好吧,首先请确保将依赖项包括在
build.grade(Module: app)
在您的android应用中.
Well, first make sure to include the dependency at
build.grade(Module: app)
in your android app.
dependencies {
compile 'com.android.support:percent:23.3.0'
}
然后在此示例(.MainActivity)中导航到您的xml布局
Then navigate to your xml layout in this example (.MainActivity)
<android.support.percent.PercentRelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity">
<Button
android:id="@+id/button"
android:text="Button"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
app:layout_widthPercent="30%"/>
<Button
android:id="@+id/button2"
android:text="Button 2"
