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;

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
{
    /**

                private static extern void _SavePhoto(string readAddr);
#endif

            }

            System.IO.File.WriteAllBytes(path_save, bytes);

            srcDataStream.dispose();
        }

        {
#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
