启动活动在单击列表视图项后？ [英] Starting an activity after a listview item is clicked?

问题描述

好了，所以我有一个应用程序有一些教程。（约20）（每啧啧只是一些文字填写的活动画面）

Okay, so I have an app with a few tutorials.(around 20) (Each tut is just some text filled in an activity screen)

我要创建的主菜单上的一个按钮，它指向包含所有教程活动的名称列表视图活动 - 按字母排序

I want to create a button on the main menu, that points to a listview activity containing the names of all the tutorial's activities - alphabetically.

不完美的导航，我知道。但我认为这是最好的快速和简单的解决方案，直到我了解更多信息。

Not perfect navigation, I know. But I think it's the best quick and easy solution till I learn more.

下面的问题：我只想说找出单击的ListView项，并把正常的onclick（）开辟了相应的教程活动

Here's the problem: I just want to say find out which listview item was clicked, and put a normal onclick() which opens up the corresponding tutorial activity.

究竟怎样设置列表视图？我知道正常的onclick是如何工作的......但如何与ListView项呢？

How exactly do I set up the listview ? I know how the normal onclick works... but how to do it with a listview item ?

我来这里从 https://groups.google.com/forum/ ＃！论坛/ Android的开发者

它说，我们可以在这里问初学者问题，但人们似乎宁愿花了precious暂时均值。是不是真的值得吗？如果你知道请帮助我。 （A code例子将是巨大的，但任何帮助将是AP preciated）

It said we can ask beginner questions here, but people seem to rather spend their precious time being mean. Is it really worth it ? If you know pls help me out. (A code example would be great, but any help would be appreciated)

推荐答案

这个例子显示了如何初始化一个ListView名为list1的，并在布局文件中定义的水库\\布局\\ main.xml中

This example shows how to initialize a listView named list1 and defined in a layout-file res\layout\main.xml

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);
    ListView list = (ListView) findViewById(R.id.list1);
    String[] days = { "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday" };
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, days);
    list.setAdapter(adapter);

    /**
      * go to next activity for detail image
      */
    list.setOnItemClickListener(new OnItemClickListener() {

       @Override
       public void onItemClick(AdapterView<?> parent, View v, final int position, long id) {
           System.out.println(v+position);
           Intent intent = new Intent(A.this, B.class);
           startActivity(intent);
        }
    });
}
