添加片段插入到反应天然视图(Add fragment into react-native view)

长话短说：我试图创建为AndroidPay的反应本地项目本机模块。 AndroidPay的集成是可能只使用的片段（其是在最后的“与AndroidPay买入”按钮）。因此，算法很简单，导出一个占位符反应本地的，包装在一个组成部分，在某些时候只是用它的ID添加片段到该占位符。所以，代码如下：

public class AndroidPayPlaceholderViewManager extends SimpleViewManager<FrameLayout>{
    public static final String REACT_CLASS = "AndroidPayButton";

    public AndroidPayPlaceholderViewManager(ReactApplicationContext context) {
        super();
    }

    @Override
    public String getName() {
        return REACT_CLASS;
    }

    @Override
    protected FrameLayout createViewInstance(ThemedReactContext reactContext) {
        return (FrameLayout) LayoutInflater.from(reactContext).inflate(R.layout.android_pay_frg_placeholder, null);
    }
}

android_pay_placeholder.xml

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center_horizontal">
    <FrameLayout
        android:id="@+id/android_pay_placeholder"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="center_horizontal">
    </FrameLayout>
</FrameLayout>

JS部件的包装材料

import {View, requireNativeComponent} from 'react-native';
import React, {Component} from 'react';
import {NativeModules, findNodeHandle} from 'react-native';
import {isAndroid} from '../utils';


let iface = {
    propTypes: {
        ...View.propTypes, // include the default view properties
        foo: String
    }
};

let AndroidPayButtonNative = requireNativeComponent('NewStoreAndroidPayButton', iface);
console.log('AndroidPayButtonNative: ', AndroidPayButtonNative);
let AndroidPayModule = isAndroid() ? NativeModules.NewStoreAndroidPay : null;

class AndroidPayButton extends Component {
    state = {
        loaded: false
    };

    componentDidMount() {
        AndroidPayModule.loadFragment();
    }

    render() {
        return (
            <AndroidPayButtonNative {...this.props} />
        );
    }
}

export {AndroidPayButton};

机器人本机模块，其是负责加载片段的

public class AndroidPayModule extends ReactContextBaseJavaModule implements ActivityEventListener, LifecycleEventListener {
....
@ReactMethod
    public void loadFragment(int placeholderId) {
        ...
        WalletFragment mWalletFragment = WalletFragment.newInstance(...);


        // add Wallet fragment to the UI
        getCurrentActivity().getFragmentManager().beginTransaction()
                .add(R.id.android_pay_placeholder, mWalletFragment)
                .commit();

        // [END params_builder]
    }
....
}

所以，当我添加了“占位符”查看屏幕，我可以看到它，甚至与LayoutInspector检查，该ID是正确的：

而结果是，我总是得到是例外：

java.lang.IllegalArgumentException: No view found for id 0x7f0d00a6 (com.qwerty.playground:id/android_pay_placeholder) for fragment WalletFragment{388fd9c #0 id=0x7f0d00a6}

所以，球员，任何想法，为什么FragmentManager不能只找到这肯定存在一个观点，也许你们有人做这一招用的片段和应对本地和成功？任何帮助，将不胜感激！谢谢！
