Listview does not show items


I`m realy getting frustrated,

I am trying to show some items from a XML file which i parsed but i can`t get them to show in my listview. Can anyone please help me to get this done?

Please provide some examplecode if possible, so that i can follow, as i pretty new to this.

Thank you in advance.

My code:

@Override 
    protected void onPostExecute(String result) { 
        //publishProgress(false); 
        // create the grid item mapping
        ListView kp = (ListView)findViewById(R.id.kpn);

        String[] from = new String[] {"col_1", "col_2"};
        int[] to = new int[] { R.id.editText1, R.id.editText1 }; // 2 EditText fields

        List<HashMap<String, String>> fillMaps = new ArrayList<HashMap<String, String>>();
        HashMap<String, String> map = new HashMap<String, String>();

        Document doc = Jsoup.parse(kpn);
        Elements tdsFromSecondColumn = doc.select("table.personaltable td:eq(0)");
        Elements tdsFromSecondColumn1 = doc.select("table.personaltable td:eq(1)"); 

        // Fill the HashMaps
        for (Element tdFromSecondColumn : tdsFromSecondColumn) {
            map.put("col_1", tdFromSecondColumn.text()); 
            fillMaps.add(map);

            System.out.println(tdFromSecondColumn.text()); 

        } 
        for (Element tdFromSecondColumn1 : tdsFromSecondColumn1) {
            map.put("col_2", tdFromSecondColumn1.text());
            fillMaps.add(map);

            System.out.println(tdFromSecondColumn1.text());
        }

        SimpleAdapter adapter = new SimpleAdapter(AndroidLogin.this, fillMaps, R.layout.main, from, to); 
        kp.setAdapter(adapter);

My layout:

Solution

  • You can't include editText1 and editText2 in your main layout file. When using a listview, you specify the layout for each row in a seperate file. Like so

    list_view_row.xml

    <?xml version="1.0" encoding="utf-8"?>
      <LinearLayout android:orientation="horizontal"
        android:width="fillParent"
        android:height="fillParent"
      />
    
    <EditText>
     android:inputType="textMultiLine" 
     android:id="@+id/editText1" 
     android:layout_height="wrap_content" 
     android:text="edit1" 
     android:layout_width="110dp">
    </EditText> 
    
    <EditText>
     android:layout_height="wrap_content" 
     android:layout_width="110dp" 
     android:id="@+id/editText2" 
     android:text="edit2"
     android:inputType="textMultiLine"
     android:layout_marginLeft="50dp"
    </EditText>
    
    </LinearLayout>
    

    You then do:

        SimpleAdapter adapter = new SimpleAdapter(AndroidLogin.this, fillMaps, R.layout.list_view_row, from, to);
