1.安卓打包
cd android && ./gradlew assembleRelease
2.导航返回上一页
this.props.navigator.pop()
3.界面反向传值
第一个界面
this.props.navigator.push({
screen: 'N_Calendars',
title:'选择日期',
backButtonTitle: '', // 返回按钮的文字 (可选)
backButtonHidden: false, // 是否隐藏返回按钮 (可选)
passProps: {
identifying:'day',
callback:this.choosedTime.bind(this)
}
});
第二个界面
this.props.callback('要传的值');
4.tabbar 设置角标
this.props.navigator.setTabBadge({
badge:this.state.messageNum // 数字气泡提示, 设置为null会删除
});
5.页面将要加载的时候
constructor(props){
super(props)
this.state = {
};
this.props.navigator.setOnNavigatorEvent(this.onNavigatorEvent.bind(this));
}
onNavigatorEvent(event) { // this is the onPress handler for the two buttons together
// console.log('ApplicationCenterPage event.type', event.type);
if(event.id==='willAppear'){
// this.getMessageList();
}
}
6.通知 DeviceEventEmitter
DeviceEventEmitter.emit('loginSuccess');
// 接收
componentDidMount() {
this.loginSuccess = DeviceEventEmitter.addListener('loginSuccess', () => {
this._getBookList();
})
}
// 接收界面销毁
componentWillUnmount() {
this.loginSuccess.remove()
}
7.提示框
import Alert from "react-native-alert";
Alert.alert('确定退出', '',
[
{text: '取消', onPress: () => console.log('Cancel Pressed'), style: 'cancel'},
{
text: '确定',
color:'#729DD5',
onPress: () => {
UserInfoStore.removeUserToken(null);
UserInfoStore.removeUserInfo(null);
loginJumpSingleton.goToLogin(this.props.navigator);
},
},]
, {cancelable: false}
);
Alert.alert('确定退出', '',
[{text: '确定', onPress: () => console.log('Cancel Pressed')},]
, {cancelable: false}
);
8.react-native清除android项目缓存的命令
cd到android目录下执行
./gradlew clean
(./gradlew --stop 停止)
9.react-native 连接android Debug包的命令
adb reverse tcp:8081 tcp:8081
