如何为列表视图创建自定义适配器？ 获取RessourceNotFoundException
[英]How to create a custom adapter for a listview? Getting RessourceNotFoundException
问题描述
I am trying to make a custom adapter for my listview, but I keep getting a RessourceNotFoundException on the same line. 
我正在尝试为我的列表视图创建一个自定义适配器，但是我在同一行上始终收到RessourceNotFoundException。
Firstly, here is my adapter class code: 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;
}
}
And here is the xml for the view, containing the listview: 这是该视图的xml，其中包含listview：
<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:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context="com.mobileplatformexam.activities.CreateProgramActivity"
android:id="@+id/relativeLayoutCreateProgram">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Add training pass"
android:id="@+id/btn_add_trainingpass"
android:layout_alignParentTop="true"

android:onClick="addTrainingPass"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="\?"

android:layout_alignParentTop="true"

<Button

android:layout_above="@+id/btn_create_program"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_below="@+id/btn_add_trainingpass" />
</RelativeLayout>
And the xml file with the item layout for the above listview: 以及上面列表视图的项目布局的xml文件：
<?xml version="1.0" encoding="utf-8"?>

android:layout_alignStart="@+id/trainingpass_addexercise_button" />
</RelativeLayout>
</LinearLayout>
And this is the code for setting the adapter in my activity (extends Activity) 这是用于在我的活动中设置适配器的代码（扩展了Activity）
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);
The error i am getting is this: 我得到的错误是这样的：
12661-12661/com.mobileplatformexam E/AndroidRuntime﹕ FATAL EXCEPTION: main android.content.res.Resources$NotFoundException: Resource ID #0x7f04001a at android.content.res.Resources.getValue(Resources.java:1019) at android.content.res.Resources.loadXmlResourceParser(Resources.java:2107) at android.content.res.Resources.getLayout(Resources.java:858) at android.view.LayoutInflater.inflate(LayoutInflater.java:394) at android.view.LayoutInflater.inflate(LayoutInflater.java:352) at com.mobileplatformexam.Adapters.CreateProgramAdapter.getView(CreateProgramAdapter.java:56) at android.widget.AbsListView.obtainView(AbsListView.java:2466) at android.widget.ListView.measureHeightOfChildren(ListView.java:1244) at android.widget.ListView.onMeasure(ListView.java:1155) at android.view.View.measure(View.java:12807) at android.widget.RelativeLayout.measureChildHorizontal(RelativeLayout.java:642) at android.widget.RelativeLayout.onMeasure(RelativeLayout.java:424) at android.view.View.measure(View.java:
The error refers to line 56 in my adapterclass, which is the following line: 该错误涉及我的adapterclass中的第56行，即以下行：
convertView = inflater.inflate(R.layout.adapter_createprogram_trainingpasses_item, null);
I really can't seem to find out what may be wrong with the code, so I hope someone can help me out. 我似乎似乎真的找不到代码有什么问题，所以我希望有人可以帮助我。
Thanks 谢谢

Thanks to JafarKhQ, I solved the problem. 感谢JafarKhQ，我解决了这个问题。 By changing the layout "adapter_createprogram_trainingpasses_item .xml" to the following, it worked: 通过将布局“ adapter_createprogram_trainingpasses_item .xml”更改为以下内容，它可以工作：
