Question

我想从列表视图

中删除该项目

我的代码用于listview

this.lv1.setAdapter(new ArrayAdapter<String>(FindFilesByType.this, android.R.layout.test_list_item,Ringtones));
//          setListAdapter(new ArrayAdapter<String>(FindFilesByType.this, R.layout.main,
//                  Ringtones));
//          
            this.lv1.setOnItemClickListener(new OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> aView, View v,
                        int position, long id) {
                    currentPosition = position;
                    playRingtone(DIRECTORY+Ringtones.get(position));
                    Toast.makeText(FindFilesByType.this, "postion  "+DIRECTORY+Ringtones.get(position), Toast.LENGTH_LONG).show();
                GlobalVariable.SetstrEmail(DIRECTORY+Ringtones.get(position));
                GlobalVariable.SetcurrentPosition(position);
                }
            });

现在如何从中删除所选项目？

我在我的代码中使用了这样的东西，它可以删除列表中的多个项目

ListView lv_ArchivePartylist;

ArrayList<Parties> select_archived_party;

lv_ArchivePartylist = (ListView)findViewById(R.id.archive_ListView01);
            lv_ArchivePartylist.setOnItemClickListener(new OnItemClickListener()
                {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position,long id) {
                    // TODO Auto-generated method stub
                    if(view.findViewById(R.id.img_chkbox_archive).getVisibility()==TextView.GONE)
                    {
                        view.findViewById(R.id.img_chkbox_archive).setVisibility(TextView.VISIBLE);
                        Toast.makeText(ctx_archive, "Name="+archived_parties.get(position).getPartyTitle(), Toast.LENGTH_SHORT).show();
    select_archived_party.add(archived_parties.get(position));
    }
    }

});

然后我宣布了一个“删除”按钮，在它的On ClickListener方法上，它调用数据库中的代码（在你的情况下，它可能是Arraylist或数组）来删除在Arraylist“select_archived_party”中选择的项目。希望它有所帮助： - ）
