從媒體表中刪除：

private void delSourceFile(final String filePath) {
        ThreadFactory.getNormaPool().execute(new Runnable() {
            @Override
            public void run() {
                String[] retCol = {MediaStore.Audio.Media._ID};
                Cursor cur = mActivity.getContentResolver().query(
                        MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,
                        retCol,
                        MediaStore.MediaColumns.DATA + "=‘" + filePath + "‘", null, null);
                if (cur.getCount() == 0) {
                    return;
                }
                cur.moveToFirst();
                int id = cur.getInt(cur.getColumnIndex(MediaStore.MediaColumns._ID));
                LogUtil.getLog().e("id=" + filePath);
                cur.close();

                try {
                    Uri uri = ContentUris.withAppendedId(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,
                            id);
                    mActivity.getContentResolver().delete(uri, null, null);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
    }
