Android中的行布局未膨胀

我有个问题。我几周前开始学习Android。我正在尝试为列表创建适配器。但这些名单根本没有出现。你知道为什么吗？这些项目是对象类型的动词。这是我的密码：

///我的主要活动///

public class Verbs extends Activity {
private ListView listViewVerbs;

@Override
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_verbs);

    //instantiate Verb
    Verb[] VerbData=new Verb[3];

    VerbData[0] = new Verb("machen","mache","machen","mache","machen","mache","machen");
    VerbData[1] = new Verb("machen","mache","machen","mache","machen","mache","machen");
    VerbData[2] = new Verb("machen","mache","machen","mache","machen","mache","machen");

    //pass data to adapter

    VerbAdapter adapter = new VerbAdapter(this,R.layout.row_verbs,VerbData);
    listViewVerbs = (ListView)findViewById(R.id.list);
    listViewVerbs.setAdapter(adapter);

    listViewVerbs.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

            String wasClicked = view.findViewById(R.id.nameVerb).toString();
            Toast.makeText(Verbs.this,
                    "You clicked: " + wasClicked, Toast.LENGTH_LONG)
                    .show();
        }
    });
}

}

//适配器

public class VerbAdapter extends ArrayAdapter<Verb>{

Context mContext;
int layoutResourceId;
Verb data[] = null;

public VerbAdapter(Context mContext, int layoutResourceId, Verb[] data){
    super(mContext, layoutResourceId, data);
    this.mContext = mContext;
    this.layoutResourceId =layoutResourceId;
    this.data = data;
}

@Override
public View getView(int position, View convertView, ViewGroup parent){
    if (convertView == null){
        LayoutInflater inflater = ((Activity) mContext).getLayoutInflater();
        convertView = inflater.inflate(layoutResourceId,parent, false);
    }
    TextView textView0 = (TextView) convertView.findViewById(R.id.nameVerb);
    TextView textView1 = (TextView) convertView.findViewById(R.id.firstpersonsg);
    TextView textView2 = (TextView) convertView.findViewById(R.id.firstpersonpl);
    TextView textView3 = (TextView) convertView.findViewById(R.id.secondpersonsg);
    TextView textView4 = (TextView) convertView.findViewById(R.id.secondpersonpl);
    TextView textView5 = (TextView) convertView.findViewById(R.id.thirdpersonsg);
    TextView textView6 = (TextView) convertView.findViewById(R.id.thirdpersonpl);

    Verb verb = data[position];
    textView0.setText(verb.verbname);
    textView1.setText(verb.fpersg);
    textView2.setText(verb.fperspl);
    textView3.setText(verb.sperssg);
    textView4.setText(verb.sperspl);
    textView5.setText(verb.tperssg);
    textView6.setText(verb.tperspl);
    return convertView;
}

}

公共类VerbAdapter扩展了ArrayAdapter{
语境；
国际布局资源；
动词数据[]=null；
公共VerbAdapter（上下文mContext、int-layoutResourceId、谓词[]数据）{
super（mContext、layoutResourceId、data）；
this.mContext=mContext；
this.layoutResourceId=layoutResourceId；
这个数据=数据；
}
@凌驾
公共视图getView（int位置、视图转换视图、视图组父视图）{
if（convertView==null）{
LayoutFlater充气器=（（活动）mContext.getLayoutFlater（）；
convertView=充气机。充气（layoutResourceId，父项，false）；
}
TextView textView0=（TextView）convertView.findViewById（R.id.nameVerb）；
TextView textView1=（TextView）convertView.findViewById（R.id.firstpersonsg）；
TextView textView2=（TextView）convertView.findViewById（R.id.firstpersonpl）；
TextView textView3=（TextView）convertView.findViewById（R.id.secondpersonsg）；
TextView textView4=（TextView）convertView.findViewById（R.id.secondpersonpl）；
TextView textView5=（TextView）convertView.findViewById（R.id.thirdpersonsg）；
TextView textView6=（TextView）convertView.findViewById（R.id.thirdpersonpl）；
动词=数据[位置]；
textView0.setText（动词.verbname）；
textView1.setText（动词.fpersg）；
textView2.setText（动词.fperspl）；
textView3.setText（动词.sperssg）；
textView4.setText（动词.sperspl）；
textView5.setText（动词.tperssg）；
textView6.setText（动词.tperspl）；
返回视图；
}
}

------以及两个名为activity_verbs的XML文件，其中声明了列表和row_verbs，其中声明了每个项的布局-----

row_verbs.xml------

另一个是activity_verbs.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="${relativePackage}.${activityClass}"
    android:layout_width="match_parent"
    android:layout_height="match_parent">


    <TextView
        android:id="@+id/textView2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@string/app_name"
        android:textSize="20sp"
        android:padding="10dp"
        android:background="#7663d5"
        android:textColor="#f8f8f8"
        android:textStyle="bold"/>

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/lessonId"
        android:layout_below="@+id/textView2"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:background="#292929"
        android:textColor="#f0f0f0"
        android:padding="10dp"/>

    <ListView
        android:id="@+id/list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_below="@+id/lessonId"/>

</RelativeLayout>

我只做了一次更改就复制了您的代码： 我搬走了

  tools:context="${relativePackage}.${activityClass}"

从活动中，它对我来说就像一个符咒：

我已将我的测试项目和您的代码上载到DropBox，请随意下载：

问题结构非常好，干得好
