我做了一個RecyclerView的佈局,其中每個項目都是一個ImageView,下面有一個TextView,下面有一個形狀來爲項目添加邊框。縮放問題RecyclerView項目
問題是,在縱向方向上,圖像不適合整個空間,而在橫向進行。
activity.xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/coordlayout" >
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/appbarlayout">
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/collapsingtoolbar"
app:layout_scrollFlags="scroll|enterAlways">
<include
layout="@layout/toolbar"
android:id="@+id/toolbar"
app:layout_scrollFlags="scroll|enterAlways" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:id="@+id/recyclerview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/appbarlayout"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
</android.support.v7.widget.RecyclerView>
</android.support.design.widget.CoordinatorLayout>
recyclerview_item.xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.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:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="5dp" >
<ImageView
android:id="@+id/flIcon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="@string/freelancer_s_portrait"
android:background="@drawable/menu_square"
app:srcCompat="@drawable/rampart_pt"
android:padding="3dp"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="@+id/flName"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/menu_square"
android:gravity="center"
android:text="Asana"
android:textAppearance="@android:style/TextAppearance.DeviceDefault.Medium.Inverse"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toBottomOf="@+id/flIcon" />
</android.support.constraint.ConstraintLayout>
我該如何解決?
你知道爲什麼視圖不只是調整其高度,所以圖像不需要拉伸,而是? –
