4月23日进度
昨天太晚忘记发了，昨天我按照分配的任务完成了关于设置方面的页面设计及跳转，之后我们发现，代码的健壮性存在很多问题，首先是修改密码等输入框中不能为空的问题，要判断不能为空需要调用的UtilsText.isEmpty方法时发生错误，可能是我没有导包的缘故，由于时间紧迫将由另一个已经设置好工具类的成员去完成这部分功能，其次现在遇到的问题还有点击退出登录返回到登录界面后，按返回不是退出程序而是返回到设置界面，这两个问题我们将在今天或明天完成初步的合并之后去解决，今天（24日）的目标是完成主页面的设计，如果时间富裕团队将尝试将所有的代码进行整合，由于版本不同等原因可能会遇到很多问题，希望一切顺利。下面是我昨天（23日）完成的代码：
（由于登录界面由其他成员完成，我简单的弄了一个游客登录按钮，点击后直接跳转到设置界面）：
Main：

}
startActivity(intent);

}
private long mExitTime;
/**

*/
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
if ((System.currentTimeMillis() - mExitTime) > 2000) {
Object mHelperUtils;
Toast.makeText(this, "再按一次退出APP", Toast.LENGTH_SHORT).show();
//System.currentTimeMillis()系统当前时间
mExitTime = System.currentTimeMillis();
} else {
finish();
}
return true;
}
return super.onKeyDown(keyCode, event);
}
}
