本文介绍了在Android应用中实现不同类型的对话框方法，包括带进度条的ProgressDialog、单选框、多选框及列表框等，并提供了详细的代码示例。

由于都是比较常见的,且容易懂,代码量较少:
1,带进度条的对话框ProgressDialog:可以想象一下应用场景,当我们登录扣扣账号后,点击“确定”，将跳转到登录等待界面
这里写图片描述

其代码实现为:
ProgressDialog dialog = new ProgressDialog();
dialog.show();

2,单选框的实现

private Dialog mDialog;
AlertDialog build = new AlertDialog.Builder(this)
    build.setTitle("请选择");
    build.setIcon(android.R.drawable.ic_dialog_info)                
    build.setSingleChoiceItems(new String[] {"红色","紫色","绿色","蓝色"}, 0, 
      new DialogInterface.OnClickListener() {

         public void onClick(DialogInterface dialog, int which) {
            mDialog.dismiss();
         }
      });
    build.setNegativeButton("取消", null)
    mDialog = build.show();

3,多选框的实现

private Dialog mDialog;
AlertDialog build = new AlertDialog.Builder(this)
    build.setTitle("请选择");
    build.setIcon(android.R.drawable.ic_dialog_info)                
    build.setMultiChoiceItems(new String[] {"红色","蓝色","紫色","黑色"}, null, null)
    build.setPositiveButton("确认", null)
    build.setNegativeButton("取消", null)
    mDialog = build.show();

4,列表框的实现

private Dialog mDialog;
AlertDialog build = new AlertDialog.Builder(this)
    build.setTitle("请选择");
    build.setIcon(android.R.drawable.ic_dialog_info)                
    build.setItems(new String[] {"红色","蓝色","紫色","黑色"}, null)
    build.setPositiveButton("确认", null)
    build.setNegativeButton("取消", null)
    mDialog = build.show();
