我正在尝试使用新的Google Maps API v2，在单击标记后制作自定义InfoWindow。 我想让它看起来像Google原始地图应用程序中的样子。 就像这样：
ImageButton内部时，它不起作用 - 整个InfoWindow被选中，而不仅仅是ImageButton。 我读到这是因为没有View本身，而只有快照，所以无法将单个项目区分开来。package com.circlegate.tt.cg.an.lib.map;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.model.Marker;
import android.content.Context;
import android.graphics.Point;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.View;
import android.widget.RelativeLayout;
public class MapWrapperLayout extends RelativeLayout {
/**
* Reference to a GoogleMap object
*/
private GoogleMap map;
/**
* Vertical offset in pixels between the bottom edge of our InfoWindow
* and the marker position (by default it's bottom edge too).
* It's a good idea to use custom markers and also the InfoWindow frame,
* because we probably can't rely on the sizes of the default marker and frame.
*/
private int bottomOffsetPixels;
/**
* A currently selected marker
*/
private Marker marker;
/**
* Our custom view which is returned from either the InfoWindowAdapter.getInfoContents
* or InfoWindowAdapter.getInfoWindow
*/
private View infoWindow;
public MapWrapperLayout(Context context) {
super(context);
}
public MapWrapperLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public MapWrapperLayout(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
/**
* Must be called before we can route the touch events
*/
public void init(GoogleMap map, int bottomOffsetPixels) {
this.map = map;
this.bottomOffsetPixels = bottomOffsetPixels;
}
/**
* Best to be called from either the InfoWindowAdapter.getInfoContents
* or InfoWindowAdapter.getInfoWindow.
*/
public void setMarkerWithInfoWindow(Marker marker, View infoWindow) {
this.marker = marker;
this.infoWindow = infoWindow;
}
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
boolean ret = false;
// Make sure that the infoWindow is shown and we have all the needed references
if (marker != null && marker.isInfoWindowShown() && map != null && infoWindow != null) {
// Get a marker position on the screen
Point point = map.getProjection().toScreenLocation(marker.getPosition());
// Make a copy of the MotionEvent and adjust it's location
// so it is relative to the infoWindow left top corner
MotionEvent copyEv = MotionEvent.obtain(ev);
copyEv.offsetLocation(
-point.x + (infoWindow.getWidth() / 2),
-point.y + infoWindow.getHeight() + bottomOffsetPixels);
// Dispatch the adjusted MotionEvent to the infoWindow
ret = infoWindow.dispatchTouchEvent(copyEv);
}
// If the infoWindow consumed the touch event, then just return true.
// Otherwise pass this event to the super class and return it's result
return ret || super.dispatchTouchEvent(ev);
}
}
所有这些都将使InfoView内部的视图“活”起来 - OnClickListeners将开始触发等。
第二部分： 剩下的问题是，显然，您无法在屏幕上看到InfoWindow的任何UI更改。要做到这一点，您必须手动调用Marker.showInfoWindow。现在，如果您对InfoWindow进行了某些永久更改（例如将按钮标签更改为其他内容），那么这就足够了。
但是，显示按下状态的按钮或类似的东西更加复杂。首先的问题是，我至少无法使InfoWindow显示普通按钮的按下状态。即使我长时间按下按钮，它也仍然未被按下。我相信这是地图框架本身处理的内容，它可能确保不在信息窗口中显示任何瞬态状态。但我可能是错的，我没有尝试找出这个问题。
我所做的是另一种恶心的黑客方式-我将一个OnTouchListener附加到按钮上，并在按钮被按下或释放时手动切换其背景到两个自定义可绘制对象-一个处于正常状态的按钮和另一个处于按下状态的按钮。这不是很好，但有效：）。现在，我能够看到按钮在屏幕上在正常状态和按下状态之间切换。
仍然有一个小问题-如果您过快地单击按钮，它不会显示按下状态-它仅保持在正常状态（尽管单击本身已被触发，因此按钮“有效”）。至少这是在我的Galaxy Nexus上的情况。所以我最后做的一件事是稍微延迟了按钮的按下状态。这也相当丑陋，我不确定它在一些旧设备上是否有效，但我怀疑即使地图框架本身也会这样做。您可以自己尝试-当您单击整个InfoWindow时，它会保持在按下状态较长时间，然后再变回正常状态的按钮（同样-至少在我的手机上）。这实际上是在原始的Google Maps应用程序上运行的方式。
无论如何，我写了一个自定义类来处理按钮状态更改和我提到的所有其他事情，所以这里是代码：
package com.circlegate.tt.cg.an.lib.map;
import android.graphics.drawable.Drawable;
import android.os.Handler;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import com.google.android.gms.maps.model.Marker;
public abstract class OnInfoWindowElemTouchListener implements OnTouchListener {
private final View view;
private final Drawable bgDrawableNormal;
private final Drawable bgDrawablePressed;
private final Handler handler = new Handler();
private Marker marker;
private boolean pressed = false;
public OnInfoWindowElemTouchListener(View view, Drawable bgDrawableNormal, Drawable bgDrawablePressed) {
this.view = view;
this.bgDrawableNormal = bgDrawableNormal;
this.bgDrawablePressed = bgDrawablePressed;
}
public void setMarker(Marker marker) {
this.marker = marker;
}
@Override
public boolean onTouch(View vv, MotionEvent event) {
if (0 <= event.getX() && event.getX() <= view.getWidth() &&
0 <= event.getY() && event.getY() <= view.getHeight())
{
switch (event.getActionMasked()) {
case MotionEvent.ACTION_DOWN: startPress(); break;
// We need to delay releasing of the view a little so it shows the pressed state on the screen
case MotionEvent.ACTION_UP: handler.postDelayed(confirmClickRunnable, 150); break;
case MotionEvent.ACTION_CANCEL: endPress(); break;
default: break;
}
}
else {
// If the touch goes outside of the view's area
// (like when moving finger out of the pressed button)
// just release the press
endPress();
}
return false;
}
private void startPress() {
if (!pressed) {
pressed = true;
handler.removeCallbacks(confirmClickRunnable);
view.setBackground(bgDrawablePressed);
if (marker != null)
marker.showInfoWindow();
}
}
private boolean endPress() {
if (pressed) {
this.pressed = false;
handler.removeCallbacks(confirmClickRunnable);
view.setBackground(bgDrawableNormal);
if (marker != null)
marker.showInfoWindow();
return true;
}
else
return false;
}
private final Runnable confirmClickRunnable = new Runnable() {
public void run() {
if (endPress()) {
onClickConfirmed(view, marker);
}
}
};
/**
* This is called after a successful click
*/
protected abstract void onClickConfirmed(View v, Marker marker);
}
这是我使用的自定义信息窗口布局文件：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_vertical" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_marginRight="10dp" >
<TextView
android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="18sp"
android:text="Title" />
<TextView
android:id="@+id/snippet"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="snippet" />
</LinearLayout>
<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
</LinearLayout>
测试活动布局文件（MapFragment位于MapWrapperLayout内）：
<com.circlegate.tt.cg.an.lib.map.MapWrapperLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/map_relative_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.MapFragment" />
</com.circlegate.tt.cg.an.lib.map.MapWrapperLayout>
最后是一个测试活动的源代码，它将所有这些内容粘合在一起：
package com.circlegate.testapp;

public class MainActivity extends Activity {
private ViewGroup infoWindow;

private OnInfoWindowElemTouchListener infoButtonListener;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final MapFragment mapFragment = (MapFragment)getFragmentManager().findFragmentById(R.id.map);
final MapWrapperLayout mapWrapperLayout = (MapWrapperLayout)findViewById(R.id.map_relative_layout);
final GoogleMap map = mapFragment.getMap();
// MapWrapperLayout initialization
// 39 - default marker height
// 20 - offset between the default InfoWindow bottom edge and it's content bottom edge
mapWrapperLayout.init(map, getPixelsFromDp(this, 39 + 20));
// We want to reuse the info window for all the markers,
// so let's create only one class member instance
this.infoWindow = (ViewGroup)getLayoutInflater().inflate(R.layout.info_window, null);
this.infoTitle = (TextView)infoWindow.findViewById(R.id.title);
this.infoSnippet = (TextView)infoWindow.findViewById(R.id.snippet);
this.infoButton = (Button)infoWindow.findViewById(R.id.button);
// Setting custom OnTouchListener which deals with the pressed state
// so it shows up
this.infoButtonListener = new OnInfoWindowElemTouchListener(infoButton,
getResources().getDrawable(R.drawable.btn_default_normal_holo_light),
getResources().getDrawable(R.drawable.btn_default_pressed_holo_light))
{
@Override
protected void onClickConfirmed(View v, Marker marker) {
// Here we can perform some action triggered after clicking the button
Toast.makeText(MainActivity.this, marker.getTitle() + "'s button clicked!", Toast.LENGTH_SHORT).show();
}
};
this.infoButton.setOnTouchListener(infoButtonListener);
map.setInfoWindowAdapter(new InfoWindowAdapter() {
@Override
public View getInfoWindow(Marker marker) {
return null;
}
@Override
public View getInfoContents(Marker marker) {
// Setting up the infoWindow with current's marker info
infoTitle.setText(marker.getTitle());
infoSnippet.setText(marker.getSnippet());
infoButtonListener.setMarker(marker);
// We must call this to set the current marker and infoWindow references
// to the MapWrapperLayout
mapWrapperLayout.setMarkerWithInfoWindow(marker, infoWindow);
return infoWindow;
}
});
// Let's add a couple of markers
map.addMarker(new MarkerOptions()
.title("Prague")
.snippet("Czech Republic")
.position(new LatLng(50.08, 14.43)));
map.addMarker(new MarkerOptions()
.title("Paris")
.snippet("France")
.position(new LatLng(48.86,2.33)));
map.addMarker(new MarkerOptions()
.title("London")
.snippet("United Kingdom")
.position(new LatLng(51.51,-0.1)));
}
public static int getPixelsFromDp(Context context, float dp) {
final float scale = context.getResources().getDisplayMetrics().density;
return (int)(dp * scale + 0.5f);
}
}
view.setBackground(bgDrawablePressed);替换为以下代码才能在Android Gingerbread中运行：if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {
view.setBackgroundDrawable(bgDrawablePressed);
} else {
view.setBackground(bgDrawablePressed);
}请注意，代码中还有一个view.setBackground需要进行相同的更改。 - Balaji对于那些无法运行choose007的答案的人
如果chose007的解决方案中clickListener不能始终正常工作，请尝试使用View.onTouchListener来代替clickListener。使用任何一个动作ACTION_UP或ACTION_DOWN处理触摸事件。由于某种原因，地图上的infoWindow在分派给clickListeners时会导致一些奇怪的行为。
infoWindow.findViewById(R.id.my_view).setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
int action = MotionEventCompat.getActionMasked(event);
switch (action){
case MotionEvent.ACTION_UP:
Log.d(TAG,"a view in info window clicked" );
break;
}
return true;
}
编辑：以下是我逐步完成的过程
首先在您的活动/片段中的某个位置扩充自己的信息窗口（全局变量）。我的在片段内。还要确保信息窗口布局中的根视图是LinearLayout（由于某种原因，RelativeLayout在信息窗口中占用了整个屏幕宽度）。
infoWindow = (ViewGroup) getActivity().getLayoutInflater().inflate(R.layout.info_window, null);
/* Other global variables used in below code*/
private HashMap<Marker,YourData> mMarkerYourDataHashMap = new HashMap<>();
private GoogleMap mMap;
private MapWrapperLayout mapWrapperLayout;
接下来，在 Google Maps Android API 的 onMapReady 回调函数中（如果您不知道 onMapReady 是什么，请参考此链接：Maps > Documentation - Getting Started）。
@Override
public void onMapReady(GoogleMap googleMap) {
/*mMap is global GoogleMap variable in activity/fragment*/
mMap = googleMap;
/*Some function to set map UI settings*/
setYourMapSettings();
MapWrapperLayout 初始化

interactive-infowindow-like-in-original-android-go/15040761#15040761
39 - 默认标记高度
20 - 默认信息窗口底部边缘与其内容底部边缘之间的偏移量
*/
mapWrapperLayout.init(mMap, Utils.getPixelsFromDp(mContext, 39 + 20));
/*handle marker clicks separately - not necessary*/
mMap.setOnMarkerClickListener(this);
mMap.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter() {
@Override
public View getInfoWindow(Marker marker) {
return null;
}
@Override
public View getInfoContents(Marker marker) {
YourData data = mMarkerYourDataHashMap.get(marker);
setInfoWindow(marker,data);
mapWrapperLayout.setMarkerWithInfoWindow(marker, infoWindow);
return infoWindow;
}
});
}
SetInfoWindow method
private void setInfoWindow (final Marker marker, YourData data)
throws NullPointerException{
if (data.getVehicleNumber()!=null) {
((TextView) infoWindow.findViewById(R.id.VehicelNo))
.setText(data.getDeviceId().toString());
}
if (data.getSpeed()!=null) {
((TextView) infoWindow.findViewById(R.id.txtSpeed))
.setText(data.getSpeed());
}
//handle dispatched touch event for view click
infoWindow.findViewById(R.id.any_view).setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
int action = MotionEventCompat.getActionMasked(event);
switch (action) {
case MotionEvent.ACTION_UP:
Log.d(TAG,"any_view clicked" );
break;
}
return true;
}
});
单独处理标记点击事件
@Override
public boolean onMarkerClick(Marker marker) {
Log.d(TAG,"on Marker Click called");
marker.showInfoWindow();
CameraPosition cameraPosition = new CameraPosition.Builder()
.target(marker.getPosition()) // Sets the center of the map to Mountain View
.zoom(10)
.build();
mMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition),1000,null);
return true;
}
只是一种猜测，我没有足够的经验来尝试它... )-:
由于GoogleMap是片段，因此应该可以捕获标记onClick事件并显示自定义片段视图。地图片段仍将显示在背景上。有人尝试过吗？为什么不行？
缺点是地图片段将被冻结在背景上，直到自定义信息片段将控制权返回给它。
这非常简单。
googleMap.setInfoWindowAdapter(new InfoWindowAdapter() {
// Use default InfoWindow frame
@Override
public View getInfoWindow(Marker marker) {
return null;
}
// Defines the contents of the InfoWindow
@Override
public View getInfoContents(Marker marker) {
// Getting view from the layout file info_window_layout
View v = getLayoutInflater().inflate(R.layout.info_window_layout, null);
// Getting reference to the TextView to set title
TextView note = (TextView) v.findViewById(R.id.note);
note.setText(marker.getTitle() );
// Returning the view containing InfoWindow contents
return v;
}
});
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<TextView

希望这能有所帮助。我们可以在http://wptrafficanalyzer.in/blog/customizing-infowindow-contents-in-google-map-android-api-v2-using-infowindowadapter/#comment-39731找到自定义信息窗口的工作示例。
编辑：此代码显示了如何在infoWindow上添加自定义视图。该代码未处理自定义视图项上的点击事件。因此，它接近答案但不完全是答案，这就是为什么它没有被接受为答案的原因。
View.draw(Canvas)）...这意味着对视图进行的任何后续更改都不会反映在地图上的信息窗口中。要稍后更新信息窗口，此外，信息窗口将不会遵循任何正常视图的交互性，例如触摸或手势事件。但是，您可以按照下面的部分描述监听整个信息窗口的通用单击事件......在您的示例中只有TextView。 - user1943012RelativeLayout。 - Driss Bounouar
