Question

Im using a SimpleCursorAdapter to fill the list inside an AlertDialog. The SimpleCursorAdapter uses the android.R.layout.simple_list_item_1 layout.

The dialog pops up. The list has correct amount of entries. But nothing is displayed. If I choose one entry, the selected entry ist highlighted and the text from my cursor is displayed.

The selection chooses the right entry.

Here is my code:

Intent dataIntent = new Intent();
dataIntent.setData(Ereignistypen.CONTENT_URI);
Cursor cursor = managedQuery(dataIntent.getData(), new String[] {
        Ereignistypen._ID, // 0
        Ereignistypen.NAME // 1
    }, null, null, Ereignistypen.ORDERBY);

SimpleCursorAdapter typAdapter = new SimpleCursorAdapter(this, android.R.layout.simple_list_item_1, cursor,
        new String[] { Ereignistypen.NAME }, new int[] { android.R.id.text1 });

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle(R.string.ereignistyp);
builder.setAdapter(typAdapter, this);
AlertDialog typPicker = builder.create();
typPicker.show();

What do I wrong?

I checked Android SimpleCursorAdapter results not displaying in AlertDialog. But it was little helpfull to me.

EDIT:
If I switch to android.R.layout.simple_spinner_item the list is displayed in an ugly style. But the entries are visible.

Answer 1

The text is there but is not visible because of style.

I made my own layout with slightly different styles.
This is the original simple_list_item_1 out of sdk sources.

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
   android:id="@android:id/text1"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:textAppearance="?android:attr/textAppearanceLarge"
   android:gravity="center_vertical"
   android:paddingLeft="6dip"
   android:minHeight="?android:attr/listPreferredItemHeight"
/>

I extended to following:

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
   android:id="@android:id/text1"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:textAppearance="?android:attr/textAppearanceLarge"
   android:textColor="?android:attr/textColorPrimaryInverseDisableOnly"
   android:gravity="center_vertical"
   android:paddingLeft="6dip"
   android:minHeight="?android:attr/listPreferredItemHeight"
/>

Setting the textcolor explicit solved the problem.
I’m not shure which layout is used if I set the items with AlertDialog.builder.setItem
