<?xml version="1.0" encoding="utf-8"?>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scrollbars="horizontal|vertical"
/>
If you have the webview defined in your xml, you can do the following:
android:scrollbars="horizontal|vertical"
You can do the following:
mWebView.setVerticalScrollBarEnabled(true);
mWebView.setHorizontalScrollBarEnabled(true);

What's wrong with this code?
Thank's for helping.
The button should open a new browser activity.
Currently I'm a beginner in android. Right now I'm trying to make my ListView item open a layout which contain WebView when any item is clicked. Each item will direct to a different page. But I'm not sure how can I achieve this. This is my code.
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi;
vi = LayoutInflater.from(getContext());
v = vi.inflate(R.layout.activity_listview, null);
}
FeedItem p = getItem(position);
if (p != null) {
TextView tt1 = (TextView) v.findViewById(R.id.title_text);
TextView tt2 = (TextView) v.findViewById(R.id.date_text);
if (tt1 != null) {
tt1.setText(p.getTitle());
}
if (tt2 != null) {
tt2.setText(p.getPubDate());
}
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
FeedItem q = getItem(position);
if(q.getLink() != null){
//Toast.makeText(getContext(), "" + q.getLink(), Toast.LENGTH_SHORT).show();
}
}
});
}
return v;
}
Your Question is totally opinion based. both can be used as per app's requirement.
Default Browser
it is easy to use just 4 or file lines and you are good to go. but it gets user out of application.
How to use it.
Intent intent= new Intent(Intent.ACTION_VIEW,Uri.parse(YOUR_URL));
startActivity(intent);
WebView
can be used as a part of application. you need to create on activity containing webview and call intent from where you want to open webview.
Example
Layout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<WebView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/webView" />
</RelativeLayout>
java
public class WebViewActivity extends Activity {
private WebView wv1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
wv1=(WebView)findViewById(R.id.webView);
wv1.getSettings().setLoadsImagesAutomatically(true);
wv1.getSettings().setJavaScriptEnabled(true);
wv1.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
wv1.loadUrl(your_url);
}
}
and just call this from where you want to open Webview.
Intent intent= new Intent(MainActivity.this,WebViewActivity.class);
startActivity(intent);
refer this link.
I hope it is clear.
You can modify little bit according to your requirement and need to put your import your package.
if(q.getLink() != null){
Intent intent = new Intent(getActivity(), BrowserActivity.class);
intent.putExtra("url", q.getLink());
startActivity(intent);
}
BrowserActivity
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.ImageView;
import android.widget.Toast;
import com.yourproject.R;
public class BrowserActivity extends FragmentActivity {
WebView webview;
public BrowserActivity() {
// Required empty public constructor
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.comment_detail);
String url = getIntent().getStringExtra("url");
Log.d("URL ", url);
webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setBuiltInZoomControls(true);
webview.getSettings().setSupportZoom(true);
webview.loadUrl(url);
webview.setWebViewClient(new WebViewClient() {
public void onPageStarted(WebView view, String url) {
}
public void onPageFinished(WebView view, String url) {
// do your stuff here
MyApplication.hideTransparentProgressDialog();
}
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(CommentDetails.this, description, Toast.LENGTH_SHORT).show();
}
});
}
}
comment_detail.xml
<include
android:id="#+id/headerTV"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
layout="#layout/title_bar_layout_job_info" />
<WebView
android:layout_below="#+id/headerTV"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/webview">
</WebView>
To open browser use intent:
String url = "https://www.google.com/";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
and for webview :
XML Code:
<?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"
/>
JAVA Code:
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
public class WebViewActivity extends Activity {
private WebView webView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://www.google.com");
}
}
you can also load your own html file on WebView.
Can anyone please help me check my code to see why it cannot be
launched in the app itself but directs me to a browser? ): Thanks!!

Where is the error? :D
It keeps opening up in the browser.
In the following line:
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
you're asking Android to open a URL using the intent constant ACTION_VIEW - so it defaults to the external browser.
Here a full example (taken from here) that shows how to open the url using a WebViewClient:
package com.paresh.webviewclientdemo;

WebView web;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
web = (WebView) findViewById(R.id.webview01);
web.setWebViewClient(new myWebClient());
web.getSettings().setJavaScriptEnabled(true);
web.loadUrl("http://www.google.com");
}
public class myWebClient extends WebViewClient
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
view.loadUrl(url);
return true;
}
}
// To handle "Back" key press event for WebView to go back to previous screen.
#Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if ((keyCode == KeyEvent.KEYCODE_BACK) && web.canGoBack()) {
web.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
I'm using eclipse. Just started with android web apps :) !
I want to create a web application that whenever it's open, it loads a website.
Nothing visual, no buttons.
This is the main blank code I have:

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();

http://cordova.apache.org/
Use this below code. It contains webview client which is safest one.
import android.app.Activity;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebView;
import android.webkit.WebViewClient;
/*
* Demo of creating an application to open any URL inside the application and clicking on any link from that URl
should not open Native browser but that URL should open in the same screen.
*/
public class WebViewClientDemoActivity extends Activity {
/** Called when the activity is first created. */
WebView web;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
web = (WebView) findViewById(R.id.webview01);
web.setWebViewClient(new myWebClient());
web.getSettings().setJavaScriptEnabled(true);
web.loadUrl("http://www.google.com");
}
public class myWebClient extends WebViewClient
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
view.loadUrl(url);
return true;
}
}
// To handle "Back" key press event for WebView to go back to previous screen.
#Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if ((keyCode == KeyEvent.KEYCODE_BACK) && web.canGoBack()) {
web.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
Hey all first Android project here...
I found this code for loading a website inside a webview:
package com.example.mainactivity;
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.Window;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MainActivity extends Activity {
private WebView mWebView;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_NO_TITLE);
mWebView = new WebView(this);
mWebView.loadUrl("http://www.google.com");
mWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
this.setContentView(mWebView);
}
#Override
public boolean onKeyDown(final int keyCode, final KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
mWebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
However, it tells me (when i am debugging it via Eclipse and my phone via USB) that:
webpage not available
What am i missing here? I know my phone has internet connection.
Ah.... i didn't have the permissions in my manifest file....
<uses-permission android:name="android.permission.INTERNET" />
