如上，我紅色指著的方向是一個輸入框坐桩，它被擋住了瘟斜。我整個灰色的是popuwindow

將工具方法抽離出來
使用教程
KeyBordChangeUtils keyBordChangeUtils = new KeyBordChangeUtils(this.getActivity());
if (keyBordChangeUtils!=null){
//注冊監(jiān)聽
keyBordChangeUtils.addSoftKeyboardChangedListener(new KeyBordChangeUtils.OnSoftKeyboardStateChangedListener() {
@Override
public void OnSoftKeyboardStateChanged(boolean isKeyBoardShow, int keyboardHeight) {
if (productInfoPopuwindow==null){
return;
}
FrameLayout.LayoutParams layoutParams = (FrameLayout.LayoutParams) productInfoPopuwindow.getPopuwindowLinlayoutParent().getLayoutParams();
if (isKeyBoardShow) {//軟鍵盤顯示菲饼，這里設(shè)置了控制底部多少距離
layoutParams.bottomMargin = keyboardHeight +DensityUtil.getInstance().dip2px(10);
productInfoPopuwindow.getPopuwindowLinlayoutParent().setLayoutParams(layoutParams);
} else {//軟鍵盤沒有顯示待讳，當(dāng)軟鍵盤沒有顯示的時候，就要還原
layoutParams.bottomMargin = 0;
productInfoPopuwindow.getPopuwindowLinlayoutParent().setLayoutParams(layoutParams);
}
}
});
}
注意點：
keyboardHeight:包含了狀態(tài)欄的高度
