我有一个NestedScrollView
作为父级,Fragment包含googleMap
作为其子级。当我在地图中向下或向上滚动时,NesetdScrollView会滚动,我无法在地图内滚动。直到现在我已经通过创建透明图像尝试了堆栈溢出的解决方案,但它对我没用。
XML:
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/car_progress"
android:id="@+id/nested_scroll"
android:visibility="gone"

............
............
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@id/first_section"
android:visibility="gone"
android:id="@+id/map_wrapper"
android:orientation="vertical"
android:layout_marginTop="10dp"

<fragment xmlns:android="http://schemas.android.com/apk/res/android"

<ImageView

android:layout_height="wrap_content"
android:id="@+id/imagetrans"

android:layout_alignLeft="@+id/map"
android:layout_alignStart="@+id/map"
android:src="@android:color/transparent"/>
</RelativeLayout>
.....

</android.support.v4.widget.NestedScrollView>
代码:
transImg.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.
nv.requestDisallowInterceptTouchEvent(true);
// Disable touch on transparent view
return false;
case MotionEvent.ACTION_UP:
// Allow ScrollView to intercept touch events.
nv.requestDisallowInterceptTouchEvent(false);
return true;
case MotionEvent.ACTION_MOVE:
nv.requestDisallowInterceptTouchEvent(true);
return false;
default:
return true;
}
}
});

试试这个...使用带有可触摸包装的自定义地图片段。
MySupportMapFragment mSupportMapFragment;
mSupportMapFragment = (MySupportMapFragment) getChildFragmentManager().findFragmentById(R.id.googleMap);
if(mSupportMapFragment != null)
mSupportMapFragment.setListener(new MySupportMapFragment.OnTouchListener() {
@Override
public void onTouch() {
scrollView.requestDisallowInterceptTouchEvent(true);
}
});
MySupportMapFragment
public class MySupportMapFragment extends SupportMapFragment {
private OnTouchListener mListener;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState) {
View layout = super.onCreateView(inflater, parent, savedInstanceState);
TouchableWrapper frameLayout = new TouchableWrapper(getActivity());
frameLayout.setBackgroundColor(getResources().getColor(android.R.color.transparent));
((ViewGroup) layout).addView(frameLayout,
new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
return layout;
}
public void setListener(OnTouchListener listener) {
mListener = listener;
}
public interface OnTouchListener {
public abstract void onTouch();
}
public class TouchableWrapper extends FrameLayout {
public TouchableWrapper(Context context) {
super(context);
}
@Override
public boolean dispatchTouchEvent(MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
mListener.onTouch();
break;
case MotionEvent.ACTION_UP:
mListener.onTouch();
break;
}
return super.dispatchTouchEvent(event);
}
}
}
