文本输入中的Android三星设备上的React-native键盘没有逗号

Question

I have a React-native app with TextInput and KeyboardAvoidingView . And everywhere it works well except android Samsung devices, especially Samsung A3. Because on this device the keyboard is appearing without a comma, but I need to use it on the screen.

I already tried the steps from this article , removed autoCapitalize="none" from the TextInput component, but it is not working for me.

Can somebody recommend how can I solve it please.[

 <TextInput
            style={textInput}
            placeholder={props.placeholder}
            underlineColorAndroid='transparent' editable={!props.disabled}
            keyboardType={keyboardType} 
            autoCorrect={false} selection={state.position}
            value={state.value} onChangeText={this._onChangeText}
            onFocus={this._onFocus} onBlur={this._onBlur}
            autoFocus={autoFocus}
          />

How about using

keyboardType = {'numbers-and-punctuation'} in textInput

This is yout text Input

const alphaNumericRegex =  /^[a-zA-Z0-9]*$/;

 <TextInput
          ref={ref => (this.panNumber = ref)}
          onChangeText={val => this.checkAlphaNumeric(val)}
          value={this.state.panNumber}/>



 checkAlphaNumeric = ( value) => {
    if (!alphaNumericRegex.test(value)) {
      if (this.state.panNumber.length == 1) {
        this.setState({ [panNumber]: "" });
      }
      Toast.show({
        text: "Only alphabets and digits are allowed.",
        position: "top"
      });
    } else {
      this.setState({ panNumber: value });
    }
  };

在工作期间，我发现这个错误是一个软件问题的信息，它主要存在于带有 API 5.0 的旧 Android 型号上，这是使用 Google 键盘解决此错误的最佳解决方案。
