如何在Fragment中调用OnActivityResult及其工作方式? [英] How can I call OnActivityResult inside Fragment and how it work?

问题描述

我想知道是否可以在onActivityResult()上在Fragment中使用，如果可以，那么它如何工作，请举例说明.

I want to know is it possible on onActivityResult()to use inside Fragment and if yes then how it works please explain with example.

推荐答案

在您的片段中，您需要调用:

Within your fragment, you need to call:

startActivityForResult(myIntent, MY_INTENT_REQUEST_CODE);

其中myIntent是您已经定义的意图，MY_INTENT_REQUEST_CODE是您在此片段中定义为全局变量的int常量，作为此意图的请求代码.

where myIntent is the intent you already defined, and MY_INTENT_REQUEST_CODE is the int constant you defined in this fragment as a global variable as the request code for this intent.

然后，仍在片段中，您需要重写此方法:

And then, still inside your fragment, you need to override this method:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
   //super.onActivityResult(requestCode, resultCode, data); comment this unless you want to pass your result to the activity.
}
