【问题描述】：

我正在尝试为我的列表视图制作一个自定义适配器，但我一直在同一行收到 RessourceNotFoundException。

首先，这是我的适配器类代码：

public class CreateProgramAdapter extends BaseAdapter 

    private final LayoutInflater inflater;
    private ArrayList<TrainingPass> trainingPasses;
    private List<TrainingPass> items;
    private int layoutResourceId;
    private Context context;

    public CreateProgramAdapter(Context context, List<TrainingPass> items) 
        this.context = context;
        this.items = items;
        inflater = LayoutInflater.from(this.context);
    

    @Override
    public int getCount() 
        return items.size();
    

    @Override
    public Object getItem(int position) 
        return items.get(position);
    

    @Override
    public long getItemId(int position) 
        return 0;
    

    @Override
    public View getView(int position, View convertView, ViewGroup parent) 
        View row = convertView;
        TrainingPassHolder holder;

        if(convertView == null) 
            convertView = inflater.inflate(R.layout.adapter_createprogram_trainingpasses_item, null);
            holder = new TrainingPassHolder();
            convertView.setTag(holder);
         else 
            holder = (TrainingPassHolder) convertView.getTag();
        


        holder.trainingPass = this.items.get(position);
        holder.trainingPassRelativeLayout = (RelativeLayout) row.findViewById(R.id.trainingpass_item_relativelayout);
        holder.headlineTxt = (TextView) row.findViewById(R.id.trainingpass_headline);
        holder.setNoTxt = (TextView) row.findViewById(R.id.txt_trainingpass_setno);
        holder.showHideIcon = (ImageView) row.findViewById(R.id.trainingpass_showhide_imageview);
        holder.exerciseSearchField = (EditText) row.findViewById(R.id.trainingpass_exercise_searchfield);
        holder.repsTextField = (EditText) row.findViewById(R.id.trainingpass_reps_txtfield);
        holder.addSetButton = (Button) row.findViewById(R.id.add_set_button);
        holder.addExerciseButton = (Button) row.findViewById(R.id.trainingpass_addexercise_button);
        holder.setsListView = (ListView) row.findViewById(R.id.trainingpass_sets_listview);
        holder.exercisesListView = (ListView) row.findViewById(R.id.trainingpass_exercises_listview);

        holder.trainingPassRelativeLayout.setTag(holder.trainingPass);
        holder.headlineTxt.setTag(holder.trainingPass);
        holder.setNoTxt.setTag(holder.trainingPass);
        holder.showHideIcon.setTag(holder.trainingPass);
        holder.exerciseSearchField.setTag(holder.trainingPass);
        holder.repsTextField.setTag(holder.trainingPass);
        holder.addSetButton.setTag(holder.trainingPass);
        holder.addExerciseButton.setTag(holder.trainingPass);
        holder.setsListView.setTag(holder.trainingPass);
        holder.exercisesListView.setTag(holder.trainingPass);

        setupItems(holder);

        return convertView;
    

    private void setupItems(TrainingPassHolder trainingPassHolder) 
        // TODO: set default values for items

    

    public static class TrainingPassHolder 
        TrainingPass    trainingPass;
        RelativeLayout  trainingPassRelativeLayout;
        TextView        headlineTxt;
        TextView        setNoTxt;
        ImageView       showHideIcon;
        EditText        exerciseSearchField;
        EditText        repsTextField;
        Button          addSetButton;
        Button          addExerciseButton;
        ListView        setsListView;
        ListView        exercisesListView;
    

这是视图的 xml，包含列表视图：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_
    android:layout_ android:paddingLeft="@dimen/activity_horizontal_margin"

    android:paddingBottom="@dimen/activity_vertical_margin"
    tools:context="com.mobileplatformexam.activities.CreateProgramActivity"
    android:id="@+id/relativeLayoutCreateProgram">


    <Button
        android:layout_
        android:layout_
        android:text="Add training pass"
        android:id="@+id/btn_add_trainingpass"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_toLeftOf="@+id/btn_add_trainingpass_help"
        android:layout_toStartOf="@+id/btn_add_trainingpass_help"
        android:onClick="addTrainingPass"/>

    <Button
        android:layout_
        android:layout_
        android:text="\?"
        android:id="@+id/btn_add_trainingpass_help"
        android:layout_alignParentTop="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true"
        android:onClick="addTrainingPassHelp"/>

    <Button
        android:layout_
        android:layout_
        android:text="Create program"
        android:id="@+id/btn_create_program"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_alignRight="@+id/btn_add_trainingpass_help"
        android:layout_alignEnd="@+id/btn_add_trainingpass_help"
        android:onClick="createProgram"/>

    <ListView
        android:layout_
        android:layout_
        android:id="@+id/listView_trainingpasses"
        android:layout_above="@+id/btn_create_program"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_below="@+id/btn_add_trainingpass" />


</RelativeLayout>

    </RelativeLayout>
</LinearLayout>

这是在我的活动中设置适配器的代码（扩展活动）

 ArrayList<TrainingPass> trainingPasses = new ArrayList<TrainingPass>();

        TrainingPass trainingPass = new TrainingPass();
        trainingPass.setTrainingPassName("wefwef");

        TrainingPass trainingPass2 = new TrainingPass();
        trainingPass.setTrainingPassName("rwefhtr");

        trainingPasses.add(trainingPass);
        trainingPasses.add(trainingPass2);

        ListView trainingPassesListView = (ListView)findViewById(R.id.listView_trainingpasses);
        CreateProgramAdapter createProgramAdapter = new CreateProgramAdapter(CreateProgramActivity.this, trainingPasses);
        trainingPassesListView.setAdapter(createProgramAdapter);

我得到的错误是：

12661-12661/com.mobileplatformexam E/AndroidRuntime: FATAL EXCEPTION: main android.content.res.Resources$NotFoundException：资源 ID #0x7f04001a 在 android.content.res.Resources.getValue(Resources.java:1019) 在 android.content.res.Resources.loadXmlResourceParser(Resources.java:2107) 在 android.content.res.Resources.getLayout(Resources.java:858) 在 android.view.LayoutInflater.inflate(LayoutInflater.java:394) 在 android.view.LayoutInflater.inflate(LayoutInflater.java:352) 在 com.mobileplatformexam.Adapters.CreateProgramAdapter.getView(CreateProgramAdapter.java:56) 在 android.widget.AbsListView.obtainView(AbsListView.java:2466) 在 android.widget.ListView.measureHeightOfChildren(ListView.java:1244) 在 android.widget.ListView.onMeasure(ListView.java:1155) 在 android.view.View.measure(View.java:12807) 在 android.widget.RelativeLayout.measureChildHorizo​​ntal(RelativeLayout.java:642) 在 android.widget.RelativeLayout.onMeasure(RelativeLayout.java:424) 在 android.view.View.measure(View.java:12807) 在 android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:4698) 在 android.widget.FrameLayout.onMeasure(FrameLayout.java:293) 在 android.view.View.measure(View.java:12807) 在 android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:4698) 在 android.support.v7.internal.widget.ActionBarOverlayLayout.onMeasure(ActionBarOverlayLayout.java:453) 在 android.view.View.measure(View.java:12807) 在 android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:4698) 在 android.widget.FrameLayout.onMeasure(FrameLayout.java:293) 在 android.view.View.measure(View.java:12807) 在 android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:4698) 在 android.widget.LinearLayout.measureChildBeforeLayout(LinearLayout.java:1399) 在 android.widget.LinearLayout.measureVertical(LinearLayout.java:690) 在 android.widget.LinearLayout.onMeasure(LinearLayout.java:583) 在 android.view.View.measure(View.java:12807) 在 android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:4698) 在 android.widget.FrameLayout.onMeasure(FrameLayout.java:293) 在 com.android.internal.policy.impl.PhoneWindow$DecorView.onMeasure(PhoneWindow.java:2218) 在 android.view.View.measure(View.java:12807) 在 android.view.ViewRootImpl.performTraversals(ViewRootImpl.java:1068) 在 android.view.ViewRootImpl.handleMessage(ViewRootImpl.java:2452) 在 android.os.Handler.dispatchMessage(Handler.java:99) 在 android.os.Looper.loop(Looper.java:137) 在 android.app.ActivityThread.main(ActivityThread.java:4476) 在 java.lang.reflect.Method.invokeNative(Native Method) 在 java.lang.reflect.Method.invoke(Method.java:511) 在 com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:816) 在 com.android.internal.os.ZygoteInit.main(ZygoteInit.java:583) 在 dalvik.system.NativeStart.main(Native Method)

错误是指我的适配器类中的第 56 行，即以下行：

   convertView = inflater.inflate(R.layout.adapter_createprogram_trainingpasses_item, null);

我似乎真的无法找出代码可能有什么问题，所以我希望有人能帮助我。

谢谢

【问题讨论】：

将convertView = inflater.inflate(R.layout.adapter_createprogram_trainingpasses_item, null); 更改为convertView = inflater.inflate(R.layout.adapter_createprogram_trainingpasses_item, parent , false);

谢谢，但不幸的是我仍然得到完全相同的错误。

“adapter_createprogram_trainingpasses_item.xml”在哪个目录下？

adapter_createprogram_trainingpasses_item.xml 当前与其余布局 xml 文件位于同一目录中。

最后一次尝试。到您的项目布局并尝试通过删除所有 textCorlor/bgColor ... 来简化它，甚至删除布局子项（TextView Buttons listView ??）只需保留在 FreamLyout

【参考方案1】：

感谢 JafarKhQ，我解决了这个问题。 通过将布局“adapter_createprogram_trainingpasses_item .xml”更改为以下内容，它起作用了：
