Mig*_*rti 6 keyboard jsx react-native
我正在使用 React Native 开发一个应用程序,我们有设计师制作的屏幕布局。但我无法正确实现预期的行为。基本上它是一个带有一些文本输入和一个按钮的屏幕,我需要在键盘出现时正确调整的东西。以下是预期的屏幕:
\n\n因此,当键盘出现时,按钮必须向上移动很多,两个文本输入都会向上移动一点,并且顶部的文本保持不变。没有键盘时屏幕看起来很完美,但现在键盘出现时它什么也不做。我尝试了很多东西,但没有任何效果。现在是渲染方法:
\nrender() {\n const textInputBorderColor = this.state.hasError ? Colors.error : Colors.background;\n const textInputCpfMarginTop = this.state.hasError ? 24 : 48;\n\n return (\n <View style = {styles.container}>\n <KeyboardAvoidingView behavior=\'padding\'>\n <Text style = {styles.headerText}>Vamos come\xc3\xa7ar!</Text>\n \n <TextInput \n value = {this.props.user.name} \n onChangeText = {text => this.props.user.name = text}\n placeholder = \'Insira aqui seu nome completo\'\n style = {[styles.textInputName, {borderColor: textInputBorderColor}]}\n />\n\n <ErrorText show = {this.state.hasError} value = {this.state.errorMsg}/>\n\n <TextInputMask\n value = {this.props.user.cpf}\n onChangeText = {text => this.props.user.cpf = text}\n placeholder = \'e aqui seu CPF\'\n keyboardType = \'numeric\'\n type = \'cpf\'\n style = {[styles.textInputCpf, {borderColor: Colors.background, marginTop: textInputCpfMarginTop}]}\n />\n \n <View style = {{marginTop: 202}}>\n <DefaultButton \n onPress = {this.onButtonPress}\n btnLabel = \'Continuar\'\n disabled = {(this.props.user.name == \'\' || this.props.user.cpf.length != 14)}\n />\n </View>\n </KeyboardAvoidingView>\n </View>\n );\n}\nRun Code Online (Sandbox Code Playgroud)\n款式:
\nconst styles = StyleSheet.create({\n container: {\n flex: 1,\n backgroundColor: \'#FFFFFF\',\n alignItems: \'center\',\n },\n\n textInputName: {\n textAlign: \'center\',\n fontFamily: \'Roboto-Light\',\n fontSize: 16,\n paddingBottom: ScreenDimensions.width * 0.01,\n borderBottomWidth: 1,\n marginTop: 96,\n width: 321\n },\n\n textInputCpf: {\n textAlign: \'center\',\n fontFamily: \'Roboto-Light\',\n fontSize: 16,\n paddingBottom: ScreenDimensions.width * 0.01,\n borderBottomWidth: 1,\n width: 321\n },\n \n headerText: {\n marginTop: 66,\n textAlign: \'center\',\n fontFamily: \'Roboto-Light\',\n fontSize: 20,\n color: \'#000\'\n }\n})\nRun Code Online (Sandbox Code Playgroud)\n该组件(keyboardAvoidingView)的文档毫无价值......
\n非常感谢您的帮助!
\n忘记发布对我们有用的内容。经过一些测试,我们找到了可行的解决方案。我们将文本输入包围在 a 中ScrollView,以便在使用小屏幕设备时它可以正常工作,并且只用 包围按钮KeyboardAvoidingView。两者都被外层包围View。
这是一个例子:
<View style = {{flex: 1, alignItems: 'center', justifyContent: 'flex-end'}}>
<ScrollView
contentContainerStyle={{ flexGrow: 1, justifyContent: 'center' }}
style={{ alignSelf: 'stretch' }}
>
# Your Text Inputs
</ScrollView>
<KeyboardAvoidingView
behavior='padding'
keyboardVerticalOffset={Platform.OS == 'ios' ? Header.HEIGHT + getStatusBarHeight() : Header.HEIGHT + 32}
style={{ flex: 1, justifyContent: 'flex-end', alignSelf: 'stretch', marginBottom: 16 }}
>
# Yout Button
</KeyboardAvoidingView>
</View>

旁注:在 ScrollViews 中使用文本输入和按钮时要小心(这不是我的解决方案的情况),因为有一个小问题,您无法在键盘打开的情况下单击按钮。
