android 4.2.2+上的覆盖状态栏

Question

我想覆盖android状态栏.就我而言,它位于顶部.我不想叠加或隐藏导航栏.

注意:解决方案必须适用于android 4.2.2+.我更喜欢非root设备的答案.

我搜索了许多SO问题和答案,但没有一个适用于4.2.2.

下面是我的代码,但它不消耗触摸事件.这就是状态栏打开其面板的原因.我不想要这个.

@Override 
public void onCreate() {
    super.onCreate();

    windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);

    int statusBarHeight = (int) Math.ceil(25 * getResources().getDisplayMetrics().density);

    overlay = new Button(this);
    overlay.setBackgroundColor(Color.GREEN);
    overlay.setOnTouchListener(new OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            Log.i("StatusBar", "touched");
            return false;
        }
    });

    WindowManager.LayoutParams params = new WindowManager.LayoutParams(
            WindowManager.LayoutParams.FILL_PARENT,
            statusBarHeight,
            WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
            WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE|
            WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL|
            WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH|
            WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
            PixelFormat.TRANSLUCENT);

    params.gravity = Gravity.TOP | Gravity.RIGHT;

    windowManager.addView(overlay, params);

}

@Override
public void onDestroy() {
    super.onDestroy();
    if (overlay != null) windowManager.removeView(overlay);
}

在主要活动中我开始服务:

startService(new Intent(this, StatusBarService.class));

并在AndroidManifest.xml中添加权限:

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>

现在证明它可以完成,它适用于4.2.2: 玩Google - MobiLock

怎么样？

Answer 1

尝试重复后,这对我来说:

int statusBarHeight = (int) Math.ceil(25 * getResources().getDisplayMetrics().density);

WindowManager.LayoutParams params = new WindowManager.LayoutParams(WindowManager.LayoutParams.FILL_PARENT,
            statusBarHeight,
            WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,
            WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE|
            WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL|
            WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
            PixelFormat.TRANSLUCENT);

它适用于4.2.2和4.4.2
