Android Dialog Box Example

Android Dialog Box Example...
Open xml file and below code:

<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">

<Button

android:id="@+id/button1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignParentLeft="true"

android:layout_alignParentTop="true"

android:layout_marginLeft="24dp"

android:layout_marginTop="17dp"

android:text="CLOSE"

android:onClick="close" />

</RelativeLayout>

Now open java file and paste below code

package selecom.alert;

importandroid.os.Bundle;

importandroid.app.Activity;

importandroid.app.AlertDialog;

importandroid.app.AlertDialog.Builder;

importandroid.app.Dialog;

importandroid.content.DialogInterface;

importandroid.view.View;

importandroid.widget.Toast;

public class MainActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

}

public void close(View v)

{

onCreateDialog(10);

}

protected Dialog onCreateDialog(int id)

{

switch(id)

{

case 10:

Builder builder=newAlertDialog.Builder(this);

builder.setMessage("Activity will close!!!");

builder.setTitle("Warning...");

builder.setIcon(R.drawable.warning_image);

//button

builder.setNegativeButton("No", new DialogInterface.OnClickListener() {

@Override

public voidonClick(DialogInterface dialog, int which)

{

Toast.makeText(getApplicationContext(), "Nothing happened", Toast.LENGTH_LONG).show();

}

});

//button

builder.setPositiveButton("yes", new DialogInterface.OnClickListener() {

@Override

public voidonClick(DialogInterface dialog, int which)

{

finish();

}

});

//button

builder.setNeutralButton("Thinking", newDialogInterface.OnClickListener() {

@Override

public voidonClick(DialogInterface dialog, int which)

{

Toast.makeText(getApplicationContext(), "i have to think", Toast.LENGTH_LONG).show();

}

});

AlertDialog dialog=builder.create();

dialog.show();

}

return super.onCreateDialog(id);

}

}

We can use maximum three buttons in dialog box by default and builder is used to create dialog box. Sequence of the buttons to appear on box: positive, neutral than negative.
