[英]Toolbar inside CollapsingToolbarLayout, Toolbar title not showing
I used CollapsingToolbarLayout
as the parent of Toolbar
, below it the layout 我使用CollapsingToolbarLayout
作为Toolbar
的父级,在它下面是布局
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/collapsing_toolbar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="@+id/test_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:minHeight="?attr/actionBarSize"
app:navigationIcon="@drawable/abc_ic_ab_back_mtrl_am_alpha"
app:theme="@style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
Then I want to set the title of the Toolbar
with the following code, but it didn't work. 然后我想用下面的代码设置Toolbar
的标题,但它不起作用。 The title just didn't show. 标题只是没有显示。
Toolbar toolbar = (Toolbar) findViewById(R.id.test_toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(true);
getSupportActionBar().setTitle("ABC");
I also tried set the title in CollapsingToolbarLayout
with the following code, it didn't work either. 我还尝试使用以下代码在CollapsingToolbarLayout
设置标题,它也不起作用。
CollapsingToolbarLayout collapsingToolbarLayout = (CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar_layout);
collapsingToolbarLayout.setTitleEnabled(true);
collapsingToolbarLayout.setTitle("ABC");
But if I removed CollapsingToolbarLayout
from my layout and make AppBarLayout
as the direct parent of Toolbar
, the code above to set the title of Toolbar
worked. 但是,如果我从布局中删除了CollapsingToolbarLayout
并将AppBarLayout
作为Toolbar
的直接父级,则上面的代码设置Toolbar
的标题。
Did I missed something? 我错过了什么吗? This issue is so weird. 这个问题太奇怪了。 Is it a bug in design support library? 这是设计支持库中的错误吗? How can I solve it without changing my layout? 如何在不改变布局的情况下解决问题?
This is a temporary solution. 这是一个临时解决方案。 I didn't investigate the code deeply, but by disabling the refresh of Toolbar
in CollapsingToolbarLayout
, it worked. 我没有深入调查代码,但通过在CollapsingToolbarLayout
禁用Toolbar
的刷新,它可以工作。
Here is what I did: 这是我做的:
public static void setRefreshToolbarEnable(CollapsingToolbarLayout collapsingToolbarLayout,
boolean refreshToolbarEnable) {
try {
Field field = CollapsingToolbarLayout.class.getDeclaredField("mRefreshToolbar");
field.setAccessible(true);
field.setBoolean(collapsingToolbarLayout, refreshToolbarEnable);
} catch (NoSuchFieldException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}
}
只需在xml中设置“折叠”工具栏“titleEnabled = false”,即可显示工具栏标题。
app:titleEnabled="false"
Move 移动
CollapsingToolbarLayout collapsingToolbarLayout = (CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar_layout);
collapsingToolbarLayout.setTitleEnabled(true);
collapsingToolbarLayout.setTitle("ABC");
from onCreate to onCreateView inside if 从onCreate到onCreateView里面if
try this : 试试这个 :
collapsingToolbarLayout.setTitleEnabled(false);
toolbar.setTitle("ABC");
