ListView中的最后一个图像在我向下滚动（随机）之前不会显示

Question

我正在使用React Native的#include <stdio.h> #include <stdlib.h> #include <string.h> typedef struct { char ChannelNo[2]; // "P1" unsigned int ChannelPin; // 23 char State; // 'o' } test; typedef struct { test One[2]; test two[2]; test three[2]; test four[2]; test five; test six[1]; } matrix; matrix matrix1[] = {{ {{{"P4",2,'O'},{"P4",1,'O'},{"Z",0,'Z'}}, {{"P4",4,'O'},{"P4",3,'O'},{"P4",5,'O'}}, {{"0",0,'0'},{"0",0,'0'},{"0",0,'0'}}, {{"0",0,'0'},{"0",0,'0'},{"0",0,'0'}}, {{"0",0,'0'}}, {{"P1",49,'S'},{"P1",1,'G'}} }, { {{"P4",2,'O'},{"P4",1,'O'},{"Z",0,'Z'}}, {{"P4",4,'O'},{"P4",3,'O'},{"P4",5,'O'}}, {{"0",0,'0'},{"0",0,'0'},{"0",0,'0'}}, {{"0",0,'0'},{"0",0,'0'},{"0",0,'0'}}, {{"0",0,'0'}}, {{"P1",49,'S'},{"P1",1,'G'}} } } int main() { printf("%d\n",matrix1[1].One[0].ChannelPin); return 0; } 来显示每行3张图像，就像Instagram一样。但是，最后一行的最后一张图片，由于屏幕高度限制而最初显示为一半，有时在我向下滚动之前无法显示。

如何解决此问题？猫图像每张不到20KB，它通过Expo App在iPhone 7 Plus上运行，因此内存应该不是问题。
