scroll - 文本输入占位符在 native react 中下降

Question

在我的 React Native 应用程序中，当我按下文本输入时，占位符会向下移动一点，如下图所示。我们该如何解决这个问题？只需触摸并滚动屏幕即可实现此更改。带或不带 ScrollView 都不起作用

> below is my code
           <ScrollView>
          <View style={styles.Seventh}>
            <View style={styles.Eighth}>
              <Image style={styles.Imagethird} source={require('../src/Assets/Profile-xhdpi.png')} />
            </View>
            <View style={styles.ninth}>
              <Text style={styles.Textthird}>USER'S NAME</Text>
              <TextInput placeholder="user's name               " style={styles.one} underlineColorAndroid='transparent'
            //--------------value Handler----------------//
            onChangeText={(firstName) => this.setState({firstName})}

            //---------------------------------//
              />
            </View>
            </View>
            </ScrollView>
            Seventh: {
                height: 60,
                width: '100%',
                borderRadius: 70,
                flexDirection: 'row',
                elevation: 3,
                backgroundColor: 'white',
                marginTop:10
            },
            Eighth: {
                height: 60,
                width: '20%',
                justifyContent: 'center',
                alignItems: 'center'
            },
            Imagethird: {
                height: 20,
                width: 20,
                resizeMode: 'contain',
            },
            ninth: {
                height: 60,
                width: '80%',

            },
            Textthird: {
                marginRight:29,
                marginTop: 10,
                fontSize: 12,
                color: '#C7C7CD'
            },one:{
        marginBottom:25,
        fontWeight:'bold',
     }

我认为问题出在边距上..我也遇到了这个问题，发现文本输入有默认的边距值，尝试将边距设置为0，

<TextInput style={{margin:0,padding:0}} placeholder="place holder"/>
