Android应用程序在片段中创建Listview时崩溃

每次我移动到此活动时，我的应用程序都会崩溃。我认为问题在于在片段中创建和填充ListView

public static class PlaceholderFragment extends Fragment {

    public PlaceholderFragment() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_list_routines,
                container, false);

        ListView list = (ListView)rootView.findViewById(R.id.listview_routines);
        populateListView(list);
        return rootView;
    }

    private void populateListView(ListView list){


        String[] items = null;
        int work = 1;
        switch(work){

            case 1:
                items = new String[]{"Dumbbell Curls","Dumbbell Kickbacks","Bench Dips","Dumbbell Hammer Curls", "Diamond Pushups", "Dumbbell Flyes"};
                break;
            case 2:
                items = new String[]{"Squats","Plank","Lunges","Leg Raises","Calf Raises","Crunches"};
                break;
            case 3:
                items = new String[]{"Dumbbell Rows","Superman","Arnold Press","Dumbbell Reverse Flyes","Lateral Raises","Pull-Up"};
                break;
        }

        ArrayAdapter<String> adapter = new ArrayAdapter<String>(
                getActivity(),
                R.layout.routine_items,
                items
                );

        list.setAdapter(adapter);


    }
}

这是我的fragment_list_routines.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.tutorial.ListRoutinesActivity$PlaceholderFragment" >

<ListView
    android:id="@+id/listview_routines"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    />

几个小时都找不到解决方案。还是一个android新手呵呵

看起来你的应用程序崩溃了：

原因：java.lang.NoSuchMethodException:arms\u and\u cost[class android.view.view]

如果要使用此方法，则需要定义此方法

似乎您的XML正在通过按钮引用此方法

用于id为“btn\u arms”的视图类android.widget.Button上的onClick处理程序

在XML中找到此引用，然后删除此引用并在代码中定义OnClickListener，或者将此方法添加到活动中：

 public void arms_and_chest(View view){
     // ... Operations here

 }

你能发布崩溃日志吗？什么是

私有静态上下文列表\u上下文？for？找不到方法arms_和_-cost（View）@Blackbelt别介意，我以前在fragment类中引用过活动，现在，我使用getActivity（）方法。你在哪里定义了btn_-arms按钮？谢谢！它现在可以工作了：）错误在于从xml到类方法的引用的拼写错误。哈哈哈
