I want to have an element in my preference menu that does the following: Show a list of options. Many are selectable Maximum amount of options to be chosen 2. Possibilities I thought of: Doing a separated PreferenceScreen and showing options as checkBoxes but I don't know where to place the logic of max 2 options. Extending DialogPreference and doing it by hand.

I'm making a image gallery with infinite vertical and horizontal scrolling. I put images inside a ListView to make a column, and put the ListViews inside a TableRow. However, it seems that child views of TableRow is not selectable and as a result I can't select the images in my ListView (easily). Is there a way to pass the events down to child views of TableRow so they can be selectable?

View 1 Replies View RelatedThe way I want it is, per row there will be a text and is followed by a right arrow button, so that the user can click on that button to edit the content of that row. If the user is using the keypad, by using the left and right buttons on the keypad, he should be able to select the textview or the Button in that particular row. I have seen this in a couple of apps. The way I see that working on those apps appear as if they are maintaining two lists in parallel.
The reason i felt it this way is, if I am on row 1 of the list and if I press the right key on the phone keypad, then the right arrow button will get highlighted and now if I use the down key or if I keep pressing the down key, then the focus will scroll through that arrow button only as if that is an another parallel list constructed. I don't know if that is a good way to do it. I tried many for getting this to work, but couldn't succeed.

I am displaying an AlertDialog with a list of selectable items on my first page, choosing one item will load to another page, but the problem is that when I go back to first one I can no more see the AlertDialog.
View 2 Replies View RelatedI'm making a custom adapter so that I can display a list of items with icons which looks like the menu that comes up when you long click the home screen. For some reason though the list items are not clickable. The can be navigated to with the D-pad but they cannot be clicked in any way. I thought maybe the problem was with the AlertDialog I was using so I replaced a working adapter I had elsewhere but I have the same issue there. My adapter looks like this:
ArrayList<IconListItem> mItems; LayoutInflater mInflater;
public IconListAdapter(Context context, ArrayList<IconListItem> items) {
mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mItems = items;
} public IconListAdapter(Context context) {
this(context, new ArrayList<IconListItem>());
} public void add(IconListItem item) { mItems.add(item);
notifyDataSetChanged(); return item;
} public void remove(IconListItem item) { mItems.remove(item); notifyDataSetChanged();
} @Override public int getCount() { return mItems.size();
} @Override public IconListItem getItem(int position) { return mItems.get(position);
} @Override public long getItemId(int position) { return position;
} @Override public View getView(int position, View convertView, ViewGroup parent) { View view;
if(convertView == null){ view = mInflater.inflate(R.layout.two_line_icon_list_item, null);
} else { view = convertView; } IconListItem item = mItems.get(position);
TextView lineOne = (TextView) view.findViewById(R.id.firstLine);
TextView lineTwo = (TextView) view.findViewById(R.id.secondLine);
ImageView iconImage = (ImageView) view.findViewById(R.id.icon);
lineOne.setVisibility(View.VISIBLE); lineTwo.setVisibility(View.VISIBLE);
iconImage.setVisibility(View.VISIBLE); lineOne.setText(item.getText());
if (item.getSubtext() == null) lineTwo.setVisibility(View.GONE);
else lineTwo.setText(item.getSubtext());
if (item.getIcon() == null) iconImage.setVisibility(View.GONE);
else iconImage.setImageDrawable(item.getIcon());
return view; }
And the XML it's inflating:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="6dip" >
<ImageView android:id="@+id/icon" android:layout_width="wrap_content"

android:layout_weight="1" android:layout_height="fill_parent" >
<TextView android:layout_width="fill_parent" android:layout_height="wrap_content"
android:layout_weight="1"android:gravity="center_vertical"
android:id="@+id/firstLine" android:ellipsize="marquee" android:inputType="text" />
<TextView android:layout_width="wrap_content" android:layout_height="0dip"
android:layout_weight="1" android:ellipsize="marquee"
android:id="@+id/secondLine" android:inputType="text" />
</LinearLayout> </LinearLayout>
When I say they are not clickable, I mean that they items do not highlight in orange when I press them nor does onItemClick ever get called. In my code I have this, a different adapter for another purpose and it works perfectly
this.foos= foos; fa = new FooAdapter(this.foos); fooList.setAdapter(fa);
// View the details for an item when it is selected
fooList.setOnItemClickListener(new OnItemClickListener() {
@Override public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
Intent i = new Intent(MyActivity.this, MyOtherActivity.class);
i.putExtra("foo", ((fooAdapter)arg0.getAdapter()).getItem(arg2));
i.putExtra("list_position", arg2);
MyActivity.this.startActivityForResult(i, 0);
} } );
But when I swap out the first 3 lines for
IconListAdapter ila = new IconListAdapter(this);
ila.add(0, "Test 1", android.R.drawable.ic_menu_mylocation);
ila.add(0, "Test 2", android.R.drawable.ic_menu_edit);
ila.add(0, "Test 3", android.R.drawable.ic_menu_search);
groupList.setAdapter(ila);
I t stops working.
I'm trying to create a dialog with multi-column selectable textviews, please take a look to the uploaded picture http://docs.google.com/leaf?id=0BzltuZp0qfq0MDBiZjc1NDgtZmQ5ZS00YjQ2L...
In other words it should be looked like a standard ListView dialog but with two or more columns separated with a line.
I've tried using a GridView for this, but I haven't found a way to add separators between items.
I also tried to play with padding&bg color (result on the picture [url]) but I couldn't avoid the table bounds and problems with selection.
Is there a way to create such dialog and how?
I have a working ListActivity class. Each of the list item consists of an ImageView and a TextView. However, when I try to replace the ImageView with ImageButton, The list becomes unselectable. The onListItemClick or any other function no longer get called when press a list item (Although the track ball can still focus a list item, but nothing more can be done). I have searched the forum and also the internet and failed to find any such working example, apart from one guy reporting a similar problem but with no answer.Code...
View 6 Replies View RelatedWhen using a PreferenceActivity to do preferences, the PreferenceScreen can contain a ListPreference. A ListPreference has an array of keys and an array of values. But the PreferenceActivity only writes the values to SharedPreferences. How do I get the key of the item selected from the list? I would have thought this is pretty fundamental, especially if you want to translate your app.
View 13 Replies View RelatedI have a text view and I'm trying to make the text selectable. The docs say:
Quote:
Use setTextIsSelectable(boolean) or the TextView_textIsSelectable XML attribute to make this TextView selectable
But I can't get it to work I tried
Code:
Tv.setTextIsSelectable(true);
and I get
The method setTextIsSelectable(boolean) is undefined for the type TextView I tried
Code:
android:textIsSelectable="true"
in the xml and I get
No resource identifier found for attribute 'textIsSelectable' in package 'android'
As a work around to the issue where a list item isn't focusable if it has a focusable child item (a comment by Romain Guy was that this was intended behavior, for accessibility reasons) I simply filled the listItem with two children, each of which is focusable - There's nowhere to directly touch on the listItem anymore, just it's children.
For the most part this is a useable workaround, effectively invisible to the user, except for one thing- Although you can scroll by swiping without issue, touching to *stop* the scroll no longer works- I imagine because the child item is capturing the touch event and not passing it to the parent listitem, at least while the scroll is in effect.
Is there a known workaround for this? Perhaps someway to "pass the baton" of the touch event back up to the parent listItem, or a way to change my design?
BTW- I know there's some built-in functonality for single/multiple choice listviews (checkbox listviews) - That doesn't actually help in my case. The app is a contact list, and the row children are a relativelayout (populated with contact info) and a clickable phone icon (a one-touch dial for the contact), which needs to be visible or invisible depending on whether the stored contact has a phone number.
I'm using listpreference in my android app and getting my key values and all is well and works good (now that you guys have helped me) BUT - when my listpreference menus popup, they only contain a cancel button. Let's say the user is choosing between red, blue, and green. When the listpreference dialog first pops-up, the dialog only shows a cancel button. Because of that, the dialog disappears as soon as the user selects their choice. I would like it so that when the user chooses their setting, they see the radio button get highlighted and then they go ahead and click the ok button...but I don't have an ok button and can't figure out why.

I want to put a ListPreference in my preference screen. But all the examples I have found in Internet the content are loaded out of a xml and I need that de options in the ListPreference are dynamic and not previously defined (in a xml).

I have an XML preferences screen which is handled by addPreferencesFromResource. On it, there is a ListPreference, for which I want the summary to contain the current value of that preference. I think this would be a common requirement, as otherwise you could not see the present value of the preference without expending a click. I read that the summary field supports resource references, and I see that I can refer to preferences as android:summary="@+preference/prefname" in my ListPreference. Clearly this is why resource references would be supported in this field. However, when I try this, instead of the present value of prefname, the text "false" appears as the summary. Does anybody know how to display a current value without taking the seemingly ridiculous step of rewriting the entire (large) preference screen in Java?

This is my first Android app (which is a soft keyboard, with dvorak layout) and so far it has gone pretty smoothly (either because or despite working from the sample code). I've had some problems (with special/swedish characters) that I've managed to take care of, but this problem I can't figure out how to solve..
But when I click the list item to edit it, i get an empty dialog (Title and button is shown right and with the text I set in the xml- file, but no list, screenshot: http://i49.tinypic.com/2501p55.png ). I can't see any problem with the program code (which isn't many lines..) or the xml (the arrays are generated by the Android utils in Eclipse and the preferences is a mix of auto and manual). You can see both Java code and XML here: http://pastebin.com/m4c52c3a2 (titles etc in Swedish..) (I've also tried a EditTextPreference item, which seemed to work fine..) I have also looked at the log/output using adb, and can't see any problems there either, so I have no idea onto how to solve this.
I am resuing ListPreference for a setting which I store in the database. I do not want it stored in the preference file. How can I reuse ListPreference in such way that it does NOT save to SharedPreference file?
View 2 Replies View RelatedI have a settings menu that pops up and in it is a listpreference type menu. It is associated with a settings.xml file where there are 'array-strings' within it.

The list that I've made within my 'array-strings' contain the text red, green, and blue. Within my code, I would like to do something if the user has choosen red, something else if they choose blue, etc., etc. Would I use a 'case' statement or an 'if' statement?

View 2 Replies View RelatedI'm betting im missing one small thing. I've looked on the developer site and i've read some tutorials and i'm just not seeing what i did wrong. I'm trying to use a ListPreference to decide which sound to play on a button click. I have this at the top:
public String greensound;
Here's my OnClick code:
case R.id.green:
SharedPreferences prefs=PreferenceManager.getDefaultSharedPreferences(this);
greensound = prefs.getString("greensound", "gsone");
if (greensound == "gsone") {
mSoundManager.playSound(1);
} else if (greensound == "gstwo") {...................
I have a ListPreference with the entries and entryValues correctly set. When I go in the prefernces activity and change the value it successfully works (I added a Toast to output the value after changing the option to test). But when I do the following to compare it, it always executes the else statment when I change it everytime, even like above when I changed the ListPreference and the value was "bluesky" it still failed to execute the correct if statement. Here's the code I use to check the value of the ListPreference in the onResume():
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this)
String backgroundPref = prefs.getString("backgroundPref", "");
if(backgroundPref == "bluesky"){
mainLayout.setBackgroundResource(R.drawable.bluesky);
Toast.makeText(getBaseContext(), "Blue Sky", Toast.LENGTH_SHORT).show();
}else if(backgroundPref == "sky"){
mainLayout.setBackgroundResource(R.drawable.sky);
Toast.makeText(getBaseContext(), "Sky", Toast.LENGTH_SHORT).show();
}else{
mainLayout.setBackgroundResource(R.drawable.sunsetscene);
Toast.makeText(getBaseContext(), "Sunset Scene", Toast.LENGTH_SHORT).show();
}
The Toasts are there so I can double check which statement gets executed, and it always seems to be the else one. Am I having a bad day and getting something wrong?

View 3 Replies View RelatedI am trying to put together a modal box with a scrollable list of checkable items and an OK and Cancel button at the bottom for the user to select filters from. It seems the simplest way to do things like this in Android is to reuse API components (widgets, layouts, etc) and the closest one I can find to this looks to be the ListPreference, which basically does exactly what I want (I can even work with storing the data in SharedPreferences). The problem is that I'm not launching this modal box from a PreferenceActivity, but rather will be launching it from either of two activities: a ListActivity and a MapActivity.

I'm having trouble dynamically populating the list. I would like to populate ListPreference with values from an array adapter (which I'll create and populate with relevant bluetooth device names). If this were a spinner View, I could just call setAdapter(). However with the ListPreference object I can't figure out how to attach an adapter (findviewByID won't cast from View To ListPreference, so I can't even get a handle to the object). I would like to attach an adapter and then populate the adapter with values, which in turn would populate the ListPreference with values.
