实现

List<Marker> list_marker = new ArrayList<>();
boolean isShowMarker = true;


@Override
public boolean onCreateOptionsMenu(Menu menu) {
	String[] sm = { "显隐信息", "显隐照片", "截图", "分享", "重命名", "删除", "退出" };
	for (int i=0; i<sm.length; i++) {
		menu.add(0, i, i, sm[i]);
	}
	return true;
}

@Override
public boolean onPrepareOptionsMenu(Menu menu) {
	MenuItem item = menu.findItem(1);
    if (isShowMarker)
        item.setTitle("隐藏照片");
    else
        item.setTitle("显示照片");
	return true;
}
	

@Override
public boolean onOptionsItemSelected(MenuItem item) {
	int item_id = item.getItemId();
	switch (item_id) {
		...
        case 1:
            isShowMarker = !isShowMarker;
            for (int i=0; i<list_marker.size(); i++) {
                Marker marker = list_marker.get(i);
                marker.setVisible(isShowMarker);
            }
            break;
		...
	}
}

void addPhotoMarker() {
	...
	list_marker.clear();
	for (int i = 0; i < list_photo_LatLng.size(); i++) {
		...
		OverlayOptions overlay = new MarkerOptions().position(list_photo_LatLng.get(i)).icon(bitmap4).extraInfo(bundle);
        Marker marker = (Marker) mBaiduMap.addOverlay(overlay);
