Question

我正面临一个问题，即在我从图库或相机中挑选图像后尝试裁剪图像时。

当我从图库中选择图像时，它会被正确裁剪而没有任何问题。当我从相机中选择图像时，裁剪已正确完成，但它显示了一个＆＃34;中间＆＃34;屏幕如下图所示，没有直接将我带到裁剪屏幕。

注意：上图仅用于表示目的，以显示＆＃34;中间＆＃34;最近的屏幕。

我不想要这个＆＃34;中间＆＃34;最近显示的屏幕。相反，我想直接导航到裁剪意图。在像Whatsapp这样的应用程序中，当有人更改他/她的个人资料照片时，不会看到此行为。它直接导航到作物意图而不显示＆＃34;中间＆＃34;屏幕。

有人可以帮助解决这个问题吗？

这是我的完整代码

您正在启动意图。这意味着您将控制权移交给另一个应用程序。在那之后，你无法控制发生的事情。当然，每个设备上发生的情况都会有所不同，因为一些OEM会使用他们自己的Gallery应用程序或可能表现完全不同的相机应用程序。

所以不，没有办法阻止他们做那个额外的屏幕。如果您想要完全控制，请通过相机或camera2 apis自己拍照，而不是调用Intent。（注意：我实际上并没有建议这一点，但如果你想控制它是唯一的方法）。
