Android Activity as a Dialog

Show/Display Android Activity as a Dialog

Show/Display Android Activity as a Dialog. Here We will learn the simplest way to display an Android activity as a Dialog.  When you will display the android activity as a dialog, it will work as a modal dialog. That means user can’t access it’s parent activity unless until the  dialog activity will be destroyed. Once the dialog activity will close, then only it’s parent activity will get focus.

Android Activity as a Dialog Example with Source Code

Here we will discuss about How to show an Android Activity as a Dialog with example. We have taken 2 activity in the attached example to show an activity as a dialog. In the example when we will click on a button from the first activities, then we will show the second activity as a dialog. We added one Edittext and 2Buttons in the second activity for the test purpose only.

import android.view.Menu;

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.view.View;

import android.widget.Button;

public class ActivityOne extends Activity {

    /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        final Button buttonYes = (Button) findViewById(R.id.button_show_activity_two);  

        buttonYes.setOnClickListener(new View.OnClickListener()

        {

@Override

public void onClick(View v) 

{

//open second activity(ActivityTwo)as a dialog here

       Intent intent = new Intent(getBaseContext(),ActivityTwo.class);

startActivity(intent);

}

});

    }

}

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

// add below line if you want to remove title for the activity dialog

this.requestWindowFeature(Window.FEATURE_NO_TITLE);

setContentView(R.layout.activity_two);

final Button buttonYes = (Button) findViewById(R.id.button_ok);

buttonYes.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

finish();

EditText editText = (EditText) findViewById(R.id.edit_text);

String str = editText.getEditableText().toString();

if (0 != str.length()) {

Toast.makeText(getBaseContext(), "Hello Mr." + str,

Toast.LENGTH_SHORT).show();

}

}

});

final Button buttonNo = (Button) findViewById(R.id.button_cancel);

buttonNo.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

finish();
