我使用此存储库https://github.com/dlukashev/AndroidSlidingUpPanel-foursquare-map-demo制作了滑动面板

但是，它包含一个在任何地方都没有涵盖的错误。

当我触摸任何地方以展开面板（listview）时效果很好，但是当我试图通过按住列表视图的顶部（screen2上的蓝线）来扩展它时，面板隐藏在地图下（framelayout）（screen3）

mapfragment 和 listview 的其余部分下的这个蓝线隐藏面板怎么可能很好地扩展它？

任何想法为什么？请给我一个提示如何解决它？

您需要覆盖 ListView

public class LockableListView extends ListView {

private boolean mScrollable = true;

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

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

public LockableListView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
}

public void setScrollingEnabled(boolean enabled) {
    mScrollable = enabled;
}

@Override
public boolean onTouchEvent(MotionEvent ev) {
    switch (ev.getAction()) {
        case MotionEvent.ACTION_DOWN:
            // if we can scroll pass the event to the superclass
            if (mScrollable) {
                return super.onTouchEvent(ev);
            }
            // only continue to handle the touch event if scrolling enabled
            return mScrollable; // mScrollable is always false at this point
        default:
            return super.onTouchEvent(ev);
    }
}

@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
    // Don't do anything with intercepted touch events if
    // we are not scrollable
    if (!mScrollable) {
        return false;
    } else {
        return super.onInterceptTouchEvent(ev);
    }
}

}

然后在需要时禁用滚动

private void collapseMap() {
    mSpaceView.setVisibility(View.VISIBLE);
    mTransparentView.setVisibility(View.GONE);
    if (mMap != null && mLocation != null) {
        mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(mLocation, 11f), 1000, null);
    }
    mListView.setScrollingEnabled(true);
}

private void expandMap() {
    mSpaceView.setVisibility(View.GONE);
    mTransparentView.setVisibility(View.INVISIBLE);
    if (mMap != null) {
        mMap.animateCamera(CameraUpdateFactory.zoomTo(14f), 1000, null);
    }
    mListView.setScrollingEnabled(false);
}

我将此更改推送到 GitHub https://github.com/dlukashev/AndroidSlidingUpPanel-foursquare-map-demo/commit/7b869394e9d197e6f56a833804426577dcb8458a
