如何使一个微调的警告对话框 [英] How to make an alert dialog with a spinner

问题描述

我知道如何使一个警告对话框，但我需要做一个有微调，这样，当它弹出的人都会有一种选择，因为对发生的事情。有没有人有code与一个微调警告对话框，或知道任何好的教程？

在此先感谢

解决方案

  LayoutInflater李= LayoutInflater.from（上下文）;

                查看promptsView = li.inflate（R.layout.my_dialog_layout，NULL）;

                AlertDialog.Builder alertDialogBu​​ilder =新AlertDialog.Builder（上下文）;

                alertDialogBu​​ilder.setView（promptsView）;

                //设置对话框消息

                alertDialogBu​​ilder.setTitle（我的对话......）;
                alertDialogBu​​ilder.setIcon（R.drawable.ic_launcher）;
                //创建警报对话框
                最终AlertDialog alertDialog = alertDialogBu​​ilder.create（）;

                最后的微调mSpinner =（微调）promptsView
                        .findViewById（R.id.mySpinner）;
                最终按钮mButton =（按钮）promptsView
                        .findViewById（R.id.myButton）;

                //从my_dialog_layout以类似的方式参考UI元素

                mSpinner.setOnItemSelectedListener（新OnSpinnerItemClicked（））;

                // 展示下
                alertDialog.show（）;
                alertDialog.setCanceledOnTouchOutside（假）;
 

其中

my_dialog_layout 是你包含了微调的弹出式布局的 mySpinner

编辑：

 公共类OnSpinnerItemClicked工具OnItemSelectedListener {

        @覆盖
        公共无效onItemSelected（适配器视图＆LT;＆GT;父，
                视图中查看，INT POS，长I​​D）{
            Toast.makeText（parent.getContext（），已点击：+
                    parent.getItemAtPosition（POS）的ToString（），Toast.LENGTH_LONG）.show（）;


        }

        @覆盖
        公共无效onNothingSelected（适配器视图父）{
            // 没做什么。
        }
    }
 

I know how to make an alert dialog but I need to make one with a spinner so that when it pops up the person will have an option as to what happens. Does anyone have the code for an alert dialog with a spinner or know any good tutorials?

Thanks in advance

解决方案

                LayoutInflater li = LayoutInflater.from(context);

                View promptsView = li.inflate(R.layout.my_dialog_layout, null);

                AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(context);

                alertDialogBuilder.setView(promptsView);

                // set dialog message

                alertDialogBuilder.setTitle("My Dialog..");
                alertDialogBuilder.setIcon(R.drawable.ic_launcher);
                // create alert dialog
                final AlertDialog alertDialog = alertDialogBuilder.create();

                final Spinner mSpinner= (Spinner) promptsView
                        .findViewById(R.id.mySpinner);
                final Button mButton = (Button) promptsView
                        .findViewById(R.id.myButton);

                // reference UI elements from my_dialog_layout in similar fashion

                mSpinner.setOnItemSelectedListener(new OnSpinnerItemClicked());

                // show it
                alertDialog.show();
                alertDialog.setCanceledOnTouchOutside(false);

where

my_dialog_layout is the popup layout which you contains the Spinner mySpinner

EDIT :

public class OnSpinnerItemClicked implements OnItemSelectedListener {

        @Override
        public void onItemSelected(AdapterView<?> parent,
                View view, int pos, long id) {
            Toast.makeText(parent.getContext(), "Clicked : " +
                    parent.getItemAtPosition(pos).toString(), Toast.LENGTH_LONG).show();


        }

        @Override
        public void onNothingSelected(AdapterView parent) {
            // Do nothing.
        }
    }
