[Android] dialog 버튼 닫힘 막기 (Builder, AlertDialog)

문제점

다이얼로그에서 버튼을 클릭하면 닫히는 것을 막으려고 한다. 

참고사이트

해결방안

기존 리스너는 버튼만 만들어주고 AlertDialog 객체를 통해 오버라이딩해서 사용한다. 

그리고 아래 조건문을 통해 dimiss()를 제어한다.

코드

protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		tvName = (TextView) findViewById(R.id.tvName);
		btnClick = (Button) findViewById(R.id.btnClick);

		btnClick.setOnClickListener(new View.OnClickListener() {
			public void onClick(View v) {
				dialogView = (View) View.inflate(asdasd.this, R.layout.dialog,
						null);

				AlertDialog.Builder builder = new AlertDialog.Builder(
						asdasd.this);
				builder.setMessage("Test input data");
				builder.setView(dialogView);
				builder.setPositiveButton("ok",
						new DialogInterface.OnClickListener() {
							@Override
							public void onClick(DialogInterface dialog,
									int which) {
							}
						});
				builder.setNegativeButton("clear",
						new DialogInterface.OnClickListener() {
							@Override
							public void onClick(DialogInterface dialog,
									int which) {
							}
						});
				final AlertDialog dialog = builder.create();
				dialog.show();

				dlg_edt_name = (EditText) dialogView
						.findViewById(R.id.dlg_edt_name);

				dialog.getButton(AlertDialog.BUTTON_POSITIVE)
						.setOnClickListener(new View.OnClickListener() {
							@Override
							public void onClick(View v) {
								Boolean wantToCloseDialog = true;

								tvName.setText(dlg_edt_name.getText());

								if (wantToCloseDialog)
									dialog.dismiss();
							}
						});
				dialog.getButton(AlertDialog.BUTTON_NEGATIVE)
						.setOnClickListener(new View.OnClickListener() {
							@Override
							public void onClick(View v) {
								Boolean wantToCloseDialog = false;

								dlg_edt_name.setText("");

								if (wantToCloseDialog)
									dialog.dismiss();

							}
						});
			}
		});
	}
