Is it possible to add custom menu items in the native Contact list ?
I mean when the user selects a user from his contact list, is it possible to add a custom action there ? ( for those who are familiar with Blackberry development, something similar to the MenuItem class )

View 1 Replies View RelatedOk I have been trying to figure this out for a while. I have an application that needs to read images from a folder created by the application on the sdcard. I have no idea what the names of the files are because the user specifies the names of the files. I need to read the images from the folder and make something like the default image viewer, where you can share them delete them and things like that. Im thinking read them into a grid view first but 1) cant figure out how to dynamically read them from a folder 2) how would I implement the image options like the default viewer? If there was a way to open the default viewer on a certain folder that would help.
Anyways any input would be amazing been working on it for a while.
I'm pretty new to Android dev and still working out a lot of things.I've got a main menu showing using the following code, but can't work out how to disable selected items in the menu. Can anybody help me with some sample code?
View 2 Replies View RelatedI am designing an application which requires Drag&Drop functionality to transfer items from one list to another.
Is there any way to drop item into another list, as i have seen applications to drag and drop items in the same list(Reordering the list)?
I have an Android app where users can add items to a ListView, and I'd like them to be able to re-order the items in the list however they want (as opposed to just offering them different sort orders). It's easy enough to add a position setting for the items (they come from the DB) but what kind of UI elements are available for the user to indicate the desired ordering? Is there a pattern anyone has seen implemented for this? I have not seen anything on Android that does anything like this, except the home screen which is similar but looks a little bit beyond my expertise at this point. The best I can think of is to use a long click and context menu to "move up" or "move down". Any better ideas?
View 2 Replies View RelatedI have a list where i basically need a hierarchy of items. Any children of an item would be padded slightly, as to easily distinguish their parent item. How could this be achieved? Note that i could, if needed, make each parent show no children, and then when the parent is clicked, a new list containing all of it's children is loaded. This however requires more clicking to display information than i would prefer. Also, the items themselves will contain graphics and whatnot (to show a drag'n'drop button, etc), so it would be best if it visually appeared as if the item itself had a margin, rather than the contents of the item being padded.
View 1 Replies View RelatedIn Android, I want to present the user with a list. When an item on the list is selected some action is performed, and this list item is no longer selectable. It is also 'grayed out' or the like to indicate that it cannot be selected the next time the list is displayed. I have seen the isSelectable() override in Adapter, but I believe this causes the item to be treated as a separator, which causes visual problems. And I have not found a way to 'gray out' an item.
View 4 Replies View RelatedI want to build a list that show the directory tree like list similar to folders view on the left pane in 'Windows Explorer'. I have seen ExpandableList but this goes into 2 levels only. I want to go into multiple levels. Expand the item by clicking on the left icon and show sub directories in it. Click on sub directory expand icon, show the sub-sub diretories in it and so on.
View 4 Replies View RelatedI need an advice. What is the best way to implement in android a list of such UI elements (see the ref)A list contains a lot of such elements (about 30-40). I'm using now relative layout and 4 text fields and I think it isn't a good way.I think it's too heavy (full list will contain: 30 relative layouts and 30*5 = 150 text fields).

View 1 Replies View RelatedI have a list view and an adapter that sets alternating background colors to the list items ("zebra" list style):
public View getView(final int position, View convertView, ViewGroup parent) {
int colorPos = position % colors.length;
...
convertView.setBackgroundColor(colors[colorPos]);
return convertView;}
But now, when i select an item using scroll wheel, or when I click an item, the original colors for selecting/clicking do not override my custom backgrounds (I can see the original color below the one I set).
How can I set the original colors for these states?
I cannot find any example of a widget showing a scrollable list of items (e.g. text) since the widget api says there is no listview, no scrollview etc.. at all, how to implement a scrollable list inside a widget?
For example a list like friends-stream from HTC shows or many other widgets around.... do i have to code my own list-implementation for a widget.
The 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 have a listview from an SQLDatabase using custom CursorAdaptor. I would like to go back to the activity that I used to create the items when I click on them in the listview. So that I can edit the entries. But nothing happen when I implement the OnItemClick method and the getItemId() on the CursorAdapter even though am not sure I am correct there. Here is my Code:
public void onItemClick(AdapterView<?> adapview, View view, int position, long rowId) {
Cursor c = adapter.retrieveRow(rowId); // retrieve row from Database
Intent edit = new Intent(this,NewItem.class);
edit.putExtra(DBAdapter.KEY_ID, rowId);
edit.putExtra(DBAdapter.Title, c.getString(c.getColumnIndex(DBAdapter.Title)));
edit.putExtra(DBAdapter.DATE, c.getString(c.getColumnIndex(DBAdapter.DATE)));
startActivity(edit); } public long getItemId(int id){ return id; }
I've got the following main.xml:
<?xml version="1.0" encoding="utf-8"?> <AbsoluteLayout
android:id="@+id/widget0" android:layout_width="fill_parent"
android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android" >
<ListView android:id="@+id/listview" android:layout_width="315px"
android:layout_height="379px" android:layout_x="2px" android:layout_y="50px" >
</ListView> <TextView android:id="@+id/title" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:text="Select device:" android:textSize="17sp"
android:layout_x="-2px" android:layout_y="1px" >
</TextView> <Button android:id="@+id/refresh" android:layout_width="109px"
android:layout_height="wrap_content" android:text="Refresh" android:layout_x="209px android:layout_y="7px" >
</Button> </AbsoluteLayout>
The main class does nothing but drawing the layout. I've got the following class and layout for the listitems:
<?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" >

import android.app.ListActivity; import android.os.Bundle;
import android.view.View; import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener; import android.widget.ArrayAdapter;
import android.widget.ListView; import android.widget.TextView;
import android.widget.Toast;
public class BTListView extends ListActivity {
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, COUNTRIES)); ListView lv = getListView();
lv.setTextFilterEnabled(true); lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// When clicked, show a toast with the TextView text
Toast.makeText(getApplicationContext(), ((TextView) view).getText(),
Toast.LENGTH_SHORT).show(); } } ); }
Countries is just an array with a list of countries, some dummy values. Now, how do I make the list items of the BTListView class go in the ListView (with @+id/listview) of the main class? Now my list works, but it isn't clickable anymore. This is the code:
ListView lv = getListView(); lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// When clicked, show a toast with the TextView text
Toast.makeText(getApplicationContext(), "lolwat", Toast.LENGTH_SHORT).show();
} } );
Can any one please tell me how to add multiple items (images/text) in list view?

I am trying to compose a list with some items expandable and some single items.

Should I use something other than a string array?What is the best way to do this?

I want to display the same options menu on all of my application's activities. I created a generic Activity that implements the menu, and all my further activies extend it. The problem: when I need to extend other specific activities, like ListActivity and MapActivity, I can't figure out how to extend the generic activity and add the List or Map behaviour to the new class. To deal with the issue I had to create three different generic activities, each extending Activity, ListActivity and MapActivity.I've tried creating an abstract activity but it doesn't work, I would need to extend two classes at the same time. I could try interfaces but since I can't implement methods, I would have to paste the menu implementation all over the second-level classes, right?

View 1 Replies View RelatedWhen your intent kicks knocked on the head by the OS and then restored / recreated (for example when you slide out the keyboard on the G1) if you have a ListView populated with items in an activity they appear after the recreate. However, if you have a dialog box full of list items and do the same steps, the ListView comes back up empty when the window is redrawn after the slide.
Is this an Android bug? My list is a pain in the neck to pack into a bundle, it consists of Address objects, and there might be ten of them. Am I doing something "un-android?" I'm thinking of just dimissing the dialog when this happens. But calling dismiss in onRestore (for the dialog) doesn't seem to work.
