Height of status bar in Android [duplicate]

Answer 1

The reason why the top answer does not work for some people is because you cannot get the dimensions of a view until it is ready to render. Use an OnGlobalLayoutListener to get said dimensions when you actually can:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    final ViewGroup decorView = (ViewGroup) this.getWindow().getDecorView();
    decorView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            if (Build.VERSION.SDK_INT >= 16) {
                decorView.getViewTreeObserver().removeOnGlobalLayoutListener(this);
            } else {
                // Nice one, Google
                decorView.getViewTreeObserver().removeGlobalOnLayoutListener(this);
            }
            Rect rect = new Rect();
            decorView.getWindowVisibleDisplayFrame(rect);
            rect.top; // This is the height of the status bar
        }
    }
}

This is the most reliable method.

Answer 2

I've merged some solutions together:

public static int getStatusBarHeight(final Context context) {
    final Resources resources = context.getResources();
    final int resourceId = resources.getIdentifier("status_bar_height", "dimen", "android");
    if (resourceId > 0)
        return resources.getDimensionPixelSize(resourceId);
    else
        return (int) Math.ceil((VERSION.SDK_INT >= VERSION_CODES.M ? 24 : 25) * resources.getDisplayMetrics().density);
    }

another alternative:

    final View view = findViewById(android.R.id.content);
    runJustBeforeBeingDrawn(view, new Runnable() {
        @Override
        public void run() {
            int statusBarHeight = getResources().getDisplayMetrics().heightPixels - view.getMeasuredHeight();
        }
    });

Answer 3

Official height is 24dp, as is stated officially by Google on Android Design webpage.

Answer 4

Yes when i try it with View it provides the result of 25px. Here is the whole code :

public class SpinActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        LinearLayout lySpin = new LinearLayout(this);
        lySpin.setOrientation(LinearLayout.VERTICAL);       
        lySpin.post(new Runnable()
        {
            public void run()
            {
                Rect rect = new Rect();
                Window window = getWindow();
                window.getDecorView().getWindowVisibleDisplayFrame(rect);
                int statusBarHeight = rect.top;
                int contentViewTop = 
                    window.findViewById(Window.ID_ANDROID_CONTENT).getTop();
                int titleBarHeight = contentViewTop - statusBarHeight;
                System.out.println("TitleBarHeight: " + titleBarHeight 
                    + ", StatusBarHeight: " + statusBarHeight);
            }
        }
    }
}

Answer 5

this also work with the refrence link

public int getStatusBarHeight() {
  int result = 0;
  int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
  if (resourceId > 0) {
      result = getResources().getDimensionPixelSize(resourceId);
  }
  return result;
}
