監聽手機網絡狀態

監聽手機網絡狀態

1、實現接收網絡狀態變化的廣播接收者

public class NetworkChangedReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        int netWorkStates = NetworkUtils.getNetWorkState(context);

        if (SystemUtils.isAppTopRunning(context)){
            switch (netWorkStates) {
                case NetworkUtils.TYPE_NONE:
                    ToastUtils.showLongToast(context, R.string.internet_disconnect);
                    break;
                case NetworkUtils.TYPE_MOBILE:
//                    ToastUtils.showShortToast(context,R.string.current_use_4g);
                    break;
                case NetworkUtils.TYPE_WIFI:
//                    ToastUtils.showShortToast(context,R.string.wifi_connected);
                    break;
                default:
                    break;
            }
        }

    }
}

網絡狀態判斷工具類

/**
 * 網絡狀態工具類
 * @describe
 *
 * @author Jeff
 * @date 2018/2/7.
 */
public class NetworkUtils {
    public static final int TYPE_NONE = -1;//沒網
    public static final int TYPE_MOBILE = 0;//移動網絡
    public static final int TYPE_WIFI = 1;//WIFI

    /**
     * 獲取網絡狀態
     *
     * @param context
     * @return one of TYPE_NONE, TYPE_MOBILE, TYPE_WIFI
     * @describe need access permission android.permission.ACCESS_NETWORK_STATE
     */
    public static int getNetWorkState(Context context) {
        ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
        if (activeNetworkInfo == null || !activeNetworkInfo.isConnected()) {
            return TYPE_NONE;//沒網
        }

        int type = activeNetworkInfo.getType();
        switch (type) {
            case ConnectivityManager.TYPE_MOBILE:
                return TYPE_MOBILE;//移動數據
            case ConnectivityManager.TYPE_WIFI:
                return TYPE_WIFI;//WIFI
            default:
                break;
        }
        return TYPE_NONE;
    }
}

2、在清單文件中註冊廣播接收者，並聲明相關權限

註冊

<receiver android:name=".common.receiver.NetworkChangedReceiver">
    <intent-filter>
        <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
    </intent-filter>
</receiver>

權限

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
