Question

我的每一行都有两个ImageView。如果我选择它们，它们将按预期工作，但是，它也会影响其他行。

这是代码。

    viewHolder.homeTeamLogo.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        pickYourProsModelsHashMap.put(scheduleList.get(position).getAway() + "vs" + scheduleList.get(position).getHome(), scheduleList.get(position).getHome());
        // if selected, make opacity full but change the awayTeamLogo to 50                

    }
});

viewHolder.awayTeamLogo.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        pickYourProsModelsHashMap.put(scheduleList.get(position).getAway() + "vs" + scheduleList.get(position).getHome(), scheduleList.get(position).getAway());
        // if selected, make opacity full but change the homeTeamLogo to 50     
                   }
});

在不影响列表中其他行的情况下执行此操作的正确方法是什么？

我确实在那里有if语句，如果我选择了hometeam，我会改变不透明度，反之亦然。我还添加了notifyDataSetChanged（）;它并没有影响它

这是我的整个getView

    @Override
    public View getView(final int position, View view, ViewGroup viewGroup){

        final ViewHolder viewHolder;
        //final ParseObject leagues = leaguesList.get(position);

        if (view == null) {
            view = LayoutInflater.from(activityContext).inflate(R.layout.schedule_list_view_pyp, null);
            viewHolder = new ViewHolder();
            viewHolder.awayTeam = (TextView) view.findViewById(R.id.awayTeam);
            viewHolder.awayTeamName = (TextView) view.findViewById(R.id.awayTeamName);
            viewHolder.homeTeam = (TextView) view.findViewById(R.id.homeTeam);
            viewHolder.homeTeamName = (TextView) view.findViewById(R.id.homeTeamName);
//            viewHolder.dateInformation = (TextView) view.findViewById(R.id.dateInformation);
            viewHolder.homeTeamLogo = (ImageView) view.findViewById(R.id.homeTeamLogo);
            viewHolder.awayTeamLogo = (ImageView) view.findViewById(R.id.awayTeamLogo);

            view.setTag(viewHolder);
        } else {
            viewHolder = (ViewHolder) view.getTag();
        }
        String month = scheduleList.get(position).getDate().substring(4, 6);
        String day = scheduleList.get(position).getDate().substring(6, 8);
        String year = scheduleList.get(position).getDate().substring(0, 4);

        home = scheduleList.get(position).getHome();
        away = scheduleList.get(position).getAway();

        viewHolder.homeTeam.setText(home);
        viewHolder.homeTeam.setTextColor(getContext().getResources().getColor(setColorOfTeam(home)));
        viewHolder.homeTeamName.setText(" " + scheduleList.get(position).getHomeTeamName().substring(0, 1).toUpperCase() + scheduleList.get(position).getHomeTeamName().substring(1).toLowerCase());
        viewHolder.awayTeam.setText(away);
        viewHolder.awayTeam.setTextColor(getContext().getResources().getColor(setColorOfTeam(away)));
        viewHolder.awayTeamName.setText(" " + scheduleList.get(position).getAwayTeamName().substring(0, 1).toUpperCase() + scheduleList.get(position).getAwayTeamName().substring(1).toLowerCase());
//        viewHolder.dateInformation.setText(scheduleList.get(position).getDay() + "  " + month + "/" + day + "/" + year + "  " + "at " + scheduleList.get(position).getTimeAMPM() + "M");

        viewHolder.homeTeamLogo.setImageDrawable(getContext().getResources().getDrawable(setTeamLogo(home)));
        viewHolder.awayTeamLogo.setImageDrawable(getContext().getResources().getDrawable(setTeamLogo(away)));



        viewHolder.homeTeamLogo.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                pickYourProsModelsHashMap.put(scheduleList.get(position).getAway() + "vs" + scheduleList.get(position).getHome(), scheduleList.get(position).getHome());
                // if selected, make opacity full but change the awayTeamLogo to 50

            }
        });

        viewHolder.awayTeamLogo.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                pickYourProsModelsHashMap.put(scheduleList.get(position).getAway() + "vs" + scheduleList.get(position).getHome(), scheduleList.get(position).getAway());
                // if selected, make opacity full but change the homeTeamLogo to 50
                }
        });

        return view;
    }

这是viewHolder

private static class ViewHolder {
    TextView awayTeam;
    TextView homeTeam;
    TextView awayTeamName;
    TextView homeTeamName;
    ImageView homeTeamLogo;
    ImageView awayTeamLogo;

}

试试这个。

要在按下它时保持listview项目的颜色，请在listview项目布局中包含以下行：

android:background="@drawable/bg_key"

然后在drawable文件夹中定义bg_key.xml，如下所示：

<?xml version="1.0" encoding="utf-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item 
        android:state_selected="true"
        android:drawable="@color/pressed_color"/>
    <item
        android:drawable="@color/default_color" />
</selector>

最后，将它包含在ListView onClickListener中：

listView.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position,long arg3) {
        view.setSelected(true);
        ... // Anything
    }
});

这样，任何时候都只会选择一个项目进行颜色选择。您可以使用以下内容在res / values / colors.xml中定义颜色值：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="pressed_color">#4d90fe</color>
    <color name="default_color">#ffffff</color>
</resources>

（ListView）选择一行中的图像，影响其他人
