想在集成的高德地图中实现一个marker受到点击时，图标变大的效果，网上查了好多，要么不符合我的需求，要么语焉不详，干脆自己动手写了个，现在把代码分享出来
aMap.setOnMarkerClickListener(new OnMarkerClickListener() {@Overridepublic boolean onMarkerClick(Marker marker) { marker.showInfoWindow();//显示大图标lastBm = getNormalIcon(marker.getOptions());//记录即将被覆盖的原图，用于以后恢复Marker markerNew = changeMarkerImg(marker);//改变marker的icon，并得到新的marker对象String curMarkerId = markerNew.getId();// 记录下这个图标的id，用于判断再次点击是否还是这个按钮resetMarker(curMarkerId, markerNew);//重置除点击按钮外的所有按钮markerLast = markerNew;// 记录当前marker对象，用于下次点击时判断return true;}});2，更换marker的icon方法private Marker changeMarkerImg(Marker marker) {MarkerOptions options = marker.getOptions();options.getIcon().recycle();// 回收原图片Bitmap bm = BitmapFactory.decodeResource(getResources(),R.drawable.ico_dot);marker.setIcon(BitmapDescriptorFactory.fromBitmap(bm));return marker;}3，重置除点击按钮外的所有按钮private void resetMarker(String curMarkerId, Marker markerNew) {if (null != markerLast) {if (!TextUtils.equals(curMarkerId, markerLast.getId())) {markerLast.setIcon(new BitmapDescriptorFactory().fromBitmap(lastBm));}}}4，生成infoWindow的回调方法@Overridepublic View getInfoWindow(Marker marker) {View infoWindow = getPressView(marker);return infoWindow;}@SuppressLint("NewApi")public View getPressView(Marker marker) {// 小气泡部分View infoWindow = getLayoutInflater().inflate(R.layout.custom_info_window, null);Bitmap bitmap = getPressIcon(marker.getOptions());BitmapDrawable background = new BitmapDrawable(MarkerActivity.this.getResources(), bitmap);infoWindow.findViewById(R.id.info_window).setBackground(background);// 业务部分buttomView.setVisibility(View.VISIBLE);marker.getSnippet();if (marker.getSnippet().contains("加油站")) {// 加油站图片markerName.setText("加油站");} else if (marker.getSnippet().contains("银行")) {// 银行图片markerName.setText("银行");} else if (marker.getSnippet().contains("厕所")) {// 厕所图片markerName.setText("厕所");}markerContent.setText("" + marker.getTitle());return infoWindow;}5，生成默认图标bitmap的方法private Bitmap getNormalIcon(MarkerOptions options) {Bitmap bm = null;if (options.getSnippet().contains("加油站")) {// 加油站图片bm = BitmapFactory.decodeResource(getResources(),R.drawable.ico_refuel_normal);} else if (options.getSnippet().contains("银行")) {// 银行图片bm = BitmapFactory.decodeResource(getResources(),R.drawable.ico_money_normal);} else if (options.getSnippet().contains("厕所")) {// 厕所图片bm = BitmapFactory.decodeResource(getResources(),R.drawable.ico_toilet_normal);}return bm;}
