First off, this is not a duplicate of any of the "missing hamburger icons" questions here in SO. The linked question suggests to call the syncState method, but as clearly shown in the code below, I am not even using ActionBarDrawerToggle. I am developing for a device that runs Android Lollipop, and I want my Activity to have:
- A transparent toolbar so that the layout underneath can be seen
- A translucent status bar
- a custom icon for the hamburger icon
The top of my app should like this. As you can see, my main content has a blue image. I wanted my content to be underneath the toolbar, so I made my toolbar transparent.
I ran my app on the device and I was surprised to see that the hamburger icon for my drawer is not visible. But when I tap the upper-left corner of the screen, the drawer opens and I can see my menu items correctly.
My styles.xml looks like this:
<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:tools="http://schemas.android.com/tools">
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
<style name="AppTheme.Transparent">
<item name="windowActionBarOverlay">true</item>
<item name="android:windowContentOverlay">@null</item>
<item name="colorPrimary">@android:color/transparent</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@android:color/transparent</item>
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
</style>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light"/>
</resources>
And here's my MainActivity:
public class LoginActivity extends AppCompatActivity {
private DrawerLayout mDrawerLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
Toolbar toolbar = findViewById(R.id.custom_toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeAsUpIndicator(R.drawable.light_menu);
getSupportActionBar().setDisplayShowTitleEnabled(false);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
if (navigationView != null) {
setupDrawerContent(navigationView);
}
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
mDrawerLayout.openDrawer(GravityCompat.START);
return true;
}
return super.onOptionsItemSelected(item);
}
private void setupDrawerContent(NavigationView navigationView) {
navigationView.setNavigationItemSelectedListener(
new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
menuItem.setChecked(true);
mDrawerLayout.closeDrawers();
return true;
}
});
}
}
Here are the layouts I used. My activity_login.xml used in the activity:
<?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.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>
app_bar_main.xml contains my Toolbar which is inside a RelativeLayout. The content of my Activity is on another layout, 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"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:id="@+id/custom_toolbar"
android:minHeight="?attr/actionBarSize"
android:layout_height="wrap_content"
app:popupTheme="@style/AppTheme.PopupOverlay" />
<include layout="@layout/content_main" />
</RelativeLayout>
content_main.xml:
<?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">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:src="@drawable/top" />
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="@drawable/back_login" />
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="@drawable/front_login" />
</FrameLayout>
</RelativeLayout>
Here's my AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.myapp">
<application
android:name=".MyApp"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".LoginActivity"
android:theme="@style/AppTheme.Transparent">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Can anyone help me in fixing this? Thanks.
