是否有可能禁用对ViewPager滚动 [英] Is it possible to disable scrolling on a ViewPager

问题描述

我有一个 ViewPager 它实例化一个查看。我想禁止viewpager的两个滚动和子按钮短暂而搜索结果返回给图。我叫 viewPager.setEnabled（假）但这并不禁用它。

I have a ViewPager which instantiates a View. I'd like to disable both the scrolling of the viewpager and the child buttons momentarily while a search result is returned to the view. I've calling viewPager.setEnabled(false) but this doesn't disable it.

任何人有什么想法？

推荐答案

一个简单的解决方案是创建你自己的 ViewPager 的子类，有一个私人布尔标记， isPagingEnabled 。然后重写的onTouchEvent 和 onInterceptTouchEvent 的方法。如果 isPagingEnabled 等于true调用超方法，否则返回

A simple solution is to create your own subclass of ViewPager that has a private boolean flag, isPagingEnabled. Then override the onTouchEvent and onInterceptTouchEvent methods. If isPagingEnabled equals true invoke the super method, otherwise return.

public class CustomViewPager extends ViewPager {

    private boolean isPagingEnabled = true;

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

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

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

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

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

然后在你的 Layout.XML 文件替换任何＆LT; com.android.support.V4.ViewPager＆GT; 标签与＆LT; com.yourpackage.CustomViewPager＆GT; 标签

Then in your Layout.XML file replace any <com.android.support.V4.ViewPager> tags with <com.yourpackage.CustomViewPager> tags.
