Android8.1 下拉状态栏添加铃声静音快捷键简单记录

Android8.1 下拉状态栏添加铃声静音快捷键简单记录
1.修改quick_settings_tiles_default

    
    
        wifi,bt,dnd,battery,cell,airplane
    

由于如果直接在airplane后加ring会导致显示不全ring无法显示在一次下拉中（只能在下拉一次后再次下拉的时候才能显示，如果要强改可能需要改布局文件造成更多的修改），并且dnd（免打扰功能）没有需求，所以直接把dnd换成ring。

    
    
        wifi,bt,ring,battery,cell,airplane
    

2.metrics_constants.proto中添加 QS_RING = 1145;

//frameworks\base\proto\src\metrics_constants.proto

    // logged when we cancel an app transition.
    APP_TRANSITION_CANCELLED = 1144;

    QS_RING = 1145;


    // ---- End O-MR1 Constants, all O-MR1 constants go above this line ----

    // Add new aosp constants above this line.
    // END OF AOSP CONSTANTS
  }
}

3.新建RingTile ，修改QSFactoryImpl。

在createTile中添加else if (tileSpec.equals("ring")) {return new RingTile(mHost);}

public class QSFactoryImpl implements QSFactory {
.............
    public QSTile createTile(String tileSpec) {
        /// M: Add extra tiles in quicksetting @{
        Context context = mHost.getContext();
        IQuickSettingsPlugin quickSettingsPlugin = OpSystemUICustomizationFactoryBase
                .getOpFactory(context).makeQuickSettings(context);
        /// @}
        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("ring")) {
            return new RingTile(mHost);
        }
        .............
        }
    }

新建RingTile。

public class RingTile extends QSTileImpl {
    private boolean mListening;
    private AudioManager mAudioManager;
    private final GlobalSetting mGlobalSetting;
    private boolean isRingerModeSilent;

    public RingTile(QSHost host) {
        super(host);
        mAudioManager = (AudioManager) mContext.getSystemService(mContext.AUDIO_SERVICE);
        mGlobalSetting = new GlobalSetting(mContext, mHandler, Settings.System.MODE_RINGER_STREAMS_AFFECTED) {
            @Override
            protected void handleValueChanged(int value) {
                handleRefreshState(value);
            }
        };
    }

    @Override
    public int getMetricsCategory() {
        return MetricsEvent.QS_RING;
    }

    @Override
    public CharSequence getTileLabel() {
        return mContext.getString(R.string.quick_settings_ringer_silent);
    }

    @Override
    public BooleanState newTileState() {
        return new BooleanState();
    }

    @Override
    public void handleSetListening(boolean listening) {
        if (mListening == listening) return;
        mListening = listening;
        mGlobalSetting.setListening(mListening);
    }

  //长按快捷图标跳转对应设置
    @Override
    public Intent getLongClickIntent() {
        return new Intent(Settings.ACTION_SOUND_SETTINGS);
    }

    @Override
    protected void handleClick() {
        if (mAudioManager.getRingerMode()!= AudioManager.RINGER_MODE_SILENT) {
            mAudioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);
        } else {
            mAudioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
        }
        refreshState();
    }

    @Override
    protected void handleUpdateState(BooleanState state, Object arg) {
        state.label = mContext.getString(R.string.quick_settings_ringer_silent);
        if (mAudioManager.getRingerMode() == AudioManager.RINGER_MODE_SILENT) {
            state.icon = ResourceIcon.get(R.drawable.ic_qs_ringer_silent);
            state.state = Tile.STATE_ACTIVE;
        } else {
            state.icon = ResourceIcon.get(R.drawable.ic_qs_ringer_audible);
            state.state = Tile.STATE_INACTIVE;
        }
    }

}

定义Silent的string。

//vendor\mediatek\proprietary\packages\apps\SystemUI\res\values\strings.xml
Silent

state.state这个属性，跟图标的最终显示颜色有关。system ui中的下拉栏中的图标基本是svg图片，fillColor属性为 #FFFFFFFF，但是最终显示却不是白色，是因为setTint，动态修改了颜色。

//vendor\mediatek\proprietary\packages\apps\SystemUI\src\com\android\systemui\qs\tileimpl\QSIconViewImpl.java
    protected void setIcon(ImageView iv, QSTile.State state) {
        updateIcon(iv, state);
        if (state.disabledByPolicy) {
            iv.setColorFilter(getContext().getColor(R.color.qs_tile_disabled_color));
        } else {
            iv.clearColorFilter();
        }
        if (state.state != mState) {
            int color = getColor(state.state);
            mState = state.state;
            if (iv.isShown() && mTint != 0) {
                animateGrayScale(mTint, color, iv);
                mTint = color;
            } else {
                if (iv instanceof AlphaControlledSlashImageView) {
                    ((AlphaControlledSlashImageView)iv)
                            .setFinalImageTintList(ColorStateList.valueOf(color));
                } else {
                    setTint(iv, color);
                }
                mTint = color;
            }
        }
    }
