I'm quite a beginner on Android studio and I'm trying to make an application. I have one question : I have a Custom ListView and I want to add items to this ListView when I click on a button (open a dialogbox with editText). But I don't succeed! For the moment I succeeded in adding items to a simple List view, but I want now to add items to my custom ListView :
This is my custom ListView (i was inspired by the Internet) :
public class CustomList extends ArrayAdapter<String> {
private final Activity context;
private String[] web;
private final Integer[] imageId;
public CustomList(Activity context,
String[] web, Integer[] imageId) {
super(context, R.layout.list_single, web);
this.context = context;
this.web = web;
this.imageId = imageId;
}
@Override
public View getView(int position, View view, ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View rowView= inflater.inflate(R.layout.list_single, null, true);
TextView txtTitle = (TextView) rowView.findViewById(R.id.txt);
ImageView imageView = (ImageView) rowView.findViewById(R.id.img);
txtTitle.setText(web[position]);
imageView.setImageResource(imageId[position]);
return rowView;
}
}
This is now my current code which works but just add Items to a "normal" ListView
public class MenuActivity extends Activity {
ListView listplayer=null;
ImageButton addButton = null;
/** Items entered by the user is stored in this ArrayList variable */
ArrayList<String> list = new ArrayList<String>();
/** Declaring an ArrayAdapter to set items to ListView */
ArrayAdapter<String> adapter;
@Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_menu);
listplayer=(ListView) findViewById(R.id.list);
adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, list);
addButton = (ImageButton) findViewById(R.id.buttonaddplayer);
addButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Create custom dialog object
final Dialog dialog = new Dialog(MenuActivity.this);
dialog.setTitle(getResources().getString(R.string.addperson));
// Include dialog.xml file
dialog.setContentView(R.layout.dialoglayout);
// Set dialog title
// dialog.setTitle("Custom Dialog");
// set values for custom dialog components - text, image and button
final EditText text = (EditText) dialog.findViewById(R.id.editTextdialog);
dialog.show();
ImageButton validButton = (ImageButton) dialog.findViewById(R.id.imageButtonvalid);
// if decline button is clicked, close the custom dialog
validButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
list.add(text.getText().toString());
text.setText("");
adapter.notifyDataSetChanged();
dialog.dismiss();
}
});
listplayer.setAdapter(adapter);
}
});
}
Thank you for helping me. In fact I want to do an application where you can add player, but with smth "beautiful" and not the normals List view of android studio
