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。
