Android之高仿飛鴿傳輸熱點建立與搜索模塊
這兩天，無心中看到飛鴿傳書的wifi熱點建立與搜索模塊，因而乎很蛋疼的還原了一下他的這一小模塊代碼，感受效果差很少，跟你們分享一下：java
源碼下載地址:http://download.csdn.net/download/weidi1989/5293352android
咱們先來看看效果圖：網絡
1.山寨機主界面app
2.進應用就會自動搜索wifi，這個動畫效果截屏變形了。將就一下吧
ide
3.搜索結果顯示
函數
4.鏈接上我另一臺山寨機建立的熱點
學習
5.正在建立熱點
動畫
6.熱點建立成功，關於那個黑黑的gif動畫，我試了三種方法：①.網上導了那個很氾濫的包，不行，②.用Movie實現的動畫，仍是不行，在有的機器上會花屏，③.就是下面這個效果了，自定義的一個view，因爲圖片是透明的，因此黑色底沒有解決。
ui
下面是幾個關鍵類的代碼：this
1.咱們先來看看這個廣播：WTBroadcast，經過這個廣播，能夠及時更新咱們的界面顯示信息。重點是「android.net.wifi.WIFI_STATE_CHANGED」 與「android.net.wifi.STATE_CHANGE」兩個狀態的區別
/**
* wifi狀態監聽廣播
*
* @author way
*
*/
public class WTBroadcast extends BroadcastReceiver {
public static ArrayList<EventHandler> ehList = new ArrayList();
public void onReceive(Context paramContext, Intent paramIntent) {
if (paramIntent.getAction().equals("android.net.wifi.SCAN_RESULTS")) {
// 搜索到wifi熱點結果廣播
Log.i("WTScanResults", "android.net.wifi.SCAN_RESULTS");
// 遍歷通知各個監聽接口
for (int j = 0; j < ehList.size(); j++)
((EventHandler) ehList.get(j)).scanResultsAvailable();
} else if (paramIntent.getAction().equals(
"android.net.wifi.WIFI_STATE_CHANGED")) {
// wifi打開或關閉廣播(不須要鏈接上一個SSID)
Log.e("WTScanResults", "android.net.wifi.WIFI_STATE_CHANGED");
for (int j = 0; j < ehList.size(); j++)
((EventHandler) ehList.get(j)).wifiStatusNotification();
} else if (paramIntent.getAction().equals(
"android.net.wifi.STATE_CHANGE")) {
// 鏈接上一個SSID後發出的廣播，與android.net.wifi.WIFI_STATE_CHANGED有必定區別
Log.e("WTScanResults", "android.net.wifi.STATE_CHANGE");
for (int i = 0; i < ehList.size(); i++)
((EventHandler) ehList.get(i)).handleConnectChange();
}
}
/**
* 用來更新的接口
*
* @author way
*
*/
public static abstract interface EventHandler {
public abstract void handleConnectChange();
public abstract void scanResultsAvailable();
public abstract void wifiStatusNotification();
}
}
2.接下來是主Activity了：WTActivity，在這個Activity中，咱們來處理各類界面事件，同時根據wifi狀態變化，動態更新界面，值得學習的是自定義view和handler事件處理，還有超時線程的理論。內容比較多，我把它綜合到一個類中，其實能夠把一些經常使用的函數放在Application類中。
