具有自定义布局的用户自定义适配器，可将删除按钮附加到列表视图中的每个项目

尝试此代码：

CustomAdapter

public class ListAdapter extends ArrayAdapter<String> {

private int resourceLayout;
private Context mContext;
ListInterFace interface;

public ListAdapter(Context context,int resource,List<String> 
   items,ListInterFace interface) {
    super(context,resource,items);
    this.resourceLayout = resource;
    this.mContext = context;
    this.interface=interface;
}

@Override
public View getView(int position,View convertView,ViewGroup parent) {

    View v = convertView;

    if (v == null) {
        LayoutInflater vi;
        vi = LayoutInflater.from(mContext);
        v = vi.inflate(resourceLayout,null);
    }

    String value= getItem(position);

    if (value!= null) {
        TextView tt1 = (TextView) v.findViewById(R.id.dummytext);
        Button cancel_click=v.findViewById(R.id.cancel_click);

        if (tt1 != null) {
            tt1.setText(value);
        }
       //remove item on button click
        cancel_click.setOnClickListener(new  View.OnClickListener(){
        @Override
        public void onClick(View view){
            interface.removeItem(position);
        }
    })
    }

    return v;
}

}

  

R.layout.itemlistrow定义ListView的行。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    tools:context=".MainActivity">

  <RelativeLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content">
     <TextView
         android:id="@+id/dummytext"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:text="Dummy"
         android:textColor="@android:color/black"
         android:textSize="18sp"
         android:padding="5dp"/>
     <ImageView 
          android:id="@+id/cancel_click"
         android:layout_width="20dp"
         android:layout_height="20dp"
         android:src="@mipmap/cancel"
       android:layout_alignParentRight="true"
         android:layout_margin="5dp"/>
  </RelativeLayout>
</LinearLayout>

  

在MainActivity中定义这样的ListView，

ListView yourListView = (ListView) findViewById(R.id.itemListView);

// get data from the table by the ListAdapter
 ListAdapter customAdapter = new ListAdapter(this,R.layout.itemlistrow,myList,new ListInterFace () {
                    @Override
                      public void removeItem( int position) {
                      myList.remove(position);
                    customAdapter .notifyDataSetChanged();
                 });

 yourListView .setAdapter(customAdapter);

InterFace

public interface ListInterFace  {
   void removeItem(int position);
}
