安卓簡單網絡連接類型的判斷

基於安卓平臺實現判斷是移動數據連接還是wife連接

文件裏面附帶jar包，請下載

代碼如下：

public class MainActivity extends AppCompatActivity {

    //檢測網絡連接狀態
    private ConnectivityManager manager;

    private LinearLayout ll;
    private AdView adsView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    /**
     * 檢測網絡是否連接
     *
     * @return
     */
    private boolean checkNetworkState() {
        boolean flag = false;
        //得到網絡連接信息
        manager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
        //去進行判斷網絡是否連接
        if (manager.getActiveNetworkInfo() != null) {
            flag = manager.getActiveNetworkInfo().isAvailable();
        }
        if (!flag) {
            setNetwork();
        } else {
            isNetworkAvailable();
        }

        return flag;
    }


    /**
     * 網絡未連接時，調用設置方法
     */
    private void setNetwork() {
        Toast.makeText(this, "wifi is closed!", Toast.LENGTH_SHORT).show();

        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setIcon(R.mipmap.ic_launcher);
        builder.setTitle("網絡提示信息");
        builder.setMessage("網絡不可用，如果繼續，請先設置網絡！");
        builder.setPositiveButton("設置", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Intent intent = null;
                /**
                 * 判斷手機系統的版本！如果API大於10 就是3.0+
                 * 因爲3.0以上的版本的設置和3.0以下的設置不一樣，調用的方法不同
                 */
                if (android.os.Build.VERSION.SDK_INT > 10) {
                    intent = new Intent(android.provider.Settings.ACTION_WIFI_SETTINGS);
                } else {
                    intent = new Intent();
                    ComponentName component = new ComponentName(
                            "com.android.settings",
                            "com.android.settings.WirelessSettings");
                    intent.setComponent(component);
                    intent.setAction("android.intent.action.VIEW");
                }
                startActivity(intent);
            }

            }
        });

        builder.show();
    }

     */
