在绘制功能上加了标注显示后，根据功能实现删除，但是根据示例里面的清除方式后，标注内容没有被清除，只有点线面被清除了，但是测高功能得到的线段没有被清除，想问一下是要怎么写，用什么方法
这是实现的代码
//距离量算
fab_cj.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
closeAnalysis();
AnalysisTypeArea = 0;
// line.setBackgroundResource(R.color.red);
// area.setBackgroundResource(R.color.purple);
startMeasureAnalysis();
}
});
//面积量算
fab_cm.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// closeAnalysis();
AnalysisTypeArea = 1;
// line.setBackgroundResource(R.color.aqua);
// area.setBackgroundResource(R.color.blanchedalmond);
startSurearea();
}
});
//高度量算
fab_cg.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
closeAnalysis();
AnalysisTypeArea = 2;
// line.setBackgroundResource(R.color.aqua);
// area.setBackgroundResource(R.color.blanchedalmond);
startMeasureHeight();
}
});
//清除
fab_qc.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
closeAnalysis();
}
});
//关闭分析
public void closeAnalysis()
