Android :: Set On Item Click Listener Not Working On Custom
Oct 5, 2009
I have Implemented a custom ListView by extending LinearLayout for every row. Every row has a small thumbnail, a text and a check box. The list view is deployed properly and I can scroll and fling through it without any problems. But The ListView doesn't seem to respond to the setOnItemClickListener() at all, So I had to find a workaround by setting click listener in the getView of the Text inside every row which is obviously creating problem when I am trying to reuse the adapter. Does anyone have a solution?

after figuring out the earlier question 'Layout Question', now my OnItemClickListener, and ItemLongClick Listener(ContextMenu) have stopped working. With just the TextView it works fine Anyone have any ideas as to why this would stop working?

What I´m trying to do is to create a list (using a list view) of items (which are views inflated from the same layout) what must be clickable. At first I thought that all I had to do was to add an onItemClickListener to the ListView so if the used clicked on any of the views that composed this Item the listener would react. Well, I was wrong. I´ve tried a lot of things, including setting focus and focusontouchmode off for each of the views that compose the item´s view but it still doesn´t work. Any tips here? Can I archive this result? Oh, also ... this list view is in a dialog and the listener is in the activity that builds the dialog.

I'm just beginning Android development, and I'm working to get a Custom list view with a checkbox working. I've created a base class that extends Activity, Created an Adapter and overrode the getView() method to add the checkbox to the list view. I'm assuming I need to do this because I need something equivalent to didSelectRowIndexAtPath from Obj C to update my model. Please let me know if there's an alternate way of doing this too Code...

I've looked everywhere for a solution to this, but I can't figure out how to implement it. My OnItemClickListener was disabled somehow on my ListView rows, because I have an ImageButton in the row layout, which takes over the focus. There have been numerous questions I've found, but none of them have gotten me anywhere. I've checked this question, but I couldn't really make heads or tails of it. I just need a way to get the rows clickable so that I can detect when a row is pressed. Long press and focus work fine.

I have a ListView and an ExpandableListView inside of a TabActivity. I have overridden the setOnItemClickListener for the ListView. I have 2 tabs and one uses the ListView and the other uses the ExpandableListView. For some reason I cannot click on any of the items in the first ListView. If I change tabs to the ExpandableListView and then go back to the first tab it will then allow me to click on the items as usual. Any ideas on why this is happening. Is there some kind of weird focus thing going on? Code...

I have a tab activity with three tabs and I want to display a listview in each tab. The list populates correctly, but for some reason I can not get the context menu or itemclicklistener to recognize gestures on the listviews. Anyone have any ideas why this might be? Below is my onCreate method: @Override public void onCreate(Bundle savedInstanceState) { super. onCreate (savedInstanceState);setContentView (R.layout.armory_header); TabHost mTabHost = getTabHost(); mTabHost.addTab (mTabHost. newTabSpec ("1"). setIndicator ("Weapons"). setContent (R.id.page1)); mTabHost.addTab (mTabHost.newTabSpec("2").setIndicator( "Armor" ).setContent(R.id.page2))TabHost.addTab(mTabHost.newTabSpec("3").setIndicator("Accessories"). setContent (R.id.page3)) ; weapons = (ListView) findViewById(R.id.weaponlist); registerFor ContextMenu(weapons) ;weapons.setOn ItemClickListener (new OnItemClickListener(){ @Override public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {// TODO Auto-generated method stub listId = weapons.getId(); position = arg2; showDialog (DIALOG);armor = (ListView) findViewById (R.id.armorlist) ;register ForContext Menu(armor); armor.setOnItemClickListener(new OnItemClickListener(){ @Override public void onItem Click(AdapterView<?> arg0, View arg1, int arg2, long arg3) { // TODO Auto-generated method stub listId = armor.getId();position = arg2; showDialog(DIALOG);

I don't know exactly how to explain this problem, but I'll try. I have a ListView with several items. Each item has inside a TextView and two ImageView. I want the ImageView change when I click on them, and I want to open a context menu when I press for a long time into the ListView item.For the ImageView, everything works properly. For the whole item, I can show the context menu after a long press, but my problem is that the ImageView changes as well when I am pressing the TextView, for example.I hope you understand my problem. I think that all the children of a view are affected by an event in the parent, but I am not sure.

when I click on one item in the ListView that item's background changes to light gray, but when I continue to scroll through the list every 4th item has the background changed to light gray even though those other items have not been clicked. How do I make only the item I clicked be effected by the click?
ListView lv = (ListView) findViewById(R.id.resultsList);
lv.setAdapter(new ArrayAdapter(this, R.layout.resultitem, (String[])labelList.toArray(new String[labelList.size()])));
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View view, int position, long id) {
TextView tv = (TextView)view.findViewById(R.id.result);
tv.setBackgroundColor(Color.LTGRAY);
tv.setTextColor(Color.BLACK);

For example whe i position the drawable i just use setBounds. Is there a way to specify the x and y coordinates for an image button?

I have a click listener:
private OnClickListener onMyListener = new OnClickListener() {
public void onClick(View v) {
myMethod();
} };
And my Method:
private String myMethod() {
TextView tv = (TextView) findViewById(R.id.TextView1);
return (String) tv.getText();
}
When it calls this method, at tv.getText() it breaks in the debugger.
With this in the stack --
ViewRoot.handleMessage(Message) line: 1571
ViewRoot(Handler).dispatchMessage(Message) line: 99
Looper.loop() line: 123

As I mentioned in the email subject, I want to select an item (e.g. Department of Human Resource Management) in my ListView. And you can see that: I had try to use setClickable(true), setChoiceMode(ListView.CHOICE_MODE_SINGLE), setFocusable(true), setFocusableInTouchMode(true), no matter I use touch screen to click on the item or use the scroll ball on my mouse to select the item, it also doesn't work. Is there any mistakes in my coding? I hope someone can give me some ideas what I should do. because I am a beginner for developing Android application.
And the following is my coding: package com.example.abc;.............

Each row of my view look like that:.............
When I click on the ImageButton "arrow", I trigger a method than need the id of the row to perform. By ID I mean the value of the field "_id" of the corresponding record in database. I did not find a direct way to do it, but I think I can if I get the index of the row in the ListView. Again, I don't know how to get this index from a click to a childview.

My activity runs in simulator, and I use mouse to control it. When I select the item in listview by turning scroll wheel, the background of item becomes orange. But, when I "click" the item in listview, the item does not response to my action. You received this message because you are subscribed to the Google Groups "Android Developers" group.

I'm working on my first Android project, and I created a menu via the XML method. My activity is pretty basic, in that it loads the main layout (containing a ListView with my String array of options). Here's the code inside my Activity:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// allow stuff to happen when a list item is clicked..........

I need to set up a simple event listener to refresh a listview from once in a while. The problem is I don't know how could I generate an event.
I know that for events like key or button pressing I just need to implement the handler. But in this specific case I actually need to generate the event, which will be fired everytime another running thread of my app wakes up and refreshes it's list of news from a rss feed.
I've done everything, but got stucked in here. Can I get any suggestion or link with some more info on how to implement this?

I have a single screen with a bank of buttons below a ListView. Entries on the ListView light up in orange when I scroll so I assume that are selected. When I then press the "Delete" button I want the onClickListener to remove the currently selected entry. But getSelectedItemPosition() always gives me -1. If I can't hope to use the GUI controls in this way, please give me another way of getting the same result.I have even tried setting the onClickListener of the List View to store the index before the button is pressed (in case pressing the button unselects the entry) but even that is always -1 it seems.

I have button, which displays a Context menu. In the menu are few items (some of them are disabled - setEnabled(false)).
Which event is called when a user click on the disabled item? It's not onContextItemSelected nor onContextMenuClosed. But the menu is closed after the click.

Could anyone post or point me to an example of using custom items in a theme? I've created a theme that uses custom attributes as item names, and I want to refer to those items in the code. I can see the theme is working because it also sets the android:windowBackground color. As a concrete example, I want an inactiveColor item in my Theme.GreenWithYellow to use in onDraw methods in my Views. I think this would be the right mechanism to use to have multiple color schemes for application specific purposes, but I would be happy to entertain other approaches, too.

I created a custom OverlayItem class so that I could essentially have one kind of OverlayItem whose Drawable marker would set itself depending on the state of some data that I pass into it. I have attempted to accomplish this by, on my first attempt, utilizing the setMarker method within the OverlayItem class. Once that did not work I attempt to override the getMarker method and have it return the appropriate marker to represent the data. Both of these attempts ended with nothing being drawn on the map...however if they are commented out the markers draw just fine (except they of course use the default marker, which isn't what I want). Here is my code for my custom OverlayItem class (the commented out methods I have tried and they have not worked):
private class MyOverlayItem extends OverlayItem {
private Context mContext; private MyData mData;
public MyOverlayItem(GeoPoint point, MyData data, Context context) {
super(point, data.getWhat(), data.getWhere()); this.mContext = context; this.mData = data;
/*if(data.getTemp() > 200) this.setMarker(res.getDrawable(R.drawable.icon_data_hot_l));
else if(data.getTemp() > 100) this.setMarker(res.getDrawable(R.drawable.icon_data_neutral_l));
else this.setMarker(res.getDrawable(R.drawable.icon_data_frozen_l));*/ }
/*@Override public Drawable getMarker(int stateBitset) {
Resources res = this.mContext.getResources(); if(this.mData.getTemp() > 200)
return res.getDrawable(R.drawable.icon_data_hot_l); else if(this.mData.getTemp() > 100)
return res.getDrawable(R.drawable.icon_data_neutral_l);
return res.getDrawable(R.drawable.icon_data_frozen_l);
}*/ }
Is there a way to do what I am attempting to do or do I need to make a unique OverlayItem class corresponding to each state of my data?
