WebView

Hi!

     We can write both Android Standalone & Web applications,in this blogger i am going to explain about the web application only especially by calling the URL directly.

There are two ways to create the web application in android

1. Directly Call the URL By using WebView ,
2. By using HTML5, PhoneGap we can create the Web Applications.

In android we are using WebView to make executable Android application for our websites.

It is very simple to do it.

• Create an Object for WebView,
• Assign setting for like JavaScript Enable,Zooming Controlling  ,etc..,
• load your url to WebView object
• keep to manage the history if their is any previous page,
• in your XML create the WebView,

Java Code:

import android.annotation.SuppressLint;

import android.app.Activity;

import android.os.Bundle;

import android.view.KeyEvent;

import android.view.View;

import android.view.Window;

import android.webkit.WebChromeClient;

import android.webkit.WebView;

import android.webkit.WebViewClient;

import android.widget.Toast;

public class Pets extends Activity {

WebView webview;

@SuppressLint("SetJavaScriptEnabled")

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

getWindow().requestFeature(Window.FEATURE_PROGRESS);

getWindow().setFeatureInt(Window.FEATURE_PROGRESS,

Window.PROGRESS_VISIBILITY_ON);

webview = new WebView(this);

setContentView(webview);

setProgressBarVisibility(true);

webview.getSettings().setJavaScriptEnabled(true);

webview.getSettings().setBuiltInZoomControls(true);

webview.getSettings().setUseWideViewPort(true);

webview.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);

final Activity activity = this;

webview.setWebChromeClient(new WebChromeClient() {

public void onProgressChanged(WebView view, int progress) {

activity.setProgress(progress * 100);

}

});

webview.setWebViewClient(new WebViewClient() {

public void onReceivedError(WebView view, int errorCode,

String description, String failingUrl) {

Toast.makeText(activity, "Oh no! " + description,

Toast.LENGTH_SHORT).show();

}

});

webview.loadUrl("http://petsfacebook.in/index.php");

}

@Override

public boolean onKeyDown(int keyCode, KeyEvent event) {

if (event.getAction() == KeyEvent.ACTION_DOWN) {

switch (keyCode) {

case KeyEvent.KEYCODE_BACK:

if (webview.canGoBack() == true) {

webview.goBack();

} else {

finish();

}

return true;

}

}

return super.onKeyDown(keyCode, event);

}

}

XML Code:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:id="@+id/LinearLayout1"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:orientation="vertical"

    tools:context=".Pets" >

    <WebView

        android:id="@+id/webView1"

        android:layout_width="match_parent"

        android:layout_height="match_parent" />

</LinearLayout>

 In Your Android Manifest don't forget to give permission for Internet connection "android.permission.INTERNET"



Thank You!
