Unity3d截图保存到Android相册的实现
-----------------------------ultrasoon 季风原创---------------------------------------
1.Unity3d场景中先加入屏幕抓图功能:
Application.CaptureScreenshot("Screenshot.png");
这样Screenshot.png就存到了你的app沙盒中,请检查/sdcard/Android/data/com.ultrasoon.MyApp/,这个是我的app沙盒路径.
这个是第一步,之后还要保存到相册中。
2.unity中点击保存到相册按钮
unity部分代码:
1 public static AndroidJavaClass plugin; 2 3 4 void Awake () 5 { 6 7 if(Application.platform == RuntimePlatform.Android ) { 8 plugin = new AndroidJavaClass("com.ultrasoon.MyApp.Binding"); 9 } 10 } 11 void OnGUI() 12 { 13 if (GUI.Button(new Rect(20, 20, 100, 5), "save")) 14 { 15 //保存到相册,调用自己写的Binding插件 16 plugin.CallStatic("savebuttonClicked"); 17 18 } 19 }
3.Binding插件的实现.import对应的package
Binding.cs部分代码:
1 public static Context context; 2 3 // 保存到相册 4 public static void savebuttonClicked() { 5 6 //取得你XXXXXXXActivity的context.用自己的,不能用this,插件中调用静态的方法 7 context = XXXXXXXActivity.getApplicationContext(); 8 9 XXXXXXXActivity.runOnUiThread(new Runnable() { 10 public void run() { 11 // file:///sdcard/Android/data/com.ultrasoon.MyApp/files/Screenshot.png 12 Bitmap bitmap = Binding 13 .getDiskBitmap("/sdcard/Android/data/com.ultrasoon.MyApp/files/Screenshot.png"); 14 if (bitmap != null) { 15 16 MediaStore.Images.Media.insertImage( 17 context.getContentResolver(), bitmap, "myPhoto", ""); 18 context.sendBroadcast(new Intent( 19 Intent.ACTION_MEDIA_MOUNTED, 20 Uri.parse("file://" 21 + Environment.getExternalStorageDirectory()))); 22 Toast.makeText( 23 context, 24 " 恭喜你!照片已保存到你的相册中! ", Toast.LENGTH_SHORT).show(); 25 } 26 } 27 }); 28 29 } 30 31 // 读图 32 public static Bitmap getDiskBitmap(String url) { 33 34 Bitmap bitmap = null; 35 try { 36 File file = new File(url); 37 if (file.exists()) { 38 bitmap = BitmapFactory.decodeFile(url); 39 40 } 41 } catch (Exception e) { 42 43 } 44 return bitmap; 45 }
4.编译打包插件Binding,打包成jar,复制到unity的Asserts中下面的plugins目录里面。
OK了。
具体细节希望自己摸索!
