I don't think it is possible to switch to mobile data network when WiFi is enabled. Perhaps you should silently disable the WiFi (from code) and wait for the 3G network to establish. Once your required task is done, turn the WiFi on again and your 3G network will be disconnected.

我认为以下应该工作......
WifiManager wm = null;
WifiManager.WifiLock wfl = null;
// To disable wi-fi
wm = (WifiManager) this.getSystemService(Context.WIFI_SERVICE);
if (wm != null) {
wfl = wm.createWifiLock(WifiManager.WIFI_MODE_SCAN_ONLY, "myWifiLock");
Boolean result = wm.setWifiEnabled(false);
Log.d(TAG, "wm.setWifiEnabled(false) result: " + result);
}
// To re-enable wi-fi
if (wfl != null)
wfl.release();
if (wm != null) {
Boolean result = wm.setWifiEnabled(true);
Log.d(TAG, "wm.setWifiEnabled(true) result: " + result);
}

这是一个可以在您的代码中启用和禁用的代码！
wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
Runnable runnable = new Runnable() {
// ginetai o kwdikas gia to anoigma kai to klisimo tou wifi
@Override
public void run() {
// new LongOperation().execute();
for (int i = 0; i <= 150; i++) {
try {
Thread.sleep(1000);
if (i >= 0 && i <18){
wifi.setWifiEnabled(true);
// wifi.setWifiEnabled(false);// Disabling WiFi
}
else if (i>= 18 && i < 40){
wifi.setWifiEnabled(true);
// wifi.setWifiEnabled(false); // Enabling WiFi
}
else if (i>= 40 && i < 58){
// wifi.setWifiEnabled(true); // Disabling WiFi
wifi.setWifiEnabled(false);
}
else if (i>= 58 && i < 78){
wifi.setWifiEnabled(true);
//wifi.setWifiEnabled(false); // Enabling WiFi
}
else{
// wifi.setWifiEnabled(true);
wifi.setWifiEnabled(false);// Disabling WiFi
}
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
};
new Thread(runnable).start();

只是禁用Wi-Fi？这两个过程都是自动的：启用时连接 Wi-Fi 网络，并在没有 Wi-Fi 连接时获得 3G。
