嘿伙计们我自己第一次尝试实现布局重量,有点我尝试使用线性布局它运行良好,但是当我尝试使用相对和线性布局时出现问题.你们可以告诉我这里有什么问题吗
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/Linearlayout" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:weightSum="100" > <RelativeLayout android:id="@+id/Rlayout" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="45" > <Gallery android:id="@+id/Gallery01" android:layout_width="fill_parent" android:layout_height="fill_parent" android:spacing="4dip" > </Gallery> </RelativeLayout> <RelativeLayout android:id="@+id/Rlayout1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="10" android:orientation="vertical" > <ImageView android:id="@+id/ImageView01" android:layout_width="fill_parent" android:layout_height="fill_parent" android:scaleType="fitXY" /> <ImageView android:id="@+id/ImageView02" android:layout_width="fill_parent" android:layout_height="fill_parent" android:scaleType="fitXY" /> </RelativeLayout> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/navbar" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="45" android:background="@drawable/button1" android:orientation="horizontal" android:weightSum="100" > <Button android:id="@+id/makerback" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center" android:layout_weight="20" android:background="@drawable/makerback" /> <Button android:id="@+id/makerphoto" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center" android:layout_weight="20" android:background="@drawable/makerphoto" /> <Button android:id="@+id/makerselves" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center" android:layout_weight="20" android:background="@drawable/makerselves" /> <Button android:id="@+id/makerskins" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center" android:layout_weight="20" android:background="@drawable/makerskins" /> <Button android:id="@+id/makersave" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center" android:layout_weight="20" android:background="@drawable/makersave" /> </LinearLayout> </LinearLayout>
我需要实现上面的图像
解决方法
You cannot use percentages to define the dimensions of a View inside a
RelativeLayout. The best ways to do it is to use LinearLayout and
weights,or a custom Layout.

Percentage width in a RelativeLayout
来自Docs:http://developer.android.com/reference/android/widget/LinearLayout.LayoutParams.html#weight
UPDATE
我们现在可以使用PercentRelativeLayout.来自docs的示例:
<android.support.percent.PercentRelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent"> <ImageView app:layout_widthPercent="50%" app:layout_heightPercent="50%" app:layout_marginTopPercent="25%" app:layout_marginLeftPercent="25%" /> </android.support.percent.PercentFrameLayout>
