How can i resolve this issue.? I know asyctask will help... How can i resolve this
use handler ,
handler = new Handler();
handler.post(new Runnable() {
#Override
public void run() {
alertDialog.show();
}
});
I think for best performance is to do this in another activity
anyway,if not, use AsyncTask class, example:
listView_prev.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, final View arg1, int arg2, long arg3) {
//listview click event handling
TextView id = (TextView) arg1.findViewById(R.id.textView17);
final int id_To_Search = Integer.valueOf(id.getText().toString());
new displaysImages().execute(id_To_Search);
}});
....
class displaysImages extends AsyncTask<Integer, Void, Void> {
ProgressDialog dialog;
Cursor item=null;
String FilePathStrings[];
#Override
protected void onPreExecute() {
super.onPreExecute();
/* show ProgressDialog before doing anything*/
dialog = ProgressDialog.show(getApplicationContext(), "Veuillez patienter", "Chargement des données....", true);
}
#Override
protected Void doInBackground(Integer... param) {
try {
item=mydb.singlecons(param[0]);
Cursor att=mydb.attrs(param[0]);
Cursor picloc=mydb.singleconspic(param[0]);
att.moveToFirst();
List<String> list = new ArrayList<>();
// Log.d("temp",att.getColumnName(1));
while (!att.isAfterLast())
{
int l=att.getColumnCount();
Log.d("length", String.valueOf(l));
for(int i=2;i<l;i++){
Log.d("for","for");
if(att.getString(i)!=null){
String b= att.getColumnName(i)+" "+att.getString(i);
list.add(b);
Log.d("att",b);
}
}
Log.d("while","while");
att.moveToNext();
}
att.close();
Log.d("list", String.valueOf(list));
picloc.moveToFirst();
FilePathStrings = new String[picloc.getCount()];
int i=0;
while (!picloc.isAfterLast()){
Log.d("picloc",picloc.getString(2));
FilePathStrings[i]=picloc.getString(2);
i++;
picloc.moveToNext();
}
item.moveToFirst();
} catch (Exception e) {
e.printStackTrace();
dialog.dismiss();
}
return null;
}

Your ListView has a listener for the click events on list elements.
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
// Do something when a list item is clicked
}
But if you want to pas something else back from the adapter to the Activity or the Fragment that contains that ListView and Adapter, you should create a simple interface and set it as listener to your adapter. After that, set click events on your rows from within the adapter, and notify the Activity or Fragment using your own interface.
For example you have the interface defined like this
public interface OnItemClickedCustomAdapter {
public void onClick(ItemPosition position);
}
and in your Adapter class you will have a private member
private OnItemClickedCustomAdapter mListener;
and a method used to set the listener
public void setOnItemClickedCustomAdapter(OnItemClickedCustomAdapter listener){
this.mListener = listener;
}
From your Activity or Fragment where your ListView is defined, and your adapter is set, you will be able to call setOnItemClickedCustomAdapter with this as parameter, and there you go. Your activity will now listen for your events. To trigger an event, just call mListener.onClick() from your custom adapter. You can pass back data you need back to the Activity or Fragment, and from there you have access to your Header or Footer directly, and you can change the text on them.
I'm having an issue with calling startActivity() on an Intent from within my custom onClick Listener. The code compiles fine, but when it gets to that point in the execution, I get a nullPointerException.

After following advice in the first response, my adapter now looks like:

}
String item = getItem(position);
TextView proverbDate = (TextView)row.findViewById(R.id.proverb_date);
TextView proverbText = (TextView)row.findViewById(R.id.proverb_content);
String[] data = item.split("----");
proverbDate.setText(data[0]);
proverbText.setText(data[1]);
ImageButton emailButton = (ImageButton)row.findViewById(R.id.emailButton);
ImageButton twitterButton = (ImageButton)row.findViewById(R.id.twitterButton);
ImageButton facebookButton = (ImageButton)row.findViewById(R.id.facebookButton);
emailButton.setOnClickListener(new ProverbOnClickListener(data[0], data[1], "email", context));
twitterButton.setOnClickListener(new ProverbOnClickListener(data[0], data[1], "twitter", context));
facebookButton.setOnClickListener(new ProverbOnClickListener(data[0], data[1], "facebook", context));
return row;
}
}
However I'm receiving a compilation error.
No enclosing instance type of MainActivity is accessible.
Try Few modifications
this.ma = new MainActivity(); //it is wrong
Don't instantiate Activity
try like this
Context context;
public ProverbAdapter(Context context, int layout, int resId, String[] items) {
super(context, layout, resId, items);
this.context=context;
}
use this variable context where ever you need context
I created singe choice AlertDialog with radio buttons using ArrayAdapter. It's possible to dissmiss that alert dialog when Ratio is selected? I have OnClick listener in ArrayAdapter class holder.name.setOnClickListener, but i have no idea how to to that.
AlertDialog code:
Builder builder = new Builder(serveris, useris, paswordas, BuildBuildingsViewActivity.this, USER_AGENT);
ArrayList<AvailableBuildings> availableBuildings = builder.checkForPossibleBuildings(pastatas.getBuildingLink());
ArrayAdapter<AvailableBuildings> adapter = new AvailableBuildingsAdapter(BuildBuildingsViewActivity.this, R.layout.choice_main, availableBuildings, host, curdid, pastatas.getBuildingLink());
new AlertDialog.Builder(BuildBuildingsViewActivity.this)
.setSingleChoiceItems(adapter, 0, null)
.setPositiveButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
dialog.dismiss();
}
})
.show();
ArrayAdapter code:
public class AvailableBuildingsAdapter extends ArrayAdapter<AvailableBuildings> {
public DBAdapterBuild db_build;
public AvailableBuildingsAdapter(Context context, int textViewResourceId,ArrayList<AvailableBuildings> availableBuildings, String host, String curdid, String aiksteles_link) {
super(context, textViewResourceId, availableBuildings);
this.context = context;
this.availableBuildings = new ArrayList<AvailableBuildings>();
this.availableBuildings.addAll(availableBuildings);
this.host = host;
this.curdid = curdid;
this.aiksteles_link = aiksteles_link;
db_build = new DBAdapterBuild(context, host);
}
private String host;
private Context context;
private String curdid;
private String aiksteles_link;
private ArrayList<AvailableBuildings> availableBuildings;
static class ViewHolder {
RadioButton name;
}
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
ViewHolder holder;
if (convertView == null) {
LayoutInflater vi = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = vi.inflate(R.layout.choice_row, null);
holder = new ViewHolder();
holder.name = (RadioButton) convertView.findViewById(R.id.building_name);
convertView.setTag( holder );
holder.name.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
db_build.open();
RadioButton name = (RadioButton) v;
AvailableBuildings building = (AvailableBuildings) name.getTag();
Log.e( "Available: ", ""+building.getAvailable_title()+building.getAvailable_code());
Log.e( "Available: ", ""+db_build.insertTitle(1, building.getAvailable_title(), aiksteles_link, curdid, 0, 1, building.getAvailable_type(), "3", building.getAvailable_code()));
db_build.close();
}
});
} else {
// view already defined, retrieve view holder
holder = (ViewHolder) convertView.getTag();
}
AvailableBuildings building = availableBuildings.get(position);
if ( building == null ) {
}
holder.name.setText(building.getAvailable_title());
holder.name.setTag(building);
return convertView;
}
}
I solve this problem passing to ArrayAdapter constructor Dialog object and next doing like this:
holder.name.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
db_build.open();
RadioButton name = (RadioButton) v;
AvailableBuildings building = (AvailableBuildings) name.getTag();
Log.e( "Available: ", ""+building.getAvailable_title()+building.getAvailable_code());
Log.e( "Available: ", ""+db_build.insertTitle(1, building.getAvailable_title(), aiksteles_link, curdid, 0, 1, building.getAvailable_type(), "3", building.getAvailable_code()));
db_build.close();
dia.dismiss();
}
});
