지금 튜너 응용 프로그램을 만들려고하는데 두 가지 오류가 있습니다. 둘 다 처리기를 기반으로합니다.제대로 처리기를 사용하는 방법
이mHandler.post(new Runnable() {
mHandler = new Handler(getMainLooper());
첫 번째 줄은 방법 '포스트 (인 java.lang.Runnable)를'해결할 수있는 결과, 그리고 두 번째 라인 결과는 '방법을 확인할 수 :
public class Pitch extends Fragment {
private static final String TAG = "Pitch";
private TextView tv_pitch;

Tuner.PitchDetectedListener listener = new Tuner.PitchDetectedListener() {
@Override
public void onPitchDetected(double pitch, double amplitude) {
Log.d(TAG, "Pitch: " + pitch + " Amplitude: " + amplitude);
if (amplitude > 1000000.0) {
double doublePitch = pitch * 2;
double halfPitch = pitch/2;

내 오류는이 라인에 getMainLooper. '
아무도 잘못 될지 파악할 수 있습니까?
고쳐! 감사! –
