news_site_link_one=(TextView)findViewById(R.id.news_SourceLink_text_one_t_webview);
news_site_like_two=(TextView)findViewById(R.id.news_SourceLink_text_two_t_webview);
news_site_link_one.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent webviewintent = new Intent(getApplicationContext(), News_WebView.class);
webviewintent.putExtra("webviewurl", webviewurl);
startActivity(webviewintent);
}
});
news_site_like_two.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent webviewintent = new Intent(getApplicationContext(), News_WebView.class);
webviewintent.putExtra("webviewurl2", webviewurl2);
startActivity(webviewintent);
}
});
here my webview code
String SourceURL;
WebView webview;
final Activity activity = this;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_news__web_view);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
setContentView(R.layout.activity_news__web_view);
Intent intent =this.getIntent();
if(intent!=null)
SourceURL = intent.getStringExtra("webviewurl");
if(SourceURL.equals("webviewurl")) {
webview = (WebView) findViewById(R.id.webView);
webview.getSettings().setJavaScriptEnabled(true);
}
if(SourceURL.equals("webviewurl2")) {
webview = (WebView) findViewById(R.id.webView);
webview.getSettings().setJavaScriptEnabled(true);
}
webview.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress)
{
activity.setTitle("Loading...");
activity.setProgress(progress * 100);
if(progress == 100)
activity.setTitle(R.string.app_name);
}
});
webview.setWebViewClient(new WebViewClient() {
#Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
// Handle the error
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
webview.loadUrl(SourceURL);
}
Use containsKey
Bundle data =getIntent().getExtras();
if(data.containsKey("webviewurl"))
{
SourceURL =data.getString("webviewurl");
}
else if(data.containsKey("webviewurl2"))
{
SourceURL =data.getString("webviewurl2");
}
Here is code snippet I tried for multiple urls
Myactivity.java
public void openWeb() {

Please help me. How to disable webview open new page ? I want to disable this behaviour, so if I click on a link, don't load it. I've tried this solution and edited a bit for myselft, but not worked. My webviewclient code:
public class MainActivity extends AppCompatActivity {
private WebView webView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = (WebView) findViewById(R.id.webView);
webView.setWebViewClient(new myWebClient());
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://example.com");
webView.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView webView, int errorCode, String description, String failingUrl) {
try {
webView.stopLoading();
} catch (Exception e) {
}
if (webView.canGoBack()) {
webView.goBack();
}
webView.loadUrl("about:blank");
AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();
alertDialog.setTitle("Error");
alertDialog.setMessage("Check your internet connection and try again.");
alertDialog.setButton(DialogInterface.BUTTON_POSITIVE, "Try Again", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
finish();
startActivity(getIntent());
}
});
alertDialog.show();
super.onReceivedError(webView, errorCode, description, failingUrl);
}
});
}
public class myWebClient extends WebViewClient
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
#Override
// This method is used to detect back button
public void onBackPressed() {
if(webView.canGoBack()) {
webView.goBack();
} else {
// Let the system handle the back button
super.onBackPressed();
}
}
}
In your WebViewClient, you can load only specific url that you want as below,
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(url.equals("my url")) {
view.loadUrl(url);
}
return true;
}
Firstly you use web view you create web activity like this:
xml layout:-
<?xml version="1.0" encoding="utf-8"?>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/webView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
WebView Activity:-
public class WebViewActivity extends AppCompatActivity {
#BindView(R.id.webView1)
WebView webView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_web_view);
// i am using intent getting the value from like this
Intent intent2 = getIntent();
Bundle bundle = intent2.getExtras();
String link = bundle.getString("Agreement_URL");
Log.e("link---",""+link);
String file_type=bundle.getString("file_type");
if(file_type.equals("PDF"))
{
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("https://docs.google.com/gview?embedded=true&url="+link);
setContentView(webView);
}
else
{
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl(link);
}
}
/** Method on BackPressed Button click*/
public void onBackPressed(){
super.onBackPressed();
/** Activity finish*/
finish();
}
pass the value like this from previous activity
Intent intent =new Intent(context, WebViewActivity.class);
intent.putExtra("Agreement_URL","http://54.183.245.32/uploads/"+ finalUploadDoc);
intent.putExtra("file_type","PDF");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
Log.e("ggg",""+ finalUploadDoc);
context.startActivity(intent);
try this it helps you
I have two ImageButton with two different url. When I click the image, it returns an white screen.I don't know what is the problem. Any edit or suggestions are welcome.
Thanks!
main activity
public class main extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
ImageButton amazon = (ImageButton)findViewById(R.id.imagebutton1);
ImageButton flipkart = (ImageButton)findViewById(R.id.imagebutton2);
amazon.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(getApplicationContext(),"Amazon",Toast.LENGTH_LONG).show();// display the toast on home button click

Intent intent = new Intent(main.this, MainActivity.class);
intent.setData(Uri.parse("http://www.flipkart.in"));
startActivity(intent);
}
});
}
my webview activity
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WebView htmlWebView = (WebView) findViewById(R.id.webView);
htmlWebView.setWebViewClient(new CustomWebViewClient());
WebSettings webSetting = htmlWebView.getSettings();
webSetting.setJavaScriptEnabled(true);
webSetting.setDisplayZoomControls(true);
htmlWebView.loadUrl("");
}
class CustomWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
Do you want to load Url in your app or want to open via External Browser. anaway I'm given the snipped code for the open the url in webview as given below in your application as:
WebView mynews;
ProgressBar pb;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.newsreadscreen);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
pb= (ProgressBar) findViewById(R.id.progress_bar);
mynews= (WebView) findViewById(R.id.mynews);
mynews.getSettings().setJavaScriptEnabled(true);
mynews.getSettings().setDefaultFontSize(17);
mynews.getSettings().setDisplayZoomControls(true);
mynews.getSettings().setDomStorageEnabled(true);
mynews.getSettings().setLoadsImagesAutomatically(true);
mynews.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
pb.setVisibility(View.VISIBLE);
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
pb.setVisibility(View.GONE);
super.onPageFinished(view, url);
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
pb.setVisibility(View.VISIBLE);
super.onPageStarted(view, url, favicon);
}
});
mynews.loadUrl("https://www.google.co.in");
this is the code I have Edited
amazon.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(getApplicationContext(),"Amazon",Toast.LENGTH_LONG).show();// display the toast on home button click
Intent intent = new Intent(main.this, MainActivity.class);
intent.putExtra("url","http://www.amazon.com");
startActivity(intent);
}
});
get the value on the MainActivity.Class onCreateMethod like below
String url=getIntent().getStringExtra("url");
mynews.loadUrl(url);
I need a progress bar at the centre of my android webview it must be shown before the page loads and hides when the page is loaded. How can it be done? Can anyone help me?
This is my code for webview:
Bundle extras = getIntent().getExtras();
String title;
final String url;
if (!Datacon.checkInternetConnection(this)) {
Toast.makeText(getApplicationContext(), "Check your Internet Connection!", Toast.LENGTH_LONG).show();
} else {
if (extras != null) {
title = extras.getString("title");
url = extras.getString("url");
TextView text=(TextView) findViewById(R.id.textView1);
text.setText(title);
final WebView myWebView =(WebView)findViewById(R.id.WebView);
myWebView.loadUrl(url);
myWebView.getSettings().setLoadWithOverviewMode(true);
myWebView.getSettings().setUseWideViewPort(true);
myWebView.getSettings().setBuiltInZoomControls(true);
myWebView.getSettings().setLayoutAlgorithm(LayoutAlgorithm.SINGLE_COLUMN);
loadingProgressBar=(ProgressBar)findViewById(R.id.progressbar_Horizontal);
myWebView.setWebViewClient(new WebViewClient(){
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
});
Button refresh = (Button) actionBar.getCustomView().findViewById(R.id.but2);
refresh.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
myWebView.loadUrl(url);
}
});
}
}}
}
You need to override a couple of more methods in the WebViewClient :
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
loadingProgressBar.setVisibility(View.VISIBLE);
}
#Override
public void onPageFinished(WebView view, String url) {
loadingProgressBar.setVisibility(View.GONE);
}
I'm assuming loadingProgressBar is a class field.
PS: As a side note I believe you overriding shouldOverrideUrlLoading is unnecessary. The default behaviour is to load the url, as you instruct it to do.
private void initializeProgressBar() {
if (progressBar == null){
progressBar = new ProgressDialog(this);
progressBar.setMessage(Constants.LOADING_MESSAGE);
progressBar.setCancelable(false);
}
}
Handler peogressBar = new Handler(){
public void handleMessage(android.os.Message msg) {
try{
switch (msg.what) {
case 1:
initializeProgressBar();
if(!progressBar.isShowing())
progressBar.show();
break;
case 2:
if (progressBar != null && progressBar.isShowing()) {
progressBar.dismiss();
progressBar = null;
}
break;
}
}catch(Exception e){
e.printStackTrace();
}
};
};
wv_graphLink = (WebView) findViewById(R.id.wv_graphLink);
wv_graphLink.getSettings().setJavaScriptEnabled(true);
wv_graphLink.getSettings().setBuiltInZoomControls(true);
wv_graphLink.getSettings().setSupportZoom(true);
wv_graphLink.setInitialScale(1);
wv_graphLink.getSettings().setLoadWithOverviewMode(true);
wv_graphLink.getSettings().setUseWideViewPort(true);
// wv_graphLink.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
// wv_graphLink.setScrollbarFadingEnabled(false);
peogressBar.sendEmptyMessage(1);
wv_graphLink.setWebChromeClient(new WebChromeClient(){
public void onProgressChanged(WebView view, int progress) {
if(progress == 100){
peogressBar.sendEmptyMessage(2);
}
}
});
wv_graphLink.loadUrl("Your url");
There is a website that I use which opens up in a new window on a desktop, now what I want to do is replicate that in an app. The code I have so far includes the setsupportformultiplewindows but when I click the link that opens the new window, nothing happens. my code for the browser is as follows
public class WebActivity extends Activity {
private WebView mWebView = null;
private EditText mInputUrl = null;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
super.onCreate(savedInstanceState);
getWindow().setFeatureInt( Window.FEATURE_PROGRESS, Window.PROGRESS_VISIBILITY_ON);
setContentView(R.layout.activity_web_view);
Intent intent = getIntent();
String thesite = intent.getStringExtra(MainPage.EXTRA_MESSAGE);
mInputUrl = (EditText)findViewById(R.id.input_url);
Button button = (Button)findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String baseurl = "http://";
String url = baseurl + mInputUrl.getText().toString();
mWebView.loadUrl(url);
}
});
mWebView = (WebView) findViewById(R.id.webview);
mWebView.loadUrl(thesite);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setWebViewClient(new WebViewClient());
mWebView.getSettings().setAllowFileAccess(true);
mWebView.getSettings().setPluginState(WebSettings.PluginState.ON);
mWebView.getSettings().setBuiltInZoomControls(true);
mWebView.getSettings().setLoadWithOverviewMode(true);
mWebView.getSettings().setUseWideViewPort(true);
mWebView.getSettings().setGeolocationEnabled(true);
mWebView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
mWebView.getSettings().setSupportMultipleWindows(true);
final Activity MyActivity = this;
mWebView.setWebChromeClient(new WebChromeClient() {
public void onGeolocationPermissionsShowPrompt(String origin, android.webkit.GeolocationPermissions.Callback callback) {
callback.invoke(origin, true, false);
}
There is further code below but not related to my issue
EDIT:
Here is an image which shows how I would ideally like it. https://www.dropbox.com/s/gwllmjebtw13rzw/webview.png
Try this :
mWebView.setWebChromeClient(new WebChromeClient() {
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
#Override
public void onLoadResource(WebView view, String url) {
super.onLoadResource(view, url);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
Intent webIntent = new Intent(WebViewActivity.this,
NewWebViewActivity.class);
webIntent .putExtra("urlparam", url);
startActivity(webIntent);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
}
}
In shouldOverrideUrlLoading(),you can check the url and open it in another activity using startActivity().
Hope this helps.
I am having a WebView and i am getting data in it from a WebService.
my problem is, there are so many url's in the data i am getting and when a user click on it, then it should load on a WebViewon next page not on a browser.
How can i achieve that.? I tried shouldOverrideUrlLoading but it's not working.
Try this.
public class WebViewActivity extends Activity {
private ProgressDialog progressBar;
#Override
protected void onCreate(Bundle savedInstanceState) {

webView.setWebViewClient(new MyWebViewClient());
webView.loadUrl("http://www.mysite.com/android.php");
}
private class MyWebViewClient extends WebViewClient {
#Override
public void onPageFinished(WebView view, String url) {
if (progressBar != null && progressBar.isShowing()) {
progressBar.dismiss();
}
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
System.out.println("here");
//Upadated code..........
Bundle bundle = new Bundle();
//Add your data from getFactualResults method to bundle
bundle.putString("NextUrl", url);
Intent i = new Intent(WebViewActivity.this, NextActivity.class);
i.putExtras(bundle);
startActivity(i);
//-----------------------
Log.i("Hi", "WEb nextttt");
return true;
}
}
}
NextActivity
public class NextActivity extends Activity {
WebView wv1;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main2);
Bundle bundle = getIntent().getExtras();
//Extract the data…
String url = bundle.getString("NextUrl");
Log.i("Hi", "Get next");
wv1 = (WebView) findViewById(R.id.webView1);
wv1.getSettings().setJavaScriptCanOpenWindowsAutomatically(false);

return false;
}
});
try {
