큐는 5 초마다 점검되고

을 다음과 같이 항목이있는 경우에 팝업의 시작 활동을 발행 : - 메시지가 도착하면 의도 팝업을 보여주기 시작하지만 다음과 같은 오류가 표시됩니다 다음과 같이

SMSPopup.msg = main.msgs.get(0); 
     Intent testActivityIntent = new Intent(context.getApplicationContext(), com.andy.tabletsms.work.SMSPopup.class); 
    testActivityIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
    context.startActivity(testActivityIntent); 

SMSPopup 클래스 보인다 : 당신은 너무 일찍 팝업을 표시하는

package com.andy.tabletsms.work; 


import com.andy.tabletsms.tablet.R; 

import android.app.Activity; 
import android.content.Context; 
import android.os.Bundle; 
import android.view.Gravity; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.view.ViewGroup; 
import android.widget.Button; 
import android.widget.PopupWindow; 
import android.widget.Toast; 

public class SMSPopup extends Activity{ 

public static String msg; 
private PopupWindow pw; 

@Override 
public void onCreate(Bundle bundle){ 
    super.onCreate(bundle); 
    Toast.makeText(getApplicationContext(), msg, Toast.LENGTH_LONG).show(); 
    LayoutInflater inflater = LayoutInflater.from(this); 
    // inflate our view from the corresponding XML file 
    View layout = inflater.inflate(R.layout.popup, (ViewGroup)findViewById(R.id.popup_menu_root)); 
    // create a 100px width and 200px height popup window 
    pw = new PopupWindow(layout, 100, 200, true); 
    // set actions to buttons we have in our popup 
    Button button1 = (Button)layout.findViewById(R.id.popup_menu_button1); 
    button1.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View vv) { 
      // close the popup 
      pw.dismiss(); 
     } 
    }); 
    Button button2 = (Button)layout.findViewById(R.id.popup_menu_button2); 
    button2.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View vv) { 
     Toast.makeText(getApplicationContext(), msg, Toast.LENGTH_LONG).show(); 
     } 
    }); 
    Button button3 = (Button)layout.findViewById(R.id.popup_menu_button3); 
    button3.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View vv) { 
      finish(); 
     } 
    }); 
    // finally show the popup in the center of the window 


    pw.showAtLocation(layout, Gravity.CENTER, 0, 0); 

} 
} 

Answer 1

다른 게시물은 너무 일찍 팝업을 시도하는 문제를 지적했습니다. 그러나 나는 또한 당신이 정말이 일을해서는 안된다 생각 :

public static String msg; 

및

SMSPopup.msg = main.msgs.get(0); 

이 다른 Activity에 데이터를 전달하는 올바른 방법이 아니다. 이처럼 Intent상의 Extra로 데이터를 설정해야합니다

이

Intent testActivityIntent = new Intent(context.getApplicationContext(), com.andy.tabletsms.work.SMSPopup.class); 
testActivityIntent.putExtra("com.andy.tabletsms.message", main.msgs.get(0)); 
testActivityIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
context.startActivity(testActivityIntent); 

그런 다음 대상 Activity에서 메시지를 검색 할 수 있습니다

private String msg; 
... 
Intent intent = getIntent(); 
if (intent != null){ 
    Bundle bundle = intent.getExtras(); 
    if (bundle != null){ 
     msg = bundle.getString("com.andy.tabletsms.message"); 
    } 
} 

Answer 2

활동의 윈도우가 표시됩니다 후에 만 ​​표시 할 수 있습니다. Runnable을 게시하여 팝업을 표시 할 수 있습니다.
