高德地图自定义Marker显示文字

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
