Hi folks, I am a complete newbie to android so I guess this group is just the right one for me to start with :-)
I have the following problem. I have written my own ArrayAdapter class which cutomizes a ListView. More precisely I would like to have a list which contains a horizontal LinearLayout with one TextView and a ImageView per row. I have tried to achieve this by using the attached code which I created by following this tutorial http://lbellonda.blogspot.com/2007/12/android-how-to-show-items-with.html I have a class that extends ListActivity and looks like this: public class DDboard extends ListActivity{ @Override public void onCreate(Bundle savedInstanceState) { try{ super.onCreate(savedInstanceState); setContentView(R.layout.dd_list); String[] string1 = new String[2]; string1[0] = "Description 1"; string1[1] = "green"; String[] string2 = new String[2]; string1[0] = ""Description 2"; string1[1] = "yellow"; String[] string3 = new String[2]; string1[0] = ""Description 3"; string1[1] = "red"; ArrayList dAL = new ArrayList(); dAL.add(string1); dAL.add(string2); dAL.add(string3); DArrayAdapter daa = new DArrayAdapter(this, dAL); setListAdapter(daa); }catch(Exception e){ e.printStackTrace(); } } } Within this class, as you can see, I do instantiate DArrayAdapter and sending the current context and my ArrayList. Depending on what is in [1] of the String array I would like to place different images in my ImageView. But have a look at that later. DArrayAdapter looks like this: public class DArrayAdapter extends ArrayAdapter{ public DArrayAdapter(Context context, List<String[]> dds) { super(context, R.layout.dd_row, dds); } @Override public View getView(int position, View convertView, ViewGroup parent){ String[] stringArray = (String[]) getItem(position); DDListRow ddlr = new DDListRow(super.getContext(), stringArray); return ddlr; } } And DDListRow, which extends LinearLayout looks like this: public class DemandDashboardListRow extends LinearLayout { //String Title=""; TextView mText; ImageView mView; public DDListRow(Context context, String[] dd) { super(context); this.setOrientation(HORIZONTAL); this.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); mText = new TextView(context); mText.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); addView(mText); setText(dd[0]); mView = new ImageView(context); mView.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); if (demand[1].equals("red")){ mView.setImageResource(R.drawable.android_red); } if (demand[1].equals("yellow")){ mView.setImageResource(R.drawable.android_yellow); } if (demand[1].equals("green")){ mView.setImageResource(R.drawable.android_green); } addView(mView); } public void setText(String text) { mText.setText(text); } } I hope this is at least not complete BS but if I run the programm I get a ClassCastException at the method call "setListAdapter(daa);" in the ListActivity class. And to be honest, I don't have a clue what I am doing wrong. The res/layout files are created as described in the well-known notepad tutorial but I would post them immediately if they are of any help for you guys to solve my issue. Any help is greatly appreciated!!!
