This article mainly introduces Android how to customize View to achieve bus track map, the article is very detailed, has a certain reference value, interested friends must read it!

The details are as follows

Overall analysis: horizontal recyclewview,item includes anchor point, site location and site name.

Achieve:

1. Inherit framelayout and implement the construction method:

Public class BusStopPlateView extends FrameLayout {... Public BusStopPlateView (@ NonNull Context context) {super (context); initView (context);} public BusStopPlateView (@ NonNull Context context, @ Nullable AttributeSet attrs) {super (context, attrs); initView (context);} public BusStopPlateView (@ NonNull Context context, @ Nullable AttributeSet attrs, @ AttrRes int defStyleAttr) {super (context, attrs, defStyleAttr); initView (context);} private void initView (Context context) {. / / set recycleview LayoutInflater.from (context) .comparate (R.layout.xxx, this, true) MRecyclerView = (RecyclerView) findViewById (R.id.recycle); mRecyclerView.setLayoutManager (new LinearLayoutManager (context, LinearLayoutManager.HORIZONTAL, false)); mBusStopPlateAdapter = new BusStopPlateAdapter (mStationList); mRecyclerView.setAdapter (mBusStopPlateAdapter);...}

2.recycleview adapter: setting the starting point, setting the end point, setting the lane, setting the subscript of the current car position during initialization.

/ * set the lane * / private void setDriveway (BaseViewHolder helper, BusStopPlateStationInfo item) {if (helper.getAdapterPosition () 1); / / display the gray icon if (aliveBusInfo.getStCount ()) if you have passed the station.

< 0) { GlideUtils.loadImageView(mContext, R.drawable.bus_stop_over_station_min, helper.getView(R.id.iv_stop_not_to)); } else { GlideUtils.loadImageView(mContext, R.drawable.bus_stop_not_to, helper.getView(R.id.iv_stop_not_to)); } } else if ("1".equals(aliveBusInfo.getStStatus())) { // 到站 helper.setVisible(R.id.bus_stop_not_to, false) .setVisible(R.id.bus_stop_reach, true) .setVisible(R.id.iv_admin_index, true) .setVisible(R.id.iv_bus_stop_current, false) .setVisible(R.id.tv_bus_stop_current_num, aliveBusInfo.getStCount() >

1) .setText (R.id.tv_bus_stop_current_num, String.valueOf (aliveBusInfos.size (); / / if the gray icon if (aliveBusInfo.getStCount () < 0) {GlideUtils.loadImageView (mContext, R.drawable.bus_stop_over_station, helper.getView (R.id.iv_admin_index)) is displayed after passing the station. } else {GlideUtils.loadImageView (mContext, R.drawable.bus_stop_not_to, helper.getView (R.id.iv_admin_index));} else {/ / hide bus helper.setVisible (R.id.bus_stop_not_to, false) .setVisible (R.id.bus_stop_reach, false);}}

3. External activity click event: refresh the current location object to the selected location when clicking on the text, refresh the recycleview

MBusStopPlateView.setOnBusStopPlateViewItemClick (new BusStopPlateView.onBusStopPlateViewEvent () {@ Override public void onItemClick (BusStopPlateStationInfo station) {stationId = station.getStId (); stationName = station.getStName (); exportStationInfo (mBusStopPlateView.getStationList ()); aliveBusRefresh (); / / when the information saved in the boarding reminder is inconsistent with the information at the current waiting station, return to the boarding reminder, / / and click on the boarding reminder to determine whether to update the boarding reminder BusRemind remind = SpKeyConfig.getOnRemind () If (remind! = null) {if (remind.getStationId () .equals (stationId) & & remind.getLineId () .equals (mLineId)) {tvOnRemind.setText (cancel reminder); ivOnRemind.setImageResource (R.drawable.bus_icon_onremind_on);} else {tvOnRemind.setText (boarding reminder); ivOnRemind.setImageResource (R.drawable.bus_icon_onremind_off) } @ Override public void onCurrentViewPosition (int x, int y, boolean isVisibility) {mIvPoint.setTranslationX (x-mIvPoint.getWidth () / 2 + 6); mIvPoint.setVisibility (isVisibility? View.VISIBLE: View.INVISIBLE);}}
