Android：为API 19禁用并启用以编程方式拉动状态栏
我已经做了隐藏状态栏的操作，但不幸的是，我没有找到在状态栏已经隐藏后显示它的方法。我做了这么多的变通，但仍然没有成功 活动Android：为API 19禁用并启用以编程方式拉动状态栏,android,statusbar,Android,Statusbar,我已经做了隐藏状态栏的操作，但不幸的是，我没有找到在状态栏已经隐藏后显示它的方法。我做了这么多的变通，但仍然没有成功 活动 WindowManager manager = ((WindowManager) getApplicationContext() .getSystemService(Context.WINDOW_SERVICE)); WindowManager.LayoutParams localLayoutParams = new WindowMan
WindowManager manager = ((WindowManager) getApplicationContext()
.getSystemService(Context.WINDOW_SERVICE));
WindowManager.LayoutParams localLayoutParams = new WindowManager.LayoutParams();
localLayoutParams.type = WindowManager.LayoutParams.TYPE_SYSTEM_ERROR;
localLayoutParams.gravity = Gravity.TOP;
localLayoutParams.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE|
// this is to enable the notification to receive touch events
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
// Draws over status bar
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN;
localLayoutParams.width = WindowManager.LayoutParams.MATCH_PARENT;
localLayoutParams.height = (int) (50 * getResources()
.getDisplayMetrics().scaledDensity);
localLayoutParams.format = PixelFormat.TRANSPARENT;
customViewGroup view = new customViewGroup(this);
manager.addView(view, localLayoutParams);
class customViewGroup extends ViewGroup {
public customViewGroup(Context context) {
super(context);
}
@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
}
@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
return true;
}
}
我认为永久禁用状态栏很困难。我也在研究同样的概念，做了大量的研发，发现下面的代码很有用。如果用户试图展开状态栏，那么在一秒钟内，它会将状态栏拉回，并在oreo上工作。我试过不同的操作系统
