToggle icon;
final String[] listContent ={"Accueil","Fiche technique","Pilotes","Ecuries"};
final String[] fragments ={
"com.mycompany.f1holo.MainPageFragment",
"com.mycompany.f1holo.FirstFragment",
"com.mycompany.f1holo.SecondFragment",
"com.mycompany.f1holo.ThirdFragment"};
private ActionBarDrawerToggle actionBarDrawerToggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ArrayAdapter<String> ad = new ArrayAdapter<String>(getActionBar().getThemedContext(), android.R.layout.simple_list_item_1, listContent);
final DrawerLayout drawer = (DrawerLayout)findViewById(R.id.drawer_layout);
final ListView list = (ListView) findViewById(R.id.drawer);
actionBarDrawerToggle = new ActionBarDrawerToggle(
this,
drawer,
R.drawable.navdrawer,
R.string.open,
R.string.close);
drawer.setDrawerListener(actionBarDrawerToggle);
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
list.setAdapter(ad);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView parent, View view, final int position, long id) {
drawer.setDrawerListener( new DrawerLayout.SimpleDrawerListener(){
#Override
public void onDrawerClosed(View drawerView){
super.onDrawerClosed(drawerView);
FragmentTransaction transition = getSupportFragmentManager().beginTransaction();
transition.replace(R.id.mains, Fragment.instantiate(MainActivity.this, fragments[position]));
transition.commit();
}
});
drawer.closeDrawer(list);
}
});
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
actionBarDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
actionBarDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (actionBarDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
switch (item.getItemId())
{
case R.id.mainMenuAbout:
Toast.makeText(this, "F1 Holo", Toast.LENGTH_SHORT).show();
return true;
case R.id.mainMenuQuitter:
finish();
}
return super.onOptionsItemSelected(item);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main_menu, menu);
getMenuInflater().inflate(R.menu.main_about, menu);
return true;
}
}
And here is my FirstFragment:
import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class FirstFragment extends Fragment {
public static Fragment newInstance(Context context) {
FirstFragment frag = new FirstFragment();
return frag;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
ViewGroup root = (ViewGroup) inflater.inflate(R.layout.first_fragment_layout, null);
return root;
}
}
I have found the solution and it is so obvious I could kick myself for not noticing before...
The problem is here:
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView parent, View view, final int position, long id) {
drawer.setDrawerListener( new DrawerLayout.SimpleDrawerListener() {
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
FragmentTransaction transition = getSupportFragmentManager().beginTransaction();
transition.replace(R.id.mains, Fragment.instantiate(MainActivity.this, fragments[position]));
transition.commit();
}
});
drawer.closeDrawer(list);
}
});
In this OnClickListener you are setting a new SimpleDrawerListener and therefore overriding this line:
drawer.setDrawerListener(actionBarDrawerToggle);
This disconnects the ActionBarDrawerToogle from the DrawerLayout and as a result stops the animations from playing... This is all you need:
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView parent, View view, final int position, long id) {
FragmentTransaction transition = getSupportFragmentManager().beginTransaction();
transition.replace(R.id.mains, Fragment.instantiate(MainActivity.this, fragments[position]));
transition.commit();
drawer.closeDrawer(list);
}
});
Why would you want to do this anyway? It just causes a delay between the user picking the item and the content actually changing. If it is because of performance issues - maybe that the close animation of the NavigationDrawer is not playing correctly - then doing something like this might be appropriate but in any case if you decide to implement this do it like this:
First create global variable called drawerItemSelection:
private String drawerItemSelection = null;
And then implement your ItemClickListener like this:
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView parent, View view, final int position, long id) {
drawerItemSelection = fragments[position];
drawer.closeDrawer(list);
}
});
And finally in your onCreate() method implement the ActionBarDrawerToogle like this:
actionBarDrawerToggle = new ActionBarDrawerToggle(this, drawer, R.drawable.navdrawer, R.string.open, R.string.close) {
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
if(drawerItemSelection != null) {
FragmentTransaction transition = getSupportFragmentManager().beginTransaction();
transition.replace(R.id.mains, Fragment.instantiate(MainActivity.this, drawerItemSelection));
transition.commit();
drawerItemSelection = null;
}
}
};
If you have any further questions feel free to ask!
Issue that I have found reproduce only on devices and emulators with API level 16 (4.1.2) + support library v4.
There is quite complicated structure: ActionBarActivity->Fragment(Outer)->ViewPager->Fragment(Inner, several instances).Each fragment inside ViewPager (Inner Fragments) changes ActionBar title and adds its own MenuItems. After replacing Outer fragment (that owns ViewPager) with another one (the same class: Outer) MenuItems (that first Inner fragment has added) become invisible and title trimmed(view that contain title do not re-sized). After swiping to the second Inner fragment and back everything return in proper state.
