Android Concept: WebView With HTML Script Demo

Ø Create MainActivity.java class in src/package.

MainActivity.java

import android.annotation.SuppressLint;

import android.app.Activity;

import android.app.ProgressDialog;

import android.os.Bundle;

import android.webkit.WebView;

import android.webkit.WebViewClient;

public class MainActivity extends Activity {

private WebView webView1;

private ProgressDialog pd;

@SuppressLint("SetJavaScriptEnabled")

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

pd = ProgressDialog.show(this, "", "Loading...", true);

webView1 = (WebView) findViewById(R.id.webView1);

webView1.getSettings().setJavaScriptEnabled(true);

webView1.getSettings().setSupportZoom(true);

webView1.getSettings().setBuiltInZoomControls(true);

webView1.setWebViewClient(new WebViewClient() {

@Override

public void onPageFinished(WebView view, String url) {

if (pd.isShowing() && pd != null) {

pd.dismiss();

}

});

webView1.loadUrl("file:///android_asset/test.html");

}

Ø Create main.xml in res/layout.

main.xml

<?xml version="1.0" encoding="utf-8"?>

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

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="vertical" >

<WebView

android:id="@+id/webView1"

android:layout_width="match_parent"

android:layout_height="match_parent" />

</LinearLayout>

Ø Create test.html in assets.

test.html

<head>

<title>Internal Script</title>

</head>

<body>

document.write("Hello Javascript!")

</script>
