Crash

[yaojunyi3721]

华为 P6 S-U06
Android 4.4.2,level 19
DropDownMenu:v0.9
compileSdkVersion 25
buildToolsVersion "25.0.2"
minSdkVersion 15
targetSdkVersion 25

多个menucount时会在DropDownMenu.onDraw(DropDownMenu.java:243)抛出NullPointerException

[yaojunyi3721]

已排除其他原因
确定和手机以及menucount有关

[yaojunyi3721]

就是在super.onDraw(canvas)里出的错 canvas本身并不为null
出错堆栈

我这使用场景是viewpager+3个fragment
每个Fragment都有dropdownmenu

我从这里找到了答案

试试看是否管用

解决不了 最后调高minSdkVersion到21 放弃对Android4.4及以下版本的支持
