Texto para marquesina dinámicamente

¿Es posible agregar texto de la codificación java de una vista de lista a scroll de marquesina en Android. Si es así, por favor, hágamelo saber cómo?

Si es necesario, publicaré el código utilizado. Éste era el XML para el listview usado es como sigue

• Los atributos de estilo no funcionan en las etiquetas de combinación
• Android: incluye un xml en otro xml
• Agregar un salto de línea en una posición determinada, sólo si es necesario
• Cambiar programaticamente el color de la forma en la lista de capas
• Diseño XML de Android para todos los dispositivos (pequeño / normal / grande / XLarge, etc.)

<?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="wrap_content" android:orientation="vertical" > <LinearLayout android:id="@+id/linearLayout1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" > </LinearLayout> <ListView android:id="@+id/audiolist_listView" android:layout_width="fill_parent" android:layout_height="0dp" android:layout_gravity="bottom" android:layout_weight="1" android:background="@drawable/backgroundimg" android:divider="@drawable/gradient" android:dividerHeight="1dp" android:scrollbars="vertical" > </ListView> </LinearLayout> 

La clase java para listview es la siguiente

 public class Audiovediolist extends Activity implements OnItemClickListener { private ListView audioList; private Intent frmHome; private ArrayList<HashMap<String, String>> dataList; private HashMap<String, String> map; private HashMap<String, String> data; private int Screen_Id; private AdView adView; String name; String mSign[] = { "Aries-Mesam", "Taurus-Vrushabham", "Gemini-Midhunam", "Cancer-Karkatakam", "Leo-Simham", "Virgo-Kanya", "Libra-Tula", "Scorpio-Vruchikam", "Sagittarius-Dhanussu", "Capricorn-Makaram", "Aquarius-Kumbham", "Pisces-Meenam" }; Integer mImages[] = { R.drawable.meshamu, R.drawable.vrushabhamu, R.drawable.medhunam, R.drawable.karkatakam, R.drawable.simham, R.drawable.kanya, R.drawable.tula, R.drawable.vruchikam, R.drawable.dhanussu, R.drawable.makaramu, R.drawable.kumbhamu, R.drawable.meenamu }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_RIGHT_ICON); setContentView(R.layout.list); frmHome = getIntent(); getIntentValues(); initUI(); setUI(); uiListener(); } private void initUI() { audioList = (ListView) findViewById(R.id.audiolist_listView); dataList = new ArrayList<HashMap<String, String>>(); adView = new AdView(this, AdSize.SMART_BANNER, "a150b89c23af3b2"); LinearLayout layout = (LinearLayout) findViewById(R.id.linearLayout1); layout.setGravity(Gravity.TOP); layout.addView(adView); adView.loadAd(new AdRequest()); } private void uiListener() { audioList.setOnItemClickListener(this); } private void getIntentValues() { String id = frmHome.getStringExtra("Activity_Id"); Screen_Id = Integer.parseInt(id); if (Screen_Id == 1) { getWindow().setFeatureDrawableResource(Window.FEATURE_RIGHT_ICON, R.drawable.audioo); this.setTitle(getResources().getString(R.string.audio)); this.setTitleColor(getResources().getColor(R.color.Beige)); } else { this.setTitle(getResources().getString(R.string.video)); this.setTitleColor(getResources().getColor(R.color.Beige)); getWindow().setFeatureDrawableResource(Window.FEATURE_RIGHT_ICON, R.drawable.videoo); } } private void setAdapter() { SimpleAdapter adapter = new SimpleAdapter(this, dataList, R.layout.list_row, new String[] { "Image", "text" }, new int[] { R.id.audiolist_row_img, R.id.audiolist_row_tv }); audioList.setAdapter(adapter); } private void setUI() { for (int a = 0; a <= 11; a++) { map = new HashMap<String, String>(); map.put("Image", "" + mImages[a]); map.put("text", mSign[a]); dataList.add(map); map = null; } } @Override protected void onStart() { super.onStart(); setAdapter(); } @Override public void onBackPressed() { super.onBackPressed(); System.gc(); } @Override protected void onDestroy() { super.onDestroy(); adView.destroy(); } /* * private class NextTask extends AsyncTask<Void,Void,Void> { ProgressDialog * progressDailog = new ProgressDialog(Audiovediolist.this); * * @Override protected void onPreExecute() { super.onPreExecute(); * progressDailog.setTitle("Please Wait"); * progressDailog.setMessage("URL Data Loading ..."); * progressDailog.setProgressStyle(ProgressDialog.STYLE_SPINNER); * progressDailog.setCancelable(true); progressDailog.show(); } * * @SuppressWarnings("static-access") * * @Override protected Void doInBackground(Void... params) { return null; } * * @Override protected void onPostExecute(Void result) { * progressDailog.dismiss(); } } */ @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { data = dataList.get(position); //FinalConstants.AUDIO_VIDEO = "list"; try { NetWorkCheck netWork = new NetWorkCheck(); if (netWork.isNetWorkConnection(this)) { if (Screen_Id == 1) { // new NextTask().execute(); Intent audioInt=new Intent(getApplicationContext(),AudioView.class); audioInt.setType(data.get("text")); startActivity(audioInt); } else if (Screen_Id == 2) { Intent vedioInt = new Intent(this, VideoPlayActivity.class); vedioInt.setType(data.get("text")); startActivity(vedioInt); } } else { netWork.alert(); } } catch (Exception e) { e.printStackTrace(); Toast.makeText(this, "Problem while ListItemClick", Toast.LENGTH_SHORT).show(); } } }
