在 activity 中使用 ViewPager 并从 URL 启动应用程序膨胀抛出异常
Using ViewPager in activity and launch app from URL inflating Exception thrown
我的应用程序中有一个 android.support.v4.widget.DrawerLayout 布局，其中有一个用于滑块的 ViewPager。如果我直接打开应用程序就可以正常工作。
但是当我点击 URL 打开应用程序时，它会在 setContentView(R.layout.activity_main) 行抛出膨胀异常。
当我从代码中删除 ViewPager 时它工作正常。
任何解决方案，建议，我需要它。
或任何其他显示图像滑块的方式。我如何使用 URL 中的打开应用程序和显示滑块
