记忆力下降的厉害,年前做的demo,年后就忘了差不多了,当然也有一部分原因是因为这个年假确实有点长,,,,whatever,还是写个博客记录一下,忘了也有地方找 结果,还是忘了,,, 贴两个地址吧 谷歌官方文档 如何调试wear应用 wear应用和手机端通过蓝牙互相传数据方面,有个数据层,手机端数据改变发送到数据层,数据层会随之改变,并在wear应用打开的时候通知监听 wear方面的监听 package com.example.win.aodwear2; import android.content.SharedPreferences; import android.util.Log; import android.widget.Toast; import com.google.android.gms.wearable.Asset; import com.google.android.gms.wearable.DataEvent; import com.google.android.gms.wearable.DataEventBuffer; import com.google.android.gms.wearable.DataItem; import com.google.android.gms.wearable.DataMap; import com.google.android.gms.wearable.DataMapItem; import com.google.android.gms.wearable.MessageEvent; import com.google.android.gms.wearable.WearableListenerService; /** * Created by win on 2019/12/25. */ public class DataLayerListenerService extends WearableListenerService{ private CtrApp app; @Override public void onCreate() { super.onCreate(); app = (CtrApp) getApplication(); } @Override public void onMessageReceived(MessageEvent messageEvent) { super.onMessageReceived(messageEvent); System.out.println("消息========="); } @Override public void onDataChanged(DataEventBuffer dataEventBuffer) { System.out.println("收到的数据变化ondatachanged222==="); Log.i("info", "数据发生变化喽"); for (DataEvent event : dataEventBuffer) { if (event.getType() == DataEvent.TYPE_CHANGED) { String typeString = event.getDataItem().getUri().getPath(); DataItem item = event.getDataItem(); DataMap map = DataMapItem.fromDataItem(item).getDataMap(); //item.getUri().getPath().compareTo("/count") == 0 if ("/image".equals(typeString)) { Log.i("info", "是图片"); Asset mAsset = map.getAsset("asset"); } else if (typeString.compareTo("/bledata") == 0){ app.dev_name = map.getString("dev_name"); app.bt_key = map.getString("bt_key"); app.isbleconnect=0; SharedPreferences.Editor editor = getSharedPreferences("login", MODE_PRIVATE).edit(); editor.putString("dev_name", app.dev_name); editor.putString("bt_key", app.bt_key); editor.commit(); System.out.println("数据变化类型事件:222"+app.dev_name+"=="+app.bt_key); Toast.makeText(getApplicationContext(),"车辆更换,正在重新连接蓝牙",Toast.LENGTH_LONG).show(); //Log.i("info", "数据变化类型事件:" + getString); } } else if (event.getType() == DataEvent.TYPE_DELETED) { Log.i("info", "数据删除"); } } // for (DataEvent event : dataEventBuffer) { // if (event.getType() == DataEvent.TYPE_CHANGED) { // // DataItem changed // DataItem item = event.getDataItem(); // if (item.getUri().getPath().compareTo("/count") == 0) { // DataMap dataMap = DataMapItem.fromDataItem(item).getDataMap(); // String date = dataMap.getString("btkey"); // System.out.println("收到的数据==="+date); // Toast.makeText(this,date,Toast.LENGTH_SHORT).show(); // // //updateCount(dataMap.getInt(COUNT_KEY)); // } // } else if (event.getType() == DataEvent.TYPE_DELETED) { // // DataItem deleted // } // } } }手机端同步数据层: //与手表通讯部分,暂不开启 public int iswearopen=0; public void changeDevName(String dev_name,String bt_key){ if (iswearopen==0){ return; } SharedPreferences read = getSharedPreferences("login", MODE_PRIVATE); String olddev_name = read.getString("dev_name", ""); if(!TextUtils.isEmpty(dev_name)&&!TextUtils.isEmpty(olddev_name)&&!dev_name.equals(olddev_name)){ if (isgooglecon==1) { PutDataMapRequest mapRequest = PutDataMapRequest.create("/bledata"); DataMap dataMap = mapRequest.getDataMap(); dataMap.putString("dev_name", dev_name); dataMap.putString("bt_key", bt_key); mapRequest.setUrgent(); PutDataRequest dataRequest = mapRequest.asPutDataRequest(); dataRequest.setUrgent(); Wearable.DataApi.putDataItem(mGoogleAppiClient, dataRequest).setResultCallback(new ResultCallback() { @Override public void onResult(DataApi.DataItemResult arg0) { if (!arg0.getStatus().isSuccess()) { } else { Log.i("info", "发送成功了"); //Toast.makeText(MainActivity.this, "Notification Success", Toast.LENGTH_LONG).show(); } } }); } else { Log.i("info", "没连上"); } } }
