（2）MianActivity.java
1 button2.setOnClickListener(new View.OnClickListener() { 2 @Override 3 public void onClick(View v) { 4 AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this) 5 .setTitle("简单列表") 6 .setIcon(R.mipmap.ic_launcher) 7 .setItems(str, new DialogInterface.OnClickListener() { 8 @Override 9 public void onClick(DialogInterface dialog, int which) { 10 info=str[which]; 11 AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this); 12 builder.setPositiveButton("确认", new DialogInterface.OnClickListener() { 13 @Override 14 public void onClick(DialogInterface dialog, int which) { 15 textView.setText(info); 16 } 17 }); 18 builder.setNegativeButton("取消",null); 19 builder.create().show(); 20 } 21 }) 22 23 .create(); 24 alertDialog.show(); 25 26 } 27 });

(1)效果图：点击多选按钮，点击确认，实现显示多选的选项
（2）MainActivity.java
声明的变量：
1 private Button button,button2,button3; 2 private String[] str={"java","xml","Android"}; 3 private String info=""; 4 private TextView textView; 5 private boolean[] isCheck ={false,false,false}; 6 private List<String> list;
初始化：
1 button = (Button) findViewById(R.id.bt); 2 button2 = (Button) findViewById(R.id.bt2); 3 button3 = (Button) findViewById(R.id.bt3); 4 textView = (TextView) findViewById(R.id.tv); 5 list = new ArrayList<String>();
主要代码：
1 button3.setOnClickListener(new View.OnClickListener() { 2 @Override 3 public void onClick(View v) { 4 AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this); 5 //1.设置标题 6 builder.setTitle("多选提示"); 7 //2.调用setIcon()显示图标 8 builder.setIcon(R.mipmap.ic_launcher); 9 //3.设置对话框的内容 10 builder.setMultiChoiceItems(str, isCheck, new DialogInterface.OnMultiChoiceClickListener() { 11 @Override 12 public void onClick(DialogInterface dialog, int which, boolean isChecked) { 13 if (isChecked){ 14 list.add(str[which]); 15 }else{ 16 list.remove(str[which]); 17 } 18 } 19 }); 20 builder.setPositiveButton("确认", new DialogInterface.OnClickListener() { 21 @Override 22 public void onClick(DialogInterface dialog, int which) { 23 textView.setText(list.toString()); 24 } 25 }); 26 27 builder.setNegativeButton("取消", new DialogInterface.OnClickListener() { 28 @Override 29 public void onClick(DialogInterface dialog, int which) { 30 textView.setText(list.toString()); 31 } 32 }); 33 builder.create().show(); 34 } 35 }); 36 37 38 }
