如何通過MediaStore.Images.Media獲取路徑

我使用下面的代碼獲取所有sd卡照片的位圖。如何通過MediaStore.Images.Media獲取路徑

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); 
}

我已經得到所有照片的縮略圖。但我想獲得絕對路徑。我應該在哪裏修改？

Images.ImageColumns.DATA是路徑

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);

關於如何使用它的更多細節？ – brian 2012-01-05 03:11:52

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）; //新增 – idiottiger 2012-01-05 03:16:11

謝謝！我知道了！ – brian 2012-01-05 03:18:07

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 

    if (resultCode == RESULT_OK) { 

      if (requestCode == yourRequestCode) { 
        currImageURI = data.getData(); 
      } 
    } 
} 

// Convert the image URI to the direct file system path 
public String getRealPathFromURI(Uri contentUri) { 

    String [] proj={MediaStore.Images.Media.DATA}; 
    Cursor cursor = managedQuery(contentUri, 
        proj, // Which columns to return 
        null,  // WHERE clause; which rows to return (all rows) 
        null,  // WHERE clause selection arguments (none) 
        null); // Order-by clause (ascending by name) 
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); 
    cursor.moveToFirst(); 

    return cursor.getString(column_index); 
}

在最新的OS managed query是如此不贊成使用

yourActivity.getContentResolver().query代替它，這兩個使用相同的參數
