Android获得statusBar高度

     在画UI过程中，有些情况下需要知道statusBar高度：

网上有些方法是这样的：

Rect frame = new Rect();getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);int statusBarHeight = frame.top;Log.v("@@@@@@", "the statusbar Height is : " + statusBarHeight);

类似：

int contentTop = getWindow().findViewById(Window.ID_ANDROID_CONTENT).getTop();//statusBarHeight是上面所求的状态栏的高度int titleBarHeight = contentTop - statusBarHeight;Log.v("@@@@@@", "the titleBar Height is : " + titleBarHeight);

或者：

Rect rect = new Rect();        MainActivity.this.getWindow().getDecorView().getWindowVisibleDisplayFrame(rect);        View view = MainActivity.this.getWindow().findViewById(Window.ID_ANDROID_CONTENT);        int topS = rect.top;//状态栏高度        int topT = rect.height() - view.getHeight();                Log.v("@@@@@@", "the statusbar Height is : " + topS);        Log.v("@@@@@@", "the titleBar Height is : " + topT);

在我的手机上，均不行。

后：

public static int getStatusBarHeight(Context context){        Class<?> c = null;        Object obj = null;        Field field = null;        int x = 0, statusBarHeight = 0;        try {            c = Class.forName("com.android.internal.R$dimen");            obj = c.newInstance();            field = c.getField("status_bar_height");            x = Integer.parseInt(field.get(obj).toString());            statusBarHeight = context.getResources().getDimensionPixelSize(x);             Log.v("@@@@@@", "the status bar height is : " + statusBarHeight);        } catch (Exception e1) {            e1.printStackTrace();        }         return statusBarHeight;    }

经测试可行。
