我有一个新的MapFragments ScrollView.实际上它是一个SupportMapFragment,但无论如何.它有效,但有两个问题:
滚动时,会留下黑色面具.黑色完全覆盖了地图所在的区域,除了+/-缩放按钮所在的孔.见下面的截图.这是在Android 4.0上.
requestDisallowInterceptTouchEvent()当用户与地图交互以防止ScrollView拦截触摸时,视图不会使用,因此如果您尝试在地图中垂直平移,则只会滚动包含ScrollView.理论上我可以派生一个视图类MapView并添加该功能,但是如何才能MapFragment使用我的自定义MapView而不是标准的?

在mapview片段上应用透明图像似乎可以解决问题.这不是最漂亮的,但似乎有效.这是一个显示以下内容的XML代码段:
<RelativeLayout
android:id="@+id/relativeLayout1"
android:layout_width="match_parent"
android:layout_height="300dp" >
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
<ImageView
android:id="@+id/imageView123"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@drawable/temp_transparent" />
</RelativeLayout>

对我来说,添加透明的ImageView并没有帮助完全删除黑色面具.滚动时,地图的顶部和底部部分仍显示黑色蒙版.
所以对于它的解决方案,我在这个答案中发现了一个小小的变化.我补充说,
android:layout_marginTop="-100dp"
android:layout_marginBottom="-100dp"

到我的地图片段,因为它是垂直scrollview.所以我的布局现在看起来像这样:
<RelativeLayout
android:id="@+id/map_layout"
android:layout_width="match_parent"
android:layout_height="300dp">
<fragment
android:id="@+id/mapview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="-100dp"
android:layout_marginBottom="-100dp"
android:name="com.google.android.gms.maps.MapFragment"/>
<ImageView
android:id="@+id/transparent_image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@color/transparent" />
</RelativeLayout>

要解决requestDisallowInterceptTouchEvent(true)我为主ScrollView 设置的问题的第二部分.当用户触摸透明图像并移动时,我禁用了透明图像上的触摸MotionEvent.ACTION_DOWN,MotionEvent.ACTION_MOVE以便地图片段可以进行触摸事件.
ScrollView mainScrollView = (ScrollView) findViewById(R.id.main_scrollview);
ImageView transparentImageView = (ImageView) findViewById(R.id.transparent_image);
transparentImageView.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
int action = event.getAction();
switch (action) {
case MotionEvent.ACTION_DOWN:
// Disallow ScrollView to intercept touch events.
mainScrollView.requestDisallowInterceptTouchEvent(true);
// Disable touch on transparent view
return false;
case MotionEvent.ACTION_UP:
// Allow ScrollView to intercept touch events.
mainScrollView.requestDisallowInterceptTouchEvent(false);
return true;
case MotionEvent.ACTION_MOVE:
mainScrollView.requestDisallowInterceptTouchEvent(true);
return false;
default:
return true;
}
}
});

这对我有用.希望它可以帮助你..
经过大量研发后完成:
fragment_one.xml应该如下所示:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/scrollViewParent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="400dip" >
<com.google.android.gms.maps.MapView
android:id="@+id/mapView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<View
android:id="@+id/customView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@android:color/transparent" />
</RelativeLayout>
<!-- Your other elements are here -->
</LinearLayout>
</ScrollView>

您的FragmentOne.java Java类如下所示:

private MapView mapView;
private UiSettings mUiSettings;
private View customView
