我正在尝试制作一个仅在图库视图中显示特定文件夹中的图像的小应用程序。我找到了一些例子，但每一个最终只显示一张图像。我将在下面发布的这个例子是一个很好的帮助，它几乎完全符合我的要求，我只需要更改它以显示来自特定文件夹的图像，而不是所有文件夹。我已经为此尝试了几天，但我似乎没有添加正确的代码。我觉得这是一件我也想念的非常简单的事情。任何帮助将不胜感激！

public class AndroidCustomGallery extends Activity {

    private int count;
    private Bitmap[] thumbnails;
    private boolean[] thumbnailsselection;
    private String[] arrPath;
    private ImageAdapter imageAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        final String[] columns = { MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID };

                final String orderBy = MediaStore.Images.Media._ID;

                Cursor  imagecursor = getContentResolver().query(
                        MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns, null,        
                        null, orderBy);




                int image_column_index = imagecursor.getColumnIndex(MediaStore.Images.Media._ID);          
                this.count = imagecursor.getCount();        
                this.thumbnails = new Bitmap[this.count];       
                this.arrPath = new String[this.count];  
                this.thumbnailsselection = new boolean[this.count];

                for (int i = 0; i < this.count; i++) {

                    imagecursor.moveToPosition(i);

                    int id = imagecursor.getInt(image_column_index);        
                    int dataColumnIndex = imagecursor.getColumnIndex(MediaStore.Images.Media.DATA); 

                  thumbnails[i] = MediaStore.Images.Thumbnails.getThumbnail(        
                            getApplicationContext().getContentResolver(), id,       
                            MediaStore.Images.Thumbnails.MICRO_KIND, null);     

                    arrPath[i]= imagecursor.getString(dataColumnIndex);

                }

                GridView imagegrid = (GridView) findViewById(R.id.PhoneImageGrid);      
                imageAdapter = new ImageAdapter();      
                imagegrid.setAdapter(imageAdapter);     
                imagecursor.close();

弄清楚了！以下是任何想要做类似事情的人的粘贴代码。

Cursor imagecursor = getContentResolver().query( MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                        columns, 
                        MediaStore.Images.Media.DATA + " like ? ",
                        new String[] {"%/yourfoldername/%"},  
                        null);
