问题描述
我的底部布局包含三个图像.我希望它们被平均分配.为此,我使用了layout_weight
xml属性.但是它们的视觉表现很糟糕–图像都被拉伸了
I have a bottom layout with three images. I want them to be equally distributed. To do this, I used the layout_weight
xml property. But the visual representation of them is awful – the images are all stretched out
图像尺寸为32 * 32.
The images' dimension is 32*32.
此特定工具栏的布局代码为:
The layout code for this particular toolbar is:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/toolbar_bottom"
xmlns:appo="http://schemas.android.com/apk/res-auto"
android:minHeight="50dp"
android:background="#ffff8c0e"
appo:theme="@style/ToolbarTheme"
android:minWidth="50dp"
android:elevation="10dp"
>
<LinearLayout
android:id="@+id/toolbarmenucontainer"
android:layout_width="match_parent"
android:weightSum="3"
android:layout_height="match_parent"
android:orientation="horizontal" >
<ImageView
android:layout_width="0dp"
android:id="@+id/camera_image"
android:layout_height="wrap_content"
android:layout_weight="1"
android:clickable="true"
android:scaleType="fitXY"
android:src="@drawable/camera_icon"
/>
<ImageView
android:id="@+id/news_image"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:clickable="true"
android:scaleType="fitXY"
android:layout_weight = "1"
android:src="@drawable/new_icon"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<ImageView
android:id="@+id/facebook_image"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:clickable="true"
android:scaleType="fitXY"
android:src="@drawable/facebooc_image"
/>
</LinearLayout>
如何使它们正确显示?
推荐答案
将ImageView
包装在另一个布局中,例如RelativeLayout
.
wrap ImageView
in another layout say RelativeLayout
.
即做这样的事情.
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:appo="http://schemas.android.com/apk/res-auto"
android:id="@+id/toolbar_bottom"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ffff8c0e"
android:elevation="10dp"
android:minHeight="50dp"
android:minWidth="50dp"
appo:theme="@style/ToolbarTheme" >
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/toolbarmenucontainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:weightSum="3" >
<RelativeLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1" >
<ImageView
android:id="@+id/camera_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:clickable="true"
android:scaleType="fitXY"
android:src="@drawable/camera_icon" />
</RelativeLayout>
<RelativeLayout

android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerInParent="true"

android:scaleType="fitXY"
android:src="@drawable/new_icon" />
