joaodias commented 9 years ago

Hi, I'm using the rangeBar with a single value. I have a bar with 24 indexes and whenever the pin crosses the index 3 the application throws a NullPointerException. Anyone having the same problem? I already try to play with some xml properties but I still have the problem.

Below is my xml code:

<com.appyvet.rangebar.RangeBar
                xmlns:custom="http://schemas.android.com/apk/res-auto"
                android:id="@+id/slider"
                android:layout_width="wrap_content"
                android:layout_height="64dp"
                custom:tickStart="0"
                custom:tickInterval="1"
                custom:tickEnd="24"
                custom:pinColor="#ec3852"
                custom:pinRadius="10dp"
                custom:selectorColor="#ec3852"
                custom:tickColor="#00ffffff"
                custom:selectorSize="4dp"
                custom:connectingLineColor="#ec3852"
                custom:connectingLineWeight="1dp"
                custom:pinMaxFont="10sp"
                custom:barWeight="1dp"
                custom:rangeBar="false"
                android:layout_alignTop="@+id/search_radius"
                android:layout_alignEnd="@+id/slider2"
                android:layout_toEndOf="@+id/auto"
                android:layout_alignStart="@+id/slider2"
                android:layout_marginTop="8dp" />
