uriForCapture = content://com.android.providers.media.documents/document/video%3A98
uriForCapture = content://media/external/video/media/98
针对这2中uri第二种通过查多媒体数据库很容易得到文件path,类似:uriString = /storage/emulated/0/DCIM/Camera/***.mp4
但是第一种不能直接查询到。
可以尝试以下方法:
private String getPathFromDocmentsUri(Context ctx,Uri docUri) {
String imagePath = null;
if (DocumentsContract.isDocumentUri(ctx, docUri)) {
String docId = DocumentsContract.getDocumentId(docUri);
if ("com.android.externalstorage.documents".equals(docUri.getAuthority())) {
String dir = docId.split(":")[0];
String selec= docId.split(":")[1];
imagePath = "/storage/"+dir+"/"+selec;
return imagePath;
}else if ("com.android.providers.media.documents".equals(docUri.getAuthority())) {
String id = docId.split(":")[1];
//String selection = MediaStore.Video.Media._ID + "=" + id;
imagePath = getPathFromDoc(MediaStore.Video.Media.EXTERNAL_CONTENT_URI.toString()+"/"+id);
} else if ("com.android.providers.downloads.documents".equals(docUri.getAuthority())) {
Uri contentUri = ContentUris.withAppendedId(
Uri.parse("content://downloads/public_downloads"),
Long.valueOf(docId));
imagePath = getPathFromDoc(contentUri.toString());
}
}
return imagePath;
}
private String getPathFromDoc(String docUri) {
String imagePath = null;
Log.d(TAG, "getPathFromDoc ,imageUrl= " + docUri);
Uri uri = Uri.parse(docUri);
String[] proj = { MediaStore.Images.Media.DATA };
Cursor imageCursor = mContext.getContentResolver().query(uri, proj, null, null, null);
if (imageCursor != null) {
if (imageCursor.moveToFirst()) {
int image_column_index = imageCursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
imagePath = imageCursor.getString(image_column_index);
}
imageCursor.close();
}
return imagePath;
}
