【GridView】在View中呈現GridView, 並有點選動作

  LayoutInflater factory = LayoutInflater.from(context);

  View view_img_mood = factory.inflate(R.layout.layout_img_mood, null);

  GridView gv_img_mood = (GridView) view_img_mood.findViewById(R.id.gv_img_mood);

 

  gv_img_mood.setAdapter(new Adapter_img_mood(this));

  //使GridView的點選有作用

  gv_img_mood.setOnItemClickListener(new OnItemClickListener()

        {

            public void onItemClick(AdapterView<?> parent, View v, int position, long id)

            {

             Toast.makeText(context, String.valueOf(position), Toast.LENGTH_SHORT).show();

             //使有底框色

             gv_img_mood.getChildAt(position).setBackgroundColor(getResources().getColor(R.color.paleyellow));

            }

        });

 

  new AlertDialog.Builder(this)

  .setView(view_img_mood)

        .setPositiveButton("ok", new DialogInterface.OnClickListener()

        {                      

            public void onClick(DialogInterface dialog, int whichButton)

            {

             Log.d("522", "ok");

            }

        })

        .setNegativeButton("cancel", new DialogInterface.OnClickListener()

        {                      

            public void onClick(DialogInterface dialog, int whichButton)

            {

             Log.d("522", "cancel");

            }

        })

        .show();
