Android实现单选与多选对话框的代码

publicvoidmyClick(View view) {

  // 单选对话框

  //singleCheckDialog();

  // 多选对话框

  mulCheckDialog();

 }

 privatevoidmulCheckDialog() {

  AlertDialog.Builder builder =newAlertDialog.Builder(this);

  builder.setTitle("标题")

    .setMultiChoiceItems(items, checkedItems,newDialogInterface.OnMultiChoiceClickListener() {

     @Override

     publicvoidonClick(DialogInterface dialog,intwhich,booleanisChecked) {

     }

    })

    .setPositiveButton("确定",newDialogInterface.OnClickListener() {

     @Override

     publicvoidonClick(DialogInterface dialog,intwhich) {

      StringBuilder reuslt =newStringBuilder();

      for(inti =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",newDialogInterface.OnClickListener() {

     @Override

     publicvoidonClick(DialogInterface dialog,intwhich) {

     }

    }).show();

 }

 privatevoidsingleCheckDialog() {
