Question

我想在Activity中创建一个带有几个项目的ListView（比如Item1 item2 item3 ..），当我点击（比如item1）时，它会进入下一个Activity，给我一个TextView（描述文本）和第2项和第3项的重复次数相同。我怎么能这样做？

Answer 1

您可以添加Listview setOnItemClickListener并获取文字说明。

list_view.setOnItemClickListener(new OnItemClickListener() {

   public void onItemClick(AdapterView<?> arg0, View arg1,int arg2,
        long arg3) {
          String description=alist.get(arg2);

        }
    });

Answer 2

检查此代码

    list_view.setOnItemClickListener(new OnItemClickListener() {

   public void onItemClick(AdapterView<?> arg0, View arg1,int arg2,
        long arg3) {
           TextView text = (TextView) view.findviewbyid(text view reference);
          String description=text .gettext();

        }
    });

Answer 3

使用

list_view.setOnItemClickListener(new OnItemClickListener()
{
    public void onItemClick(AdapterView<?> adapter, View view,int position, long arg3) 
    {
          String description = datalist.get(position);// datalist is the list of data which is use to create listview
          Intent intent = new Intent(FirstAcitivity.this, Activity2.class);
          intent.putExtra("description", description);// sending value to next activity

    }
});

在您的Activity2中（点击/点击用户移动后的目标活动）

String description = getIntent().getExtras().getString("description");// get description/value from activity which called this (Activity1)

如何阅读来自ListView的项目的描述文本？
