[英]How can I make a toolbar stay on the screen?
我有一個帶有一些TextViews和EditTexts的屏幕,以及一個工具欄。 當我單擊編輯文本以輸入一些文本時,工具欄消失了,即使引入文本(或滾動,如果引入滾動視圖),如何也可以使工具欄始終保持在屏幕上
<androidx.constraintlayout.widget.ConstraintLayout 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:id="@+id/createTreasureScreen"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:context=".view.fragment.CreateTreasureFragment">
<Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="@dimen/toolbarTreasureHeight"
android:background="@color/Blue"
android:elevation="@dimen/loginToolbarElevation"
android:title="@string/page_title"
android:titleMarginStart="@dimen/toolbarMarginStart"
android:titleTextAppearance="@style/toolbarStyle"
android:titleTextColor="@color/White"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="@id/parent"
app:titleEnabled="false" />
</androidx.constraintlayout.widget.ConstraintLayout>
嘗試使用FrameLayout
。 這將使您可以將Toolbar
始終保持在其他視圖的頂部,並且在添加ScrollView
可以看到。
<FrameLayout 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">
<androidx.constraintlayout.widget.ConstraintLayout
android:id="@+id/createTreasureScreen"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:context=".view.fragment.CreateTreasureFragment">
<!--Add your other views here-->
</androidx.constraintlayout.widget.ConstraintLayout>
<Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="@dimen/toolbarTreasureHeight"
android:background="@color/Blue"
android:elevation="@dimen/loginToolbarElevation"
android:title="@string/page_title"
android:titleMarginStart="@dimen/toolbarMarginStart"
android:titleTextAppearance="@style/toolbarStyle"
android:titleTextColor="@color/White"
android:layout_gravity="top"
app:titleEnabled="false" />
</FrameLayout>
