Listview scrollt nicht bis zum letzten Eintrag

Question

Hallo, ich habe Probleme beim Scrollen, bis das letzte Scrolling in der Mitte aufhört, hier ist mein Layoutcode.

<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" 
tools:context="fragment.Equivalent"> 
<ListView 
    android:id="@+id/listView" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:visibility="visible" 
    android:layout_alignParentTop="true" 
    android:layout_alignParentStart="true" 
    android:focusable="false"/> 

<TextView 
    android:id="@+id/txt404" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_centerInParent="true" 
    android:text="Message that will be shown if the listview is empty" 
    android:textSize="21dp" 
    android:textStyle="bold" 
    android:visibility="invisible" /> 
</RelativeLayout>

Lösung wurde das Layout zu einem Constraint-Layout ändern und die Größe der Listenansicht zu ändern

<android.support.constraint.ConstraintLayout 
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="fragment"> 

<ListView 
    android:id="@+id/listView" 
    android:layout_width="399dp" 
    android:layout_height="485dp" 
    android:layout_marginEnd="8dp" 
    android:layout_marginRight="0dp" 
    android:focusable="false" 
    android:visibility="visible" 
    app:layout_constraintHorizontal_bias="0.0" 
    app:layout_constraintLeft_toLeftOf="parent" 
    app:layout_constraintRight_toRightOf="parent" 
    app:layout_constraintTop_toTopOf="parent" 
    tools:layout_constraintLeft_creator="1" 
    tools:layout_constraintTop_creator="1" 
    app:layout_constraintBottom_toBottomOf="parent" 
    android:layout_marginBottom="8dp" 
    app:layout_constraintVertical_bias="0.0" /> 

<TextView 
    android:id="@+id/txt404" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="" 
    android:textSize="21dp" 
    android:textStyle="bold" 
    android:visibility="invisible" 
    tools:layout_constraintTop_creator="1" 
    tools:layout_constraintRight_creator="1" 
    tools:layout_constraintBottom_creator="1" 
    app:layout_constraintBottom_toBottomOf="parent" 
    app:layout_constraintRight_toRightOf="parent" 
    tools:layout_constraintLeft_creator="1" 
    app:layout_constraintLeft_toLeftOf="parent" 
    app:layout_constraintTop_toTopOf="parent" 
    app:layout_constraintHorizontal_bias="0.503" 
    app:layout_constraintVertical_bias="0.391" /> 

    </android.support.constraint.ConstraintLayout>

Versuchen mit einer Scroll-Ansicht:

<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" 
    tools:context="fragment.Equivalent"> 
    <ScrollView 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      android:layout_alignParentRight="true" 
      android:layout_alignParentEnd="true" 
      android:scrollbarStyle="insideOverlay" 
      style="@android:style/Widget.Holo.ScrollView"> 
    <TableLayout 
     android:id="@+id/table_layout_id" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent"> 
    </TableLayout> 
    </ScrollView> 
</RelativeLayout> 

in Java-Datei, dies zu tun:

TableLayout ll = (TableLayout) findViewById(R.id.table_layout_id); 
TableRow row = new TableRow(this);
  
TableRow.LayoutParams lp = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT);
  
row.setLayoutParams(lp); 

 
 butt = new Button(this);
 //You can add button too, FYI 
butt.setText("TEST");
 
 
  
TextView tv = (TextView) findViewById(R.id.txt404); 

tv.setText("Text view");
  
tv2 = new TextView(this);
 //your job: add list view here 
tv2.setText("Text View 2");
 
 
  
row.addView(butt); 

 row.addView(tv1);
  
row.addView(tv2);
 
  
ll.addView(row, i); // where i is the row number, increment on addition
