代码实现
//屏幕高度

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

}

//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

}
}
}
};
//注册布局变化监听

showBottomView();
}

}
}
});
}
}
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 {

};
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
}
/**

*/

return (int) (dpValue * scale + 0.5f);
}

将工具方法抽离出来
使用教程
KeyBordChangeUtils keyBordChangeUtils = new KeyBordChangeUtils(this.getActivity());
if (keyBordChangeUtils!=null){
//注册监听
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) {//软键盘显示，这里设置了控制底部多少距离
layoutParams.bottomMargin = keyboardHeight +DensityUtil.getInstance().dip2px(10);
productInfoPopuwindow.getPopuwindowLinlayoutParent().setLayoutParams(layoutParams);
} else {//软键盘没有显示，当软键盘没有显示的时候，就要还原
layoutParams.bottomMargin = 0;
productInfoPopuwindow.getPopuwindowLinlayoutParent().setLayoutParams(layoutParams);
}
}
});
}
注意点：
keyboardHeight:包含了状态栏的高度
