如何在android中更新graphview数据
我需要更新通过蓝牙不断接收的graphview数据，我正在使用com.jjoe64.graphview.graphview，我调用了bluetooth connection，服务类中的数据通信逻辑来维护整个应用程序中的蓝牙连接，从服务类我需要更新我的Graphview每当我收到新的蓝牙数据，目前我的Graphview数据与新的数据重叠，我需要绘制3个图形（红色，黄色和蓝色阶段）在同一时间与2系列电压和电流。我每次都需要重置整个数据，请建议，我尝试了重置数据的方法，但没有帮助，请建议解决方案如何在android中更新graphview数据,graph,reset,android-graphview,Graph,Reset,Android Graphview,我需要更新通过蓝牙不断接收的graphview数据，我正在使用com.jjoe64.graphview.graphview，我调用了bluetooth connection，服务类中的数据通信逻辑来维护整个应用程序中的蓝牙连接，从服务类我需要更新我的Graphview每当我收到新的蓝牙数据，目前我的Graphview数据与新的数据重叠，我需要绘制3个图形（红色，黄色和蓝色阶段）在同一时间与2系列电压和电流。我每次都需要重置整个数据，请建议，我尝试了重置数据的方法，但没有帮助，请建议解决方案 if
