1. 自定义ActionMenuView，重写onMeasure方法，将溢出按钮的宽度设为0，防止与其他操作图标重叠。示例代码如下：

public class CustomActionMenuView extends ActionMenuView {

public CustomActionMenuView(Context context) {
    super(context);
}

public CustomActionMenuView(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public CustomActionMenuView(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    int width = MeasureSpec.getSize(widthMeasureSpec);
    int height = MeasureSpec.getSize(heightMeasureSpec);
    int overflowWidth = getChildAt(getChildCount()-1).getMeasuredWidth();
    setMeasuredDimension(width - overflowWidth, height);
}

}

2. 在布局文件中使用自定义的ActionMenuView，示例代码如下：

3. 如果想要在溢出菜单中显示图标，可以使用setOverflowIcon方法设置溢出图标，示例代码如下：

actionMenuView.setOverflowIcon(ContextCompat.getDrawable(this, R.drawable.ic_overflow));
