是否可以禁用 ViewPager 上的滚动 [英] Is it possible to disable scrolling on a ViewPager

问题描述

我有一个 ViewPager 实例化一个 View.我想在搜索结果返回到视图时暂时禁用 viewpager 和子按钮的滚动.我调用了 viewPager.setEnabled(false) 但这并没有禁用它.

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.

有人有什么想法吗?

一个简单的解决方案是创建您自己的 ViewPager 子类，它有一个 private boolean 标志，<代码>isPagingEnabled.然后覆盖 onTouchEvent 和 onInterceptTouchEvent 方法.如果 isPagingEnabled 等于 true，则调用 super 方法，否则 return.

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;
    }
}

然后在您的 Layout.XML 文件中将任何 标签替换为 ; 标签.

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