<content type="html"><![CDATA[<h4 id="广播接收"><a href="#广播接收" class="headerlink" title="广播接收"></a>广播接收</h4><p><img src="http://upload-images.jianshu.io/upload_images/1747785-f5cde23a83fee62a.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240" alt="img"><br><img src="http://upload-images.jianshu.io/upload_images/1747785-a9134c95974ad0f6.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240" alt="img"></p>
<ul>
<li>动态注册 <ul>
<li>创建一个类继承与BroadcastReceiver ,重写onReceiver()方法</li>
<li>在想要接收广播的地方注册广播,并销毁广播</li>
<li>只有在Action和在IntetnFilter对象中添加的Action的值完全吻合的时候才会促发广播接收者的onReceiver()方法</li>
<li>动态注册依赖与App的某一组件,只有的当那个组件启动的时候才会注册广播,所以说有一定的局限性</li>
</ul>
</li>
</ul>
<p><img src="http://upload-images.jianshu.io/upload_images/1747785-5e497fe427422cf7.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240" alt="img"></p>
<ul>
<li>静态注册<ul>
<li>静态注册是以xml的形式注册到manifest.xml 文件中</li>
<li>并在该Receiver中添加IntentFilter的各种参数,比如上图中的开机广播</li>
</ul>
</li>
</ul>
<h4 id="自定义广播"><a href="#自定义广播" class="headerlink" title="自定义广播"></a>自定义广播</h4><p><img src="http://upload-images.jianshu.io/upload_images/1747785-3afe92f14d16ccaf.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240" alt="img"><br><img src="http://upload-images.jianshu.io/upload_images/1747785-2f1f6ee588acfe48.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240" alt="img"></p>
<ul>
<li>创建广播接收器 </li>
<li>创建自定义的action</li>
<li>创建Intent intent=new Intent(“自定义action”)</li>
<li>在调用Context的sendBroadcast(intent)</li>
<li><p>通过这种方式创建的自定义广播是标准的广播,也就是说当广播接收器接收到广播的时机不分先后,而且都会收到</p>
</li>
<li><p>发送有序广播</p>
<ul>
<li>将发送广播的sendBroadcast()方法替换为sendOrderedBroadcast(intent ,null);</li>
<li>当发送有序广播时候,就可以在广播接收器中设置官博接收器的优先级,和调用abortBroadcast()来拦截广播</li>
</ul>
</li>
</ul>
<h4 id="使用本地广播"><a href="#使用本地广播" class="headerlink" title="使用本地广播"></a>使用本地广播</h4><p><img src="http://upload-images.jianshu.io/upload_images/1747785-7fab1cf4c60a2b1d.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240" alt="img"></p>
<ul>
<li>使用本地广播可以有效的避免安全问题,使用本地广播发送出的广播,只有在本应用内才能收到</li>
<li>只需要将通过LocaBroadcastManager.getInstance()获取一个LocalBroadcast的实例,</li>
<li>以后不管是发送广播还是注册广播接收器都使用该实例对象,就可使用本地广播</li>
</ul>
<h4 id="广播的最佳实践"><a href="#广播的最佳实践" class="headerlink" title="广播的最佳实践"></a>广播的最佳实践</h4><ul>
<li><p>实现强制下线功能</p>
</li>
<li><p>分析: 不管在任何界面都要实现随时的下线功能,不可能所有的类中都要重新注册广播接收器,所以最好的方法就是在定义在基类中</p>
</li>
<li>强制下线相当与是关闭所有界面,即Activity,所以也在基类中创建一个Activity的管理类在要下线的时候一次性关闭所有的Activity</li>
<li>要想在界面上弹出一个Dialog,就只能是动态注册广播</li>
<li>因为要保证只有处于栈顶的Activity才能接收到这条强制下线的广播,所以在基类的onResume()注册广播,在onPause()中取消注册</li>

<content type="html"><![CDATA[<h2 id="Android-数据持久化"><a href="#Android-数据持久化" class="headerlink" title="Android 数据持久化"></a>Android 数据持久化</h2><p>@第一行代码</p>
<h4 id="数据持久化简介"><a href="#数据持久化简介" class="headerlink" title="数据持久化简介"></a>数据持久化简介</h4><ul>
<li>数据持久化就是就将手机或是电脑中的临时数据(瞬时数据)保存到存储设备中,即使设备断电,或者关机的情况下,这些数据任然不会丢失.</li>
</ul>
<h4 id="文件"><a href="#文件" class="headerlink" title="文件"></a>文件</h4><ul>
<li>文件存储是数据持久化的最基本的一种数据存储方式,,他不对存储的内容进行任何格式化处理.所有的数据都是原封不动的保存到文件中,适合存储一些简单的文本数据和二进制数据.</li>
</ul>
<ul>
<li>文件读写<ul>
<li>write</li>
<li><img src="http://om4pdatog.bkt.clouddn.com/File_save.png" alt="img"><ul>
<li>首先根据Context类中的一个openFileOutput()方法,把要保存的的数据存到文件中,参数一是文件名,参数二是文件的操作模式</li>
<li>主要有两种操作模式,MODE_PRICATE 和 MODE_APPEND,</li>
<li>其中MODE_PRICATE 是默认的操作模式, 表示文件名存在的时候就会覆盖之前存储的数据</li>
<li>MODE_APPEND 表示文件存在的时候就会,继续往该文件中追加内容</li>
<li>openFileOutput()会返回一个FileOutputStream 对象,剩下的就是JAVA对流的操作将数据写到文件中</li>
<li>保存好的文件默认会保存在data/data/包名/files/目录中</li>
</ul>
</li>
<li>read</li>
<li><img src="http://om4pdatog.bkt.clouddn.com/File_read.png" alt="img"></li>
</ul>
</li>
</ul>
<h4 id="SharedPreferences"><a href="#SharedPreferences" class="headerlink" title="SharedPreferences"></a>SharedPreferences</h4><ul>
<li><p>不同于文件存储,SharedPreferences 保存的数据使用的键值对的形式.也就是说在保存一条数据的时候就要为这条数据添加一个Key,在获取这条数据的时候也是根据这个key来获取值,而且SharedPreferences 还支持不同的数据类型,保存为int类型,取出来的就是int类型,保存为String类型,取出来的时候就是Stirng类型</p>
</li>
<li><p>获取SharedPreferences 实例</p>
<ul>
<li>Context 类中的getSharedPreferences(),第一个参数是SharedPreferences的文件名,参数二是操作模式,目前只有MODE_PRICATE 这一种模式可选</li>
<li>Activity类中的getPreferences(),只有一个参数,操作模式,获取的SharedPreferences文件名为当前活动的类名.</li>
<li>PreferencesManager 类中的getDefaultSharedPreferences() ,这时一个静态方法,接收一个Context参数,并自动使用当前的包名前缀来命名SharedPreferences文件</li>
</ul>
</li>
<li><p>在获取SharedPreferences 对象之后就可以向SharedPreferences 来提交数据了,提交数据一般有三个步骤</p>
<ul>
<li>调用SharedPreferences 的Edit(),获取SharedPreferences.Editor对象</li>
<li>向SharedPrefercens.Editor 对象添加数据 edit.putString();</li>
<li>将数据提交 edit.apply();</li>
</ul>
</li>
<li><p>ShreadPreferences 保存的文件默认会在data/data/包名/shared_prefs/目录下</p>
</li>
</ul>
<h4 id="SQLite"><a href="#SQLite" class="headerlink" title="SQLite"></a>SQLite</h4><ul>
<li>创建数据库<ul>
<li>创建类集成SQLiteOpenHelper,重写onCreate()和onUpgrade()</li>
<li>构造方法的四个参数 ,参数一为Context,参数二为数据库名称,第三个参数为自定义的Cursor对象,在这里一般传入null,参数四为当前数据的版本,都是整数,一般开始都为1</li>
<li>在onCreate() 通过SQLiteDatabase 对象调用execSQL(“这里传入建表的SQL语句”)</li>
<li>在创建数据库的时候一般是通过获取SQLiteOpenHelper对象,然后掉用getReadableDatabse()就会执行创建数据库的操作</li>
<li>如果在创建数据库的时候检测到数据库已经存在就不会再执行创建数据库的操作</li>
</ul>
</li>
<li>升级数据库<ul>
<li>在升级数据在数据库的版本上要+1;当出现无法创建数据库的时候可以在onUpgrade()方法中执行</li>
<li>先将之前的数据库删掉; db.execSQL(“ drop table id exists TBALE_NAME”)</li>
<li>然后再次调用onCreate() 创建数据库</li>
</ul>
</li>
<li><p>添加数据</p>
<ul>
<li>在SQLite 中执行CRUD 的操作都是在SQLiteDatabase 对象的基础上操作的</li>
<li>添加是调用SQLiteDatabase 对象的 insert(),这里有三个参数</li>
<li>参数一是:表名,参数二是:在未指定添加数据情况下给某些可能为空的列自动赋值null,一般我们用不到,在这里一般传入NULL,参数三是ContentValue对象,他通过一系列重载的方法,可以传入不同类型的数据</li>
</ul>
</li>
<li><p>更新数据</p>
<ul>
<li>SQLiteDatabase 对象调用update() </li>
<li>参数一:表名 参数二:ContentValue对象,参数三和参数四用于约束某一行或者某几行中的数据,不指定的话就是默认更新所有行</li>
</ul>
</li>
<li><p>删除数据</p>
<ul>
<li>SQLiteDatabase 对象调用delete()</li>
<li>三个参数;参数一是表名,参数二和参数三还是用于约束</li>
</ul>
</li>
<li>查询数据<ul>
<li>SQLiteDatabase 对象调用query() ,这个方法有最少的也是有七个参数</li>
<li>参数一: 固定不变还是表名 </li>
<li>参数二: 查询列名</li>
<li>参数三: 约束条件</li>
<li>参数四: 占位符对应的值</li>
<li>参数五: 需要排序的列</li>
<li>参数六: 排序约束</li>
<li>参数七: 制定查询结果的排序</li>
<li>不指定参数默认查询所有数据</li>
</ul>
</li>
<li>使用传统的SQL操作数据库<ul>
<li>添加,删除,修改 execSQL(“SQL”)</li>
<li>查询 , rawQuery(“SQL”)</li>
</ul>
</li>
</ul>
<h4 id="使用开源项目-LitePal"><a href="#使用开源项目-LitePal" class="headerlink" title="使用开源项目 LitePal"></a>使用开源项目 LitePal</h4><ul>
<li>LItePal简介<ul>
<li>LItePal 是一个开源的Android数据库框架,它采用的是对象关系映射(ORM)的模式,它将我们平时开发用到的一些常用功能进行了封装,不用编写一行SQL语句就可以完成建表和各种增删改查的操作.</li>
</ul>
</li>
<li>配置LitePal<ul>
<li>添加依赖 comple ‘org.litepal.android:core:1.4.1’</li>
<li>在main文件夹下创建 asstes 文件夹, 并创建litepal.xml 文件夹<ul>
<li><img src="http://om4pdatog.bkt.clouddn.com/litepal.png" alt="img"> </li>
<li>dbname 表示数据库的名称</li>
<li>version 表示数据库版本</li>
<li>list 表示用于指定所有的映射模型</li>
</ul>
</li>
<li>manifest.xml 配置application 节点 name属性值为 org.litepal.LitePalApplication</li>
</ul>
</li>
</ul>
<ul>
<li>创建和升级数据库<ul>
<li>创建一个Javabean 类,把这个类的完整类名添加到litepal.xml 中的lsit 标签中的 <mapping> </li>
<li>创建数据的时候只需要调用 <code>LitePal.getDatabase();</code> 就可已完成数据的创建.</li>
<li>升级数据库 只需要修改两个地方<ul>
<li>第一在litepal.xml 修改你的数据库版本号</li>
<li>第二,如果有新建的bean类,还需要把它的全名添加到litepal.xml 文件的list 标签中.</li>
</ul>
</li>
</ul>
</li>
<li>添加数据<ul>
<li>添加数据的方法和在Java中对对象的操作是一样的</li>
<li>创建Bean 类对象</li>
<li>调用对象的set…()方法</li>
<li>在完成数据的添加之后调用对象save() 方法 就可以完成添加数据的操作 </li>
</ul>
</li>
<li>更新数据<ul>
<li>对已经存储的对象操作<ul>
<li>对与已经存在的对象进行操作 可以直接对象调用set方法,然后调用save()</li>
</ul>
</li>
<li>如果当前对象是第一次创建的话可以使用 updateAll() 方法进行跟新数据,方法内的参数也是用于条件约束的,但是此方法不可以为参数设置默认值,如果为参数设置默认值,那么litepal 是不会对这个参数进行更新操作</li>
<li>对于想要设置默认参数的操作LitePal 提供了一个setToDefaule()方法 只要在方法内传入想要修改的字段名(列名)就可以</li>
</ul>
</li>
<li>删除数据<ul>
<li>通过DataSupport.deleteAll()方法</li>
<li>第一个参数表示要删出哪一张表的的数据 ,参数的值类的字节码对象</li>
<li>后面两个参数表示指定的约束条件</li>
</ul>
</li>
<li>查询数据<ul>
<li>使用DataSupport.findAll(), 只需要输入要查询的类的字节码即可查询这个表中的所有数据</li>
<li>查询第一条 DataSupport.findFirst()</li>
<li>查询最后一条 DataSuppprt.findLast();</li>
<li>也可以使用连缀查询<ul>
<li>DataSupport.select(“name”,”author”).find(Book.class); 查询book表中name和author的这两列的数据</li>
<li>DataSupport.where(“pages>?”, 100).fins(“Book.class”); 查询book表中页数大于400的数据</li>
<li>DataSupport.order(“price desc”).find(“Book.class”); 查询Book表所有的数据,并按照书价从高到低排序</li>
<li>DataSupport.limit(3).find(“Book.class”); 查询表中的前三条数据</li>
<li>DataSupport.limit(3).offset(1).find(“Book.class”);查询表中的2.3.4条数据 offset 用于设置偏移量</li>
<li>DataSupport.select(“”name,”price”,”pages”).where(“pages>?”,100).order(“pages”).limit(10).offset(10).find(“Book.class”);这条徒具表示的是查询Book表中第10-20条满足pages大于100这个条件的name,price,pages三列的数据,并将最后的数据按照pages升序排列</li>

<content type="html"><![CDATA[<h2 id="Android-中引入百分比布局"><a href="#Android-中引入百分比布局" class="headerlink" title="Android 中引入百分比布局"></a>Android 中引入百分比布局</h2><ul>
<li>一直以来,由于Android设备的多样性,要想达到在不同设备上尽可能的显示相同的效果.屏幕适配也是开发者不得考虑的一件事</li>
<li>在以前适配的方案无非是 <ul>
<li>禁用绝对布局</li>
<li>使用相对布局</li>
<li>使用线性布局,使用权重属性</li>
<li>在者就是根据不同分辨率创建不同的dimens文件</li>
<li>针对图片适配的话尽可能的使用.9图</li>
</ul>
</li>
<li>现在Android引入了一中全新的布局方式来解决这个问题—百分比布局,这种布局不再使用以前warp-content,mtach-parent这种方式来指定控件的大小,而是可以直接指定控件在布局中所占的百分比,这样的话就可以实现平分布局或者是任意比例分割布局的效果了.</li>
<li>由于LinearLayout 已经支持按比例分布控件,所以百分比布局只为FramLayout和RelativeLayout这两个控件进行了拓展,提供了PercentFramlayout 和PercentRelativeLayout</li>
<li>由于百分比布局是新增布局,所以在使用的时候需要先在build.gradle添加 百分比布局的依赖,他就在support包下</li>
</ul>
<pre><code><figure class="highlight plain"><figcaption><span>'com.android.support:percent:24.2.1' </span></figcaption><table><tr><td class="gutter"><pre><div class="line">1</div></pre></td><td class="code"><pre><div class="line"> </div></pre></td></tr></table></figure>
</code></pre><ul>
<li>在使用的时候就和平常的布局一样,在他布局被的控件就可以使用layout_widthPercent layout_heightPercent 这来两个属性开控制控件在布局中所占的百分比了</li>
</ul>

<content type="html"><![CDATA[<h2 id="探究Activity"><a href="#探究Activity" class="headerlink" title="探究Activity"></a>探究Activity</h2><h4 id="Activity的基本使用"><a href="#Activity的基本使用" class="headerlink" title="Activity的基本使用"></a>Activity的基本使用</h4><ul>
<li>1.手动创建Activity<ul>
<li>自定义class继承 appCompatActivity或是其他Activity类</li>
<li>通过setContentView(“布局”)为Activity添加布局文件</li>
<li>在AndroidManifest.xml 注册改 Activity</li>
</ul>
</li>
<li>2.在Activity中使用Toast<ul>
<li>Toast.makeText(“上下文,Context的子类”,”显示的字符串”,Toast.LENGTH_SHORT).show(); </li>
</ul>
</li>
<li>3.在Activity中使用Menu<ul>
<li>创建item菜单</li>
<li>在Activity中重写onCreateOptionsMenu(Menu menu),加载资源文件到menu上,当返回值为true 的时候 menu 才会显示 </li>
</ul>
</li>
<li>4.销毁Activity<ul>
<li>Activity中调用 finish() 销毁当前的Activity </li>
</ul>
</li>
</ul>
<h4 id="Intent的使用"><a href="#Intent的使用" class="headerlink" title="Intent的使用"></a>Intent的使用</h4><ul>
<li>显式Intent<ul>
<li>显式Intent ,顾名思义 是指确切的知道将要打开的Activity,</li>
<li>使用方式,new Intent(Context, NextActivity.class); </li>
</ul>
</li>
<li>隐式Intent<ul>
<li>隐式Intent ,是指在没有确定知道要跳转的Activity,使用了一系列的action,category,由系统去分析这个Intent,找到合适的Activity并启动</li>
<li>在activtiy指定了action 或是categroy 时,启动Activity的Intent必须都与该Activity参数都一一对应时候才会启动该Activity</li>
<li>category 的默认参数一般不用写,也可以启动</li>
<li>比如启动系统浏览器打开百度<ul>
<li>Intent intent=new Intent(Intent.ACTION.VIEW);</li>
<li>intetn.setData(Uri.parse(“<a href="http://www.baidu.com" target="_blank" rel="external">http://www.baidu.com</a>“))</li>
<li>staetActivity(intent);</li>
</ul>
</li>
<li>比如启动打电话<ul>
<li>Intent intent=new Intent(Intent.ACTION.DLAL);</li>
<li>intent.setData(Uri.parse(“tel:10086”));</li>
<li>startActivity(intent); </li>
</ul>
</li>
</ul>
</li>
<li>向下一个Activity传递参数<ul>
<li>传递参数可使用intent.putExtra(“KEY”,”value”)</li>
<li>该方法重载,可以传递多种数据类型</li>
<li>可以使用传递Bundle对象</li>
<li>要想传递其他的对象类型的参数的时候,该类必须实现Serializable 或者 Parcelable</li>
<li>在启动的Activity 中通过 getIntent() 获取Intent对象<ul>
<li>在通过intent对象,获取传递过来的参数,比如传递额String类型的参数,就通过intent.getStringExtra(“KEY”)</li>
<li>传递的整数,就通过intent.getIntExtra(“KEY”); </li>
</ul>
</li>
</ul>
</li>
<li>返回数据给上一个Activity<ul>
<li>在返回给上一个Activity参数中用到的是一个requesCode 和一个 resultCode</li>
<li>requestCode用于标记是从哪个Activiyt启动的</li>
<li>resultCode用于标记是从哪个Activity返回的</li>
<li>在需要返回个上一个Activty数据这种情况的时候,启动Activity的方式就不是原来的startActivity(intent)了</li>
<li>具体使用<ul>
<li>ActivityOne startActivitForResutl(intent,requestCode) requestCode 随意指定,但一定要唯一</li>
<li>ActivityTwo setResult( resultCode ,intent); finish; resultCode 随意指定,但一定要唯一</li>
<li>当ActivityTwo 销毁的时候就会调用ActivityOne 中的onActivityResult(int requestCode,int resultCode,Intent data)</li>
<li>在判断requestCode 和 resultCode 都准确无误的情况下,就可以使用date.getStringExtra(“KEY”),获取返回的数据</li>
</ul>
</li>
</ul>
</li>
</ul>
<h4 id="Activity-的生命周期"><a href="#Activity-的生命周期" class="headerlink" title="Activity 的生命周期"></a>Activity 的生命周期</h4><ul>
<li>完整的生命周期<ul>
<li>onCreate() > onStart() > onResume > onPause() > onStop() > onDestroy()</li>
<li>onRestatrt();</li>
</ul>
</li>
<li>不同状态下的方法回调<ul>
<li>启动ActivityOne onCreate() > onStart() > onResume();</li>
<li>在ActivityOne 中启动 ActivityTwo ActivityOne 中会调用 onPause() > onStop() </li>
<li>从ActivityTwo 中返回 ActivityOne ActivityOne中会调用onRestart() > onStart() > onResume();</li>
<li>在ActivtiyOne中按下返回键时 ActivityOne 中会调用onPause() > onStop() > onDestroy();</li>
<li>如果在新打开的Activity没有完全的遮挡住下面的Activity的时候, 下面的Activity只会回调 onPause(),还是属于可见的状态,再次返回的时候也只是会回调onResume()</li>
</ul>
</li>
<li>Activity的被销毁时的数据存储<ul>
<li>当手机的内存不足的情况下,会销毁处于停止状态的Activity.为了优化用户体验, 所以这时数据的保存就显得尤为重要.</li>
<li>在Activity销毁的时候必然会调用onSaveInstaceState(Bundle outState),可以通过bundle 以键值对的形式传递参数,</li>
<li>当Activity再次重新创建的时候调用的onCreate(Bundle onSaveInstaceState) 取出Bundle所携带的参数</li>
<li>因为第一次创建Activity的时候没有返回的参数,所以要在这里判断Bundle是否为null之后在进行下一步操作</li>
</ul>
</li>
</ul>
<h4 id="Activity-的启动模式"><a href="#Activity-的启动模式" class="headerlink" title="Activity 的启动模式"></a>Activity 的启动模式</h4><ul>
<li>standard 每一Activity 默认的启动模式,是以先进后出的结构进行,每次打开一个新的Activity都会重新创建</li>
<li>singleTop 单栈顶模式,在启动一个Activity时候判断是否在栈顶,如果不再栈顶,就会重新创建一个新的Activity实例,如果在栈顶,就会复用该栈顶的Activity 实例.</li>
<li>singleTask 单任务栈模式, 再打开一个新的Activity的时候会判断该Activity是否在该任务栈存在,如果存在,就选择复用,不存在就会新创建一个Activity的实例</li>
<li>singleInstance 单独的返回栈管理一个Activity </li>
</ul>
<h4 id="Activity-的最佳实践"><a href="#Activity-的最佳实践" class="headerlink" title="Activity 的最佳实践"></a>Activity 的最佳实践</h4><ul>
<li>知晓当前在那个Activity<ul>
<li>创建BaseActivity 在onCreate()中调用getClass().getSimpleName(), 让所有的Activity都继承BaseActivity</li>
</ul>
</li>
<li>安全的退出Activity<ul>
<li>创建ActivtiController . 添加addActivity(Activity activity) 并在BaseActivity 的onCreate() 中调用</li>
<li>添加removeActivity(Activity activity) 在BaseActivity的onDestroy()中调用</li>
<li>创建finishAllActivity() 在需要关闭所有Activity的地方调用即可</li>
</ul>
</li>
<li>启动Activity的最佳写法<ul>
<li>将打开Activity所需要用到的参数,以方法的形式封装,只把需要用到的参数对外暴露,简单,明了</li>
</ul>
</li>
</ul>

<content type="html"><![CDATA[<h2 id="Android-menu-使用"><a href="#Android-menu-使用" class="headerlink" title="Android menu 使用"></a>Android menu 使用</h2><h4 id="使用步骤"><a href="#使用步骤" class="headerlink" title="使用步骤"></a>使用步骤</h4><h4 id="创建菜单项"><a href="#创建菜单项" class="headerlink" title="创建菜单项"></a>创建菜单项</h4><p><img src="http://om4pdatog.bkt.clouddn.com/menu_path.png" alt="img"><br><img src="http://om4pdatog.bkt.clouddn.com/menu_item.png" alt="img"></p>
<p>1.在res文件夹下创建menu文件夹,用与存放xml文件,然后在menu 文件夹中创建menu.xml文件,编写menu文件<br> 2.menu.xml , 一个item就表示一个菜单项,每一个item 必不可少的就是id(唯一标识服)和title(item 名称)</p>
<h4 id="重写onCreateOptionsMenu-Menu-menu-创建菜单"><a href="#重写onCreateOptionsMenu-Menu-menu-创建菜单" class="headerlink" title="重写onCreateOptionsMenu(Menu menu) 创建菜单"></a>重写onCreateOptionsMenu(Menu menu) 创建菜单</h4><p><img src="http://om4pdatog.bkt.clouddn.com/createOptionsMenu.png" alt="img"></p>
<p>1.使用getMenuInflater() 获取MenuInflater 对象,通过inflate(@MenuRes int menuRes, Menu menu)就可以创建菜单了,inflate接受两个参数,第一个参数标识我们通过那个资源文件来创建文件,第二个参数表示我们常见出来的菜单项将添加到哪个menu对象上.</p>
<h4 id="重写onOptionsitemSelected-MenuItem-item-实现菜单项的点击事件"><a href="#重写onOptionsitemSelected-MenuItem-item-实现菜单项的点击事件" class="headerlink" title="重写onOptionsitemSelected(MenuItem item) 实现菜单项的点击事件"></a>重写onOptionsitemSelected(MenuItem item) 实现菜单项的点击事件</h4><p><img src="http://om4pdatog.bkt.clouddn.com/OptionsItemSelected.png" alt="img"></p>
<p>通过item.getItemId()即可获取到item项的资源ID,通过对比资源ID,即可进行后续操作</p>
