<span style="font-family: Arial, Helvetica, sans-serif;">自定义Marker布局</span>

<?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" >
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="#fea531"
        android:gravity="center"
        android:orientation="horizontal" >
        <ImageView
            android:id="@+id/img_hotel_image"
            android:layout_width="25dp"
            android:layout_height="25dp"
            android:padding="2dip"
            android:scaleType="fitXY"
            android:src="@drawable/hotel_pic" />
        <TextView
            android:id="@+id/tv_hotel_price"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="5dip"
            android:textColor="#ffffff"
            android:textSize="14dp" />
    </LinearLayout>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:orientation="horizontal" >
        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/custom_marker_triangle" />
    </LinearLayout>
</LinearLayout>

下面这段代码是关键，我们需要把自定义的view转换成Bitmap，MarkerOptions中的icon参数是Bitmap，自定义marker是很常用的

private Bitmap getViewBitmap(View addViewContent) {
 
        addViewContent.setDrawingCacheEnabled(true);
 
        addViewContent.measure(View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED), View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
        addViewContent.layout(0, 0, addViewContent.getMeasuredWidth(), addViewContent.getMeasuredHeight());
 
        addViewContent.buildDrawingCache();
        Bitmap cacheBitmap = addViewContent.getDrawingCache();
        Bitmap bitmap = Bitmap.createBitmap(cacheBitmap);
 
        return bitmap;
    }

加载Marker

                    latLng = new LatLng(info.getBaiDuLat(), info.getBaiDuLng());
<span style="white-space:pre">			</span>// 图标
<span style="white-space:pre">			</span>View view = LayoutInflater.from(getApplicationContext()).inflate(
<span style="white-space:pre">					</span>R.layout.markerstation_layout, null);
<span style="white-space:pre">			</span>TextView tv_hotel_price = (TextView) view
<span style="white-space:pre">					</span>.findViewById(R.id.tv_hotel_price);
<span style="white-space:pre">			</span>tv_hotel_price.setText(info.getStationName());
<span style="white-space:pre">			</span>BitmapDescriptor markerIcon = BitmapDescriptorFactory
<span style="white-space:pre">					</span>.fromBitmap(getViewBitmap(view));
<span style="white-space:pre">			</span>overlayOptions = new MarkerOptions().position(latLng).icon(markerIcon)
<span style="white-space:pre">					</span>.zIndex(5);
<span style="white-space:pre">			</span>marker = (Marker) (mBaiduMap.addOverlay(overlayOptions));
