我通过以下代码解决了这个问题：
当我们从谷歌照片应用程序获取图像时，我们需要为图像提供 realPath
//get Path
@TargetApi(Build.VERSION_CODES.KITKAT)
public String getRealPathFromURI(final Uri uri) {
final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
// DocumentProvider
if (isKitKat && DocumentsContract.isDocumentUri(context, uri)) {
// ExternalStorageProvider
if (isExternalStorageDocument(uri)) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
if ("primary".equalsIgnoreCase(type)) {
return Environment.getExternalStorageDirectory() + "/" + split[1];
}
}
// DownloadsProvider
else if (isDownloadsDocument(uri)) {
final String id = DocumentsContract.getDocumentId(uri);
final Uri contentUri = ContentUris.withAppendedId(
Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));
return getDataColumn(contentUri, null, null);
}
// MediaProvider
else if (isMediaDocument(uri)) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
Uri contentUri = null;
if ("image".equals(type)) {
contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
} else if ("video".equals(type)) {
contentUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
} else if ("audio".equals(type)) {
contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
}
final String selection = "_id=?";
final String[] selectionArgs = new String[]{
split[1]
};
return getDataColumn(contentUri, selection, selectionArgs);
}
}
// MediaStore (and general)
else if ("content".equalsIgnoreCase(uri.getScheme())) {
// Return the remote address
if (isGooglePhotosUri(uri))
return uri.getLastPathSegment();
return getDataColumn(uri, null, null);
}
// File
else if ("file".equalsIgnoreCase(uri.getScheme())) {
return uri.getPath();
} else
return getRealPathFromURIDB(uri);
return null;
}
/**
* Gets real path from uri.
*
* @param contentUri the content uri
* @return the real path from uri
*/
private String getRealPathFromURIDB(Uri contentUri) {
Cursor cursor = context.getContentResolver().query(contentUri, null, null, null, null);
if (cursor == null) {
return contentUri.getPath();
} else {
cursor.moveToFirst();
int index = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
String realPath = cursor.getString(index);
cursor.close();
return realPath;
}
}
/**
* Gets data column.
*
* @param uri the uri
* @param selection the selection
* @param selectionArgs the selection args
* @return the data column
*/
public String getDataColumn(Uri uri, String selection,
String[] selectionArgs) {
Cursor cursor = null;
final String column = "_data";
final String[] projection = {
column
};
try {
cursor = context.getContentResolver().query(uri, projection, selection, selectionArgs,
null);
if (cursor != null && cursor.moveToFirst()) {
final int index = cursor.getColumnIndexOrThrow(column);
return cursor.getString(index);
}
} finally {
if (cursor != null)
cursor.close();
}
return null;
}
/**
* Is external storage document boolean.
*
* @param uri The Uri to check.
* @return Whether the Uri authority is ExternalStorageProvider.
*/
public boolean isExternalStorageDocument(Uri uri) {
return "com.android.externalstorage.documents".equals(uri.getAuthority());
}
/**
* Is downloads document boolean.
*
* @param uri The Uri to check.
* @return Whether the Uri authority is DownloadsProvider.
*/
public boolean isDownloadsDocument(Uri uri) {
return "com.android.providers.downloads.documents".equals(uri.getAuthority());
}
/**
* Is media document boolean.
*
* @param uri The Uri to check.
* @return Whether the Uri authority is MediaProvider.
*/
public boolean isMediaDocument(Uri uri) {
return "com.android.providers.media.documents".equals(uri.getAuthority());
}
/**
* Is google photos uri boolean.
*
* @param uri The Uri to check.
* @return Whether the Uri authority is Google Photos.
*/
public boolean isGooglePhotosUri(Uri uri) {
return "com.google.android.apps.photos.content".equals(uri.getAuthority());
}
现在在 onActivityResult 方法中：
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK) {
if (requestCode == ChoosePhoto.CHOOSE_PHOTO_INTENT) {
if (data != null && data.getData() != null) {
handleGalleryResult(data);
} else {
handleCameraResult(choosePhoto.getCameraUri());
}
} else if (requestCode == ChoosePhoto.SELECTED_IMG_CROP) {
mImgProfile.setImageURI(choosePhoto.getCropImageUrl());
}
}
}
现在在 handleGalleryResult 方法中：
public void handleGalleryResult(Intent data) {
try {
cropPictureUrl = Uri.fromFile(createImageTempFile(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)));
String realPathFromURI = FileUtil.getRealPathFromURI(data.getData());
File file = new File(realPathFromURI);
if(file.exists()) {
if(currentAndroidDeviceVersion>23){
cropImage(FileProvider.getUriForFile(mContext, mContext.getApplicationContext().getPackageName() + ".provider", file), cropPictureUrl);
}else{
cropImage(Uri.fromFile(file), cropPictureUrl);
}
} else
cropImage(data.getData(), cropPictureUrl);
} catch (IOException e) {
e.printStackTrace();
}
}
创建图像临时文件：
@SuppressLint("SimpleDateFormat")
public File createImageTempFile(File filePathDir) throws IOException {
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
return File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
filePathDir /* directory */
);
}
