react native picker is not showing in android

Issue

I am trying to add picker in react native android but it does not showing in android. I map my location date to picker item but i did'nt see picker in screen.

<Picker selectedValue={this.state.location}>
  <Picker.Item label="Location 1" value="1" /> 
  <Picker.Item label="Location 2" value="2" />
  <Picker.Item label="Location 3" value="3" />
</Picker>

Solution

You need to set your onValueChange method

<Picker
    style={{width: 100}} 
    selectedValue={this.state.location}
    onValueChange={(loc) => this.setState({location: loc})}>
  <Picker.Item label="Location 1" value="1" /> 
  <Picker.Item label="Location 2" value="2" />
  <Picker.Item label="Location 3" value="3" />
</Picker>
