We recommend using the AndroidX libraries in all new projects. You should also consider[migrating](https://developer.android.com/jetpack/androidx/migrate)existing projects to AndroidX.

*** ** * ** *** Picker column class used by[Picker](https://developer.android.com/reference/android/support/v17/leanback/widget/picker/Picker), defines a contiguous value ranges and associated labels. A PickerColumn has a minValue and maxValue to choose between. The Picker column has a current value. The labels can be dynamically generated from value by[setLabelFormat(String)](https://developer.android.com/reference/android/support/v17/leanback/widget/picker/PickerColumn#setLabelFormat(java.lang.String))or a list of static labels set by[setStaticLabels(CharSequence[])](https://developer.android.com/reference/android/support/v17/leanback/widget/picker/PickerColumn#setStaticLabels(java.lang.CharSequence[])). ## Summary | ### Public constructors || |----------------------------------------------------------------------------------------------------------------------------------------|---| | ` `[PickerColumn](https://developer.android.com/reference/android/support/v17/leanback/widget/picker/PickerColumn#PickerColumn())`() ` | | ### Public methods || |-------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | ` int` | ` `[getCount](https://developer.android.com/reference/android/support/v17/leanback/widget/picker/PickerColumn#getCount())`() ` Get total items count between minValue and maxValue. | | ` int` | ` `[getCurrentValue](https://developer.android.com/reference/android/support/v17/leanback/widget/picker/PickerColumn#getCurrentValue())`() ` Returns current value of the Column. | | ` CharSequence` | ` `[getLabelFor](https://developer.android.com/reference/android/support/v17/leanback/widget/picker/PickerColumn#getLabelFor(int))`(int value) ` Get a label for value. | | ` String` | ` `[getLabelFormat](https://developer.android.com/reference/android/support/v17/leanback/widget/picker/PickerColumn#getLabelFormat())`() ` Return string format (see[format(String, Object...)](https://developer.android.com/reference/java/lang/String#format(java.lang.String, java.lang.Object...))) to display label for value. | | ` int` | ` `[getMaxValue](https://developer.android.com/reference/android/support/v17/leanback/widget/picker/PickerColumn#getMaxValue())`() ` Returns maximum value of the Column. | | ` int` | ` `[getMinValue](https://developer.android.com/reference/android/support/v17/leanback/widget/picker/PickerColumn#getMinValue())`() ` Returns minimal value of the Column. | | ` CharSequence[]` | ` `[getStaticLabels](https://developer.android.com/reference/android/support/v17/leanback/widget/picker/PickerColumn#getStaticLabels())`() ` Returns static labels for each value, minValue maps to labels\[0\], maxValue maps to labels\[labels.length - 1\]. | | ` void` | ` `[setCurrentValue](https://developer.android.com/reference/android/support/v17/leanback/widget/picker/PickerColumn#setCurrentValue(int))`(int value) ` Sets current value of the Column. | | ` void` | ` `[setLabelFormat](https://developer.android.com/reference/android/support/v17/leanback/widget/picker/PickerColumn#setLabelFormat(java.lang.String))`(String labelFormat) ` Set string format (see[format(String, Object...)](https://developer.android.com/reference/java/lang/String#format(java.lang.String, java.lang.Object...))) to display label for an integer value. | | ` void` | ` `[setMaxValue](https://developer.android.com/reference/android/support/v17/leanback/widget/picker/PickerColumn#setMaxValue(int))`(int maxValue) ` Sets maximum value of the Column. | | ` void` | ` `[setMinValue](https://developer.android.com/reference/android/support/v17/leanback/widget/picker/PickerColumn#setMinValue(int))`(int minValue) ` Sets minimal value of the Column. | | ` void` | ` `[setStaticLabels](https://developer.android.com/reference/android/support/v17/leanback/widget/picker/PickerColumn#setStaticLabels(java.lang.CharSequence[]))`(CharSequence[] labels) ` Set static labels for each value, minValue maps to labels\[0\], maxValue maps to labels\[labels.length - 1\]. | | ### Inherited methods | |-----------------------|---| | [![](https://developer.android.com/static/assets/images/styles/disclosure_down.png)](https://developer.android.com/reference/android/support/v17/leanback/widget/picker/PickerColumn#)From class` java.lang.Object ` |-------------------|-------------------------------| | ` Object` | ` clone() ` | | ` boolean` | ` equals(Object arg0) ` | | ` void` | ` finalize() ` | | ` final Class` | ` getClass() ` | | ` int` | ` hashCode() ` | | ` final void` | ` notify() ` | | ` final void` | ` notifyAll() ` | | ` String` | ` toString() ` | | ` final void` | ` wait(long arg0, int arg1) ` | | ` final void` | ` wait(long arg0) ` | | ` final void` | ` wait() ` | || ## Public constructors ### PickerColumn added in[version 24.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` PickerColumn () ```
