【问题描述】：
我在 Fragment 中工作，我需要从中选择一个图像 图库并将其设置为 imageView 但 getActivity().startActivityForResult() 现在可以工作了
我已经检查了很多链接，但都说调用这个 父活动中的方法，但我没有任何父活动 片段在另一个片段中。我也检查了这个链接
startActivityForResult is not working in Fragment
这是我的代码：-
MainActivity 类：-
public class SabaKuchHomeActivity extends FragmentActivity {

private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
// nav drawer title
private CharSequence mDrawerTitle;
// used to store app title

@SuppressLint("NewApi")
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.home_activity);
mTitle = mDrawerTitle = getTitle();
// load slide menu items
navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);
// nav drawer icons from resources
navMenuIcons = getResources()
.obtainTypedArray(R.array.nav_drawer_icons);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.list_slidermenu);
// adding nav drawer items to array
// Home
navDrawerItems.add(new NavDrawerItem(navMenuTitles[0], navMenuIcons.getResourceId(0, -1)));
// Find People
navDrawerItems.add(new NavDrawerItem(navMenuTitles[1], navMenuIcons.getResourceId(1, -1)));
// Photos
navDrawerItems.add(new NavDrawerItem(navMenuTitles[2], navMenuIcons.getResourceId(2, -1)));
// Communities, Will add a counter here
navDrawerItems.add(new NavDrawerItem(navMenuTitles[3], navMenuIcons.getResourceId(3, -1), true, "22"));
// Pages
navDrawerItems.add(new NavDrawerItem(navMenuTitles[4], navMenuIcons.getResourceId(4, -1)));
// What's hot, We will add a counter here
navDrawerItems.add(new NavDrawerItem(navMenuTitles[5], navMenuIcons.getResourceId(5, -1), true, "50+"));
navDrawerItems.add(new NavDrawerItem(navMenuTitles[6], navMenuIcons.getResourceId(6, -1)));
// Recycle the typed array
navMenuIcons.recycle();
mDrawerList.setOnItemClickListener(new SlideMenuClickListener());
// setting the nav drawer list adapter
adapter = new NavDrawerListAdapter(getApplicationContext(),
navDrawerItems);
mDrawerList.setAdapter(adapter);
// enabling action bar app icon and behaving it as toggle button

这里是
ProfileSettingFragment()片段：-
@SuppressLint("NewApi")

return rootView;
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
}
private class MyPageAdapter extends FragmentStatePagerAdapter
{
private List<android.support.v4.app.Fragment> fragments;
public MyPageAdapter(FragmentManager fm) {
super(fm);
// TODO Auto-generated constructor stub
this.fragments=new ArrayList<android.support.v4.app.Fragment>();
fragments.add(new ProfileGeneralSetting());

}
@Override

// TODO Auto-generated method stub
}
}
这是我必须更改图像的嵌套片段：-
public class ProfileOzoneSetting extends Fragment implements MiFeelingBase, OnClickListener{
NetworkImageView genSetOzoneUserImage;
private ArrayList<String>arrCategoryId=new ArrayList<String>();
List<String> interestList = new ArrayList<String>();
String[] interest;
Boolean setImg ;
private static final int SELECT_PICTURE = 1;
private String selectedImagePath;
Button SettingOzSave;
private MultipartEntity reqEntity;
String[] y ={""};
private String strUserID;
ImageLoader imageLoader = AppContoller.getInstance().getImageLoader();
OzoneSettingData ozSettingList = new OzoneSettingData();
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
// TODO Auto-generated method stub
View rootView = inflater.inflate(R.layout.profiesettingozone, container, false);
genSetOzoneUserImage = (NetworkImageView)rootView.findViewById(R.id.genSetOzoneUserImage);
SettingOzSave = (Button)rootView.findViewById(R.id.SettingOzSave);
SettingOzSave.setOnClickListener(this);
genSetOzoneUserImage.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Log.d("first time", "before method");
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
//startActivityForResult(Intent.createChooser(intent,"Select Picture"), SELECT_PICTURE);
Log.d("first time", "before method11");
//startActivityForResult(intent, SELECT_PICTURE);
getParentFragment().startActivityForResult(intent, SELECT_PICTURE);
//startActivityForResult(intent, SELECT_PICTURE);
//((SabaKuchHomeActivity)getActivity()).startActivitForResult(intent, SELECT_PICTURE);
//getContext().getApplicationContext.startActivityforResult(intent, SELECT_PICTURE);
//fragment.getApplicationContext.startActivityforResult(intent, SELECT_PICTURE);
//getActivity().startActivityForResult(intent, SELECT_PICTURE);
//startActivityForResult(intent, SELECT_PICTURE);
//((SabaKuchHomeActivity)getActivity()).startActivitForResult(intent, SELECT_PICTURE);
Log.d("first time", "before method22");
}
});
APIAccess.fetchData(ProfileOzoneSetting.this, getActivity(), getActivity());
return rootView;
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.d("first time", "before method33");
super.onActivityResult(requestCode, resultCode, data);
Log.d("first time", "before method44");
if (requestCode == SELECT_PICTURE && resultCode ==Activity.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]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
genSetOzoneUserImage.setImageBitmap(BitmapFactory.decodeFile(picturePath));
setImg = true;
}
}
@Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
AppContoller.getInstance().pref=getActivity().getSharedPreferences(AppContoller.getInstance().PREF_NAME, 0);
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = getActivity().managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
请让我知道我在这里犯了什么错误？？？
更新
我确实更新了SabaKuchHomeActivity 和ProfileSettingFragment
【问题讨论】：
-
只需在 Log onClick of your button 中打印一些内容
-
尝试将您的
getActivity()投射到父活动中。例如((YourActivityClasss)getActivity()).startActivitForResult(); -
看@vilpe89的回答
-
@Devraj 甚至父片段也来自您调用的位置。它应该是 Activity 或 Fragment Activity.There 覆盖 OnActvityResult
-
@Elltz 是的，当然......即使我也在尝试这样做，但因为我做了这么多编码而感到困惑，现在我的大脑被阻塞了...... lolzz.. 请给我一些演示.这将非常有帮助。 :)
