如何从一个活动到TabHost活动返回一个结果（startActivityForResult）？ [英] How to return a result (startActivityForResult) from a Activity to TabHost Activity?

问题描述

我的A类调用startActivityForResult：A类是tabactivity的

my Class A calls a startActivityForResult: class A is activitygroup in the one tab of tabactivity

Intent intent = new Intent(this, ClassB.class);
startActivityForResult(intent, "STRING");

ClassB的是一个共同的活动，而不是在tabactivity，它是单独

ClassB is a common activity ,not in the tabactivity,it is alone

Intent intent = this.getIntent();
intent.putExtra("SOMETHING", "EXTRAS");
this.setResult(RESULT_OK, intent);
finish();

但在A级的onActivityResult没有收到毛岸英，不excute.if我把CLASSA出tabactivity的，我的应用程序就可以了。我读

but in Class A onactivityResult not receive anying,not excute.if i put classA out of the tabactivity,my app is ok. i have read

但不解决我的问题，有人可以在给一些建议，code是越多越好，谢谢

but not solve my problem,can somebody an give some advice ,code is more better,thank you

编辑：
A类我补充一下：

edit: in class A i add:

public class UpdateImageBroadcastReceiver extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent intent) {

            Log.i("temp","34353");


        }
    }



    /* (non-Javadoc)
     * @see android.app.Activity#onPause()
     */
    @Override
    protected void onPause() {
        // TODO Auto-generated method stub
        super.onPause();
        unregisterReceiver(updateImageBroadcastReceiver);

    }

    /* (non-Javadoc)
     * @see android.app.Activity#onResume()
     */
    @Override
    protected void onResume() {
        // TODO Auto-generated method stub
        super.onResume();

        updateImageFilter = new IntentFilter("ACTION_CHANGE_TAB");
        updateImageBroadcastReceiver = new UpdateImageBroadcastReceiver();
        registerReceiver(updateImageBroadcastReceiver, updateImageFilter);


    }

在B类：

   Intent intent = new Intent("ACTION_CHANGE_TAB");
                        intent.putExtra("path", f.getAbsolutePath());
                        sendBroadcast(intent);

                    //  FileListSelectActivity.this.setResult(RESULT_OK, intent);
                        finish();

但我不能打印：Log.i（温度，34353）;

but i cannot print: Log.i("temp","34353");

推荐答案

尝试使用广播接收机。您可以在活动B覆盖的onStop（），从广播活动B的事件和活动一听。

Try using broadcast receivers. You can override onStop() in activity B, broadcast an event from activity B and listen in activity A.
