Android ZXING barcodescan put result value in string - java

I am trying to get the result value in a string after there has been scanned.
but it wont work.
I already figured out how to put it in a toast(maketext) that works but a string I cant figure it out.
here's the code please help me.

});
}
#Override
public void onPermissionsGranted(int requestCode) {
//Do anything when permisson granted
Toast.makeText(getApplicationContext(), "Toegang geaccepteerd", Toast.LENGTH_LONG).show();
}
}

remove the String declaration and instead move it as a class member
public void handleResult(Result result) {
//String resultCode = result.getText();
resultCode = result.getText();
like:
myClass extends Activity... {
String resultCode;
}
now you can assign the result code in the hadnleResult callback and use it in the same activity whenever you need it!
Edit:
you have an inner class, i would get rid of that and directly implement the ZXingScannerView.ResultHandler interface:
example:
public class MainActivity extends AbsRuntimePermission implements ZXingScannerView.ResultHandler{
private String resultCode;
private Button getBtn;
private TextView result;
private OkHttpClient client;
boolean doubleTap = false;
private ZXingScannerView scannerView;
private static final int REQUEST_PERMISSION = 10;
Toolbar toolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
result = (TextView) findViewById(R.id.result);
getBtn = (Button) findViewById(R.id.getBtn);
getBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
getWebService();
}
});
client = new OkHttpClient();
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
requestAppPermissions(new String[]{
Manifest.permission.CAMERA},
R.string.msg, REQUEST_PERMISSION);
}
#Override
public void onBackPressed() {
if (doubleTap) {
super.onBackPressed();
} else {
Toast.makeText(this, "Druk Terug opnieuw om de app te sluiten", Toast.LENGTH_SHORT).show();
doubleTap = true;
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
doubleTap = false;
}
}, 500);
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
toolbar = (Toolbar) findViewById(R.id.toolbar);
if (id == R.id.action_settings) {
startActivity(new Intent(this, SettingsActivity.class));
return true;
}
return super.onOptionsItemSelected(item);
}
public void browser1(View view) {
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.suppliance.nl/"));
startActivity(browserIntent);
}
public void scanCode(View view) {
scannerView = new ZXingScannerView(this);
//scannerView.setResultHandler(new ZxingScannerResultHandler());
scannerView.setResultHandler(this);
setContentView(scannerView);
scannerView.startCamera();
}
//class ZxingScannerResultHandler implements ZXingScannerView.ResultHandler {
#Override

// String resultCode = result.getText();

I will go with this or something similar, depending on how you are handling the scanner view
public class MainActivity extends AppCompatActivity
implements ZXingScannerView.ResultHandler {
private ZXingScannerView mScannerView;
private String resultCode;
#Override
public void onCreate(Bundle state) {
super.onCreate(state);
mScannerView = new ZXingScannerView(this); // Programmatically initialize the scanner view
setContentView(mScannerView); // Set the scanner view as the content view
}
#Override
public void onResume() {
super.onResume();
mScannerView.setResultHandler(this); // Register ourselves as a handler for scan results.
mScannerView.startCamera(); // Start camera on resume
}
#Override
public void onPause() {
super.onPause();
mScannerView.stopCamera(); // Stop camera on pause
}
#Override
public void handleResult(Result rawResult) {
resultCode = rawResult.getText();
//now use resultCode
}
}

You can create your own interface :
private interface OnListItemClickListener
{
void onListItemClicked(View view, int position);
}
Then use it in your adapter class this way:
class CustomAdapter extends BaseAdapter {
//create an instance
private OnListItemClickListener onListItemClickListener;
//define the object setter
void setOnListItemClickListener(OnListItemClickListener listener)
{
this.onListItemClickListener=listener;}
#Override
public int getCount() {
return comments_dateList.size();
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public boolean isEnabled(int position) {
return false;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
convertView = getLayoutInflater().inflate(R.layout.customlayout_lastcomment_homepage, null);
TextView textViewUser = (TextView) convertView.findViewById(R.id.textViewUser);
TextView textViewDate = (TextView) convertView.findViewById(R.id.textViewDate);
TextView textViewMessage = (TextView) convertView.findViewById(R.id.textViewMessage);
textViewUser.setText(comments_userList.get(position));
textViewDate.setText(comments_dateList.get(position));
textViewMessage.setText(comments_messageList.get(position));
//Then here trigger
convertView.setOnClickListener(new View.OnClickListener()
{
#override
void onClick(View v)
{
onListItemClickListener.onListItemClicked(v,position);
//you may be asked to set position as final
}
});
return convertView;
}
}
Then in your onCreate method where you attached the adapter, set the listener to your adapter:
MainActivity.CustomAdapter customAdapter = new MainActivity.CustomAdapter();
customAdapter.setOnListItemClickListener(new OnListItemClickListener()
{
#override
void onListItemClicked(View view,int position)
{
//then here place your desired action
}
});
lastComments.setAdapter(customAdapter);
I hope this may be helpful. You can still ask for clarifications in comment

Swipe to refresh webview fragment doesnt load url

I have a webview fragment in my MainActivity. I am trying to add Swipetoview inside it. But when I load the fragment it doesn't load the url.
My fragment:
// Inflate the layout for this fragment
View vDriver=inflater.inflate(R.layout.fragment_drivers, container, false);
mWebView = vDriver.findViewById(R.id.drivers_webview);
mWebView.loadUrl("https://ahmetbarpa-grand-prix.firebaseapp.com/drivers.html");
// Enable Javascript
//WebSettings webSettings = mWebView.getSettings();
//webSettings.setJavaScriptEnabled(true);
// Force links and redirects to open in the WebView instead of in a browser
mWebView.setWebViewClient(new WebViewClient());
swipeLayout = vDriver.findViewById(R.id.fragment_drivers);
swipeLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
mWebView.reload();
new Handler().postDelayed(new Runnable() {
#Override public void run() {
swipeLayout.setRefreshing(false);
}
}, 5000);
}
});
return vDriver;
My fragment layout:
<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/fragment_drivers"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".Drivers">
<WebView
android:id="#+id/drivers_webview"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</android.support.v4.widget.SwipeRefreshLayout>
I tried different things and this is the last code I tried. What am I doing wrong?
Thanks for your time in advance.

Instead of reload()
mWebView.loadUrl("https://ahmetbarpa-grand-prix.firebaseapp.com/drivers.html");
Try it..
If this is not the way you want, the second method is:
make a new class as:
private class MyBrowser extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
then, Instead of this:
mWebView.setWebViewClient(new WebViewClient());
write this:
mWebView.setWebViewClient(new MyBrowser());
Hopefully your problem will be solved

Here is the error:
Please help me to understand & solve this error

You need to unbind service:
#Override
protected void onStop() {
// your onStop code
if(musicConnection != null) {
unbindService(musicConnection);
}
super.onStop();
}

Saving state while rotation

I Have an app in which the main activity shows a question and has true button false button and cheat button
When user press the correct option, listener will Toast Correct.. and otherwise listener will Toast Incorrect
Now when we press the cheat button new activity is launched and has a textview "Are you sure you want to cheat?", another textview which is blank and a show answer button..
When user presses the show answer button , the blank text view is set to the answer of the question (as asked in the main activity)
And when the user goes back the true and false button onClickListeners are now set to make a toast "Cheating is wrong"
i have declared a boolean value which is set to false, the boolean value is set to True and i save it in the bundle so that when the user rotates the screen , the value of the variable is not overwritten on onCreate(..) method being recalled..
I tried debugging with break points in eclipse , the value is not overridden still on main activity "Cheating is wrong" doesnt show up , it shows Correct or Incorrect..
