対応

anrdoird/app/src/mainの以下の部分を修正する

-        android:windowSoftInputMode="adjustResize">
+        android:windowSoftInputMode="adjustPan">

結果

その他

KeyboardAvoidingViewではうまくいかないときもあるみたいです。
上記の変更を行わなくても、各pageのJS側の設定でも対応できます。

react-navigationのタブで発生したとき

この例はreact-navigationのbottomTabで発生したものです。
基本的にanrdoir/app/src/mainを修正したほうが正しい対応のように見えます。

1. TabComponentを作る

Keyboard.addListenerを使って、キーボードの判定を行い、都度制御しています。

import React, { Component } from 'react';
import { Platform, Keyboard } from 'react-native';
import { BottomTabBar } from 'react-navigation-tabs';

 // AndroidがキーボードによってtabBarを押し上げるのを防ぐ
// https://github.com/react-navigation/react-navigation-tabs/issues/16#issuecomment-402557546
export default class TabBarComponent extends Component<{}> {
  state = {
    visible: true,
  };

   componentDidMount() {
    if (Platform.OS === 'android') {
      this.keyboardEventListeners = [
        Keyboard.addListener('keyboardDidShow', this.visible(false)),
        Keyboard.addListener('keyboardDidHide', this.visible(true)),
      ];
    }
  }

   componentWillUnmount() {
    this.keyboardEventListeners &&
      this.keyboardEventListeners.forEach(eventListener =>
        eventListener.remove(),
      );
  }

   visible = visible => () => this.setState({ visible });

   render() {
    if (!this.state.visible) {
      return null;
    }
    return <BottomTabBar {...this.props} />;
  }
}

2. 1で作ったComponentをTabOptionにtabBarComponentを設定します

  {
    tabBarPosition: 'bottom',
    initialRouteName: PATH.XXX,
+   tabBarComponent: props => <TabBarComponent {...props} />,
    tabBarOptions: {
      activeTintColor: 'red',
      labelStyle: {},
      style: {},
    },
  },
