React-native how to move screen up on textinput

You can use ScrollView to control screen up and down movements. As long as user hasn't focused any TextInput, you can disable scroll. On focus, just shift up the scrollview using Content Offset prop.

<TextInput
    onFocus={this.textInputFocused.bind(this)}
  />

textInputFocused() {
//do your stuff here. scroll screen up
}

Hope it helps!
