【中文标题】Activity 在调用运行时权限时变黑【英文标题】：Activity becomes black while calling the run time permissions 【发布时间】：2016-11-28 12:25:12 【问题描述】：

我想调用运行时权限以在单击某些视图时读取联系人。所以我检查应用程序是否有权限，如果没有请求权限。但是，当请求对话框出现时，如果单击对话框上的允许或拒绝，活动将变黑并完成。当我调试应用程序时，单击允许或拒绝后它不会转到 onRequestPermissionsResult 方法。

如果权限被接受，我也会打电话给联系人 Intent。我想在与选定联系人列表相同的活动中显示这些。因此，为此我有一个列表并将联系人添加到列表 onActivitResult 方法中。

但为此，如果我从联系人中选择一些联系人，活动就会完成。它不会转到 onActivityResult 方法。

    public void showAlert(String alert,PlanEventActivity activity) 

        parent = (RelativeLayout)activity.findViewById(R.id.parentPanel);

        Snackbar snackbar = Snackbar.make(parent, alert, Snackbar.LENGTH_LONG);
        snackbar.show();

奇怪的是，相同的代码以前可以正常工作。对于旧版本。我也尝试将旧版本的相同活动复制到新版本，但仍然不起作用。

没有弄错。

有人可以帮忙吗？谢谢。。

【参考方案1】：

确保您没有在androidMenifest.xml 的活动声明中输入android:noHistory=true 属性。

【讨论】：

哦，是的.. 但我希望此活动不保留任何历史记录。 @Keval Patel 您可以在离开活动或开始新活动的任何地方呼叫finish()（使用startActivity() 或startActivityForResult()）。这将从后台堆栈中删除您的活动。【参考方案2】：

替换requestPermissions(new String[]Manifest.permission.READ_CONTACTS, PERMISSIONS_REQUEST_READ_CONTACTS);

ActivityCompat.requestPermissions(this, new String[]Manifest.permission.READ_CONTACTS, PERMISSIONS_REQUEST_READ_CONTACTS);
