android - 什么都不调整时如何获得键盘高度？

Question

我正在尝试使用以下代码获取 android 键盘高度。

popupWindow 解决方案在某些设备上不起作用，还有其他解决方案吗？

parentLayout.getViewTreeObserver().addOnGlobalLayoutListener(
            new ViewTreeObserver.OnGlobalLayoutListener() {

                @Override
                public void onGlobalLayout() {

                    Rect r = new Rect();
                    parentLayout.getWindowVisibleDisplayFrame(r);

                    int screenHeight = parentLayout.getRootView().getHeight();
                    int heightDifference = screenHeight - (r.bottom);

                    previousHeightDiffrence = heightDifference;

                       if (heightDifference > 100) {
                        isKeyBoardVisible = true;
                        changeKeyboardHeight(heightDifference);

                    } else {

                       if(emojiKeyboard.getVisibility()==View.INVISIBLE){
                          emojiKeyboard.setVisibility(View.GONE);
                        }

                       isKeyBoardVisible = false;
                    }

                }
            });

Answer 1

我会选择insets解决方案——rootWindowInsets.systemWindowInsetBottom如果存在的话，哪里会包括键盘。看看文档

Answer 2

final Window mRootWindow = getWindow();
        ll_main.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener(){
            public void onGlobalLayout(){
                int screenHeight = ll_main.getRootView().getHeight();
                Rect r = new Rect();
                View view = mRootWindow.getDecorView();
                view.getWindowVisibleDisplayFrame(r);

                int keyBoardHeight = screenHeight - r.bottom;
            }
        });
