ExpandableListView 中的 ViewPager 单击侦听器不起作用

Question

我的 ExpandableListView 中有一个自定义 ViewPager，点击监听器没有触发，有什么想法吗？我知道我可以在适配器中添加点击侦听器，但我不想这样做。

自定义寻呼机

public class CustomPager extends ViewPager {


/**
 * the last x position
 */
private float lastX;

/**
 * if the first swipe was from left to right (->), dont listen to swipes from the right
 */
private boolean slidingLeft;

/**
 * if the first swipe was from right to left (<-), dont listen to swipes from the left
 */
private boolean slidingRight;

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

public CustomPager(final Context context) {
    super(context);
}

@Override
public boolean onTouchEvent(final MotionEvent ev) {
    final int action = ev.getAction();
    switch (action) {
        case MotionEvent.ACTION_DOWN:

            // Disallow parent ViewPager to intercept touch events.
            this.getParent().requestDisallowInterceptTouchEvent(true);

            // save the current x position
            this.lastX = ev.getX();

            break;

        case MotionEvent.ACTION_UP:
            // Allow parent ViewPager to intercept touch events.
            this.getParent().requestDisallowInterceptTouchEvent(false);

            // save the current x position
            this.lastX = ev.getX();

            // reset swipe actions
            this.slidingLeft = false;
            this.slidingRight = false;

            break;

        case MotionEvent.ACTION_MOVE:
            /*
             * if this is the first standing_item, scrolling from left to
             * right should navigate in the surrounding ViewPager
             */
            if (this.getCurrentItem() == 0) {
                // swiping from left to right (->)?
                if (this.lastX <= ev.getX() && !this.slidingRight) {
                    // make the parent touch interception active -> parent pager can swipe
                    this.getParent().requestDisallowInterceptTouchEvent(false);
                } else {
                    /*
                     * if the first swipe was from right to left, dont listen to swipes
                     * from left to right. this fixes glitches where the user first swipes
                     * right, then left and the scrolling state gets reset
                     */
                    this.slidingRight = true;

                    // save the current x position
                    this.lastX = ev.getX();
                    this.getParent().requestDisallowInterceptTouchEvent(true);
                }
            } else
            /*
             * if this is the last standing_item, scrolling from right to
             * left should navigate in the surrounding ViewPager
             */
                if (this.getCurrentItem() == this.getAdapter().getCount() - 1) {
                    // swiping from right to left (<-)?
                    if (this.lastX >= ev.getX() && !this.slidingLeft) {
                        // make the parent touch interception active -> parent pager can swipe
                        this.getParent().requestDisallowInterceptTouchEvent(true);
                    } else {
                    /*
                     * if the first swipe was from left to right, dont listen to swipes
                     * from right to left. this fixes glitches where the user first swipes
                     * left, then right and the scrolling state gets reset
                     */
                        this.slidingLeft = true;

                        // save the current x position
                        this.lastX = ev.getX();
                        this.getParent().requestDisallowInterceptTouchEvent(true);
                    }
                }

            break;
    }

    super.onTouchEvent(ev);
    return true;
}


@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);

    int height = 0;
    for(int i = 0; i < getChildCount(); i++)
    {
        View child = getChildAt(i);
        child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
        int h = child.getMeasuredHeight();
        if(h > height) height = h;
    }

    heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY);

    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}

}

在我的适配器内充气

        if (groupPosition == 0) {
        final HeaderHolder viewHolder;
        convertView = mInflater.inflate(R.layout.season_team_fixtures_item, null);
        viewHolder = new HeaderHolder();
        viewHolder.customIndicator = (CircleIndicator) convertView.findViewById(R.id.indicator_custom);
        viewHolder.viewPager = (CustomPager) convertView.findViewById(R.id.pager);
        viewHolder.seeAll = (TextView) convertView.findViewById(R.id.AllFixtures);
        viewHolder.viewPager.setAdapter(adapter);
        viewHolder.customIndicator.setViewPager(itemView.viewPager);

在父 FrameLayout 中使用 android:descendantFocusability="blocksDescendants" 而不是线性布局
