如何获得由MediaStore.Images.Media路径 [英] How to get path by MediaStore.Images.Media

问题描述

我用低于code，得到所有的SD卡照片的位图。

I use below code to get the bitmap of all sd card photo.

String[] projection = {MediaStore.Images.Media._ID,MediaStore.Images.Media.DATA};  
Cursor cursor = managedQuery( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, projection, null, null, MediaStore.Images.Media._ID); 
int count = cursor.getCount();
int image_column_index = cursor.getColumnIndex(MediaStore.Images.Media._ID);
path = new String[count];
bm = new Bitmap[count];
for (int i = 0; i < count; i++) {
cursor.moveToPosition(i);
int id = cursor.getInt(image_column_index);
path[i] //How to get path
bt[i] = MediaStore.Images.Thumbnails.getThumbnail(getApplicationContext().getContentResolver(), id, MediaStore.Images.Thumbnails.MICRO_KIND, null);
}

我已经得到了所有照片的缩略图。 但我想要得到的绝对路径。 我应该在哪里修改？

I already get the thumbnail of all photo. But I want to get the absolute path. Where should I modify?

推荐答案

Images.ImageColumns.DATA 是路径

如何使用它：

int image_column_index = cursor.getColumnIndex(MediaStore.Images.Media._ID);
int image_path_index = cursor.getColumnIndex(MediaStore.Images.Media.DATA);
//added ... 
path[i] = cursor.getString(image_path_index);
