如何在Fragment中调用OnActivityResult以及它是如何工作的？

Question

我想知道是否有可能在onActivityResult()Fragment中使用,如果是,那么它是如何工作的,请举例说明.

Answer 1

你会打电话:

startActivityForResult(i, 1);

然后:

@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.
}

Answer 2

是的，您可以OnActivityResult在 Fragment.like 内部使用

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
//super.onActivityResult(requestCode, resultCode, intent);
// perform your action here
}

在活动中使用此代码。

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);
    Fragment fragment = (Fragment) getSupportFragmentManager().findFragmentByTag(childTag);
    if (fragment != null) {
        fragment.onActivityResult(requestCode, resultCode, intent);
    }
}
