我的布局XML中有 android.support.v7.widget.AppCompatButton 。我的应用程序在Android SDK 21上正常运行，但不幸的是，它在Android SDK 16中停止了（我在AndroidManifest.xml中的minSDKVersion是16）。 我的 AppCompatButton 是这样的：
<android.support.v7.widget.AppCompatButton
android:id="@+id/button_next"
android:layout_width="45dp"
android:layout_height="25dp"
android:layout_gravity="center_vertical|start"
android:drawableBottom="@drawable/ic_navigate_next" />
并且错误是这样的：

为什么会出现此问题以及如何解决此问题？
答案 0 :(得分：0)
您可能已根据版本/ screen_size将可绘制文件夹分开 确保您的drawable存在于所有版本中，或者如果您没有，只需将它的副本放在您的基础“drawable”文件夹中
android:drawableBottom="@drawable/ic_navigate_next"
ic_navigate_next 必须位于所有可绘制文件夹中或主要可绘制
中的一个普通文件夹中看看它有用吗？
答案 1 :(得分：0)
如果你的drawable是一个可绘制的矢量，那么可能就是它。 看到： 这是[链接]（Is it possible to use VectorDrawable in Buttons and TextViews using android:DrawableRight?）！
