A factory has already been set on this LayoutInflater

AppCompatActivity 已经设置过了，源代码如下：

public void installViewFactory() {
LayoutInflater layoutInflater = LayoutInflater.from(mContext);
if (layoutInflater.getFactory() == null) {
LayoutInflaterCompat.setFactory(layoutInflater, this);
} else {
if (!(LayoutInflaterCompat.getFactory(layoutInflater)
instanceof AppCompatDelegateImplV9)) {
Log.i(TAG, "The Activity's LayoutInflater already has a Factory installed"
+ " so we can not install AppCompat's");
}
}
}

第二：在super.oncreate()之前设置，如下，但这种可能存在问题，可以看大神的

SkinInflateFactory skinInfateFactory=new SkinInflateFactory();
LayoutInflaterCompat.setFactory(LayoutInflater.from(this),skinInflateFactory);
super.onCreate(savedInstanceState);
