显示api数据android studio java的图像

Question

所以，我从营养网站获得一些数据，我不能显示我得到的jgp，只有数据返回的名称。这是应用程序:app photo有办法显示jgp吗?
这是我用来从url获取数据的代码:
我对这个有点陌生，我不知道我应该在哪里修改我的代码。

package com.example.myapplication;

import androidx.appcompat.app.AppCompatActivity;
import androidx.appcompat.widget.Toolbar;

import android.os.AsyncTask;
import android.os.Bundle;
import android.util.Log;
import android.view.MenuItem;
import android.widget.ListAdapter;
import android.widget.ListView;
import android.widget.SimpleAdapter;
import android.widget.Toast;

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

import java.util.ArrayList;
import java.util.HashMap;

public class NutritionPlan1 extends AppCompatActivity {


private String TAG = MainActivity.class.getSimpleName();
private ListView lv;

ArrayList<HashMap<String, String>> resultList;

@Override
public boolean onOptionsItemSelected(MenuItem item) {

super.onOptionsItemSelected(item);
switch (item.getItemId()) {
case android.R.id.home:
finish();
break;
}
return true;
}

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_nutrition_plan1);



Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);


if (getSupportActionBar() != null){
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
}




resultList = new ArrayList<>();
lv = (ListView) findViewById(R.id.list);
new GetContacts().execute();
}



private class GetContacts extends AsyncTask<Void, Void, Void> {
@Override
protected void onPreExecute() {
super.onPreExecute();
Toast.makeText(NutritionPlan1.this,"Json Data is downloading",Toast.LENGTH_LONG).show();

}

@Override
protected Void doInBackground(Void... arg0) {
HttpHandler sh = new HttpHandler();
// Making a request to url and getting response
String url = "https://api.spoonacular.com/recipes/complexSearch?diet=vegetarian&apiKey=d22842b0ca9148839497a0022902ae97";

String jsonStr = sh.makeServiceCall(url);

Log.e(TAG, "Response from url: " + jsonStr);
if (jsonStr != null) {
try {
JSONObject jsonObj = new JSONObject(jsonStr);

// Getting JSON Array node
JSONArray results = jsonObj.getJSONArray("results");

// looping through All items
for (int i = 0; i < results.length(); i++) {
JSONObject c = results.getJSONObject(i);
String title = c.getString("title");

String image = c.getString("image");





// tmp hash map for single contact
HashMap<String, String> result = new HashMap<>();

// adding each child node to HashMap key => value
result.put("title", title);


result.put("image", image);


// adding contact to contact list
resultList.add(result);
}
} catch (final JSONException e) {
Log.e(TAG, "Json parsing error: " + e.getMessage());
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getApplicationContext(),
"Json parsing error: " + e.getMessage(),Toast.LENGTH_LONG).show();
}
});

}

} else {
Log.e(TAG, "Couldn't get json from server.");
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getApplicationContext(),
"Couldn't get json from server. Check LogCat for possible errors!",
Toast.LENGTH_LONG).show();
}
});
}

return null;
}

@Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
ListAdapter adapter = new SimpleAdapter(NutritionPlan1.this, resultList,
R.layout.list_nutrition_plans, new String[]{ "title","image"},
new int[]{R.id.title, R.id.image});
lv.setAdapter(adapter);
}
}
}

这是列表

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="@dimen/activity_horizontal_margin">

<TextView
android:id="@+id/title"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="@color/colorAccent"
android:text="Name:"/>

<ImageView
android:id="@+id/image"
android:layout_width="380dp"
android:layout_height="200dp"


/>

</LinearLayout>

你可以使用你的模型列表

modal可以有两个变量，比如imageUrl和title，然后你可以创建list

和每个模型添加到列表中，然后将该列表设置为适配器并呈现数据... .
