I want to load a HTML form into webview however it is not working for me and Im wondering if its even possible? This is the code I have.
Thanks

}
private class TimeClient extends WebViewClient {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
}
also
don't do this : final Activity MyActivity = this;
instead use "MyActivity.this" inside WebChromeClient.onProgressChanged
also there is a gotcha with webView you cant do "loadData(data,mime,enc)" for some reason you need to use :
web.loadDataWithBaseURL("fake://host/path",htmldata.toString(), mimetype, encoding, "");
"fake://host/path" is a fake url but you could also use your homepage or something.
so something like :
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
getWindow().setFeatureInt( Window.FEATURE_PROGRESS, Window.PROGRESS_VISIBILITY_ON);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.setWebViewClient(new TimeClient());
mWebView.setInitialScale(1);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setDomStorageEnabled(true);
//mWebView.loadData(html, "text/html", "utf-8");
//final Activity MyActivity = this;
mWebView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress)
{
//Make the bar disappear after URL is loaded, and changes string to Loading...
MyActivity.setTitle("Loading...");
MyActivity.setProgress(progress * 100); //Make the bar disappear after URL is loaded
// Return the app name after finish loading
if(progress == 100)
MyActivity.this.setTitle(R.string.app_name);
}
});
}
public void onStart() {
main();
mWebView.loadData("fake://host/path",html, "text/html", "utf-8");
}
public void onStop() {
// some JSoup disconnect code
}
then the webView will load every time the app is launched.
move view.loadUrl(url); to your onStart method.
if you was a loading icon, override onPageStarted & onPageFinished in WebViewClient. then you can use WebChromeClient.onProgressChanged to update your progress bar.

Is their something i'm doing wrong? Do i have to include some lib?
I've tried adding the Youtube Api but that didn't help.
Edit#1: This is the WebView code
On some instance the Audio Playback works but instead of video it's just a rotating circle animation trying to load the video.

You need to enable javaScript.WebView myWebView = (WebView) findViewById(R.id.webview);
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
EDIT:
You are setting the WebClient for webview twice.
`webView1.setWebViewClient(new WebViewClient()
{
#Override
public boolean shouldOverrideUrlLoading(WebView view,
String url) {
// TODO Auto-generated method stub
view.loadUrl(url);
return true;
}
});`
You aren't really doing anything here thats different from the original implementation and this code isn't even running because you replace the webview with another webclient so delete this.
` runOnUiThread(new Runnable() {
#Override
public void run() {
// Code for WebView goes here
webView1.loadUrl(url);
}
});
`
Delete this too, just type webview1.loadUrl(url) no need for a runOnUiThread.
` webView1.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
Delete this too, its this line that is causing your issue. `
I have webview included in my app. I want to navigate webpage history, but I don`t know how to do that. Please help me. My Main.java below:
package com.abc.test;
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class Main extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
WebView wv = (WebView)findViewById(R.id.webview);
WebSettings webSettings = wv.getSettings();
webSettings.setJavaScriptEnabled(true);
wv.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
wv.loadUrl("http://www.google.com");
}
}
Here is the code
public void goBackInWebView(){
WebBackForwardList history = webView.copyBackForwardList();
int index = -1;
String url = null;
while (webView.canGoBackOrForward(index)) {
if (!history.getItemAtIndex(history.getCurrentIndex() + index).getUrl().equals("about:blank")) {
webView.goBackOrForward(index);
url = history.getItemAtIndex(-index).getUrl();
Log.e("tag","first non empty" + url);
break;
}
index --;
}
// no history found that is not empty
if (url == null) {
finish();
}
}
I want to add this code to my java file:
webView.setWebViewClient(new WebViewClient(){
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;
}
}
}
But I don't know where. 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;

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

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() {

webview.loadUrl("http://www.sherdle.com/apphosting/dd");
}
#Override
public void onBackPressed (){
if(webview.canGoBack()) webview.goBack();
else super.onBackPressed();
}
}
But I get this error on my LoadUrl line:
Multiple markers at this line
- Syntax error, insert "AssignmentOperator Expression" to complete
Expression
- Syntax error, insert ";" to complete FieldDeclaration
- Syntax error, insert ")" to complete MethodInvocation
- Syntax error, insert "}" to complete ClassBody

use in this way

}
}
});
webview.loadUrl("http://www.sherdle.com/apphosting/dd");
}
#Override

}
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.
Here's one of the tabs I have that loads a page.
package realstrat.cfostudio.magazineapp;
import android.app.Activity;
import android.app.ProgressDialog;
import android.content.Context;

public class TabActivity3 extends Activity {
WebView mWebView;
private ProgressDialog progressBar;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.web);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setPluginsEnabled(true);
mWebView.loadUrl("--company URL--");
mWebView.setWebViewClient(new FirstTabWebViewClient());
}
#Override
public void onSaveInstanceState(Bundle savedInstanceState) {
savedInstanceState.putBoolean("OverviewMode", mWebView.getSettings().getLoadWithOverviewMode());
mWebView.saveState(savedInstanceState);
super.onSaveInstanceState(savedInstanceState);
}
#Override
public void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
((WebView)findViewById(R.id.webview1)).restoreState(savedInstanceState);
if (savedInstanceState.getBoolean("OverviewMode") == false) {
((WebView)findViewById(R.id.webpageview)).getSettings().setLoadWithOverviewMode(false);
((WebView)findViewById(R.id.webpageview)).getSettings().setUseWideViewPort(false);
}
else {
((WebView)findViewById(R.id.webpageview)).getSettings().setLoadWithOverviewMode(true);
((WebView)findViewById(R.id.webpageview)).getSettings().setUseWideViewPort(true);
}
return;
}
private class FirstTabWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// YouTube video link
if (url.startsWith("vnd.youtube"))
{
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
return (true);
}
if (url.endsWith("-m.html")){
mWebView.getSettings().setLoadWithOverviewMode(false);
mWebView.getSettings().setUseWideViewPort(false);
}
else {
mWebView.getSettings().setLoadWithOverviewMode(true);
mWebView.getSettings().setUseWideViewPort(true);
}
view.loadUrl(url);
return true;
}
public void onPageStarted(WebView view, String url, Bitmap favicon){
progressBar = ProgressDialog.show(TabActivity3.this, "", "Loading...", true);
}
public void onPageFinished(WebView view, String url) {
progressBar.hide();
if (url.endsWith("-m.html")){

}
else {
mWebView.getSettings().setLoadWithOverviewMode(true);
mWebView.getSettings().setUseWideViewPort(true);
}
return;
}
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Context context = getApplicationContext();
CharSequence text = "Desc: " + description;
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
return;
}
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
mWebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
Once in a while it will crash with a nullPointerException on the line progressBar.hide() under onPageFinished(). That doesn't make any sense since onPageStarted() starts the progressBar, and onPageStarted always comes before onPageFinished(). Why is this?
This only happens like, once in 10 times or something, which is really confusing to me.
It usually happens (always?) when the activity is being started for the first time.
try this
if(progressBar!=null)
progressBar.hide();
Maybe the Activity has been restarted in between the two callbacks? Try rotating the phone while the progressBar is shown to see what the results are.
Try to load progress bar as singleton object. If you create anther progress bar object before hide first one then second progress bar will crash in hide().
if(_progressBar == null)
_progressBar = new ProgressDialog(this);
I have a ListView of some websites. What I want is that when a user clicks on listview, those websites are shown in same webview instead of starting a new activity. How can I do that?
Here is my webview java:
import android.app.Activity;
import android.app.ProgressDialog;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class Aftonbladet extends Activity {
private WebView myWebView;
/** Called when the activity is first created. */
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && myWebView.canGoBack()) { // Enables browsing to previous pages with the hardware back button
myWebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
final ProgressDialog pd = ProgressDialog.show(this, "", "Loading...",
true);
myWebView = (WebView) findViewById(R.id.mywebview);
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.getSettings().setSupportZoom(true);
myWebView.getSettings().setBuiltInZoomControls(true);
myWebView.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
if(pd.isShowing() && pd!=null)
{
pd.dismiss();
}
}
});
myWebView.loadUrl("http://www.google.com");
}
}
For website loading in webview, you can use like this:
webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
webview.loadUrl("http://www.linkedin.com");
webview.getSettings().setPluginState(PluginState.ON);
webview.getSettings().setAllowFileAccess(true);
webview.setWebViewClient(new MyWebViewClient());
and your MyWebViewClient class is:
private class MyWebViewClient extends WebViewClient {
#Override
//show the web page in webview but not in web browser
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl (url);
return true;
}
}
Hope it helps
EDIT: It looks like what you want is to pass the url from one activity to another. To achieve that you can use either SharedPreferences or putExtras to the intent like this in your ListView Activity:
Intent myIntent = new Intent(this, Aftonbladet.class);
Bundle b = new Bundle();
b.putString("url", theURL);
myIntent.putExtra(b);
startActivity(myIntent);
and then on your WebView Activity you can get that value:
Bundle b = this.getIntent().getExtras();
String url = b.getString("url");
