Android控件之AlertDialog-单选、多选信息列表弹出框

1、AlertDialog的信息列表、单选、多选对话框简介

上一遍简单介绍了一个信息提示框，下面一次介绍信息列表对话框、单选对话框、多选对话框，具体效果如下







2、xml布局文件

布局文件只是几个按钮，并且为其绑定了点击事件，点击按钮后弹出对话框

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<Button
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignRight="@+id/button1"
android:layout_below="@+id/button1"
android:onClick="showListAlertDialog"
android:text="信息列表框" />
<Button
android:id="@+id/button3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/button2"
android:layout_alignParentRight="true"
android:layout_below="@+id/button2"
android:onClick="showSingleAlertDialog"
android:text="单选列表" />
<Button
android:id="@+id/button4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/button3"
android:layout_alignParentRight="true"
android:layout_below="@+id/button3"
android:onClick="showMutilAler<span style="font-family: Arial, Helvetica, sans-serif;">tDialog"</span>
android:text="多选按钮" />

</RelativeLayout>

3、java代码

package com.example.alertdialog;

import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}

// 信息列表提示框
private AlertDialog alertDialog1;
public void showListAlertDialog(View view){
final String[] items = {"Struts2","Spring","Hibernate","Mybatis","Spring MVC"};
AlertDialog.Builder alertBuilder = new AlertDialog.Builder(this);
alertBuilder.setTitle("java EE 常用框架");
alertBuilder.setItems(items, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface arg0, int index) {
Toast.makeText(MainActivity.this, items[index], Toast.LENGTH_SHORT).show();
alertDialog1.dismiss();
}
});
alertDialog1 = alertBuilder.create();
alertDialog1.show();
}

// 单选提示框
private AlertDialog alertDialog2;
public void showSingleAlertDialog(View view){
final String[] items = {"Struts2","Spring","Hibernate","Mybatis","Spring MVC"};
AlertDialog.Builder alertBuilder = new AlertDialog.Builder(this);
alertBuilder.setTitle("java EE 常用框架");
alertBuilder.setSingleChoiceItems(items, 0, new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface arg0, int index) {
Toast.makeText(MainActivity.this, items[index], Toast.LENGTH_SHORT).show();
}
});
alertBuilder.setPositiveButton("确定", new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface arg0, int arg1) {
//TODO 业务逻辑代码

// 关闭提示框
alertDialog2.dismiss();
}
});
alertBuilder.setNegativeButton("取消", new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface arg0, int arg1) {
// TODO 业务逻辑代码

// 关闭提示框
alertDialog2.dismiss();
}
});
alertDialog2 = alertBuilder.create();
alertDialog2.show();
}

// 多选提示框
private AlertDialog alertDialog3;
public void showMutilAlertDialog(View view){
final String[] items = {"Struts2","Spring","Hibernate","Mybatis","Spring MVC"};

// 创建一个AlertDialog建造者
AlertDialog.Builder alertDialogBuilder= new AlertDialog.Builder(this);
// 设置标题
alertDialogBuilder.setTitle("java EE 常用框架");
// 参数介绍
// 第一个参数：弹出框的信息集合，一般为字符串集合
// 第二个参数：被默认选中的，一个布尔类型的数组
// 第三个参数：勾选事件监听
alertDialogBuilder.setMultiChoiceItems(items, null, new DialogInterface.OnMultiChoiceClickListener() {
@Override
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
// dialog：不常使用，弹出框接口
// which：勾选或取消的是第几个
// isChecked：是否勾选
if (isChecked) {
// 选中
Toast.makeText(MainActivity.this, "选中"+items[which], Toast.LENGTH_SHORT).show();
}else {
// 取消选中
Toast.makeText(MainActivity.this, "取消选中"+items[which], Toast.LENGTH_SHORT).show();
}

}
});
alertDialogBuilder.setPositiveButton("确定", new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface arg0, int arg1) {
//TODO 业务逻辑代码

// 关闭提示框
alertDialog3.dismiss();
}
});
alertDialogBuilder.setNegativeButton("取消", new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface arg0, int arg1) {
// TODO 业务逻辑代码

// 关闭提示框
alertDialog3.dismiss();
}
});
alertDialog3 = alertDialogBuilder.create();
alertDialog3.show();
}

}
