我试图禁止ViewPager在选项卡之间滚动。我有以下情况:

        public class MyClass extends ViewPager implements ViewPager.OnPageChangeListener, OnTouchListener {

             public MyClass() {
               setOnTouchListener(this);
             }

@Override
    public void onPageScrollStateChanged(int state) {
        Log.d("Testing", TAG + " onPageScrollStateChanged");
    }

    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
        Log.d("Testing", TAG + " onPageScrolled");
    }

    @Override
    public void onPageSelected(int position) {
        Log.d("Testing", TAG + " onPageSelected");
    }

        @Override
        public boolean onInterceptTouchEvent(MotionEvent event) {
            Log.d("Testing", "intercept");
                return false;
        }

            @Override
            public boolean onTouch(View v, MotionEvent event) {
                Log.d("Testing", "touch2");
                    return false;
            }

        }

我通常具有onPageScrolled和onPageScrollStateChanged的日志,但没有onInterceptTouchEvent和onTouch的日志。我究竟做错了什么?

最佳答案

这就是我(整个类(class))的处理方式:

public class SelectiveViewPager extends ViewPager {
private boolean paging = true;

public SelectiveViewPager(Context context) {
    super(context);
}

public SelectiveViewPager(Context context, AttributeSet attributeSet){
    super(context, attributeSet);
}

@Override
public boolean onInterceptTouchEvent(MotionEvent e) {
    if (paging) {
        return super.onInterceptTouchEvent(e);
    }

    return false;
}

public void setPaging(boolean p){ paging = p; }

}

bool paging为您提供了根据需要打开和关闭此选项的选项。如果不需要,只需return false。如果您没有在onTouch中做任何特别的事情,则无需覆盖它。
