Answer 1

您可能正在查看与手机屏幕尺寸不同的设备的预览。

要在所有设备中将图像均分为3个部分，请使用GridView / GridLayout或使用带权重的LinearLayout。

Answer 2

试试这个：

<?xml version="1.0" encoding="utf-8"?>

    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1"
    android:orientation="horizontal"
    android:weightSum="3" >

    <ImageButton
        android:layout_width="0dp"
        android:layout_height="fill_parent"
        android:layout_weight="1"
