    <p>I've done all of the research on the matter. I know that Google thinks it's pointless and that the developers, know that it's not. I also know that there is no known workaround, but I know that I am close to making one. The user DougW posted this code:</p> <pre><code>public class Utility { public static void setListViewHeightBasedOnChildren(ListView listView) { ListAdapter listAdapter = listView.getAdapter(); if (listAdapter == null) { // pre-condition return; } int totalHeight = 0; for (int i = 0; i &lt; listAdapter.getCount(); i++) { View listItem = listAdapter.getView(i, null, listView); listItem.measure(0, 0); totalHeight += listItem.getMeasuredHeight(); } ViewGroup.LayoutParams params = listView.getLayoutParams(); params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1)); listView.setLayoutParams(params); } } </code></pre> <p>Which almost gets the job done for me. But when I try it, I get a NullPointer exception at the listItem.measure(0, 0) line. The listItem itself is initialized, but the method throws the exception anyway. Please tell me how I can fix this.</p> <p>Here is my code:</p> <pre><code>public class ExpenseReportsActivity extends Activity { private ListView lvReports; private ExpenseReportListAdapter adapter; private Button btnSend; private Button btnCancel; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.expensereports); lvReports = (ListView)findViewById(R.id.lv_reports); lvReports.setBackgroundResource(R.drawable.shape_expense_report_list); ColorDrawable cd = new ColorDrawable(0xFFffffff); lvReports.setDivider(cd); lvReports.setDividerHeight(1); adapter = new ExpenseReportListAdapter(this); lvReports.setAdapter(adapter); int totalHeight = 0; for (int i = 0; i &lt; adapter.getCount(); i++) { View listItem = adapter.getView(i, null, lvReports); listItem.measure(0, 0); totalHeight += listItem.getMeasuredHeight(); } ViewGroup.LayoutParams params = lvReports.getLayoutParams(); params.height = totalHeight + (lvReports.getDividerHeight() * (adapter.getCount() - 1)); lvReports.setLayoutParams(params); } } </code></pre> <p>Another workaround I am working on is using my custom view's onWindowFocusChanged method. It tells the exacts height of the view. The problem is that the event isn't fired while I am still in my Activiy's onCreate method, nor in my Activity's onWindowFocusChanged method. I tried a custom event, but it never fired (it was placed inside my custom view's onWindowFocusChanged method and the listener was in my Activity's onWindowFocusChanged method).</p>

    1. COBoris, could you tell what are you actually trying to achieve? I'm asking because it looks like you are on a wrong way on a higher level.

    2. COMy client wants an expense report form which he fills and sends when ready. But in most cases the form will contain a lot of fields, which won't fit on the display height-wise. So I have been instructed to create the form, which consists of the list of fields plus a few buttons, and make it scroll (the entire form, not just the list).

    3. CODoes the suggested `ListView.addFooterView(View v)` solve your problem?

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).
