    text
    copied!<p>I have an activity that shows customer information. All the controls are drawn dynamically as the design for the screen is controlled by a central SQL database. (IE screen position, editable and mandatory) so there is no XML for the design.</p> <p>Now so far everything I have done has worked very well until I came to try adding a ListView object to list the customers communication data. (IE a list of phone numbers, emails, fax numbers or website URLs)</p> <p>This List view is added correctly and the first row of data is displayed but I cannot seem to get the anymore rows to display.</p> <p>The items are added into a table row and these are then added onto a table layout. Could this be the problem? However when adding the ListView item this is first added to a RelativeLayout item so this should allow more than one line to be displayed?!</p> <p>Any Ideas why this could be occurring? I have checked the values of my array and I definitely have more than one item in it.</p> <p>The following is the Activities onCreate method:</p> <pre><code>@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); model = SharedModel.getInstance(); dbHelper = new DatabaseHelper(this); LinearLayout baseLayout = new LinearLayout(this); baseLayout.setOrientation(LinearLayout.VERTICAL); // add the customer name and number field. // NOTE: We will always require this widget regardless of dialog design fields tvCustomerNameNumber = new TextView(this); tvCustomerNameNumber.setTextSize(20); baseLayout.addView(tvCustomerNameNumber); // buttons RelativeLayout.LayoutParams alignBotton = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout.LayoutParams.FILL_PARENT); LinearLayout buttons = new LinearLayout(this); buttons.setOrientation(LinearLayout.HORIZONTAL); alignBotton.addRule(RelativeLayout.ALIGN_BOTTOM, baseLayout.getId()); // button edit Button edit = new Button(this); edit.setId(EDIT_BUTTON_ID); edit.setText(dbHelper.getActivityString(dbHelper.getWritableDatabase(), model.getUserLang().getLanguage().GetCodeId(), "buttonEdit", 1001000)); edit.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { setButtonsEnabled(false, true, true); setControlsEnabled(true); } }); buttons.addView(edit); // button save Button save = new Button(this); save.setId(SAVE_BUTTON_ID); save.setText(dbHelper.getActivityString(dbHelper.getWritableDatabase(), model.getUserLang().getLanguage().GetCodeId(), "buttonSave", 1001000)); save.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { try { saveCustomer(); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }); buttons.addView(save); // button cancel Button cancel = new Button(this); cancel.setId(CANCEL_BUTTON_ID); cancel.setText(dbHelper.getActivityString(dbHelper.getWritableDatabase(), model.getUserLang().getLanguage().GetCodeId(), "buttonCancel", 1001000)); cancel.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { try { cancelChanges(); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }); buttons.addView(cancel); // add the buttons baseLayout.addView(buttons); // build up the table of controls TableLayout tl = new TableLayout(this); // get the dialog design json array for customer information dialogFields = model.getDialogDesignFields(); // reset the field type indexes addedIndexes = new ArrayList&lt;Integer&gt;(); addedCodeIndexes = new ArrayList&lt;Integer&gt;(); addedDateIndexes = new ArrayList&lt;Integer&gt;(); addedTextIndexes = new ArrayList&lt;Integer&gt;(); addedListIndexes = new ArrayList&lt;Integer&gt;(); mandatoryIndexes = new ArrayList&lt;Integer&gt;(); // for each control in the array for(int i=0;i&lt;=model.getDialogDesignFields().length() - 1; i++) { try { // if the control is for the customer page if(dialogFields.getJSONObject(i).get("formname").equals("CustomerInformation")){ handleField(tl, dialogFields.getJSONObject(i)); } } catch (JSONException e) { e.printStackTrace(); } } // Scroll view. // NOTE: We will always need this widget to enable us to scroll the page // if too many items are added for the display size ScrollView sv = new ScrollView(this); sv.addView(tl); baseLayout.addView(sv); // set the content view this.setContentView(baseLayout); // make sure we are not in edit mode setButtonsEnabled(true, false, false); setControlsEnabled(false); setResult(0); } </code></pre> <p>And now the handleField method that decides what to do with the field im adding:</p> <pre><code>private void handleField(TableLayout tl, final JSONObject field) throws JSONException { // get field index int id = field.getInt("viewindex") + 1; final String name = field.getString("name"); // if the name = CustomerAddressID don't do anything if(name.equals("CustomerAddressID") != true) { // if the name is not equal to CustomerCommunicationID if(name.equals("CustomerCommunicationID") == false) { if(id &gt; 0) { // create and add controls // add the field index to the addedIndexes.add(id); // layout parameters RelativeLayout.LayoutParams alignRight = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT); // if the field is mandatory if(field.getInt("mandatory") == 1) { TextView mandatory = new TextView(this); mandatory.setText("*"); tl.addView(mandatory); mandatoryIndexes.add(id); } // field name description TextView fn = new TextView(this); fn.setId(id + 1000); fn.setText(dbHelper.getActivityString(dbHelper.getWritableDatabase(), model.getUserLang().getLanguage().GetCodeId(), name, 1000030)); tl.addView(fn); // create a table row TableRow tr = new TableRow(this); tr.setId(id + 10000); tl.addView(tr); // create a relative layout RelativeLayout rl = new RelativeLayout(this); rl.setId(id + 100000); rl.setTag(field); rl.setBackgroundResource(R.drawable.myborder); // if the control is not disabled if(field.getInt("disabled") == 0) { // so we are adding a listener // if the name is code we are adding to code indexes if(name.endsWith("CODE") == true | name.equals("PreferredVisitDay")) { addedCodeIndexes.add(id); } else if (name.endsWith("DATE") == true) { addedDateIndexes.add(id); } else { addedTextIndexes.add(id); } // add a listener rl.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { // show the code picker for customer group JSONObject field = (JSONObject) v.getTag(); try { prepareDialog(field); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }); // image view ImageView iv = new ImageView(this); iv.setId(id + 1000000); iv.setImageResource(R.drawable.edit16x16); iv.setVisibility(View.GONE); alignRight.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, iv.getId()); rl.addView(iv, alignRight); } tl.addView(rl); // fieldValue TextView fv = new TextView(this); fv.setId(id + 10000000); fv.setTextSize(18); rl.addView(fv); } } else { if(id &gt; 0) { addedIndexes.add(id); // field name description TextView fn = new TextView(this); fn.setId(id + 1000); fn.setText(dbHelper.getActivityString(dbHelper.getWritableDatabase(), model.getUserLang().getLanguage().GetCodeId(), name, 1000030)); tl.addView(fn); // create a table row TableRow tr = new TableRow(this); tr.setId(id + 10000); tl.addView(tr); // create a relative layout RelativeLayout rl = new RelativeLayout(this); rl.setId(id + 100000); rl.setTag(field); rl.setBackgroundResource(R.drawable.myborder); tl.addView(rl); // list view ListView lv = new ListView(this); lv.setId(id + 10000000); lv.setTag(field); lv.setOnItemClickListener(new AdapterView.OnItemClickListener() { public void onItemClick(AdapterView&lt;?&gt; arg0, View view, int position, long id) { try { communicationClicked(arg0, view, position, id, field); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }); rl.addView(lv); } } } } </code></pre> <p>The ListView Item is added in the second block of code with the following code:</p> <pre><code>// list view ListView lv = new ListView(this); lv.setId(id + 10000000); lv.setTag(field); lv.setOnItemClickListener(new AdapterView.OnItemClickListener() { public void onItemClick(AdapterView&lt;?&gt; arg0, View view, int position, long id) { try { communicationClicked(arg0, view, position, id, field); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }); rl.addView(lv); </code></pre> <p>Finally the List view is populated with the following code:</p> <pre><code>} else if (name.equals("CustomerCommunicationID")){ // set communications value ListView lv = (ListView)findViewById(index + 10000000); // create an array adapter with the customer type data array ArrayAdapter&lt;Communication&gt; communicationAdapter = new ArrayAdapter&lt;Communication&gt;(this, R.layout.communication_menu_item, currentCustomer.getCustomerCommunications()); // assign the my customers list control the array adapter lv.setAdapter(communicationAdapter); Log.i(TAG, "Communications Assigned"); } else { </code></pre> <p>I have done a test and added a Listview at the top of my application and set the listadapter to my array and all the lines are displayed.</p> <p>So looks like Its to do with the Table rows</p>

An individual column

Larger individual text columns get their own page to allow for proper reading.
