Android实现单选与多选对话框的代码

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", new DialogInterface.OnClickListener() {
     @Override
     public void onClick(DialogInterface dialog, int which) {
     }
    }).show();
 }
 private void singleCheckDialog() {
  AlertDialog.Builder builder = new AlertDialog.Builder(this);
  builder.setTitle("标题")
    .setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener() {
     @Override
     public void onClick(DialogInterface dialog, 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", new DialogInterface.OnClickListener() {
     @Override
     public void onClick(DialogInterface dialog, int which) {
     }
    })
    .setNegativeButton("取消", new DialogInterface.OnClickListener() {
     @Override
     public void onClick(DialogInterface dialog, int which) {
     }
    }).show();
 }
