안녕하세요. 모바일 개발자가 꿈인 학생입니다.
제가 EditText를 이용하여 EditText를 getText().toString() 해서 받은 값을 유튜브에 검색을 하는 프로젝트를 만들어 보려 합니다. 코드는 아래와 같이 입력했습니다.
하지만,, 에뮬레이터에 구동을 시켜보니,,, 텍스트를 입력하고 버튼을 누르면 비정상 종료 되진 않는데 아무런 결과도 나오지 않더라고요.. 그래서 중간 중간 Log값을 찍게 하면 Log값은 또 잘 찍어 냅니다.
코드의 어떤 부분이 문제일까요? 도와주십시오 부탁드립니다.
<SearchActivity.java>
public class SearchActivity extends Fragment {
private RecyclerView recyclerView;
private SearchAdapter adapter;
private EditText editText;
RequestQueue queue;
@Override
public View onCreateView(final LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

editText = view.findViewById(R.id.editText);
recyclerView.setHasFixedSize(true);

button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String url = "https://www.googleapis.com/youtube/v3/search?"
+ "part=snippet&q=" + editText.getText().toString()

StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {

}
}

}
}
<SearchData.java>
public class SearchData {
String title;
String thumb;
String videoId;
public SearchData(String title, String thumb, String videoId) {
this.title = title;
this.thumb = thumb;
this.videoId = videoId;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getThumb() {
return thumb;
}
public void setThumb(String thumb) {
this.thumb = thumb;
}
public String getVideoId() {
return videoId;
}
public void setVideoId(String videoId) {
this.videoId = videoId;
}
}
에뮬레이터에는 이렇게만 나옵니다..
