Solution 1:
how to show listview itemclick image into the alertbox using android json?
onItemClick use position to get clicked row HashMap from arraylist :
HashMap<String, String> map =arraylist.get(position);
Get clicked row name and image URL from map and show it in AlertDialog as doing in getView() method of ListViewAdapter
Solution 2:
public class SubMenu extends AppCompatActivity {
JSONObject jsonobject;
JSONArray jsonarray;
ListView listview;
ListViewAdapter adapter;
ProgressDialog mProgressDialog;
ArrayList<HashMap<String, String>> arraylist;
static String RANK = "id";
static String COUNTRY = "name";
static String FLAG = "image";
Integer i = 1;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sub_menu);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
String SelectedId = getIntent().getStringExtra("id");
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
// Get the view from listview_main.xml
// Execute DownloadJSON AsyncTask
new DownloadJSON().execute();
}
// DownloadJSON AsyncTask
private class DownloadJSON extends AsyncTask<Void, Void, Void> implements AdapterView.OnItemClickListener {
// @Override
// protected void onPreExecute() {
// super.onPreExecute();
// Create a progressdialog
// mProgressDialog = new ProgressDialog(SubMenu.this);
// Set progressdialog title
// mProgressDialog.setTitle("Categories of Main categories.....");
// Set progressdialog message
// mProgressDialog.setMessage("Loading...");
// mProgressDialog.setIndeterminate(false);
// Show progressdialog
// mProgressDialog.show();
// }
@Override
protected Void doInBackground(Void... params) {
// Create an array
arraylist = new ArrayList<HashMap<String, String>>();
// Retrieve JSON Objects from the given URL address
jsonarray = JsonFunctions
.getJSONfromURL("http://cloud.granddubai.com/broccoli/menu_typeitem.php?id=" + getIntent().getStringExtra("id"));
try {
// Locate the array name in JSON
// jsonarray = jsonobject.getJSONArray("main_menu_items");
for (int i = 0; i < jsonarray.length(); i++) {
HashMap<String, String> map = new HashMap<String, String>();
jsonobject = jsonarray.getJSONObject(i);
// Retrive JSON Objects
// map.put("id", jsonobject.getString("id"));
map.put("name", jsonobject.getString("name"));
map.put("image", jsonobject.getString("image"));
// Set the JSON Objects into the array
arraylist.add(map);
}
} catch (JSONException e) {
Log.e("Error", e.getMessage());
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Void args) {
// Locate the listview in listview_main.xml
listview = (ListView) findViewById(R.id.list1);
// Pass the results into ListViewAdapter.java
adapter = new ListViewAdapter(SubMenu.this, arraylist);
// Set the adapter to the ListView
listview.setAdapter(adapter);
listview.setOnItemClickListener(this);
// Close the progressdialog
// mProgressDialog.dismiss();
}
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long rowId) {
final AlertDialog customDialog = new AlertDialog.Builder(SubMenu.this).create();
final LayoutInflater inflater = getLayoutInflater();
final View dialogView = inflater.inflate(R.layout.popup
, null);
customDialog.setView(dialogView);
// set the custom customDialogimation components - text, image and button
final TextView tvDistance = (TextView) dialogView.findViewById(R.id.h2);
ImageLoader imageLoader= new ImageLoader(dialogView.getContext());
final ImageView desimage = (ImageView) dialogView.findViewById(R.id.desimage);
imageLoader.DisplayImage(arraylist.get(position).get("image"), desimage);
// crust.setOnItemSelectedListener(this);
// public void addListenerOnSpinnerItemSelection() {
final Button ok = (Button) dialogView.findViewById(R.id.ok);
ok.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
customDialog.dismiss();
}
});
final Button cncl = (Button) dialogView.findViewById(R.id.canc);
cncl.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
customDialog.dismiss();
}
});
Button _decrease = (Button) dialogView.findViewById(R.id.incr);
Button _increase = (Button) dialogView.findViewById(R.id.decr);
Spinner spinner1 = (Spinner) dialogView.findViewById(R.id.crust);
Spinner spinner2 = (Spinner) dialogView.findViewById(R.id.adson);
ArrayList<String> alspinner1 = new ArrayList<>();
ArrayList<String> alspinner2 = new ArrayList<>();
/**
* @purpose Array list to show the questions in spinner
*/
final String[] _spvalue1 = getResources().getStringArray(R.array.Crust_array);
final String[] _spvalue2 = getResources().getStringArray(R.array.AddsOn_array);
for (int i = 0; i < _spvalue1.length; i++) {
alspinner1.add(_spvalue1[i]);
}
for (int i = 0; i < _spvalue2.length; i++) {
alspinner2.add(_spvalue2[i]);
}
ArrayAdapter<String> adapter1 = new ArrayAdapter<>(dialogView.getContext(), android.R.layout.simple_spinner_item, alspinner1);
ArrayAdapter<String> adapter2 = new ArrayAdapter<>(getApplicationContext(), android.R.layout.simple_spinner_item, alspinner2);
adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
adapter2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner1.setAdapter(adapter1);
spinner2.setAdapter(adapter2);
final TextView _value = (TextView) dialogView.findViewById(R.id.value);
i = Integer.parseInt(_value.getText().toString());
_decrease.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
String _stringVal;
Log.d("src", "Decreasing value...");
if (i > 0) {
i = i - 1;
_stringVal = String.valueOf(i);
_value.setText(_stringVal);
} else {
Log.d("src", "Value can't be less than 0");
}
}
});
_increase.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String _stringVal;
Log.d("src", "Increasing value...");
i = i + 1;
_stringVal = String.valueOf(i);
_value.setText(_stringVal);
}
});
customDialog.show();
}
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
onBackPressed();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}
It's the solution. Try this.
Solution 3:
hi i gt the solution here:
public void onItemClick(AdapterView<?> parent, View view,
int position, long rowId) {
final AlertDialog customDialog = new AlertDialog.Builder(SubMenu.this).create();
final LayoutInflater inflater = getLayoutInflater();
final View dialogView = inflater.inflate(R.layout.popup
, null);
customDialog.setView(dialogView);
HashMap<String, String> map =arraylist.get(position);
ImageView image = (ImageView) dialogView.findViewById(R.id.desimage);
ImageLoader imageLoader = new ImageLoader(SubMenu.this);
imageLoader.DisplayImage(map.get(SubMenu.FLAG), image);
// crust.setOnItemSelectedListener(this);
// public void addListenerOnSpinnerItemSelection() {
final Button ok = (Button) dialogView.findViewById(R.id.ok);
ok.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
customDialog.dismiss();
}
});
final Button cncl = (Button) dialogView.findViewById(R.id.canc);
cncl.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
customDialog.dismiss();
}
});
