1.MyHorizontalScrollView的程式碼

public class MyHorizontalScrollView extends HorizontalScrollView {
    //另一個HorizontalScrollView
MyHorizontalScrollView otherHsv;

    public MyHorizontalScrollView(Context context) {
        this(context, null);
    }

    public MyHorizontalScrollView(Context context, AttributeSet attrs) {
        super
 
(context, attrs);
    }


    //滑動時呼叫
@Override
protected void onScrollChanged(int l, int t, int oldl, int oldt) {
        //不為空，例項不是自己是呼叫
if (otherHsv != null && otherHsv != this) {
            otherHsv.scrollTo(l, t);
        }

    }

    public void setOtherHsv(MyHorizontalScrollView otherHsv) {
        this
 
.otherHsv = otherHsv;
    }
2.MyActivity的程式碼

public class MyActivity extends AppCompatActivity {
    MyHorizontalScrollView scrollView1, scrollView2;

    @RequiresApi(api = Build.VERSION_CODES.M)
    @Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second
 
);
        scrollView1 = (MyHorizontalScrollView) findViewById(R.id.hsv1);
        scrollView2 = (MyHorizontalScrollView) findViewById(R.id.hsv2);
        scrollView1.setOtherHsv(scrollView2);
        scrollView2.setOtherHsv(scrollView1);

    }
}

圖片以後加吧！
