使用Tablelayout完成RadioGroup+RadioButton效果

public class MainActivity extends AppCompatActivity {
	// Glide.with(this).load("gif地址").centerCrop().into(iv_gif);//没有加预加载
	//Glide.with(this).load("gif地址").)
	// .centerCrop().placeholder(R.drawable.ic_launcher).crossFade().into(iv_gif);//有预加载
	private ViewPager vp;
	private TabLayout tb;
	ArrayList<Fragment> arrayList;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
	super.onCreate(savedInstanceState);
	setContentView(R.layout.activity_main);
	initView();
	final String[] name ={"首页","分类","发现","购物车","我的"};
	final int[] pic = {R.drawable.sy,R.drawable.fenlei,R.drawable.faxian,R.drawable.gouwuche,R.drawable.wode};
	final int[] pic2 = {R.drawable.sy2,R.drawable.fenlei2,R.drawable.faxian2,R.drawable.gouwuche2,R.drawable.wode2};
	tb.setupWithViewPager(vp);
	arrayList = new ArrayList<>();
	arrayList.add(new BlankFragment());
	arrayList.add(new BlankFragment2());
	arrayList.add(new BlankFragment3());
	arrayList.add(new BlankFragment4());
	arrayList.add(new BlankFragment5()); //默认的适配器
	vp.setAdapter(new FragmentPagerAdapter(getSupportFragmentManager()) {
	@Override
	public Fragment getItem(int i) {
	return arrayList.get(i);
	}
	@Override
	public int getCount() {
	return arrayList.size();
	}
	});
	for (int i = 0; i < arrayList.size(); i++) {
	tb.getTabAt(i).setText(name[i]).setIcon(pic[i]);
	} //设置第一个默认选中效果
	tb.getTabAt(0).setIcon(pic2[0]);
	tb.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
	@Override
	public void onTabSelected(TabLayout.Tab tab) { //监听某个table被选中时的状态，进行要改变得设着
	tb.getTabAt(tab.getPosition()).setIcon(pic2[tab.getPosition()]);
	}
	@Override
	public void onTabUnselected(TabLayout.Tab tab) {
	tb.getTabAt(tab.getPosition()).setIcon(pic[tab.getPosition()]);
	}
