Android代碼最佳化----Application節點的模板寫法

建立一個類MyApplication，繼承自Application。代碼如下：

MyApplication.java:

 1 package com.smyhvae.homepicdemo; 2  3 import android.app.Application; 4 import android.os.Handler; 5 import android.os.Looper; 6  7 /** 8  * Created by smyhvae on 2015/5/13. 9  */10 public class MyApplication extends Application {11     //擷取到主線程的上下文12     private static MyApplication mContext = null;13     //擷取到主線程的handler14     private static Handler mMainThreadHandler = null;15     //擷取到主線程的looper16     private static Looper mMainThreadLooper = null;17     //擷取到主線程18     private static Thread mMainThead = null;19     //擷取到主線程的id20     private static int mMainTheadId;21 22     @Override23     public void onCreate() {24         // TODO Auto-generated method stub25         super.onCreate();26         this.mContext = this;27         this.mMainThreadHandler = new Handler();28         this.mMainThreadLooper = getMainLooper();29         this.mMainThead = Thread.currentThread();30         //android.os.Process.myUid()   擷取到使用者id31         //android.os.Process.myPid()擷取到進程id32         //android.os.Process.myTid()擷取到調用線程的id33         this.mMainTheadId = android.os.Process.myTid();34     }35 36     public static MyApplication getApplication() {37         return mContext;38     }39 40     public static Handler getMainThreadHandler() {41         return mMainThreadHandler;42     }43 44     public static Looper getMainThreadLooper() {45         return mMainThreadLooper;46     }47 48     public static Thread getMainThread() {49         return mMainThead;50     }51 52     public static int getMainThreadId() {53         return mMainTheadId;54     }55 56 }

 

然後記得在資訊清單檔中進行聲明：

1     <application2         android:allowBackup="true"3         android:icon="@mipmap/ic_launcher"4         android:label="@string/app_name"5         android:theme="@style/AppTheme" 6         android:name=".MyApplication">

需要聲明的是上方代碼的第6行android:name的屬性。
