[原创]用代码dialog 高度 宽度无法屏幕屏幕问题

不做笔记全给忘记了，因为百度都是不靠谱的答案，所以探索出来的东西还是发不出来笔记号

public static <T extends ViewDataBinding> Pair<Dialog,T> getDialog(Context context, @LayoutRes int layout, Class<T> parent_, ViewGroup viewGroup) {
        Dialog dialog = new Dialog(context);


        Window window = dialog.getWindow();
        WindowManager.LayoutParams lp = window.getAttributes();
        window.getDecorView().setPadding(0, 0, 0, 0);
        lp.dimAmount = 0;//dimAmount在0.0f和1.0f之间，0.0f完全不暗，1.0f全暗
        lp.width = ViewGroup.LayoutParams.MATCH_PARENT;

pad上状态栏被填充的问题
如果是toolbar,那就把toolbar的padding多设置一点

int[] position=new int[2];
                dialogPair.second.getRoot().getLocationOnScreen(position);
                if (position[0] == 0) {
                    int statusBarHeight = AppUtils.getStatusBarHeight(getThis());
//                    FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
                    dialogPair.second.toolbar.setPadding(0,statusBarHeight,0,0);//处理pad 布局填充到状态栏问题
                }

或者自定义一个view到状态栏
这个问题只有在pad上自定义状态栏颜色才会出现

int[] position = new int[2];
                    dataBinding.getRoot().getLocationOnScreen(position);
                    if (position[0] == 0) {
                        int statusBarHeight = AppUtils.getStatusBarHeight(getThis());
                        FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
                        params.topMargin = statusBarHeight;
                        View view = new View(dataBinding.getRoot().getContext());
                        view.setBackgroundColor(getThis().getResources().getColor(R.color.themeColor));
                        ViewGroup viewGroup = (ViewGroup) dataBinding.getRoot();
                        viewGroup.addView(view, new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, AppUtils.getStatusBarHeight(getThis())));
                        dataBinding.nestedScrollView.setPadding(0,statusBarHeight,0,0);//解决直接到顶问题。
                        dataBinding.btnClose.setPadding(dataBinding.btnClose.getPaddingLeft(),dataBinding.btnClose.getPaddingTop()+statusBarHeight,dataBinding.btnClose.getPaddingRight(),dataBinding.btnClose.getPaddingBottom());
                    }

上面修复状态栏代码在show之后使用

上面代码使用x y为0 这就解决了getLocationOnScreen()获取时机不对导致为0 问题。

dataBinding.getRoot().addOnLayoutChangeListener(new View.OnLayoutChangeListener() {
                    @Override
                    public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {
                        int[] position = new int[2];
                        dataBinding.getRoot().getLocationOnScreen(position);
                            int statusBarHeight = position[1] == 0?AppUtils.getStatusBarHeight(getThis()):0;
                            FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
                            params.topMargin = statusBarHeight;
                            View view = new View(dataBinding.getRoot().getContext());
                            view.setBackgroundColor(getThis().getResources().getColor(R.color.themeColor));
                            ViewGroup viewGroup = (ViewGroup) dataBinding.getRoot();
                            viewGroup.addView(view, new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, AppUtils.getStatusBarHeight(getThis())));
                            dataBinding.nestedScrollView.setPadding(0, statusBarHeight, 0, 0);//解决直接到顶问题。
                            dataBinding.btnClose.setPadding(dataBinding.btnClose.getPaddingLeft(), dataBinding.btnClose.getPaddingTop() + statusBarHeight, dataBinding.btnClose.getPaddingRight(), dataBinding.btnClose.getPaddingBottom());
                        Log.w("XY", Arrays.toString(position));
                    }
                });
