Problem with spinner in user list inside action group

Question

In my application, I have a group of operations in which I have a custom ListView with ImageView, TextView and spinner. The error occurs when I click on the counter. here is the code.

final ListView list = (ListView)findViewById(R.id.submenu_list); MyCustomAdapter adapter = new MyCustomAdapter(this, mylist, 0, null, null); list.setAdapter(adapter); list.setTextFilterEnabled(true); private class MyCustomAdapter extends SimpleAdapter { public MyCustomAdapter(Context context, List<? extends Map<String, ?>> data, int resource, String[] from, int[] to) { super(context, data, resource, from, to); } public View getView(final int position, View convertView, ViewGroup parent) { if (convertView == null) { convertView = getLayoutInflater().inflate(R.layout.submenu_items, null); } ((TextView) convertView.findViewById(R.id.food_name)) .setText(estimated[position]); ((TextView) convertView.findViewById(R.id.prize)) .setText("Price : "+price[position]); ((ImageView) convertView.findViewById(R.id.imageview)) .setImageResource(image[position]); Spinner spinner = (Spinner) convertView.findViewById(R.id.spinner); ArrayAdapter<CharSequence> sadapter = ArrayAdapter.createFromResource(getParent(), R.array.number, android.R.layout.simple_spinner_item); sadapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner.setAdapter(sadapter); return convertView; } 

}

In my other activity within the action group, I have a simple layout with a spinner. To create a spinner, I have my code as shown below:

  public class FoodDetailPage extends Activity { Spinner spinner; Button back_button,my_order,add_order; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); View viewToLoad = LayoutInflater.from(this.getParent()).inflate(R.layout.food_details, null); this.setContentView(viewToLoad); back_button = (Button) findViewById(R.id.back_button); add_order = (Button) findViewById(R.id.add_order); back_button.setOnClickListener(new OnClickListener() { public void onClick(View view) { Intent intent =new Intent(FoodDetailPage.this,SubMenu.class); startActivity(intent); } }); this.spinner =(Spinner) findViewById(R.id.spinner); ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.number, R.layout.spinnerlayout); adapter.setDropDownViewResource(R.layout.spinnerlayout); spinner.setAdapter(adapter); } 

The problem is placing the counter in the custom ListView with the Activity group, my application freezes.

Answer 1

Try passing this.getPrent() to MyCustomAdapter as follows:

 MyCustomAdapter adapter = new MyCustomAdapter(this.getPrent(), mylist, 0, null, null); 

and create the Context variable in MyCustomAdapter

 private class MyCustomAdapter extends SimpleAdapter { Context mContext; public MyCustomAdapter(Context context,List<? extends Map<String, ?>> data, int resource, String[] from, int[] to) { super(context, data, resource, from, to); mContext = context; } //getView implementation } 

and pass that mContext to ArrayAdapter inside getView()

 ArrayAdapter.createFromResource(mContext, R.array.number, android.R.layout.simple_spinner_item);
