[android-developers] Dynamic array ListView problem
Hi guys,
I am experimenting with locations and listviews. I am getting location
results back and I am trying to create a listview of my locations
results using the following code:
ListView locationList =
(ListView)findViewById(R.id.ListView01);
String[] items = new String[]{};
try {
Geocoder geocoder = new
Geocoder(this, Locale.getDefault());
List addresses =
geocoder.getFromLocation(LATITUDE,
LONGITUDE, 5);
address_textview.setText( ""+addresses );
Address[] addresses_array = new
Address[addresses.size()];
addresses.toArray(addresses_array);
for( int i = 0; i < addresses_array.length; i++ ){
items[i]=
addresses_array[i].getPostalCode();
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
ArrayAdapter adapter= new
ArrayAdapter(this,
R.layout.list_item, items);
locationList.setAdapter(adapter);
My problem is, when I try to write into my items array ( items[i] =
addresses_array[i].getPostalCode(); ) in the forloop, my application
crashes.
Can anyone please help. I am stuck at this point.

Thanks for responding. If you mean we are supposed to drag elements into place, I got ta say ... It simply does not work. I have an existing project with a very complex layout in one of my views. Any attempt to reorganize the layout by dragging things around ends in disaster. Please help. Important projects are on hold until I can convinitenly do comple layouts again.

[android-developers] OOP objects + complex view
Hi guys, I am developing an app that need to display information on the stock of a store. Each activity will have upto 100 items. My plan is to layout this information in a 10 * 10 grid. Each box in the grid represents an item of stock. Each of these items will be represented by an icon and a piece of text beneath the icon (the name). I setup a new layout which has an ImageView and a TextView for this. I called the layout Tab.xml So, I need to know if it is possible to write a java class which will use the Tab.xml as the layout. Then I can programmatically create each java class item, setting the image and text as I go along. Can anyone please give me some direction about this? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

As normal, I call my dialog by showDialog(DATE_DIALOG_ID);
The log message Log.e("TRACKING", "reaching#2"), is never logged.

[android-developers] Re: Fetch Spinner value outside setOnItemSelectedListener
Hey, thanks for the clarification.
As for the EditViews, I am using the following code:
final EditText input_field = (EditText) findViewById(editViewINT);
if( mGameSettings.contains(preference) ){
input_field.setText(
mGameSettings.getString(preference, "does not
exist") );
//Toast.makeText(QuizSettingsActivity.this, "Exists
with value : "
+ input_field.getText() , Toast.LENGTH_SHORT ).show();
}
/*
* implementing the nickname input
*/
input_field.setOnKeyListener( new View.OnKeyListener() {
@Override
public boolean onKey(View v, int keyCode,
KeyEvent event) {
// TODO Auto-generated method stub
String processed_input =
input_field.getText().toString();
Editor editor =
mGameSettings.edit();
editor.putString(preference,
processed_input);
editor.commit();
//Toast.makeText(QuizSettingsActivity.this, "checking :
"+preference, Toast.LENGTH_SHORT ).show();
return false;
}
});
}
So the input is set in a sharedpreference and writing that value back
into the EditView whenever the activity is "restarted".

[android-developers] Re: Fetch Spinner value outside setOnItemSelectedListener
Hi, thanks for your continued assistance. Perhaps it would be better if you saw my app in action. Would you mind downloading it from http://www.icerge.com/sites/default/files/TriviaQuiz.tar_.gz It's harmless and only takes text input and remembers them when the app is closed and reopened ( reload the activity ). The first two EditText fields will take some input and remember that input for the next visit. ( Please ignore the 2 following buttons ). The spinner is right at the bottom of the view. Open it and select any option. Then click the "menu" button on the phone. It should give you 2 options ( Settings and Help ). Please select "setting". The view will reload. Whatever input you may have put into the 2 EditViews at the top are retained but not the previously selected value on the spinner - which is what I have been trying to deal with.

[android-developers] Re: Fetch Spinner value outside setOnItemSelectedListener
Thanks for responding. I have the following code:
final Spinner spinner = (Spinner)findViewById(R.id.Spinner_gender);
spinner.setOnItemSelectedListener(
new AdapterView.OnItemSelectedListener() {
public void
onItemSelected(AdapterView parent, View
itemSelected, int selectedItemPosition, long selected){
Editor editor =
mGameSettings.edit();
editor.putLong(GAME_PREFERENCES_GENDER,
selectedItemPosition);
editor.commit();
}
@Override
public void
onNothingSelected(AdapterView arg0) {
// TODO Auto-generated
method stub
}
}
);
ArrayAdapter adapter =
ArrayAdapter.createFromResource(this,
spinnerID, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
if( mGameSettings.contains(GAME_PREFERENCES_GENDER) ){
Toast.makeText(QuizSettingsActivity.this,
"Detected(again): " +
spinner.getSelectedItemPosition(), Toast.LENGTH_SHORT).show();
spinner.setSelection( spinner.getSelectedItemPosition()
);
}
Towards the end, I am checking that a sharedPreference value is set
and simply printing the selectedIndex in my Toast.
But, the very next line I am using the same function call but my
spinner does not set to the previously selected value when the
activity is re-loaded.
However, if I simply give spinner.selection a static argument, e:g 2,
it works fine upon re-loading the activity.
I don't know why it won't work ... please help!

Hey, please do excuse my ignorance. Based on you very suggestion, I wrote the following code : Toast.makeText(QuizSettingsActivity.this, "Detected(again): " + spinner.getSelectedItemPosition(), Toast.LENGTH_SHORT).show(); spinner.setSelection( spinner.getSelectedItemPosition() ); Please enlighten me as to why the getSelectedItemPosition() function displays the currently selected value in my toast but as I try using it in my seSelection call, my spinner never sets to the value confirmed in my above toast ? I also tried assigning the getSelectedItemPosition() return value to a variable and giving it to the toast and the setSelection function as well as casting the return value to an integer .. didn't resolve my problem.

[android-developers] Fetch Spinner value outside setOnItemSelectedListener
Hi guys,
I have a spinner successfully working but I am trying to use the
spinner.setSelection method to "remember" the previous spinner value
when the activity is reloaded.
Outside of setOnItemSelectedListener, is there a function of the
spinner that can give me the selected index?
The following code is my function code to both setup the spinner and
then my attempt to set the spinner with the index previously selected:
private void setSpinner(int spinnerID){
final Spinner spinner =
(Spinner)findViewById(R.id.Spinner_gender);
int spinner_value;
spinner.setOnItemSelectedListener(
new AdapterView.OnItemSelectedListener() {
public void
onItemSelected(AdapterView parent, View
itemSelected, int selectedItemPosition, long selected){
spinner_value =
selectedItemPosition;
Editor editor =
mGameSettings.edit();
editor.putLong(GAME_PREFERENCES_GENDER,
selectedItemPosition);
editor.commit();
Toast.makeText(QuizSettingsActivity.this, "selected:
"+GAME_PREFERENCES_GENDER+"("+ spinner_value +")",
Toast.LENGTH_SHORT).show();
}
@Override
public void
onNothingSelected(AdapterView arg0) {
// TODO Auto-generated
method stub
}
}
);
ArrayAdapter adapter =
ArrayAdapter.createFromResource(this,
spinnerID, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
if( mGameSettings.contains(GAME_PREFERENCES_GENDER) ){
spinner.setSelection(spinner_value);
}
}
All I am trying to do here is use spinner_value to remember the
selected index so I can set the spinner to that index.
However, the spinner_value is never holding the desired value at
spinner.setSelection(spinner_value); in the last lines of code

[android-developers] Re: Remembering Shared Preferences
Really sorry my message was not very detailed. I'm learning Androis and so I confused about a number of things. PLEASE - download my small sample app from here : http://www.icerge.com/sites/default/files/TriviaQuiz.rar When you start the app you will see the "View Scores" screen, hit the "menu" button and select "settings". The "settings" activity is where the problem is. Now, the nickname EditText is where the problem is. As I understand it, when you enter text and hit return, the code is supposed to check if GAME_PREFERENCES_NICKNAME is set. If it isn't, it is set in the SharedPreferences and if it was previously set output it into the EditText box. So, I enter a nickname and hit return but the text reverts to "INPUT NICKNAME" which was the temporaying in EditText label. Also, when I press menu and settings again, my previous entry is not in the EditText box as I expect it to be. The code is in QuizSettingsActivity.java, the SharedPrefernces information is set in QuizActivity.java and the layout is settings.xml. I would really appreciate your help. I am a bit lost. Thanks.

[android-developers] Remembering Shared Preferences
Hi guys,
I am using the following code to set the input from an EditView in a
SharePreference.
But I am also trying to read the input back into the EditView.
final EditText input_nickname = (EditText)
findViewById(R.id.EditText_Nickname);
input_nickname.setOnKeyListener( new View.OnKeyListener() {
@Override
public boolean onKey(View v, int keyCode,
KeyEvent event) {
// TODO Auto-generated method stub
if(
mGameSettings.contains(GAME_PREFERENCES_NICKNAME) ){
Toast.makeText(QuizSettingsActivity.this, "Exists",
Toast.LENGTH_SHORT ).show();
input_nickname.setText( mGameSettings.getString(GAME_PREFERENCES_NICKNAME,
"") );
}else{
String processed_nickname
= input_nickname.getText().toString();
Toast.makeText(QuizSettingsActivity.this, "Not Exists",
Toast.LENGTH_SHORT ).show();
Editor editor =
mGameSettings.edit();
editor.putString(GAME_PREFERENCES_NICKNAME, processed_nickname);
editor.commit();
}
return false;
}
});
The problem is, when I revisit the activity, the EditView never
contains the text I input the last time. I actually contains the above
TextView content and I can't then edit it.
I know that's not really clear but does anyone have any ideas to help
with seting and retrieving shared preferences properly ??

[android-developers] Re: TextView visibility problem
You are right. When I move the TextView up it is squashed but visible. Can you advice on how I can make it visible beneath the relative layout On 20 Oct, 03:22, metal mikey wrote: > It might be because the TextView is positioned offscreen.

[android-developers] ListView problem
In following a tutorial from "SAMS Android Application Development in
24 hours" I hit a problem with my first ListView example.
Basically, my java code is firing according to log messages I set but
my ListView does not display when I execute my app. The App runs fine
without crashing so syntactically all seems to be well.
Since I can't attach documents, please bear with me as I paste some
code but you can download the entire sample app from
http://www.icerge.com/android-sample-app-download
My layout file is called Menu.xml and is as below:
http://schemas.android.com/apk/res/
android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
The java file is called QuizMenuActivity.java and is as follows:
package com.androidbook.triviaquiz;
import android.os.Bundle;
import android.util.Log;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class QuizMenuActivity extends QuizActivity {
private final String LOGID = "Track";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.menu);
Log.i(LOGID, "Begining!");
ListView menuList = (ListView)
findViewById(R.id.ListView_Menu);
/*String[] items=
{ getResources().getString(R.string.menu_item_play),
getResources().getString(R.string.menu_item_scores),
getResources().getString(R.string.menu_item_settings),
getResources().getString(R.string.menu_item_help) };*/
String[] items ={"test#1","test#2","test3","test#4"} ;
ArrayAdapter adapt = new ArrayAdapter(this,
android.R.layout.simple_list_item_1, items);
menuList.setAdapter(adapt);
Log.i(LOGID, "Reaching this point!");
}
}
Finally, there is a Menu_item.xml which defines my TextView that the
java file above attempts to write array data to. It is as follows:
http://schemas.android.com/apk/res/android";
android:layout_width="match_parent"
android:text="testing testing"
android:layout_gravity="center_horizontal"
android:shadowRadius="5"
android:gravity="center"
android:textColor="@color/listview_items_color"
android:shadowDx="3"
android:shadowDy="3"
android:textSize="@dimen/menuxml_item_size"
android:shadowColor="@color/listview_items_color_glow">
As I don't want to overwhelm you with code you will have to take my
word for it that all the resources are in place and are not the
problem.
Can anyone offer some insight? Please download the app from
http://www.icerge.com/android-sample-app-download to examine the code
better and see what I mean.
Thanks.
