项目介绍
该组件进行封装一个时间日期选择器,同时适配Android、iOS双平台，该组件基于@remobile/react-native-datetime-picker进行开发而来
配置安装
npm install react-native-datetime --save
1.1.iOS环境配置
上面步骤完成之后，直接前台写js代码即可
1.2.Android环境配置
在android/setting.gradle文件中如下配置
...
include ':react-native-datetime'
project(':react-native-datetime').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-datetime/android')
在android/app/build.gradle文件中如下配置
...
dependencies {
...
compile project(':react-native-datetime')
}
在MainActivity.java中进行注册模块
①.React Native>=0.18开始
import com.keyee.datetime.*; // <--- import
public class MainActivity extends ReactActivity {
......
/**
* A list of packages used by the app. If the app uses additional views
* or modules besides the default ones, add more packages here.
*/
@Override
protected List<ReactPackage> getPackages() {
return Arrays.<ReactPackage>asList(
new RCTDateTimePickerPackage(this), // <------ add here
new MainReactPackage());
}
}
①.React Native<=0.17版本
import com.keyee.datetime.*; // <--- import
public class MainActivity extends Activity implements DefaultHardwareBackBtnHandler {
......
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mReactRootView = new ReactRootView(this);
mReactInstanceManager = ReactInstanceManager.builder()
.setApplication(getApplication())
.setBundleAssetName("index.android.bundle")
.setJSMainModuleName("index.android")
.addPackage(new MainReactPackage())
.addPackage(new RCTDateTimePickerPackage(this)) // <------ add here
.setUseDeveloperSupport(BuildConfig.DEBUG)
.setInitialLifecycleState(LifecycleState.RESUMED)
.build();
mReactRootView.startReactApplication(mReactInstanceManager, "ExampleRN", null);
setContentView(mReactRootView);
}
......
}

使用方法
<DateTimePicker ref={(picker)=>{this.picker=picker}}/>
...
this.picker.showDatePicker(...)
this.picker.showTimePicker(...)
this.picker.showDateTimePicker(...)
在ios平台上面使用，需要确保当前DataTimePicker视图在顶部
使用实例
'use strict';
var React = require('react-native');
var {
StyleSheet,
TouchableOpacity,
View,
Text,
} = React;
var DateTimePicker = require('react-native-datetime');
var Button = require('@remobile/react-native-simple-button');
module.exports = React.createClass({
getInitialState() {
return {
date: new Date(),
}
},
showDatePicker() {
var date = this.state.date;
this.picker.showDatePicker(date, (d)=>{
this.setState({date:d});
});
},
showTimePicker() {
var date = this.state.date;
this.picker.showTimePicker(date, (d)=>{
this.setState({date:d});
});
},
showDateTimePicker() {
var date = this.state.date;
this.picker.showDateTimePicker(date, (d)=>{
this.setState({date:d});
});
},
render() {
return (
<View style={styles.container}>
<Text style={{textAlign: 'center'}}>
{this.state.date.toString()}
</Text>
<View style={{height:40}} />
<Button onPress={this.showDatePicker}>showDatePicker</Button>
<View style={{height:40}} />
<Button onPress={this.showTimePicker}>showTimePicker</Button>
<View style={{height:40}} />
<Button onPress={this.showDateTimePicker}>showDateTimePicker</Button>
<DateTimePicker ref={(picker)=>{this.picker=picker}}/>
</View>
);
},
});
var styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
paddingTop:20,
},
});
