怎么用TableLayout布局方法在Button中添加图标？？ --------------------编程问答-------------------- 谢谢各位高手指点指点！！！ --------------------编程问答-------------------- Button.setXXXimg... --------------------编程问答-------------------- 要制作带图标的按钮，首先要在布局文件中定义ImageButton，然后通过SetImageDrawable方法设置按钮要显示的图标。按钮事件监听为SetOnClickListener。
  main.xml
   <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:orientation="vertical"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent"
     >
<TextView
     android:id="@+id/TextView01"
     android:layout_width="fill_parent"
     android:layout_height="wrap_content"
     />
   <ImageButton
   android:id="@+id/ImageButton01"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:src="@drawable/button1"
   >
   </ImageButton>
   <ImageButton
