获取小吃店支持库的高度 [英] get height of snackbar support library

问题描述

我正在使用Snackbar和fab支持库. 我想获取Snackbar的高度，该高度通过单行和多行消息给出正确的高度值.

I'm working with Snackbar and fab support library. I want to get height of Snackbar that gives correct height value with single line and multi line message.

var=mysnackbar.gethight();

，但是此代码不起作用，因为snackbar确实具有gethight().

but this code does not work because snackbar does have gethight().

推荐答案

小吃栏仅在调用show()方法之后才具有高度.尝试致电:

Snackbar will only has height after the show() method called. Try call:

mSnackbar.show();
int height = mSnackbar.getView.getHeight();

或者您可以使用回调函数来监听Snackbar的show事件并返回其高度，如下所示:

Or you can use the callback to listen for Snackbar is shown event and return its height as shown below:

mSnackbar.setCallback(new Snackbar.Callback {
    @Override
    Public void onDismissed(Snackbar snackbar, int event) {
    }

    @Override
    Public void onShown(Snackbar snackbar) {
        int height = snackbar.getView.getHeight();
    }
)
mSnackbar.show();
