我想startActivityResult()但onActivityResult()未被调用...
在我的片段中：
ivAvatar.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
ChangeAvatar.onClickAvatar(getActivity(), ivAvatar);
pathAvatar = ChangeAvatar.getPathAvatar();
}
});
在我的班级ChangeAvatar.java中：
public class ChangeAvatar {
public static FragmentActivity activity;
private static Uri mCapturedImageURI;
private static ImageView ivAvatar;
private static String pathAvatar;
private static final int CAPTURE_PICTURE = 0;
private static final int SELECT_PICTURE = 1;
private static final int SELECT_PICTURE_GOOGLE = 2;
public ChangeAvatar () {
}
public static void onClickAvatar(FragmentActivity a, ImageView iv) {
ivAvatar = iv;
activity = a;
final CharSequence[] items = { "Prendre une photo", "Choisir une image", "Annuler" };
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(activity);
// set title
alertDialogBuilder.setTitle("Avatar :");
// set dialog message
alertDialogBuilder.setCancelable(false).setItems(items, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int item) {
if (item == 0) {
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, "");
mCapturedImageURI = activity.getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mCapturedImageURI);
intent.putExtra("crop", "true");
intent.putExtra("aspectX", 170);
intent.putExtra("aspectY", 170);
intent.putExtra("outputX", 5000);
intent.putExtra("outputY", 5000);
activity.startActivityForResult(Intent.createChooser(intent, "Appareil photo"), CAPTURE_PICTURE);
}
if (item == 1) {
Intent intent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI);
intent.setType("image/*");
activity.startActivityForResult(Intent.createChooser(intent, "Choisir une application"),
SELECT_PICTURE);
}
if (item == 2) {
dialog.cancel();
}
}
});
// create alert dialog
AlertDialog alertDialog = alertDialogBuilder.create();
// afficher
alertDialogBuilder.show();
}

您的onActivityResult()应该位于FragmentActivity中，因为您只是从该类调用startActivityResult()。

onActivityResult（）仅适用于Activity Class。首先，在onCreate（）之后使用onActivityResult（）之后扩展Activity。
