    </android.support.design.widget.CoordinatorLayout>

这是我得到的输出如何在标题文本中使用图标。

在 Java 中

 mRootLayout = (CoordinatorLayout) findViewById(R.id.coordinatorRootLayout);
    mCollapsingToolbarLayout = (CollapsingToolbarLayout) findViewById(R.id.collapsingToolbarLayoutAndroidExample);
    mCollapsingToolbarLayout.setExpandedTitleColor(getResources().getColor(R.color.black));
    mCollapsingToolbarLayout.setTitle("My App Title");

【讨论】：

我试过这个库，但它不是我想要的，请参阅 iOS gif。并比较这个库，不匹配。您会更改我的代码以实现输出吗？在这个库中，工具栏就存在于卡片视图之前，并在滚动时向上。我不要那个。再加上在此实现 gridview 存在问题。
我只有 xml 代码。并在java中初始化布局。我更新了代码
