如何用网站做课件优秀网站设计欣赏图片

最近游戏中需要加上复制粘贴的功能，这个时候就涉及到安卓原生层的东西。步骤如下：

复制功能

ts代码

调用代码，在需要复制的地方调用即可。

     public static copyToClipBoard(str) {if (sys.platform == sys.Platform.ANDROID) {PlatformMgr.callNativeFn("copyToClipboard", str);}}

    static async callNativeFn(funcName: string, jsonMsg?: string): Promise<{ msg: string, isSucc: boolean }> {if (sys.platform != sys.Platform.ANDROID) // TODO: web 暂时只支持 Android 调用returnlet fn = PlatformMgr.Ins._platformIns[funcName]if (typeof (fn) == "function") { // 支持重写方法return await fn(funcName, jsonMsg)} else {return await PlatformMgr.Ins._platformIns.callNativeFn(funcName, jsonMsg)}}

import { NativeMgr } from "../../module/native/NativeMgr";export class PlatformBase {// 最终调用 natvie 接口async callNativeFn(funcName: string, jsonMsg?: string) {return new Promise<{ msg: string, isSucc: boolean }>((resolve) => {NativeMgr.Ins.callNativeFunc((msg: string, isSucc: boolean) => {resolve({ msg: msg, isSucc: isSucc })}, funcName, jsonMsg)})}
}

java代码

放在你自己的逻辑中，放在AppActivity.java中即可。前面需要import相关的库文件

import android.content.ClipData;
import android.content.ClipboardManager;
import android.content.Context;

调用代码:

public static void copyToClipboard(String textToCopy) {// 获取剪贴板管理器ClipboardManager clipboardManager = (ClipboardManager) getActivity().getApplicationContext().getSystemService(Context.CLIPBOARD_SERVICE);// 创建 ClipData 对象ClipData clipData = ClipData.newPlainText("Copied Text", textToCopy);// 将 ClipData 设置到剪贴板clipboardManager.setPrimaryClip(clipData);try {JSONObject jsonobj = new JSONObject();jsonobj.put("type", "copyText");jsonobj.put("code", "1");Log.d("copyToClipboard",  jsonobj.toString());String str = String.format("NativeAndroid.javaCallback(\'%s\')", jsonobj.toString());
//                    CocosJavascriptJavaBridge.evalString(str);callJsGlobalFunc(str);} catch (Exception e) {}}

获取剪切板内容

ts代码

     public static copyToClipBoard(str) {if (sys.platform == sys.Platform.ANDROID) {let android = new AndroidNative();android.getText("getText");}}

export class AndroidNative implements INativeCaller {getText(funcName: string, jsonMsg: string = "{}") {   let getText = native.reflection.callStaticMethod(this._activityName, funcName, "()Ljava/lang/String;");console.log("剪切板内容")}
}

java代码

    public static String getText(){ClipboardManager clipboard = (ClipboardManager) getActivity().getApplicationContext().getSystemService(Context.CLIPBOARD_SERVICE);ClipData clip = clipboard.getPrimaryClip();if (clip != null && clip.getItemCount() > 0) {Log.d("剪切板内容 = ",clip.getItemAt(0).coerceToText(getActivity().getApplicationContext()).toString());return clip.getItemAt(0).coerceToText(getActivity().getApplicationContext()).toString();}return null;}
