    <p>I came across a nice filterable listview tutorial and I was wondering how to determine what listview item is selected and display a toast. Here is the code:</p> <pre><code>package com.example.listview; import java.util.ArrayList; import java.util.List; import android.app.Activity; import android.content.Context; import android.os.Bundle; import android.text.Editable; import android.text.TextWatcher; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.view.ViewStub; import android.widget.BaseAdapter; import android.widget.EditText; import android.widget.FrameLayout; import android.widget.ListView; import android.widget.TextView; public class TestFilterListView extends Activity { FrameLayout historyContainer; ViewStub viewStub; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.history_container); historyContainer = (FrameLayout) findViewById(R.id.historyContainerLayout); EditText filterEditText = (EditText) findViewById(R.id.filter_text); filterEditText.addTextChangedListener(new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int count) { historyContainer.removeAllViews(); final List&lt;String&gt; tempHistoryList = new ArrayList&lt;String&gt;(); tempHistoryList.addAll(historyList); for(String data : historyList) { if(data.indexOf((s.toString())) == -1) { tempHistoryList.remove(data); } } viewStub = new ViewStub(TestFilterListView.this, R.layout.history_schedule); viewStub.setOnInflateListener(new ViewStub.OnInflateListener() { public void onInflate(ViewStub stub, View inflated) { setUIElements(inflated, tempHistoryList); } }); historyContainer.addView(viewStub); viewStub.inflate(); } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { // TODO Auto-generated method stub } @Override public void afterTextChanged(Editable s) { // TODO Auto-generated method stub } }); setViewStub(); } /********************************************************************************************************/ private void setViewStub() { historyList.add("first"); historyList.add("second"); historyList.add("third"); historyList.add("fourth"); historyList.add("fifth"); historyList.add("sixth"); historyList.add("seventh"); viewStub = new ViewStub(TestFilterListView.this, R.layout.history_schedule); viewStub.setOnInflateListener(new ViewStub.OnInflateListener() { public void onInflate(ViewStub stub, View inflated) { setUIElements(inflated, historyList); } }); historyContainer.addView(viewStub); viewStub.inflate(); } /********************************************************************************************************/ final List&lt;String&gt; historyList = new ArrayList&lt;String&gt;(); String displayName = ""; ListView historyListView; private void setUIElements(View v, List&lt;String&gt; historyLists) { if (v != null) { historyScheduleData.clear(); //historyList.clear(); historyScheduleData.addAll(historyLists); historyListView = (ListView) findViewById(R.id.historylist); historyListView.setAdapter(new BeatListAdapter(this)); registerForContextMenu(historyListView); } } private static class BeatListAdapter extends BaseAdapter { private LayoutInflater mInflater; public BeatListAdapter(Context context) { mInflater = LayoutInflater.from(context); } public int getCount() { return historyScheduleData.size(); } public Object getItem(int position) { return position; } public long getItemId(int position) { return position; } public View getView(int position, View convertView, ViewGroup parent) { ViewHolder holder; if (convertView == null) { convertView = mInflater.inflate(R.layout.history_list_view, null); holder = new ViewHolder(); holder.historyData = (TextView) convertView .findViewById(R.id.historytext); convertView.setTag(holder); } else { holder = (ViewHolder) convertView.getTag(); } holder.historyData.setText(historyScheduleData.get(position)); return convertView; } static class ViewHolder { TextView historyData; } } private static final List&lt;String&gt; historyScheduleData = new ArrayList&lt;String&gt;(); </code></pre> <p>}</p> <p>I thought about using </p> <pre><code>protected void onListItemClick(ListView l, View v, int position, long id) { if(position == 0) { Intent intent = new Intent(getApplicationContext(), GODoc1Activity.class); startActivity(intent); </code></pre> <p>But when I try to implement it, it does not work. Am I missing something here? How do I go about doing this?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
