1、XML方式
- <Button android:drawableLeft="@drawable/btn_strip_mark_on"></Button>
2、JAVA代码
- Drawable img_on, img_off;
- Resources res = getResources();
- img_off = res.getDrawable(R.drawable.btn_strip_mark_off);
- // 调用setCompoundDrawables时,必须调用Drawable.setBounds()方法,否则图片不显示
- img_off.setBounds(0, 0, img_off.getMinimumWidth(), img_off.getMinimumHeight());
- btn.setCompoundDrawables(img_off, null, null, null); //设置左图标
