无法删除重叠视图

我能解决这个问题，的问题是对话和相关可从广播接收器启动，但不推荐，因为活动运行View之前结束。

想实现覆盖像FB信使，truecaller等

public class IncomingCall extends BroadcastReceiver 
{ 
private Context pcontext; 
private static final String TAG = "CustomBroadcastReceiver"; 
TelephonyManager telephony; 
CustomPhoneStateListener customPhoneListener ; 
@Override 
public void onReceive(Context context, Intent intent) 
{ 
    pcontext = context; 
    Bundle extras = intent.getExtras(); 
    if (extras != null) { 
     String state = extras.getString(TelephonyManager.EXTRA_STATE); 
     Log.w("DEBUG", state); 

      telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE); 
      customPhoneListener = new CustomPhoneStateListener(); 
      telephony.listen(customPhoneListener, PhoneStateListener.LISTEN_CALL_STATE); 
      Bundle bundle = intent.getExtras(); 
      String phoneNr= bundle.getString("incoming_number"); 


    } 


} 
public class CustomPhoneStateListener extends PhoneStateListener 
{ 
    private static final String TAG = "CustomPhoneStateListener"; 
    Handler handler=new Handler(); 
    @Override 
    public void onCallStateChanged(int state, String incomingNumber) 
    { 

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

     WindowManager.LayoutParams params = new WindowManager.LayoutParams(
      LayoutParams.MATCH_PARENT, 
      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 = LayoutParams.MATCH_PARENT; 
     params.width = LayoutParams.MATCH_PARENT; 
     params.format = PixelFormat.TRANSLUCENT; 

     params.gravity = Gravity.BOTTOM; 

     RelativeLayout ly; 
     final LayoutInflater inflater = (LayoutInflater) pcontext.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     ly = (RelativeLayout) inflater.inflate(R.layout.dialog, null); 

     switch (state) 
     { 
     case TelephonyManager.CALL_STATE_RINGING: 
      Log.d("Call","RINGING"); 

      wm.addView(ly, params); 
      break; 

     case TelephonyManager.CALL_STATE_IDLE: 

       Log.d("Call","End"); 
       //WindowManager wm = (WindowManager) pcontext.getSystemService(Context.WINDOW_SERVICE); 

       if(ly!=null) 
       { 
        wm.removeView(ly); 
        ly = null; 
       } 
      break; 
     default: 
      break; 
     } 
     super.onCallStateChanged(state, incomingNumber); 
     telephony.listen(customPhoneListener, PhoneStateListener.LISTEN_NONE); 
    } 


}  
}

的addView工作正常，这里是日志

“查看未连接到窗口管理器”

我曾尝试创建布局programmaticaly太.. 但没有运气

也找不到生成的布局的编号

我从来没有尝试过直接通过broadcastReceiver。我一直在开新的活动，并在那里展示了重叠视图。请尝试一下。这里是如何显示我最近写的顶视图片段：http://stackoverflow.com/questions/18424613/cannot-click-on-edittext-after-adding-it-to-windowmanager/18433366# 18433366 –

但是，这将能够完成从广播接收机的另一个国家的活动 –

我知道我可以删除该活动的销毁视图 –

问题是，我们不能在广播接收器中使用对话框，它必须在另一个可以以意图开始的活动。

当BroadcastReceiver正在接收Intent广播时调用此方法。在此期间，您可以使用BroadcastReceiver上的其他方法查看/修改当前结果值。除非您明确要求使用registerReceiver（BroadcastReceiver，IntentFilter，String，android.os.Handler）在其他线程上调度此方法，否则此方法始终在其进程的主线程中调用。当它在主线程上运行时，您不应该在其中执行长时间运行的操作（在考虑接收器被阻塞并且候选者被终止之前系统允许超时10秒）。你不能在你的onReceive（）的实现中启动一个弹出对话框。

Android文档清楚地说明了这一点。
