核心代码

packagecom.example.a2_;

importandroid.app.Activity;
importandroid.os.Bundle;
importandroid.view.View;
importandroid.widget.LinearLayout;
importandroid.widget.TextView;

importjava.util.Arrays;
importjava.util.List;

importbutterknife.ButterKnife;
importbutterknife.InjectView;

publicclassMainActivityextendsActivity{


@InjectView(R.id.gl1)
MyGridLayoutgl1;
@InjectView(R.id.gl2)
MyGridLayoutgl2;
@InjectView(R.id.activity_main)
LinearLayoutactivityMain;
//创建已订阅和为订阅的集合
privateListselect=Arrays.asList("北京","中国","国际","体育","生活","旅游","科技","军事","时尚","财经","育儿","汽车");
privateListunselect=Arrays.asList("娱乐","服饰","音乐","视频","段子","搞笑","科学","房产","名站");

@Override
protectedvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.inject(this);

//初始化数据
initData();
}


privatevoidinitData(){

gl1.setData(select);
gl2.setData(unselect);

gl1.setDragable(true);

//设置监听
gl1.setOnClickListener(newMyGridLayout.OnItemClickListener(){
@Override
publicvoidonItemClick(Viewv){
gl1.removeView(v);
//设置中间人
Strings=((TextView)v).getText().toString();
gl2.addItem(s);
}
});

gl2.setOnClickListener(newMyGridLayout.OnItemClickListener(){
@Override
publicvoidonItemClick(Viewv){
gl2.removeView(v);
//设置中间人
