public class MainActivity extends AppCompatActivity

{

  private List mList =new ArrayList();

  private SharedPreferences sp;

  private MyAdapter myAdapter;

  @Override

  protected void onCreate ( Bundle savedInstanceState )

  {

    super.onCreate ( savedInstanceState );

    setContentView ( R.layout.activity_main );

    initListView ( );

    initData();

  }

  //上下文菜单

  @Override

  public void onCreateContextMenu ( ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo )

  {

    menu.add ( "删除" );

  }

  @Override

  public boolean onContextItemSelected ( MenuItem item )

  {

    int position = menuInfo.position;

    MyData myData = mList.get ( position );

    String name = myData.getName ( );

    mList.remove ( position );

    SharedPreferences.Editor edit = sp.edit ( );

    edit.putInt ( name, 0);

    edit.commit ();

    myAdapter.notifyDataSetChanged ();

    return true;

  }

  private void initData ( )

  {

    sp =  getSharedPreferences("data",0);

    mList.clear ();

    for (int i=0;i

    {

      int anInt = sp.getInt ("0"+i,0 );

      if(anInt!=0)

      {

        mList.add ( new MyData ("0"+i,anInt ) );

      }

    }

    myAdapter.notifyDataSetChanged ();

  }

  private void initListView ( )

  {

    ListView mListView = ( ListView ) findViewById ( R.id.lv );

    myAdapter =  new MyAdapter();

    mListView.setAdapter ( myAdapter );

    registerForContextMenu (mListView);

  }

  class MyAdapter extends BaseAdapter

  {

    @Override

    public int getCount ( )

    {

      return mList.size ();

    }

    @Override

    public Object getItem ( int position )

    {

      return null;

    }

    @Override

    public long getItemId ( int position )

    {

      return 0;

    }

    @SuppressLint ( "ViewHolder" )

    @Override

    public View getView ( int position, View convertView, ViewGroup parent )

    {

      View layout = getLayoutInflater ( ).inflate ( R.layout.mainlistview, null );

      ImageView img = ( ImageView ) layout.findViewById ( R.id.mlv_img );

      TextView tv = ( TextView ) layout.findViewById ( R.id.mlv_tv );

        if ( imgId!= 0)

        {

          img.setVisibility ( View.VISIBLE );

          tv.setVisibility ( View.VISIBLE );

          img.setImageResource (  imgId );

          tv.setText ( mydata.getName () );

        }else

        {

          img.setVisibility ( View.GONE );

          tv.setVisibility ( View.GONE );

        }

      }

      return layout;

    }

  }

  @Override

  protected void onActivityResult ( int requestCode, int resultCode, Intent data )

  {

    initData();

    super.onActivityResult ( requestCode, resultCode, data );

  }

  public void btnClick ( View v )

  {

    Intent intent = new Intent ( this, SecondActivity.class );

    startActivityForResult ( intent, Constant.requestCode );

  }

}

接口：

interface Constant

{

  public final static int requestCode=01;

  public final static int[] TT={R.drawable.w1,R.drawable.w2,R.drawable.w3,

      R.drawable.w4,R.drawable.w5, R.drawable.w6,

      R.drawable.w7,R.drawable.w8,R.drawable.w9,

      R.drawable.w10, R.drawable.w11};

  public final static String[] SS={"01","02","03","04","05","06","07","08","09","10","11"};

}

添加功能界面类：

public class SecondActivity extends AppCompatActivity

{

  private SharedPreferences sp;

  @Override

  protected void onCreate(Bundle savedInstanceState)

  {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_second);

    initGridView();

  }

  //找GridView控件

  private void initGridView ( )

  {

     sp =  getSharedPreferences ( "data", 0 );

    GridView gv = ( GridView ) findViewById ( R.id.second_gv );

    MyGridAdapter myGridAdapter = new MyGridAdapter();

    gv.setAdapter ( myGridAdapter );

  }

  class MyGridAdapter extends BaseAdapter

  {

    @Override

    public int getCount ( )

    {

      return Constant.TT.length;

    }

    @Override

    public Object getItem ( int position )

    {

      return null;

    }

    @Override

    public long getItemId ( int position )

    {

      return 0;

    }

    @SuppressLint ( "ViewHolder" )

    @Override

    public View getView ( final int position, View convertView, ViewGroup parent )

    {

      View layout = getLayoutInflater ().inflate ( R.layout.secondgridview,null );

      ImageView img = ( ImageView ) layout.findViewById ( R.id.sgv_img );

      CheckBox cb = ( CheckBox ) layout.findViewById ( R.id.sgv_cb );

      img.setImageResource ( Constant.TT[position] );

      final int p=position;

      cb.setOnClickListener ( new View.OnClickListener ( )

      {

        @Override

        public void onClick ( View v )

        {

          SharedPreferences.Editor edit = sp.edit ( );

          edit.putInt ( "0"+p ,Constant.TT[p]);

          edit.commit ();

        }

      } );

      return layout;

    }

  }

  //返回首页页面

  public void btnBack(View v)

  {

    Intent intent = new Intent ( );

    setResult ( Constant.requestCode,intent );

    finish ();

  }

}

数据保存对象类：

public class MyData

{

  private String name;

  private int imgId;

  public MyData ( String name , int imgId )

  {

    this.name = name;

    this.imgId = imgId;

  }

  public String getName ( )

  {

    return name;

  }

  public int getImgId ( )

  {

    return imgId;

  }

  public void setName ( String name )

  {

    this.name = name;

  }

  public void setImgId ( int imgId )

  {

    this.imgId = imgId;

  }

}
