如何在呼叫屏幕上添加彈出對話框?我將使用BroadcastReceiver來收聽來電並顯示它。我需要一個關於如何編寫允許通過來電進行對話的活動的想法。另外,如何讓對話框移動到屏幕的任何部分?我已經有BroadcastRceiver實施和執行其他功能,所以我可以只使用一個意向,並開始從這個BroadcastRceiver在呼叫屏幕上添加彈出對話框

謝謝,幫助。但是,如何使其可浮動,以便將其拖動到屏幕上的任何位置? – Slay 2014-12-07 11:43:04

試試這個

AlertDialog.Builder builder = new AlertDialog.Builder(context.getApplicationContext()); 
      LayoutInflater inflater = LayoutInflater.from(context); 
      View dialogView = inflater.inflate(R.layout.caller_dialog, null); 

      ImageView button = dialogView.findViewById(R.id.close_btn); 
      builder.setView(dialogView); 
      final AlertDialog alert = builder.create(); 
      alert.getWindow().requestFeature(Window.FEATURE_NO_TITLE); 
      alert.getWindow().setType(WindowManager.LayoutParams.TYPE_PHONE); 
      alert.setCanceledOnTouchOutside(true); 
      alert.show(); 
      WindowManager.LayoutParams lp = new WindowManager.LayoutParams(); 
      Window window = alert.getWindow(); 
      window.addFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE); 
      window.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND); 
      window.setGravity(Gravity.TOP); 
      lp.copyFrom(window.getAttributes()); 
      //This makes the dialog take up the full width 
      lp.width = WindowManager.LayoutParams.MATCH_PARENT; 
      lp.height = WindowManager.LayoutParams.WRAP_CONTENT; 
      window.setAttributes(lp); 
      button.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View view) { 
        //close the service and remove the from from the window 
        alert.dismiss(); 
       } 
      });
