react-navigation not working, props is undefined -


i building poc application in react-native , trying implement react-navigation

import {stacknavigator, drawernavigator} 'react-navigation';  export default class homescreen extends react.component {     constructor(props) {         super(props)         this.clicked = this.clicked.bind(this)     }      static navigationoptions = {         drawerlabel: 'home',     };      clicked = ()=> {         this.props.navigator.navigate('draweropen'); // open drawer     }      render() {         // const {navigate} = this.props.navigation;         return (             <scrollview>                 <view style={styles.container}>                      <view style={styles.header}>                         <view style={{width: 50}}>                             <touchablehighlight onpress={()=> {                                 this.clicked("draweropen")                             }}>                                 <image source={require('./img/hamburger_icon.png')}/>                             </touchablehighlight>                         </view>                     </view>                </view>            </scrollview >        )     }  }

now whenever clicking on touchable highlight, clicked function gets called , shows error:

undefined not object (evaluating '_this.props.navigator.navigate') clicked

you try :) 

 import {stacknavigator, drawernavigator} 'react-navigation';      export default class homescreen extends react.component {          static navigationoptions = {             drawerlabel: 'home',         };          clicked = () => {             this.props.navigation.navigate('draweropen'); // open drawer         }          render() {             // const {navigate} = this.props.navigation;             return (                 <scrollview>                     <view style={styles.container}>                          <view style={styles.header}>                             <view style={{width: 50}}>                                 <touchablehighlight onpress={()=>                                     this.clicked()                                 }>                                     <image source={require('./img/hamburger_icon.png')}/>                                 </touchablehighlight>                             </view>                         </view>                    </view>                </scrollview >            )         }      }

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
