如何通过CoordinatorLayout将TextView移动到工具栏中?

标签: android android-recyclerview android-coordinatorlayout

我正在构建一个由工具栏组成的coordinator layout,一个隐藏在滚动上的相对布局,一个始终位于scrollable list之上的静态布局,以及RecyclerView

我目前按照我的要求进行布局,如下所示:

  • 绿色是工具栏
  • 橙色是隐藏在滚动上的相对布局
  • 红色是我的静态布局,要保持在回收者视图之上 向上移动,但不要隐藏。
  • 白色是我的RecyclerView

下一张图片就是我在回收者视图中向上滚动的样子。

所以我的橙色视图隐藏在我想要的地方,这是完美的。我唯一缺少的一步就是移动"标题1" textview成为工具栏的标题。我已经看过一些例子,他们已经用图像做了类似的事情,但是还没有能够通过自定义行为复制它。我假设这会是什么?

有没有人对我的布局是否需要更改以使其成为可能有任何建议,以及任何有关自定义行为的建议,如果这将是什么?

编辑:

我取得了一些进展。我想我的布局是我想要的,并且我已经开始行为了。我可以移动TextView,但它在工具栏后面丢失了。我想让它放在工具栏的顶部。我的目标是将标题从黄色块移动到绿色块中。

我是否需要调整布局,以便将textview显示在标题栏的顶部?

您必须在工具栏中创建TextView并根据需要设置重力。对于您的问题,没有必要采取工具栏,您也可以使用布局。这是我的坐标布局。您可以在其中轻松调整工具栏内的TextView。

My goal is to move the title from the yellow block into the green block.

As your goal is to set the Title from the yellow block into the green there is no need to move Textview in yellow block you can set Title in yellow block with setTitle property of Toolbar.

setCollapseMode with Toolbar you can set it to COLLAPSE_MODE_OFF/COLLAPSE_MODE_PARALLAX/COLLAPSE_MODE_PIN

More Detail on CollapseMode

<android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            app:layout_scrollFlags="scroll|enterAlways"
            app:layout_collapseMode="pin" /> // to  pin in place until it reaches the bottom of the layout

Implement AppBarLayout.OnOffsetChangedListener listener on your AppBarLayout to determine the CollpasingToolbar is collapsed or not and set Title in the Toolbar accordingly.

Call below method on OnCreate() of Activity.

 private void setTitleOfLayout() {
        AppBarLayout appBarLayout = findViewById(R.id.appbar_layout);
        appBarLayout.addOnOffsetChangedListener(new AppBarLayout.OnOffsetChangedListener() {
            boolean isShow;
            int scrollRange = -1;

            @Override
            public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
                if (scrollRange == -1) {
                    scrollRange = appBarLayout.getTotalScrollRange();
                }
                if (scrollRange + verticalOffset == 0) {

                  // orange part is not visible so set The title 

                    if (myTitleName != null)
                        toolbar.setTitle(myTitleName);

                    isShow = true;
                } else if (isShow) {
                     // orange part is visible so remove the title with

                      space here make sure your are not setting null in toolbar.

                    toolbar.setTitle(" ");

                    isShow = false;
                }
            }
        });

    }

您必须为要移动,调整大小,隐藏等的每个元素编写自定义行为...

只需创建一个从CoordinatorLayout.Behavior<View>扩展的类并实现您想要的,最后将widget app:layout_behavior设置为您编写的自定义行为。

在git hub CoordinatorBehavior
