ServiceTitle

android.service.quicksettings.TileService

/**

     * A TileService provides the user a tile that can be added to Quick Settings.
     * Quick Settings is a space provided that allows the user to change settings and
     * take quick actions without leaving the context of their current app.
     *
     * <p>The lifecycle of a TileService is different from some other services in
     * that it may be unbound during parts of its lifecycle.  Any of the following
     * lifecycle events can happen indepently in a separate binding/creation of the
     * service.</p>
     *TitleService的生命周期和其他Service的不一样，它会在任意一个生命阶段unbound(解绑)。生命周期中的任意一个阶段可以
     * 独立的发生在一个不同的Service 实例中。
     *
     *
     * <ul>
     * <li>When a tile is added by the user its TileService will be bound to and
     * {@link #onTileAdded()} will be called.</li>
     *当一个title被用户添加了，它的TitleService将会被绑定并回调onTileAdded()。
     *
     *
     * <li>When a tile should be up to date and listing will be indicated by
     * {@link #onStartListening()} and {@link #onStopListening()}.</li>
     *当title需要更新，列表将由onStartListening()和onStopListening()通知。
     *
     *
     * <li>When the user removes a tile from Quick Settings {@link #onTileRemoved()}
     * will be called.</li>
     * 当一个title从快速设定中移除，onTileRemoved()会被回调
     *
     * </ul>
     * <p>TileService will be detected by tiles that match the {@value #ACTION_QS_TILE}
     * and require the permission "android.permission.BIND_QUICK_SETTINGS_TILE".
     * The label and icon for the service will be used as the default label and
     * icon for the tile. Here is an example TileService declaration.</p>
     * <pre class="prettyprint">
     *     TitleService将会被识别如果匹配ACTION_QS_TILE，而且要permisson "android.permission.BIND_QUICK_SETTINGS_TILE"
     * service配置文件中的label和icon会作为快速设定中显示的标题和图标。下面是啊一个例子
     * {@literal
     * <service
     *     android:name=".MyQSTileService"
     *     android:label="@string/my_default_tile_label"
     *     android:icon="@drawable/my_default_icon_label"
     *     android:permission="android.permission.BIND_QUICK_SETTINGS_TILE">
     *     <intent-filter>
     *         <action android:name="android.service.quicksettings.action.QS_TILE" />
     *     </intent-filter>
     * </service>}
     * </pre>
     *
     * @see Tile Tile for details about the UI of a Quick Settings Tile.
