如何将一个扫描列表分配给一个变量？

Question

我已经开发了周围的扫描我的设备现有的WiFi信号，并显示他们的名字和他们的实力以及如下应用：

tv = (TextView) findViewById (R.id.textView1); 

List <ScanResult> results = wm.getScanResults(); 

String otherwifi="The existing network is:\n\n"; 
System.out.println(result.SSID.toString());  
System.out.println(result.level); 
for (ScanResult result: results) { 
    otherwifi+=result.SSID+":"+result.level+"\n"; 
    tv.setText (otherwifi); 
} 

，这是的System.out.println：

>05-11 10:08:30.860: I/System.out(27621): rubelwifii 
>05-11 10:08:30.860: I/System.out(27621): -50 
>05-11 10:08:30.860: I/System.out(27621): aliwifi 
>05-11 10:08:30.860: I/System.out(27621): -92 
>05-11 10:08:30.860: I/System.out(27621): ABDULHAKEEM 
>05-11 10:08:30.860: I/System.out(27621): -55 
>05-11 10:08:30.860: I/System.out(27621): shamwifi 
>05-11 10:08:30.860: I/System.out(27621): -70 
>05-11 10:08:30.860: I/System.out(27621): Fuselage 
>05-11 10:08:30.860: I/System.out(27621): -84 

现在我想预定义它们中的每一个作为变量来使用它们进行进一步处理？

Answer 1

听起来像是你想是这样的：

// pre-defined names and strengths... 
String name1 = "rubelwifii"; 
int strength1 = -50; 
String name2 = "aliwifi"; 
int strength2 = -92; 
String name3 = "ABDULHAKEEM"; 
int strength3 = -55; 
String name4 = "shamwifi"; 
int strength4 = -70; 
String name5 = "Fuselage"; 
int strength5 = -84; 

// a hashmap to store your results 
HashMap<String, ScanResult> hashMap = new HashMap<String, ScanResult>(); 

tv = (TextView) findViewById (R.id.textView1); 

List <ScanResult> results = wm.getScanResults(); 

String otherwifi="The existing network is:\n\n"; 
System.out.println(result.SSID.toString());  
System.out.println(result.level); 
for (ScanResult result: results) { 
    // store the result in a hashmap so you can get at it later 
    hashMap.put(result.SSID.toString(), result); 

    otherwifi+=result.SSID+":"+result.level+"\n"; 
    tv.setText (otherwifi); 
} 

// do something with the first and second result 
ScanResult result1 = hashMap.get(name1); 
ScanResult result2 = hashMap.get(name2); 

// compare strength of #1 to the predefined value... (I'm assuming int is the data type) 
if (result1.level == strength1) { 
    // do something 
} 

// do same for #2 
if (result2.level == strength2) { 
    // do something... 
} 

Answer 2

HashMap hm = new HashMap(); 
// String key; 
for (ScanResult result: results) { 

    // key = cleanYourVarname(result.wifiName); 
    // hm.put(key, result); 

    /* key should be a clean string I assume wifi name as result.SSID */ 
    hm.put(result.SSID.toString(), result); 

} 
// retrieve 
hm.get("rubelwifii");
