Question

I have two xml files, and two java files. In the first xml I have few buttons, and one of them is EXIT. In the java file i write in the onCreate:

Button exitButton = (Button) this.findViewById(R.id.button_exit);
    exitButton.setOnClickListener(this);

Then further down the code I write:

@Override
public void onClick(View v) {
    switch (v.getId()) {

    case R.id.button_exit:
        Intent switchtoExit = new Intent(StartActivity.this, ExitActivity.class);
        startActivityForResult(switchtoExit, MESSAGE_REQUEST);
        break;
    }
}

the second java files is called ExitActivity.java. In the manifest file I wrote:

<activity android:name=".ExitActivity" 
            android:label="@string/exit_title"
            android:theme="@android:style/Theme.Dialog"/>

In order to make the second xml file popup like a dialog.
My second java file is(the one that popup like a dialog):

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;

public class ExitActivity extends Activity implements OnClickListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        this.setContentView(R.layout.activity_exit);

        Button noExitButton = (Button) this.findViewById(R.id.exit_no_button);
        noExitButton.setOnClickListener(this);
        Button yesExitButton = (Button) this.findViewById(R.id.exit_yes_button);
        yesExitButton.setOnClickListener(this);

    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
        case R.id.exit_no_button:
            Toast.makeText(this, "Good Choice :-D", Toast.LENGTH_SHORT).show();
            break;
        case R.id.exit_yes_button:
            Toast.makeText(this, "So sad... \nnice playing with you...", Toast.LENGTH_SHORT).show();
            break;
        //break;
        }
    }
}

and my second java file has:

    <?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" 
    android:background="@color/red">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/exitTV"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/exit_body" 
            />

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal" >

            <Button
                android:id="@+id/exit_no_button"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="@string/exit_no_button" 
                android:layout_weight="1.0"
                />

            <Button
                android:id="@+id/exit_yes_button"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="@string/exit_yes_button" 
                android:layout_weight="1.0"
                />

        </LinearLayout>

    </LinearLayout>

</LinearLayout>

What I wanted to do is to have one button close the dialog, and the other button to stop the application. I tried finish(), and it worked just fine. but then when I added the onDestroy() method one button would restart the application, and the other just close it. Also, when I pressed the Back button, it would close the application.

Can anyone explain me how to get the following to happen:

1. When the dialog pops up, and I press the back button, it just closes the dialog?
2. When I press on exit button, it closes the application.
3. When I press on the Stay button it closes the dialog.

Thanks

You’re doing this the wrong way. Using a second activity is overkill. Use an AlertDialog, which you can easily make with AlertDialogBuilder. Set it to have a positive and a negative button. Set an OnClickListener for the positive button that calls finish on the only activity. There you go- 1 activity, and the dialog class itself will take care of popping up and closing itself.
