需要建一个menu  
xml布局如下：

<?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="match_parent"
     tools:context="com.example.lyp1020k.lv.MainActivity"
     android:orientation="vertical">
     
     <Button
     android:id="@+id/button1"
     android:text="列表框"
     android:onClick="showList"
     android:layout_width="match_parent"
     android:layout_height="wrap_content" />
     
     <Button
     android:id="@+id/button2"
     android:text="单选列表"
     android:onClick="showSingleAlertDialog"
     android:layout_width="match_parent"
     android:layout_height="wrap_content" />
     
     <Button
     android:id="@+id/button3"
     android:text="多选按钮"
     android:onClick="showMutilAlertDialog"
     android:layout_width="match_parent"
     android:layout_height="wrap_content" />
     
    </LinearLayout>

Java代码如下：

import android.content.DialogInterface;
    import android.support.v7.app.AlertDialog;
    import android.support.v7.app.AppCompatActivity;
    import android.os.Bundle;
    import android.view.Menu;
    import android.view.View;
    import android.widget.Button;
    import android.widget.Toast;
     
    public class MainActivity extends AppCompatActivity { 
     
     private AlertDialog alertDialog1; //信息框
     private AlertDialog alertDialog2; //单选框
     private AlertDialog alertDialog3; //多选框
     
     private Button button1;
     private Button button2;
     private Button button3;
     
     @Override
     protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState);
     setContentView(R.layout.activity_main);
     init();
     }
     
     public void init(){ 
     button1 = (Button) findViewById(R.id.button1);
     button2 = (Button) findViewById(R.id.button2);
     button3 = (Button) findViewById(R.id.button3);
     }
     
     @Override
     public boolean onCreateOptionsMenu(Menu menu) { 
     getMenuInflater().inflate(R.menu.mian, menu);
     return true;
     }
     
     public void showList(View view){ 
     final String[] items = { "列表1", "列表2", "列表3", "列表4"};
     AlertDialog.Builder alertBuilder = new AlertDialog.Builder(this);
     alertBuilder.setTitle("这是列表框");
     alertBuilder.setItems(items, new DialogInterface.OnClickListener() { 
     @Override
     public void onClick(DialogInterface dialogInterface, int i) { 
     Toast.makeText(MainActivity.this, items[i], Toast.LENGTH_SHORT).show();
     alertDialog1.dismiss();
     }
     });
     alertDialog1 = alertBuilder.create();
     alertDialog1.show();
     }
     
     public void showSingleAlertDialog(View view){ 
     final String[] items = { "单选1", "单选2", "单选3", "单选4"};
     AlertDialog.Builder alertBuilder = new AlertDialog.Builder(this);
     alertBuilder.setTitle("这是单选框");
     alertBuilder.setSingleChoiceItems(items, 0, new DialogInterface.OnClickListener() { 
     @Override
     public void onClick(DialogInterface dialogInterface, int i) { 
     Toast.makeText(MainActivity.this, items[i], Toast.LENGTH_SHORT).show();
     }
     });
     
     alertBuilder.setPositiveButton("确定", new DialogInterface.OnClickListener() { 
     @Override
     public void onClick(DialogInterface dialogInterface, int i) { 
     alertDialog2.dismiss();
     }
     });
     
     alertBuilder.setNegativeButton("取消", new DialogInterface.OnClickListener() { 
     @Override
     public void onClick(DialogInterface dialogInterface, int i) { 
     alertDialog2.dismiss();
     }
     });
     
     alertDialog2 = alertBuilder.create();
     alertDialog2.show();
     }
     
     public void showMutilAlertDialog(View view){ 
     final String[] items = { "多选1", "多选2", "多选3", "多选4"};
     AlertDialog.Builder alertBuilder = new AlertDialog.Builder(this);
     alertBuilder.setTitle("这是多选框");
     /** *第一个参数:弹出框的消息集合，一般为字符串集合 * 第二个参数：默认被选中的，布尔类数组 * 第三个参数：勾选事件监听 */
     alertBuilder.setMultiChoiceItems(items, null, new DialogInterface.OnMultiChoiceClickListener() { 
     @Override
     public void onClick(DialogInterface dialogInterface, int i, boolean isChecked) { 
     if (isChecked){ 
      Toast.makeText(MainActivity.this, "选择" + items[i], Toast.LENGTH_SHORT).show();
     }else { 
      Toast.makeText(MainActivity.this, "取消选择" + items[i], Toast.LENGTH_SHORT).show();
     }
     }
     });
     alertBuilder.setPositiveButton("确定", new DialogInterface.OnClickListener() { 
     @Override
     public void onClick(DialogInterface dialogInterface, int i) { 
     alertDialog3.dismiss();
     }
     });
     
     alertBuilder.setNegativeButton("取消", new DialogInterface.OnClickListener() { 
     @Override
     public void onClick(DialogInterface dialogInterface, int i) { 
     alertDialog3.dismiss();
     }
     });
     
     
     alertDialog3 = alertBuilder.create();
     alertDialog3.show();
     }
    }
