제목 표시 줄이없는 텍스트 선택은 눌림의 원인이됩니다.

Question

아래의 제목 표시 줄을 숨기면 작동합니다.

public class MainActivity extends ActionBarActivity { 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     requestWindowFeature(Window.FEATURE_NO_TITLE); 
     setContentView(R.layout.activity_main); 
    } 
} 

그러나 webView 또는 editText에서 단어 선택을 길게 클릭하면 응용 프로그램이 손상됩니다.

단어 선택은 Titlebar의 공간을 사용하기 때문입니다.

어떻게 해결할 수 있습니까?

Answer 1

귀하의 활동은 ActionbarActivity를 확장합니다. "예"이면 맞춤 테마를 작성해야합니다.
