如何通过这个协议public class Protocol { private static final String PROTOCOL_HEADER = "10Hz,"; private static final String PROTOCOL_SEPARATOR = ","; private static final String PROTOCOL_NEWLINE = "\r\n"; private int frameNumber; private int systemState; private int northProgress; private float headingAngle; private float pitchAngle; private float rollAngle; private float realTimeData; public Protocol(int frameNumber, int systemState, int northProgress, float headingAngle, float pitchAngle, float rollAngle, float realTimeData) { this.frameNumber = frameNumber; this.systemState = systemState; this.northProgress = northProgress; this.headingAngle = headingAngle; this.pitchAngle = pitchAngle; this.rollAngle = rollAngle; this.realTimeData = realTimeData; } public String toString() { StringBuilder builder = new StringBuilder(); builder.append(PROTOCOL_HEADER); builder.append(frameNumber).append(PROTOCOL_SEPARATOR); builder.append(systemState).append(PROTOCOL_SEPARATOR); builder.append(northProgress).append(PROTOCOL_SEPARATOR); builder.append(headingAngle).append(PROTOCOL_SEPARATOR); builder.append(pitchAngle).append(PROTOCOL_SEPARATOR); builder.append(rollAngle).append(PROTOCOL_SEPARATOR); builder.append(realTimeData).append(PROTOCOL_NEWLINE); return builder.toString(); }}和这段代码 // 更新进度条 int progressValueR = 0; if(runFlag==5 || runFlag==10){ Log.i(TAG,"runFlag value" +runFlag); progressValueR = 100; progressFlag = false; }else{ progressValueR = (progressValue/21); // 大概2000帧多一点可以寻北完成 if(progressValueR<0) progressValueR = 0; if(progressValueR>=100) progressValueR=98; } setProgressValue(progressValueR); Log.i(TAG,"Progress value" +progressValueR); }将进度条产生值

通过这个协议和代码，我们可以将实时数据打包成一个字符串。可以在代码中创建一个Protocol对象，设置好各项数据，然后调用对象的toString()方法，就可以得到一个符合协议要求的字符串。

在这段代码中，通过计算progressValueR的值，来更新进度条的显示。通过将progressValueR的值设置给进度条，就可以让进度条显示相应的进度。

具体实现方式可能需要根据代码的具体情况进行调整和修改。

如何根据这个协议public class Protocol { private static final String PROTOCOL_HEADER = "10Hz,"; private static final String PROTOCOL_SEPARATOR = ","; private static final String PROTOCOL_NEWLINE = "\r\n"; private int frameNumber; private int systemState; private int northProgress; private float headingAngle; private float pitchAngle; private float rollAngle; private float realTimeData; public Protocol(int frameNumber, int systemState, int northProgress, float headingAngle, float pitchAngle, float rollAngle, float realTimeData) { this.frameNumber = frameNumber; this.systemState = systemState; this.northProgress = northProgress; this.headingAngle = headingAngle; this.pitchAngle = pitchAngle; this.rollAngle = rollAngle; this.realTimeData = realTimeData; } public String toString() { StringBuilder builder = new StringBuilder(); builder.append(PROTOCOL_HEADER); builder.append(frameNumber).append(PROTOCOL_SEPARATOR); builder.append(systemState).append(PROTOCOL_SEPARATOR); builder.append(northProgress).append(PROTOCOL_SEPARATOR); builder.append(headingAngle).append(PROTOCOL_SEPARATOR); builder.append(pitchAngle).append(PROTOCOL_SEPARATOR); builder.append(rollAngle).append(PROTOCOL_SEPARATOR); builder.append(realTimeData).append(PROTOCOL_NEWLINE); return builder.toString(); }}解析这个数据举例： 1,10,0,10.56,0.1234,0.23456,75.0

这个协议的数据结构是固定的，每个字段的意义如下：

- frameNumber：帧数
- systemState：系统状态
- northProgress：北向进度
- headingAngle：航向角
- pitchAngle：俯仰角
- rollAngle：横滚角
- realTimeData：实时数据

根据这个协议，数据 "1,10,0,10.56,0.1234,0.23456,75.0" 可以解析为：

- frameNumber = 1
- systemState = 10
- northProgress = 0
- headingAngle = 10.56
- pitchAngle = 0.1234
- rollAngle = 0.23456
- realTimeData = 75.0

如果你想要解析更多的数据，只需要将数据按照协议中定义的格式进行拼接，然后再使用相应的方法进行解析即可。

public class ProtocolData { private static final String PROTOCOL_HEADER = "10Hz"; //输出10HZ private static final String PROTOCOL_SEPARATOR = ","; //英文“，”分隔 private static final String PROTOCOL_NEWLINE = "\r\n"; //\r\n结束 private int frameNumber; //帧序号 private byte systemState; //系统状态 private byte northProgress; //寻北进度 private float headingAngle; //航向角 private float pitchAngle; //俯仰角 private float rollAngle; //横滚角 private float realTimeData; //数据更新 public ProtocolData(int frameNumber, byte systemState, byte northProgress, float headingAngle, float pitchAngle, float rollAngle, float realTimeData) { this.frameNumber = frameNumber; this.systemState = systemState; this.northProgress = northProgress; this.headingAngle = headingAngle; this.pitchAngle = pitchAngle; this.rollAngle = rollAngle; this.realTimeData = realTimeData; } public String toString() { StringBuilder builder = new StringBuilder(); builder.append(PROTOCOL_HEADER); builder.append(frameNumber).append(PROTOCOL_SEPARATOR); builder.append(systemState).append(PROTOCOL_SEPARATOR); builder.append(northProgress).append(PROTOCOL_SEPARATOR); builder.append(headingAngle).append(PROTOCOL_SEPARATOR); builder.append(pitchAngle).append(PROTOCOL_SEPARATOR); builder.append(rollAngle).append(PROTOCOL_SEPARATOR); builder.append(realTimeData).append(PROTOCOL_NEWLINE); return builder.toString(); }

这段代码看起来是一个 Java 类，名为 ProtocolData。它有一些常量，包括协议头、分隔符和换行符。它还有一些实例变量，包括帧序号、系统状态、寻北进度、航向角、俯仰角、横滚角和实时数据。它有一个构造函数，用于初始化这些实例变量。它还有一个 toString 方法，用于将实例变量格式化成一个字符串，以便发送到其他设备。
