[FAQ11908][FSA]进入图库编辑图片保存后，去掉原有图片被覆盖的方法

来源：互联网发布：炉石传说知乎编辑：程序博客网时间：2024/04/27 06:47

[DESCRIPTION]

KK以及L版本上，在图库中编辑完图片后，保存时默认是覆盖原图的，如果不想覆盖原图，可以参考以下方法修改。

[SOLUTION]

KK版本：

请找到如下文件并进行如下尝试：
alps/packages/apps/Gallery2/src/com/android/gallery3d/filtershow/FilterShowActivity.java

Original：

 public void saveImage() {        if (mImageShow.hasModifications()) {            /// M: added for ConShots (never replace original conshot image with edited one) @{            Intent intent = getIntent();            if ((intent != null) && (intent.getBooleanExtra(NEED_SAVE_AS, false))) {                File dest = SaveImage.getNewFile(this, getSelectedImageUri());                SaveImage.saveImageAsACopy(this, dest);                return;            }            /// @}            // Get the name of the album, to which the image will be saved            File saveDir = SaveImage.getFinalSaveDirectory(this, mSelectedImageUri);            int bucketId = GalleryUtils.getBucketId(saveDir.getPath());            String albumName = LocalAlbum.getLocalizedName(getResources(), bucketId, null);            showSavingProgress(albumName);            mImageShow.saveImage(this, null);        } else {            done();        }    }

Modified：

     public void saveImage() {        if (mImageShow.hasModifications()) {            File saveDir = SaveImage.getFinalSaveDirectory(this, mSelectedImageUri);            int bucketId = GalleryUtils.getBucketId(saveDir.getPath());            String albumName = LocalAlbum.getLocalizedName(getResources(), bucketId, null);            showSavingProgress(albumName);            File dest = SaveImage.getNewFile(this, getSelectedImageUri());            SaveImage.saveImageAsACopy(this, dest);            return;        } else {            done();        }     }

L版本：

请找到如下文件并进行如下尝试：
alps/packages/apps/Gallery2/src/com/android/gallery3d/filtershow/FilterShowActivity.java

Original：

public void saveImage() {  if (mImageShow.hasModifications()) {     /// M: [BUG.ADD] disable backpress when saving image @{     showSavingProgress(mAlbumNameForSaving);     /// @}     /// M: [BUG.MARK] disable backpress when saving image @{     /*     // Get the name of the album, to which the image will be saved     File saveDir = SaveImage.getFinalSaveDirectory(this, mSelectedImageUri);     int bucketId = GalleryUtils.getBucketId(saveDir.getPath());     String albumName = LocalAlbum.getLocalizedName(getResources(), bucketId, null);     */     /// @}     /// M: [BUG.ADD] @{     Intent intent = getIntent();     if ((intent != null) && (intent.getBooleanExtra(NEED_SAVE_AS, false))) {     // show saving progress for continus shot pictures. @{     File dest = SaveImage.getNewFile(this, getSelectedImageUri());     SaveImage.saveImageAsACopy(this, dest);     return;  }  /// @}  /// M: [FEATURE.ADD] clear refocus Exif/db when edit photo @{  checkIfNeedToClearRefocusFlag();  /// @}  /// M: [BUG.MARK] disable backpress when saving image @{  // showSavingProgress(albumName);  /// @}  mImageShow.saveImage(this, null); } else {  done(); }}

Modified：

     public void saveImage() {        if (mImageShow.hasModifications()) {            File saveDir = SaveImage.getFinalSaveDirectory(this, mSelectedImageUri);            int bucketId = GalleryUtils.getBucketId(saveDir.getPath());            String albumName = LocalAlbum.getLocalizedName(getResources(), bucketId, null);            showSavingProgress(albumName);            File dest = SaveImage.getNewFile(this, getSelectedImageUri());            SaveImage.saveImageAsACopy(this, dest);            return;        } else {            done();        }     }

N版本:

在L版本修改的基础上，在/packages/apps/Gallery2/src/com/android/gallery3d/filtershow/tools/SaveImage.java中添加如下方法：

    public static void saveImageAsACopy(final FilterShowActivity filterShowActivity,File destination) {        Uri selectedImageUri = filterShowActivity.getSelectedImageUri();        Uri sourceImageUri = MasterImage.getImage().getUri();        Intent processIntent = ProcessingService.getSaveIntent(filterShowActivity,                MasterImage.getImage().getPreset(), destination,                selectedImageUri, sourceImageUri, true, 90, 1f, true);        filterShowActivity.startService(processIntent);        if (!filterShowActivity.isSimpleEditAction()) {            String toastMessage = filterShowActivity.getResources().getString(                    R.string.save_and_processing);            Toast.makeText(filterShowActivity,                    toastMessage,                    Toast.LENGTH_SHORT).show();        }    }

PS：以上修改，点击保存按钮后，回到PhotoPage界面，显示的是原图，如果想显示编辑后的图片，请修改如下Code：

KK版本：

1. PhotoPage.java

Original：

 private void launchPhotoEditor() {   MediaItem current = mModel.getMediaItem(0);   if (current == null || (current.getSupportedOperations()       & MediaObject.SUPPORT_EDIT) == 0) {     return;   }   Intent intent = new Intent(ACTION_NEXTGEN_EDIT);   /// M: [BUG.MODIFY] create new task when launch photo editor from camera    // gallery and photo editor use same task stack @{   //intent.setDataAndType(current.getContentUri(), current.getMimeType())   //      .setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);   intent.setDataAndType(current.getContentUri(), current.getMimeType())           .setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION                  | Intent.FLAG_ACTIVITY_CLEAR_TOP                  | Intent.FLAG_ACTIVITY_NEW_TASK);   /// @} ......}

Modified：

private void launchPhotoEditor() {   MediaItem current = mModel.getMediaItem(0);   if (current == null || (current.getSupportedOperations()       & MediaObject.SUPPORT_EDIT) == 0) {     return;   }   Intent intent = new Intent(ACTION_NEXTGEN_EDIT);   /// M: [BUG.MODIFY] create new task when launch photo editor from camera    // gallery and photo editor use same task stack @{   intent.setDataAndType(current.getContentUri(), current.getMimeType())         .setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);   /*intent.setDataAndType(current.getContentUri(), current.getMimeType())           .setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION                  | Intent.FLAG_ACTIVITY_CLEAR_TOP                  | Intent.FLAG_ACTIVITY_NEW_TASK);*/   /// @} ......}

2. SaveImage.java的如下函数，稍做修改：

如果 if(mPreviewImage ！= null) 这个分支被注释掉的话，请忽略此步；

否则，请按照如下方式修改：

Original：

public Uri processAndSaveImage(ImagePreset preset, boolean flatten,   int quality, float sizeFactor, boolean exit) {   ......   Uri savedUri = mSelectedImageUri;   if (mPreviewImage != null) {      if (flatten) {         Object xmp = getPanoramaXMPData(newSourceUri, preset);         ExifInterface exif = getExifData(newSourceUri);         long time = System.currentTimeMillis();         updateExifData(exif, time);         if (putExifData(mDestinationFile, exif, mPreviewImage, quality)) {            putPanoramaXMPData(mDestinationFile, xmp);            ContentValues values = getContentValues(mContext, mSelectedImageUri, mDestinationFile, time);            Object result = mContext.getContentResolver().insert(                Images.Media.EXTERNAL_CONTENT_URI, values);         }      } else {         ......     }   }  ...... return uri; }

Modified：

public Uri processAndSaveImage(ImagePreset preset, boolean flatten,   int quality, float sizeFactor, boolean exit) {   ......   Uri savedUri = mSelectedImageUri;   if (mPreviewImage != null) {      if (flatten) {         Object xmp = getPanoramaXMPData(newSourceUri, preset);         ExifInterface exif = getExifData(newSourceUri);         long time = System.currentTimeMillis();         updateExifData(exif, time);         if (putExifData(mDestinationFile, exif, mPreviewImage, quality)) {            putPanoramaXMPData(mDestinationFile, xmp);            // delete by mtk start            /*ContentValues values = getContentValues(mContext, mSelectedImageUri, mDestinationFile, time);            Object result = mContext.getContentResolver().insert(                Images.Media.EXTERNAL_CONTENT_URI, values);*/            // delete by mtk end         }                  // add by mtk start         savedUri = SaveImage.linkNewFileToUri(mContext, mSelectedImageUri,               mDestinationFile, time, !flatten);         // add by mtk end      } else {         ......      }   }    ......   //return uri;//delete by mtk   return savedUri; //add by mtk }

L版本：

只修改PhotoPage.java即可。

Original：

 private void launchPhotoEditor() {   ......   MediaItem current = mModel.getMediaItem(0);   if (current == null || (current.getSupportedOperations()       & MediaObject.SUPPORT_EDIT) == 0) {     return;   }   Intent intent = new Intent(ACTION_NEXTGEN_EDIT);   /// M: [BUG.MODIFY] create new task when launch photo editor from camera    // gallery and photo editor use same task stack @{   /*intent.setDataAndType(current.getContentUri(), current.getMimeType())     .setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);*/   intent.setDataAndType(current.getContentUri(), current.getMimeType())     .setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION       | Intent.FLAG_ACTIVITY_CLEAR_TOP       | Intent.FLAG_ACTIVITY_NEW_TASK);   /// @} ......}

Modified:

private void launchPhotoEditor() { ......  MediaItem current = mModel.getMediaItem(0);  if (current == null || (current.getSupportedOperations()      & MediaObject.SUPPORT_EDIT) == 0) {     return;  }  Intent intent = new Intent(ACTION_NEXTGEN_EDIT);  /// M: [BUG.MODIFY] create new task when launch photo editor from camera   // gallery and photo editor use same task stack @{  intent.setDataAndType(current.getContentUri(), current.getMimeType())    .setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);  /* intent.setDataAndType(current.getContentUri(), current.getMimeType())    .setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION       | Intent.FLAG_ACTIVITY_CLEAR_TOP       | Intent.FLAG_ACTIVITY_NEW_TASK);*/ /// @} ......}

M版本：

在L版本的修改基础上

1)将/packages/apps/Gallery2/src/com/android/gallery3d/app/PhotoPage.java中。

Original：

 private void launchPhotoEditor(){   .... ((Activity) mActivity).startActivityForResult(Intent.createChooser(intent, null).addFlags( Intent.FLAG_ACTIVITY_NEW_TASK), REQUEST_EDIT);overrideTransitionToEditor();}

Modified：

private void launchPhotoEditor(){  .... ((Activity) mActivity).startActivityForResult(Intent.createChooser(intent, null), REQUEST_EDIT);overrideTransitionToEditor();}

2)在/packages/apps/Gallery2/AndroidManifest.xml中

Original：

 <activity android:name="com.android.gallery3d.filtershow.FilterShowActivity" android:label="@string/title_activity_filter_show" android:theme="@style/Theme.FilterShow" android:taskAffinity="com.android.gallery3d.filtershow.FilterShowActivity" android:configChanges="keyboardHidden|orientation|screenSize" android:process=":filtershow" android:resizeableActivity="false">

Modified：

<activity android:name="com.android.gallery3d.filtershow.FilterShowActivity" android:label="@string/title_activity_filter_show" android:theme="@style/Theme.FilterShow" android:taskAffinity="com.android.gallery3d.filtershow.FilterShowActivity" android:configChanges="keyboardHidden|orientation|screenSize" android:resizeableActivity="false">

注意：

合入上面修改后，FilterShow与Gallery在process中，也就是说，如果FilterShow发生异常，整个Gallery有可能会crash掉，是否要这样修改，请仔细权衡后再合入。

以上修改方法本人在N版本上修改后报错：

01-05 10:45:49.606 3246 3246 E AndroidRuntime: FATAL EXCEPTION: main
01-05 10:45:49.606 3246 3246 E AndroidRuntime: Process: com.android.gallery3d, PID: 3246

需修改AndroidManifest.xml中如下service：

另外：由于添加了编辑图片后保存的功能需求，如FAQ11908这样修改。去掉了打开FitershowActivity 的Intent的Flag----Intent.FLAG_ACTIVITY_NEW_TASK。
而N版本上这边编辑图片的Activity又不支持分屏。
没有新建task导致编辑界面可以进入分屏模式，而此时编辑图片界面会出错。====> 那就没有别的办法了。因为如果新建task的话，PhotoPage这边无法获取到编辑这边返回的结果。这样导致编辑保存后，原图新图都保存了，但是返回到PhotoPage后，显示的是原图，而并非新图。

要不要合入FAQ11908就请贵司自行取舍了，这部分无法再优化了。
