如何在android的谷歌地图标记中添加搜索地点图像

Question

我的概念是，当在谷歌地图中搜索地点时，这个地点图像被添加到标记中，标记是图像视图，我使用来自这个链接的搜索位置代码 http://wptrafficanalyzer.in/blog/android-geocoding-showing-user-input-location-on-google-map-android-api-v2/ 并在此代码中使用欧文标记，即图像视图。那么我如何添加图像

试试这个：

 // Uses a custom icon.
    mIndia = mMap.addMarker(new MarkerOptions()
        .position(SYDNEY)
        .title("Sydney")
        .snippet("Population: 4,627,300")
        .icon(BitmapDescriptorFactory.fromResource(R.drawable.arrow)));

As this just replaces the marker with an image you might want to use a Canvas to draw more complex and fancier stuff:

Bitmap.Config conf = Bitmap.Config.ARGB_8888;
Bitmap bmp = Bitmap.createBitmap(80, 80, conf);
Canvas canvas1 = new Canvas(bmp);

// paint defines the text color,
// stroke width, size
Paint color = new Paint();
color.setTextSize(35);
color.setColor(Color.BLACK);

//modify canvas
canvas1.drawBitmap(BitmapFactory.decodeResource(getResources(),
    R.drawable.user_picture_image), 0,0, color);
canvas1.drawText("User Name!", 30, 40, color);

//add marker to Map
mMap.addMarker(new MarkerOptions().position(USER_POSITION)
    .icon(BitmapDescriptorFactory.fromBitmap(bmp))
    // Specifies the anchor to be at a particular point in the marker image.
    .anchor(0.5f, 1));
