android 8.1 SystemUI修改 QuickSetting 新增快捷设置图标

SystemUI源文件在frameworks\base\packages\SystemUI目录下

1.资源文件设置

在 res/values/config.xml文件中找到

   <string name="quick_settings_tiles_default" translatable="false">
        hotspot,location,rotation,work,inversion,cell,nfc,wifi,dnd,bt,flashlight,rotation,battery,cell,airplane,cast,screenshot,browser
    </string>

这是默认显示的快捷设置，这里我自定义的快捷设置为browser,将它添加到最后。

在strings.xml中设置快捷方式的名称

<string name="quick_settings_ringer_browser">浏览器</string>

在res/drawable目录下新增按钮图片

本文直接用NFC的图片资源（ic_qs_nfc_enabled.xml）

找到frameworks\base\proto\src\metrics_constants.proto 文件

新增：

QS_BROWSER = 1146;

注意：metrics_constants.proto文件 修改完成后 mma重新编译生效

2.原始代码修改

com.android.systemui.qs.QSTileHost.java

因为默认读取数据库的文件，所以想要配置文件生效，将数据库置空，这样会读取配置文件。

    protected List<String> loadTileSpecs(Context context, String tileList) {
        final Resources res = context.getResources();
        tileList = null; //chenzq: 这里修改屏蔽了数据库的默认设置，强制读取配置文件
        final String defaultTileList = res.getString(R.string.quick_settings_tiles_default);
        if (tileList == null) {
            tileList = res.getString(R.string.quick_settings_tiles);
            if (DEBUG) Log.d(TAG, "Loaded tile specs from config: " + tileList);
        } else {
            if (DEBUG) Log.d(TAG, "Loaded tile specs from setting: " + tileList);
        }
        Log.d("chenzq0", tileList);
        final ArrayList<String> tiles = new ArrayList<String>();
        boolean addedDefault = false;
        for (String tile : tileList.split(",")) {
            tile = tile.trim();
            if (tile.isEmpty()) continue;
            if (tile.equals("default")) {
                if (!addedDefault) {
                    tiles.addAll(Arrays.asList(defaultTileList.split(",")));
                    addedDefault = true;
                }
            } else {
                tiles.add(tile);
            }
        }
        return tiles;
    }

 com.android.systemui.qs.tileimpl.QSFactortImpl.java

在createTile方法中新增返回自定义Tile

注意：别忘了导入自定义文件的包

    public QSTile createTile(String tileSpec) {
        Log.d("chenzq1", 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("dnd")) return new DndTile(mHost);
        else if (tileSpec.equals("inversion")) return new ColorInversionTile(mHost);
        else if (tileSpec.equals("airplane")) return new AirplaneModeTile(mHost);
        else if (tileSpec.equals("work")) return new WorkModeTile(mHost);
        else if (tileSpec.equals("rotation")) return new RotationLockTile(mHost);
        else if (tileSpec.equals("flashlight")) return new FlashlightTile(mHost);
        else if (tileSpec.equals("location")) return new LocationTile(mHost);
        else if (tileSpec.equals("cast")) return new CastTile(mHost);
        else if (tileSpec.equals("hotspot")) return new HotspotTile(mHost);
        else if (tileSpec.equals("user")) return new UserTile(mHost);
        else if (tileSpec.equals("battery")) return new BatterySaverTile(mHost);
        else if (tileSpec.equals("saver")) return new DataSaverTile(mHost);
        else if (tileSpec.equals("night")) return new NightDisplayTile(mHost);
        else if (tileSpec.equals("nfc")) return new NfcTile(mHost);
        else if (tileSpec.equals("browser")) return new BrowserTile(mHost);//新增自定义Tile
        // 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 if (tileSpec.equals("screenshot")) return new ScreenShotTile(mHost);
        
        else {
            Log.w(TAG, "Bad tile spec: " + tileSpec);
            return null;
        }
    }

3.新建自己的Tile类

com.android.systemui.qs.tiles目录下新建BrowserTile.java

要继承QSTileImpl类

package com.android.systemui.qs.tiles;
import android.content.Intent;
import android.util.Log;
import android.service.quicksettings.Tile;
import com.android.systemui.R;
import com.android.systemui.qs.tileimpl.QSTileImpl;
import com.android.systemui.qs.QSHost;
import com.android.systemui.plugins.qs.QSTile;
import com.android.systemui.plugins.qs.QSTile.BooleanState;
import com.android.internal.logging.nano.MetricsProto.MetricsEvent;


public class BrowserTile extends QSTileImpl<BooleanState>{

public BrowserTile(QSHost host) {
    super(host);
    Log.d("chenzq1", "browser creating");

    }

    @Override
    public int getMetricsCategory() {
        return MetricsEvent.QS_BROWSER;//返回frameworks\base\proto\src\metrics_constants.proto中新增的定义

    }

    @Override
    public CharSequence getTileLabel() {
        return mContext.getString(R.string.quick_settings_ringer_browser);//返回Strings.xml定义的文件名
    }

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


    //长按快捷图标跳转计算器
    @Override
    public Intent getLongClickIntent() {
        Log.d("chenzq2", "browser creating3");
        Intent intent =new Intent();
        intent.setClassName("com.android.calculator2", "com.android.calculator2.Calculator");
        return new Intent(intent);
    }

    //单击快捷图标跳转浏览器
    @Override
    protected void handleClick() {
        Log.d("chenzq2", "browser creating4");
        Intent intent =new Intent();
        intent.setClassName("org.chromium.webview_shell","org.chromium.webview_shell.WebViewBrowserActivity");
        mContext.startActivity(intent);
    }
    
    //图标的构建
    @Override
    protected void handleUpdateState(BooleanState state, Object arg) {
        Log.d("chenzq1", "browser creating2");
            state.label = mContext.getString(R.string.quick_settings_ringer_browser);
            state.icon = ResourceIcon.get(R.drawable.ic_qs_nfc_enabled);
            state.state = Tile.STATE_ACTIVE;

    }
    

    @Override
    public void handleSetListening(boolean listening) {

    }


}
