以下是添加WindowManager以保持在其他视图之上的代码。

工作正常。在窗口管理器内部布局并动态更新布局。但我无法更新视图。
private View mainView;
private WindowManager.LayoutParams params;
windowManager = (WindowManager) getSystemService(Service.WINDOW_SERVICE);
params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_FULLSCREEN,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.TOP | Gravity.LEFT;
params.x = 0;
params.y = 0;
windowManager.addView(mainView, params);
调用setText方法,没有异常,但视图未更新。任何人都可以在这里指出这个问题吗?

更新您要修改的特定视图:
// Get teh view params
WindowManager.LayoutParams paramNameTV = (WindowManager.LayoutParams) callerNameTv .getLayoutParams();
//update the view layout
windowManager.updateViewLayout(callerNameTv, paramNameTV );
