Android编程实现带有单选按钮和复选按钮的dialog功能示例

package example.com.myapplication;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog;
import android.content.DialogInterface;
import android.os.bundle;
import android.widget.Toast;
public class MainActivity extends Activity {
  //声明选中项变量
  privatE int SELEctedCityIndex = 0;
  @Override
  public void onCreate(Bundle savedInstanceStatE) {
    super.onCreate(savedInstanceStatE);
    setContentView(R.layout.activity_main);
    //定义城市数组
    final String[] arrayCity = new String[] { "杭州","纽约","威尼斯","北海道" };
    //实例化AlertDialog对话框
    Dialog alertDialog = new AlertDialog.builder(this)
        .settitle("你最喜欢哪个地方？")            //设置标题
        .setIcon(R.mipmap.ic_launcher)        //设置图标
        //设置对话框显示一个单选List，指定默认选中项，同时设置监听事件处理
        .setSingleChoiceItems(arrayCity,new DialogInterface.onClickListener() {
          @Override
          public void onClick(DialogInterface dialog,int which) {
            SELEctedCityIndex = which;        //选中项的索引保存到选中项变量
          }
        })
        //添加取消按钮并增加监听处理
        .setNegativeButton("取消",int which) {
            // TODO Auto-generated method stub
          }
        })
        //添加确定按钮并增加监听处理
        .setPositiveButton("确认",int which) {
            Toast.makeText(getApplication(),arrayCitY[SELEctedCityIndex],Toast.LENGTH_SHORT).show();
          }
        })
        .create();
    alertDialog.show();
  }
}
