How to use camera from a fragment and display captured image in an imageview on the same fragment?

I want to display a captured image in my fragment but it is not showing, e.g. though the callback code in the fragment appears to be running.
Here's my Activity -
public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
// Views and Context
private View nav_header_view;
private Context context;
// Widgets
private TextView tvCompanyName, tvCompanyEmail, tvName;

Here's my Manifest -

<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-feature android:name="android.hardware.camera" android:required="true"/>
When I clicked the Camera intent in the fragment, the imageview in my fragment wouldn't change. I don't know why is this happening because it works perfectly fine in an activity.

In Activity.onResume () you end up calling openAccountFragment (). This creates a new fragment and is run every time the screen becomes visible.(By the way a possibly unrelated bug is that you are not calling newInstance() here.)
Each time you create a new fragment, the old one is removed.
But your call back function is happening on the old fragment, which is no longer attached or therefore visible (note this ties in with Mike's comments)
The solution is to not replace the existing fragment with a new one if you already have the right type.

override onActivityResult into MainActivity. make imageView public and access imageView into activity result method as follow.
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == Activity.RESULT_OK) {
Fragment f = getSupportFragmentManager().findFragmentById(R.id.content_main);
if (f instanceof AccountFragment) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
f.imageView.setImageBitmap(photo);
}
}
}

My form fragment is child fragment. And this parent fragment where I implement backaction.
#Override
public void onResume() {
super.onResume();
getView().setFocusableInTouchMode(true);
getView().requestFocus();
getView().setOnKeyListener(new View.OnKeyListener() {
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_UP && keyCode == KeyEvent.KEYCODE_BACK) {
backAction();
return true;
}
return false;
}
});
}
public void backAction() {
if (getChildFragmentManager().getBackStackEntryCount() > 0) {
getChildFragmentManager().popBackStack();
}
else {
((MainActivity) getActivity()).setCurrentItem(0, true);
}
}

Create TextWatcher like
TextWatcher textWatcher=new TextWatcher() {
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
//TODO Auto-generated method stub
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
#Override
public void afterTextChanged(Editable s) {
if(!s.toString().contains("+7 ")){
edt_phone.setText("+7 ");
Selection.setSelection(edt_phone.getText(), edt_phone.getText().length());
}
};
Add it to edt_phone like
edt_phone.addTextChangedListener(textWatcher);
Then in the back press event remove the listener,
getView().setOnKeyListener(new OnKeyListener() {
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
edt_phone.removeTextChangedListener(textWatcher);
return true;
}
}
return false;
}
});

In your foam fragment(child fragment)
Communicator communicator;
#Override
public void onBackPressed() {
super.onBackPressed();
communicator.exitFragment();
}
public void setCommunicator(Communicator communicator)
{
this.communicator = communicator;
}
public interface Communicator
{
void exitFragment();
}
in your parent fragment do this
public parentFragment extends Fragment implements childFragment.Communicator
{
#override
public void onCreatView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
childFragment.setCommunicator(this);
}
public void exitFragment()
{
getActivity().finish();
}
}

Fragments are managed by the Fragment Managers which are called by the Activity; so, to control what you want to do when the back button is clicked, you must do that in the activity;
Now, if you have more than one fragment set, you should use tags to find them, check to see if they are visible and if so, do what you mentioned above.
When setting your fragments, you should give them a tag and then use this tag later to findFragmentByTagName() and do an if check to see which fragment is set at the moment;
Let me know if you need any clarification on the same.

Google sign in fragment , android?

Using android studio
I am trying to sign in from a fragment
Activity Code:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if(savedInstanceState==null)
{
Fragment fragment = null;
fragment=new LoginFragment();
if (fragment != null) {
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.frame_container, fragment).commit();
// update selected item and title, then close the drawer
} else {
// error in creating fragment
Log.e("MainActivity", "Error in creating fragment");
}
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == LoginFragment.RC_SIGN_IN) {
LoginFragment fragment = (LoginFragment) getFragmentManager()
.findFragmentById(R.id.frameLayoutLogin);
fragment.onActivityResult(requestCode, resultCode, data);
} else {
super.onActivityResult(requestCode, resultCode, data);
}

What is the issue here? Any help?

Add this after your mGoogleApiClient initiated
Intent intent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(intent, requestCode);
