我有同样的问题，必须在onCreate中获得状态栏的高度。这对我很有用。

private static final int LOW_DPI_STATUS_BAR_HEIGHT = 19;

private static final int MEDIUM_DPI_STATUS_BAR_HEIGHT = 25;

private static final int HIGH_DPI_STATUS_BAR_HEIGHT = 38;

在onCreate内部:

DisplayMetrics displayMetrics = new DisplayMetrics();
((WindowManager) getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay().getMetrics(displayMetrics);

int statusBarHeight;

switch (displayMetrics.densityDpi) {
    case DisplayMetrics.DENSITY_HIGH:
        statusBarHeight = HIGH_DPI_STATUS_BAR_HEIGHT;
        break;
    case DisplayMetrics.DENSITY_MEDIUM:
        statusBarHeight = MEDIUM_DPI_STATUS_BAR_HEIGHT;
        break;
    case DisplayMetrics.DENSITY_LOW:
        statusBarHeight = LOW_DPI_STATUS_BAR_HEIGHT;
        break;
    default:
        statusBarHeight = MEDIUM_DPI_STATUS_BAR_HEIGHT;
}

上面的答案对某些人不起作用的原因是，在视图准备好渲染之前，您无法获得视图的维度。使用一个OnGlobalLayoutListener来获得所说的维度，当你实际上可以:

@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
        }
    }
}

这是最可靠的方法。

切换全屏解决方案:

这个解决方案可能看起来像一个变通方法，但它实际上解释了你的应用程序是否全屏(也就是隐藏状态栏):

Display display = getWindowManager().getDefaultDisplay();
Point size = new Point(); display.getSize(size);
int barheight = size.y - findViewById(R.id.rootView).getHeight();

这样，如果你的应用程序目前是全屏的，barheight将等于0。

就我个人而言，我不得不使用这个来纠正绝对TouchEvent坐标，以解释状态栏:

@Override
public boolean onTouch(View view,MotionEvent event) {
    Display display = getWindowManager().getDefaultDisplay();
    Point size = new Point(); display.getSize(size);
    int YCoord = (int)event.getRawY() - size.y + rootView.getHeight());
}

那会得到绝对y坐标无论应用是否全屏。

享受

是的，当我尝试使用视图时，它提供了25px的结果。 以下是整个代码:

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);
            }
        }
    }
}

官方高度是24dp 正如谷歌在Android设计网页上正式声明的那样。

这也适用于引用链接

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