這篇文章主要為大家詳細(xì)介紹了Android自定義View實(shí)現(xiàn)公交成軌跡圖,具有一定的參考價(jià)值,感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了Android自定義View實(shí)現(xiàn)公交成軌跡圖的具體代碼,供大家參考,具體內(nèi)容如下

總體分析下:水平方向recyclewview,item包含定位點(diǎn),站臺(tái)位置和站臺(tái)名稱。

下面看實(shí)現(xiàn):

1.繼承framelayout,實(shí)現(xiàn)構(gòu)造方法:

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) {
 ...
 //設(shè)置recycleview
 LayoutInflater.from(context).inflate(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適配器:初始化的時(shí)候設(shè)置起點(diǎn)設(shè)置終點(diǎn)設(shè)置車(chē)道設(shè)置當(dāng)前車(chē)位置的下標(biāo)

 /**
 * 設(shè)置車(chē)道
 */
 private void setDriveway(BaseViewHolder helper, BusStopPlateStationInfo item) {
 if (helper.getAdapterPosition() <= adminCurrentIndex) {
  helper.getView(R.id.v_daolu).setSelected(true);
  helper.getView(R.id.iv_jiantou).setSelected(true);
 } else {
  helper.getView(R.id.v_daolu).setSelected(false);
  helper.getView(R.id.iv_jiantou).setSelected(false);
 }
 }

 /**
 * 設(shè)置起點(diǎn)
 */
 private void setStartStation(BaseViewHolder helper, BusStopPlateStationInfo item) {
 helper.setVisible(R.id.v_daolu, false)
  .setBackgroundRes(R.id.iv_jiantou, R.drawable.bg_busstop_vdaolu_start);
 }

 /**
 * 設(shè)置終點(diǎn)
 */
 private void setEndStation(BaseViewHolder helper, BusStopPlateStationInfo item) {
 helper.setBackgroundRes(R.id.iv_jiantou, R.drawable.bg_busstop_vdaolu_end)
  .setBackgroundRes(R.id.v_daolu, R.drawable.bg_busstop_vdaolu_end)
  .setVisible(R.id.v_zhanwei, true)
  .setVisible(R.id.v_daoli_zhanwei, false);
 }

 /**
 * 設(shè)置當(dāng)前所在站點(diǎn)
 */
 private void setCurrentStation(BaseViewHolder helper, BusStopPlateStationInfo item) {
 mCurrentView = helper.getConvertView();
 helper.setVisible(R.id.bus_stop_reach, true)
  .setVisible(R.id.iv_bus_stop_current, false)
  .setVisible(R.id.tv_bus_stop_current_num, false)
  .setVisible(R.id.iv_current_point, true)
  .setVisible(R.id.iv_admin_index, true)
  // 顯示占位符,用于顯示一半的灰色
  .setBackgroundRes(R.id.v_daoli_zhanwei, R.drawable.bg_busstop_vdaolu)
  .setVisible(R.id.v_daoli_zhanwei, true);
//  .setTextColor(R.id.tv_bus_station_name, Color.parseColor("#3D93FD"));

 Glide.with(mContext)
  .load(R.drawable.bus_icon_fangxiang_current)
  .crossFade()
  .into((ImageView) helper.getView(R.id.iv_current_point));

 List<AliveBusInfo> aliveBusInfos = item.getAliveBusInfos();
 if (aliveBusInfos != null && aliveBusInfos.size() != 0) {
  AliveBusInfo aliveBusInfo = aliveBusInfos.get(0);
  if ("1".equals(aliveBusInfo.getStStatus()) && aliveBusInfo.getStName().equals(item.getStName())) {
  helper.setVisible(R.id.iv_admin_index, false)
   .setVisible(R.id.iv_bus_stop_current, true)
   .setImageResource(R.id.iv_bus_stop_current, R.drawable.bus_stop_current);
  }
 } else {
  Glide.with(mContext)
   .load(R.drawable.icon_admin_current_station)
   .crossFade()
   .into((ImageView) helper.getView(R.id.iv_admin_index));
 }

 }

 /**
 * 設(shè)置公交所在站點(diǎn)
 */
 private void setBusStation(BaseViewHolder helper, BusStopPlateStationInfo item) {
 List<AliveBusInfo> aliveBusInfos = item.getAliveBusInfos();
 if (aliveBusInfos != null && aliveBusInfos.size() != 0) {
  AliveBusInfo aliveBusInfo = aliveBusInfos.get(0);
  if ("0".equals(aliveBusInfo.getStStatus())) {
  // 在車(chē)道上
  helper.setVisible(R.id.bus_stop_not_to, true)
   .setVisible(R.id.bus_stop_reach, false)
   .setText(R.id.tv_stop_not_to_num, String.valueOf(aliveBusInfos.size()))
   // 顯示在過(guò)道中的車(chē)
   .setVisible(R.id.iv_stop_not_to, aliveBusInfos.size() != 0)
   // 是否顯示數(shù)字
   .setVisible(R.id.tv_stop_not_to_num, aliveBusInfos.size() > 1);
  // 如果已經(jīng)過(guò)站 顯示灰色圖標(biāo)
  if (aliveBusInfo.getStCount() < 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()));
  // 如果已經(jīng)過(guò)站 顯示灰色圖標(biāo)
  if (aliveBusInfo.getStCount() < 0) {
   GlideUtils.loadImageView(mContext, R.drawable.bus_stop_over_station, helper.getView(R.id.iv_admin_index));
  } else {
   GlideUtils.loadImageView(mContext, R.drawable.bus_stop_not_to, helper.getView(R.id.iv_admin_index));
  }
  }
 } else {
  // 隱藏公交車(chē)
  helper.setVisible(R.id.bus_stop_not_to, false)
   .setVisible(R.id.bus_stop_reach, false);
 }
 }

3.外部activity的點(diǎn)擊事件:點(diǎn)擊文字的時(shí)候?qū)?dāng)前位置對(duì)象刷新到選擇的位置,刷新recycleview

mBusStopPlateView.setOnBusStopPlateViewItemClick(new BusStopPlateView.onBusStopPlateViewEvent() {
  @Override
  public void onItemClick(BusStopPlateStationInfo station) {
  stationId = station.getStId();
  stationName = station.getStName();
  exportStationInfo(mBusStopPlateView.getStationList());
  aliveBusRefresh();

  //當(dāng)上車(chē)提醒保存的信息與當(dāng)前候車(chē)站點(diǎn)信息不一致時(shí)恢復(fù)為上車(chē)提醒,
  // 并在點(diǎn)擊上車(chē)提醒是判斷是否更新上車(chē)提醒的站點(diǎn)
  BusRemind remind = SpKeyConfig.getOnRemind();
  if (remind != null) {
   if (remind.getStationId().equals(stationId) &&
    remind.getLineId().equals(mLineId)) {
   tvOnRemind.setText("取消提醒");
   ivOnRemind.setImageResource(R.drawable.bus_icon_onremind_on);
   } else {
   tvOnRemind.setText("上車(chē)提醒");
   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);
  }
 }
