app:srcCompat与ImageView允许向后兼容使用载体可绘的.但是,你怎么能与其他使用它们View小号之外ImageView？例如,TextView属性就像android:drawableLeft.

同时使用矢量drawable作为android:iconwith MenuItem导致崩溃,但有以下异常:

Fatal Exception: android.view.InflateException: Binary XML file line #2: Error inflating class <unknown>

使用支持库23.2.0,如何解决此问题？

我对使用app:srcCompat="@drawable/icon"support-library 23.2.0中引入的属性将矢量drawables设置为布局的新可能性感到非常兴奋.

但我想知道如何以编程方式获取其中一个drawables或者设置为背景.

我想到了类似的东西: ContextCompat.getDrawable(context, R.drawable.icon)

这甚至可能吗？
