我希望在 ScrollView 中有一个 MapView,但是当我尝试滚动地图时,ScrollView 优先!有没有办法在地图内滚动时优先考虑 MapView,否则优先考虑 ScrollView?
谢谢!
我已经遇到同样的问题10天了,但几分钟前我得到了解决方案! 这是解决方案。 我制作了一个自定义 MapView 并像这样重写 onTouchEvent() 。
@Override
public boolean onTouchEvent(MotionEvent ev) {
int action = ev.getAction();
switch (action) {
case MotionEvent.ACTION_DOWN:
// Disallow ScrollView to intercept touch events.
this.getParent().requestDisallowInterceptTouchEvent(true);
break;
case MotionEvent.ACTION_UP:
// Allow ScrollView to intercept touch events.
this.getParent().requestDisallowInterceptTouchEvent(false);
break;
}
// Handle MapView's touch events.
super.onTouchEvent(ev);
return true;
}
一种更好/更简单的方法来做到这一点,无需操纵单独的触摸事件。 如果您使用 MapView,这将起作用:
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
/**
* Request all parents to relinquish the touch events
*/
getParent().requestDisallowInterceptTouchEvent(true);
return super.dispatchTouchEvent(ev);
}
全班:
public class CustomMapView extends MapView {
public CustomMapView(Context context) {
super(context);
}
public CustomMapView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomMapView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public CustomMapView(Context context, GoogleMapOptions options) {
super(context, options);
}
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
/**
* Request all parents to relinquish the touch events
*/
getParent().requestDisallowInterceptTouchEvent(true);
return super.dispatchTouchEvent(ev);
}
}
如果您使用的是 MapFragment,那么您可以将片段放入自定义视图中,然后在
dispatchTouchEvent()
中进行 requestDisallowInterceptTouchEvent
调用。
制作你自己的地图并使用它。它完全适合我。
public class CustomMapView extends MapView {
public CustomMapView(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
switch (ev.getAction()) {
case MotionEvent.ACTION_UP:
System.out.println("unlocked");
this.getParent().requestDisallowInterceptTouchEvent(false);
break;
case MotionEvent.ACTION_DOWN:
System.out.println("locked");
this.getParent().requestDisallowInterceptTouchEvent(true);
break;
}
return super.dispatchTouchEvent(ev);
}}
在布局 xml 中,
<com.yourpackage.xxxx.utils.CustomMapView
android:id="@+id/customMap"
android:layout_width="match_parent"
android:layout_height="400dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
/>
对于那些想要完整工作代码的人。在这里
自定义地图视图类
public class CustomMapView extends MapView {
private ViewParent mViewParent;
public CustomMapView(Context context) {
super(context);
}
public CustomMapView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomMapView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public CustomMapView(Context context, GoogleMapOptions options) {
super(context, options);
}
public void setViewParent(@Nullable final ViewParent viewParent) { //any ViewGroup
mViewParent = viewParent;
}
@Override
public boolean onInterceptTouchEvent(final MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
if (null == mViewParent) {
getParent().requestDisallowInterceptTouchEvent(true);
} else {
mViewParent.requestDisallowInterceptTouchEvent(true);
}
break;
case MotionEvent.ACTION_UP:
if (null == mViewParent) {
getParent().requestDisallowInterceptTouchEvent(false);
} else {
mViewParent.requestDisallowInterceptTouchEvent(false);
}
break;
default:
break;
}
return super.onInterceptTouchEvent(event);
}
}
活动布局xml
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<location.to.your.CustomMapView
android:id="@+id/mapView"
android:layout_width="match_parent"
android:layout_height="250dp"
/>
</ScrollView>
在您的 Activity 或片段中实例化自定义地图类
CustomMapView mapView = (CustomMapView) findViewById(R.id.mapView);
就这样享受吧
您可以像这样创建自定义 MapView:
public class CustomMapView extends MapView {
private MapFragment.ControlLock mCallbackControl;
public CustomMapView(Context context) {
this(context, null);
}
public CustomMapView(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}
public CustomMapView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public CustomMapView(Context context, GoogleMapOptions options) {
super(context, options);
}
public void setCallback(MapFragment.ControlLock callbackControl) {
this.mCallbackControl = callbackControl;
}
@Override
public boolean dispatchTouchEvent(MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_UP:
System.out.println("unlocked");
mCallbackControl.unlock(); /* Interface */
break;
case MotionEvent.ACTION_DOWN:
System.out.println("locked");
mCallbackControl.lock(); /* Interface */
break;
}
return super.dispatchTouchEvent(event);
}
}
我尝试过重写 MapView.onTouchEvent(...),但它对我不起作用。 这是运行良好的代码(覆盖 MapView.onInterceptTouchEvent(...)):
public class MyMapView extends MapView {
private ViewParent mViewParent;
//add constructors here
public void setViewParent(@Nullable final ViewParent viewParent) { //any ViewGroup
mViewParent = viewParent;
}
@Override
public boolean onInterceptTouchEvent(final MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
if (null == mViewParent) {
getParent().requestDisallowInterceptTouchEvent(true);
} else {
mViewParent.requestDisallowInterceptTouchEvent(true);
}
break;
case MotionEvent.ACTION_UP:
if (null == mViewParent) {
getParent().requestDisallowInterceptTouchEvent(false);
} else {
mViewParent.requestDisallowInterceptTouchEvent(false);
}
break;
default:
break;
}
return super.onInterceptTouchEvent(event);
}
}
如果有人想要 kotlin 语言的课程。
我按照@rotem
的建议使用了
dispatchTouchEvent
class CustomMapView : MapView {
constructor(context: Context):
super(context)
constructor(context: Context, googleMapOptions: GoogleMapOptions):
super(context, googleMapOptions)
constructor(context: Context, attributeSet: AttributeSet):
super(context, attributeSet)
constructor(context: Context, attributeSet: AttributeSet, int: Int):
super(context, attributeSet, int)
override fun dispatchTouchEvent(event: MotionEvent?): Boolean {
Log.d("CustomWebView", "touchevent")
when(event?.action) {
MotionEvent.ACTION_UP -> {
Log.d("CustomWebView", "disallow Intercept")
parent.requestDisallowInterceptTouchEvent(false)
}
MotionEvent.ACTION_DOWN -> {
Log.d("CustomWebView", "allow Intercept")
parent.requestDisallowInterceptTouchEvent(true)
}
}
return super.dispatchTouchEvent(event)
}
}
您可以简单地将 MapView 放入布局本身并覆盖 onTouch 或设置 Click-Listener - 对我来说最简单的方法,因为我需要触摸 ScrollView 中的整个 MapView。
如果您在滚动视图中有地图视图,那么您必须向地图视图明确提及以下参数:
mMapView.setClickable(true);
mMapView.setFocusable(true);
mMapView.setDuplicateParentStateEnabled(false);
在 Kotlin 中扩展 Mapbox 的 MapView(同时遵循 @fupduck 的代码):
import android.content.Context
import android.util.AttributeSet
import android.util.Log
import android.view.MotionEvent
import com.mapbox.maps.MapInitOptions
import com.mapbox.maps.MapView
class CustomMapView : MapView {
constructor(context: Context):
super(context)
constructor(context: Context, googleMapOptions: MapInitOptions):
super(context, googleMapOptions)
constructor(context: Context, attributeSet: AttributeSet):
super(context, attributeSet)
constructor(context: Context, attributeSet: AttributeSet, int: Int):
super(context, attributeSet, int)
override fun dispatchTouchEvent(event: MotionEvent?): Boolean {
Log.d("CustomWebView", "touchevent")
when(event?.action) {
MotionEvent.ACTION_UP -> {
Log.d("CustomWebView", "disallow Intercept")
parent.requestDisallowInterceptTouchEvent(false)
}
MotionEvent.ACTION_DOWN -> {
Log.d("CustomWebView", "allow Intercept")
parent.requestDisallowInterceptTouchEvent(true)
}
}
return super.dispatchTouchEvent(event)
}
}
可以在 XML 中轻松使用:
<com.example.PackageName.CustomMapView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:mapbox="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/custom_map_view_route"
android:layout_width="match_parent"
android:layout_height="240dp"
mapbox:mapbox_cameraTargetLat="26"
mapbox:mapbox_cameraTargetLng="75"
mapbox:mapbox_cameraZoom="14.0" />
