如何將一個掃描列表分配給一個變量？

Question

我已經開發了周圍的掃描我的設備現有的WiFi信號，並顯示他們的名字和他們的實力以及如下應用：

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); 
} 

，這是的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 

現在我想預定義它們中的每一個作爲變量來使用它們進行進一步處理？

Answer 1

聽起來像是你想是這樣的：

// 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");
