当我已经用完了样式和背景的选项时,如何在android xml中应用按钮的状态按下?_Android_Xml - Fatal编程技术网

当我已经用完了样式和背景的选项时,如何在android xml中应用按钮的状态按下?

当我已经用完了样式和背景的选项时,如何在android xml中应用按钮的状态按下?,android,xml,Android,Xml,我有一个num键盘,我用按钮创建,并隐藏了我的android软键盘 这就是我的每个按钮对于不同数字的外观 <Button android:id="@+id/seven" android:text="7" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1"

我有一个num键盘,我用按钮创建,并隐藏了我的android软键盘

这就是我的每个按钮对于不同数字的外观

 <Button
        android:id="@+id/seven"
        android:text="7"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        style="@style/CustomStyle"
        android:background="@drawable/gridlayout_border"
 />

请注意,我使用的是CustomStyle,其代码如下所示,文件名为button\u style.xml

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">
    <style name="CustomStyle">
        <item name="android:textSize">24dp </item>
        <item name="android:textColor">#fdfdfd</item>
        <item name="android:textStyle">bold </item>
        <item name="android:padding">20dp</item>
    </style>

</resources>
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:left="-10dp" android:right="0dp"  android:top="-10dp"
        >
        <shape android:shape="rectangle">
            <!--apply button background transparent, full opacity-->
            <solid android:color="#00ffffff"/>
            <stroke android:color="#ffffff" android:width="2dp"/>
        </shape>
    </item>
</layer-list>

24dp
#fdfdfd
大胆的
20dp
另外,我使用gridlayout_边框作为背景 gridlayout\u border.xml

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">
    <style name="CustomStyle">
        <item name="android:textSize">24dp </item>
        <item name="android:textColor">#fdfdfd</item>
        <item name="android:textStyle">bold </item>
        <item name="android:padding">20dp</item>
    </style>

</resources>
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:left="-10dp" android:right="0dp"  android:top="-10dp"
        >
        <shape android:shape="rectangle">
            <!--apply button background transparent, full opacity-->
            <solid android:color="#00ffffff"/>
            <stroke android:color="#ffffff" android:width="2dp"/>
        </shape>
    </item>
</layer-list>

从那时起,我已经用完了按钮中的样式和背景标记。当按下num键盘上的按钮时,如何再应用一种样式/颜色


提前感谢

您可以使用选择器确定视图的不同状态。大概是这样的:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true">
    <!-- Write your focused state code-->
</item>
<item android:state_pressed="true">
    <!-- Write your pressed state code-->
</item>
<item>
    <layer-list>
        <item android:left="-10dp" android:right="0dp" android:top="-10dp"
            >
            <shape android:shape="rectangle">
                <!--apply button background transparent, full opacity-->
                <solid android:color="#00ffffff"/>
                <stroke android:width="2dp" android:color="#ffffff"/>
            </shape>
        </item>
    </layer-list>
