Question

您好我搜索了＃34; onActivityResult（）未调用＆＃34;但是在花了好几天后我无法打电话给活动结果。

我在做什么：我从活动中调用片段然后在片段上我从gallary获取图像并且它没有调用片段的onActivityResult。

请建议我如何解决这个问题。

活动类

myswitch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if(isChecked)
{

FragmentTransaction fragmentTransaction=getFragmentManager().beginTransaction();
CarPoolingSignUpFragment carPoolingSignUpFragment=new CarPoolingSignUpFragment();
fragmentTransaction.replace(R.id.carPoolingLoginFrameLayout,carPoolingSignUpFragment,"SignUp");
fragmentTransaction.commit();

}}

从片段中打开gallary

ignUpProPic.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {

Log.d("daf", "ddddddd");
Intent i = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

try {
startActivityForResult(i, RESULT_LOAD_IMAGE);
}catch (ActivityNotFoundException e){
e.printStackTrace();
Toast.makeText(getActivity(), "errrorr", Toast.LENGTH_SHORT).show();
}

片段中的onActivityResult

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

Log.d("ActivityResult", "---");
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {

Uri selectedImage = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};

Cursor cursor = getActivity().getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();

int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
driverProPath = cursor.getString(columnIndex);

signUpProPic.setImageBitmap(BitmapFactory.decodeFile(driverProPath));}}

您需要在fragment onActivityResult内拨打Activity onActivityResult。例如：

我的活动中的代码

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

从活动调用片段时，未在片段中调用OnActivityResult（）方法
