Question

美好的一天！我很难掌握我的一些控件的协调性。我想澄清一下，控件位于父活动中显示的片段内。我需要这个在LinearLayout上运行。

我已经读过问题在于我们执行检索的顺序，所以我确实尝试使用view.post(new Runnable) and getTranslationX()，它产生了相同的结果。

其他参考文献将不胜感激。谢谢。

getHeight returns 0 for all Android UI objects

View getX() and getY() return 0.0 after they have been added to the Activity

修改：我发现了一些令人震惊的事情。我决定为什么不尝试将代码附加到一个按钮，看看我们是否可以获得任何值，当我执行并运行应用程序然后按下按钮时，我得到0！到底是怎么回事？

修改：将API级别从9更改为11.产生相同的结果。

以下是代码：

//this class extends fragment
    @SuppressLint("NewApi")
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        view = inflater.inflate(R.layout.game_sh_view, container, false);

        view.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                //1.    Fetch the controls
                getControls();

                //2.    Add function to the controls
                setControlFunctions();

                //3.    Execute on Init settings
                getScreenSize();
                locateControls();
                threadingMethods();

                //4.    Misc onInit commands
                onInitAesthetics();
            }
        });

        return view;
    }

    float screenSizeX;
    float screenSizeY;
    @RequiresApi(api = Build.VERSION_CODES.HONEYCOMB_MR2)
    public void getScreenSize(){
        WindowManager wm = getActivity().getWindowManager();
        Display disp = wm.getDefaultDisplay();
        Point size = new Point();
        disp.getSize(size);
        screenSizeX = size.x;
        screenSizeY = size.y;
        sop("=============SCREEN SIZE==============");
        sop("Screen Size X: "+size.x);
        sop("Screen Size Y: "+size.y);
        sop("============SCREEN SIZE END===========");
    }
    @RequiresApi(api = Build.VERSION_CODES.HONEYCOMB_MR2)
    public void locateControls(){
        comLeftYLocation = comLeft.getY();
        comLeftYPermLocation = comLeft.getY();
        sop("=============comLeft LOCATOR==============");
        sop("comLeft Location Y: "+comLeft.getY());
        sop("============comLeft LOCATOR END===========");
    }
