I am developing an android app. which is using webview to render a html page but it stays blank while the page loads. I want to add a loading spinner in the action bar so the user knows that something is loading and it not blank.
Please can anyone guide me how to do that.
My existing code -
package com.pranavsethi.dpsrkp;
import android.annotation.TargetApi;
import android.app.ActionBar;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Build;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.webkit.DownloadListener;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class Achievements extends Activity{
private WebView mWebView;
#TargetApi(Build.VERSION_CODES.HONEYCOMB)
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webvew_client_layout);
ActionBar actionBar = getActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
//For web view
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true); //enable javascript
mWebView.getSettings().setBuiltInZoomControls(true); //enable zoom
mWebView.getSettings().setDisplayZoomControls(false);
mWebView.getSettings().setLoadWithOverviewMode(true);
mWebView.getSettings().setUseWideViewPort(true);
mWebView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
mWebView.setScrollbarFadingEnabled(true);
mWebView.setDownloadListener(new DownloadListener() {
#Override
public void onDownloadStart(String url, String userAgent,
String contentDisposition, String mimetype,
long contentLength) {
// handle download, here we use brower to download, also you can try other approach.
Uri uri = Uri.parse(url);
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);
}
});
mWebView.loadUrl("http://pranavsethi.tk"); // name of website to load
mWebView.setWebViewClient(new HelloWebViewClient()); //removing loading progressbar
}
private class HelloWebViewClient extends WebViewClient{ //our web client
#Override
public void onReceivedError(WebView view, int errorCode, //Code for checking the internet connection and return the error if fails
String description, String failingUrl) {
Intent intent = new Intent(Achievements.this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
return;
}
#Override
public boolean shouldOverrideUrlLoading(WebView webview, String url)
{
webview.loadUrl(url);
return true;
}
}
#Override
public boolean onKeyDown(int KeyCode, KeyEvent event)
{
if ((KeyCode)== KeyEvent.KEYCODE_BACK && mWebView.canGoBack())
{
mWebView.goBack();
return true;
}
return super.onKeyDown(KeyCode, event);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case android.R.id.home:
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
overridePendingTransition (R.anim.right_slide_in, R.anim.fade_out);
break;
default:
return super.onOptionsItemSelected(item);
}
return true;
}
#Override
public void onBackPressed()
{
this.finish();
overridePendingTransition (0, R.anim.right_slide_out);
return;
}
}
SOLUTION
Add the following -
requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
setProgressBarIndeterminateVisibility(true);
After -
super.onCreate(savedInstanceState);
And this in your WebViewClient
private class HelloWebViewClient extends WebViewClient{
#Override
public boolean shouldOverrideUrlLoading(WebView webview, String url){
webview.loadUrl(url);
setProgressBarIndeterminateVisibility(true);
return true;
}
#Override
public void onPageFinished(WebView webview, String url){
super.onPageFinished(webview, url);
setProgressBarIndeterminateVisibility(false);
}
}

If anybody have any idea Please help me. Also please comment your suggestions on the code/logic. (I am very new to android programming)
Internet if off. Its different scenario you must add check internet connection before load.
Or onRwleceiveError is different case. When you load wrong url or utl you entered is not working

}
}
}
try it & let me know the result

I've pretty much followed all the necessary steps for adding a ProgressBar to my WebView using ActionBarSherlock, but I don't get any results on pre-Android 4.0. Can anyone help? I've imported Window from ABS, added requestWindowFeature(Window.FEATURE_PROGRESS); before setting content, i just don't know what to do. Please don't tell me to follow the samples, since I've tried that and I've gotten no results. Thank you.
Here is the code for MainActivity.class
package com.twk95.webviewtest;
import android.content.Intent;
import android.os.Bundle;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import com.actionbarsherlock.app.SherlockActivity;
import com.actionbarsherlock.view.Menu;
import com.actionbarsherlock.view.MenuItem;
import com.actionbarsherlock.view.Window;
public class MainActivity extends SherlockActivity {
public static WebView webView;
final SherlockActivity MyActivity = this;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.activity_main);
webView = (WebView) findViewById(R.id.WebView);
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView webview, String url) {
webview.loadUrl(url);
return true;
}
});
webView.loadUrl("http://www.google.com");
webView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
MyActivity.setTitle("Loading...");
MyActivity.setProgress(progress * 100);
setSupportProgressBarVisibility(true);
if (progress == 100) {
MyActivity.setTitle(R.string.app_name);
setSupportProgressBarVisibility(false);
}
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getSupportMenuInflater().inflate(R.menu.webview_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.webReload:
webView.reload();
break;
case android.R.id.home:
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
return true;
}
return false;
}
}
Make sure that the requestWindowFeature method is using com.actionbarsherlock.app.SherlockActivity.requestWindowFeature(long featureId) then use setSupportProgress(int progress) to update it rather than using MyActivity.setProgress()
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.os.Bundle;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;

final Activity activity = this;
#Override

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

}
#Override

}
#Override

{
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!
