意图可以'；t在活动和Android 4.0之间切换

这是一个奇怪的问题，在安卓4.0+设备的情况下，我的意图无法在活动之间切换，但是，在安卓2.2/2.3设备上，它工作正常

这就是我如何定义课堂活动的意图

public static final void startActivityForResult(Activity parent, int requestCode, String userName, String photoUrl, Bitmap preview, boolean isMugshot) {
    System.out.println("photoactivity started" +requestCode+"second"+parent);
    Intent intent = new Intent(parent, PhotoActivity.class)
    .putExtra(USERNAME, userName)
    .putExtra(PHOTOURL, photoUrl)
    .putExtra(PREVIEW, preview)
    .putExtra(IS_MUGSHOT, isMugshot);
    parent.startActivityForResult(intent, requestCode);
}

我想根据特定的用户触摸响应从另一个类切换到上述活动类。我将其定义如下

case R.id.ImgAvatar:
        PhotoActivity.startActivityForResult(this, REQUEST_SHOW_AVATOR, mUserName, avatarUrl, mAvatar, true);
        break;

我的代码很好，因为在安卓2.3/2.2的情况下，我可以在活动之间切换。然而，在使用安卓4.0+设备时，我并没有在触摸响应时切换活动，而是回到了我的主要活动（不知道为什么）

我还注意到控制台输出在2.2和4.0版本中都有所不同。我仍然猜不出为什么安卓4.0会带来麻烦

这是活动正确启动时的日志（android 2.2/2.3）

这是android 4.0的日志+

显然，在安卓4.0+的情况下，我的第二个活动没有被调用，我被恢复到主活动。另一个有趣的观察结果是，实际上调用了intent，即我到达了定义intent的函数，但似乎intent无法启动活动，因此intent确实运行，但无法启动新活动。我不知道，因为我的代码没有给出任何运行/编译时错误，所以很难找到问题。谢谢你的帮助

这是我的舱单

你能为你遇到问题的活动提供AndroidManifest.xml条目吗？你现在可以看到这个链接：[link][1][1]：这可能会对你有所帮助..不，这不起作用，问题是其他的，因为在android 2.2中它工作得很好，但是在4.0+版本中，它不起作用
