android开发中实现单选与多选对话框的代码非常简单，具体代码如下所示：

public void myClick(View view) {
  // 单选对话框
  //singlecheckDialog();
  // 多选对话框
  mulcheckDialog();
 }
 private void mulcheckDialog() {
  AlertDialog.builder builder = new AlertDialog.builder(this);
  builder.settitle("标题")
    .setMultiChoiceItems(items,checkedItems,new DialogInterface.onMultiChoiceClickListener() {
     @Override
     public void onClick(DialogInterface dialog,int which,Boolean ischecked) {
     }
    })
    .setPositiveButton("确定",new DialogInterface.onClickListener() {
     @Override
     public void onClick(DialogInterface dialog,int which) {
      StringBuilder reuslt = new StringBuilder();
      for (int i = 0; i < items.length; i++) {
       if (checkedItems[i]) {
        reuslt.append(items[i]).append(" ");
       }
      }
      Toast.makeText(MainActivity.this,"选择了" + reuslt.toString(),Toast.LENGTH_SHORT).show();
     }
    })
    .setNegativeButton("取消",int which) {
     }
    }).show();
 }
 private void singlecheckDialog() {
  AlertDialog.builder builder = new AlertDialog.builder(this);
  builder.settitle("标题")
    .setSingleChoiceItems(items,-1,int which) {
      String itemStr = items[which];
      Toast.makeText(MainActivity.this,"选择了" + itemStr,Toast.LENGTH_SHORT).show();
      // 关闭对话框
      //dialog.dismiss();
     }
    })
    .setPositiveButton("确定",int which) {
     }
    })
    .setNegativeButton("取消",int which) {
     }
    }).show();
 }
