I use XZing 3.6.0 to scan QR codes within my Android app.
MainActivity.java

AndroidManifest.xml
<activity

It works... except the camera is shown in landscape mode. How to change that to portrait mode?
Add this to your Manifest File :
<activity
android:name="com.journeyapps.barcodescanner.CaptureActivity"
android:screenOrientation="portrait"
tools:replace="android:screenOrientation"
android:stateNotNeeded="true"/>
try this in XML file :
<com.journeyapps.barcodescanner.CompoundBarcodeView
android:id="#+id/barcode_scanner"
android:layout_width="match_parent"
android:layout_height="0dp"
app:zxing_viewfinder_mask="#ffffff"
android:layout_weight="40"
>
</com.journeyapps.barcodescanner.CompoundBarcodeView>
and here is the fragment code :
public class ScanFragment extends Fragment {
private String toast;
private LinearLayout qrCameraLayout;
IntentIntegrator intentIntegrator;
private CompoundBarcodeView barcodeView;
private TextView tv_qr_print;
public ScanFragment() {

In my file Reservation.java I have a function that loads LieuActivity.
So this is the function
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.TextView;
public class Reservation extends AppCompatActivity implements View.OnClickListener {
private Button end,deb,lieu,type,cherch;
private TextView type_v ;
private ImageView car;
private View division;
private ListView list;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_reservation);
end = (Button)findViewById( R.id.btn_fin );
end.setOnClickListener( this);
deb= (Button)findViewById( R.id.deb_btn);
deb.setOnClickListener( this );
lieu = (Button)findViewById( R.id.btn_local);
lieu.setOnClickListener( this );
type = (Button)findViewById( R.id.btn_type);
type.setOnClickListener( this );
cherch= (Button)findViewById( R.id.btn_cherch);
cherch.setOnClickListener( this );
division= (View)findViewById( R.id.div3);
type_v= (TextView)findViewById( R.id.type);
car= (ImageView) findViewById( R.id.pic_car);
list=(ListView)findViewById(R.id.fin_list);
ArrayAdapter<String> mAdapter= new ArrayAdapter<String>(Reservation.this, android.R.layout.simple_list_item_1, getResources().getStringArray(R.array.values));
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (position == 3 )
{
Intent i = new Intent(view.getContext(),Deb_FinActivity.class);
startActivityForResult(i,3);
}
}
});
list.setAdapter(mAdapter);
}
#Override
public void onClick(View view) {
switch(view.getId())
{
case R.id.deb_btn:
loadDebActivity();
break;
case R.id.btn_fin:
loadFin();
break;
case R.id.btn_local:
loadLieuActivity();
break;
case R.id.btn_type:
loadTypeActivity();
break;
case R.id.btn_cherch:
loadSearch();
break;
}
}
private void loadDebActivity()
{
startActivity(new Intent( this,Deb_FinActivity.class ) );
finish();
}
private void loadFin()
{
lieu.setVisibility( View.INVISIBLE );
type.setVisibility(View.INVISIBLE);
cherch.setVisibility(View.INVISIBLE);
car.setVisibility(View.INVISIBLE);
division.setVisibility(View.INVISIBLE);
type_v.setVisibility(View.INVISIBLE);
list.setVisibility(View.VISIBLE);
}
private void loadLieuActivity()
{
startActivity(new Intent( this,LieuActivity.class ) );
lieu.setText(getIntent().getStringExtra("mytext"));
}
private void loadTypeActivity()
{
startActivity(new Intent( this,TypeActivity.class ) );
finish();
}
private void loadSearch()
{
}
}
In my LieuActivity.java I have this code
public class LieuActivity extends AppCompatActivity {
private EditText lieuu;
private TextView local;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_lieu);
addListenerOnButton();
}
public void addListenerOnButton() {
local = (TextView) findViewById(R.id.position);
local.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
EditText lieuu = (EditText)findViewById(R.id.local);
String text =lieuu.getText().toString();
Intent myIntent = new Intent(view.getContext(),Reservation.class);
myIntent.putExtra("mytext",text);
startActivity(myIntent);
}
});
}
}
The problem is when I edit in my LieuActivity and go back to reservation it does not return the extra value until I click another time on the editText so I see the updated data for a second before re-going to LieuActivity and modify it another time .
Put these lines in onCreate() of Reservation activity
String text = getIntent().getStringExtra("mytext");
if (text != null) {
lieu.setText(text);
}
and make this change:
private void loadLieuActivity()
{
startActivity(new Intent( this,LieuActivity.class ) );
finish();
}
Do this in oncreate of Reservation
Bundle extras = getIntent().getExtras();
String string;
if (extras != null) {
string = extras.getString("mytext");
lieu.setText(string);
}
Make changes like this in LieuActivity :-
public class LieuActivity extends AppCompatActivity {
private EditText lieuu;
private TextView local;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_lieu);
addListenerOnButton();
}
public void addListenerOnButton() {
local = (TextView) findViewById(R.id.position);
local.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
EditText lieuu = (EditText)findViewById(R.id.local);
String text =lieuu.getText().toString();
Intent myIntent = new Intent(view.getContext(),Reservation.class);
myIntent.putExtra("mytext",text);
setResult(RESULT_OK, myIntent );
});
}
}
In Reservation put onActivityResult()

Hope this may help you
I added up button to tool bar to navigate from fragment B to fragment A.
When I click up button, I couldn't restore the member variables of A fragment
Because savedInstanceState was null even though I Overrided
onSaveInstanceState(Bundle) and put all the variables which I wanted to restore later.
I did my best to search the reason, but I couldn't find the reason and the solutoin.
There were differeces between my situation and questions(answers) of other posts.
First, my fragment is hosted dynamically, so I couldn't give an id to my fragment in XML or something.
Second, it works when I rotate my device(savedInstanceState is not null on onCreateView()). I thought both(to rotate the device and to navigate from fragment B to fragment A) is the same situation
in that the fragment A is destroyed and recreated so onSaveInstanceState method
is called first and onCreateView is called after fragment A is recreated.
I have no idea why such situation occured. Please help me. Thanks.

Because the Activity created after onCreateView .
You can use onActivityCreated method to restore the fragment's state here .
#Override
public void onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
if (savedInstanceState != null) {
mSubtitleVisible = savedInstanceState.getBoolean(SAVED_SUBTITLE_VISIBLE);
}
Log.e("TAG", "onActivityCreated OK");
Log.e("TAG", savedInstanceState.getBoolean(SAVED_SUBTITLE_VISIBLE) + "");
}
Edit
Change to onViewStateRestored method,and try again .
Add log in onSaveInstanceState and onViewStateRestored ,make sure all of them work .
#Override
public void onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
if (savedInstanceState != null) {
mSubtitleVisible = savedInstanceState.getBoolean(SAVED_SUBTITLE_VISIBLE);
}
Log.e("TAG", "onActivityCreated OK");
Log.e("TAG", "onActivityCreated " + savedInstanceState.getBoolean(SAVED_SUBTITLE_VISIBLE));
}
#Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putBoolean(SAVED_SUBTITLE_VISIBLE, mSubtitleVisible);
Log.e("TAG", "onSaveInstanceState OK");
Log.e("TAG", "onSaveInstanceState" + mSubtitleVisible);
}
Edit
You can save the status in onSaveInstanceState and onDestroyView.
Then,restore the state in onActivityCreated
You can do like this.
Bundle savedState;
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
// Restore State Here
if (!restoreStateFromArguments()) {
// First Time, Initialize something here
onFirstTimeLaunched();
}
}
protected void onFirstTimeLaunched() {
}
#Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
// Save State Here
saveStateToArguments();
}
#Override
public void onDestroyView() {
super.onDestroyView();
// Save State Here
saveStateToArguments();
}
private void saveStateToArguments() {
if (getView() != null)
savedState = saveState();
if (savedState != null) {
Bundle b = getArguments();
b.putBundle("savedState", savedState);
}
}
private boolean restoreStateFromArguments() {
Bundle b = getArguments();
savedState = b.getBundle("savedState");
if (savedState != null) {
restoreState();
return true;
}
return false;
}
// Restore Instance State Here
private void restoreState() {
if (savedState != null) {
// For Example
uSelected.setText(savedState.getString("uSelected"));
onRestoreState(savedState);
}
}
protected void onRestoreState(Bundle savedInstanceState) {
}
// Save Instance State Here
private Bundle saveState() {
Bundle state = new Bundle();
// For Example
state.putString("uSelected", uSelected.getText().toString());
onSaveState(state);
return state;
}

it is my xml file why i am not able to get the fragment with my facebook login button.
please any one can explain me.
Create a FragmentActivity and add your fragment to that FragmentActivity
public class MainActivity extends FragmentActivity{
FacebokkFragment fbFragment;
ArrayList<Fragment> fragemetnList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
fbFragment = new FacebokkFragment();
fragemetnList = getFragmnetsList();
setContentView(R.layout.activity_main);
}
ArrayList<Fragment> getFragmnetsList() {
ArrayList<Fragment> fragments = new ArrayList<Fragment>();
fragments.add(fbFragment);
// you can also add more fragments here
return fragments;
}
}
Now create an activity_main.xml file into your res/layout directory
Don't forget to make the entry of your MainActivity into AndroidManifest.xml file
May this code will solve your problem
if (rootView != null) {
ViewGroup parent = (ViewGroup) rootView.getParent();
if (parent != null) {
parent.removeView(rootView);
}
}
Is this part of code really required? Try removing this.
Try this
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_facebook, container, false);
...
return rootView;

this is what you need to do in order to ristrict that.
dialog.setCanceledOnTouchOutside(false);
this will make sure dialog is not dismissed when touched outside of dialog box area.
I'm having some issue with zxing onActivityResult().
As you can see in the code I did properly invoke new intent as described in https://code.google.com/p/zxing/wiki/ScanningViaIntent.
The question is how can I catch onActivityResult() in Fragment, since I need this data in my Fragmnet and not in Activity?
package com.example.testingcodereading;
import android.content.Intent;
import android.content.pm.ActivityInfo;
import android.content.pm.ResolveInfo;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
public class MainFragment extends Fragment {
private Button mButtonXZing;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState){
View v = inflater.inflate(R.layout.fragment_main, parent, false);
mButtonXZing = (Button) v.findViewById(R.id.button_xzing);
mButtonXZing.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
IntentIntegrator integrator = new IntentIntegrator(getActivity());
integrator.initiateScan();
}
});
return v;
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
System.out.println("never here");
IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
if (scanResult != null) {
// handle scan result
}
// else continue with any other code you need in the method
}
}
public class MainActivity extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FragmentManager fm = getSupportFragmentManager();
Fragment f = fm.findFragmentById(R.id.fragmentContainer);
if(f == null){
f = new MainFragment();
fm.beginTransaction()
.add(R.id.fragmentContainer, f)
.commit();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
System.out.println("the code is catch");
}
}
As Martynnw pointed out the issue is to call fragment.startActivityForResult instead of activity.startActivityForResult. So just use next wrapper:
import android.content.Intent;
import android.support.v4.app.Fragment;
import com.google.zxing.integration.android.IntentIntegrator;
public final class FragmentIntentIntegrator extends IntentIntegrator {
private final Fragment fragment;
public FragmentIntentIntegrator(Fragment fragment) {
super(fragment.getActivity());
this.fragment = fragment;
}
#Override
protected void startActivityForResult(Intent intent, int code) {
fragment.startActivityForResult(intent, code);
}
}
integrator.initiateScan();
Change the above line as
integrator.forSupportFragment(fragment_name.this).initiateScan();
Alternative ZXing Android Embedded, implementation:
import com.google.zxing.integration.android.IntentIntegrator;
import com.google.zxing.integration.android.IntentResult;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
new IntentIntegrator(this).initiateScan(); // `this` is the current Activity
}
Use from a Fragment:
IntentIntegrator.forFragment(this).initiateScan(); // `this` is the current Fragment
// If you're using the support library, use:
// IntentIntegrator.forSupportFragment(this) instead.
Get the results:
#Override
public void onActivityResult(int requestCode, int resultCode,Intent data) {
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if(result != null) {
if(result.getContents() == null) {
Toast.makeText(this, "Cancelled", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(this, "Scanned: " + result.getContents(), Toast.LENGTH_LONG).show();
}
} else {
super.onActivityResult(requestCode, resultCode, data);
}
}

I had this problem and resolved it with below codes:
IntentIntegrator integrator = new IntentIntegrator(getActivity());
integrator.forSupportFragment(MyFragment.this).initiateScan();
Shall call the scan in this way:
IntentIntegrator.forSupportFragment(YourFragment.this)
.setDesiredBarcodeFormats(IntentIntegrator.QR_CODE)
.setBeepEnabled(true/false)
.setPrompt("blahblahblah")
.initiateScan();
Then you can get the scan result in Fragment's onActivityResult
Make sure OnActivityResult in your Activity is calling super.OnActivityResult(). That should ensure it's called on the Fragment as well.
Alternatively, you could modify the IntentIntegrator code so it calls StartActivityResult on the Fragment, either by passing the fragment to the constructor, or passing it to initiateScan.
Try creating IntentIntegrator object in Fragment as below.
val scanIntegrator = IntentIntegrator.forSupportFragment(this#HomeFragment)
scanIntegrator.setPrompt("Scan")
scanIntegrator.setBeepEnabled(true)
//The following line if you want QR code
scanIntegrator.setDesiredBarcodeFormats(IntentIntegrator.QR_CODE_TYPES)
scanIntegrator.captureActivity = CaptureActivityAnyOrientation::class.java
scanIntegrator.setOrientationLocked(true)
scanIntegrator.setBarcodeImageEnabled(true)
scanIntegrator.initiateScan()
public void scanCode() {
IntentIntegrator.forSupportFragment(this).
setCaptureActivity(CaptureAct.class).
setOrientationLocked(false)
.setDesiredBarcodeFormats(IntentIntegrator.PRODUCT_CODE_TYPES)
.setPrompt("Scanning code")
.initiateScan();
}
A solution : A basic example of how you can manage it
Main Activity
public static int tapTrick = 0;
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
//super.onActivityResult(requestCode, resultCode, data);
if(tapTrick!=0 && tapTrick==1) {
Tab1.onActivityResult(requestCode, resultCode, data, MainActivity.this);
}else if (tapTrick!=0 && tapTrick==2){
//Tab2.onActivityResult(requestCode, resultCode, data, MainActivity.this);
}
}
Fragment 1
MainActivity.tapTrick=1; // onCreateView or onClick (load images/files)
public static void onActivityResult(int requestCode, int resultCode, Intent intent, Context context) {
}
Fragment 2
MainActivity.tapTrick=2;
public static void onActivityResult(int requestCode, int resultCode, Intent intent, Context context) {
}
Fragment x
MainActivity.tapTrick=x;
public static void onActivityResult(int requestCode, int resultCode, Intent intent, Context context) {
}
