在有一个以上的活动Android应用程序处理onActivityResult [英] Handling onActivityResult in Android app having more than one activity

问题描述

在我的Andr​​oid应用程序，我有过意向创建两个其他子activites主要活动。现在，无论是子活动返回结果的主要活动。在我的主要活动， 我怎么处理两个onActivityResult（INT申请code，INT结果code，意图数据），因为它不能有两种方法具有相同的名称在给定的类。希望我的问题是清楚的。

In my android app, I have a main activity which creates two other sub activites through intent. Now, both the sub activity return result to the main activity. In my main activity, how do I handle two "onActivityResult(int requestCode, int resultCode, Intent data)" since it cant have two methods with same name in a given class. Hope my question is clear..

感谢

推荐答案

这就是请求code 是什么。所以，你有这样的设置

That's what the requestCode is for. So you'd have a setup like this

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    super.onActivityResult(requestCode, resultCode, data);
    switch(requestCode)
        case ACTIVITY1:
           if(resultCode == RESULT_OK)
              Toast.makeText(getApplicationContext(), "Activity 1 returned OK", Toast.LENGTH_LONG).show();
           break;
        case ACTIVITY2:
           if(resultCode == RESULT_OK)
              Toast.makeText(getApplicationContext(), "Activity 2 returned OK", Toast.LENGTH_LONG).show();
           break;
}

在哪里活动1和活性2在你的活动常数。你会打电话给他们，像这样：

Where ACTIVITY1 and ACTIVITY2 are constants in your Activity. You'd call them like so:

startActivityForResult（activity1Intent，活动1）;

和

startActivityForResult（activity2Intent，活性2）;
