Question

正如标题所说，我在缩放Scrollview时遇到问题。

滚动视图包含多个按钮。我在看起来不错的Google Pixel 3 XL上测试了我的应用程序，但在Pixel 2上看起来太大了，某些按钮无法访问，因为导航栏将它们悬停了。

这是我的XML代码：

const char* function1()
{
    lang = fopen("lang.csv", "r");
    int i = 0;
    char line[1024];
    const char* word[1024];
    char num[] = { 1 , 2 };
    while (fgets(line, 1024, lang))
    {
        char* tmp = _strdup(line);
        printf("Field 1 would be %s\n", getfield(tmp, num[0])); // NOTE strtok clobbers tmp
        word[i] = getfield(tmp, num[0]);
        i++; 
        free(tmp);
    }
    printf("%s\n", word[1]); //prints successfully
    fclose(lang);
    return NULL;
}

int function2() {
    const char* word[1024] = { function1() };
    printf("%s\n", word[1]); // failure, prints (null)
}

尝试在项目中添加尺寸值，并为每个对象提供适当的填充，无论它是按钮，文本还是其他任何东西。

创建一个dimens.xml文件夹并添加它，然后根据需要添加这些值
