I have a webview in a fragment, the webview has multiple links. I want when the user clicks on one of those links, for example, a Readmore link it opens the in-app browser I created (BrowserActivity). How can I achieve this?
BrowserActivity.java
public class BrowserActivity extends AppCompatActivity {
private String Url ;
private WebView Tecwebview;
private ProgressBar progressBar;
ImageButton back, forward, stop, refresh, homeButton;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_browser);
back = (ImageButton) findViewById(R.id.back_arrow);
forward = (ImageButton) findViewById(R.id.forward_arrow);
stop = (ImageButton) findViewById(R.id.stop);
refresh = (ImageButton) findViewById(R.id.refresh);
homeButton = (ImageButton) findViewById(R.id.home);
progressBar = (ProgressBar) findViewById(R.id.probar);
progressBar.setMax(100);
Tecwebview = (WebView) findViewById(R.id.tecwebview);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
Tecwebview.loadUrl(Url);
if (savedInstanceState != null) {
Tecwebview.restoreState(savedInstanceState);
} else {
Tecwebview.getSettings().setJavaScriptEnabled(true);
Tecwebview.getSettings().setUseWideViewPort(true);
Tecwebview.getSettings().setLoadWithOverviewMode(true);
Tecwebview.getSettings().setSupportZoom(true);

progressBar.setVisibility(ProgressBar.VISIBLE);
}

This is for browser activity to make the links in browser activity webview only opens in the webview
public class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
CookieManager.getInstance().setAcceptCookie(true);
return true;
}
According to my understanding you have a url e.g, www.xyz.com and you want to load your Activity when the user clicks on it.
If that is true then try following code but change the value of targeUrl to your link address and also launch the activity in the area where I have wrote comment...
Tecwebview.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
String targetUrl = "https//www.somelinksaddress.com/me/you";
if (targetUrl.equals(url)) {
// Start your activity here
} else {
view.loadUrl(url);
}
return true;
}
});

This below line should do your work
webSettings.setCacheMode(WebSettings.LOAD_DEFAULT)
I'm building an Webview app which displays my website. My website contains clickable mobile number, I need to open dialer when user clicks it.
I've gone through this question.
Since I'm new to Android development I don't know exactly where to paste that code.
Here Is my Mainactivity.java code
public class MainActivity extends AppCompatActivity {
private WebView webView;
private ProgressBar mProgressBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView= findViewById(R.id.web);
mProgressBar= findViewById(R.id.progressbar);
mProgressBar.setMax(100);
webView.loadUrl("https://");
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebViewClient(new WebViewClient());
webView.setWebChromeClient(new WebChromeClient(){
#Override
public void onProgressChanged(WebView view, int newProgress) {
super.onProgressChanged(view, newProgress);
mProgressBar.setProgress(newProgress);
}
#Override
public void onReceivedTitle(WebView view, String title) {
super.onReceivedTitle(view, title);
}
#Override
public void onReceivedIcon(WebView view, Bitmap icon) {
super.onReceivedIcon(view, icon);
}
});
}
#Override
public void onBackPressed(){
if (webView.canGoBack()) {
webView.goBack();
}else {
finish();
}
}}
You need to Override the shouldOverrideUrlLoading() method in setWebViewClient()
SAMPLE CODE
webView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
progressBar.setProgress(progress);
}
});
webView.setWebViewClient(new WebViewClient() {
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(url.contains("tel:"))
{
Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse(url));
startActivity(intent);
return true;
}else {
progressBar.setVisibility(view.VISIBLE);
view.loadUrl(url);
return true;
}
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
progressBar.setVisibility(View.GONE);
}
});
I have a webview as fragment which extends fragment class in my fragment navigation drawer. I want to detect the back press of this fragment.
Below is code i m using to detect the back press on the fragment
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){
// handle back button
getActivity().getSupportFragmentManager().beginTransaction().replace(R.id.container,new MyFragment()).commit();

I have a code in which the progress dialog appears along with main layout. I want the progress dialog to be on the forefront and the main layout in background just like its showing the link enter link description here.
public class MainActivity extends Activity {
private WebView webView;
private EditText urlEditText;
private ProgressBar progress;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
urlEditText = (EditText) findViewById(R.id.urlField);
webView = (WebView) findViewById(R.id.webView);
webView.setWebViewClient(new MyWebViewClient());
progress = (ProgressBar) findViewById(R.id.progressBar);
progress.setVisibility(View.GONE);
Button openUrl = (Button) findViewById(R.id.goButton);
openUrl.setOnClickListener(new OnClickListener() {
#SuppressLint("SetJavaScriptEnabled")
#Override
public void onClick(View view) {
String url = urlEditText.getText().toString();
if (validateUrl(url)) {
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl(url);
}
}
private boolean validateUrl(String url) {
return true;
}
});
}
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
progress.setVisibility(View.GONE);
MainActivity.this.progress.setProgress(100);
super.onPageFinished(view, url);
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
progress.setVisibility(View.VISIBLE);
MainActivity.this.progress.setProgress(0);
super.onPageStarted(view, url, favicon);
}
}
public void setValue(int progress) {
this.progress.setProgress(progress);
}
}
Try to use WebChromeClient instead of WebViewClient to show and update progress :
show pregress bar before call webview.loadUrl() :
if (validateUrl(url)) {
webView.getSettings().setJavaScriptEnabled(true);
progress.setVisibility(View.VISIBLE);
webView.loadUrl(url);
}
Update progress in onProgressChanged :
webView.setWebChromeClient(new WebChromeClient() {
#Override
public void onProgressChanged(WebView view, int newProgress) {
super.onProgressChanged(view, newProgress);
if (newProgress == 100) {
progress.setVisibility(View.GONE);
} else {
progress.setProgress(newProgress);
}
}
});
I'm developing an application in which I'm using webview to load certain websites. I also have customized actionbar on which I have website navigation button. Here is the view how my layout is looking like:
When I load website my all three buttons are visible, but I want them to be visible at that time only when user has clicked on some URL, so user easily understand the purpose of those buttons.
I have added all the functionalities to those button. Here is my code:
website_back = (ImageButton) cView.findViewById(R.id.website_back);
website_forward = (ImageButton) cView.findViewById(R.id.website_forward);
website_refresh = (ImageButton) cView.findViewById(R.id.website_refresh);
if (v.getId() == R.id.website_back) {
webview.goBack();
}
if (v.getId() == R.id.website_forward) {
webview.goForward();
}
if (v.getId() == R.id.website_refresh) {
webview.reload();
}
My WebViewClient:
private class HelloWebViewClient extends WebViewClient {
public void onPageStarted(WebView view, String url, Bitmap favicon) {
progress.setVisibility(View.VISIBLE);
super.onPageStarted(view, url, favicon);
}
public void onPageFinished(WebView view, String url) {
progress.setVisibility(View.GONE);
super.onPageFinished(view, url);
}
public boolean shouldOverrideUrlLoading(WebView view, String url) {
website_back.setImageResource(R.drawable.webview_back);
view.loadUrl(url);
return true;
}
}
How can I only show those buttons when user has clicked on some URL, on the website launched in the webview?
Any kind of help will be appreciated.
You need to attach a WebViewClient to the WebView to listen in on the URLs that are being fetched.
mWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(url.equals(mOriginalUrl)){
//initial url load, ignoring.
}
else {
//url was navigated to - do something
}
return super.shouldOverrideUrlLoading(view, url);
}
#Override
public void onPageFinished(WebView view, String url) {
//page has finished loading
}
});
this worked for me. hope it would be useful for you. try this
