你好，我正在做一个大学项目，我需要一些指导
我正在尝试在表格视图中显示 JSON 数据
JSON:: http://54.218.73.244:7000/
MainActivity.java
public class MainActivity extends Activity {
// url to make request
private static String url = "http://54.218.73.244:7000/";
List<Item> yourData = new ArrayList<Item>();
ProgressDialog progressDialog;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Instantiating ProgressDialog with onCreate method
progressDialog=new ProgressDialog(MainActivity.this);
new ParsingAsync().execute();
}
private class ParsingAsync extends AsyncTask<Void, Void, Void>
{
@Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
progressDialog=ProgressDialog.show(MainActivity.this, "", "Please Wait", true, false);
}
@Override
protected Void doInBackground(Void... params) {
// TODO Auto-generated method stub
// Creating JSON Parser instance
JSONObjParser jParser = new JSONObjParser();
// getting JSON string from URL
JSONArray json = jParser.getJSONFromUrl(url);
try {
for (int i = 0; i < json.length(); i++) {
JSONObject c = json.getJSONObject(i);
// Storing each json item in variable
String NAME=c.getString("restaurantNAME");
yourData.add(new Item(NAME));
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Void result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
progressDialog.dismiss();
ListView yourListView = (ListView) findViewById(R.id.listViewID);
ListAdapter customAdapter = new ListAdapter(MainActivity.this, R.layout.itemlistrow, yourData);
yourListView.setAdapter(customAdapter);
yourListView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
if(position == 0)
{
//code specific to first list item
Intent myIntent = new Intent(MainActivity.this,CopperChimneyDesc.class);
startActivity(myIntent);
}else if(position == 1)
{
Intent myIntent = new Intent(MainActivity.this,AroyDesc.class);
startActivity(myIntent);
}
}
});
}
}
}
CopperChimney_desc_screen.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<Button
android:id="@+id/button1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="5sp"
android:text="BACK" />
</LinearLayout>
- 虽然我已经能够实现将 JSON 数据填充到 textview 和 listview
- 如何从上面的 URL 显示 JSON 到表格视图
