Question

我想在工具栏下方显示一个ui，但问题是我的工具栏大小是50dp，如果我说我的布局边距从前50名然后对于某些Android版本它的工作。我认为在api 22之上我们还需要status_bar_height，其中包括工具栏高度。获取工具栏高度的最佳方法是什么，以便我可以在工具栏上方显示视图。我正在显示一个透明的覆盖屏幕

 int statusBar = getStatusBarHeight();
                RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(
                        RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
                layoutParams.setMargins(0, (statusBar + 50), 0, 0);
                MainRel.setLayoutParams(layoutParams);
                MainRel.setVisibility(View.VISIBLE);
}


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

使用此通用代码。覆盖OnWindowFocusChanged

  @Override
  public void onWindowFocusChanged(boolean hasFocus) {
      super.onWindowFocusChanged(hasFocus);
      int toolbarHeight = toolbar.getHeight();
      int statusBar = getStatusBarHeight();
      RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(
           RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
       layoutParams.setMargins(0, (statusBar + toolbarHeight), 0, 0);//you can use the toolbar height you got here. 
       MainRel.setLayoutParams(layoutParams); 
       MainRel.setVisibility(View.VISIBLE); 
  }
