You can use alert dialog

    deleteCheckBox.setOnClickListener(deleteRelatedThumbnail(deleteCheckBox));

 View.OnClickListener deleteRelatedThumbnail(final CheckBox checkBox) {

        return new View.OnClickListener() {
            public void onClick(View v) {
                int index = checkBox.getId();
                if (((CheckBox) v).isChecked() && deleteVideoFile(index - 1)){
                    AlertDialog.Builder builder=new AlertDialog.Builder(MainActivity.this);// use you activity name
              builder.setMessage("Are you sure you want to delete? ")
                      .setPositiveButton("Ok",
                new DialogInterface.OnClickListener() {

                    @Override
                    public void onClick(DialogInterface dialog, int which) {

                      bitMapsAvailable.remove(index - 1);
                    bitMapsFilePath.remove(index - 1);
                    Toast.makeText(MainActivity.this, "Selected video file is deleted successfully.", Toast.LENGTH_SHORT).show();
                    showThumbnails();

                    }
                })

        .setNegativeButton("Cancel",new DialogInterface.OnClickListener() {

                    @Override
                    public void onClick(DialogInterface dialog, int which) {
             Toast.makeText(MainActivity.this, "Not deleted", Toast.LENGTH_SHORT).show();

                    }
                });
               AlertDialog dialog=builder.create();
               dialog.show();

                    // if(deleteVideoFile(index-1)){

                }else{
                    Toast.makeText(MainActivity.this, "Not deleted", Toast.LENGTH_SHORT).show();
                }

            }
        };
    }

Just user alertdialog for it:

private void showLocationDialog() {  

AlertDialog.Builder builder = new AlertDialog.Builder(yOURActivity.this);
builder.setTitle(getString(R.string.dialog_title));
builder.setMessage(getString(R.string.dialog_message));

String positiveText = getString(android.R.string.ok);
builder.setPositiveButton(positiveText,
        new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // positive button logic
    }
});

String negativeText = getString(android.R.string.cancel);
builder.setNegativeButton(negativeText,
        new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // negative button logic
    }
});

AlertDialog dialog = builder.create();
// display dialog
dialog.show();

}
