setContentView(R.layout.main);
Integer[] mButtonState = {R.drawable.defaultbutton,
R.drawable.focusedpressed, R.drawable.pressed};

MyButton myButton = new MyButton(this);
mButton.setBackgroundDrawable(myButton.setbg(mButtonState));
}

//以下这个方法也可以把你的图片数组传过来，以StateListDrawable来设置图片状态，来表现button的各中状态。未选中，按下，选中效果。
public StateListDrawable setbg(Integer[]mImageIds) {
StateListDrawable bg = newStateListDrawable();
Drawable normal =this.getResources().getDrawable(mImageIds);
Drawable selected =this.getResources().getDrawable(mImageIds);
Drawable pressed =this.getResources().getDrawable(mImageIds);
bg.addState(View.PRESSED_ENABLED_STATE_SET,pressed);
bg.addState(View.ENABLED_FOCUSED_STATE_SET,selected);
bg.addState(View.ENABLED_STATE_SET,normal);
bg.addState(View.FOCUSED_STATE_SET,selected);
bg.addState(View.EMPTY_STATE_SET, normal);
return bg;
