要在Android中实现平分屏幕的效果,可以使用GridLayout布局。以下是实现类似计算器界面效果的示例代码:
```xml
<GridLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:rowCount="4"
android:columnCount="4"
android:useDefaultMargins="true">
<Button
android:text="1"
android:layout_columnWeight="1"
android:layout_rowWeight="1" />
<Button
android:text="2"
android:layout_columnWeight="1"
android:layout_rowWeight="1" />
<Button
android:text="3"
android:layout_columnWeight="1"
android:layout_rowWeight="1" />
<Button
android:text="/"
android:layout_columnWeight="1"
android:layout_rowWeight="1" />
<Button
android:text="4"
android:layout_columnWeight="1"
android:layout_rowWeight="1" />
<Button
android:text="5"
android:layout_columnWeight="1"
android:layout_rowWeight="1" />
<Button
android:text="6"
android:layout_columnWeight="1"
android:layout_rowWeight="1" />
<Button
android:text="*"
android:layout_columnWeight="1"
android:layout_rowWeight="1" />
<Button
android:text="7"
android:layout_columnWeight="1"
android:layout_rowWeight="1" />
<Button
android:text="8"
android:layout_columnWeight="1"
android:layout_rowWeight="1" />
<Button
android:text="9"
android:layout_columnWeight="1"
android:layout_rowWeight="1" />
<Button
android:text="-"
android:layout_columnWeight="1"
android:layout_rowWeight="1" />
<Button
android:text="."
android:layout_columnWeight="1"
android:layout_rowWeight="1" />
<Button
android:text="0"
android:layout_columnWeight="1"
android:layout_rowWeight="1" />
<Button
android:text="="
android:layout_columnWeight="1"
android:layout_rowWeight="1" />
<Button
android:text="+"
android:layout_columnWeight="1"
android:layout_rowWeight="1" />
</GridLayout>
```
在这个示例中,我们使用了一个4x4的GridLayout,每个Button都设置了layout_columnWeight和layout_rowWeight属性为1,这将使每个元素在水平和垂直方向上平均分布,并且填满整个屏幕。
