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

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

hashMap.put("password", password.getText().toString());
hashMap.put("username", user.getText().toString());

localEditor.clear().commit();
return false;
}else{
localEditor.putString(key,val);
localEditor.commit();
}
}

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);
}

}

還有一些工具類和自定義控件就在源碼中看吧，源碼地址：https://github.com/ddwhan0123/TiffanyProject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。
