[英]React Native get TextInput value and use on the same View using onBlur or onFocus method
I would like to get the value from a TextInput picker (using react-native-material-dropdown) and perform calculations on close of dropdown using the blur method, the dropdown is numeric. 我想从TextInput选择器中获取值(使用react-native-material-dropdown),并使用blur方法在下拉列表关闭时执行计算,下拉列表是数字。
<Dropdown
label='meals'
data={data}
onChangeText={this.onRegularMealChange.bind(this)}
value={this.props.regularMeal}
/>
would like to do something like: 想做类似的事情:
<View>
<Text>{amount * this.props.regularMeal}</Text>
</View>
</View>
我的减速器有问题。
