当我在7＆amp ;;中第二次触摸edittext时，我的应用程序一直崩溃10英寸设备。相同的应用程序在移动设备中运行良好。我正在为景观导向开发应用程序。 这是我的日志

我正在使用简单的edittext。适用于移动设备，不适用于平板电脑。整个应用程序处于横向方向。

Answer 1

确保您已创建以下drawable：

// for Phones
drawable-ldpi
drawable-mdpi
drawable-hdpi

//for 7 inch tablets
drawable-large-mdpi
drawable-large-hdpi(for Nexus 7)

// for 10 inch tablets
drawable-xlarge-mdpi

并在每个中加上 square_background 。
