参照官方例子练习组件的使用,练习View Image Text 还有Android平台的DrawerLayoutAndroid
效果图:
React-Native 中的 width,height的 100%
在React-Native 中没有百分比这样的宽高,但是有替代的,具体见 issue
flex:1 相当于 height:100%
alignSelf:'stretch' 相当于 width:100%
React-Native 的style
- 直接写在View中
<Text style={{fontFamily: 'notoserif',fontStyle: 'italic',fontWeight: 'bold'}}> NotoSerif Bold Italic </Text>
- 使用 StyleSheet.createClass 创建
var styles = StyleSheet.create({
base: {
width: 38,height: 38,},background: {
backgroundColor: '#222222',active: {
borderWidth: 2,borderColor: '#00ff00',});
- 以上两种混合
<Text style={[styles.remainder, {color: '#a1a1a1'}]}>
simple text
</Text>
Flex
DrawerLayoutAndroid侧滑菜单
DrawerLayoutAndroid 只在android中,它的 renderNavigationView 代表侧滑菜单内容,子View代表主界面布局
通过ref={(drawer) => { this.drawer = drawer; }} 获取drawer对象
打开: openDrawer()
关闭: closeDrawer()
<DrawerLayoutAndroid drawerWidth={300} drawerPosition={DrawerLayoutAndroid.positions.Left} ref={(drawer) => { this.drawer = drawer; }}
renderNavigationView={() => navigationView}>
<View></View>
</DrawerLayoutAndroid>
按钮的点击效果
根据需要的效果选择
点击函数的触发
定义函数
openDrawer: function () {
this.drawer.openDrawer();
},
设置点击事件
onPress={this.openDrawer}
