我按照以下代码将scanresult存储到列表中:
List<ScanResult> results = wifi.getScanResults(); sb = new StringBuilder(); try { for(int i = 0; i < results.size(); i++){ sb.append(new Integer(i+1).toString() + "."); sb.append("SSID:-").append((results.get(i).SSID).toString()); sb.append("BSSID:-").append((results.get(i).BSSID).toString()); sb.append("Level:-").append((results.get(i).level)); sb.append("Frequency:-").append((results.get(i).frequency)); sb.append("\n\n"); } textStatus.setText(""); textStatus.append("\n\n\n"); textStatus.append(sb); }
我想根据信号强度(级别)对此结果进行排序,因此我创建了一个具有数据级别和Mac的2D数组.所以我为此编写了代码:
String RSSi[][]=new String[2][results.size()]; for(int i = 0; i <results.size(); i++){ RSSi[0][i] = String.valueOf(results.get(i).level); RSSi[1][i]= results.get(i).BSSID; } StringBuilder tmp=new StringBuilder(); Arrays.sort(RSSi,new Comparator<String[]>() { @Override public int compare(String[] str1,String[] str2) { final String lv1= str1[0]; final String lv2= str2[0]; return lv1.compareTo(lv2); } );
解决方法
试试这个
Comparator<ScanResult> comparator = new Comparator<ScanResult>() { @Override public int compare(ScanResult lhs,ScanResult rhs) { return (lhs.level <rhs.level ? -1 : (lhs.level==rhs.level ? 0 : 1)); } } List<ScanResult> results = wifi.getScanResults(); Collections.sort(results,comparator); //Here your list is sorted by level
