Displaying Information In Dialog in Android

Hello guys, How are you today? I hope you all be in the best of your life.

Today, we are going to see how to show the information in dialog in Android. So , lets get started.

Download 

1) First of all, create an Android Application Project.

2) Next go to "res/layout/activity_main.xml" and create a button for which we are going to implement OnClickListener. The code looks like

<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"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Click Me"
        android:id="@+id/click" />

</RelativeLayout>

3) Next make an Android xml file in the "res/layout/" folder and create a TextView in there. For our case the name is "show.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" >
    
    <TextView 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="You are awesome"
        android:textColor="#ffffff"/>
    

</LinearLayout>

4) Next go to "src/your_package_name/MainActivity.java" and implement OnClickListener for the click button. The code looks like

import android.app.Activity;
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 implements OnClickListener {
    Button click;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        click = (Button) findViewById(R.id.click);
        click.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        switch(v.getId()) {
        case R.id.click : Intent i = new Intent(this, Show.class);
        startActivity(i);
        break;
        }
    }

}

5) Now, we have to create a class "Show.java" in the "src/your_package_name" . In Show.java we are going to display the show.xml.

import android.app.Activity;
import android.os.Bundle;

public class Show extends Activity{
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.show);
        
    
    }

}

6) Now open AndroidManifest,xml and create an Show Activity with the dialog theme.

For our case its like

<activity android:theme="@android:style/Theme.Dialog" android:name="com.example.dialog_blog.Show" />

Now we are done. Post your questions in the comment. I will be happy to answer those.
