Я хочу показать данные с моего сервера, но я не могу. Вот мой код Javaне может получить данные с сервера
public class AllProductsActivity extends ListActivity {
private ProgressDialog mProgressDialog;
JSONParser jparser = new JSONParser();
ArrayList<HashMap<String, String>> productlist;
private static String url = "http://localhost/android_connect/get_all_products.php";
private static final String TAG_SUCCESS = "success";
private static final String TAG_PRODUCTS = "products";
private static final String TAG_PID = "pid";
private static final String TAG_NAME = "name";
JSONArray product = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.all_product);
productlist = new ArrayList<HashMap<String, String>>();
new LoadAllProducts().execute();
ListView lv = getListView();
lv.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int postion, long id) {
String pid = ((TextView) view.findViewById(R.id.pid)).getText()
.toString();
Intent i = new Intent(getApplicationContext(),
EditProductActivity.class);
i.putExtra(TAG_PID, pid);
startActivityForResult(i, 100);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == 100) {
Intent intent = getIntent();
finish();
startActivity(intent);
}
}
class LoadAllProducts extends AsyncTask<String, String, String> {
@Override
protected void onPreExecute() {
super.onPreExecute();
mProgressDialog = new ProgressDialog(AllProductsActivity.this);
mProgressDialog.setTitle("Loading");
mProgressDialog.setMessage("Please Wait");
mProgressDialog.setIndeterminate(false);
mProgressDialog.setCancelable(false);
mProgressDialog.show();
}
@Override
protected String doInBackground(String... args) {
List<NameValuePair> params = new ArrayList<NameValuePair>();
JSONObject json = jparser.makeHttpRequset(url, "GET", params);
Log.d("All Product:", json.toString());
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
product = json.getJSONArray(TAG_PRODUCTS);
for (int i = 0; i < product.length(); i++) {
JSONObject c = product.getJSONObject(i);
String id = c.getString(TAG_PID);
String name = c.getString(TAG_NAME);
HashMap<String, String> map = new HashMap<String, String>();
map.put(TAG_PID, id);
map.put(TAG_NAME, name);
productlist.add(map);
}
} else {
Intent i = new Intent(getApplicationContext(),
NewProductActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(i);
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
protected void onPostExecute(String file_url) {
mProgressDialog.dismiss();
runOnUiThread(new Runnable() {
@Override
public void run() {
ListAdapter adapter = new SimpleAdapter(
AllProductsActivity.this, productlist,
R.layout.list_item, new String[] { TAG_PID,
TAG_NAME },
new int[] { R.id.pid, R.id.name });
setListAdapter(adapter);
}
});
enter code here
}
}
}
и это мой LogCat

Это все ваши LogCat? Больше ничего нет? –
да, что все ... –
@RickyAdithya Почему вы вводите «введите код здесь» в свой код/вопрос или это часть фактического кода, о котором я очень сомневаюсь. –
