I am a new application developer. I did an example of (NavigationView drawer) and it works great.But my problem is I need to know how I can add it.
Like this:
I have add it as ImageButton in activity bar_main but I don't need it like that.
As such, I have problems like the following:
I have seen many examples that the icon is not added in this way that is not an ImageButton. It's like come from the system without any ImageButton .So I need do that.
Now if I work like that , it will get overlapped with the search icon.When pressing the search button, the drawer icon should disappear.
my code:
public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener{
static ImageButton menuRight;
private DrawerLayout drawer;
Toolbar toolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_m);
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
View headerView = navigationView.getHeaderView(0);
navigationView.setNavigationItemSelectedListener(this);
navigationView.bringToFront();
toolbar =findViewById(R.id.toolbar);
toolbar.setTitle("");
setSupportActionBar(toolbar);
drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
menuRight =(ImageButton) findViewById(R.id.leftRight);
menuRight.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
drawer.openDrawer(GravityCompat.START);
}
}
});
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
drawer.closeDrawers();
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
int id = item.getItemId();
if (id == R.id.nav_home) {
Intent i = new Intent(this, MainActivity.class);
startActivity(i);
} else if (id == R.id.nav_Politics) {
Intent i = new Intent(this, Ploysity.class);
startActivity(i);
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
return false;
}
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
}
super.onBackPressed();
}
}

You can implement left navigation something like this:
<androidx.drawerlayout.widget.DrawerLayout ...>
<!--Main content-->
<androidx.constraintlayout.widget.ConstraintLayout>
</androidx.constraintlayout.widget.ConstraintLayout>
<!--Left navigation-->
<com.google.android.material.navigation.NavigationView
android:layout_gravity="start"
app:headerLayout="#layout/navigation_header"
app:menu="#menu/navigation_view_menu"
... />
</androidx.drawerlayout.widget.DrawerLayout>
For more information: Material-Design-Navigation-View
if you wish to change the icon, then you need to add this line:
drawer.setHomeAsUpIndicator(R.drawable.ic_your_drawer_icon); //set your own
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDefaultDisplayHomeAsUpEnabled(false);
toggle.setDrawerIndicatorEnabled(false);
toggle.setHomeAsUpIndicator(R.drawable.ic_custom_drawer_icon);

I have a working navigation drawer that uses DrawerLayout on my activity. The problem is I can't put content inside it, so I used relative layout inside the drawerlayout. If I do that, the navigation drawer won't respond to any action. It just opens and closes.

If I remove the relative layout, the navigation drawer works fine. Everything is normal, but whenever I add the relative layout and textview back, clicking something from the navigation drawer will only close the drawer and not do anything.
You have given the TextView the ConstraintLayout attributes and you don't have ConstraintLayout.
However, you used RelativeLayout inside DrawerLayout. Your content should be placed inside CoordinatorLayout and not the DrawerLayout.
Anyways, make sure you have CoordinatorLayout as the root tag in this file: app_bar_home then place your content (without ConstraintLayout attributes in there(If you don't have ConstraintLayout))
I want my navigation drawer to open on an ImageView click, because I disabled the appbar, but it crashes my app when I click on the image. I get a NullPointerException error, but I do not know why... :/
Error:

The problem is that your mDrawerLayout is set to null here:
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
This happens as your layout R.layout.activity_home doesn't contain it.
Perhaps you can just do the following:
setContentView(R.layout.activity_navigation);
It's giving you NPE because you're using different content view
setContentView(R.layout.activity_home);
and your drawer is in activity_navigation.xml
You need to include your variable from parent activity. Don't create new variable. Make variables from parent activity public to access them. And don't initialize drawer three times in NavActivity
public class HomeActivity extends NavigationActivity {
//DrawerLayout mDrawerLayout; don't create this
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
ImageView icnMenu = findViewById(R.id.icon_menu);
icnMenu.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
drawer.openDrawer(GravityCompat.START); //use drawer from parent activity
}
});
}
I am using android studio 1.5.1. this version makes navigation drawer activity by its own:
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<include
layout="#layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_main"
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
But the slider menu opens from left. I want to set it to open from write.
so I changed the above code to this code:
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="right">
<include
layout="#layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="right"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_main"
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
so in the design mode, the drawer menu comes to the right position.
and I write this code (accourding to an answer in the stack overflow) in my MainActivity.java:
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
DrawerLayout drawer;
#Override

});

}

}
but when I run the program, in genymotion, the menu button is still on the left upper side and when I click on it, the program crash...
what is the problem and how can I set this menu to open from right?!
Try to not use ActionBarDrawerToggle class and in your R.menu.main, create a menu item (with a hamburger icon for example) which will be always visible for your Toolbar. When Activity is rendered, this menu item will be placed to the right in your Toolbar. So instead of using android.R.id.home, use your own menu item id when onOptionsItemSelected is called. And in your xml file, change android:layout_gravity="right" to android:layout_gravity="end". When you call drawer.openDrawer();, use the correct parameter accordingly for this method.
My main activity consists of a navigation drawer and switching between fragments was working fine. Now i tried to implement Material Searchview using this library which requires the toolbar to be set last inside the xml file. So now my serachview is working fine but onNavigationItemSelected stops working and i cant switch between fragments. If inside the xml i write navigation drawer below the toolbar navigation starts working again but searchview stops working. Please help me.

<android.support.design.widget.NavigationView

As you can see, GravityCompat don't let me to put right instead of END or START, and if I put it in the XML, it crash.
with the next error:
java.lang.IllegalArgumentException: No drawer view found with gravity LEFT
First of all replace on DrawerLayout the tools:openDrawer="start" with tools:openDrawer="end". Now your problem is on the toggle, which opens the left drawer, and because you have only right drawer it throws the exception. You can add your own button on the actionbar (on the right side) to open the drawer. To do that change your app_bar.xml like this
<?xml version="1.0" encoding="utf-8"?>
<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">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" />
<FrameLayout
android:id="#+id/drawer_button"
android:layout_width="50dp"
android:layout_height="?attr/actionBarSize"
android:layout_alignParentRight="true"
android:clickable="true">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal|center_vertical"
android:src="#mipmap/ic_drawer" />
</FrameLayout>
</RelativeLayout>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_main" />
</android.support.design.widget.CoordinatorLayout>
Then change your onCreate method from your Activity like this
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
findViewById(R.id.drawer_button).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// open right drawer
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.openDrawer(GravityCompat.END);
}
});
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
Also you can find the image for your drawer here or here.
I hope this will help you. :)
use a custom drawerLayout just like this :
public class TaskManagerDrawerLayout extends DrawerLayout {
public TaskManagerDrawerLayout(Context context) {
super(context);
}
public TaskManagerDrawerLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public TaskManagerDrawerLayout(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
try {
return super.onInterceptTouchEvent(ev);
} catch (IllegalArgumentException e) {
e.printStackTrace();
return false;
}
}
#Override
public void closeDrawer(int gravity) {
super.closeDrawer(GravityCompat.END);
}
#Override
public void openDrawer(int gravity) {
super.openDrawer(GravityCompat.END);
}
}
After implementing left side navigation drawer change the following properties.
tools:openDrawer="start" in DrawerLayout
android:layout_gravity="end" in NavigationView
toolbar.setNavigationIcon (R.color.transparent); mDrawerToggle.setDrawerIndicatorEnabled (false);
toolbar.setNavigationOnClickListener (new View.OnClickListener () { #Override public void onClick(View view) { if (mDrawerLayout.isDrawerOpen (Gravity.END)) { mDrawerLayout.closeDrawer (Gravity.END); } else { mDrawerLayout.openDrawer (Gravity.END); } } });
