react-native - React-native-multiple-select 在提交时获取项目

Question

我正在使用react-native-multiple-select它的工作，但是，我想做的是在我提交之后而不是在我选择时获取所有选定的项目。

<MultiSelect
      hideTags
      items={this.filter_pref}
      uniqueKey="id"
      ref={(component) => { this.multiSelect = component }}
      onSelectedItemsChange={this.onSelectedItemsChange}
      selectedItems={selectedItems}
      selectText="Zgjedh "
      searchInputPlaceholderText="Kerko filterat..."
      // onChangeInput={(text) => console.log(text)}
      altFontFamily="ProximaNova-Light"
      tagRemoveIconColor="#CCC"
      tagBorderColor="#CCC"
      tagTextColor="#CCC"
      selectedItemTextColor="#CCC"
      selectedItemIconColor="#CCC"
      itemTextColor="#000"
      displayKey="name"
      searchInputStyle={{ color: '#CCC' }}
      submitButtonColor="#CCC"
      submitButtonText="Zgjedh"
      />

以及我设置值的函数：

 onSelectedItemsChange = selectedItems => {

        this.setState({ selectedItems });
}
