当活动开始，获取的onActivityResult不叫当其完成 [英] onActivityResult gets called when Activity starts, not when its finished

问题描述

我写了一些选项卡的FragmentActivity。当我打电话的附加活动（我使用的用户可设置preferences）与startActivityForResult当我开始这个preference活动的onActivityResult被调用的方法（如果它在FragmentActivity或ListFragment无差异），但不当我完成它，因为我希望它（同样没有区别，如果它在FragmentActivity或ListFragment）。之后，我完成preference活动这种方法不会被调用的。

我的问题是，我想我刷新当前选项卡（并设置上次使用的标签ID）后，我完成了preference活动，我希望能够做到这一点的方法的onActivityResult。

这是该类创建preference活动：

 公共抽象类ListFragmentBase＆LT; I＆GT;扩展ListFragment工具
LoaderCallbacks＆LT;名单，LT; I＆GT;＆GT; {
 

这是方法我转发到这个类里面的preference活动：

 保护无效forwardTo preferences（INT currentTab）{
        意向意图=新意图（getActivity（），全球preferencesActivity.class）;
        。getActivity（）startActivityForResult（意向，10）;
}
 

这是被调用以上，但不是方法后，我完成了所谓的活动后调用的方法

  @覆盖
公共无效的onActivityResult（INT申请code，INT结果code，意图数据）{
    super.onActivityResult（要求code，结果code，数据）;
}
 

这是preference活动：

 公共类全球preferencesActivity延伸活动{
 

和该类你看我如何调用该方法完成内：

  TextView的confirmSettings =（TextView中）view.findViewById（R.id.confirm_settings）;
confirmSettings.setTextSize（preferenceHelper.getSizeHeader（getApplicationContext（）））;
    confirmSettings.findViewById（R.id.confirm_settings）.setOnClickListener（新View.OnClickListener（）{
        @覆盖
        公共无效的onClick（查看视图）{
            如果（BaseFragmentActivity.lastActivity！= NULL）{
                BaseFragmentActivity.lastActivity.onRefreshData（）;
        }
            组件名callingActivity = getCallingActivity（）;
            全球preferencesActivity.this.finish（）;
        }
    }）;
 

解决方案

这是Android系统中的错误

<一个href=\"http://stackoverflow.com/questions/3354955/onactivityresult-called-$p$pmaturely\">onActivityResult()所谓prematurely

我不知道你使用的版本，如果它已经解决/修正

i wrote a FragmentActivity with some tabs. when i call an additional activity (which i use for setting user-preferences) with startActivityForResult (no differences if its in FragmentActivity or in ListFragment) the method onActivityResult gets called when i starts this preference-activity, but not when i finish it, as i would expect it (again no differences if its in FragmentActivity or in ListFragment). after i finish the preference-activity this method does not get called at all.

my problem is that i want to refresh my current tab (and set the last used tab id) after i finished the preference activity and i hoped to be able to do this in the onActivityResult method.

this is the class creating the preference-activity:

public abstract class ListFragmentBase<I> extends ListFragment implements
LoaderCallbacks<List<I>> {

this is the method forwarding me to the preference activity inside this class:

protected void forwardToPreferences(int currentTab){            
        Intent intent = new Intent(getActivity(), GlobalPreferencesActivity.class);
        getActivity().startActivityForResult(intent, 10);
}

this is the method that gets called after calling the method above but not after i finished the called activity

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
}

this is the preference-activity:

public class GlobalPreferencesActivity extends Activity {

and inside that class you see how i call the finish method:

TextView confirmSettings = (TextView) view.findViewById(R.id.confirm_settings);
confirmSettings.setTextSize(PreferenceHelper.getSizeHeader(getApplicationContext()));
    confirmSettings.findViewById(R.id.confirm_settings).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {    
            if(BaseFragmentActivity.lastActivity != null){
                BaseFragmentActivity.lastActivity.onRefreshData();
        }
            ComponentName callingActivity = getCallingActivity();
            GlobalPreferencesActivity.this.finish();
        }
    });

解决方案

It is a bug of Android

onActivityResult() called prematurely

and

Why does result from startActivityForResult come before activity really starts?

I don't know which version you use and if it has been solved/corrected
