How to use it
First step: import the component:
import { FloatingAction } from "react-native-floating-action";
Second step: define the buttons
const actions = [ { text: "Accessibility", icon: require("./images/ic_accessibility_white.png"), name: "bt_accessibility", position: 2 }, { text: "Language", icon: require("./images/ic_language_white.png"), name: "bt_language", position: 1 }, { text: "Location", icon: require("./images/ic_room_white.png"), name: "bt_room", position: 3 }, { text: "Video", icon: require("./images/ic_videocam_white.png"), name: "bt_videocam", position: 4 } ];
Third step: use it
<View style={styles.container}> <Text style={styles.example}>Floating Action example</Text> <FloatingAction actions={actions} onPressItem={name => { console.log(`selected button: ${name}`); }} /> </View>
Open and hide it programatically
There are some cases where you want to show or hide the component without pressing the main button:
<FloatingAction ref={(ref) => { this.floatingAction = ref; }} actions={[...]} ... />
and then:
this.floatingAction.animateButton();
