        KeyguardManager km= (KeyguardManager) context.getSystemService(Context.KEYGUARD_SERVICE); 
        KeyguardManager.KeyguardLock kl = km.newKeyguardLock("unLock"); 
        //解鎖 
        kl.disableKeyguard(); 
        //獲取電源管理器對象 
        PowerManager pm=(PowerManager) context.getSystemService(Context.POWER_SERVICE); 
        //獲取PowerManager.WakeLock對象,後面的參數|表示同時傳入兩個值,最後的是LogCat裏用的Tag 
        PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.SCREEN_DIM_WAKE_LOCK,"bright"); 
        //點亮屏幕 
        wl.acquire(); 
        //釋放

        default:
            returnConstants.NETWORK_CLASS_UNKNOWN;
        }
    }

判斷當前手機的網絡類型(WIFI還是2,3,4G)

需要用到上面的方法

public static int getNetWorkStatus(Context context) {
        intnetWorkType = Constants.NETWORK_CLASS_UNKNOWN;
 
        ConnectivityManager connectivityManager = (ConnectivityManager) context
                .getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
 
        if(networkInfo !=null&& networkInfo.isConnected()) {
            inttype = networkInfo.getType();
 
            if(type == ConnectivityManager.TYPE_WIFI) {
                netWorkType = Constants.NETWORK_WIFI;
            }elseif(type == ConnectivityManager.TYPE_MOBILE) {
                netWorkType = getNetWorkClass(context);
            }
        }
 
        returnnetWorkType;
    }

     /**
     *  px to sp
     */

public static int px2sp(Context context,floatpxValue) { finalfloatfontScale = context.getResources().getDisplayMetrics().scaledDensity; return(int) (pxValue / fontScale +0.5f); }

     /**

public static int sp2px(Context context,floatspValue) { finalfloatfontScale = context.getResources().getDisplayMetrics().scaledDensity; return(int) (spValue * fontScale +0.5f); }

把一個毫秒數轉化成時間字符串

把一個毫秒數轉化成時間字符串。格式爲小時/分/秒/毫秒（如：24903600 –> 06小時55分03秒600毫秒）

把一個毫秒數轉化成時間字符串。格式爲小時/分（如：24903600 –> 06小時55分鐘）

     * @param millis
     *            要轉化的毫秒數。

     * @param isFormat
     *            時間數字是否要格式化，如果true：少位數前面補全；如果false：少位數前面不補全。
     * @return 返回時間字符串：小時/分/秒/毫秒的格式（如：24903600 --> 06小時55分鐘）。

轉換當前時間爲易用時間格式

1小時內用，多少分鐘前； 超過1小時，顯示時間而無日期； 如果是昨天，則顯示昨天 超過昨天再顯示日期； 超過1年再顯示年。

public static long oneHourMillis =60*60*1000;// 一小時的毫秒數
public static long oneDayMillis =24* oneHourMillis;// 一天的毫秒數
public static long oneYearMillis =365* oneDayMillis;// 一年的毫秒數
 
public static String millisToLifeString(longmillis) {
        longnow = System.currentTimeMillis();
        longtodayStart = string2Millis(millisToStringDate(now,"yyyy-MM-dd"),
                "yyyy-MM-dd");
 
        // 一小時內
        if(now - millis <= oneHourMillis && now - millis > 0l) {
            String m = millisToStringShort(now - millis,false,false);
            return"".equals(m) ?"1分鐘內": m + "前";
        }
 
         // 大於今天開始開始值，小於今天開始值加一天（即今天結束值）
        if(millis >= todayStart && millis <= oneDayMillis + todayStart) {
            return"今天 "+ millisToStringDate(millis,"HH:mm");
        }
 
         // 大於（今天開始值減一天，即昨天開始值）
        if(millis > todayStart - oneDayMillis) {

字符串解析成毫秒數
