android - android ListView 中的异常

Question

我在 ListView 中添加了标题在过去向上或向下滚动时抛出异常这是通过自定义 View 列表解决的:

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

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

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

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


@Override
protected void dispatchDraw(Canvas canvas) {
    try {
        super.dispatchDraw(canvas);
    } catch (IndexOutOfBoundsException e) {
        e.printStackTrace();
    }

}

但是现在Android 6.0.1(marshmallow)，再次显示是以前的错误:在我的堆栈跟踪中:

java.lang.IndexOutOfBoundsException: Invalid index 0, size is 0 : at java.util.ArrayList.throwIndexOutOfBoundsException(ArrayList.java:255)

添加标题:

private void Create_Header_Sjd_init() {

    LayoutInflater  inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
    convertViewHeader = inflater.inflate(R.layout.row_idea_list , null);
    convertViewHeader.setBackgroundColor(getResources().getColor(R.color.gray_light_light));

    listView.addHeaderView(convertViewHeader, null, false);
}

Answer 1

通过子代码解决这个错误:

        listView.setFooterDividersEnabled(false);
    listView.addFooterView(new View(this), null, false);
