I am developing an android App.
I places LinearLayout on ListView. I would like to scroll LinearLayout united with ListView.
My xml is below.
Could you tell me how to implement above?
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/header1"
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_margin="3dp"
android:choiceMode="singleChoice"
android:orientation="vertical" >
・・・
</LinearLayout>
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:choiceMode="singleChoice" />
</LinearLayout>
You should not put a ListView inside a ScrollView due to it being extremely expensive and defeats the purpose a ListView. Use a LinearLayout/RelativeLayout instead.
If you would like to populate the ListView items with a LinearLayout you will need to create an adapter that will get the data and populate the listView.
Here is some code that takes String values and displays them in the list.
public class MySimpleArrayAdapter extends ArrayAdapter<String> {
private final Context context;
private final String[] values;
public MySimpleArrayAdapter(Context context, String[] values) {
super(context, R.layout.rowlayout, values);
this.context = context;
this.values = values;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.rowlayout, parent, false);
TextView textView = (TextView) rowView.findViewById(R.id.label);
ImageView imageView = (ImageView) rowView.findViewById(R.id.icon);
textView.setText(values[position]);
// change the icon for Windows and iPhone
String s = values[position];
if (s.startsWith("iPhone")) {
imageView.setImageResource(R.drawable.no);
} else {
imageView.setImageResource(R.drawable.ok);
}
return rowView;
}
}
Where you inflate the rowlayout in the getView - This will be your LinearLayout.
http://www.vogella.com/tutorials/AndroidListView/article.html#androidlists_adapterintro - For more information.
Use ScrollView (example) :
<ScrollView 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"
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/header1"
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_margin="3dp"
android:choiceMode="singleChoice"
android:orientation="vertical" >
・・・
</LinearLayout>
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:choiceMode="singleChoice" />
</LinearLayout>
</RelativeLayout>
</ScrollView>
Remember that ScrollView can only have one child attribute, so you can f.e. use a Relative Layout to encapsulate LinearLayout and ListView
ListView has its own ScrollView, If you want to scroll LinearLayout then follow the this code.
Declare Scroll-view as parent and declare only one child Linearlayout inside it (Scrollview contain only one child)
Declare what ever you want inside the Linearlayout.
<ScrollView 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">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/header1"
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_margin="3dp"
android:choiceMode="singleChoice"
android:orientation="vertical" >
.
.
.
</LinearLayout>
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:choiceMode="singleChoice" />
</LinearLayout>
</ScrollView>

My activity_main.xml is evenly split vertically 3 ways with LinearLayout. I would like to fill the bottom LinearLayout with a ListFragment and populate it with data.
Currently, the ListFragment ignores the 3 LinearLayout and just places itself on top of them.
LstFragment.java
public class LstFragment extends ListFragment{
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
ViewGroup rootView = (ViewGroup) inflater.inflate(R.layout.fragmentlayout, container, false);
// Create an array of string to be data source of the ListFragment
String[] datasource={"English","French","Khmer","Japanese","Russian","Chinese"};
// Create ArrayAdapter object to wrap the data source
ArrayAdapter<String> adapter=new ArrayAdapter<String>(getActivity(),R.layout.rowlayout,R.id.txtitem,datasource);
// Bind adapter to the ListFragment
setListAdapter(adapter);
// Retain the ListFragment instance across Activity re-creation
setRetainInstance(true);
return rootView;
}
// Handle Item click event
public void onListItemClick(ListView l, View view, int position, long id){
ViewGroup viewg=(ViewGroup)view;
TextView tv=(TextView)viewg.findViewById(R.id.txtitem);
Toast.makeText(getActivity(), tv.getText().toString(),Toast.LENGTH_LONG).show();
}
}
MainActivity.java
public class MainActivity extends FragmentActivity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LstFragment lstfragment=(LstFragment)getSupportFragmentManager().findFragmentByTag("lstfragment");
if(lstfragment==null){
lstfragment=new LstFragment();
FragmentTransaction transact=getSupportFragmentManager().beginTransaction();
transact.add(android.R.id.content,lstfragment,"lstfragment");
transact.commit();
}
}
}
activity_main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

There are two more simple .xml layout files called fragmentlayout.xml which contains a simple ListView #id/android:list and a rowlayout.xml which has a single TextView #id/textitem.
Replace
android:layout_height="fill_parent"
with this line
android:layout_height="0dp"
inside all the three child linear layouts
Reason
android.R.id.content gives you the root element of a view, without having to know its actual name/type/ID. That's why your Fragment is appearing at the top of everything.
You are trying to add your Fragment to wrong container here
transact.add(android.R.id.content,lstfragment,"lstfragment");
Solution
Add this
<FrameLayout
android:layout_width="fill_parent"
android:id="#+id/fragment_container"
android:layout_height="fill_parent">
</FrameLayout>
after 3rd LinearLayout but before closing the root LinerarLayout
then change to
transact.add(R.id.fragment_container,lstfragment,"lstfragment");
Also,
in all of the LinearLayout use this android:layout_height="wrap_content"
Hi i'm trying to put a listview inside a listview inside a listview.
The only problem is only the first listview is showing all elements correctly.
Every listview after that only contains one element.
UPDATE:
Creating my own non-scrollable listview fixed the problem.

Here is some code:

and so on...
What i'm trying to do now is setting an ArrayAdapter for all listviews:
AnlagenDetailsActivity:
...
long anlagenId = getIntent().getLongExtra("anlagen_id", 0);
Log.d(logger, "Details for Anlage: " + anlagenId);
LocalAnlagenAccessor accessor = new LocalAnlagenAccessor(this);
Anlage anlage = accessor.readAnlage(anlagenId);
TextView anlagenName = (TextView) findViewById(R.id.anlagenName_textview);
anlagenName.setText(anlage.getName());
ListView listView = (ListView) findViewById(R.id.listChecklisten);
AnlagenChecklistenAdapter adapter = new AnlagenChecklistenAdapter(this);
listView.setAdapter(adapter);
adapter.addAll(anlage.getChecklisten());
...
AnlagenChecklistenAdapter:
...
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View checklisteView = inflater.inflate(R.layout.anlagen_checklisten_listview, parent, false);
TextView checklisteName = (TextView) checklisteView.findViewById(R.id.checkliste_name);
checklisteName.setText(getItem(position).getArt());
ListView listView = (ListView) checklisteView.findViewById(R.id.listChecklistenPunkte);
AnlagenChecklistenPunktAdapter adapter = new AnlagenChecklistenPunktAdapter(checklisteView.getContext());
listView.setAdapter(adapter);
adapter.addAll(getItem(position).getChecklistenPunkte());
return checklisteView;
}
...
The same goes on for one more listview.
What am I doing wrong here?

having a trouble here with the sliding tabs. So I have completed the tutorial but when i had a ListView to my Pager it only shows on the bottom of the screen.
Here is my XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="0px"
android:layout_weight="1"
android:background="#android:color/white"/>
</LinearLayout>
And my XML from ListView:
<?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="fill_parent"

public class TabIssues extends Fragment {
private ListView mainListView ;
private CustomListAdapter_Issues listAdapter;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
Bundle b = getArguments();
int user_id = b.getInt("user_id");
boolean all = b.getBoolean("all");
WSConnectionIssues runner = new WSConnectionIssues(user_id, all);
runner.execute();
while (runner.download == AsyncTask.Status.RUNNING)
{
try
{
Thread.sleep(1);
} catch (Exception ex)
{
ex.printStackTrace();
}
}
View view = inflater.inflate(R.layout.activity_issues, container, false);
// Find the ListView resource.
mainListView = (ListView) view.findViewById(R.id.issue_list);
registerForContextMenu(mainListView);
// Create ArrayAdapter using the planet list.
View convertView = inflater.inflate(R.layout.row_issues, null);
listAdapter = new CustomListAdapter_Issues(this, runner.listIssues, convertView);
// Set the ArrayAdapter as the ListView's adapter.
mainListView.setAdapter(listAdapter);
return view;
}
Im using the phone for debug...as you can see blank...then the first item of my listview and if you scroll the others are there!
Could you try the listview layout as:
<?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"
android:orientation="vertical" >
<ListView
android:id="#+id/issue_list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:divider="#color/list_divider"
android:dividerHeight="1dp"
android:listSelector="#drawable/list_row_selector"/>
</RelativeLayout>
I've a layout activity_main.xml which contains this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
</LinearLayout>
And I've a layout, new_bucket.xml which contains this code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/newEntry"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<LinearLayout
android:id="#+id/main"
android:layout_width="fill_parent"
android:layout_height="100dp"
android:background="#253514"
android:clickable="true"
android:onClick="toggleAmagar"
android:orientation="vertical" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="text1"
android:textColor="#ffffff" />
</LinearLayout>
<LinearLayout
android:id="#+id/child"
android:layout_width="fill_parent"
android:layout_height="150dp"
android:layout_below="#id/main"
android:background="#666666"
android:clickable="true"
android:onClick="toggleAmagar"
android:orientation="vertical">
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="text2" />
</LinearLayout>
</LinearLayout>
What I want to achieve, is to programatically add several "instances" of new_bucket.xml to the main layout in activity_main.xml. Those instances, should appear inside the LinearLayout of activity_main.xml.
I'm a bit stuck at the moment. I've tried to just add a TextView to activity_main.xml but I can't even handle that...
LinearLayout my_root = (LinearLayout) getLayoutInflater().inflate(R.layout.activity_main, null);
LinearLayout A = new LinearLayout(this);
A.setOrientation(LinearLayout.HORIZONTAL);
TextView tv = new TextView(this);
tv.setText("This text should appear somewhere");
A.addView(tv);
my_root.addView(A);
But that TextView is never shown.
Can you help me out?
You mean like this?
LinearLayout container = (LinearLayout)findViewById(R.id.container);
View child = getLayoutInflater().inflate(R.layout.new_bucket, container);
container.addView(child);
See documentation.
layout activity_main.xml
// i added an Id for LinearLayout
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
>
</LinearLayout>
This code will add your new_bucket to your main LinearLayout
LinearLayout my_root = (LinearLayout) findViewById(R.id.container, null);
LayoutInflater mInflater = (LayoutInflater) getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
View bucket= (View) mInflater.inflate(R.layout.new_bucket, null);
my_root.addView(bucket);
Hope this work for you.
LinearLayout container = (LinearLayout)findViewById(R.id.container);
View child = getLayoutInflater().inflate(R.layout.new_bucket, container, false);
child.setId(0);
container.addView(child);
if u want to inflate multiple layout use for loop for this.
After so many help from so nice guys, I managed to do that.
I have not changed any Layout from the main question.
BUT java code is like this now:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LinearLayout my_root = (LinearLayout) findViewById(R.id.container);
LayoutInflater mInflater = (LayoutInflater) getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
View bucket= (View) mInflater.inflate(R.layout.new_bucket, null);
my_root.addView(bucket);
}
