When i try to expand my expandable listview its expanded.But it compress itself to determine width and height.I want to float items that under expandable list.How can i do that? Thanks in advance

The image in Imageview comes from the data base. ImageView is shrinking if it is null, if not it adds image, but when i scroll the listview, things get messed up.
I did a lot of hard work, but i did not get resolved it.

Try something like that:
if (this.list.get(position).getResim()!=null) {
Holder.resim.setVisibility(View.Visible);
Holder.resim.setImageBitmap(this.list.get(position).getResim2());
}
else {
Holder.resim.setVisibility(View.Gone);
Holder.resim.setImageresource(0);

Recycle view overlap items on scroll

Hello everyone i am facing a problem with recycle view.
im using a recycle view with swipe to change item position functionality where user can change the position of items by long press items.
all items comes dynamical with different types of views.
everything is working good but when im trying to scroll the view then items displaying in recycle view are overlap each other.
i search on google and got the solution that is override the method .
#Override
public int getItemViewType(int position) {
return position;
}
when im using this method in my adapter class then my swipe to change view functionality stop working.
can anyone explain my why it's happening..?
Here is whole adapter class

layout with listview and text below

I have a text below a listview and I need that if listview contains more items, to push the text down more. Because many items in my listview, causes the view to look bad. Look at the example to understand
Picture
My code is
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="Mañana"
android:id="#+id/manianaTitle" />
<ListView
android:layout_width="match_parent"
android:layout_height="200dp"
android:id="#+id/listaManiana"
android:layout_gravity="center_horizontal" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="Tarde"
android:id="#+id/tardeTitle" />
<ListView
android:layout_width="match_parent"
android:layout_height="200dp"
android:id="#+id/listaTarde"
android:layout_gravity="center_horizontal" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="Noche"
android:id="#+id/nocheTitle" />
<ListView
android:layout_width="match_parent"
android:layout_height="200dp"
android:id="#+id/listaNoche"
android:layout_gravity="center_horizontal" />
</LinearLayout>

It is better to use a ListView with section. In that case you can categorize each section in your ListView instead of using many ListViews and TextViews.
I found this example from this website and I did some modification in the code
Create your List Item View
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/photo"
android:layout_width="80dp"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_margin="32dp"
android:src="#drawable/female"
android:contentDescription="#string/app_name"/>
<TextView
android:id="#+id/photo_details"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/app_name"
android:layout_marginLeft="16dp"
android:layout_toRightOf="#+id/photo"
android:layout_alignTop="#+id/photo"/>
</RelativeLayout>
Create a layout for the header section
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical" >
<TextView
android:id="#+id/text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#FFF"
android:gravity="center_vertical"
android:padding="5dp"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="#FF000000" />
</LinearLayout>
Create an adapter for your List View
import java.util.ArrayList;
import java.util.TreeSet;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;
class CustomAdapter extends BaseAdapter {
private static final int TYPE_ITEM = 0;
private static final int TYPE_SEPARATOR = 1;
private ArrayList<EntityObject> mData = new ArrayList<String>();
private TreeSet<Integer> sectionHeader = new TreeSet<Integer>();
private LayoutInflater mInflater;
public CustomAdapter(Context context) {
mInflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public void addItem(final EntityObject item) {
mData.add(item);
notifyDataSetChanged();
}
public void addSectionHeaderItem(final String item) {
mData.add(item);
sectionHeader.add(mData.size() - 1);
notifyDataSetChanged();
}
#Override
public int getItemViewType(int position) {
return sectionHeader.contains(position) ? TYPE_SEPARATOR : TYPE_ITEM;
}
#Override
public int getViewTypeCount() {
return 2;
}
#Override
public int getCount() {
return mData.size();
}
#Override
public String getItem(int position) {
return mData.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
int rowType = getItemViewType(position);
if (convertView == null) {
holder = new ViewHolder();
switch (rowType) {
case TYPE_ITEM:
convertView = mInflater.inflate(R.layout.snippet_item1, null);
holder.textView = (TextView) convertView.findViewById(R.id.photo_details);
holder.photo = (ImageView)convertView.findViewById(R.id.photo)
break;
case TYPE_SEPARATOR:
convertView = mInflater.inflate(R.layout.snippet_item2, null);
holder.textView = (TextView) convertView.findViewById(R.id.textSeparator);
break;
}
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.textView.setText(mData.get(position).getText());
holder.setImageResource(mData.get(position).getImage());
return convertView;

}

Make LinearLayout with TextView and ExpendableListView scrollable using CWAC-Merge

My problem is, that I have an activity with one big TextView and one ExpandableListView underneath the TextView. Unfortunately the text of the TextView is too long, so I can't see the details when I expand the ExpandableListView.
So my question is, how can I use CWAC-Merge in my Code, to get one big scrollable Activity.
I would like to have, that everything in the activity_contact.xml from scrollView1 to the bottom is scrollable! I already copied the necessary libs (merge-1.0.1.jar and sacklist-1.0.0.jar) to my Project, but I don't know how to apply the MergeAdapter. I would really appreciate, if someone could tell me where and how I have to use the MergeAdapter!
This is my activity_contact.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<include layout="#layout/titlebar" />
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="wrap_content"
android:layout_height="0dip"
android:layout_marginTop="0dp"
android:layout_weight="1"
android:fillViewport="true" >
<TableLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<TableRow
android:id="#+id/tableRow1"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<TextView

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:paddingLeft="5dp"

This is my Contact.java class:
public class Contact extends Activity {
private SparseArray<Group> groups = new SparseArray<Group>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_contact);
ExpandableListView listView = (ExpandableListView) findViewById(R.id.listView);
createData();
ExpandableListAdapter adapter = new ExpandableListAdapter(this, groups,
false, null);
listView.setAdapter(adapter);
}
private void createData() {
Group group1 = new Group(getString(R.string.stringGroup));
group1.children.add(getString(R.string.stringGroup2));
groups.append(0, group1);
}
}
This is my ExpandableListAdapter.java
public class ExpandableListAdapter extends BaseExpandableListAdapter {
private final SparseArray<Group> groups;

private boolean setOnClickListener;
private Class<?> onClickClass;
public ExpandableListAdapter(Activity act, SparseArray<Group> groups,
boolean setOnClickListener, Class<?> onClickListenerClass) {
activity = act;
this.groups = groups;
inflater = act.getLayoutInflater();
this.setOnClickListener = setOnClickListener;
this.onClickClass = onClickListenerClass;

MergeAdapter is a ListAdapter, not an ExpandableListAdapter. You cannot use MergeAdapter to solve your problem. You are welcome to read through the source code to MergeAdapter and attempt to figure out if there is a way to create a MergeExpandableListAdapter or something like that.
Or, come up with a UI that does not have a long TextView after the ExpandableListView.
