    copied!<p>I am struggling with showing results in a listview. So here is my application in short: </p> <p>First screen -> Different activities to perform and search is one of them. Once User chooses Search, next screen has an input box and two buttons. Based on input keyword, I search for results and want to show results on the next screen, but my next screen appears ,but the results don't appear. Here is some code from my app</p> <pre><code>public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.searchcriteria); txtSearch = (EditText)findViewById(R.id.searchstring); btnCurrentLoc = (Button)findViewById(R.id.currentlocation); btnCurrentLoc.setOnClickListener(new Button.OnClickListener(){ public void onClick(View view){ setContentView(R.layout.searchresults); String keyword = txtSearch.getText().toString(); performSearch(keyword); } }); } private void performSearch(String searchterm){ progressDialog = ProgressDialog.show(Search.this, "Please wait......", "Retrieving data ....",true,true); PerformSearchTask task = new PerformSearchTask(); task.execute(searchterm); progressDialog.setOnCancelListener(new CancelTaskOnCancelListener(task)); } private class PerformSearchTask extends AsyncTask&lt;String, Void, List&lt;Event&gt;&gt;{ @Override protected List&lt;Event&gt; doInBackground(String... arg0) { String query = arg0[0]; return eventGetter.find(query); } protected void onPostExecute(final List&lt;Event&gt; result){ runOnUiThread(new Runnable(){ public void run() { if(progressDialog != null){ progressDialog.dismiss(); progressDialog = null; } if(result != null){ Vector&lt;String&gt; ve = new Vector&lt;String&gt;(); for(Event event: result){ ve.add(event.title + "\n" + event.eventlocation + "\t" + event.eventdate); } String[] eventArray = new String[ve.size()]; for(int i = 0; i &lt; ve.size(); i++){ eventArray[i] = ve.get(i); } ListView lv = (ListView)findViewById(R.id.list); lv.setAdapter(new ArrayAdapter&lt;String&gt;(Search.this,R.layout.searchresults,eventArray)); } } }); } } </code></pre> <p>Searchresults' screen layout is as below</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;ScrollView android:id="@+id/resultsofsearch" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android" &gt; &lt;RelativeLayout android:id="@+id/relativelayout_1" android:layout_width="320px" android:layout_height="332px" xmlns:android="http://schemas.android.com/apk/res/android" &gt; &lt;Button android:id="@+id/back" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Back" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" &gt; &lt;/Button&gt; &lt;Button android:id="@+id/info" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Info" android:layout_alignParentTop="true" android:layout_alignParentRight="true" &gt; &lt;/Button&gt; &lt;ListView android:id="@+id/list" android:layout_width="wrap_content" android:layout_height="0dip" android:layout_weight="1.0" android:layout_below="@+id/back" android:layout_centerHorizontal="true" &gt; &lt;/ListView&gt; &lt;/RelativeLayout&gt; &lt;/ScrollView&gt; </code></pre>
