如何删除“CardView”android的额外填充

标签: android android-cardview

我的布局中有一个CardView,宽度为match_parent。当我在我的Marshmallow测试设备中运行应用程序时,它的工作完美。但是在我的Jellybean设备中,它显示了一些填充。

我试过

app:cardPreventCornerOverlap="false" app:cardUseCompatPadding="false" android:hardwareAccelerated="true"

但它不起作用。

清单:

    <application
        android:name=".activities.ThisApplication"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".activities.HomeActivity">

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>

        <activity

            android:windowSoftInputMode="stateAlwaysHidden" />
        <activity

            android:label="@string/title_activity_transaction"
            android:theme="@style/AppTheme"></activity>
    </application>
</manifest>

您为所有设备和平板电脑使用了一个库来管理ui设计。

在gradle文件中添加以下依赖项...

compile 'com.intuit.sdp:sdp-android:1.0.4'

然后在以下代码方式定义任何填充,边距之后..

        android:padding="@dimen/_20sdp"
        android:layout_marginTop="@dimen/_5sdp"
