在谷歌mapfragment细线滑动面板

本文介绍了在谷歌mapfragment细线滑动面板 - 向上滑动面板的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我使用这个库 https://github.com/dlukashev/AndroidSlidingUpPanel-四方 - 地图演示

但是,它包含未覆盖的任何地方一个bug被纠正。

在我接触的任何地方以扩大面板(列表视图)效果很好,但是当我试图按住地图(的FrameLayout)(画面3)在列表视图的顶部(在画面2蓝线)面板隐藏其展开

如何甚至有可能这个蓝色的线下mapfragment列表视图和其他部分隐藏面板展开呢?

任何想法,为什么?请给我只是一个提示如何解决?

请看屏幕:

解决方案

您需要覆盖的ListView

 公共类LockableListView扩展的ListView {

私人布尔mScrollable = TRUE;

公共LockableListView(上下文的背景下){
    超(上下文);
}

公共LockableListView(上下文的背景下,ATTRS的AttributeSet){
    超(背景下,ATTRS);
}

公共LockableListView(上下文的背景下,ATTRS的AttributeSet,诠释defStyle){
    超(背景下,ATTRS,defStyle);
}

公共无效setScrollingEnabled(布尔启用){
    mScrollable =启用;
}

@覆盖
公共布尔的onTouchEvent(MotionEvent EV){
    开关(ev.getAction()){
        案例MotionEvent.ACTION_DOWN:
            //如果我们可以滚动的事件传递给超
            如果(mScrollable){
                返回super.onTouchEvent(EV);
            }
            //只有不断地处理触摸事件,如果滚动启用
            返回mScrollable; // mScrollable永远是假的,在这一点上
        默认:
            返回super.onTouchEvent(EV);
    }
}

@覆盖
公共布尔onInterceptTouchEvent(MotionEvent EV){
    //不要拦截触摸事件,如果做任何事情
    //我们不滚动
    如果(!mScrollable){
        返回false;
    } 其他 {
        返回super.onInterceptTouchEvent(EV);
    }
}
 

}

然后把禁用滚动需要时

 私人无效collapseMap(){
    mSpaceView.setVisibility(View.VISIBLE);
    mTransparentView.setVisibility(View.GONE);
    如果(MMAP = NULL和放大器;!&安培;!mLocation = NULL){
        mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(mLocation,11F),1000,NULL);
    }
    mListView.setScrollingEnabled(真正的);
}

私人无效expandMap(){
    mSpaceView.setVisibility(View.GONE);
    mTransparentView.setVisibility(View.INVISIBLE);
    如果(MMAP!= NULL){
        mMap.animateCamera(CameraUpdateFactory.zoomTo(14F),1000,NULL);
    }
    mListView.setScrollingEnabled(假);
}
 

我把这个变成GitHub的https://github.com/dlukashev/AndroidSlidingUpPanel-foursquare-map-demo/commit/7b869394e9d197e6f56a833804426577dcb8458a

I made slidinguppanel using this repository https://github.com/dlukashev/AndroidSlidingUpPanel-foursquare-map-demo

However, it contains one bug which is not covered anywhere.

When I touch anywhere to expand panel (listview) works well, but while I'm trying to expand it by holding a top of a list view (blue line on screen2) panel hide under the map (framelayout) (screen3)

How it's even possible that this blue line hiding panel under mapfragment and rest of listview expand it well?

Any ideas why? Please give me just a hint how to fix it?

Please look at the screen:

解决方案

You need to override 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);
    }
}

}

Then put disable scrolling when needed

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);
}
