使用環境：

普通的輸入框輸入數據時，界面上移已經滿足不了變態的項目經理……

使用方法：

1 清單文件常規聲明

android:screenOrientation="portrait"
    android:windowSoftInputMode="stateHidden|adjustPan"

2 xml文件中部分屬性配置：

3  代碼獲取虛擬鍵盤彈出后各個佈局的具體數據，并進行比對獲取到一個合適的上移距離：

int srollHeight, recordVisibleRec;
        private void controlKeyboardLayout(final View root, final View scrollToView) {
            root.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
                @Override
                public void onGlobalLayout() {
                    //獲取當前界面的高度    虛擬鍵盤的頂點位置也就是當前界面的底部高度
                    Rect rect = new Rect();
                    root.getWindowVisibleDisplayFrame(rect);
                    int rootInvisibleHeight = root.getRootView().getHeight() - rect.bottom;
                    if (Math.abs(rootInvisibleHeight - recordVisibleRec) > 200) {
                        if (rootInvisibleHeight > 200) {
                            int[] location = new int[2];
                            scrollToView.getLocationInWindow(location);
                            srollHeight = (location[1] + scrollToView.getHeight()) - rect.bottom;
                            srollHeight = 0 - (srollHeight /4);
                            ObjectAnimator objectAnimator = ObjectAnimator.ofFloat(scrollToView, "translationY", 0f, srollHeight);
                            objectAnimator.setDuration(500);
                            objectAnimator.start();
                        } else {
                            ObjectAnimator objectAnimator = ObjectAnimator.ofFloat(scrollToView, "translationY", srollHeight, 0f);
                            objectAnimator.setDuration(500);
                            objectAnimator.start();
                        }
                    }
                    recordVisibleRec = rootInvisibleHeight;
                }
            });
        }

具體更好的優化方案在摸索中，目前也是初步探索……
