Android web browser download dialog
I am trying to implement a download dialog in my web browsing application, but whatever I do, it just won't work.
What I need is the following, every time someone clicks on a link in the web view, the download dialog should pop up like this:
(source: wordpress.com )
And when the download is complete, it should disappear. Can someone show me how to do this in my own source? I tried a lot of things, but there is always a problem, so I really don't know how to do this.
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);
}
}
Many thanks for the help !!

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();
}
});

You should override 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 possible using the WebChromeClient. This worked for me.
Snippet of code:
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();
}
}
