public class Test extends Activity{
TextView tv;

         super.onCreate(savedInstanceState);

         setContentView(R.layout.test);

         button initialization code..
        b.setOnclickListener(new OnClickListener() {

            @Override

            public void popup(final int position)

        final Dialog dialog = new Dialog(Test.this);
        TextView view
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

        view = (TextView) dialog.findViewById(R.id.view1);
        view .setOnClickListener(new OnClickListener() {

            @Override

public void popup() {

    final Dialog dialog = new Dialog(this);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.popup);

    dialog.findViewById(R.id.textView1).setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            // remove dialog
            dialog.dismiss();

            // change color of text
            ((TextView) findViewById(R.id.change_my_color)).setTextColor(Color.GREEN);
        }

    });

    dialog.show();
}

将自定义对话框的结果返回给活动
