            View layout = inflater
                    .inflate(R.layout.alertdiaolog_main, null);
            GridView gridView2 = (GridView) layout
                    .findViewById(R.id.alert_gridview);

            gridView2.setAdapter(new AlertImageAdapter(getActivity()));
            gridView2.setOnItemClickListener(new OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View v,
                        int position, long id) {  

                }
            });

            builder = new AlertDialog.Builder(mContext);
            builder.setNegativeButton("Close",
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int id) {

                            dialog.cancel();
                        }
                    });

            builder.setView(layout); 
            builder.show();



        }
    });

我有这个代码。 当您单击gridView项时。 还会显示带有dialogview的alertdialog。 如果用户单击gridView2项，如何关闭Alertdialog？

Answer 1

当你建立AlertDialog使用AlertDialog Builder

 AlertDialog.Builder builder = new AlertDialog.Builder(mContext);

使用create获取AlertDialog的实例

Dialog dialog = builder.create();

因此，在需要时，您可以致电

dialog.dismiss();
