2017 已来，最全面试总结——这些 Android 面试题你一定需要

<h2>前言</h2> <p>来年发完年终奖。也许有不少Android程序员开始摩拳擦掌蠢蠢欲动了。结合以往自己的经历，今天给大家总结下Android面试题，希望有帮助。</p> <h3>01 Activity生命周期？</h3> <p>这几乎是个老少咸宜，永远不会过时的问题，而且极有可能是第一个问题。这个问题当然没什么好讲的啦，死记硬背是没什么用的了，关键是理解。本人就曾遇到这个问题的变种问题，问onStart(),与onResume()有什么区别？如果面试官抛出这个问题，是不是有点措手不及。今天又听说有同学遭遇了更变态的问题：什么情况下Activity走了onCreat()，而不走onStart()，这简直就是脑筋急转弯嘛。</p> <h3>02 Service生命周期？</h3> <p>这里要注意service有两种启动方式，startService()和bindService()</p> <p style="text-align:center"><img src="https://simg.open-open.com/show/c9697667fb7a56b69e672a5da164e738.jpg"></p> <h3>03 理解Activity，View,Window三者关系</h3> <p>这个问题真的很不好回答。所以这里先来个算是比较恰当的比喻来形容下它们的关系吧。Activity像一个工匠（控制单元），Window像窗户（承载模型），View像窗花（显示视图）LayoutInflater像剪刀，Xml配置像窗花图纸。</p> <p>1：Activity构造的时候会初始化一个Window，准确的说是PhoneWindow。</p> <p>2：这个PhoneWindow有一个“ViewRoot”，这个“ViewRoot”是一个View或者说ViewGroup，是最初始的根视图。</p> <p>3：“ViewRoot”通过addView方法来一个个的添加View。比如TextView，Button等</p> <p>4：这些View的事件监听，是由WindowManagerService来接受消息，并且回调Activity函数。比如onClickListener，onKeyDown等。</p> <h3>04 四种LaunchMode及其使用场景</h3> <p>standard 模式</p> <p>这是默认模式，每次激活Activity时都会创建Activity实例，并放入任务栈中。使用场景：大多数Activity。</p> <p>singleTop 模式</p> <p>如果在任务的栈顶正好存在该Activity的实例，就重用该实例( 会调用实例的 onNewIntent() )，否则就会创建新的实例并放入栈顶，即使栈中已经存在该Activity的实例，只要不在栈顶，都会创建新的实例。使用场景如新闻类或者阅读类App的内容页面。</p> <p>singleTask 模式</p> <p>如果在栈中已经有该Activity的实例，就重用该实例(会调用实例的 onNewIntent() )。重用时，会让该实例回到栈顶，因此在它上面的实例将会被移出栈。如果栈中不存在该实例，将会创建新的实例放入栈中。使用场景如浏览器的主界面。不管从多少个应用启动浏览器，只会启动主界面一次，其余情况都会走onNewIntent，并且会清空主界面上面的其他页面。</p> <p>singleInstance 模式</p> <p>在一个新栈中创建该Activity的实例，并让多个应用共享该栈中的该Activity实例。一旦该模式的Activity实例已经存在于某个栈中，任何应用再激活该Activity时都会重用该栈中的实例( 会调用实例的 onNewIntent() )。其效果相当于多个应用共享一个应用，不管谁激活该 Activity 都会进入同一个应用中。使用场景如闹铃提醒，将闹铃提醒与闹铃设置分离。singleInstance不要用于中间页面，如果用于中间页面，跳转会有问题，比如：A -> B (singleInstance) -> C，完全退出后，在此启动，首先打开的是B。</p> <h3>05 View的绘制流程</h3> <p>measure过程</p> <p>layout过程</p> <p>draw过程</p> <p><a href="http://mp.weixin.qq.com/s?__biz=MzI0MjE3OTYwMg==&mid=2649547668&idx=1&sn=b2667c46188c6674c90aa72c2fba4719&scene=21#wechat_redirect">从此再有不愁自定义View——Android自定义view详解</a></p> <p><a

<code class="language-java">public boolean dispatchTouchEvent(MotionEventev); //用来分派event public boolean onInterceptTouchEvent(MotionEventev); //用来拦截event public boolean onTouchEvent(MotionEventev); //用来处理event </code></pre> <p>其中Activity和View控件（TextView）拥有分派和处理事件方法，View容器（LinearLayout）具有分派，拦截，处理事件方法。这里也有个比喻：领导都会把任务向下分派，一旦下面的人把事情做不好，就不会再把后续的任务交给下面的人来做了，只能自己亲自做，如果自己也做不了，就只能告诉上级不能完成任务，上级又会重复他的过程。另外，领导都有权利拦截任务，对下级隐瞒该任务，而直接自己去做，如果做不成，也只能向上级报告不能完成任务。</p> <h3>07 Android中的几种动画</h3> <p>曾被问到Android中有几种动画，这个问题也好难回答。Android3.0之前有2种，3.0后有3种。</p> <p>FrameAnimation（逐帧动画）：将多张图片组合起来进行播放，类似于早期电影的工作原理，很多App的loading是采用这种方式。</p> <p>TweenAnimation（补间动画）：是对某个View进行一系列的动画的操作，包括淡入淡出（Alpha），缩放（Scale），平移（Translate），旋转（Rotate）四种模式。</p> <p>PropertyAnimation（属性动画）：属性动画不再仅仅是一种视觉效果了，而是一种不断地对值进行操作的机制，并将值赋到指定对象的指定属性上，可以是任意对象的任意属性。</p>

Android中跨进程通讯的几种方式</h3> <p>1：访问其他应用程序的Activity</p> <p>如调用系统通话应用</p> <p>Intent callIntent=new Intent(Intent.ACTION_CALL,Uri.parse("tel:12345678");</p> <p>startActivity(callIntent);</p> <p>2：Content
