Android 简单的弹出框(在屏幕中间,传string[],根据内容框框大小自适应)

private void showLabelAlert() {
  new AlertDialog.Builder(上下文)
      .setTitle("选择标签")
      .setItems(addressLabels, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
          if (which != 0) {
            文字控件.setText(addressLabels[which]);
          }
        }
      })
      .create().show();
}
String[] addressLabels = new String[]{"无", "家", "公司", "学校",};
