android Uri获取真实路径转换成File的方法

Uri uri = data.getData();

String[] proj = { MediaStore.Images.Media.DATA };

Cursor actualimagecursor = managedQuery(uri,proj,null,null,null);

int actual_image_column_index = actualimagecursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);

actualimagecursor.moveToFirst();

String img_path = actualimagecursor.getString(actual_image_column_index);

File file = new File(img_path);

以下是4.2.2之后，managedQuery方法被废弃后的解决方案：

public String getRealPathFromURI(Uri contentUri) { String res = null; String[] proj = { MediaStore.Images.Media.DATA }; Cursor cursor = getContentResolver().query(contentUri, proj, null, null, null); if(cursor.moveToFirst()){; int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); res = cursor.getString(column_index); } cursor.close(); return res; }
