android - Toolbar vs appcompat v7-21 toolbar

Question

What is the difference between the two? what all features are included in toolbar thats not in v7-21 toolbar? What all limitations are there in using v7-21 tollbar in place of toolbar?

Answer 1

如果您查看Toolbar和AppCompat Toolbar的文档，您会发现在功能上，两者之间没有任何区别。当然，两者所需的 SDK 级别不同，要使用Toolbar你必须调用setActionBar(mToolbar);，但Toolbar你必须调用支持setSupportActionBar(mToolbar);
