为什么我的layout_weight不起作用?

问题描述

我有这个xml文件.我不明白为什么我第二个包含editText和callButton的linearlayout看起来不正确.看起来像这样(与电话的局部图片一致):

I have this xml file.I can't understand why my second linearlayout which contains editText and callButton isn't looking right. It looks like this (the line with the part picture of phone) :

在每个视图(editText和callButton)中，我都将layout_weights设置为1，所以电话图像应该占据屏幕的一半，对不对?这是我的代码.我希望两个视图都采用相同的宽度-输入文本时，editText不应拉伸，这是目前正在发生的情况.感谢您的帮助.

I have the layout_weights set to 1 in each of these views, editText and callButton, so the phone image should take up half the screen, right? Here's my code. I would like both views to take up the same width - and the editText shouldn't stretch when text is entered, as is currently happening. Thanks for any help.

推荐答案

将具有layout_width的EditText和Call按钮更改为"0dp"-

Change your EditText and Call button with layout_width to "0dp" -

<EditText

        android:layout_height="match_parent"
        android:id="@+id/editText"
        android:inputType="phone"
        android:gravity="center"
        android:background="#d9d9d9"
        android:layout_weight="1"

        />


        <ImageButton

            android:layout_height="match_parent"
            android:id="@+id/callButton"
            android:src="@drawable/call"
            android:clickable="true"
            android:onClick="softkeyboardButton"
            android:background="#ffa62b"
            android:layout_weight="1"

            />
