Question

我有一个可搜索的微调器，其中包含首先手动输入的客户端列表。一切都运作良好。首先，我添加到gradle：compile'com.toptoche.searchablespinner：searchablespinnerlibrary：1.3.1' 然后我创建了一个fagment和一个布局来测试searcheable spinner，evrything工作。现在，我想通过json文件将一个客户端列表添加到我可搜索的微调器中。这是我的代码：

import android.os.AsyncTask;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Toast;
import com.android.volley.RequestQueue;
import com.android.volley.Response;
import com.android.volley.VolleyError;
import com.android.volley.toolbox.JsonArrayRequest;
import com.android.volley.toolbox.Volley;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;
import com.toptoche.searchablespinnerlibrary.SearchableSpinner;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import java.util.ArrayList;
import java.util.List;
public class FicheHypothese1 extends Fragment {

SearchableSpinner spinner;

String Url="http://10.0.2.1/ODBC_Connect_INDUS/GET_CLIENTS.php";
public static List<String> lst=null;
private AdView mAdView;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    new GetData().execute();
    spinner= (SearchableSpinner) findViewById(R.id.spinner);
    spinner.setTitle("Countries");
    mAdView = (AdView) findViewById(R.id.adView);
    AdRequest adRequest = new AdRequest.Builder()
            .build();
    mAdView.loadAd(adRequest);
}


 class GetData extends AsyncTask<String,String,String> {
    @Override
    protected void onPreExecute() {
        super.onPreExecute();
    }
    @Override
    protected void onPostExecute(String s) {
        super.onPostExecute(s);
    }
    @Override
    protected String doInBackground(String... params) {
        lst=new ArrayList<String>();
        JsonArrayRequest movieReq = new JsonArrayRequest(Url,
                new Response.Listener<JSONArray>()
                {
                    @Override
                    public void onResponse(JSONArray response) {
                        for(int i=0;i<response.length();i++){
                            try {
                                //Getting json object
                                JSONObject json = response.getJSONObject(i);
                                //Adding the name of the student to array list
                                lst.add(json.getString("CT_Intitule"));
                            } catch (JSONException e) {
                                e.printStackTrace();
                            }
                        }
                        ArrayAdapter adapter=new 
ArrayAdapter(getBaseContext(), 
R.layout.support_simple_spinner_dropdown_item, lst);
                        spinner.setAdapter(adapter);
                    }
                },
                new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                    }
                });
        //Creating a request queue
        RequestQueue requestQueue = 
Volley.newRequestQueue(getApplicationContext());
        //Adding request to the queue
        requestQueue.add(movieReq);
        return null;
    }

}

} 这是我的布局：

<com.toptoche.searchablespinnerlibrary.SearchableSpinner
    android:id="@+id/spinner"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
   />
 <com.google.android.gms.ads.AdView
     android:id="@+id/adView"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:layout_alignParentBottom="true"
     android:layout_alignParentLeft="true"
     android:layout_alignParentStart="true"
     android:layout_marginBottom="20dp"
     android:layout_alignParentRight="true"
     android:layout_alignParentEnd="true">
 </com.google.android.gms.ads.AdView>
</RelativeLayout>

我的应用已停止运行这是我的退出：
