示例：
一、确定對話框
1 AlertDialog.Builder builder = new AlertDialog.Builder(this);
2 builder.setTitle("确認對話框");
3 builder.setIcon(R.drawable.icon_72);
4 builder.setMessage("這裡是對話框内容");
5 builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
6
7 @Override
8 public void onClick(DialogInterface arg0, int arg1) {
9 // TODO Auto-generated method stub
10 Toast.makeText(AlertDialog_text.this, "點選了确定按鈕", 1).show();
11 }
12 });
13 AlertDialog dialog = builder.create();
14 dialog.show(); //顯示、 View Code
二、普通清單
1 final String[] items = new String[]{"國文","數學","英語","實體","化學"}; //清單項
2 Builder alertdialog = new AlertDialog.Builder(this);
3 alertdialog.setTitle("你喜歡的課程").setItems(items, new DialogInterface.OnClickListener() {
4
5 @Override
6 public void onClick(DialogInterface dialog, int which) {
7 // TODO Auto-generated method stub
8 Toast.makeText(AlertDialog_lianxi.this, items[which], Toast.LENGTH_SHORT).show();
9
10 }
11 });
12 alertdialog.create().show(); //建立顯示清單 普通清單
三、單選清單
1 final String[] items_fruit = new String[]{"蘋果","香蕉","橘子","西瓜","梨"};
2 Builder alerdialog = new AlertDialog.Builder(this);
3 //設定清單标題
4 alerdialog.setTitle("你喜歡的水果");
5 //設定單選清單
6 alerdialog.setSingleChoiceItems(items_fruit, 0, new DialogInterface.OnClickListener() {
7 @Override
8 public void onClick(DialogInterface dialog, int which) {
9 // TODO Auto-generated method stub
10 Toast.makeText(AlertDialog_lianxi.this, items_fruit[which], Toast.LENGTH_SHORT).show();
11
12 }
13 });
14 //設定取消按鈕并且設定響應事件
15 alerdialog.setNegativeButton("取消", new DialogInterface.OnClickListener() {
16
17 @Override
18 public void onClick(DialogInterface dialog, int which) {
19 // TODO Auto-generated method stub
20 //取消按鈕響應事件
21 }
22 });
23 //添加确定按鈕 并且設定響應事件
24 alerdialog.setPositiveButton("确定", new DialogInterface.OnClickListener() {
25
26 @Override
27 public void onClick(DialogInterface dialog, int which) {
28 // TODO Auto-generated method stub
29 //确定按鈕響應事件
30 }
31 });
32
33 alerdialog.create().show();//建立顯示清單 單選清單
四、多選清單
1 final String[] items_fruit1 = new String[]{"蘋果","香蕉","橘子","西瓜","梨"}; //設定項
2 final boolean[] items_fruit_selected = new boolean[]{true,false,false,false,false};
3 Builder alerdialog1 = new AlertDialog.Builder(this);
4 //設定清單标題
5 alerdialog1.setTitle("你喜歡的水果");
6 //設定多選清單
7 alerdialog1.setMultiChoiceItems(items_fruit1, items_fruit_selected, new DialogInterface.OnMultiChoiceClickListener() {
8
9 @Override
10 public void onClick(DialogInterface dialog, int which, boolean isChecked) {
11 // TODO Auto-generated method stub
12 items_fruit_selected[which] = isChecked;
13 }
14 });
15 //設定取消按鈕并且設定響應事件
16 alerdialog1.setNegativeButton("取消", new DialogInterface.OnClickListener() {
17
18 @Override
19 public void onClick(DialogInterface dialog, int which) {
20 // TODO Auto-generated method stub
21 //取消按鈕響應事件
22 }
23 });
24 //添加确定按鈕 并且設定響應事件,将選擇的項顯示
25 alerdialog1.setPositiveButton("确定", new DialogInterface.OnClickListener() {
26
27 @Override
28 public void onClick(DialogInterface dialog, int which) {
29 // TODO Auto-generated method stub
30 //确定按鈕響應事件
31 StringBuilder stringBuilder = new StringBuilder();
32 for(int i=0;i<items_fruit_selected.length;i++)
33 {
34 if(items_fruit_selected[i] == true)
35 {
36 stringBuilder.append(items_fruit1[i]+"、");
37 }
38 }
39 Toast.makeText(AlertDialog_lianxi.this, stringBuilder.toString(), Toast.LENGTH_SHORT).show();
40 }
41 });
42
43 alerdialog1.create().show();//建立顯示清單 多選清單
5、自定義布局對話框
對話框布局檔案
1 <?xml version="1.0" encoding="utf-8"?>
2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
3 android:layout_width="match_parent"
4 android:layout_height="match_parent"
