尝试为LinearLayout中的任何屏幕均匀地间隔按钮，而不拉伸图像

Question

I gave the answer in this question a try, the only difference being that I'm using a vertical LinearLayout instead of horizontal:

Children in Linear Layout with equal padding

As such, I figured that I would swap around the width/height attributes so that width for all elements would be wrap_content, where as height would be match_parent. Is that how it should be?

Anyway, my weight selection is still causing my buttons to stretch in horrible ways.

Here is the xml file:

   <LinearLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center_horizontal"
        android:orientation="vertical"
        tools:context=".MainActivity" >

        <ImageView
            android:id="@+id/logo"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:scaleX="0.8"
            android:scaleY="0.8"
            android:src="@drawable/logo" />

        <Button
            android:id="@+id/button1"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_weight="0.4"
            android:background="@drawable/button1_image"
            android:onClick="button1" />

        <Button
            android:id="@+id/button2"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_weight="0.4"
            android:background="@drawable/button2_image"
            android:onClick="button2" />

        <Button
            android:id="@+id/button3"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="0.4"
            android:background="@drawable/button3_image"
            android:onClick="button3" />

        <Button
            android:id="@+id/button4"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_weight="0.4"
            android:background="@drawable/button4_image"
            android:onClick="button4" />

        <Button
            android:id="@+id/button5"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_weight="0.4"
            android:onClick="Button5"
            android:text="Text"
            android:textSize="26dp" />
    </LinearLayout>

I feel like I'm close - what am I missing here?

Answer 1

If you want to prevent an item from being stretched, set it's height and width attributes to

android:layout_width="wrap_content"
android:layout_height="wrap_content"

So the buttons will only be as wide as the background image given.

If your background image is too large, that can be skewing things as well.

i don't know excetly what you require, but is this helpful to you?

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

        android:scaleX="0.8"
        android:scaleY="0.8"

</LinearLayout>
