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;
}

240x320 - 20px 320x480 - 25px 480x800+ - 38px

根据材料指南;状态栏高度为24dp。

如果你想获得状态栏的高度，你可以使用下面的方法:

private static int statusBarHeight(android.content.res.Resources res) {
    return (int) (24 * res.getDisplayMetrics().density);
}

可以从activity中调用:

statusBarHeight(getResources());

在Android 4.1及更高版本上，你可以将应用程序的内容设置为显示在状态栏后面，这样当状态栏隐藏或显示时，内容不会调整大小。为此，使用SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN。你可能还需要使用SYSTEM_UI_FLAG_LAYOUT_STABLE来帮助你的应用保持一个稳定的布局。

当您使用这种方法时，您有责任确保应用程序UI的关键部分(例如，地图应用程序中的内置控件)最终不会被系统栏覆盖。这可能会使你的应用程序无法使用。在大多数情况下，你可以通过添加android:fitsSystemWindows属性到你的XML布局文件，设置为true来处理这个问题。这将调整父ViewGroup的填充，为系统窗口留出空间。这对于大多数应用程序来说已经足够了。

In some cases, however, you may need to modify the default padding to get the desired layout for your app. To directly manipulate how your content lays out relative to the system bars (which occupy a space known as the window's "content insets"), override fitSystemWindows(Rect insets). The fitSystemWindows() method is called by the view hierarchy when the content insets for a window have changed, to allow the window to adjust its content accordingly. By overriding this method you can handle the insets (and hence your app's layout) however you want.

默认高度是25dp。在Android Marshmallow (API 23)中，高度降低到24dp。

更新:请注意，自从缺口和打孔的时代开始，使用静态高度的状态栏不再工作。请使用窗口插页代替!

试试这个:

    Rect rect = new Rect();
    Window win = this.getWindow();
    win.getDecorView().getWindowVisibleDisplayFrame(rect);
    int statusBarHeight = rect.top;
    int contentViewTop = win.findViewById(Window.ID_ANDROID_CONTENT).getTop();
    int titleBarHeight = contentViewTop - statusBarHeight;
    Log.d("ID-ANDROID-CONTENT", "titleBarHeight = " + titleBarHeight );

它没有为我工作在onCreate方法的活动，但当我把它放在onClickListener，并给我一个25的测量
