android - TypedArray.getDimensionPixelSize crash -


when use 

typedarray = context.obtainstyledattributes(attrs, com.android.internal.r.styleable.view, defstyle, 0); a.getdimensionpixelsize(com.android.internal.r.styleable.view_padding, layout_unknow);

the typedarray.getdimensionpixelsize(typedarray.java:572) method crashed in android 5.0

the log follows:

caused by: java.lang.unsupportedoperationexception: can't convert dimension: type=0x3 e androidruntime:   @ android.content.res.typedarray.getdimensionpixelsize(typedarray.java:572)

how can solve issue?
