# 实现代码 #

普通ListView

package com.example.listviewdemo;
    
    import androidx.appcompat.app.AppCompatActivity;
    
    import android.os.Bundle;
    import android.view.View;
    import android.view.ViewGroup;
    import android.widget.ArrayAdapter;
    import android.widget.BaseAdapter;
    import android.widget.ListView;
    
    public class MainActivity extends AppCompatActivity {
        
    
        private static final String[] str=
                {
        
                        "first","second","third","forth",
                        "fifth"
                };//Define a String array to show the content of ListView
        private ListView lv;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
        
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
            lv=findViewById(R.id.lv);
            lv.setAdapter(new ArrayAdapter<String>(
                    this,android.R.layout.simple_list_item_1,str
            ));
    
        }
    }

单选框：

带有多选框的ListView

多选的附带RadioButton的ListView（单选同理，只需要把

> ListView.CHOICE\_MODE\_MULTIPLE

改为  
ListView.CHOICE\_MODE\_SINGLE
