Unity3d 复制文字到剪切板及存储图像到相册
游戏中里开发分享功能时用到两个小功能:1.复制一个链接到剪切板供在其他应用粘贴分享使用,2.保存一张二维码图像到相册供发送给其他应用用于分享。但是在unity中无法完成,需要分别开发相应的插件。
Android 部分:
使用android studio生成jar包(注意:其中
com.ztgame.ztmyseabed 为unity中playersettings里面设置的游戏bundle id
),
ClipboardTools.java 代码如下
package com.ztgame.ztmyseabed; //bundle id,建立工程时设置的包名 import android.app.Activity; import android.content.ClipboardManager; import android.content.ClipData; import android.content.ClipDescription; import android.content.Context; import android.content.Intent; import android.net.Uri; import android.provider.MediaStore; import android.util.Log; import java.io.File; import java.io.FileNotFoundException; import java.lang.reflect.Field; /** * Created by lanyantao on 2017/6/2. */ public class ClipboardTools { public static ClipboardManager clipboard = null; // 向剪贴板中添加文本 public void copyTextToClipboard(final Context activity, final String str) throws Exception { clipboard = (ClipboardManager) activity.getSystemService(Activity.CLIPBOARD_SERVICE); ClipData textCd = ClipData.newPlainText("data", str); clipboard.setPrimaryClip(textCd); } // 从剪贴板中获取文本 public String getTextFromClipboard() { if (clipboard != null && clipboard.hasPrimaryClip() && clipboard.getPrimaryClipDescription().hasMimeType(ClipDescription.MIMETYPE_TEXT_PLAIN)) { ClipData cdText = clipboard.getPrimaryClip(); ClipData.Item item = cdText.getItemAt(0); return item.getText().toString(); } return "null"; } public void SaveImageToGallery(final Context activity, final String path) { try{ Context context = activity; File file = new File(path); String url = ""; // 其次把文件插入到系统图库,(inserImgae中的参数没搞明白,第三个name这个参数不知道意义是什么,保存出来的的图像名称并不是这个name,而是系统按照时间生成的一个数字12496846464836.jpg这样,可否有人告知在下?) try { url = MediaStore.Images.Media.insertImage(context.getContentResolver(), file.getAbsolutePath(), file.getName(), null); } catch (FileNotFoundException e) { e.printStackTrace(); } // 最后通知图库更新 context.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://" + file.getPath()))); }catch(Exception e) { Log.e("SaveImageToGallery", e.getMessage()); } } } //release库打包指令:gradlew assembleRelease,在Terminal中执行即可
打包jar包的时候,我直接生成没有release包,都是debug的jar,如果要生成release的jar,
release库打包指令:gradlew assembleRelease,在Terminal中执行即可,首次执行需要下载一些工具包,会比较慢
也可以直接使用我自己打包的jar文件,路径:https://files.cnblogs.com/files/lan-yt/jar.zip
iOS 部分:
ShareUtil.h 头文件:
#import <Foundation/Foundation.h> #import <UIKit/UIKit.h> @ interface ShareUtilLib : NSObject extern "C" { /* 接口方法 */ void _SavePhoto(const char *readAddr); void _copyTextToClipboard(const char *textList); } - ( void ) imageSaved: ( UIImage *) image didFinishSavingWithError:( NSError *)error contextInfo: ( void *) contextInfo; @end
ShareUtil.mm 文件(ios中,.m文件为纯object-c语言,.mm文件为object-c和c++混合语言):
#import "ShareUtil.h" @implementation ShareUtilLib //将文本复制到IOS剪贴板 - (void)objc_copyTextToClipboard : (NSString *)text { UIPasteboard *pasteboard = [UIPasteboard generalPasteboard]; pasteboard.string = text; } - ( void ) imageSaved: ( UIImage *) image didFinishSavingWithError:( NSError *)error contextInfo: ( void *) contextInfo { if (error != nil) { NSLog(@"二维码保存错误"); } } @end extern "C" { static ShareUtilLib *iosClipboard; void _copyTextToClipboard(const char *textList) { NSString *text = [NSString stringWithUTF8String: textList] ; if(iosClipboard == NULL) { iosClipboard = [[ShareUtilLib alloc] init]; } [iosClipboard objc_copyTextToClipboard: text]; } void _SavePhoto(const char *readAddr) { NSString *strReadAddr = [NSString stringWithUTF8String:readAddr]; UIImage *img = [UIImage imageWithContentsOfFile:strReadAddr]; //NSLog([NSString stringWithFormat:@"w:%f, h:%f", img.size.width, img.size.height]); ShareUtilLib *instance = [ShareUtilLib alloc]; UIImageWriteToSavedPhotosAlbum(img, instance, @selector(imageSaved:didFinishSavingWithError:contextInfo:), nil); } }
unity中使用:
android平台jar文件放在Assets\Plugins\Android下,ios平台直接将上述两页代码放在Assets\Plugins\iOS下
然后在C#调用
using UnityEngine; using System.Runtime.InteropServices; namespace SDK.Lib { /** * @brief 分享:复制文本到剪切板,保存图像到相册 */ public class ShareUtil { #if UNITY_IOS /* Interface to native implementation */ [DllImport ("__Internal")] private static extern void _copyTextToClipboard(string text); [DllImport ("__Internal")] private static extern void _SavePhoto(string readAddr); #endif public ShareUtil() { } public void init() { } public void dispose() { } //复制文本到剪切板 public void copy_text_to_clipboard(string str) { #if UNITY_IOS this.copy_text_ios(str); #elif UNITY_ANDROID this.copy_text_android(str); #endif } private void copy_text_android(string str) { // "com.ztgame.ztmyseabed.ClipboardTools" : java中的类目录 + 类名 AndroidJavaObject androidObject = new AndroidJavaObject("com.ztgame.ztmyseabed.ClipboardTools"); AndroidJavaObject activity = new AndroidJavaClass("com.unity3d.player.UnityPlayer").GetStatic<AndroidJavaObject>("currentActivity"); if (activity == null) return; // 复制到剪贴板 androidObject.Call("copyTextToClipboard", activity, str); // 从剪贴板中获取文本 //string text = androidObject.Call<string>("getTextFromClipboard"); } private void copy_text_ios(string str) { #if UNITY_IOS _copyTextToClipboard(str); #endif } //保存图像到相册 public void save_img_to_album() { string srcpath = Application.persistentDataPath + "/MyQrCode.png"; Ctx.mInstance.mQrCodeMgr.savePic(srcpath);//先自己保存二维码图片,这个在自己代码中先生成图像 #if UNITY_IOS this.save_img_ios(srcpath); #elif UNITY_ANDROID this.save_img_android(srcpath); #endif } //unity中直接保存图片到sdcard,但是不会显示在相册中 private void save_img_android_by_unity(string srcpath) { MDataStream srcDataStream = new MDataStream(srcpath); srcDataStream.open(); byte[] bytes = srcDataStream.readByte(); string destination = "/sdcard/DCIM/ztgame"; //判断目录是否存在,不存在则会创建目录 if (!System.IO.Directory.Exists(destination)) { System.IO.Directory.CreateDirectory(destination); } string path_save = destination + "/myUFO.png"; //存图片 System.IO.File.WriteAllBytes(path_save, bytes); srcDataStream.dispose(); } private void save_img_android(string srcpath) { AndroidJavaObject androidObject = new AndroidJavaObject("com.ztgame.ztmyseabed.ClipboardTools"); AndroidJavaObject activity = new AndroidJavaClass("com.unity3d.player.UnityPlayer").GetStatic<AndroidJavaObject>("currentActivity"); if (activity == null) return; // 保存到相册 androidObject.Call("SaveImageToGallery", activity, srcpath); } private void save_img_ios(string srcpath) { #if UNITY_IOS _SavePhoto(srcpath); #endif } } }
注意:
iOS10以上的系统访问相册会崩溃,需要添加权限,参照 http://www.jianshu.com/p/e79156f80c22
另外:貌似有些andorid测试不成功,待研究
