WindowManager中的全屏

Question

这是我的代码:

params = new WindowManager.LayoutParams(
    WindowManager.LayoutParams.FLAG_FULLSCREEN,
    WindowManager.LayoutParams.FLAG_FULLSCREEN,
    WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
    WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
    PixelFormat.TRANSLUCENT);

wm = (WindowManager) getApplicationContext()
    .getSystemService(Context.WINDOW_SERVICE);

inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mTopView = (ViewGroup) inflater.inflate(R.layout.activity_invisible, null);

params.flags = WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE
    | WindowManager.LayoutParams.FLAG_DIM_BEHIND
    | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
    | WindowManager.LayoutParams.FLAG_FULLSCREEN;

if (keep==true) {
    int value = brightnessIntent.getExtras().getInt("value");
    float v=value/255.0f;
    params.dimAmount=0;
    params.alpha=v;
    rl = (RelativeLayout) mTopView.findViewById(R.id.window);

    getWindow().setAttributes(params);
    getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,

    WindowManager.LayoutParams.FLAG_FULLSCREEN);
    wm.addView(mTopView, params);
}

视图仍显示状态栏,mTopView是一个叠加窗口.如何让覆盖窗口覆盖整个屏幕？我不想"隐藏"状态栏,我希望我的活动叠加到它上面.

[编辑] 强调文字 我已经在我的onCreate()方法中有这个:

requestWindowFeature(Window.FEATURE_NO_TITLE); 
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

我的清单定义了一个全屏的风格.

这是目前的情况,我希望叠加层也扩展到状态栏.

Answer 1

我所要做的就是这个

params.flags=WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN| and the rest

这会将覆盖视图扩展到状态栏上.

此代码来自"Android Application 4 Development".你必须处理不同的Android版本

 // Hiding the Action Bar for different android versions 
    if (Build.VERSION.SDK_INT < 16) {
        // Hide the Action Bar on Android 4.0 and Lower
         getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
     }else {
        // Hide the Action Bar on Android 4.1 and Higher
        View decorView = getWindow().getDecorView();
        int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
        decorView.setSystemUiVisibility(uiOptions);
        android.app.ActionBar actionBar = getActionBar();
        actionBar.hide();
     }
