Height of statusbar?

Solution 1:

Rect rectgle= new Rect();
Window window= getWindow();
window.getDecorView().getWindowVisibleDisplayFrame(rectgle);
int StatusBarHeight= rectgle.top;
int contentViewTop= 
    window.findViewById(Window.ID_ANDROID_CONTENT).getTop();
int TitleBarHeight= contentViewTop - StatusBarHeight;

   Log.i("*** Jorgesys :: ", "StatusBar Height= " + StatusBarHeight + " , TitleBar Height = " + TitleBarHeight);

Get the Height of the status bar on the onCreate() method of your Activity, use this method:

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

Solution 2:

For those, like me, who want to use it in your XML layouts:

<...
  android:layout_marginTop="@*android:dimen/status_bar_height"
  ... />

Don't be confused by that Android Studio (2.2 Preview 3 -- at the moment of writing) doesn't support this notion. The runtime does. I took it from the Google's source code.

Solution 3:

Although this is an old question, I found that the answer didn't work in onCreate():

I found this code from here which does work in the onCreate() method

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

I hope this helps to anyone that runs into this issue.

Solution 4:

The supported way of getting status bar height is to use WindowInsets class starting from API 21+:

customView.setOnApplyWindowInsetsListener((view, insets) -> {
    // Handle insets
    return insets.consumeSystemWindowInsets();
});

or WindowInsetsCompat for support libraries:

ViewCompat.setOnApplyWindowInsetsListener(customView, (view, insets) -> {
    // Handle insets
    return insets.consumeSystemWindowInsets();
});

You can also override the onApplyWindowInsets method inside the view:

public class CustomView extends View {
    @Override
    public WindowInsets onApplyWindowInsets(final WindowInsets insets) {
        final int statusBarHeight = insets.getStableInsetTop();
        return insets.consumeStableInsets();
    }
}

For further details, I'd recommend checking Chris Banes talk - Becoming a master window fitter (slides available here).

Solution 5:

You could also take the dimension of the status bar found in the dimens.xml file of android using the way that this blog post describes.

This can get the height of the statusbar without the need to wait for drawing.

Quoting the code from the blog post:

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

You need to put this method in a ContextWrapper class.
