配合navigation设置StatusBar

componentDidMount() {
  this._navListener = this.props.navigation.addListener("didFocus", () => {
    StatusBar.setBarStyle("light-content");
    isAndroid && StatusBar.setBackgroundColor('#6a51ae');
    // StatusBar.setBarStyle('dark-content');
    // isAndroid && StatusBar.setBackgroundColor('#ecf0f1');
  });
}
componentWillUnmount() {
  this._navListener.remove();
}
