问题描述
我想有一个自定义来电屏幕，显示了当有来电时，如果呼叫被应答或得到驳回了电话停止振铃。
我搜索＃2几个职位给我看我如何可以实现，到目前为止，我几乎没有和屏幕被如何快速显示方面检查每一种方法的利弊后，我已经谈妥在窗口管理器的方法。
每当我称之为 wm.removeView（LY）我得到以下

我添加了一个标志，以纪念该视图已被添加。它确实需要关闭过程改进。

I want to have a custom incoming call screen that shows up when there is an incoming call, and get dismissed if the call is answered or the phone stops ringing.
I've searched several posts on Stackoverflow to show me how can I implement that, and so far I am nearly there and after checking pros and cons of each approach in terms of how fast the screen gets shown, I've settled on the WindowManager approach.
Whenever I call wm.removeView(ly) I get the stack below

解决方案
I've added a flag to mark that the view has been added. It does need to be improved off course.
switch (state){
case TelephonyManager.CALL_STATE_IDLE:
Log.d("DEBUG","IDLE");
if (viewCreated) {
wm.removeView(ly);
viewCreated = false;
}
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Log.d("DEBUG","OFFHOOK");
break;
case TelephonyManager.CALL_STATE_RINGING:
Log.d("DEBUG","RINGING");
if (!viewCreated){
WindowManager.LayoutParams params = new WindowManager.LayoutParams(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.TYPE_SYSTEM_ALERT|WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL|WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, PixelFormat.TRANSPARENT);
params.height= WindowManager.LayoutParams.MATCH_PARENT;
params.width= WindowManager.LayoutParams.MATCH_PARENT;
params.format=PixelFormat.TRANSPARENT;
params.gravity= Gravity.TOP;
ly=(LinearLayout)inflater.inflate(R.layout.activity_login,null);
wm.addView(ly, params);
viewCreated=true;
}
break;
}
