以下代码在android SDK 2.2中测试过。

可选列表对话框：

	private void testItemDialog(){
		AlertDialog.Builder builder = new AlertDialog.Builder(this);
		builder.setTitle("Select a color");
		final String[] items = {"blue","red","green"};
		builder.setItems(items, new DialogInterface.OnClickListener(){
			@Override
			public void onClick(DialogInterface dialog, int which) {
				// TODO Auto-generated method stub
				Toast.makeText(getApplicationContext(), items[which], Toast.LENGTH_SHORT).show();
			}
		}).create().show();
	}

带Check box的列表对话框：

	private void testItemDialog(){
		AlertDialog.Builder builder = new AlertDialog.Builder(this);
		builder.setTitle("Select a color");
		final String[] items = {"blue","red","green"};
		builder.setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener(){
			@Override
			public void onClick(DialogInterface dialog, int which) {
				Toast.makeText(getApplicationContext(), items[which], Toast.LENGTH_SHORT).show();
			}	
		}).create().show();
	}

带进度条的对话框(圆圈状，没有百份比的那种)：

private void testProgressDialog(){
		ProgressDialog dialog = ProgressDialog.show(this, "", "Loading. Please wait...");
	}

带进度条的对话框(圆圈状，显示百份比的那种)：

Confirme对话框：

	private void confirmExit() {
		AlertDialog.Builder builder = new AlertDialog.Builder(this);
		builder.setMessage("Are you sure you want to exit")
				.setCancelable(false).setPositiveButton("Yes",
						new DialogInterface.OnClickListener() {

							@Override
							public void onClick(DialogInterface dialog,
									int which) {
								GLayout.this.finish();
							}

						}).setNegativeButton("No",
						new DialogInterface.OnClickListener() {

							@Override
							public void onClick(DialogInterface dialog,
									int which) {
								dialog.cancel();

							}

						});
		builder.setNeutralButton("Hello", null);
		Dialog alert = builder.create();
		alert.show();
	}
