因为当我插入,删除,更新数据时,数据列表尚未更新。修改数据后,请帮助刷新缓存,以便显示列表也将在修改后更新。
我的CacheInterceptor:
#include <stdio.h>
long double factorial(long double n,long double base = 1){
if (n <= 1){
return 1*base;
}else{
return factorial(n-1,n * base);
}
}
int main(){
printf("%.0Lf\n",factorial(25)); // this result is correct
printf("%.0Lf\n",factorial(26));
//correct result is 403291461126605635584000000,but it return 403291461126605635592388608
return 0;
}
显示数据:
public Response intercept(Chain chain) throws IOException
{
Response originalResponse = chain.proceed(chain.request());
if ( Utils.isNetworkAvailable(context) )
{
int maxAge = 60; // read from cache for 1 minute
return originalResponse.newBuilder()
.header("Cache-Control", "public, max-age=" + maxAge)
.build();
}
else
{
int maxStale = 60 * 60 * 24 * 28; // tolerate 4-weeks stale
return originalResponse.newBuilder()
.header("Cache-Control", "public, only-if-cached, max-stale=" + maxStale)
.build();
}
插入数据:
for(Result result : commitment.getResultlist())
{
Log.e("id", String.valueOf(result.getId()) );
Log.e("Title", result.getTitle());
Log.e("Description", result.getDescription());
textResult.append(String.valueOf(result.getId()) + " ,");
textResult.append(result.getTitle());
textResult.append(", " + result.getDescription() + "\n\n");
