请问调用LISTVIEW_AddRow后死机是这么回事呢？

tovax · 发表于 2018-8-13 23:49:35

在主界面添加LISTVIEW，添加Column没问题，但是一添加Row（LISTVIEW_AddRow）就死机了；
搜了一下，遇到类似问题还挺多的，但是没有一个确切的解决方案，请问是什么原因呢？
GUI_Conf.h中我设置的10MB外部SDRAM做动态内存，应该够了吧，不知道这个LISTVIEW受什么影响比较大呢？

方便的话，可以贴一个稍完整的测试代码，我测试下看下。

以下代码，不管使用GUI_Font24_ASCII字体，还是SIF字体，只要调用LISTVIEW_AddRow就出问题了；屏蔽掉三行LISTVIEW_AddRow就可以正常显示了：
这代码是用ucguibuilder生成的，没做任何修改；电脑系统是windows10 64bit。

这里说“LISTVIEW_AddRow(_hListView, (GUI_ConstString *)_aTable_1);”，试过了，也不行。

这个是ucgui3.98自带的例程，测试后发现例程是可以正常运行的：

ucguibuilder生成的代码，不包含LISTVIEW_AddRow的代码段记为“代码段A”，包含LISTVIEW_AddRow的代码段记为“代码段B”；
ucgui3.98自带的例程记为“代码段C”；
测试步骤：
1. 代码段A ---> OK (注：代码段A屏蔽了LISTVIEW_AddRow函数)
2. 代码段B ---> NG
3. 代码段A ---> NG (注：经过代码段B的测试后，再测试代码段A就不行了)
4. 代码段C ---> OK (注：代码段C是UCGUI3.98自带的Sample里的WIDGET_ListView.c)
5. 代码段A ---> OK (注：代码段C有恢复OK的能力)
以上测试过程说明：本来代码段A是功能正常的，但是烧录代码段B导致死机后，重新烧录代码段A也一样死机，只有烧录一下代码段C才能使代码段A重新恢复正常功能，而代码段B不管怎么样都会死机。

代码段B死机的问题还是没有对比出有什么异常，代码段C为什么能恢复死机功能也成了谜了。。。

（每次烧录后都有重新上电的）

十分感谢！这个显示结果跟模拟器是一样的，不过都跟设计本意不一样，ucguibuilder中是这样的：
C1 C2 C3 C4 C5 C6
R1 111 222 333
R2
R3
LISTVIEW_AddRow造成死机的问题，我再对比两段代码看看，有结果再来回复。

测试结果总结：

1. Column的数量是添加Row的参考基数，如下，有6个Column的话，Row的字符串数组必须是6个，即便是“空”，也要占用一个字符串地址：
static const char * _lvTable_00[6] ={"R1" , "111" , "222" , "333" , "444" , "555"};
static const char * _lvTable_01[6] ={"" , "" , "" , "" , "" , ""};
static const char * _lvTable_02[6] ={"R3" , "111" , "222" , "333" , "444" , "555"};

2. 以上结果由eric2013的测试得出的结论，又按这个思路看了LISTVIEW_AddRow的源码，但是没有仔细分析，应该是这个原因，以下是ucgui源码：

for (i = 0; i < NumColumns; i++) {
LISTVIEW_CELL* pCell;
s = (ppText) ? *ppText++ : 0;
if (s == 0) {
ppText = 0;
}
NumBytes = GUI__strlen(s) + 1; /* 0 if no string is specified (s == NULL) */
if (GUI_ARRAY_AddItem(&pRow->CellArray, NULL, sizeof(LISTVIEW_CELL) + NumBytes)) {
r = 1;
break;
}
pObj = LISTVIEW_H2P(hObj); /* Restore after allocating memory */
pRow = (LISTVIEW_ROW*) GUI_ARRAY_GetpItem(&pObj->RowArray, RowIndex); /* Restore after allocating memory */
pCell = (LISTVIEW_CELL*) GUI_ARRAY_GetpItem(&pRow->CellArray, i);
if (NumBytes > 1) {
strcpy(pCell->acText, s);
}
}

复制代码

3. 昨天同样的代码，我这边死机，而eric2013那边可以正常显示，原因可能是编译器不同，我用的编译器是arm-none-eabi-gcc

4. 这个问题暂时这样了，后续有空再仔细分析，有兴趣深入分析的朋友欢迎交流！
