ViewPager+HorizontalScrollView简单使用

一、ScrollView，HorizontalScrollView的区别:

Android当中比较常用的两个布局容器：ScrollView和HorizontalScrollView，从字面意义上来看也是非常的简单的，ScrollView就是一个可以滚动的View，这个滚动的方向是垂直方向的，而HorizontalScrollView则是一个水平方向的可以滚动的View。

三、代码部分:

布局部分,HorizontalScrollView只能有一个子控件,这里我们就放的LinearLayout

Activity部分

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    private LinearLayout liner;
    private HorizontalScrollView hsv;
    //创建标题
    String[] title = {"影视","音乐","体育","新闻","幼教","记录","生活","养生","自然","社交","军事"};
    private TextView textView;
    private List list;
    private ViewPager pager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //加载组件
        liner = findViewById(R.id.Liner);
        hsv = findViewById(R.id.hsv);
        pager = findViewById(R.id.pager);

        //配置标题栏
        configTitle();
        //适配器
        pager.setAdapter(new MyFragmentPagerAdapter(getSupportFragmentManager()));
        //viewpager滑动监听
        addPagerListener();

    }
    
    //viewpager滑动监听
    private void addPagerListener() {

        pager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
            @Override
            public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

            }

            @Override
            public void onPageSelected(int position) {
                
                for (int i = 0; i < list.size(); i++) {
                    if(i==position){ //判断i是否等于当前轮播界面
                        TextView textView = list.get(i);
                        textView.setTextColor(Color.RED); //字体变红
                    }else{  //不是当前轮播界面的标题,为黑色
                        TextView textView = list.get(i);
                        textView.setTextColor(Color.BLACK);//字体变黑
                    }
                }

            }

            @Override
            public void onPageScrollStateChanged(int state) {

            }
        });
    }
    
    //初始化标题
    private void configTitle() {

        list = new ArrayList();
        for (int i = 0; i 

fragment实例部分,使用的简单方法(避免创建多次Fragment)

public class BaseFragment extends Fragment {


    //写一个静态方法,让外部可以调用,拿到参数
    public static Fragment getValues(String title){
        //创建自己的实例
        BaseFragment baseFragment = new BaseFragment();
        Bundle bundle = new Bundle();
        bundle.putString("title",title);
        //传值
        baseFragment.setArguments(bundle);
        //返回一个Fragment实例
        return baseFragment;

    }
    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        
        Bundle bundle = getArguments();
        TextView textView = new TextView(getActivity());
        //获取值
        textView.setText(bundle.getString("title"));
        textView.setTextSize(60);
        return textView;

    }

}
