Question

怎么判断volley多次请求完成

Answer 1

int frequency;
String errorStr;

for (int i = 0; i < 5; i++) {
StringRequest request = new StringRequest(url, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
postMessage();
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
postMessage();
errorStr = errorStr + erreor.getMessage();
}
});
VolleyController.addToRequestQueue(request, mContext.getApplicationContext());
}

private void postMessage(){
frequency++；
if(frequency == 5){
发送一条广播，弹出errorStr错误，如果errorStr不为空则全部执行成功
}
