<p>I'm trying to implement a piece of code I found to store the state of a <code>CheckBox</code> that is in a <code>ListView</code> but it didn't worked. Does anyone have any idea why my code from my adapter isn't working?</p> <pre><code>package kevin.erica.box; import java.util.ArrayList; import kevin.erica.box.R; import android.R.color; import android.content.Context; import android.view.LayoutInflater; import android.view.View; import android.view.View.OnClickListener; import android.view.ViewGroup; import android.widget.ArrayAdapter; import android.widget.CheckBox; import android.widget.ImageView; import android.widget.TextView; public class MobileArrayAdapter extends ArrayAdapter<String> { private final Context context; private final String[] values; private ArrayList<Boolean> itemChecked = new ArrayList<Boolean>(); public MobileArrayAdapter(Context context, String[] values) { super(context, R.layout.list_adapter, values); this.context = context; this.values = values; for (int i = 0; i < this.getCount(); i++) { itemChecked.add(i, false); // initializes all items value with false } } @Override public View getView(final int position, View covertView, ViewGroup parent) { LayoutInflater inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); View rowView = inflater.inflate(R.layout.list_adapter, parent, false); CheckBox textView = (CheckBox) rowView.findViewById(R.id.checkBox1); textView.setTextColor(0xFFFFFFFF); textView.setText(values[position]); //Store state attempt final CheckBox cBox = (CheckBox) rowView.findViewById(R.id.checkBox1); // your // CheckBox cBox.setOnClickListener(new OnClickListener() { public void onClick(View v) { CheckBox cb = (CheckBox) v.findViewById(R.id.checkBox1); if (cb.isChecked()) { itemChecked.set(position, true); // do some operations here } else if (!cb.isChecked()) { itemChecked.set(position, false); // do some operations here } } }); cBox.setChecked(itemChecked.get(position)); // this will Check or Uncheck the // CheckBox in ListView // according to their original // position and CheckBox never // loss his State when you // Scroll the List Items. return rowView; } } </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
