I'm trying to add buttons to a ListView of items so that a User can add specials to their "Favorites" by clicking a button/checkbox. Before adding this functionality, the layout of the list looked fine.
Here is the "before" java code:
ArrayList<Special> specials = specialda.getAllSpecialsByDay(selectedDay);
ListView listView = (ListView) findViewById(R.id.listView);
ArrayAdapter<Special> adapter = new ArrayAdapter<Special>(this, android.R.layout.simple_list_item_1, specials);
listView.setAdapter(adapter);
Now, after changing the Java code to this:
ArrayList<Special> specials = specialda.getAllSpecialsByDay(selectedDay);
ListView listView = (ListView) findViewById(R.id.listView);
ArrayAdapter<Special> adapter = new ArrayAdapter<Special>(this, android.R.layout.simple_list_item_multiple_choice, specials);
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
listView.setAdapter(adapter);
I end up with this distorted view:
Here is the xml layout file:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="com.yourfullname.flashcards.laxspecials.DisplaySpecials"
tools:showIn="@layout/activity_display_specials">
<ListView
android:id="@+id/listView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
</LinearLayout>
Any tips on what I am doing wrong or need to change?
Thanks
EDIT: Here is up display_specials_button.xml file:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/listView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:gravity="center_vertical"
android:checkMark="?android:attr/listChoiceIndicatorMultiple"
android:paddingStart="?android:attr/listPreferredItemPaddingStart"
android:paddingEnd="?android:attr/listPreferredItemPaddingEnd"
android:paddingLeft="?android:attr/listPreferredItemPaddingLeft"
android:paddingRight="?android:attr/listPreferredItemPaddingRight"/>
</LinearLayout>
You can dublicate source of android.R.layout.simple_list_item_multiple_choice
performing necessary changes:
<CheckedTextView 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:minHeight="?android:attr/listPreferredItemHeightSmall"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:gravity="center_vertical"
android:checkMark="?android:attr/listChoiceIndicatorMultiple"
android:paddingStart="?android:attr/listPreferredItemPaddingStart"
android:paddingEnd="?android:attr/listPreferredItemPaddingEnd" />
The difference is, that now you provide android:minHeight
and android:layout_height
in different way.
