根据此视频,我想从mysql获取详细信息以回收view。 android volley tutorial(json arrayrequest我写代码。但是表中的所有数据都在回收视图中显示。我想使用参数过滤数据。如何将参数传递给api.i使用php制作api
Background.java
public class BackgroundTask {
// DayPlanActivity dayPlanActivity=new DayPlanActivity();
Context contaxt;
ArrayList<gethourdetails> arrayList =new ArrayList<>();
public BackgroundTask(Context contaxt)
{
this.contaxt=contaxt;
}
public ArrayList<gethourdetails> getlist()
{
JsonArrayRequest jsonArrayRequest=new JsonArrayRequest(Request.Method.POST, Constants.GETDALYDETAILS_URL,null,
new Response.Listener<JSONArray>() {
@Override
public void onResponse(JSONArray response) {
int count=0;
while (count<response.length())
{
try {
JSONObject jsonObject=response.getJSONObject(count);
gethourdetails getdet=new gethourdetails(jsonObject.getString("hour_code"),jsonObject.getString("qrytime"),jsonObject.getString("hourqty"));
arrayList.add(getdet);
count++;
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(contaxt,"Error...",Toast.LENGTH_SHORT).show();
error.printStackTrace();
}
}
)
;
MySingleton.getInstance(contaxt).addToRequestque(jsonArrayRequest);
return arrayList;
}
}
gethourdetails.java

ContactAdapter

}
}
DayplanActivity.java
