DrawerLayout實(shí)現(xiàn)網(wǎng)易新聞抽屜效果

1、個人感覺網(wǎng)易的客戶端比擬前衛(wèi)，有很多新鮮的東西，有時候模仿這些好的客戶端 能學(xué)到很多東西開始今天的主要課題，下面是網(wǎng)易客戶端抽屜模式實(shí)現(xiàn)的效果openDrawer(toOpen);break;case LOCK_MODE_LOCKEDCLOSED:final View toClose = findDrawerWithGravity(absGravity);if (toClose != null) closeDrawer(toClose);break;/ default: do nothing)啟用或禁用了所有的抽屜互動。其實(shí)有個Drawerlayout這個布局，你得問題就已經(jīng)解決掉一大半了,D

2、rawerlayout布局本身就提供了左劃和右劃的功能先上代碼,然后慢慢解答，看完這篇博客你就知道Drawerlayout怎么用了首先上逐步局文件代碼Drawerlayout是Androidv4包里自帶的，既然是自帶的那么直接拿來用就可以 了，當(dāng)然前提是你得工程里有v4包下面解釋上面的布局文件，讓你懂得Drawerlayout用法，首先Drawerlayout支 持左劃和右劃，那他是如何控制的呢?不居中告訴你，以上布局分為三局部,一般情 況下，第一局部是主步局，第二局部是左劃的布局，第三局部是右劃的布局,其實(shí)這 里的左向滑動和右向滑動是通過gravity控制，左劃界面android:layou

3、t_gravity=left當(dāng)然這里的left也可以用start代替，右劃界面 就理所當(dāng)然的是 android:layout_gravity=rightright 也可以用 end 代替，其余的應(yīng)該明白了吧!不懂留言，我認(rèn)真為你解答下面在貼一下主界面的代碼，你看懂Drawerlayout用法其余的就很簡單了，媽媽 再也不懂擔(dān)憂你的學(xué)習(xí)了package com. sdufe. thea. guo;import java. util.

12、awer motion state changes. The new state willbe one of link #STATE_IDLE, link #STATE_DRAGGING or link #ST ATE_SETTLING.*param newState The new drawer motion state*/public void onDrawerStateChanged(int newState);上面主要是監(jiān)聽事件的接口，通常回調(diào)的時候回用到它，里面的方法有四個，分別是 onDrawerSlide(View drawerView, floatslideOffset);on

13、DrawerOpened(View drawerView);onDrawerClosed(ViewdrawerView);onDrawerStateChanged(int newState);onDrawerSlide(View drawerView, float slideOffset)抽屜改變時使用onDrawerOpened(View drawerView)才了開抽屜onDrawerClosed(View drawerView)關(guān)閉抽屜onDrawerStateChanged(int newState);改變抽屜的狀態(tài)/*Set a simple drawable used for th
