更改gridView.SetChoiceModelListView.CHOICE\u MODE\u MULTIPLE；到

网格视图可以返回图像的id和相对于网格视图而不是相对于xml的位置

获取栅格视图中图像的id的步骤

gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
                Toast.makeText(getApplicationContext(), "id and position = "+id+" "+position, Toast.LENGTH_LONG).show();
            }

        });

gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
                Toast.makeText(getApplicationContext(), "id and position = "+id+" "+position, Toast.LENGTH_LONG).show();
            }

        });
