如上，我红色指着的方向是一个输入框，它被挡住了。我整个灰色的是popuwindow

参考的网站

Android中获取软键盘状态和软键盘高度

代码实现

  //屏幕高度
    int screenHeight = 0;
    public interface OnSoftKeyboardStateChangedListener {
        public void OnSoftKeyboardStateChanged(boolean isKeyBoardShow, int keyboardHeight);
    }
    //注册软键盘状态变化监听
    public void addSoftKeyboardChangedListener(SchedulingActivity.OnSoftKeyboardStateChangedListener listener) {
        if (listener != null) {
            mKeyboardStateListeners.add(listener);
        }
    }
    //取消软键盘状态变化监听
    public void removeSoftKeyboardChangedListener(SchedulingActivity.OnSoftKeyboardStateChangedListener listener) {
        if (listener != null) {
            mKeyboardStateListeners.remove(listener);
        }
    }
    private ArrayList<SchedulingActivity.OnSoftKeyboardStateChangedListener> mKeyboardStateListeners;      //软键盘状态监听列表
    private ViewTreeObserver.OnGlobalLayoutListener mLayoutChangeListener;
    private boolean mIsSoftKeyboardShowing;
    protected void onCreate(Bundle savedInstanceState) {
       WindowManager wm = (WindowManager) this.getSystemService(Context.WINDOW_SERVICE);
        DisplayMetrics dm = new DisplayMetrics();
        wm.getDefaultDisplay().getMetrics(dm);
        screenHeight = dm.heightPixels; // 屏幕高度（像素）
        //屏幕高度
        mIsSoftKeyboardShowing = false;
        mKeyboardStateListeners = new ArrayList<SchedulingActivity.OnSoftKeyboardStateChangedListener>();
        mLayoutChangeListener = new ViewTreeObserver.OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                //判断窗口可见区域大小
                Rect r = new Rect();
                getWindow().getDecorView().getWindowVisibleDisplayFrame(r);
                //如果屏幕高度和Window可见区域高度差值大于整个屏幕高度的1/3，则表示软键盘显示中，否则软键盘为隐藏状态。
                int heightDifference = screenHeight - (r.bottom - r.top);
                boolean isKeyboardShowing = heightDifference > screenHeight / 3;

                //如果之前软键盘状态为显示，现在为关闭，或者之前为关闭，现在为显示，则表示软键盘的状态发生了改变
                if ((mIsSoftKeyboardShowing && !isKeyboardShowing) || (!mIsSoftKeyboardShowing && isKeyboardShowing)) {
                    mIsSoftKeyboardShowing = isKeyboardShowing;
                    for (int i = 0; i < mKeyboardStateListeners.size(); i++) {
                        SchedulingActivity.OnSoftKeyboardStateChangedListener listener = mKeyboardStateListeners.get(i);
                        listener.OnSoftKeyboardStateChanged(mIsSoftKeyboardShowing, heightDifference);
                    }
                }
            }
        };
        //注册布局变化监听
        getWindow().getDecorView().getViewTreeObserver().addOnGlobalLayoutListener(mLayoutChangeListener);
        showBottomView();
}

 public void showBottomView() {
   if (bottomView == null) {
           addSoftKeyboardChangedListener(new SchedulingActivity.OnSoftKeyboardStateChangedListener() {
                @Override
                public void OnSoftKeyboardStateChanged(boolean isKeyBoardShow, int keyboardHeight) {
                    if (isKeyBoardShow) {//软键盘显示，这里设置了控制底部多少距离
                        int paddingBottom = DensityUtil.dip2px(BAFApplication.getApplication(), linearLayoutPopuMenuParent.getPaddingBottom() + 30);
                        linearLayoutPopuMenuParent.setPadding(linearLayoutPopuMenuParent.getPaddingLeft(), linearLayoutPopuMenuParent.getPaddingTop(), linearLayoutPopuMenuParent.getPaddingRight(), paddingBottom);
                    } else {//软键盘没有显示，当软键盘没有显示的时候，就要还原
                        linearLayoutPopuMenuParent.setPadding(linearLayoutPopuMenuParent.getPaddingLeft(), linearLayoutPopuMenuParent.getPaddingTop(), linearLayoutPopuMenuParent.getPaddingRight(), 0);
                    }
                }
            });
     }
}

protected void onDestroy() {
    //移除布局变化监听
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
        getWindow().getDecorView().getViewTreeObserver().removeOnGlobalLayoutListener(mLayoutChangeListener);
    } else {
        getWindow().getDecorView().getViewTreeObserver().removeGlobalOnLayoutListener(mLayoutChangeListener);
    }
    super.onDestroy();
};

工具类

public class DensityUtil {
    private static DensityUtil densityUtil;

    public static DensityUtil getInstance() {
        if (densityUtil == null) {
            densityUtil = new DensityUtil();
        }
        return densityUtil;//返回一个实例
    }

    /**

     */
    public static int dip2px(Context context, float dpValue) {
        final float scale = context.getResources().getDisplayMetrics().density;
        return (int) (dpValue * scale + 0.5f);
    }
