描述
Description
I've two input fields in my application.
<ScrollView>
<View>
<TextInput
placeholder="Enter amount:"
value={firstInput}
showSoftInputOnFocus={false}
onFocus={()=>setShowCalculator(true)}
onBlur={()=>setShowCalculator(false)}
/>
<TextInput
placeholder="Enter description:"
value={secondInput}
/>
</View>
</ScrollView>
When we click the first input is clicked, the keyboard is not shown instead calculator is shown. And when we click the second input, it opens the default keyboard. It works completely fine when I click one input, unfocus it by clicking outside the input and then click another input. But the issue arises when I click the second input and without unfocusing it, I click on the first input.
Issue:
When the second TextInput is focused, the keyboard is displayed. Then when I press the first input (when the second input is focused and the keyboard is open), it focuses the first input but the keyboard is not dismissed.
To solve this, i added onBlur={()=>Keyboard.dismiss()} to the second input. After adding this prop, when I switch the cursor from the second TextInput to the first, the keyboard is hidden this time, but the first TextInput is not focused. I must press the first TextInput again to make it focused.
Question:
When the second input field is focused and the keyboard is open, how to make the first TextInput get focus immediately when I press it and show the calculator, not the keyboard?

Steps to reproduce
- Create two input fields within a view wrapped inside a scroll view.
- Add showSoftInputOnFocus={false} to the first input only.
- Run the application.
- Click on the first input. It doesn't open the keyboard.
- Click on the second input. It will make it focused and opens the keyboard.
- Now when you are on the second input and the keyboard is open, click on the first input. It doesn't dismiss the keyboard. The keyboard still exists for the first input having showSoftInputOnFocus props as false.
- Now, to solve this, add onBlur={Keyboard.dismiss} on second input.
- Now when you are on the second input and the keyboard is open, click on the first input. It hides the keyboard but the first input field is not focused, instead, you've to tap the first input again to get focused.

import React, {useState} from 'react';
import { Text, View, TextInput, ScrollView, SafeAreaView } from 'react-native';
export default function App() {
const [showCalculator, setShowCalculator] = useState(false);
return (
<ScrollView style={{flex:1 , marginTop: 60}}>
<View>
<TextInput
placeholder="Enter amount:"
showSoftInputOnFocus={false}
onFocus={()=>setShowCalculator(true)}
onBlur={()=>setShowCalculator(false)}
/>
<TextInput
placeholder="Enter description:"
/>
</View>
</ScrollView>
);

调研方向
首先,使用 showSoftInputOnFocus={false} 复现提供的两个 TextInput 的序列,先聚焦描述字段,然后聚焦计算器输入框。跟踪受影响平台上的 TextInput 焦点转换和软输入行为;当第一个输入框立即获得焦点、计算器显示出来且键盘被关闭时,即表示完成。
