Android WebView

Android WebView Example 

Android’s WebV allows you to open an own windows for viewing URL or custom html markup page.

In this tutorial, you will create two pages, a page with a single button, when you clicked on it, it will navigate to another page and display URL “google.com” in WebView component.

1. Android Layout Files

Create two Android layout files – “res/layout/main.xml” and “res/layout/webview.xml“.

File : res/layout/main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >
 
    <Button
        android:id="@+id/buttonUrl"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Go to http://www.google.com" />
 
</LinearLayout>

File : res/layout/main.xml – WebView example

<?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"
/>

2. Activity

Two activity classes, an activity to display a button, another activity display the  Web view with predefined   URL.

File : MainActivity.java


package com.abhi.android;
 
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
 
public class MainActivity extends Activity {
 
	private Button button;
 
	public void onCreate(Bundle savedInstanceState) {
		final Context context = this;
 
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
 
		button = (Button) findViewById(R.id.buttonUrl);
 
		button.setOnClickListener(new OnClickListener() {
 
		  @Override
		  public void onClick(View arg0) {
		    Intent intent = new Intent(context, WebViewActivity.class);
		    startActivity(intent);
		  }
 
		});
 
	}
 
}



File : WebViewActivity.java


package com.abhi.android;
 
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");
 
	}
 
}
