自定义react navigation跳转动画,实现上下左右跳转页面。
const StackOptions = ({navigation}) => {
const gesturesEnabled = true;
const headerStyle= {
height:Platform.OS==='ios'?SCALE(100):SCALE(60),
backgroundColor: Color.e35041,
borderWidth:0,
};
const headerTitleStyle = {
fontSize: FONT(17),
color: 'white',
alignSelf: 'center'
};
const headerTintColor= 'white';
const headerLeft = (
<TouchableOpacity activeOpacity={1} onPress={()=>{navigation.goBack(null)}}>
<View style={{paddingLeft:SCALE(30)}}>
<Icon name={'md-arrow-back'} size={25} color={'white'}/>
</View>
</TouchableOpacity>
);
const headerRight=(<View style={{paddingRight:SCALE(10)}}>
<Icon name="md-home" size={25} color={'transparent'}/>
</View>);
return {headerLeft,headerRight,headerStyle,gesturesEnabled,headerTitleStyle,headerTintColor,}
};
/*
* 从上至下动画
* */
const forVerticalTop = (sceneProps)=>{
const { layout, position, scene } = sceneProps;
const index = scene.index;
const height = layout.initHeight;
const width = layout.initWidth;
console.log('index',index);
console.log('position',position);
const opacity = position.interpolate({
inputRange: ([
index - 1,
index - 0.99,
index,
index + 0.99,
index + 1,
]: Array<number>),
outputRange: ([1, 1, 1, 0.85, 0]: Array<number>),
});
const translateX = 0;
// const translateX = position.interpolate({
// inputRange: ([index, index+1, index + 1]: Array<number>),
// outputRange: ([0,width,0]: Array<number>),
// });
const translateY = position.interpolate({
inputRange: ([index, index+1, index + 1]: Array<number>),
outputRange: ([0,height,height,]: Array<number>),
});
return {
opacity,
transform: [{ translateX }, { translateY }],
};
};
/*
* 从左至右动画
* */
const forHorizontalLeft = (sceneProps)=>{
const { layout, position, scene } = sceneProps;
const index = scene.index;
const inputRange = [index - 1, index, index + 1];
const width = layout.initWidth;
const outputRange = I18nManager.isRTL
? ([width, 0, -width * 0.3]: Array<number>)
: ([-width, 0, width * -0.3]: Array<number>);
// Add [index - 1, index - 0.99] to the interpolated opacity for screen transition.
// This makes the screen's shadow to disappear smoothly.
const opacity = position.interpolate({
inputRange: ([
index - 1,
index - 0.99,
index,
index + 0.99,
index + 1,
]: Array<number>),
outputRange: ([0, 1, 1, 0.85, 0]: Array<number>),
});
const translateY = 0;
const translateX = position.interpolate({
inputRange,
outputRange,
});
return {
opacity,
transform: [{ translateX }, { translateY }],
};
};
//实现定义某个页面的动画效果
const TransitionConfiguration = () => {
return {
transitionSpec: {
duration: 300,
easing: Easing.linear(),
timing: Animated.timing,
},
screenInterpolator: (sceneProps) => {
const {scene } = sceneProps;
const { route,index } = scene;
const params = route.params || {};
const transition = params.transition || 'forHorizontal';
switch (transition){
case 'forVerticalTop':
return forVerticalTop(sceneProps);
case 'forHorizontalLeft':
return forHorizontalLeft(sceneProps);
default:
return CardStackStyleInterpolator[transition](sceneProps);
}
},
};
};
const AppNavigator = StackNavigator(
{
...Routes,
Index: {
screen: Launch,
},
},
{
initialRouteName: 'Index',
headerMode: 'screen',
transitionConfig: TransitionConfiguration,
navigationOptions: ({navigation}) => StackOptions({navigation}),
}
);
export default () => <AppNavigator />;
使用方法:
this.props.navigation.navigate('Vacation', {transition: 'forVertical'});
