android编程实现对话框的封装实例

本文实例讲述了android编程实现对话框的封装。分享给大家供大家参考，具体如下：

/**
* 对话框
*/
private static progressdialog mprogressdialog;
/**
* 默认的对话框
* 标题、内容、两个按钮
* @param context
* @param title
* @param content
* @param btnokstr 是空字符的话 该按钮不显示 (特别注意)
* @param btncancelstr 是空字符的话 该按钮不显示
* @param onclick
*/
public static void showdefaultdialog(context context,string title,string content,
   string btnokstr,string btncancelstr,onclicklistener onclick){
  showdefaultdialog(context, title, content, btnokstr, btncancelstr, onclick, null);
}
/**
* 默认的对话框 + cancel事件
* @param context
* @param title
* @param content
* @param btnokstr
* @param btncancelstr
* @param onclick
* @param oncancel
*/
public static void showdefaultdialog(context context,string title,string content,
   string btnokstr,string btncancelstr,
   onclicklistener onclick,oncancellistener oncancel){
  alertdialog.builder mbuilder = new alertdialog.builder(context);
  if(title != null){
   mbuilder.settitle(title);
  }
  mbuilder.setmessage(content);
  if(btnokstr == null)
   btnokstr = "确定";
  if(btncancelstr == null)
   btncancelstr = "取消";
  if(!btnokstr.trim().equals(""))
   mbuilder.setpositivebutton(btnokstr, onclick);
  if(!btncancelstr.trim().equals(""))
   mbuilder.setnegativebutton(btncancelstr, onclick);
  if(oncancel != null){
   mbuilder.setoncancellistener(oncancel);
  }
  mbuilder.show();
}
public static void showprogressdialog(context context,string msg,boolean cancelable) {
//  dismissprogressdialog();
  mprogressdialog = new progressdialog(context);
  mprogressdialog.setmessage(msg);
  mprogressdialog.setcancelable(cancelable);
  mprogressdialog.show();
}
public static void dismissprogressdialog(){
  if (mprogressdialog != null && mprogressdialog.isshowing()) {
   mprogressdialog.dismiss();
   mprogressdialog = null;
  }
}

希望本文所述对大家android程序设计有所帮助。
