示例1: queryRoots
import com.ipaulpro.afilechooser.R; //导入依赖的package包/类
@Override
public Cursor queryRoots(final String[] projection) throws FileNotFoundException {
// Create a cursor with either the requested fields, or the default
// projection if "projection" is null.
final MatrixCursor result = new MatrixCursor(projection != null ? projection
: DEFAULT_ROOT_PROJECTION);
// Add Home directory
File homeDir = Environment.getExternalStorageDirectory();
final MatrixCursor.RowBuilder row = result.newRow();
// These columns are required
row.add(Root.COLUMN_ROOT_ID, homeDir.getAbsolutePath());
row.add(Root.COLUMN_DOCUMENT_ID, homeDir.getAbsolutePath());
row.add(Root.COLUMN_TITLE, getContext().getString(R.string.internal_storage));
row.add(Root.COLUMN_FLAGS, Root.FLAG_LOCAL_ONLY | Root.FLAG_SUPPORTS_CREATE);
row.add(Root.COLUMN_ICON, R.drawable.ic_provider);
// These columns are optional
row.add(Root.COLUMN_AVAILABLE_BYTES, homeDir.getFreeSpace());
// Root.COLUMN_MIME_TYPE is another optional column and useful if you
// have multiple roots with different
// types of mime types (roots that don't match the requested mime type
// are automatically hidden)
