烘烤wifi扫描结果会出错

Question

我需要将扫描结果作为吐司，但我认为在吐司的语法中有一个错误，但我无法解决它

wifis = new String[wifiScanList.size()];
for(int i = 0; i < wifiScanList.size(); i++){
wifis[i] = ((wifiScanList.get(i)).toString());

Context context = getApplicationContext();
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, wifis, duration);
toast.show();

该程序让我将wifis类型更改为CharSequence但我需要它作为字符串来获取有关每个wifi网络的信息..任何想法！

Answer 1

这可能对您有用：

  Toast toast = Toast.makeText(context, Arrays.toString(wifis), duration);
