For my listview, I want to be able to display multiple textviews within it, with each textview displaying the items of a specific array associated with it. Right now is what I have:
public class GreatestHits extends ListActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, Array1));
ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
String text = (String) ((TextView)view).getText();
}
});
}
static final String[] Array1 = new String[] {"Item1", "Item2"};
static final String[] Array2 = new String[] {"Item1", "Item2"};
static final String[] Array3 = new String[] {"Item1", "Item2"};
and the xml for R.layout.list_item:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp"
android:textSize="16sp"
android:id= "#+id/textView1"
>
</TextView>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp"
android:textSize="16sp"
android:id= "#+id/textView2"
>
</TextView>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp"
android:textSize="16sp"
android:id= "#+id/textView3"
>
</TextView>
How would I put array 2 and array 3 into the code so it can be displayed in the textviews of listview lv?
ArrayAdapter can only display data from one array in one textview. You will have to provide this functionality yourself by extending BaseAdapter yourself. I can't compile android code at the moment, so the following code is untested... but it should at least give you an indication of what you can do.
public class TripleArrayAdapter extends BaseAdapter {
private String[] array1, array2, array3;
private LayoutInflater inflater;
public TripleArrayAdapter(Context context, String[] a1, String[] a2, String[]a3) {
array1 = a1;
array2 = a2;
array3 = a3;
inflater =
(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return array1.length;
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View currentView = convertView;
if(currentView==null) {
currentView = inflater.inflate(R.layout.list_item, parent, false);
}
TextView tView = (TextView)currentView.findViewById(R.id.textView1);
tView.setText(array1[position]);
tView = (TextView)currentView.findViewById(R.id.textView2);
tView.setText(array2[position]);
tView = (TextView)currentView.findViewById(R.id.textView3);
tView.setText(array3[position]);
return currentView;
}
}
Then, to use this adapter as your ListActivity's adapter, you would just say
setListAdapter(new TripleArrayAdapter(this, Array1, Array2, Array3));

i want to combine two LinearLayout, both have different TextView arrangement in them, in a single ListView. so the final look should be like below:
and i run it with my code, but the app wouldn't start. below are my code.
Activity class:
public class MainActivity extends Activity {
// Create list of items
String[] publicModeItems = {
"AAAAA",
"BBBBB"
};
String[] publicModeParameters = {
"YES",
"NO"
};
String[] publicModeResetExe = {
"CCCCC",
"DDDDD"
};

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
populateListView();
}
private void populateListView() {
CustomList adapter1 = new CustomList(this, publicModeItems, publicModeParameters);
// Build adapter
ArrayAdapter<String> adapter2 = new ArrayAdapter<String>(
this, // context for the activity
R.layout.text_view_test, // layout to use (create)
publicModeResetExe); // items to display
// Configure the list view
ListView list = (ListView) findViewById(R.id.PublicModeListView);
list.setAdapter(adapter1);
list.setAdapter(adapter2);
}
private class CustomList extends ArrayAdapter<String> {
private final Activity context;

Problem : I just run my code just now, and only 'CCCCC' and 'DDDDD' is showing. so do you have any idea on this?
You should inherit your list adapter from BaseAdapter rather than ArrayAdapter.
Rewrite adapter's getView() method to inflate layout according position, like below.
public View getView(int position, View convertView, ViewGroup parent) {
...
View rootView = null;
if (position == 0 || position == 1) {
rootView = layoutinflater.inflate(R.layout.text_views_1, null, true);
} else {
rootView = layoutinflater.inflate(R.layout.text_views, null, true);
}
...
return rootView;
}
You set the list adapter twice
list.setAdapter(adapter1);
list.setAdapter(adapter2);
in this case the current adapter is the second, not them both.
Use ListView with SimpleAdapter or a custom adapter and that will solve all your problems, check out this for SimpleAdapter tutorial to learn a the basics and this tutorial to learn how you can make multiple views instead of just 1. This tutorial is about creating custom adapter
BTW, I have few comments on your code and xml layout
First, there is no need for 2 TextViews for your bracket, you can easily add them programmatically to the String[] or even to YES/NO TextView.
Second, You're not using a ViewHolder in your CustomList adapter and this is not a good practice as every time you scroll your list, it creates new view although it can use already existing one.
I already solve this problem. but it seems not so convenient to use this method.
public class PublicModeActivity extends Activity {
// Create list of items
String[] publicModeItems = {
"AAAAA",
"BBBBB"
};
String[] publicModeParameters = {
"YES",
"NO"
String[] publicModeResEx = {
"",
"",
"CCCCC",
"DDDDD"
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
populateListView();
}
private void populateListView() {
CustomList adapter = new CustomList(this, publicModeItems, publicModeParameters, publicModeResEx);
// Configure the list view
ListView list = (ListView) findViewById(R.id.PublicModeListView);
list.setAdapter(adapter);
}
private class CustomList extends BaseAdapter {
private final Activity context;
private final String[] publicModeItems;
private final String[] publicModeParameters;
private final String[] publicModeResEx;
public CustomList(Activity context,
String[] publicModeItems,
String[] publicModeParameters,
String[] publicModeResEx) {
super();
this.context = context;
this.publicModeItems = publicModeItems;
this.publicModeParameters = publicModeParameters;
this.publicModeResEx = publicModeResEx;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
LayoutInflater layoutinflater = context.getLayoutInflater();
View rowView = null;
Log.i("PublicModeActivity", "" + position);
if (position < 2) {
rowView = layoutinflater.inflate(R.layout.text_views_1, null, true);
TextView txtPublicModeItems = (TextView) rowView.findViewById(R.id.PublicModeItems);
TextView txtPublicModeParameters = (TextView) rowView.findViewById(R.id.PublicModeParameters);
txtPublicModeItems.setText(publicModeItems[position]);
txtPublicModeParameters.setText(publicModeParameters[position]);
} else {
rowView = layoutinflater.inflate(R.layout.text_view_test, null, true);
TextView txtPublicModeResEx = (TextView) rowView.findViewById(R.id.PublicModeResEx);
txtPublicModeResEx.setText(publicModeResEx[position]);
}
return rowView;
}
#Override
public int getCount() {
return 4;
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
}
}
I need to put that blank string "", to match the number of row with the upper layout (text_views_1) even-though those blank string are use in different layout. so it is not so convenient especially when you want to display so many data. If someone here have much simpler method than this. feel free to share with me/us. i'm eager to learn. thank you!
I have an activity that get data (arraylist) from a previous activity and put it in a listview through a custom adapter. In this custom adapter i declare a textview (to show the data) and add a numberpicker for each row.
I want the user to be able to select a number (with numberpicker) and when he has finished, to click on a button (fini) that display data with its numberpicker value in a textview.
My activity code (choozQr3.java):
public class ChoozQr3 extends Activity {
Button fini;
ListView lv;
TextView logQr;
Context context;
ChoozQr3Adapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.choozqr_step3);
fini = (Button) findViewById(R.id.fini);
lv = (ListView) findViewById(R.id.listView1);
logQr = (TextView) findViewById(R.id.textView2);
Bundle b = getIntent().getExtras();
String[] sTemp = b.getStringArray("arrangedItems");
ArrayList<String> resultArr = new ArrayList<String>(Arrays.asList(sTemp));
adapter = new ChoozQr3Adapter(this, R.layout.choozqr_step3_textview, resultArr);
lv.setAdapter(adapter);
lv.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
fini.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
//ArrayList<String> finalItems = new ArrayList<String>();
for (int i = 0; i < adapter.getCount(); i++) {
Toast.makeText(getApplicationContext(),i+". " +adapter.getItem(i).toString(),Toast.LENGTH_LONG).show();
//finalItems.add(adapter.getItem(i).toString());
}
}
}
);
}
}
Here is the code of my customadapter :
public class ChoozQr3Adapter extends ArrayAdapter<String>{
private final List<String> list;
public ChoozQr3Adapter(Context context, int resource, List<String> items) {
super(context, resource, items);
list = items;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi;
vi = LayoutInflater.from(getContext());
v = vi.inflate(R.layout.choozqr_step3_textview, parent, false);
//ContentValues cv = new ContentValues();
}
TextView tvNomDuQr=(TextView)v.findViewById(R.id.NomQr);
NumberPicker npNbJours=(NumberPicker)v.findViewById(R.id.numberPickerOccurence);
tvNomDuQr.setText(list.get(position));
npNbJours.setMaxValue(365);
npNbJours.setMinValue(1);
npNbJours.setValue(1);
npNbJours.setWrapSelectorWheel(true);
return v;
}
}
And the XML related to the adapter :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/RelativeLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:paddingBottom="6dip"
android:paddingTop="4dip" >
<TextView
android:id="#+id/NomQr"
android:layout_width="400dp"
android:layout_height="80dp"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:gravity="center_vertical"
android:paddingLeft="6dip"
android:textAppearance="?android:attr/textAppearanceLarge" />
<NumberPicker
android:id="#+id/numberPickerOccurence"
android:layout_width="wrap_content"
android:layout_height="80dp"
android:layout_alignTop="#+id/NomQr"
android:layout_marginLeft="20dp"
android:layout_toLeftOf="#+id/textView1"
android:orientation="horizontal" />
<TextView
android:id="#+id/textView1"
android:layout_width="80dp"
android:layout_height="80dp"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:gravity="center_vertical"
android:paddingLeft="6dip"
android:text="jours"
android:textAppearance="?android:attr/textAppearanceLarge" />
</RelativeLayout>
Until now, i managed to do it with setOnItemClickListener as described in this code (from activity choozQr3.java) :
lv.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView<?> arg0, View v,int position, long arg3){
// when user clicks on ListView Item , onItemClick is called
// with position and View of the item which is clicked
// we can use the position parameter to get index of clicked item
TextView tvNomDuQr=(TextView)v.findViewById(R.id.NomQr);
NumberPicker npNbJours=(NumberPicker)v.findViewById(R.id.numberPickerOccurence);
String NomDuQr=tvNomDuQr.getText().toString();
Integer NbJours=npNbJours.getValue();
// Show The result
Toast.makeText(getApplicationContext(),"répéter "+NbJours+" fois le questionnaire "+NomDuQr,Toast.LENGTH_LONG).show();
}
});
But i don't know how to modify my fini.setOnClickListener () to achieve same result...
Any help would be greatly appreciated...
Finally find the solution by myself.
public void onClick(View v) {
ArrayList<String> QrEtOccurence = new ArrayList<String>();
TextView tvNomDuQr;
NumberPicker npNbJours;
Integer j = 0;
for (int i = 0; i < lv.getCount(); i++) {
v = lv.getChildAt(i);
tvNomDuQr=(TextView)v.findViewById(R.id.NomQr);
npNbJours=(NumberPicker)v.findViewById(R.id.numberPickerOccurence);
String NomDuQr=tvNomDuQr.getText().toString();
Integer NbJours=npNbJours.getValue();
String output = "Présenter durant "+NbJours+" jours le questionnaire "+NomDuQr;
QrEtOccurence.add(output);}
String[] outputStrArr = new String[QrEtOccurence.size()];
for (int i = 0; i < QrEtOccurence.size(); i++) {
outputStrArr[i] = QrEtOccurence.get(i);}
}
I created a list view using ListActivity and Adapter, what I want to do is add button. the number of button is dynamic, in fact in the previous activity the user can set the number of button to add. so I can not use a layout. the code to creat my listView is given below
public class AppList extends ListActivity {
private String[] mStrings = (String[]) GridViewAppInfoAdapter.lApplication
.toArray(new String[GridViewAppInfoAdapter.lApplication.size()]);
public void setApplication() {
for (int i = 0; i < GridViewAppInfoAdapter.lApplication.size(); i++) {
mStrings[i] = GridViewAppInfoAdapter.lApplication.get(i).toString();
}
}
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.d("toto", "la valeur de app" + GridViewAppInfoAdapter.lApplication);
//setContentView(R.layout.listview);
// setApplication();
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_multiple_choice, mStrings);
setListAdapter(adapter);
ListView listView = getListView();
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
}
}
Make use of a Custom Adapter and there you can add as buttons in the layout easily. You can refer to this tutorial also.

when running this application on Emulator, if i click with mouse nothing happens. But when i select any item on the list using navigation buttons on the KeyBoard and click Enter, it works fine.
when running the app on a device. If i go on click any item of the list, like some 10-20 times it works sometimes.
Edit:
Actually everything worked fine when i was using predefined ArrayAdapter<String> and android.R.simple_list_item. But i want a custom adapter
why is it so?
Its because in my ListView item layout i added
android:clickable="true"
for both the TextViews. So when i click on the ListView item it indeed is a click on these TextView whose onClick is not implemented. Removing the clickable attribute from the TextViews solved my problem.
Thanks everyone
Try making the RelativeLayout clickable and focusable.

I'm trying to place a spinner inside a list view item in android. The problem is this seems to prevent the row from being highlighted during a press and the onItemClickListener is not getting called by the ListView. Basically I am trying to mimic the functionality in the Google Music app. Does anyone know how to do this? This is the code I have been trying (I know it may not be the best... just throwing together a quick sample which shows the problem):
Activity:
public class ListViewTestActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ListView listView = (ListView) findViewById(R.id.listView1);
DataHolder data = new DataHolder(this);
DataHolder data1 = new DataHolder(this);
DataHolder data2 = new DataHolder(this);
DataHolder data3 = new DataHolder(this);
DataHolder data4 = new DataHolder(this);
DataAdapter d = new DataAdapter(this, R.layout.rowview, new DataHolder[] { data, data1, data2, data3, data4 });
listView.setAdapter(d);
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
Log.e("ERROR", "look at me!");
}
});
}
}
public class DataHolder {
private int selected;
private ArrayAdapter<CharSequence> adapter;
public DataHolder(Context parent) {
adapter = ArrayAdapter.createFromResource(parent, R.array.choices, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
}
public ArrayAdapter<CharSequence> getAdapter() {
return adapter;
}
public String getText() {
return (String) adapter.getItem(selected);
}
public int getSelected() {
return selected;
}
public void setSelected(int selected) {
this.selected = selected;
}
}
This is the list adapter:
public class DataAdapter extends ArrayAdapter<DataHolder> {
private Activity myContext;
public DataAdapter(Activity context, int textViewResourceId, DataHolder[] objects) {
super(context, textViewResourceId, objects);
myContext = context;
}
// We keep this ViewHolder object to save time. It's quicker than findViewById() when repainting.
static class ViewHolder {
protected DataHolder data;
protected TextView text;
protected Spinner spin;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = null;
// Check to see if this row has already been painted once.
if (convertView == null) {
// If it hasn't, set up everything:
LayoutInflater inflator = myContext.getLayoutInflater();
view = inflator.inflate(R.layout.rowview, null);
// Make a new ViewHolder for this row, and modify its data and spinner:
final ViewHolder viewHolder = new ViewHolder();
viewHolder.text = (TextView) view.findViewById(R.id.text);
viewHolder.data = new DataHolder(myContext);
viewHolder.spin = (Spinner) view.findViewById(R.id.spin);
viewHolder.spin.setAdapter(viewHolder.data.getAdapter());
// Used to handle events when the user changes the Spinner selection:
viewHolder.spin.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
viewHolder.data.setSelected(arg2);
viewHolder.text.setText(viewHolder.data.getText());
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
Log.d("DBGINF", "asdf");
}
});
// Update the TextView to reflect what's in the Spinner
viewHolder.text.setText(viewHolder.data.getText());
view.setTag(viewHolder);
Log.d("DBGINF", viewHolder.text.getText() + "");
} else {
view = convertView;
}
// This is what gets called every time the ListView refreshes
ViewHolder holder = (ViewHolder) view.getTag();
holder.text.setText(getItem(position).getText());
holder.spin.setSelection(getItem(position).getSelected());
return view;
}
}
Main layout for activity
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical"
android:layout_width="fill_parent" android:layout_height="fill_parent">
<ListView android:id="#+id/listView1" android:layout_height="match_parent" android:layout_width="match_parent" />
</LinearLayout>
Layout for a row:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="wrap_content" android:weightSum="1" >
<TextView android:layout_width="wrap_content"
android:layout_height="match_parent" android:id="#+id/text"
android:layout_weight="0.5" android:textSize="25sp" />
<Spinner android:layout_width="0dp" android:layout_height="wrap_content"
android:id="#+id/spin" android:prompt="#string/choice_prompt"
android:layout_weight="0.5" />
</LinearLayout>
Thanks for any help!
I had the same problem with ImageButton, and what was needed was to do
mImageButton.setFocusable(false);
I can't garantee it's the same for Spinner, but my money is on it.
Best regards.
