成功帮人刷机，特此记录。

最近帮同事刷机，机器是HTC Desire，成功刷为HTC 官方正式版：HTC G7 Desire 2.2 ROM，ROM用的是左仔的。

下载地址：http://www.jinbo123.com/1530.html

 

首先，按住音量“-” 和 电源键，进入hboot，信息如下：

BRAVO PTV1 SHIP S-ON

HBOOT-0.83.0001

MICROP-031D

TOUCH PANEL-SYNT0101

RADIO-5.11.05.14

JUN 10 2010,12:12:05

 

当选择RECOVERY进入的时候，出现了我所不愿看到的东西，红色感叹号，没办法只好拔电池，重启进入原有系统，使用“一键无痛获取root”，同样也是参看的左仔的文章：http://www.jinbo123.com/1642.html，在这里非常感谢左仔的辛苦劳动。

 

这root的过程中，唯一有难度的是，安装android phone驱动，这个我自己第一次刷机的时候也没装好，最好换了好几台笔记本才把驱动装好，不过后来发现的问题的原因。在更新驱动的时候，选择android-usb-driver的时候，选择的目录不能到最底层目录，这里选择只能到android-usb-driver的父目录就可以了，然后更新驱动就不会出现无法安装驱动了。

安装驱动之后，手机就会自动重启，这个过程就别管了，但是一定要有耐心，不要觉得没反应，就去把电池，那样很容易出问题的。

 

获取root的过程，同时刷了recovery，这个时候再进入recovery进可以看到，刷进菜单了，同样刷机前需要wipe所有数据，这里建议wipe所有，wipe之后，就是使用flash zip from sdcard来刷机，这个时候选择之前拷贝到sdcard卡中的rom包（zip格式的），剩下的就是等待了，中间可能会提示你重启，安装提示进行就可以了。

 

刷机结束之后，开机进入系统，然后记得重启一次，就ok了。

 

刷机过程中使用的软件包，在上面两个网址中都有提供，可以直接下载，这里就不在提供了。

OnTouch 事件控制的小技巧

正常的，我们都知道android的onTouch事件常用的事件有

 

onDown, onMove, onUp,onCancel...

 

前阵子在做一个图片拖拽效果的时候，因为拖拽的后页面的处理问题。

 

导致onUp事件不能够执行，我的onUp事件响应是删除掉拖拽的图片。

 

这样每次拖拽完成后，图片都不能被remove掉，堆叠在主界面里，体验很差。

 

但是又不走onTouch事件的onUp事件，导致删除不了拖动的图片。

 

后来想到了dispatchTouchEvent,重写了该方法，因为无论onTouch事件返回true or false都要走该方法。该方法可以理解

 

为父view即最外层view的touch事件处理。

 

我要做的就是在该方法里判断onUp事件，做删除图片的操作即可。
