I realize there are a ton of questions regarding this issue, but the solution of setting every view in the row.xml to focusable="false" and focusableInTouchMode="false" do not work, nor does getting the ListView from the ListActivity and setting setItemsCanFocus(false).
Weirdly, when registered for a context menu, the long tap works. The regular tap though? Nope. I tried setting listeners like OnItemClickListener to no avail.
I read somewhere that I might be able to remedy this by overriding getView() in my Adapter? I'm not too sure how that works though. Note, I don't want to know what view the user has clicked; I just care about the list row being clicked to initiate the corresponding code in onListItemClick().
Maybe there's something in my row.xml that's all wrong? Or is it affected by the way I set my ListView's adapter (placed in onResume() instead of onCreate() to update information)?

The Onlistitemclick will never be called because there is a clickable view in your list item. Remove the checkbox and see if you are able to get the clicks.
There is an alternative to using using a checkbox directly in your item layout. Use android:choiceMode="multipleChoice" for listview if it suits your needs.
Take a look at this link in how to create a custom adapter:
http://android-er.blogspot.com/2010/06/using-convertview-in-getview-to-make.html
In the Override getView() method, you could just set the row.setOnClickListener() to do what you needed to do when that list item is clicked.
Ideally, you would use convertView to fill a ViewHolder class so that you aren't recreating list items when they have already been created, but that's a different question.
Edit
Here's a slimmed down custom implementation of extending a SimpleCursorAdapter:
public class CatchCursorAdapter extends SimpleCursorAdapter {
private final Context mContext;
private final Cursor mCursor;
private final int layout;
private final LayoutInflater inflater;
private final class ViewHolder {
public ImageView catchImage;
public ImageView catchStar;
public TextView catchSpecies;
}
public CatchCursorAdapter(Context context, int layout, Cursor cursor) {
super(context, layout, cursor, new String[] { }, new int[] { });
this.mContext = context;
this.mCursor = cursor;
this.inflater = LayoutInflater.from(context);
this.layout = layout;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder;
if (convertView == null) {
convertView = inflater.inflate(layout, parent, false);
viewHolder = new ViewHolder();
viewHolder.catchImage = (ImageView)convertView.findViewById(R.id.catch_image);
viewHolder.catchSpecies = (TextView)convertView.findViewById(R.id.catch_species);
viewHolder.catchStar = (ImageView)convertView.findViewById(R.id.catch_starfavorite);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder)convertView.getTag();
}
convertView.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
//Perform an action when this list item is clicked
}
});
viewHolder.catchStar.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//You can also have buttons within your list item that can be clicked
//independently of the parent list item.
}
});
//Set the rest of your views
return convertView;
}
}
I didn't have to do anything to my adapter; onListItemClick() just miraculously worked on its own for some reason. I'm scratching my head even more right now.
Incidentally, I extended CursorAdapter, not SimpleCursorAdapter, which I understand is sort of different. From what I read, CursorAdapter extension requires only overriding the newView() and bindView() instead of the usual getView() based on this http://www.workreloaded.com/2011/02/android-extending-cursoradapter-for-custom-listview/.

I'am trying to click a button on my list view to update that row first of all I tried to click on the item in the list view to show toast.
I did setOnItemClickListener of the ListView
public class Medlistview extends Activity{
DB db = new DB(this);
ImageButton updateimagebutton = (ImageButton)findViewById(R.id.editbuttonimage);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.medlistview);
populatemedlistview();
}
public void populatemedlistview(){
Cursor cursor = db.getMEDINF();
String[] medinfo = new String[]{
DB.col1,DB.col2,DB.col3,DB.col4,DB.rowID
};
int[] mappingmed = new int[]{
R.id.MEDid,R.id.MedName,R.id.Medpurpose,R.id.medNotaplet,R.id.ROWID
};
SimpleCursorAdapter medcursoradapter = new SimpleCursorAdapter(this,R.layout.medlistviewxml,cursor,medinfo,mappingmed);
ListView medlistview = (ListView)findViewById(R.id.listViewmed);
medlistview.setAdapter(medcursoradapter);
medlistview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(Medlistview.this,"clicked",Toast.LENGTH_LONG).show();
}
});
}
}
I made sure that my list view is clickable and focusable but still not working
One more thing I already define image button on layout item not on ListVew layout every time I run the app, is crashing and showing that null reference message in the log-cat do I need to define the button also on the ListView layout.

Thanks in Advance.
Implement View.OnClickListener() to your ImageButton in getView() method in your adapter, not in Medlistview activity. And use callback or eventBus to work with click action in your activity.
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.recycler_view_item, parent, false);
holder.tvName = (TextView) convertView.findViewById(R.id.tvName);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.tvName.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Button was clicked
}
});
return convertView;
}
Set
android:focusable="false"
android:focusableInTouchMode="false"
for all UIs controls in your custom layout file.
use android:descendantFocusability="blocksDescendants" inside listview,
check out this answere: can't click on listview row with imagebutton
Set the parent layout of the item
android:descendantFocusability="blocksDescendants"
and set
android:clickable="false"
android:focusable="false">
on all your widgets.
As I'm new to Android, I'm struggling to design a custom layout which is going to be my listview row. I like my list view row should contain title description, details and footer. My listview row hold data like the image I attached. Please see the attached image
You must need to create your_layout_row.xml first
<?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="60dp"
android:orientation="horizontal"
android:layout_margin="14dp"
>
<LinearLayout
android:layout_width="60dp"
android:layout_height="60dp"
>
<ImageView
android:id="#+id/imageView"
android:layout_width="wrap_content"
android:paddingLeft="10dp"
android:layout_height="60dp"
/>
</LinearLayout>
<TextView
android:gravity="center_vertical"
android:paddingBottom="10dp"
android:paddingRight="5dp"
android:id="#+id/textView"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_gravity="center_vertical"
android:layout_marginLeft="20dp"
android:text="TextView"
android:textStyle="normal|italic"
android:textSize="17dp" />
</LinearLayout>
now here you have your listview layout.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#color/TaskList_layout_background_color"
>
<ListView
android:id="#+id/lv_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="5dp"
android:dividerHeight="10dp"
android:paddingBottom="5dp"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:paddingTop="5dp" >
</ListView>
</RelativeLayout>
now create your class Model
for example :
class ModelClass
{
String text;
public ModelClass(String _text)
{
text = _text;
}
public String getText()
{
return this.text;
}
}
now create your custom adapter class
public class CustomAdapter extends ArrayAdapter<ModelClass> {
// declaring our ArrayList of items
private ArrayList<ModelClass> objects;
/* here we must override the constructor for ArrayAdapter
* the only variable we care about now is ArrayList<Item> objects,
* because it is the list of objects we want to display.
*/
public CustomAdapter(Context context, int textViewResourceId, ArrayList<ModelClass> objects) {
super(context, textViewResourceId, objects);
this.objects = objects;
}
/*
* we are overriding the getView method here - this is what defines how each
* list item will look.
*/
#Override
public View getView(int position, View convertView, ViewGroup parent){
// assign the view we are converting to a local variable
View v = convertView;
// first check to see if the view is null. if so, we have to inflate it.
// to inflate it basically means to render, or show, the view.
if (v == null) {
LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = inflater.inflate(R.layout.your_layout_row null);
}
/*
* Recall that the variable position is sent in as an argument to this method.
* The variable simply refers to the position of the current object in the list. (The ArrayAdapter
* iterates through the list we sent it)
*
* Therefore, i refers to the current Item object.
*/
ModelClass i = objects.get(position);
if (i != null) {
// This is how you obtain a reference to the TextViews.
// These TextViews are created in the XML files we defined.
TextView tt = (TextView) v.findViewById(R.id.textView);
// check to see if each individual textview is null.
// if not, assign some text!
if (tt != null){
tt.setText( objects.get(position).getText());
}
}
// the view must be returned to our activity
return v;
}
}
now in your main activity set your listview adapter to this customAdapter.
ArrayList<MyModel> myList = new new ArrayList<MyModel>();
myList.add("1");
myList.add("2");
myList.add("3");
myList.add("4");
ListView myListView = (ListView)findViewById(R.id.lv_list);
CustomAdapter adapter= new CustomAdapter(acitivity, 0, myList);
myListView.setAdapter(adapter);
In this case, you have to custom adapter.
Actually Relative is more suitable for designs. But now I'll write with LinearLayout to be easy.

Even scrolling is not working.
I am unable to figure out why is this happening? Am I missing out something?
Any help in resolving this is appreciated.
The following will do the job in your case.
ListView propertylistview = (ListView) findViewById(R.id.listview);
propertylistview.setOnItemClickListener( myListViewClicked ):
OnItemClickListener myListViewClicked = new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(YourActivity.this, "Clicked at positon = " + position, Toast.LENGTH_SHORT).show();
}
};
Dont forget to remove the following from the CustomAdapter
convertView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(parent.getContext(), "view clicked: " + ListArray.getName(), Toast.LENGTH_SHORT).show();
}
});
If the touch events are getting intercepted inside the cell layout, in the layout for your custom cell, set
android:descendantFocusability="blocksDescendants" on the top level layout of your cell. For me, it was too much of a pain to add xml attributes to every individual view.
Note that this can also be set in code:
cell.setDescendantFocusability(FOCUS_BLOCK_DESCENDANTS);
I also tried this with a ListView inside a cell, and I had to override onTouchEvent to get it to work:
public class NoTouchListView extends ListView {
#Override
public boolean onTouchEvent(MotionEvent ev) {
return false;
}
}
the simple code that solved my problem, and method view.setOnClickListener be within my custom adapter
view.setFocusable(false)
Check your list row layout once :
layout or any view should not be `android:clickable="true" and
android:focusable="true"
if it is there just delete and run the application again.
Even I was having the same problem, I am having checkbox, did the following to masker itemClickListener work,
Added the following properties to the checkbox,
android:focusable="false"
android:focusableInTouchMode="false"
android:clickable="false"
and ItemClickListner started working.
For detailed example you can go through the link,

Hope it helps Cheers!!
For TextView you should also use
android:textIsSelectable="false"
https://developer.android.com/reference/android/widget/TextView.html#setTextIsSelectable
When using a custom layout for an item in listview, it turns out that OnItemClickListener does not fire.
Previously, I was using android.R.layout.two_line_list_item. All I did was swap out this deprecated layout for my own custom layout.
I have tried:
-setting the choice mode to single
-enabling long and short clickability in the parent list and list items
-enabling focus and descendant focusability
-requesting focus
Any Feedback would be greatly appreciated!!!
Thank you!
I am guessing you can try setting android:clickable="true" in the customlayout's xml file. But the code of your layout file could be more helpful.
Here is the custom layout...
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:focusable="false"
android:focusableInTouchMode="false" >
<TextView
android:id="#+id/itemSummary"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:focusable="false"
android:focusableInTouchMode="false"
android:textIsSelectable="true" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toLeftOf="#id/itemSummary"
android:focusable="false"
android:focusableInTouchMode="false"
android:orientation="vertical" >
<TextView
android:id="#+id/item"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="false"
android:focusableInTouchMode="false"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textIsSelectable="true" />
<TextView
android:id="#+id/subItem"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/item"
android:focusable="false"
android:focusableInTouchMode="false"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textIsSelectable="true" />
</RelativeLayout>
</RelativeLayout>
Here is some view item creation code...
adapter = new ArrayAdapter<ComplexObject>(this, R.layout.item_row, 0,
al) {
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = inflater.inflate(R.layout.item_row, parent,
false);
}
ComplexObject item = adapter.getItem(position);
((TextView) convertView.findViewById(R.id.item)).setText(item
.getShape());
((TextView) convertView.findViewById(R.id.subItem))
.setText(item.getWeight() + " lbs");
((TextView) convertView.findViewById(R.id.itemSummary))
.setText(item.getAge() + " years");
return convertView;
}
};
i am working on an Android app that needs showing a list[table], inside the layout[view]
I come from iPhone dev objC land, and i have an app that shows a table[list] inside the view[layout]
So how to show a list inside my layout, and place it to specified location [center],
ps. I havent found a list in the graphical layout editor of the xml, where is the list[table]?
2. I have done some tests with list views, but is a view, that replace the xml view, i want it inside my xml,,
thanks a lot!
Yes, of course, you can do that
1) you need to have listholder.xml here, you can scratch anything in you layout view, either imageview, textview..etc. just don't forget to add ListView inside it. for example:
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/head_logo_bg">
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/background_label">
<TextView
android:id="#+id/city_txt"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:layout_gravity="center"
android:text="Sydney"
android:textStyle="bold"
android:textSize="17sp"/>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="40sp">
<ListView
android:id="#android:id/list"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_centerVertical="true"
android:scrollingCache="false"/>
</LinearLayout>
2) For custom your own list item, you have to create listitem.xml i.e.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/listitemone"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="10sp">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:orientation="vertical">
<ImageView android:id="#+id/user_image"
android:layout_width="80px" android:layout_height="80px"
android:layout_alignParentLeft="true"
android:layout_marginRight="5px"
android:src="#drawable/icon"
/>
</LinearLayout>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginLeft="5sp"
android:orientation="vertical">
<TextView
android:id="#+id/date_label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/date"
android:textStyle="bold"
android:textSize="16sp" />
<TextView
android:id="#+id/date_value"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignBaseline="#id/date_label"
android:layout_marginRight="20sp"
android:textColor="#FFF"
android:text="MM/dd/YYYY"
android:textStyle="bold"
android:textSize="16sp" />
</RelativeLayout>
</LinerLayout>
3) create customAdapter in your activity, it would look like this;
public class MyListActivity extends ListActivity {
private ArrayList<Yourdata> yourdata = new ArrayList<Youdata>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listholder);
// yourdata might be array, arraylist etc.
MyCustomAdapter listadapter = new MyCustomAdapter(this, R.layout.listitem, yourdata);
setListAdapter(listadapter);
}
private class MyCustomAdapter extends ArrayAdapter<Yourdata>{
//this case, i use Yourdata as type
private ArrayList<Yourdata> items;
public PreviousAdapter(Context context, int textViewResourceId,
ArrayList<Yourdata> items) {
super(context, textViewResourceId, items);
this.items = items;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if(v == null) {
LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.listitem, null);
}
Yourdata yt = items.get(position);
if(yt != null){
// Don't forget to use v.findView...., otherwise, it might force close when run app.
TextView dateStr = (TextView)v.findViewById(R.id.date_value);
dateStr.setText(yt.getDate());
}
return v;
}
}
}
P.S. the above code might not exactly right... just give you an idea :)
Here is a source about custom list (you might have seen it) hope it useful
