In this tutorial we are going to discuss about How to create webView in Android ?

At first create an empty project in android studio .

1 . activity_main.xml

Here we create a button name as “Open Browser” and webView inside our activity_main.xml .

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity"
    android:orientation="vertical">

<Button
    android:id="@+id/btn"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Open Browser"/>

<WebView
    android:id="@+id/wv"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"></WebView>

</LinearLayout>

2. MainActivity.java

Now we find the id of btn and webView inside our MainActivity.java file.

package com.example.root.webview;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.webkit.WebView;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {
WebView wv;
Button btn;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

wv=(WebView)findViewById(R.id.wv);
btn=(Button) findViewById(R.id.btn);

btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
wv.getSettings().setJavaScriptEnabled(true);
wv.loadUrl("https://www.google.com/");
bt.setVisibility(View.GONE);
}
});
}
}

3. Android Manifest

we add Internet uses permission inside our AndroidManifest.xml file .

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.root.webview">

    <uses-permission android:name="android.permission.INTERNET"/>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
               <action 
                   android:name="android.intent.action.MAIN"/>

               <category 
               android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Now we run the project in android mobile or Emulator.
