POAndroid custom ListView unable to click on items
text
Body
copied!<p>So I have a custom ListView object. The list items have two textviews stacked on top of each other, plus a horizontal progress bar that I want to remain hidden until I actually do something. To the far right is a checkbox that I only want to display when the user needs to download updates to their database(s). When I disable the checkbox by setting the visibility to Visibility.GONE, I am able to click on the list items. When the checkbox is visible, I am unable to click on anything in the list except the checkboxes. I've done some searching but haven't found anything relevant to my current situation. I found <a href="https://stackoverflow.com/questions/895341/custom-list-clicking-with-checkboxes-in-android">this question</a> but I'm using an overridden ArrayAdapter since I'm using ArrayLists to contain the list of databases internally. Do I just need to get the LinearLayout view and add an onClickListener like Tom did? I'm not sure.</p> <p>Here's the listview row layout XML:</p> <pre><code><?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight" android:padding="6dip"> <LinearLayout android:orientation="vertical" android:layout_width="0dip" android:layout_weight="1" android:layout_height="fill_parent"> <TextView android:id="@+id/UpdateNameText" android:layout_width="wrap_content" android:layout_height="0dip" android:layout_weight="1" android:textSize="18sp" android:gravity="center_vertical" /> <TextView android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1" android:id="@+id/UpdateStatusText" android:singleLine="true" android:ellipsize="marquee" /> <ProgressBar android:id="@+id/UpdateProgress" android:layout_width="fill_parent" android:layout_height="wrap_content" android:indeterminateOnly="false" android:progressDrawable="@android:drawable/progress_horizontal" android:indeterminateDrawable="@android:drawable/progress_indeterminate_horizontal" android:minHeight="10dip" android:maxHeight="10dip" /> </LinearLayout> <CheckBox android:text="" android:id="@+id/UpdateCheckBox" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout> </code></pre> <p>And here's the class that extends the ListActivity. Obviously it's still in development so forgive the things that are missing or might be left laying around:</p> <pre><code>public class UpdateActivity extends ListActivity { AccountManager lookupDb; boolean allSelected; UpdateListAdapter list; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); lookupDb = new AccountManager(this); lookupDb.loadUpdates(); setContentView(R.layout.update); allSelected = false; list = new UpdateListAdapter(this, R.layout.update_row, lookupDb.getUpdateItems()); setListAdapter(list); Button btnEnterRegCode = (Button)findViewById(R.id.btnUpdateRegister); btnEnterRegCode.setVisibility(View.GONE); Button btnSelectAll = (Button)findViewById(R.id.btnSelectAll); btnSelectAll.setOnClickListener(new Button.OnClickListener() { @Override public void onClick(View v) { allSelected = !allSelected; for(int i=0; i < lookupDb.getUpdateItems().size(); i++) { lookupDb.getUpdateItem(i).setSelected(!lookupDb.getUpdateItem(i).isSelected()); } list.notifyDataSetChanged(); // loop through each UpdateItem and set the selected attribute to the inverse } // end onClick }); // end setOnClickListener Button btnUpdate = (Button)findViewById(R.id.btnUpdate); btnUpdate.setOnClickListener(new Button.OnClickListener() { @Override public void onClick(View v) { } // end onClick }); // end setOnClickListener lookupDb.close(); } // end onCreate @Override protected void onDestroy() { super.onDestroy(); for (UpdateItem item : lookupDb.getUpdateItems()) { item.getDatabase().close(); } } @Override protected void onListItemClick(ListView l, View v, int position, long id) { super.onListItemClick(l, v, position, id); UpdateItem item = lookupDb.getUpdateItem(position); if (item != null) { item.setSelected(!item.isSelected()); list.notifyDataSetChanged(); } } private class UpdateListAdapter extends ArrayAdapter<UpdateItem> { private List<UpdateItem> items; public UpdateListAdapter(Context context, int textViewResourceId, List<UpdateItem> items) { super(context, textViewResourceId, items); this.items = items; } @Override public View getView(int position, View convertView, ViewGroup parent) { View row = null; if (convertView == null) { LayoutInflater li = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE); row = li.inflate(R.layout.update_row, null); } else { row = convertView; } UpdateItem item = items.get(position); if (item != null) { TextView upper = (TextView)row.findViewById(R.id.UpdateNameText); TextView lower = (TextView)row.findViewById(R.id.UpdateStatusText); CheckBox cb = (CheckBox)row.findViewById(R.id.UpdateCheckBox); upper.setText(item.getName()); lower.setText(item.getStatusText()); if (item.getStatusCode() == UpdateItem.UP_TO_DATE) { cb.setVisibility(View.GONE); } else { cb.setVisibility(View.VISIBLE); cb.setChecked(item.isSelected()); } ProgressBar pb = (ProgressBar)row.findViewById(R.id.UpdateProgress); pb.setVisibility(View.GONE); } return row; } } // end inner class UpdateListAdapter } </code></pre> <p>edit: I'm still having this problem. I'm cheating and adding onClick handlers to the textviews but it seems extremely stupid that my onListItemClick() function is not being called at all when I am not clicking on my checkbox.</p>
