如何在Android中禁用或启用ViewPager刷卡 [英] How to disable or enable viewpager swiping in android

问题描述

我要执行的操作:我正在尝试通过程序运行时以编程方式启用/禁用在寻呼机中刷卡

What i am trying to do: I am trying to Enable/disable swiping in pager programatically when the program is running

Ex: 在流程中，如果我检查条件并返回true则启用刷卡，如果条件返回false则禁用刷卡./p>

---

我正在使用的解决方案就是这个

Ex: When on the flow if i check for a condition and if it returns true enable swiping, and if condition returns false disable swiping.

public class CustomViewPager extends ViewPager {

private boolean enabled;

public CustomViewPager(Context context, AttributeSet attrs) {
    super(context, attrs);
    this.enabled = true;
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    if (this.enabled) {
        return super.onTouchEvent(event);
    }

    return false;
}

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
    if (this.enabled) {
        return super.onInterceptTouchEvent(event);
    }

    return false;
}

public void setPagingEnabled(boolean enabled) {
    this.enabled = enabled;
} }

然后选择它而不是XML中的内置viewpager

Then select this instead of the builtin viewpager in XML

<mypackage.CustomViewPager 
android:id="@+id/myViewPager" 
android:layout_height="match_parent" 
android:layout_width="match_parent" />

您只需要使用"false"调用"setPagingEnabled"方法，用户将无法滑动以进行分页.

You just need to call the "setPagingEnabled" method with "false" and users won't be able to swipe to paginate.

上述方法存在的问题:我无法在流上设置属性，即....我可以启用刷卡功能或禁用刷卡功能.但是我不能根据条件做到这一点

Problem with above methodology: i cannot set the property on the flow, I:e .... I either can enable swiping or disable swiping. But i cannot do this based on condition

1. 我能以其他方式实现我的目标吗?
2. 或者这不可能吗?

推荐答案

通过-

    final View touchView = findViewById(R.id.Pager); 
    touchView.setOnTouchListener(new View.OnTouchListener() 
    {         
        @Override
        public boolean onTouch(View v, MotionEvent event)
        { 
           return true; 
        }
     });

并使用它手动滑动

touchView.setCurrentItem(int index);
