如何在Android中的谷歌地圖標記中添加搜索地點圖像

Question

我的概念是，當搜索地點在谷歌地圖中這個地方的圖像是添加在標記，標記是圖像視圖，我用這個鏈接的serch位置代碼http://wptrafficanalyzer.in/blog/android-geocoding-showing-user-input-location-on-google-map-android-api-v2/ 並在此代碼中使用圖像視圖的owen標記。所以我怎麼可以添加圖片

就試試這個：

// 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));
