"팝업 - 커스텀다이얼로그"
- 팝업창의 레이아웃을 xml파일로 inflate하여 임의로 지정이 가능하다.
- StudyActivity에서 SWAP2 버튼을 클릭하면 RadioButton이 뜬다.
이때 RadioButton은 꼭 RadioGroup안에 묶어주어야 중복선택을 방지할 수 있다.
RadioGroup에서 RadioButton들을 나열하는 방법은 android:orientation로 지정가능하다.
'Inflater'
}else if(view.getId() == R.id.swap_bt2){
//인플레이터
LayoutInflater Inf = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = Inf.inflate(R.layout.activity_custom_dialog, null, false); //팝업창 레이아웃 미리 짜둔 거
//라디오버튼 중복 체크 안되도록 radiogroup으로 xml에서 묶어줘야 함
RadioButton korRb = v.findViewById(R.id.kor_r);
final RadioButton engRb = v.findViewById(R.id.eng_r);
engRb.setChecked(isEng);
//다이얼로그
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("한영모드 전환");
builder.setView(v);
builder.setNegativeButton("취소", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int i) {
}

public void onClick(DialogInterface dialog, int i) {
if(isEng != engRb.isChecked()){
isEng = engRb.isChecked();

}
}
});
builder.create().show();
}
}
"INTENT(화면전환)"
-StudyActivity에서 화면전환 버튼을 클릭하면 OptionActivity 페이지로 넘어가게되고
Back을 누르면 다시 되돌아온다.
-여기서도 역시 한/영 모드 설정이 가능하다.
StudyActivity에서의 코드
}else if(view.getId()==R.id.swap_bt3){ //인텐트로 화면전환
Intent intent = new Intent(this, com.example.ex_voca.OptionActivity.class);
intent.putExtra("isEng", isEng);
startActivityForResult(intent, 1000);OptionActivity에서의 코드
boolean isEng = getIntent().getBooleanExtra("isEng", false); //플래그
engRb.setChecked(isEng);
findViewById(R.id.btn).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
int result = engRb.isChecked() ? 0 : -1; //이건 짧게 줄인 버전
