Android多行小吃店 [英] Android Multiline Snackbar

问题描述

我正在尝试利用Android设计支持库中的新Snackbar来显示多行小吃栏，如

I'm trying to leverage new Snackbar from Android Design Support Library to display multiline snackbar, as shown in http://www.google.com/design/spec/components/snackbars-toasts.html#snackbars-toasts-specs:

import android.support.design.widget.Snackbar;

final String snack = "First line\nSecond line\nThird line";
Snackbar.make(mView, snack, Snackbar.LENGTH_LONG).show();

它在我的Nexus 7上仅显示First line....如何使其显示所有行?

It displays only First line... on my Nexus 7. How to make it display all lines?

PS:我尝试了Toast，它显示了所有行.

PS: I tried Toast and it displayed all lines.

推荐答案

只需设置Snackbars Textview的maxLines属性

Just set the maxLines attribute of Snackbars Textview

View snackbarView = snackbar.getView();
TextView textView = (TextView) snackbarView.findViewById(android.support.design.R.id.snackbar_text);
textView.setMaxLines(5);  // show multiple line

如果您使用的是最新的"com.google.android.material:material:1.0.0"依赖项，则将使用以下内容:com.google.android.material.R.id.snackbar_text来访问Snackbar的TextView.

您甚至可以使用R.id.snackbar_text.这对我有用.

If you're using the more recent "com.google.android.material:material:1.0.0"dependency, then you will use this: com.google.android.material.R.id.snackbar_text to access the Snackbar's TextView.

You can use even R.id.snackbar_text as well. it's work for me.
