Translucent status bar in Android

Question

I am using the following layout (main_activity.xml)

Answer 1

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Window window = getWindow();
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            window.setStatusBarColor(Color.TRANSPARENT); } }

}

Use this in your activity. But changing the status bar color is only allowed after android L

Answer 2

Add these two lines in the onCreate of the activity that you want its layout status bar to be transparent

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
getWindow().setStatusBarColor(Color.TRANSPARENT);
}

No need to change your app theme or xml layout. In doing this your bar doesn't have to be transparent throughout your whole app if you don't want to.

Answer 3

The code below is making the status bar transparent but navigation bar opaque for API21+.

NOTE: you shouldn't be setting android:fitsSystemWindows="true".

override fun onCreate(savedInstanceState: Bundle?) {
      setupContentWindow()
      super.onCreate(savedInstanceState)
      setContentView(R.layout.activity_main)
}

fun setupContentWindow() {
    window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
    window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
    window.statusBarColor = Color.TRANSPARENT
    window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
}

Answer 4

It seems some people have grey status bar instead of transparent. To avoid this problem do the next in your activity:

override fun onCreate(savedInstanceState: Bundle?) {
    ...
    window.apply {
        clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
        addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
        statusBarColor = Color.TRANSPARENT
        decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
    }
}

Answer 5

try this:

add this in your app theme:

<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>

Set android:fitsSystemWindows=”true” to root container

Now in your activity onCreate():

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        Window w = getWindow();
        w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
    }

you can make the snackbar draw on top of screen:

Snackbar snack = Snackbar.make(parentLayout, str, Snackbar.LENGTH_LONG);
View view = snack.getView();
FrameLayout.LayoutParams params =(FrameLayout.LayoutParams)view.getLayoutParams();
params.gravity = Gravity.TOP;
view.setLayoutParams(params);
snack.show();

Please remove this line from your CoordinatorLayout:

android:fitsSystemWindows="true"
