I want to display only 5 rows in a ListView and rest of them should be scrollable.So far i have tried this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<EditText
android:id="#+id/txtFilename"
android:layout_width="375dp"
android:layout_height="wrap_content"
android:layout_margin="10dp" />
<ListView
android:id="#+id/ListView01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:scrollbarSize="2dp"
android:
/>
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/gray"
android:padding="5dp" >
<Button
android:id="#+id/btnOk"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="OK"/>
<Button
android:id="#+id/btnCancel"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="CANCEL"/>
</LinearLayout>
</LinearLayout>
and in java code
public class MainActivity extends Activity {
private ListView list1;
private String array[] = { "Iphone", "Tutorials", "Gallery", "Android",
"item 1", "item 2", "item3", "item 4" };
#SuppressWarnings("unchecked")
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
//parentLayout.add(childLayout);
setContentView(R.layout.activity_main);
list1 = (ListView) findViewById(R.id.ListView01);
// By using setAdpater method in listview we an add string array in
// list.
list1.setAdapter(new ArrayAdapter(this,android.R.layout.simple_list_item_1, array));
}
have any idea how to achieve it

I have written Demo for this Like:
if you want to fix Height of ListView to 5 items. then you have to set Height of ListView pragmatically by calculating listItems height.
First you need to create Layout for List Item and give it some fixed height, here i'm added height in Tag cause runtime i was getting layouts height as 0.
This is ListItem Layout
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/relativeLayout"
android:layout_width="fill_parent"
android:background="#android:color/black"
android:tag="40"
android:layout_height="40dp" >
<TextView
android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="XXX"
android:textColor="#android:color/darker_gray"
android:textSize="30sp" />
<TextView
android:id="#+id/text2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_toRightOf="#+id/text"
android:text="ZZZ"
android:textColor="#android:color/darker_gray"
android:textSize="30sp" />
</RelativeLayout>
and to set Height of ListView:
list = (ListView) findViewById(R.id.listView1);
adapter = new Adapter(MainActivity.this, setter);
list.setAdapter(adapter);
RelativeLayout.LayoutParams lstViewParams = (LayoutParams) list.getLayoutParams();
View lisItemInflatedView = View.inflate(this, R.layout.item, null);
RelativeLayout relLayoutInLstItem = (RelativeLayout) lisItemInflatedView.findViewById(R.id.relativeLayout);
final float scale = this.getResources().getDisplayMetrics().density;
int pixels = (int) ( Integer.parseInt( relLayoutInLstItem.getTag().toString() ) * scale + 0.5f);
int listHeigt = pixels * 5 + 5;
lstViewParams.height = listHeigt;
here's the screenshot..
Hope this will Help.

Like it is said in the title I want to add 2 entries of two different EditText into 1 listrowitem of my ListView.
Now I just can add one entry.
onCreateView of my fragment
final ListView listView = (ListView) rootView.findViewById(R.id.listViewswipeview);
final EditText editText = (EditText) rootView.findViewById(R.id.editTextswipeView);
final EditText editText2 = (EditText) rootView.findViewById(R.id.editText2);
Button btnswipeview = (Button) rootView.findViewById(R.id.imagebuttonswipeview);
listItems = new ArrayList<String>();
listItems.add("First Item - added on Activity Create");
adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, listItems);
listView.setAdapter(adapter);
btnswipeview.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View View) {
Toast toast = Toast.makeText(getActivity(),
"You clicked the button",
Toast.LENGTH_SHORT);
toast.show();
listItems.add(editText.getText().toString());
adapter.notifyDataSetChanged();
}
});

So if I make a entry in each of the two EditText objects the first one should be added to android:id="#+id/mainText" and the second one to android:id="#+id/textView2" of the listrowitem.
How is it possible to do it?
Rather than using the stock ArrayAdapter with a built-in row layout:
adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, listItems);
you'll probably want to create your own Adapter that extends ArrayAdapter, and pass it your custom row layout R.layout.swipeviewrowitem. You can add logic inside the custom Adapter to handle inputs to the EditTexts.
I am work on ArrayList.I want to display ArrayList in ListView ,I don't have any idea about using ArrayList in ListView.
In the picture "Cumputer Science" is the subject ,it should come under sub and other values also come under each one.

Try to use TableLayout and then create rows dynamically according to your need.
public class MainActivity extends Activity {
public static final String[] Subject = new String[] { "Maths","Computer", "english"};
private ListView lv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lv=(ListView)findViewById(R.id.listView1);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, Subject);
lv.setAdapter(adapter);
}
}
PLease help me with layout of the two list views placed vertically in the Linear Layout. Problem is that if list1 had more data than list2 is not visible and it not scrollable, using scollview is not solution.

If I use the scrollview then it is wrapping up the listview for only first row.
Please suggest something.

EDIT : CODE FOR THE TWO LISTVIEWS:
{
arrayofWebData.add(cn);
listAdapter = new SelectArralAdapter(getActivity(),
arrayofWebData);
List_events.setAdapter(listAdapter);
}
For the Second ListView it is as follows :
if ((year == event_year) && (event_month == month))
{
arrayofWebDataPress.add(cn);
listAdapter_press = new SelectArralAdapter_Press(getActivity(),arrayofWebDataPress);
List_events_press.setAdapter(listAdapter_press);
i++;
}
Array Adapter for the two ListViews :
class SelectArralAdapter_Press extends ArrayAdapter<PressDB> {
private LayoutInflater inflater;
public SelectArralAdapter_Press(Context context,
ArrayList<PressDB> arrayofWebDataPress) {
super(context, R.layout.speech_list_item, R.id.event_title,
arrayofWebDataPress);
inflater = LayoutInflater.from(context);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder_Press holder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.speech_list_item, null);
holder = new ViewHolder_Press(convertView);
convertView.setTag(holder);
} else {
holder = (ViewHolder_Press) convertView.getTag();
}
holder.populateFrom(arrayofWebDataPress.get(position));
return (convertView);
}
}
class ViewHolder_Press{
public TextView event_name = null;
public TextView event_date = null;
public ViewHolder_Press(View row) {
event_name = (TextView) row.findViewById(R.id.event_title);
event_date = (TextView) row.findViewById(R.id.event_date_time);
}
void populateFrom(PressDB eventsMainDB) {
event_name.setText(eventsMainDB.press_name);
event_date.setText(eventsMainDB.press_date + " ");
}
}
For the second Adaper :
class SelectArralAdapter extends ArrayAdapter<SpeechDB> {
private LayoutInflater inflater;
public SelectArralAdapter(Context context,
ArrayList<SpeechDB> arrayofWebData) {
super(context, R.layout.speech_list_item, R.id.event_title,
arrayofWebData);
inflater = LayoutInflater.from(context);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.speech_list_item, null);
holder = new ViewHolder(convertView);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.populateFrom(arrayofWebData.get(position));
return (convertView);
}
}
class ViewHolder {
public TextView event_name = null;
public TextView event_date = null;
public ViewHolder(View row) {
event_name = (TextView) row.findViewById(R.id.event_title);
event_date = (TextView) row.findViewById(R.id.event_date_time);
}
void populateFrom(SpeechDB eventsMainDB) {
event_name.setText(eventsMainDB.speech_name);
event_date.setText(eventsMainDB.speech_date + " ");
}
}
Try this.
If you want to go with the xml design then you have to give the fix size, either by using the weight (this is most preferable) or by giving the fix size in dp.

i am getting this screen at design time.
i have used like:
<ScrollView

android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFF">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center">
// first linearlayout which is holding one textview and a listview

">
<TextView
/>
<ListView
android:id="#+id/failed_list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_marginTop="5dp"/>
</LinearLayout>
// second linearlayout which is holding one textview and a listview

// and finally i have added a button in the parent linearlayout

you can try this.
Try out as below :
Here is the solution to more than one ListView within the same layout file. You can set the layout files as the below layout by providing the equal weights to each layout inside the LinearLayout.
<LinearLayout android:layout_weight="1"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
<ListView android:id="#+id/list1"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
</ListView>
</LinearLayout>
<LinearLayout android:layout_weight="1"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
<ListView android:id="#+id/list2"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
</ListView>
</LinearLayout>
Java Code

For more details you can refer the Link which have given the solution for same.
I hope it will help you.
Thanks.
You can take something like this.
<LinearLayout>
<ScrollView>
<LinearLayout>
{Your All code of controls}
</LinearLayout>
</ScrollView>
</LinearLayout>
OR uo can take <ScrollView> as parent tag..
You can do something like this. as per my Knowledge...
I solved the issue by using section headers and combining the two listviews into one listview and categorizing them by help of Section headers.
my app needs to display data in a list, I walked through some tutorials and figured out to use a header.xml and row.xml. It works fine but now I would like to add more stuff on my header.xml and I found out that the entire header.xml is scrolling with the row.xml as well, which I dont really want.
Any solution that doesn't require me to rewrite and change my code style completely?

Don't use ListActivity. I think it is a bad practice. Use a regular Activity. Just insert a ListView with an id "#android:id/list" into header.xml.
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
android:orientation="horizontal"
android:paddingBottom="6dip"
android:paddingTop="4dip" >

android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Date"
android:textColor="#FFFFFF"
android:textSize="16dp" />
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="name"
android:textColor="#FFFFFF"
android:textSize="16dp" />
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Time"
android:textColor="#FFFFFF"
android:textSize="16dp" />
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Rating"
android:textColor="#FFFFFF"
android:textSize="16dp" />
</LinearLayout>
<ListView
android:id="#android:id/list"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
</ListView>
And you can get the list reference by doing:
ListView lv = (ListView)findViewById(R.id.list);
Setting the Header of a ListView means that it will be the first item of your list, but still will scroll with the list itself.
In your case, you can create some kind of layout (similar to header.xml) and place it above the ListView.
Instead of ListActivity, extend from Activity
Create a main_layout.xml that define some views and a ListView.
main_layout
<include header.xml/>
<listview>
If you don't want your header and footer views to scroll with your ListView, then make sure that you use the addHeaderView() and addFooterView() BEFORE you call your setAdapter() method. I would recommend moving the setAdapter() method to your onCreate() method.
This is my main.xml:`
<RelativeLayout

android:orientation="vertical"
android:layout_width="match_parent"
android:addStatesFromChildren="false"
android:layout_height="wrap_content">

android:layout_width="30dip" />

After I press one of the buttons its text alignment goes to the left, how can I make it stay in center?
something similar happens with the first table (header) (textview1, textview2) but here it also reduses the textsize the amount of the text in the view...
EDIT: I managed to find the code that causes the change but I don't know how to fix this.
Maybe some one can explain me why does this happen and how to fix it?
private void fillTableView(List<BatteryInfo> list) {
TextView leftHeader = (TextView) findViewById(R.id.leftHeader);
TextView rightHeader = (TextView) findViewById(R.id.rightHeader);
LayoutParams leftHeaderLayoutParams = leftHeader.getLayoutParams();
LayoutParams rightHeaderLayoutParams = rightHeader.getLayoutParams();
TableLayout contentTable = (TableLayout) findViewById(R.id.maintable);
contentTable.removeAllViews();
for (int i = list.size() - 1; i >= 0; i--) {
TextView tv1 = new TextView(this);
tv1.setTextColor(Color.BLACK);
tv1.setGravity(Gravity.CENTER);
tv1.setBackgroundColor(Color.LTGRAY);
tv1.setLayoutParams(leftHeaderLayoutParams);
tv1.setText(String.valueOf(list.get(i).getLevel()));
TextView tv2 = new TextView(this);
tv2.setTextColor(Color.BLACK);
tv2.setGravity(Gravity.CENTER);
tv2.setBackgroundColor(Color.WHITE);
tv2.setLayoutParams(rightHeaderLayoutParams);
tv2.setText(list.get(i).getDurationTimeInString());
TableRow tblRow = new TableRow(this);
tblRow.addView(tv1);
tblRow.addView(tv2);
contentTable.addView(tblRow);
}
}
After I use removeAllViews or any addView function the layout of the top most table changes as I explained before. Why does this happen?
You can fix this by changing the android:layout_width="30dip" and android:layout_width="70dip" in leftHeader and rightHeader to android:layout_width="fill_parent". I have to admit that I'm not entirely certain why that is, though.
Instead of clearing and re-filling a TableLayout every time, though, you might want to consider using a ListAdapter. It's much more suited to what you're doing (and will probably perform better, too).
UPDATE NUMBER 2:
Notice the change in the main.xml and the change in the onCreate method. This will make your header static while letting your listview scroll, and changing from TableLayout to LinearLayout for your buttons will fix the alignment issue.
Here's how to do this with a custom adapter instead of TableLayout (which isn't really meant for dynamic data like this):
Change you main.xml to this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:addStatesFromChildren="false" android:layout_height="wrap_content">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:layout_alignParentTop="true" android:id="#+id/header">
<TextView android:id="#+id/leftHeader" android:textColor="#android:color/black"
android:layout_margin="1dp" android:gravity="center_horizontal"
android:layout_weight="1" android:background="#ffcccccc" android:text="textview1"
android:layout_width="fill_parent" android:layout_height="wrap_content"/>
<TextView android:id="#+id/rightHeader" android:textColor="#android:color/black"
android:gravity="center_horizontal" android:layout_weight="1"
android:layout_margin="1dp" android:background="#android:color/white"
android:text="textview2" android:layout_width="fill_parent" android:layout_height="wrap_content"/>
</LinearLayout>
<LinearLayout android:id="#+id/buttonTable" android:orientation="horizontal"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:background="#android:color/black"
android:layout_alignParentBottom="true" >
<Button android:id="#+id/button_ResetData"
android:layout_height="wrap_content" android:layout_width="fill_parent"
android:text="Reset Data" android:layout_gravity="center"
android:layout_weight="1" />
<Button android:id="#+id/button_Refresh"
android:layout_height="wrap_content" android:layout_width="fill_parent"
android:text="Refresh" android:gravity="center"
android:layout_weight="1" />
</LinearLayout>
<ListView android:id="#+id/listView" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:layout_weight="1"
android:fadingEdge="none"
android:layout_below="#id/header" android:layout_above="#id/buttonTable">
</ListView>
Add XML layout files for your rows (row.xml):
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="wrap_content">
<TextView android:id="#+id/maintableLeft"
android:layout_height="wrap_content" android:layout_weight="1"
android:layout_marginRight="1dp" android:layout_marginLeft="1dp"
android:gravity="center_horizontal" android:background="#ffcccccc"
android:textColor="#android:color/black" android:layout_width="fill_parent" />
<TextView android:id="#+id/maintableRight"
android:layout_height="wrap_content" android:background="#ffcccccc"
android:textColor="#android:color/black" android:layout_weight="1"
android:layout_marginLeft="1dp" android:layout_marginRight="1dp"
android:gravity="center_horizontal" android:layout_width="fill_parent" />
</LinearLayout>
Now everything is in place to create a custom class from BaseAdapter to display your information (and make your layout work better):
class CustomAdapter extends BaseAdapter {
private List<BatteryInfo> info;
private LayoutInflater inflater;
public CustomAdapter(Context context, List<BatteryInfo> x) {
this.info = x;
inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public int getCount() {
return info.size();
}
public Object getItem(int position) {
return info.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
View v;
v = inflater.inflate(R.layout.row, parent, false);
BatteryInfo b = (BatteryInfo) getItem(position);
((TextView) v.findViewById(R.id.maintableLeft)).setText(b
.getDurationTimeInString());
((TextView) v.findViewById(R.id.maintableRight)).setText(b
.getLevel());
return v;
}
}
Modify your onCreate method to inflate the header, add it, and then bind your data to your ListView using the new CustomAdapter (I've created a fake BatteryInfo class for this example, you'll need to modify things slightly to get this working):
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final ListView lv = (ListView) this.findViewById(R.id.listView);
final Context context = this;
Button refresh = (Button) this.findViewById(R.id.button_Refresh);
refresh.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
List<BatteryInfo> x = new ArrayList<BatteryInfo>();
x.add(new BatteryInfo());
x.add(new BatteryInfo());
x.add(new BatteryInfo());
x.add(new BatteryInfo());
lv.setAdapter(new CustomAdapter(context, x));
}
});
}
