   List people = new ArrayList() ;

   EditText editinput;

   ListView listview;

   Adapter adapter;

   @Override

   protected void onCreate(Bundle savedInstanceState) {

     super.onCreate(savedInstanceState);

     setContentView(R.layout.activity_main);

     editinput = (EditText)findViewById(R.id.edit);

    listview = (ListView)findViewById(R.id.ydlist);

     initdata();

    adapter = new Adapter( people);

     listview.setAdapter(adapter);

     editinput.addTextChangedListener(new watcher());

   }

   void initdata(){

     people.add(new People("张三","1374456"));

     people.add(new People("张三小子", "12444455"));

        }

        TextView tv1 = (TextView) convertView.findViewById(R.id.ydtext1);

        TextView tv2 = (TextView) convertView.findViewById(R.id.ydtext2);

        tv1.setText(p.getName());

        tv2.setText(p.getPhome());

        return convertView;

      }

  

  

  

    }

   public class People {

     private String Name ;

      private String Phome;

  

  

  

      public String getName() {

       return Name;

     }

  

  

  

     public void setName(String name) {

       Name = name;

     }

  

  

  

     public String getPhome() {

       return Phome;

     }

  

  

  

     public void setPhome(String phome) {

       Phome = phome;

     }

  

  

  

     public People(String name,String phone){

       super();

       this.Name = name;

       this.Phome = phone;

     }

   }

 }

xml的代码：

  xmlns:tools="http://schemas.android.com/tools"

  android:layout_width="match_parent"

  android:layout_height="match_parent"

  tools:context=".MainActivity" >

  

    android:id="@+id/edit"

    android:layout_width="wrap_content"

    android:layout_height="wrap_content"

    android:layout_alignParentLeft="true"

    android:layout_alignParentTop="true"

    android:layout_marginLeft="82dp"

    android:ems="10" >

    

  

  

    android:id="@+id/ydlist"

    android:layout_width="match_parent"

    android:layout_height="match_parent"
