将图像添加到按钮

Question

我有一个可以播放数字的幻灯片，现在我希望能够选择使用图片。我的图片是在imageBoard，我不知道如何使它工作。一切都需要在同一个班级。

public void onCreate(Bundle savedInstanceStat) {
    super.onCreate(savedInstanceStat);
    board = new Board();
    board.shuffleBoard();
    updateTileText();
}

在layout.xml中

   <ImageButton
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:id="@+id/button1"
      android:src="@drawable/abc"/>

Answer 3

在按钮上使用setBackgroundResource()并传递按钮上的drawable id，为其指定背景。
