Android Working with WebView - Building a App Browser

Android’s Web View permits you to integrate a webpage as an area of the app. Web View comes with all the options that of a desktop browser like managing history, cookies, HTML 5 support and heap a lot of. victimization web view you'll be able to build very cool apps like group action HTML 5 games within the app.

In this article we tend to  planning to learn the essential usage of Web View ranging from displaying a netpage to putting together an easy in-app browser that has some web site and search web address.

1:Create a android project in MainActivity.xml put below code for web browser design

main_activity.xml :

 <?xml version="1.0" encoding="utf-8"?>  
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"  
 xmlns:app="http://schemas.android.com/apk/res-auto"  
 xmlns:tools="http://schemas.android.com/tools"  
 android:layout_width="match_parent"  
 android:layout_height="match_parent"  
 android:padding="10dp"  
 tools:context="com.example.aaru.mybrowser.MainActivity"> 

 <EditText  
 android:id="@+id/editSearch"

 android:layout_width="wrap_content"

 android:layout_height="wrap_content"

 android:layout_alignParentLeft="true"

 android:layout_alignParentStart="true"

 android:layout_alignParentTop="true"

 android:ems="10"

 android:hint="https://www.google.com"

 android:inputType="none" />

 <Button  
 android:id="@+id/buttonSearch"

 android:layout_width="wrap_content"

 android:layout_height="wrap_content"

 android:layout_alignParentEnd="true"

 android:layout_alignParentRight="true"

 android:backgroundTint="@color/colorAccent"

 android:layout_alignParentTop="true"

 android:layout_toRightOf="@+id/editSearch"

 android:text="Search" />

 <Button  
 android:id="@+id/buttonGoogle"

 android:layout_width="wrap_content"

 android:layout_height="wrap_content"

 android:backgroundTint="#f75252"

 android:layout_marginTop="96dp"

 android:text="Google"

 android:layout_below="@+id/buttonSearch"

 android:layout_alignParentLeft="true"

 android:layout_alignParentStart="true"

 android:layout_alignParentRight="true"

 android:layout_alignParentEnd="true" /> 

 <Button  
 android:id="@+id/buttonFacebook"

 android:layout_width="wrap_content"

 android:layout_height="wrap_content"

 android:layout_marginTop="58dp"

 android:text="Facebook"

 android:layout_below="@+id/buttonGoogle"

 android:layout_alignParentLeft="true"

 android:layout_alignParentStart="true"

 android:backgroundTint="#45c2c9"

 android:layout_alignParentRight="true"

 android:layout_alignParentEnd="true" /> 

 <Button  
 android:id="@+id/buttonGmail"

 android:layout_width="wrap_content"

 android:layout_height="wrap_content"

 android:layout_alignParentEnd="true"

 android:layout_alignParentLeft="true"

 android:layout_alignParentRight="true"

 android:backgroundTint="#b34fda"

 android:layout_alignParentStart="true"

 android:layout_below="@+id/buttonFacebook"

 android:layout_marginTop="60dp"

 android:text="Gmail" /> 

 </RelativeLayout>  

Main Activity.java : In this class implantation the web browser design

 package com.example.aaru.mybrowser;

 import android.content.Intent;

 import android.support.v7.app.AppCompatActivity;

 import android.os.Bundle;

 import android.view.View;

 import android.widget.Button;

 import android.widget.EditText;

 public class MainActivity extends AppCompatActivity implements View.OnClickListener 

{ 

 Button buttonSearch,buttonGoogle,buttonFacebook,buttonGmail;  
   EditText editSearch; 

 @Override  

protected void onCreate(Bundle savedInstanceState) { 

 super.onCreate(savedInstanceState);

 setContentView(R.layout.activity_main); 

 editSearch=(EditText)findViewById(R.id.editSearch);

 buttonSearch= (Button) findViewById(R.id.buttonSearch);

 buttonGoogle= (Button) findViewById(R.id.buttonGoogle); 

 buttonFacebook= (Button) findViewById(R.id.buttonFacebook); 

 buttonGmail= (Button) findViewById(R.id.buttonGmail);  
     //all id get

 buttonSearch.setOnClickListener(this); 

 buttonGoogle.setOnClickListener(this); 

 buttonFacebook.setOnClickListener(this); 

 buttonGmail.setOnClickListener(this); 

 }  
   @Override

 public void onClick(View v) {

 Intent i=new Intent(MainActivity.this,WebViewActivity.class);

 if (v.equals(buttonSearch)){

 String url=editSearch.getText().toString();

 i.putExtra("k1",url);  
       startActivity(i); 

 }else if (v.equals(buttonGoogle))

{ 

 i.putExtra("k1","https://google.co.in"); 

 startActivity(i); 

 }else if (v.equals(buttonFacebook)){ 

 i.putExtra("k1","https://facebook.com"); 

 startActivity(i); 

 }else if (v.equals(buttonGmail)){

 i.putExtra("k1","https://mail.google.com"); 

 startActivity(i); 

 }  
   }  
 }  

2.Create empty activity name is webview activity put below code in web_view_activity.xml and WebViewActivity.java

web_view_activity.xml :

 <?xml version="1.0" encoding="utf-8"?>  
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"  
 xmlns:app="http://schemas.android.com/apk/res-auto"  
 xmlns:tools="http://schemas.android.com/tools"  
 android:layout_width="match_parent"  
 android:layout_height="match_parent"  
 android:orientation="vertical"  
 tools:context="com.example.aaru.mybrowser.WebViewActivity">  
 <WebView  
 android:layout_width="match_parent"  
 android:layout_height="match_parent"  
 android:id="@+id/webView"  
 ></WebView>  
 </LinearLayout>  

WebViewActivity.java :

 package com.example.aaru.mybrowser;  
 import android.support.v7.app.AppCompatActivity;  
 import android.os.Bundle;  
 import android.webkit.WebView;  
 import android.webkit.WebViewClient;  
 import android.widget.Toast;  
 public class WebViewActivity extends AppCompatActivity {  
   WebView webView;  
   @Override 

 protected void onCreate(Bundle savedInstanceState) {  
     super.onCreate(savedInstanceState);  
     setContentView(R.layout.activity_web_view);  
     webView=(WebView)findViewById(R.id.webView);  
     String url=getIntent().getStringExtra("k1");  
     if (url.contains("https://")){  
       webView.loadUrl(url);  
       webView.setWebViewClient(new WebViewClient());  
       webView.getSettings().setJavaScriptEnabled(true);  
       //let's run it  
       //Give a Internet Permission in manifests file  
     }else {  
       Toast.makeText(this, "Something Went wrong", Toast.LENGTH_SHORT).show();  
     }  
   }  
 }
