188.m1-代碼整合

代碼進行整合，ActionBar中共性的可以一起初始化，初始化界面和初始化ActionBar分別提出來,在基類中初始化共同的方法，同時在關閉的時候關閉所有的Activity并殺死行程Kill all

繼承的BaseActivity.java來繼承ActionBar

import java.util.LinkedList;
import java.util.List;

import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;

public class BaseActivity extends ActionBarActivity {

	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		//同步鎖，執行緒安全
		synchronized (mActivities) {
			// 初始化的時候往鏈表中初始化Activity，添加Activity
			mActivities.add(this);
		}

		init();
		initView();
		initActionBar();
	}

	@Override
	protected void onDestroy() {
		// 銷毀的時候remove掉
		super.onDestroy();
		synchronized (mActivities) {
			mActivities.remove(this);
		}
	}

	// 退出的時候關閉所有的Activity
	public void killAll() {
		// 復制了一份mActivities 集合
		List<BaseActivity> copy;
		
		//同步鎖，執行緒安全
		synchronized (mActivities) {
			copy = new LinkedList<BaseActivity>(mActivities);
		}
		for (BaseActivity activity : copy) {
			activity.finish();
		}
		// 殺死當前的行程
		android.os.Process.killProcess(android.os.Process.myPid());
	}

	protected void initActionBar() {
		// TODO Auto-generated method stub

	}

	protected void initView() {
		// TODO Auto-generated method stub

	}

	protected void init() {
		// TODO Auto-generated method stub

	}
