다음과 같은 오류가 발생 합니다. 아래 표시된 내 조각 파일에서 "getSupportFragmentManager () 메서드가 new View.OnClickListener () {} 유형에 대해 정의되지 않았습니다 ."

ABS와 적절한 가져 오기를 통해 참조되는 호환성 라이브러리가 있습니다. 호환성 라이브러리와 함께 ABS 라이브러리를 다시 설치하고 프로젝트를 정리하고 Eclipse를 다시 시작했지만 아무것도 작동하지 않았습니다.

기본적으로 대화 조각을 통해 날짜 선택기를 표시하도록 조각을 가져 오려고합니다. 날짜가 선택되면 해당 날짜를 기반으로 정보를 계산하는 데 사용할 수 있도록 조각으로 반환되어야합니다.

내 조각의 코드는 다음과 같습니다.

package com.owentech.abstabsviewpager;

    //Fragment Layout
    View view = inflater.inflate(R.layout.obstetricsfragment1, container, false);

    Button mPickLMPDate = (Button) view.findViewById(R.id.pickLMPDate);

    mPickLMPDate.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            LMPDatePickerDialogFragment d = LMPDatePickerDialogFragment.newInstance();
            d.show(getSupportFragmentManager(), "dialog");
        }

    });

    return view;
}

public Dialog onCreateDialog(Bundle savedInstanceState) {
    // TODO Auto-generated method stub

}

다음은 Dialog Fragment의 코드입니다.

public class LMPDatePickerDialogFragment extends ObstetricsFragment1 implements DatePickerDialog.OnDateSetListener {

    return d;
}

private int mLMPYear;

private int mLMPDay;

public Dialog onCreateDialog(Bundle savedInstanceState) {
    return new DatePickerDialog(getActivity(), this, mLMPYear, mLMPMonth, mLMPDay);
}

public void onDateSet(DatePicker view, int year, int month, int day) {
    mLMPYear = year;

you will get rid of this problem by making the activity that calls the dialog extend FragmentActivity

public class ObstetricsFragment1 extends FragmentActivity{

this is inherent to the support library, as seen in DIALOG SPECS and SUPPORT LIBRARY SPECS

---

Try changing your code to this:

public class ObstetricsFragment1 extends SherlockFragment{

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState)
{
    //Fragment Layout
    View view = inflater.inflate(R.layout.obstetricsfragment1, container, false);

    Button mPickLMPDate = (Button) view.findViewById(R.id.pickLMPDate);

    mPickLMPDate.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            LMPDatePickerDialogFragment d = LMPDatePickerDialogFragment.newInstance();
            FragmentManager fm = ObstetricsFragment1.this.getSherlockActivity().getSupportFragmentManager();
            d.show(fm, "dialog");
        }

    });

    return view;
}

---

I did a diff on Marco's answer to see what he actually recommended changing: just

d.show(getSupportFragmentManager(), "dialog");

to

FragmentManager fm = 
    ObstetricsFragment1.this.getSherlockActivity().getSupportFragmentManager();
d.show(fm, "dialog");

---

In case anyone is using SherlockActivity instead of SherlockFragment just extend the activity to SherlockFragmentActivity.

---

I had a similar problem loading a lesson project (https://developer.android.com/training/multiple-threads).

To resolve, I had to add an external jar (sdk/extras/android/support/v4/android-support-v4.jar).

Hope this helps.

You need to extend ObstetricsFragment1 from SherlockDialogFragment.

---

To get FragmentManager in a fragment call getChildFragmentManager(). See this.

Change this

mPickLMPDate.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        LMPDatePickerDialogFragment d = LMPDatePickerDialogFragment.newInstance();
        d.show(getSupportFragmentManager(), "dialog");
    }

});

to

mPickLMPDate.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        LMPDatePickerDialogFragment d = LMPDatePickerDialogFragment.newInstance();
        d.show(getChildFragmentManager(), "dialog");
    }

});

---

There is a problem in your project because you are using the actionBarSherlock which is deprecated... You should take a look at Android Support and use it because the supportFragmentManager is available with it. It's pretty easy to use it, add it in your build.gradle

compile "com.android.support:support-core-utils:25.2.0"

After just extends your activities and fragment with FragmentActivity or Fragment from support. Maybe you will have to make some change because of using sherlock bar

Another thing about your problem is that you called supportFragmentManager from a fragment... you should called

getChildFragmentManager() // because it will be a nested fragment

Hope it's helpful
