本篇文章為大家展示了怎么在Android中通過自定義View實(shí)現(xiàn)公交成軌跡圖,內(nèi)容簡明扼要并且容易理解,絕對能使你眼前一亮,通過這篇文章的詳細(xì)介紹希望你能有所收獲。
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:初始化的時候設(shè)置起點(diǎn)設(shè)置終點(diǎn)設(shè)置車道設(shè)置當(dāng)前車位置的下標(biāo)
/** * 設(shè)置車道 */ 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())) // 顯示在過道中的車 .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 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)擊文字的時候?qū)?dāng)前位置對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)上車提醒保存的信息與當(dāng)前候車站點(diǎn)信息不一致時恢復(fù)為上車提醒, // 并在點(diǎn)擊上車提醒是判斷是否更新上車提醒的站點(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); } }
Android是一種基于Linux內(nèi)核的自由及開放源代碼的操作系統(tǒng),主要使用于移動設(shè)備,如智能手機(jī)和平板電腦,由美國Google公司和開放手機(jī)聯(lián)盟領(lǐng)導(dǎo)及開發(fā)。
