整合大量開源庫溫習基礎項目（一）

轉載請注明出處：王亟亟的大牛之路

有一段時間沒好好寫文章了，然後就把之前的那個滑動解鎖的內容又繼續升級了下，準備在這之後做進一步的衍生，上次的例子http://blog.csdn.net/ddwhan0123/article/details/48781475

這一次例子的效果

項目結構：

完成如下功能-進入APP-對網絡，用戶狀態的判斷-跳轉至登錄/註冊的介面-登錄狀態的判斷(註冊部分邏輯未寫，按照實際需求做吧)

為什麼要這麼做？
1.沒事幹的時候找點事情做做，溫習一下技能
2.在實操的過程中對自己的實現方式做改進（主要是設計和實現的思路，優化什麼的之後再做吧）

廢話不多直接上代碼（適配做的是谷歌兒子7的，如果正常手機看不習慣的話，請見諒）

基類 BaseActivity

public abstract class BaseActivity extends Activity {

    protected static final String TAG = BaseActivity.class.getName() + ".TAG";

    Intent network;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(getLayout());

        findById();

        setListener();

        logic();

        //监听网络
        if (network == null) {
            network = new Intent(BaseActivity.this, NetworkStateService.class);
        }
        startService(network);
    }

    //FindById
    protected abstract void findById();

    //setListener
    protected abstract void setListener();

    //Logic
    protected abstract void logic();

    protected abstract int getLayout();

    //判断是否有网络
    protected boolean isNetworkConnected(Context context) {
        if (context != null) {
            ConnectivityManager mConnectivityManager = (ConnectivityManager) context
                    .getSystemService(Context.CONNECTIVITY_SERVICE);
            NetworkInfo mNetworkInfo = mConnectivityManager.getActiveNetworkInfo();
            if (mNetworkInfo != null) {
                return mNetworkInfo.isAvailable();
            }
        }
        return false;
    }

    //判断WIFI
    public boolean isWifiConnected(Context context) {
        if (context != null) {
            ConnectivityManager mConnectivityManager = (ConnectivityManager) context
                    .getSystemService(Context.CONNECTIVITY_SERVICE);
            NetworkInfo mWiFiNetworkInfo = mConnectivityManager
                    .getNetworkInfo(ConnectivityManager.TYPE_WIFI);
            if (mWiFiNetworkInfo != null) {
                return mWiFiNetworkInfo.isAvailable();
            }
        }
        return false;
    }

    //关闭网络判断
    protected void stopNetworkService() {

        if (network != null) {
            stopService(network);
        }
    }

    protected void ShowToast(Context context,String str){
        Toast.makeText(context,str,Toast.LENGTH_SHORT).show();
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        LogUtils.d("---->BaseActivity onDestroy stopNetworkService");
        stopNetworkService();
    }
}

這樣的一個類，在我之前的項目中有出現類似的，主要是方便開發

    }

        timer.schedule(task, 1000, 1000);
    }

    @Override

        super.onDestroy();

        } else {
            Intent intent = null;
            // 先判断当前系统版本
            if (android.os.Build.VERSION.SDK_INT > 10) {  // 3.0以上
                intent = new Intent(android.provider.Settings.ACTION_WIRELESS_SETTINGS);
            } else {
                intent = new Intent();
                intent.setClassName("com.android.settings", "com.android.settings.WirelessSettings");
            }
            startActivity(intent);

    }

這邊的.interpolate(new AccelerateDecelerateInterpolator()) .withListener(new Animator.AnimatorListener()可以不調用，看你具體業務需求了

            }
        }

        return true;
    }
}

這邊用SharedPreferences 作為本地化的一些操作（因為會加一個記住密碼這樣的東西，數據庫啊SD卡都行，看你喜歡了 SP方便點。 但是記得加密啊！！）

頁面跳轉類（現有的代碼裏也有一Intent方可以加到裏面來，之後再做優化吧）

public class PageSwitch {

    public static void goToLoginActivity(Activity activity) {
        Intent intent=new Intent(activity,LoginActivity.class);
        activity.startActivity(intent);
    }

    public static void goToRegisterActivity(Activity activity) {
        Intent intent=new Intent(activity,RegisterActivity.class);
        activity.startActivity(intent);
    }

}
