Android 在同一文件中的类之间传递数据

我有一个服装

列表视图

内容标题和描述，我想获得单击行的标题，并在土司中显示它

我的适配器代码：

class SingleRow
{
String title;
String description;

SingleRow(String title, String description)
    {
    this.title = title;
    this.description = description;
    }
}
class Adapter extends BaseAdapter {


ArrayList<SingleRow> list;
Context context;

Adapter(Context c)
{
    context = c;
    list = new ArrayList<SingleRow>();
    Resources res = c.getResources();
    String[] titles = res.getStringArray(R.array.lwastitles);
    String[] descriptions = res.getStringArray(R.array.laws);

    for(int i=0;i<9;i++)
    {
        list.add(new SingleRow(titles[i],descriptions[i]));
    }
}
@Override
public int getCount() {
    return list.size();
}

@Override
public Object getItem(int i) {
    return list.get(i);
}

@Override
public long getItemId(int i) {
    return i;
}

@Override
public View getView(int i, View view, ViewGroup viewGroup) {
    LayoutInflater inflater= (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View row = inflater.inflate(R.layout.singlerow,viewGroup,false);
    TextView title = (TextView) row.findViewById(R.id.textView211);
    TextView description = (TextView) row.findViewById(R.id.textView112);
    title.setText(list.get(i).title);
    description.setText(list.get(i).description);
    return row;
}

}您可以执行以下操作：

list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
        SingleRow row = (SingleRow) adapterView.getItemAtPosition(position);
        Toast.makeText(getApplicationContext(), row.title,Toast.LENGTH_LONG).show();
    }
});

list.setOnItemClickListener（新的AdapterView.OnItemClickListener（）{
@凌驾
public void onItemClick（AdapterView AdapterView，视图视图，整型位置，长id）{
单行=（单行）adapterView.getItemAtPosition（位置）；
Toast.makeText（getApplicationContext（），row.title，Toast.LENGTH_LONG.show（）；
}
});

到底是什么问题？有问题的

MainActivity

的代码在哪里？你的项目click listener在哪里？@TedHopp我发布了主要活动，我想在Toast中显示选定的标题？只需使用第二个参数并从以下行获取标题：

TextView title=（TextView）view.findViewById（R.id.idOfTextView）@Geralt成功了！！非常感谢你！谢谢问题解决了我使用了以下代码TextView title=（TextView）view.findViewById（R.id.idOfTextView）；作者@Geralt
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
        SingleRow row = (SingleRow) adapterView.getItemAtPosition(position);
        Toast.makeText(getApplicationContext(), row.title,Toast.LENGTH_LONG).show();
    }
});
