我的gridview中有imageview.我想禁用在android的gridview中点击的当前项目/图像.我无法做到这一点.如何做到这一点？这是一个代码 -

        @Override
        public void onItemClick(AdapterView<?> arg0, View v, int no,long lg) {
            // TODO Auto-generated method stub

            final AlertDialog.Builder alert = new AlertDialog.Builder(MainActivity.this);
            id=no;

            final EditText input = new EditText(MainActivity.this);
            alert.setView(input);

            alert.setPositiveButton("Check", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {

            String value = input.getText().toString();

              AlertDialog.Builder alert1 = new AlertDialog.Builder(MainActivity.this);

                    });

              }
              else
              {

              }
            }
            });

        }
    });

您需要一个自定义适配器.

覆盖方法

ListAdapter.isEnabled(int position)

并覆盖ListAdapter.areAllitemsEnabled()以返回false.

完全禁用在GridView的UI中单击以及选择图形.
