title: SetState called many times
body: <p>I have a problem concerning the display of My DateTimePicker Widget !! I have written the code below and this error is occured <strong>Maximum update depth exceeded This can happen when a  component repeatedly calls setState</strong> I dont see any infinte code in my own . I defined <code>SetState</code> in 2 parts of my code, when i run it ,It displays a big calendar which is set to a date which is not the initial one in my <code>state</code> above !! few seconds later it dsplays the error ..! 
  I have defined within my code , 3 other <code>view</code> which are not mentionned during the display onmy the big <code>calendar</code> is displayed !!</p>
  
  <pre><code>constructor(props){
       super(props);
       this.state={
       selectedLabel:'4 mois',
       value : parseInt('2020-06-20')
                  }
  
  Show (value){
          this.setState({selectedLabel :value});
      }
  
  render () {
  
                         &lt;Picker style={{marginLeft:10,width:260}} 
                               selectedValue={this.state.selectedLabel} onValueChange={this.Show()}&gt;
                              &lt;Picker.Item label= "1 semaine"&gt;&lt;/Picker.Item&gt;
                              &lt;Picker.Item label=" 15 jours "&gt;&lt;/Picker.Item&gt;
