Android源码分析(十三)----SystemUI下拉状态栏如何添加快捷开关
一:如何添加快捷开关
源码路径:frameworks/base/packages/SystemUI/res/values/config.xml
添加headset快捷开关,参考如下修改。

Android版本7.1修改方式
源码路径:frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/QSTileHost.java
创建HeadsetTile
对象,实现快捷开关主要功能。

Android8.0修改方式,原理一样,只是代码路径不同,这里不做过多介绍。
源码路径:frameworks/base/packages/SystemUI/src/com/android/systemui/qs/tileimpl/QSFactoryImpl.java
public class QSFactoryImpl implements QSFactory {
private static final String TAG = "QSFactory";
private final QSTileHost mHost;
public QSFactoryImpl(QSTileHost host) {
mHost = host;
}
public QSTile createTile(String tileSpec) {
if (tileSpec.equals("wifi")) return new WifiTile(mHost);
else if (tileSpec.equals("bt")) return new BluetoothTile(mHost);
else if (tileSpec.equals("cell")) return new CellularTile(mHost);

else if (tileSpec.equals("nfc")) return new NfcTile(mHost);
// Intent tiles.
else if (tileSpec.startsWith(IntentTile.PREFIX)) return IntentTile.create(mHost, tileSpec);
else if (tileSpec.startsWith(CustomTile.PREFIX)) return CustomTile.create(mHost, tileSpec);
else {
Log.w(TAG, "Bad tile spec: " + tileSpec);
return null;
}
}
二:快捷开关功能实现
这里主要实现,打开开关弹出Notification(不可删除通知),关闭开关才能关闭通知。
源码路径:frameworks/base/packages/SystemUI/src/com/android/systemui/qs/tiles/HeadsetTile.java
- 继承
QSTile<QSTile.BooleanState>
- newTileState方法中
return new BooleanState()
- handleClick方法处理点击事件
- handleUpdateState方法更新状态信息
