I'm new to android and I need much help for everything I do. Thanks for your help.
I've got already this now:

use in this way

}
});
webview.setWebViewClient(new WebViewClient() {

{

return true;
}
});
webview.setWebChromeClient(new WebChromeClient(){
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url != null && url.startsWith("http://")) {
view.getContext().startActivity(
new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
return true;
} else {
return false;
}
}
});
webview.loadUrl("http://www.sherdle.com/apphosting/dd");
}
#Override
public void onBackPressed (){
if(webview.canGoBack()) webview.goBack();
else super.onBackPressed();
}
First make sure you have webview in your layout. Also make sure you have the following line in your manifest.
<uses-permission android:name="android.permission.INTERNET" />
Then you add that in your onCreate. It may not be the best, but it'll suffice.
Sorry, but how can you not understand where to insert that piece of code if you have exactly that same method already overridden? Look where it says:
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.loadUrl(url);
return true;
}
If you want to change the behaviour above, simply replace these two lines specified by that in the first code snippet.
I've got a feeling you don't really understand anonynous inner classes, as you also try to set a WebChromeClient twice - that doesn't really make sense. I suggest you do some reading on the matter.
Also, the shouldOverrideUrlLoading(...) method is defined by a WebViewClient, not a WebChromeClient. That's a case of simply consulting the documentation.

backbutton on my android webview

I tried to add a back button to my android webview but i've got this error:
The method onBackPressed() of type new WebViewClient(){} must override or implement a supertype method
This is my Java file:
package sherdle.donald.duck.app;
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class WebPageLoader extends Activity
{
WebView webview;
final Activity activity = this;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.main);
WebView 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 void onBackPressed() {
// do something on back.
return;
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.loadUrl(url);
return true;
}
});
webView.loadUrl("http://example.com");
}
}
Thanks for your help.
According to the doc, there is no onBackPressed method in the WebViewClient class. Did you want to Override it on your activity ?
try smthing like this:
package sherdle.donald.duck.app;
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class WebPageLoader extends Activity
{
WebView webView;
final Activity activity = this;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.main);
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("http://example.com");
}
#Override
public void onBackPressed (){
if(webView.canGoBack()) webView.goBack();
else super.onBackPressed();
}
}
You have to override the onkeyDown() method in your Activity.
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if(event.getAction() == KeyEvent.ACTION_DOWN){
switch(keyCode)
{
case KeyEvent.KEYCODE_BACK:
if(mWebView.canGoBack() == true){
mWebView.goBack();
}else{
finish();
}
return true;
}
}
return super.onKeyDown(keyCode, event);
}
Try this
package sherdle.donald.duck.app;
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class WebPageLoader extends Activity
{
WebView webview;
final Activity activity = this;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.main);
webView = (WebView) findViewById(R.id.webview);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://example.com");
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;
}
});
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
switch (keyCode) {
case KeyEvent.KEYCODE_BACK:
if(mWebView.canGoBack() == true)
webview.goBack();
else finish();
break;
default:
break;
}
return super.onKeyDown(keyCode, event);
}
}
And this method should be override in Activty.
WebView webView = (WebView) findViewById(R.id.webview);
Change it to:
webView = (WebView) findViewById(R.id.webview);
and then use the second answer - works like a charm!

Android webview loading dialog

I'm trying to implement a loading dialog in my webview application but whatever I do it just won't work.
What I want is the following, everytime someone clicks a link in the webview the loading dialog has to popup like this:
(source: wordpress.com)
And when the loading is done it has to disappear. Can anyone show me how to do it in my own source? I've tried a lot of things but there's always an issue so I really don't know how to.
This is my WebviewActivity:
import android.content.res.Configuration;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.view.Window;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class WebviewActivity extends MainActivity {
private WebView myWebView;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.main);
myWebView = (WebView)findViewById(R.id.webview);
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
myWebView.setWebViewClient(new WebViewClient());
myWebView.requestFocus(View.FOCUS_DOWN);
myWebView.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
case MotionEvent.ACTION_UP:
if (!v.hasFocus()) {
v.requestFocus();
}
break;
}
return false;
}
});
}
#Override
public void onResume() {
super.onResume();
if ( isOnline() == true )
myWebView.loadUrl(webLink);
else if ( isOnline() == false )
showNoConnectionDialog();
}
#Override
public void onConfigurationChanged(Configuration newConfig){
super.onConfigurationChanged(newConfig);
}
}
Thank you very much for your help!!
You have to override the WebViewClient like this,
webview.setWebViewClient(new WebViewClient(){
#Override
public void onPageFinished(WebView view, final String url) {
progressDialog.cancel();
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
progressDialog.show();
}
});
webview.loadUrl(TwitterUrl);
This is my final solution:
myWebView.setWebViewClient(new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
progressDialog.show();
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, final String url) {
progressDialog.dismiss();
}
});
This can be possible with WebChromeClient. It does worked for me.
Code snippet :
progressDialog.show(); // Add before page load
webView.setWebChromeClient(new HelpWebChromeClient());
private class HelpWebChromeClient extends WebChromeClient {
#Override
public void onProgressChanged(WebView view, int newProgress) {
if(newProgress == 100)
progressDialog.dismiss();
}
}
