listview.setOnItemClickListener(new OnItemClickListener(){

            @Override
            public void onItemClick(AdapterView<?> parent,View view,int position,long id)
            {
                if(position==1){
                Intent intent=new Intent("com.kunge.myapp.BUTTON1");
                intent.addCategory("android.intent.category.MYCATEGORY");
                startActivity(intent);
                }
            }
        });

能编译，但按下ListView中的第二个item时app停止运行
