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

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

整個程序的主介面 Main

public class Main extends BaseActivity {
         final static String TAG = Main.class.getName() + ".TAG";    private final static boolean DEBUG = true;    private ImageView imageView;    private YoYo.YoYoString rope;    //計時器    private int recLen = 5;    Timer timer = new Timer();    TimerTask task = new TimerTask() {        public void run() {            recLen--;            //修改界面的相关设置只能在UI线程中执行            runOnUiThread(new Runnable() {                public void run() {                    if (recLen < 3) {                        timer.cancel();                        goToNext();                    }                }            });        }    };    @Override    protected void findById() {        imageView = (ImageView) findViewById(R.id.imageView);    }    @Override    protected void setListener() {    }    @Override    protected void logic() {        //漸漸放大        rope = YoYo.with(Techniques.ZoomInUp).duration(1800).playOn(imageView);        timer.schedule(task, 1000, 1000);    }    @Override    protected int getLayout() {        return R.layout.main;    }    @Override    protected void onDestroy() {        super.onDestroy();        LogUtils.d("---->Main onDestroy stopNetworkService");        stopNetworkService();    }    private void goToNext() {        if (isNetworkConnected(Main.this)) {            SharedPreferences sharedPreferences = getSharedPreferences("userinfo", Activity.MODE_PRIVATE);            String name=sharedPreferences.getString("username", "");            Intent a;            if(name.equals(null) || name.length() <= 0){                a = new Intent(Main.this, RegisterActivity.class);            }else{                a = new Intent(Main.this, LoginActivity.class);            }            startActivity(a);            overridePendingTransition(R.anim.scale_in, R.anim.alpha_out);        } 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

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);    }}

註冊的XML

登錄的XML

還有一些工具類和自定義控件就在源碼中看吧，源碼地址：記得點暫哦！！！

有什麼希望我加的也可以留言，需求方面 沒有什麼很大的頭緒，不知道要做什麼。
