react native - How can I center items and selected item in RN Picker android? -

-

is possible center android picker items , selected item? i've searched everywhere, , tried alignitems:'center' & justifycontent:'center', items still aligned left (visible on photos), when put alignself:'center' picker no longer visible. have clues?

    var reports = [         {name: 'report 1', id: 'r1'},         {name: 'report 2', id: 'r2'},         {name: 'report 3', id: 'r3'},         {name: 'report 4', id: 'r4'},         {name: 'report5', id: 'r5'},         {name: 'report6', id: 'r6'}     ];      ...         <picker style={styles.androidpicker} mode={'dropdown'}                 selectedvalue={this.state.report} itemstyle={styles.reports.iospicker}                 onvaluechange={(reportid) => this.onreportchanged(reportid)}>            {reports.map(function (reports) {                 return <picker.item style={{alignself:'center'}} label={reports.name}                             value={reports.id} key={reports.name + reports.id}/>;})} </picker>      ...

styles: 

var styles = stylesheet.create({     androidpicker: {             flex: 1,             color: '#6d6d6d',             backgroundcolor: '#fff',             marginbottom: 20,             height: 40,              alignitems:'center',              justifycontent:'center',             flexdirection: 'row'         } })
