作业

1.首先用ListView展示列表。
2.再新建一个xml用来展示内容。
3.在主Activity中实现内容的传递。
在activity_main.xml的中如下：

在MainActivity中代码如下：package project.animalsound;

import android.app.ListFragment;

import android.os.Bundle;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.ListView;

public class TabFirst extends ListFragment {

  private AnimalListAdapter adapter = null;



@Override

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);



    adapter = new AnimalListAdapter (getActivity());

    setListAdapter(adapter); 

}



@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container,

        Bundle savedInstanceState) {

    View v = inflater.inflate(R.layout.tab_first, container, false);

    return v;

}



  @Override

  public void onListItemClick(ListView l, View v, int position, long id) {

       System.out.println("Click On List Item!!!");

       super.onListItemClick(l, v, position, id);

  }

}
