getSupportFragmentManager（）未定义

我收到以下错误： “我的片段文件中的类型new View.OnClickListener（）{}” 未定义方法getSupportFragmentManager（）下方。

我有通过ABS引用的兼容性库以及适当的导入。我重新安装了带有兼容性库的ABS库，清理了项目，重新启动了Eclipse，但没有任何工作。

基本上，我试图让片段通过对话框片段显示日期选择器。选择日期后，必须将其返回到片段，以便根据该日期计算信息。

这是我片段的代码：

package com.owentech.abstabsviewpager;

import android.app.Activity;
import android.app.Dialog;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.Toast;
import android.support.v4.app.DialogFragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentTransaction;
import com.actionbarsherlock.app.SherlockFragment;

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

    });

    return view;
}

public Dialog onCreateDialog(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    return null;
}

}

以下是Dialog Fragment的代码：

package com.owentech.abstabsviewpager;

import android.app.Dialog;
import android.os.Bundle;
import android.widget.DatePicker;
import android.app.DatePickerDialog;

public class LMPDatePickerDialogFragment extends ObstetricsFragment1 implements DatePickerDialog.OnDateSetListener {

static LMPDatePickerDialogFragment newInstance() {
    LMPDatePickerDialogFragment d = new LMPDatePickerDialogFragment();
    return d;
}

private int mLMPYear;
private int mLMPMonth;
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;
    mLMPMonth = month;
    mLMPDay = day;
}
}

最后，这是我的活动的代码：

package com.owentech.abstabsviewpager;

import android.content.Context;
import android.content.Intent;
import android.net.Uri;

import android.support.v4.app.Fragment;

        return true;
    case android.R.id.home:
        // App icon in action bar clicked; go home
        Intent intent = new Intent(this, Home.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        startActivity(intent);

通过调用对话框的活动扩展FragmentActivity

，您将摆脱此问题 
public class ObstetricsFragment1 extends FragmentActivity{

这是支持库所固有的，如DIALOG SPECS和SUPPORT LIBRARY SPECS

中所示

答案 1 :(得分：9)

尝试将代码更改为：

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;
}

答案 2 :(得分：4)

我对Marco的答案做了一个分歧，看看他实际建议改变的是什么：只是

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

到

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

答案 3 :(得分：3)

如果有人使用SherlockActivity代替SherlockFragment，只需将活动延伸至SherlockFragmentActivity。

答案 4 :(得分：2)

我在加载课程项目时遇到了类似问题（https://developer.android.com/training/multiple-threads）。

要解决这个问题，我必须添加一个外部jar（sdk / extras / android / support / v4 / android-support-v4.jar）。

希望这有帮助。

答案 5 :(得分：1)

您需要从SherlockDialogFragment扩展ObstetricsFragment1。

答案 6 :(得分：0)

要在片段调用FragmentManager中获取getChildFragmentManager()。 见this.

更改此

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

});

到

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

});

答案 7 :(得分：-1)

您的项目中存在问题，因为您正在使用不推荐使用的actionBarSherlock ... 您应该查看Android Support并使用它，因为supportFragmentManager随其可用。 它很容易使用，将它添加到build.gradle中

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

刚刚扩展您的活动并使用FragmentActivity或Fragment片段进行支持。 也许你因为使用sherlock bar而必须做出一些改变

您的问题的另一个问题是您从片段中调用了supportFragmentManager ...您应该调用

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

希望它有用
