How to open WebView when click on Card View

How to open WebView when click on Card View - android

I trying to open WebView when I click on Card View. The WebView is implemented in Main Activity. It is not working. I am new in coding. This is the Dashboard Activity 👇. Please tell me how can I solve the problem.
public class DashBoardActivity extends MainActivity implements View.OnClickListener {
public CardView card1, card2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate( savedInstanceState );
setContentView( activity_dashboard );
card1 = findViewById( R.id.c1 );
card2 = findViewById( R.id.c2 );
card1.setOnClickListener( this );
card2.setOnClickListener( this );
}
#Override
public void onClick(View v) {
int id = v.getId();
if (id == R.id.nav_home1) {
web_view( "example1.com" );
} else if (id == R.id.nav_home2) {
web_view( "example2.com");
}
}
}

You don't need to extend your Main Activity.
Just pass the URL in Intent Extras to your Main Activity and start it there.
#Override
public void onClick(View v) {
Intent intent = new Intent(this, MainActivity.class);
String example1 = "example1.com";
String example2="example2.com";
int id = v.getId();
if (id == R.id.nav_home1) {
intent.putExtra("URL", example1);
} else if (id == R.id.nav_home2) {
intent.putExtra("URL", example2);
}
startActivity(intent);
}
Then retrieve these extras in your onCreate MainActivity
private WebView wv1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String url;
if (savedInstanceState == null) {
Bundle extras = getIntent().getExtras();
if(extras == null) {
url= null;
} else {
url= extras.getString("URL");
}
} else {
url= (String) savedInstanceState.getSerializable("URL");
}
wv1=(WebView)findViewById(R.id.webView);
wv1.setWebViewClient(new MyBrowser());
wv1.getSettings().setLoadsImagesAutomatically(true);
wv1.getSettings().setJavaScriptEnabled(true);
wv1.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
wv1.loadUrl(url);
}

How to move from activity to fragment

I wrote this code for login and for chatting;
login is an activity where is chatting is a fragment; here is my activity :
public class Consultant extends AppCompatActivity {
private FirebaseAuth auth;
private Button loginbtn;
private EditText email;
private EditText pass;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_consultant);
auth = FirebaseAuth.getInstance();
loginbtn = (Button) findViewById(R.id.loginbtn);
email = (EditText) findViewById(R.id.email);
pass = (EditText) findViewById(R.id.pass);
loginbtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
checkEmailandpassword();
}
});
}
public boolean checkEmailandpassword() {
if (validate()) {
String CEmail = email.getText().toString().trim();
String CPass = pass.getText().toString().trim();
auth.signInWithEmailAndPassword(CEmail, CPass).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
Toast.makeText(Consultant.this, "welcome", Toast.LENGTH_LONG).show();
Intent i = new Intent(Consultant.this,Consultant_Home_Chatting.class);
startActivity(i);
} else {
Toast.makeText(Consultant.this, "wrong ", Toast.LENGTH_LONG).show();
}
}
});
}
return false;
}
private boolean validate() {
boolean result = false;
String CPass = pass.getText().toString();
String CEmail = email.getText().toString();
if (CPass.isEmpty() || CEmail.isEmpty()) {
Toast.makeText(Consultant.this, "all fields required", Toast.LENGTH_LONG).show();
} else {
result = true;
}
return result;
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_nav, menu);
return true;
}
}
and here my fragment :
public class Consultant_Home_Chatting extends Fragment {
private ViewPager mViewP ;
private FirebaseAuth mAuth ;
private TabLayout mTab ;
private TabsPagerAdapter mAdapter ;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_consultant__home__chatting, container, false);
}
public Consultant_Home_Chatting() {
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
mAuth = FirebaseAuth.getInstance();
mViewP = (ViewPager) getView().findViewById(R.id.main_tabs_pager);
mAdapter = new TabsPagerAdapter(getFragmentManager());
mViewP.setAdapter(mAdapter);
mTab = (TabLayout) getView().findViewById(R.id.main_tabs);
mTab.setupWithViewPager(mViewP);
}
I tried to add a new class holding these liens then make a constructor in my fragment and onCreatOptions method in my activity but it does not work!
I think the solution is to use the Bundle but I don't know how to use it or can I use it and what can I send inside put extra, can you please help?
if (savedInstanceState == null){
getFragmentManager().beginTransaction()
.add(android.R.id.content, new Consultant_Home_Chatting ()).commit();}

to use bundle simple create the instance of your fragment and then create bundle add all data you want and add this bundle to the fragment.
Here is example:
In activity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TestFragment testFragment = new TestFragment();
Bundle bundle = new Bundle();
bundle.putString("name", "John");
bundle.putInt("age", 24);
testFragment.setArguments(bundle);
getSupportFragmentManager()
.beginTransaction()
.add(R.id.content, testFragment).commit();
}
In your fragment:
public class TestFragment extends Fragment {
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle bundle = getArguments();
if(bundle != null){
String name = bundle.getString("name");
int age =`enter code here` bundle.getInt("age");
}
}
}

How to open url in webview activity

How to open Url in Webview activity
Hi,
i want to open link in WebView activity right now my code is scan barcode & open link directly to browser but
i want to change it and open in Webview
how can i do this please help me to fix this issue
thanks
here is code of BarcodeScannerActivity
public class BarcodeScannerActivity extends AppCompatActivity {
String scanContent;
String scanFormat;
TextView textView;
Button button;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_barcode_scanner);
textView = (TextView) findViewById(R.id.textView);
button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
IntentIntegrator scanIntegrator = new IntentIntegrator(BarcodeScannerActivity.this);
scanIntegrator.setPrompt("Scan");
scanIntegrator.setBeepEnabled(true);
//enable the following line if you want QR code
//scanIntegrator.setDesiredBarcodeFormats(IntentIntegrator.QR_CODE_TYPES);
scanIntegrator.setCaptureActivity(CaptureActivityAnyOrientation.class);
scanIntegrator.setOrientationLocked(true);
scanIntegrator.setBarcodeImageEnabled(true);
scanIntegrator.initiateScan();
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
IntentResult scanningResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if (scanningResult != null) {
if (scanningResult.getContents() != null) {
scanContent = scanningResult.getContents().toString();
scanFormat = scanningResult.getFormatName().toString();
}
Toast.makeText(this, scanContent + " type:" + scanFormat, Toast.LENGTH_SHORT).show();
textView.setText(scanContent + " type:" + scanFormat);
Intent browseintent=new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.example.com/index.php?iduser="+ scanContent));
startActivity(browseintent);
} else {
Toast.makeText(this, "Nothing scanned", Toast.LENGTH_SHORT).show();
}
}
}
Webview Activity Code
public class SecondActivity extends AppCompatActivity {
Button b1;
EditText ed1;
private WebView wv1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
b1=(Button)findViewById(R.id.button);
ed1=(EditText)findViewById(R.id.editText);
wv1=(WebView)findViewById(R.id.webView);
wv1.setWebViewClient(new MyBrowser());
b1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String url = ed1.getText().toString();
wv1.getSettings().setLoadsImagesAutomatically(true);
wv1.getSettings().setJavaScriptEnabled(true);
wv1.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
wv1.loadUrl(url);
}
});
}
private class MyBrowser extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
}

Replace the following code
Intent browseintent=new Intent(Intent.ACTION_VIEW,
Uri.parse("http://www.example.com/index.php?iduser="+ scanContent));
startActivity(browseintent);
with below code
Intent browseintent=new Intent(this, SecondActivity.class);
browseintent.putExtra("url","http://www.example.com/index.php?iduser="+ scanContent);
startActivity(browseintent);
This will open the secondactivity with url in intent extras. You can set it to your edittext or you can use it directly to your webview.
You can receive the url in the second activity using the following code
String url = getIntent().getExtras().getString("url");
You can use it in your button click as follows
b1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String url = getIntent().getExtras().getString("url");
wv1.getSettings().setLoadsImagesAutomatically(true);
wv1.getSettings().setJavaScriptEnabled(true);
wv1.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
wv1.loadUrl(url);
}
});

You try this, it should open link with webview:
WebSettings settings = webView.getSettings();
settings.setJavaScriptEnabled(true);
settings.setAllowContentAccess(true);
settings.setDomStorageEnabled(true);
webView.setWebViewClient(new WebViewClient());
webView.loadUrl("https://vk.com/zabroshkiborika");

Cannot click on interstitial ad in WebView fragment

I have made an AdvanceWebView Application.
In that I have made a function to show interstitialAd in "fragmentActivity", that means whenever I download something from that webview that Ad will show up but it isn't clickable.
I think my ad is showing behind that fragment or something like that or maybe some other issue.
And when Vedio Ads are showen, the countdown of that ad also doesn't woprking.
I can see the Ad but it isn't clickable and if I click on any part of Ad, Logcat
is showing this => "I/HwSecImmHelper: mSecurityInputMethodService is null"

How do I display ProgressDialog using Fragment

I have a Fragment activity that has a ListFragment on the left and a Fragment on the right that has a WebView. The functionality works fine but I would like to display a progress dialog showing "Loading..." while the web page finishes loading. How can I accomplish this seemingly trivial task?
Below is my code:
public class ArticleListActivity extends FragmentActivity implements
ArticleListFragment.OnArticleSelectedListener {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.articlelist_fragment);
}
public void onArticleSelected(String contentLink) {
ArticleViewerFragment viewer = (ArticleViewerFragment) getSupportFragmentManager()
.findFragmentById(R.id.articleview_fragment);
if (viewer == null || !viewer.isInLayout()) {
Intent showContent = new Intent(getApplicationContext(),
ArticleViewerActivity.class);
showContent.setData(Uri.parse(contentLink));
startActivity(showContent);
} else {
viewer.updateUrl(contentLink);
}
}
}
Here is my FragmentActivity
public class ArticleViewerActivity extends FragmentActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.articleview_fragment);
Intent launchingIntent = getIntent();
String content = launchingIntent.getData().toString();
ArticleViewerFragment viewer = (ArticleViewerFragment) getSupportFragmentManager()
.findFragmentById(R.id.articleview_fragment);
viewer.updateUrl(content);
}
}
and here is my Fragment
public class ArticleViewerFragment extends Fragment {
private ProgressDialog progressBar;
private WebView viewer = null;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
viewer = (WebView) inflater.inflate(R.layout.webview_layout, container, false);
viewer.loadUrl("file:///android_asset/default.html");
return viewer;
}
public void updateUrl(String newUrl) {
if (viewer != null) {
viewer.loadUrl(newUrl);
}
}
}

Use this code:
final ProgressDialog pd = ProgressDialog.show(this, "", "Loading...", true);
pd.setCancelable(false);
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setSupportZoom(true);
webview.getSettings().setBuiltInZoomControls(true);
webview.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
if (pd != null && pd.isShowing()) {
pd.dismiss();
}
}
});
webview.loadUrl("file:///android_asset/default.html");

Need help in debugging NullPointerException in Android

That error means your activity timed out.
I don't understand why you call:
aboutframe.setWebViewClient
multiple times. You can try to replace if's with if else's:
/*...*/
else if(frname != null&frpath!= null){
/*...*/
else if(rname != null&rpath!= null){
/*...*/

put all your code between
try
{
your Code here...
}
catch(NullPointerException e)
{
e.printStackTrace();
}

You better use && instead of &. The latter is "binary and", you want to use "logical and".
