问题描述

我正在尝试做什么:我正在尝试在程序运行时以编程方式启用/禁用在寻呼机中滑动

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

例如: 在流程中，如果我检查条件并且如果它返回 true 启用刷卡，并且如果条件返回 false 禁用滑动.

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;
} }

然后选择这个而不是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" />

您只需调用setPagingEnabled"方法，设置为false"，用​​户将无法滑动分页.

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

上述方法的问题: 我无法在流上设置属性，我:e .... 我可以启用刷卡或禁用刷卡.但我不能根据条件这样做

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. 我可以通过其他方式实现我的目标吗?如果可以，那是什么?
2. 或者这不可能吗?

推荐答案

以编程方式禁用滑动-

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

并使用它来手动滑动

touchView.setCurrentItem(int index);
