Adding a Button below a ListView in a ListActivity

I need a ListActivity with a ListView that has a Button below it. So you can scroll the ListView while the Button stays on the bottom. It looks fine in the layout but when i launch the app, there is no Button.
That is the XML of my ListActivity:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:descendantFocusability="blocksDescendants"
tools:context=".PalettenActivity" >
<ListView
android:id="#+id/listViewPaletten"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_above="#+id/buttonPalettenBetaetigen"
android:entries="#layout/paletten_item"
android:minHeight="?android:attr/listPreferredItemHeight" >
</ListView>
<Button
android:id="#+id/buttonPalettenBetaetigen"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:text="Bestätigen" />
</RelativeLayout>
Here's the code of the paletten_item:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/layoutPalettenItem"
android:focusable="false"
android:focusableInTouchMode="false"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="10dp"
tools:context=".ChecklistAdapter" >
<TextView
android:id="#+id/textViewPalettenBez"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:gravity="left|center_vertical"
android:text="Bezeichnung"
android:textSize="25sp" />
<Button
android:id="#+id/buttonPalettenPlus"
android:layout_width="65dp"
android:layout_height="match_parent"
android:layout_alignParentRight="true"
android:text="+"
android:textSize="20sp" />
<TextView
android:id="#+id/textViewPalettenAnzahl"
android:layout_width="50dp"
android:layout_height="match_parent"
android:layout_alignBaseline="#+id/buttonPalettenPlus"
android:layout_alignBottom="#+id/buttonPalettenPlus"
android:layout_toLeftOf="#+id/buttonPalettenPlus"
android:gravity="center"
android:text="0"
android:textSize="20sp" />
<Button
android:id="#+id/buttonPalettenMinus"
android:layout_width="65dp"
android:layout_height="match_parent"
android:layout_alignBaseline="#+id/textViewPalettenAnzahl"
android:layout_alignBottom="#+id/textViewPalettenAnzahl"
android:layout_toLeftOf="#+id/textViewPalettenAnzahl"
android:text="-"
android:textSize="20sp" />
</RelativeLayout>
This is how i add the onClickListener to the Button in the onCreate() method of the ListActivity:
LayoutInflater itemInflater (LayoutInflater)getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View convertView = itemInflater.inflate(R.layout.activity_paletten, null);
btnPalettenBestaetigen = (Button)convertView.findViewById(R.id.buttonPalettenBetaetigen);
btnPalettenBestaetigen.setText("Bestätigen");
btnPalettenBestaetigen.setVisibility(View.VISIBLE);
btnPalettenBestaetigen.setEnabled(true);
btnPalettenBestaetigen.setClickable(true);
btnPalettenBestaetigen.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
try {
// do stuff
} catch (Exception e) {
Log.e(TAG, e.getMessage());
e.printStackTrace();
}
}
});
Here is my layout with the button visible:
Layout of my ListActivity
Why isn`t the Button visible when i launch the app?
I am glad for any help!

SirGrey was right in the end.
That must be a problem with your code... But i can't see the issue, if the activity shows nothing, must be something with with the inflater... – SirGery
The Problem was the Inflater so i did the following changes to my code:
I deleted android:entries="#layout/paletten_item" from the XML of my MainActivity
The MainActivity now extends Activity and no more ListActivity
I setContentView() in my onCreate() method of my MainActivity
I get the ListView by doing listViewPaletten = (ListView)findViewById(R.id.listViewPaletten);
and I dont use the Infalter anymore.
Thanks a lot for your Help!

If you want to scroll your ListView meanwhile the button stays in same position, try to use FloatingActionButton, it must solve your issue
<ListView
android:id="#+id/listViewPaletten"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:entries="#layout/paletten_item"
android:minHeight="?android:attr/listPreferredItemHeight" >
</ListView>
<com.google.android.material.floatingactionbutton.FloatingActionButton
android:id="#+id/fActionButton"
android:layout_width="180dp"
android:layout_height="180dp"
tools:ignore="MissingConstraints,VectorDrawableCompat"/>

Then try this, swap the activity that makes reference, cause this is from my project
<RelativeLayout 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"
tools:context=".Activities.MainActivities.CartActivity">
<ListView
android:id="#+id/listViewPaletten"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:ignore="MissingConstraints"
tools:layout_editor_absoluteX="1dp"
tools:layout_editor_absoluteY="1dp"
android:layout_above="#+id/buttonPalettenBetaetigen">
</ListView>
<Button
android:id="#+id/buttonPalettenBetaetigen"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_centerHorizontal="true"
android:layout_gravity="center_horizontal"
android:layout_alignParentBottom="true"
android:text="Bestätigen" />

When I add new text in listview then it should go to bottom of the page to see new messsage

You can try this out. But i suggest you to use to recyclerview instead of listview for Chat module.
private void scrollToBottom() {
listView.post(new Runnable() {
#Override
public void run() {
listView.setSelection(adapter.getCount() - 1);
}
});
}

Increasing scrollview by adding buttons in a relativelayout (or linearlayout ) from bottom to top

Could really use some help with this one.
I'm trying to start with a single button at the bottom of my screen. When my counter++ button is clicked, a second button will be dynamically created above the button at the bottom of the screen. I was able to get this far, the problem is that the height of my scrollview doesn't increase when my buttons reach the top of the screen. Please see my example below.
Example
I'm assuming the scrollview only increases when items are added below the current view although if that's the case, is there no way I can create several buttons starting at the bottom going upwards?
Here my code.
XML:
<RelativeLayout 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="wrap_content"
android:layout_height="wrap_content"
tools:context="com.example.bbetzner.ttt.Map">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
>
<RelativeLayout
android:id="#+id/layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<Button
android:id="#+id/count"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="count++"
/>
<Button
android:id="#+id/floor0"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:text="0"
/>
</RelativeLayout>
</ScrollView>
</RelativeLayout>
Java:
public void addfloor(){
Button myButton = new Button(this);
myButton.setText(""+floor);
margincount += 100;
RelativeLayout ll = findViewById(R.id.layout);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.ABOVE, R.id.floor0);
lp.addRule(RelativeLayout.CENTER_HORIZONTAL);
lp.bottomMargin = margincount;
ll.addView(myButton, lp);
}
I've also tried doing this in a linear layout to see if the scrollview would increase but I couldn't figure out how to stack buttons from bottom to top in a linear layout. :S
Thanks in advance, yall are awesome!

#Texas use below code using that you are achieving what you want:
<RelativeLayout 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="wrap_content"
android:layout_height="wrap_content">
<LinearLayout
android:id="#+id/layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<Button
android:id="#+id/count"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="count++" />
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:scrollbars="vertical">
<LinearLayout
android:id="#+id/lladdViews"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:gravity="bottom"
android:orientation="vertical">
<Button
android:id="#+id/floor0"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
android:text="0" />
</LinearLayout>
</ScrollView>
</LinearLayout>
and here is Java File:
public class SampleActivity extends Activity {
LinearLayout lladdViews;
Button count;
int floor = 0;
private int margincount = 0;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.sample_activity);
lladdViews = (LinearLayout) findViewById(R.id.lladdViews);
count = (Button) findViewById(R.id.count);
count.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
addfloor();
}
});
}
public void addfloor() {
Button myButton = new Button(this);
myButton.setText("" + floor);
margincount += 10;
RelativeLayout ll = new RelativeLayout(this);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.ABOVE, R.id.floor0);
lp.addRule(RelativeLayout.CENTER_HORIZONTAL);
lp.bottomMargin = margincount;
ll.addView(myButton, lp);
lladdViews.addView(ll);
}
}

Android Listview is not scrolling still not working

Good day!
I have tried a lot of other posts on stackoverflow but it didn't work for me,
maybe its because I'm new to Android Development.
My problem is as follow:
XML Layout:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/item_detail_container"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:gravity="center_horizontal"
tools:context=".ItemDetailActivity"
tools:ignore="MergeRootFrame" >
<TextView
android:layout_width="match_parent"
android:layout_height="89dp"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="Medium Text"
android:id="#+id/txtDetails"
android:layout_gravity="center_horizontal|top"
android:padding="5dp" />
<ListView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="369dp"
android:layout_gravity="center_horizontal|bottom" />
</FrameLayout>
Preview in Android Studio:
inside the onCreateView:
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) { }
Binding the listview:
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final View rootView = inflater.inflate(R.layout.fragment_item_detail, container, false);
List<Events> list = Events.getEvents();
int max = list.size();
String[] Values = new String[max];
for (int i = 0; i < max; i++) {
Events e = list.get(i);
Values[i] = e.getNaam();
}
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(
rootView.getContext(),
android.R.layout.simple_list_item_1, Values);
listView.setAdapter(arrayAdapter);
return rootview;
}
Another point is i can't click a list item wich is strange !
Any ideas or tips?
what do i wrong?
Kind Regards,
Stefan

</LinearLayout>
You need to add a LinearLayout around the scrollview, that way the scrollview knows inside what it should scroll. If this doesn't work, replace the ListView with another LinearLayout and add your items to the LinearLayout. I'm not sure if a View is capable of scrolling at all. Try first option first, otherwise try the latter. I know the latter will work for sure since I used the exact same design myself in an app I'm developing.

As already mentioned in the comment, you have to add a ScrollView around your ListView, e.g.:
<ScrollView>
<ListView ....>
</ListView>
</ScrollView>

Android - Listview item setonitemclicklistener not working

Below is my code for listview, got a problem clicking it, it wont even show the toast when itemclick, that means the onitemclicklistener was not listening when i click
itemList = new ArrayList<PostList>();

Button add = new Button(this);
add.setBackgroundResource(R.drawable.add_button);
applianceList.addFooterView(add);
itemAdapter = new PostAdapterList(MainActivity.this, itemList);
applianceList.setAdapter(itemAdapter);
applianceList.setOnItemClickListener(new OnItemClickListener() {
#Override

long arg3) {

Set

android:focusableInTouchMode="false"
for your ImageView in your custom layout file which is inflated in your list adapter.
