我不知道为什么togglebutton图像没有居中,有人能帮我吗?我觉得你的布局不错。我会尝试用另一个
ImageButton
替换ToggleButton
,以确保android不会像使用复选框那样自动添加一些填充。另外,请仔细检查player\u shuffle\u on
和player\u shuffle\u off
png是否被意外保存为透明填充
顺便说一下,不需要两个LinearLayout
,您只需要一个水平LinearLayout
作为根视图。将重心添加到第二个线性布局:
Add Gravity-Center to your second Linear Layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/LinearLayout01"

android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:id="@+id/controls"
android:layout_width="match_parent"
android:layout_height="35dp"
*android:gravity="center"*
android:background="@drawable/border" >
<ImageButton
