Get data from website

Tutorial about how to get data from website with WebView in Android Studio. Open Android Studio and create a project (see here how). Application name for this example is WebView. In MainActivity.java write the following code:

package com.view.web.webview;
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.activity_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);
            }
        });
    }
}

In activity_main.xml write the following code to create a button which at click open a website:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <Button
        android:id="@+id/buttonUrl"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/red_button"
        android:textColor="#ffffff"
        android:textSize="20dp"
        android:text="GO TO android-coffee.com" />

</RelativeLayout>

Create new activity: right click on package and choose New -> Activity -> Blank Activity. Name new activity WebViewActivity and click finish. In the new activity created WebViewActivity.java  write the following code with website you want. For this example I choose android-coffee.com:

package com.view.web.webview;
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.activity_web_view);

        webView = (WebView) findViewById(R.id.webView1);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.loadUrl("https://android-coffee.com");

    }

}

In activity_web_view.xml write the following code:

<?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"
    />

Create new .xml file and name it red_button. Right click on drawable folder and choose New -> XML -> Layout XML File. Completes field Layout File Name: red_button and click Finish.   In new file created red_button.xml write the following code to create gradient on button:

<?xml version="1.0" encoding="utf-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:state_pressed="true" >
    <shape>
      <solid android:color="#ef4444" />
      <stroke
          android:width="1dp"
          android:color="#000000" />
      <corners android:radius="6dp" />
      <padding
          android:left="10dp"
          android:top="10dp"
          android:right="10dp"
          android:bottom="10dp" />
    </shape>
  </item>
  <item>
    <shape>
      <gradient
          android:startColor="#ef4444"
          android:endColor="#000000"
          android:angle="270" />
      <stroke
          android:width="1dp"
          android:color="#992f2f" />
      <corners android:radius="6dp" />
      <padding
          android:left="10dp"
          android:top="10dp"
          android:right="10dp"
          android:bottom="10dp" />
    </shape>
  </item>
</selector>

Add internet permission in AndroidManifest.xml file.

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

That is all. Run the application and see the result. An activity opens with a button to click to open a website.   Download here the project with all files. Download here the application for mobile phone. Watch the video tutorial to get data from website with WebView in  Android Studio:
