11-2. 팝업대화상자

※ CustomLayoutDialog

 - 커스텀 뷰는 레이아웃 xml 파일을 만들어서 안드로이드 기본 Alert Dialog 틀에 안의 형식만 바꿔준다.

※ 구현

MainActivity

public class MainActivity extends Activity {

      Button btn;

      

      @Override

      protected void onCreate(Bundle savedInstanceState) {

            super.onCreate(savedInstanceState);

            setContentView(R.layout.activity_main);

            

            btn = (Button) findViewById(R.id.bt_01);

            btn.setOnClickListener(listener);

                  

      }

      

      OnClickListener listener = new OnClickListener() {

            

            @Override

            public void onClick(View v) {

                  // TODO Auto-generated method stub

                  

                  //Dialog 부분에 적용할 레이아웃을 세팅한다.

                  LinearLayout ll = (LinearLayout)View.inflate(MainActivity.this, R.layout.custom_dialog, null);

                  //텍스트를 입력받을 부분을 세팅

                  final EditText et = (EditText)ll.findViewById(R.id.ev_01);

                  new AlertDialog.Builder(MainActivity.this)

                        .setTitle("점심메뉴")

                        //AlertDialog와 다르게 setView가 생겼다... view 부분을 우리가 만든 레이아웃으로 바꾼다.

                        .setView(ll)

                        .setIcon(R.drawable.ic_launcher)

                        .setPositiveButton("OK", new DialogInterface.OnClickListener() {

                              @Override

                              public void onClick(DialogInterface dialog, int which) {

                                    // TODO Auto-generated method stub

                                    String msg = et.getText().toString();

                                    Toast.makeText(MainActivity.this, msg , Toast.LENGTH_SHORT).show();

                              }

                        })

                        .setNegativeButton("NO", new DialogInterface.OnClickListener(){

                              @Override

                                    public void onClick(DialogInterface dialog, int which) {

                                          // TODO Auto-generated method stub
