Quickly generate title

1、QuickSettingService

self-built

//继承TileService
public class QuickSettingService extends TileService{
    private final int STATE_OFF = 0;
    private final int STATE_ON = 1;
    private final String LOG_TAG = "QuickSettingService";
    private int toggleState = STATE_ON;
    //当用户从Edit栏添加到快速设定中调用
    @Override
    public void onTileAdded() {
        Log.d(LOG_TAG, "onTileAdded");
    }
    //当用户从快速设定栏中移除的时候调用
    @Override
    public void onTileRemoved() {
        Log.d(LOG_TAG, "onTileRemoved");
    }
    // 点击的时候
    @Override
    public void onClick() {
        Log.d(LOG_TAG, "onClick state = " + Integer.toString(getQsTile().getState()));
        Icon icon;
        if (toggleState == STATE_ON) {
            toggleState = STATE_OFF;
            icon =  Icon.createWithResource(getApplicationContext(), R.drawable.ic_videocam_off);
            getQsTile().setState(Tile.STATE_INACTIVE);// 更改成非活跃状态
        } else {
            toggleState = STATE_ON;
            icon = Icon.createWithResource(getApplicationContext(), R.drawable.ic_videocam);
            getQsTile().setState(Tile.STATE_ACTIVE);//更改成活跃状态
        }

        getQsTile().setIcon(icon);//设置图标
        getQsTile().updateTile();//更新Tile
    }
    // 打开下拉菜单的时候调用,当快速设置按钮并没有在编辑栏拖到设置栏中不会调用
    //在TleAdded之后会调用一次
    @Override
    public void onStartListening () {
        Log.d(LOG_TAG, "onStartListening");
    }
    // 关闭下拉菜单的时候调用,当快速设置按钮并没有在编辑栏拖到设置栏中不会调用
    // 在onTileRemoved移除之前也会调用移除
    @Override
    public void onStopListening () {
        Log.d(LOG_TAG, "onStopListening");
    }

}
