如何轻松地"显示布局界限"进行Android调试？

Question

我想观看App的布局而不用无聊和点击.

---

我试过adb shell setprop debug.layout true但除非重启或打开设置,否则无效.
这可能是由于设置没有更新造成的.

我尝试用代码编写一个小应用程序SystemProperties.set("debug.layout", "true"),也没用.
也许该应用程序的权威......

对不起,我的英语很差,感谢您的帮助:p

这对我有用:

adb shell setprop debug.layout true
adb shell service call activity 1599295570

在我们启用了Show layout bounds using之后adb shell setprop debug.layout true,我们必须戳一下SystemProperties以查看更改为Show Layout bounds QS Tiles:

@Override
public void onClick() {
    setIsEnabled(getQsTile().getState() == Tile.STATE_INACTIVE);
    new DevelopmentSettings.SystemPropPoker().execute(); // Settings app magic
    refresh();
}

这是AOSP源的原始方法:

public static class SystemPropPoker extends AsyncTask<Void, Void, Void> {
    @Override
    protected Void doInBackground(Void... params) {
        String[] services = ServiceManager.listServices();
        for (String service : services) {
            IBinder obj = ServiceManager.checkService(service);
            if (obj != null) {
                Parcel data = Parcel.obtain();
                try {
                    obj.transact(IBinder.SYSPROPS_TRANSACTION, data, null, 0);
                } catch (RemoteException e) {
                } catch (Exception e) {
                    Log.i(TAG, "Someone wrote a bad service '" + service
                            + "' that doesn't like to be poked: " + e);
                }
                data.recycle();
            }
        }
        return null;
    }
}

号码1599295570被呼叫SYSPROPS_TRANSACTION

您无需启动设置应用.只需退出您的应用,设置属性,然后启动您的应用即可.

adb shell am force-stop com.company.appname ; adb shell setprop debug.layout true ; adb shell monkey -p com.company.appname -c android.intent.category.LAUNCHER 1

我发现DevelopQuickSetting工具可以轻松实现这一目标。 https://github.com/kyze8439690/DevelopQuickSetting

而转换为adb shel的核心代码是：

adb shell setprop debug.layout true
adb shell service check SurfaceFlinger
