I'm using the following code from the apidemos..

Under /* User clicked Yes so do some stuff */, i'm not fed the isChecked variable.. however, I am given isChecked in the /* User clicked on a check box do some stuff */ section.. Obviously i don't want to update my SharedPrefs on checkbox click, in case the user hits cancel..So how do I get the checkboxs and values on the setPositiveButton onClick ?

Android :: AlertDialog.Builder Vs Class To Extend AlertDialog - Application Size

Mar 12, 2010

I am trying to figure out what is the best way to go about creating dialogs. I can either create my own Dialog class (which, to me, is more clean and organized), or I can use AlertDialog.Builder (which would be done inline, and funky looking)... What are the positivies and negatives of either implementation?

Android :: Padding List Items?

May 31, 2010

I 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.

Android :: List With Grayed Out Items

Aug 7, 2009

In 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.

Android :: List Items With Alternating Colors

Jan 12, 2010

I 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?

Android :: Two Selectable Items In Each List In ListView

Dec 16, 2009

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.

Android :: Editing List Items In ListView

Sep 2, 2010

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; }

Android :: Displaying List Items In ListView

Oct 16, 2010

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" >
</TextView> package com.android.bluetoothp2p;
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();
} } );

I am trying to change the text color of the spinner list items individually. I would like to be able to color the top three texts black and then the bottom four grey. This way the last items look disabled, but I still want to be able to capture the event when they are chosen. I haven't been able to find any documentation on how to do that. Alternatively I would like to disable som list items, but still be able to capture the event when they are chosen.

Android :: Create List With Only Certain Items Expandable?

Jun 8, 2010

I am trying to compose a list with some items expandable and some single items. I wish to have it so that when either a single item or expandable list child is clicked, I can call an intent based on the text of the item.I suppose expandable lists would work, but is there a way to set items in an expandable list so that they don't have the expandable list icon? Should I use something other than a string array?What is the best way to do this?

Android :: Dialog Box Full Of List Items Not Appearing

Jun 8, 2009

When 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.

Android :: How To Assign Each List Items An Individual Icon?

Oct 24, 2010

I'm very new to Android and Java development, searching and reading various tutorials and using different parts of code from around the internet, trying to make sense of it as I go. Currently I have a list created with 4 list items, what I'd like to do is assign a different icon to each of these list items, however, I've no idea how to do it, nor do I know what to search for. Here's the code:

main.xml
<?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:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/mainListView"> </ListView>
</LinearLayout> row.xml
<TextView xmlns:android="http://schemas.android.com/apk/res/android
android:id="@+id/rowTextView" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:padding="10dp" android:textSize="16sp" >

</TextView> FirstList.java
import java.util.ArrayList; import java.util.Arrays;
import android.app.Activity; import android.os.Bundle; import android.widget.ArrayAdapter; import android.widget.ListView; public class FirstList extends Activity {
private ListView mainListView; private ArrayAdapter<String> myListAdapter;
/** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main);
mainListView = (ListView) findViewById( R.id.mainListView);
String[] myList = new String[] {"List 1", "List 2", "List 3", "List 4"};
ArrayList<String> listObjects = new ArrayList<String>();
listObjects.addAll( Arrays.asList(myList));
myListAdapter = new ArrayAdapter<String>(this, R.layout.row, listObjects);
mainListView.setAdapter(myListAdapter);
} }
