【react native】react-navigation安装（1）

安装主库

yarn add react-navigation

安装主库依赖的第三方库文件

yarn add react-native-gesture-handler
yarn add react-native-reanimated
yarn add react-native-safe-area-context
yarn add @react-native-community/masked-view
yarn add react-native-screens

根据需要引入各导航组件的库

yarn add react-navigation-stack
yarn add react-navigation-drawer
yarn add react-navigation-tabs

执行pod install

cd ios
pod install

为react-native-screens添加相关依赖

为了在Android上完成安装，还需要在android/app/build.gradle中为react-native-screens添加相关依赖：

implementation 'androidx.appcompat:appcompat:1.1.0-rc01'
implementation 'androidx.swiperefreshlayout:swiperefreshlayout:1.1.0-alpha02'

配置react-native-gesture-handler

为了在Android上能够使react-native-gesture-handler有效，需要修改MainActivity.java：

package com.reactnavigation.example;

import com.facebook.react.ReactActivity;
+ import com.facebook.react.ReactActivityDelegate;
+ import com.facebook.react.ReactRootView;
+ import com.swmansion.gesturehandler.react.RNGestureHandlerEnabledRootView;

public class MainActivity extends ReactActivity {

  @Override
  protected String getMainComponentName() {
    return "Example";
  }

+  @Override
+  protected ReactActivityDelegate createReactActivityDelegate() {
+    return new ReactActivityDelegate(this, getMainComponentName()) {
+      @Override
+      protected ReactRootView createRootView() {
+       return new RNGestureHandlerEnabledRootView(MainActivity.this);
+      }
+    };

在index.js or App.js中导入react-native-gesture-handler

import 'react-native-gesture-handler';`在这里插入代码片`
