</LinearLayout>이런 xml파일에 버튼 3개가 있고, 각 버튼을 누르면 그 버튼에 맞는 새창이 뜨도록 만들려고 하는데,
public class CategoryActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.category_layout);
// CategoryFragment를 화면에 표시합니다.
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.fragmentContainer, new HomeFragment())
.commit();
}
public void myListener1(View view) {
Intent intent = new Intent(getApplicationContext(), KoreaActivity.class);
startActivity(intent);
}
public void myListener2(View view) {
Intent intent = new Intent(getApplicationContext(), PopActivity.class);
startActivity(intent);
}
public void myListener3(View view) {
Intent intent = new Intent(getApplicationContext(), JapanActivity.class);
startActivity(intent);
}
}
이렇게 자바 파일이 있을때 onClick으로 설정해둔 버튼에 맞게 각각 설정된 class의 화면을 띄울려고 하는데 계속

이란 오류가 뜹니다...
public class KoreaActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.korea_layout);
}
}출력하게 할 자바에도 위 처럼 설정해 놨는데 왜 오류가 뜨는지 알 수가 없어 도움을 요청해 봅니다.
혹시 다른 코드도 필요하심 댓글로 달아드리겠습니다
제발 부탁드립니다!!
