Android 액티비티를 팝업(Popup)으로 띄우기, 데이터 주고받기

MainActivity.java

 

public class MainActivity extends AppCompatActivity {       TextView txtResult;         @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);           txtResult = (TextView)findViewById(R.id.txtResult);     }       //버튼     public void mOnPopupClick(View v){         //데이터 담아서 팝업(액티비티) 호출         Intent intent = new Intent(this, PopupActivity.class);         intent.putExtra("data", "Test Popup");         startActivityForResult(intent, 1);     }       @Override     protected void onActivityResult(int requestCode, int resultCode, Intent data) {         if(requestCode==1){             if(resultCode==RESULT_OK){                 //데이터 받기                 String result = data.getStringExtra("result");                 txtResult.setText(result);             }         }     } }

 

 

PopupActivity.java

 

public class PopupActivity extends Activity {       TextView txtText;         @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         //타이틀바 없애기         requestWindowFeature(Window.FEATURE_NO_TITLE);         setContentView(R.layout.popup_activity);           //UI 객체생성         txtText = (TextView)findViewById(R.id.txtText);           //데이터 가져오기         Intent intent = getIntent();         String data = intent.getStringExtra("data");         txtText.setText(data);     }       //확인 버튼 클릭     public void mOnClose(View v){         //데이터 전달하기         Intent intent = new Intent();         intent.putExtra("result", "Close Popup");         setResult(RESULT_OK, intent);           //액티비티(팝업) 닫기         finish();     }       @Override     public boolean onTouchEvent(MotionEvent event) {         //바깥레이어 클릭시 안닫히게         if(event.getAction()==MotionEvent.ACTION_OUTSIDE){             return false;         }         return true;     }       @Override     public void onBackPressed() {         //안드로이드 백버튼 막기         return;     } }

* 10 : 타이틀바 없애기

* 17-18 : Intent 에서 data 가져오기

* 25-27 : Intent로 data 전달하기

* 34-40 : 바깥 레이어를 눌러도 닫히지 않게 하기

* 43-46 : 안드로이드 백버튼 막기

* 팝업의 가로세로 길이는 직접 정해줍니다

 

 

AndroidMenifest.xml

 

<!-- 팝업 Activity -->         <activity             android:name=".PopupActivity"             android:theme="@android:style/Theme.Dialog" />

* Popup으로 띄울 Activity의 Theme를 바꿔줍니다

 

 

결과

* 팝업 호출(데이터 전달) -> 팝업에서 전달받은 데이터 보여줌 , 팝업 닫기(데이터 전달) -> 데이터 받아서 보여줌
