方法一：
调用：
Marker localMarker=mAMap.addMarker(new MarkerOptions()
.position(localLatLng)
//.icon(BitmapDescriptorFactory.fromBitmap(BitmapFactory.decodeResource(getResources(), R.drawable.map_location_icon))));
/*.icon(BitmapDescriptorFactory.
fromView(getMyView(pm.getPm()+""))));*/
.icon(BitmapDescriptorFactory.fromBitmap(getMyBitmap(pm.getPm()+""))));
localMarker.setObject(pm);
getMyBitmap方法：
protected Bitmap getMyBitmap(String pm_val) {
Bitmap bitmap = BitmapDescriptorFactory.fromResource(
R.drawable.map_location_icon).getBitmap();
bitmap = Bitmap.createBitmap(bitmap, 0 ,0, bitmap.getWidth(),
bitmap.getHeight());
Canvas canvas = new Canvas(bitmap);
TextPaint textPaint = new TextPaint();
textPaint.setAntiAlias(true);
textPaint.setTextSize(22f);
textPaint.setColor(getResources().getColor(R.color.blue));
canvas.drawText(pm_val, 17, 35 ,textPaint);// 设置bitmap上面的文字位置
return bitmap;
}
方法二：
布局文件：
mymarker.xml
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/map_location_icon"
android:scaleType="centerCrop"/>
android:id="@+id/marker_tv_val"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10px"
android:layout_marginTop="7px"
android:textColor="@android:color/black"
/>
2调用：
Marker localMarker=mAMap.addMarker(new MarkerOptions()
.position(localLatLng)
//.icon(BitmapDescriptorFactory.fromBitmap(BitmapFactory.decodeResource(getResources(), R.drawable.map_location_icon))));
/*.icon(BitmapDescriptorFactory.
fromView(getMyView(pm.getPm()+""))));*/
.icon(BitmapDescriptorFactory.fromBitmap(getMyBitmap(pm.getPm()+""))));
localMarker.setObject(pm);
3：getMyView方法
protected View getMyView(String pm_val) {
View view=getLayoutInflater().inflate(R.layout.mymarker, null);
TextView tv_val=(TextView) view.findViewById(R.id.marker_tv_val);
tv_val.setText(pm_val);
return view;
}
第一种方法比较简洁一点
