修復輸入法及彈出輸入法動態修改UI佈局

先看未修復之前的UI圖

這是修復後的UI 動圖

git圖片能看到佈局是隨之變化的，怎麼做呢？

• 第一步 添加配置

在Activity配置文件中中添加android:windowSoftInputMode="stateAlwaysVisible|adjustResize" 

• 第二步 監聽鍵盤彈起

    viewMove 移動的View;
    container 要做修復的佈局;
    viewStationary固定的View的最下部佈局;
@Override
    protected void onStart() {
        super.onStart();
        int height = ScreenUtils.getScreenHeight();//獲取屏幕高度
        viewMove.addOnLayoutChangeListener((v, left, top, right, bottom, oldLeft, oldTop, oldRight, oldBottom) ->//監聽浮動的View 佈局變化
        {
            if (height - bottom > height * 0.3f) {//默認佈局變化大於0.3就是輸入法彈出了，這裏判斷輸入法是否彈出
                LogUtil.e("-----up ----");
                float staY = viewStationary.getY();
                float moveY = viewMove.getY();
                float scroll = moveY - staY;
                int fix = SizeUtils.dp2px(20);//這裏設定了固定View 和 浮動View的距離是最小20dp，大於20dp後不用處理
                if (scroll < fix) {
                    ViewAnimator.animate(container).translationY(scroll - fix).duration(200).start();//動畫處理，自行處理
                }
            } else {
                LogUtil.e("-----down ----");
                ViewAnimator.animate(container).dp().translationY(0).duration(200).start();
            }
        });
    }

此乃佈局
