wifi密码破解功能（只能破解部分加密方式的wifi）
SSID是wifi名称 ，密码是wifi密码，（要有网络情况下才能破解）
主要代码：
public class MainActivity extends Activity
{
Context mContext = this;
TextView textView;
WifiStatus wifiStatus;
Handler mHandler;
final int UPDATE_TEXT = 1;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = (TextView) findViewById(R.id.content);
wifiStatus = new WifiStatus(mContext);
mHandler = new Handler()
{
public void handleMessage(Message msg) {
switch (msg.what) {
case UPDATE_TEXT:
textView.setText(msg.obj.toString());
break;
}
}
};
showWifiStatus();
}
public void btnWifi(View v)
{
try {
Toast.makeText(mContext, "查询中...", Toast.LENGTH_SHORT).show();
new Thread(new Runnable() {
@Override
public void run() {
try {
Message msg = new Message();
msg.what = UPDATE_TEXT;
msg.obj = new mkQuerypwd().getpwd();
mHandler.sendMessage(msg);
} catch (Exception e) {
e.printStackTrace();
}
}
}).start();
} catch (Exception e) {
e.printStackTrace();
}
}

}
