来自xml选择器的填充图像 [英] padding image from xml selector

问题描述

我正在尝试将主菜单的按钮背景图像填充(我在使用用于不同状态的选择器)，以这种方式进行(buttoninicio_custom.xml):

I'm trying to padd my button background image of my main menu (I'm using a selector for the different states), doing it on this way (buttoninicio_custom.xml):

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/botoninicial_pressed"
          android:state_pressed="true">

            <padding
            android:left="10dp"
            android:top="10dp"
            android:right="10dp"
            android:bottom="10dp" />

    </item>
    <item android:drawable="@drawable/botoninicial_pressed"
          android:state_focused="true">

            <padding
            android:left="10dp"
            android:top="10dp"
            android:right="10dp"
            android:bottom="10dp" />

    </item>
    <item android:drawable="@drawable/botoninicial">
            <padding
            android:left="10dp"
            android:top="10dp"
            android:right="10dp"
            android:bottom="10dp" />
    </item>
</selector>

..但是填充无效.我应该怎么解决这个问题?

..but the padding has no effect. What I should do to solve this problem??

我已经在每个"item"标签内部使用了"bitmap"标签，并在其中添加了填充，但是它仍然在做任何事情！！！

I already used "bitmap" tag inside each "item" tag with the padding inside, but it's still doing anything!!!

我的主按钮看起来像这样:

My main button looks this way:

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center_horizontal"
    android:orientation="horizontal" >

    <Button
        android:id="@+id/button2"
        android:layout_width="180dp"
        android:layout_height="50dp"
        android:layout_marginBottom="15dp"
        android:textSize="16sp"
        android:textColor="#FFFFFF"
        android:background="@drawable/buttoninicio_custom"
        android:text="@string/idmMENU2" />
</LinearLayout>

因为如果我在"button"标签内设置了android:padding，它将填充文本而不是背景图像...问题是当我按下主按钮时:我的图像背景正确更改，但是新图像出现剪裁."

"Because if I set android:padding inside the "button" tag, it pads me the text not the background image... The problem it's that when I pressed the main button: My image background change correctly but the new image appear cut."

推荐答案

将其包装在layer-list中:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:bottom="3dp"
        android:left="3dp"
        android:right="3dp"
        android:top="1dp">

        <selector xmlns:android="http://schemas.android.com/apk/res/android">
            <!-- your original selector content -->
        </selector>
    </item>
</layer-list>
