Question

我创建了自定义Adapter，我已将Arraylist传递给它。但是当我调用此适配器时，我的应用程序崩溃时出现以下错误：

我的自定义适配器代码是：

public class SuerveryAdapter extends BaseAdapter {
    private Activity activity;
    private ArrayList<serveyData> data;

    private static LayoutInflater layoutInflater=null;
    public Resources res;
    serveyData ser_obj;

    public SuerveryAdapter(Activity a, ArrayList d , Resources r) {
        activity = a;
        data = d;
        res = r;
        layoutInflater  =(LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        /* for (serveyData e : data) {
            String NameAndEmail = data.size()+"000"+e.getId() + "," + e.getName()+ "," +e.getDesciption();
            Toast.makeText(activity, NameAndEmail,Toast.LENGTH_SHORT).show();
        }*/
    }

    @Override
    public int getCount() {
        return data.size();
    }

    @Override
    public Object getItem(int position) {
        return data.get(position);
    }

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

    public  class viewHolder{
        public TextView tvId;
        public TextView tvName;

        // public TextView tvDesc;
        public Button select;
      }

      @Override
      public View getView(int position, View convertView, ViewGroup parent) {
          View v1=convertView;
          final  viewHolder holder;
          if (v1==null){
              holder=new viewHolder();
              v1 =layoutInflater.inflate(R.layout.single_item,null);
              holder.tvId=(TextView) v1.findViewById(R.id.tvName);
              holder.tvName=(TextView) v1.findViewById(R.id.textViewName);
              //holder.tvDesc=(TextView) v1.findViewById(R.id.textViewDesc);
              holder.select=(Button) v1.findViewById(R.id.btnDelete) ;

              v1.setTag(holder);
          }
          else {
              holder=(viewHolder)v1.getTag();
          }
          if(data.size()<1){
              holder.tvName.setText("NO Data found");
          }
          else {
              ser_obj=new serveyData();

              ser_obj=(serveyData) data.get(position);
              holder.tvId.setText(ser_obj.getId());
              holder.tvName.setText(ser_obj.getName());
              // holder.tvDesc.setText(ser_obj.getDesciption());
              //Toast.makeText(activity,ser_obj.getId()+ser_obj.getName()+ser_obj.getDesciption(),Toast.LENGTH_SHORT).show();
        }

        return v1;
    }
}

我的主叫代码是

listView =(ListView)findViewById(R.id.slistview);
SuerveryAdapter suerveryAdapter= new SuerveryAdapter(SuerveyUserActivity.this,arrayList,getResources());
listView.setAdapter(suerveryAdapter);

请指导如何摆脱这个问题。

我的自定义listview列表的Xml文件是

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:padding="2dp"
    android:gravity="center_vertical"
    android:layout_height="wrap_content">
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/tvID"
        android:visibility="gone"/>
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/tvName"
        android:layout_margin="13dp" />
    <Button
        android:layout_width="wrap_content"
        android:layout_gravity="center_vertical|right"
        android:layout_height="wrap_content" android:id="@+id/btnDelete"
        android:text="Delete" />
</LinearLayout>

另一个主要listview

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_suervey_user"
    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.abbkr.android2k17_proj.SuerveyUserActivity">
    <ListView
        android:layout_width="321dp"
        android:layout_height="247dp"
        android:id="@+id/slistview"
    />
</LinearLayout>

Answer 1

检查您的Textview ID

  holder.tvId=(TextView) v1.findViewById(R.id.tvName);
  holder.tvName=(TextView) v1.findViewById(R.id.textViewName);

应该是

  holder.tvId=(TextView) v1.findViewById(R.id.tvID);
  holder.tvName=(TextView) v1.findViewById(R.id.tvName);

Answer 2

您将int值设为TextView。然后TextView期望您的资源中的文字具有int值（ser_obj.getId()）。改变这一行：

holder.tvId.setText(ser_obj.getId());

用这个：

holder.tvId.setText(String.valueOf(ser_obj.getId()));

祝你好运。
