14 //getWindow().requestFeature(Window.FEATURE_NO_TITLE);
15 setContentView(R.layout.dialog_progress);

4 new AlertDialog.Builder(this)
5 .setTitle("设置")
6 .setIcon(R.drawable.setting)
7 //which代表第几项，item点击后自动关闭，不需要Button
8 .setItems(setting, new OnClickListener() {
9 @Override
10 public void onClick(DialogInterface dialog, int which) {
11 Toast.makeText(MainActivity.this, setting[which], Toast.LENGTH_SHORT).show();
12 }
13 })

3 int choice = 0;
4 public void dialog4(View v){
5 new AlertDialog.Builder(this)
6 .setTitle("爱好单选")

8 //0代表默认选中第一个,选中不会自动关闭
9 .setSingleChoiceItems(hobby, 0, new OnClickListener() {
10 @Override
11 public void onClick(DialogInterface dialog, int which) {
12 choice = which;
13 }
14 })
15 //Button上的which永远为0，所以这里需要一个变量来保存选中的ItemID
16 .setPositiveButton("ok", new OnClickListener() {
17 @Override
18 public void onClick(DialogInterface dialog, int which) {
19 Toast.makeText(MainActivity.this, hobby[choice], Toast.LENGTH_SHORT).show();
20 }
21 })
22 .setNegativeButton("cancel",null)
23 .create().show();
24 }
单选对话框 setSingleChoiceItems
5、多选对话框AlertDialog setMultiChoiceItem

4 public void dialog5(View v){
5 new AlertDialog.Builder(this)
6 .setTitle("爱好可多选")
7 .setIcon(R.drawable.hobby)
8 //默认选中了哪些，点击也不会自动关闭
9 .setMultiChoiceItems(hobby, bool, new OnMultiChoiceClickListener() {

6、适配器对话框AlertDialog setAdapter
1 public void dialog6(View v){
2 ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, hobby);
3 new AlertDialog.Builder(this)
4 .setTitle("适配器对话框")
5 //和setItem一样，选中之后对话框就自动消失，不需要Button
6 .setAdapter(adapter, new OnClickListener() {
7 @Override
8 public void onClick(DialogInterface dialog, int which) {
