那里弹出，那里调用即可：

//创建dialogCustomDialog.Builder builder = new CustomDialog.Builder(getContext());builder.setMessage(getResources().getString(R.string.service_number_tips));builder.setTitle("");builder.setPositiveButton("我知道了", new DialogInterface.OnClickListener() {    public void onClick(DialogInterface dialog, int which) {        dialog.dismiss();        //设置操作事项            }});builder.create().show();
