待意图演员活动时暂停只收到 [英] Pending intent extras are received only when activity is paused

问题描述

我是从我的 StateCh.java 发送额外的字符串挂起的意图 MainActivity 。我在上面的期望是未决的意图额外的抵（通知点击）时显示在 MainActivity 对话框。问题是，当我打开 MainActivity 然后我点击该通知有一个未决的意图和对话框内没有额外不显示。当我暂停 MainActivity （由pressing后退键），然后再次单击通知其按预期工作。

MainActivity.java：

 公共类MainActivity延伸活动{ // ...  @覆盖
保护无效onNewIntent（意向意图）{
    super.onNewIntent（意向）;    捆绑额外= getIntent（）getExtras（）。
    如果（临时演员！= NULL）{
        字符串值1 = extras.getString（信息）;
        Log.v（警报，值1）;        AlertDialog alertDialog =新AlertDialog.Builder（MainActivity.this）.create（）;
        alertDialog.setTitle（称号）;
        alertDialog.setMessage（值）;
        alertDialog.setButton（AlertDialog.BUTTON_POSITIVE，OK，新DialogInterface.OnClickListener（）{            公共无效的onClick（DialogInterface对话，诠释它）{                // startActivity（MainActivity.this.getIntent（））;            }
        }）;        alertDialog.show（）;
    }
 }
}
 

StateCh.java：

 公共类StateCh延伸服务{// ...   私人无效notificationU（标题字符串，字符串文本）{    //当用户点击展开的通知的意图发动
    意向意图=新意图（这一点，MainActivity.class）;
    intent.setFlags（Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP）;
    intent.putExtra（信息，东西）;
    intent.setAction（actionstring+ System.currentTimeMillis的（））;    的PendingIntent pendIntent = PendingIntent.getActivity（这一点，0，意向，PendingIntent.FLAG_UPDATE_CURRENT）;     通知noti2 =新NotificationCompat.Builder（本）
     .setContentTitle（职称）
     .setContentText（文本）
     .setSmallIcon（R.drawable.warning）
     .setContentIntent（pendIntent）
     。建立（）;     mNotificationManager =（NotificationManager）getSystemService（Context.NOTIFICATION_SERVICE）;
     mNotificationManager.notify（123456，noti2）;
    }    // ...}
 

解决方案

修改捆绑额外= getIntent（）getExtras（）;

要捆绑额外= intent.getExtras（）;

，或致电<一个href=\"http://developer.android.com/reference/android/app/Activity.html#setIntent%28android.content.Intent%29\"相对=nofollow> setIntent（意向）第一个

I'm sending extra string with pending intent from my StateCh.java to MainActivity. My expectation on it is to display dialog in MainActivity when pending intent with extra is arrived (notification is clicked). The problem is when i open the MainActivity and then I click the notification there is no extras inside pending intent and dialog isn't displayed. When I pause the MainActivity (by pressing back button) and click the notification again it works as expected.

MainActivity.java:

public class MainActivity extends Activity {

 //...

  @Override
protected void onNewIntent(Intent intent)   {
    super.onNewIntent(intent);

    Bundle extras = getIntent().getExtras();
    if(extras !=null) {
        String value1 = extras.getString("message");
        Log.v("alert", value1);

        AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();
        alertDialog.setTitle("title");
        alertDialog.setMessage(value1);
        alertDialog.setButton(AlertDialog.BUTTON_POSITIVE, "OK", new DialogInterface.OnClickListener() {

            public void onClick(DialogInterface dialog, int which) {

                //startActivity(MainActivity.this.getIntent());

            }
        });

        alertDialog.show();
    }
 }
}

StateCh.java:

public class StateCh extends Service {

//...

   private void notificationU(String title, String text)  {

    //The intent to launch when the user clicks the expanded notification
    Intent intent = new Intent(this, MainActivity.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
    intent.putExtra("message", "something");
    intent.setAction("actionstring" + System.currentTimeMillis());

    PendingIntent pendIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

     Notification noti2 = new NotificationCompat.Builder(this)
     .setContentTitle(title)
     .setContentText(text)
     .setSmallIcon(R.drawable.warning)
     .setContentIntent(pendIntent)
     .build();

     mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
     mNotificationManager.notify(123456, noti2);
    }

    // ...      

}

解决方案

Change Bundle extras = getIntent().getExtras();

To Bundle extras = intent.getExtras();

or call setIntent(intent) first
