Question

我的数据库数据存储在列表视图中，当我点击其中一个列表视图时，如何根据参数“position”获取每个项目？

lv.setOnItemClickListener(new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        // TODO Auto-generated method stub
    }
});

Answer 1

你可以通过 - ：

来做到

messagesContainer.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        switch (position){
           case 0:
            break;
          case 1:
            break;

        }
    }
});

但是当我们在listview中有很多项目时，这将是复杂的。感谢

如果您在listview中设置数据库数据，如下所示

ArrayAdapter<Object> mDatabaseData = new ArrayAdapter<Object>(this,android.R.layout.simple_expandable_list_item_2, array);
lv.setAdapter(mDatabaseData);

然后您可以根据参数“position”获取每个项目，如下所示

lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
    int position, long id) {
  // When clicked, get data for selected position
   Object selectedItem=mDatabaseData.get(position);
   }
});

关于setOnItemClickListener（new OnItemClickListener（）
