Question

我想禁用子viewpager的刷卡。

我目前使用此自定义子viewpager

public class CustomViewPager extends ViewPager {

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

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

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
    // Never allow swiping to switch between pages
    return true;
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    // Never allow swiping to switch between pages
    return true;
}

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {

    return true;
}
}

禁用子viewpager的滑动，但在该部分禁用父viewpager滑动。

Answer 1

要在不影响父事件的情况下禁用ViewPager滚动，请覆盖canScrollHorizontally（）方法：

@Override
    public boolean canScrollHorizontally(int direction) {
        //Disable horizontal scrolling
        if (enabled) {
            return super.canScrollHorizontally(direction);
        } else {
            return false;
        }
    }

Answer 2

您应该从子ViewPager中的onInterceptTouchEvent和onTouchEvent返回false。从onTouchEvent返回True将告诉父级视图已成功处理事件，这不是您想要的。

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
    // Never allow swiping to switch between pages
    return false;
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    // Never allow swiping to switch between pages
    return false;
}

在父viewPager中禁用子viewPager滑动
