Android :: Passing An Order By Setting Variable

Jul 24, 2010

I have a list view with several columns; things such as name, date, etc. I want to be able to click on the header TextView and sort the list by that field. When the list loads the variable works, and a list is queried and sorted by the field _id (no surprise other than it works), but when i click on the header TextView I get a force close:

Thread [<3> main] (Suspended (exception SQLiteException))
ViewRoot.handleMessage(Message) line: 1757
ViewRoot(Handler).dispatchMessage(Message) line: 99
Looper.loop() line: 123
ActivityThread.main(String[]) line: 4595
Method.invokeNative(Object, Object[], Class, Class[], Class, int, boolean) line: not available [native method]
Method.invoke(Object, Object...) line: 521
ZygoteInit$MethodAndArgsCaller.run() line: 860
ZygoteInit.main(String[]) line: 618
NativeStart.main(String[]) line: not available [native method]

The TextView gives no errors when not changing my orderby variable.
Setting Variable:

private View.OnClickListener NameSortbtnListener = new View.OnClickListener(){
public void onClick(View v){
sort = " KEY_JOURNAL_TITLE ";
fillData();
} };

Populating List:
private void fillData() {
Cursor notesCursor = mDbHelper.fetchAllJournals(sort);
startManagingCursor(notesCursor);
String[] from = new String[]{journalDbAdapter.KEY_JOURNAL_TITLE,
journalDbAdapter.KEY_LOCATION, journalDbAdapter.KEY_JDATE,
journalDbAdapter.KEY_STEPS};
int[] to = new int[]{R.id.text1, R.id.text2, R.id.text3, R.id.text4};
SimpleCursorAdapter notes =
new SimpleCursorAdapter(this, R.layout.notes_row, notesCursor,
from, to);
setListAdapter(notes);
}

Query (In DB Adapter):
public Cursor fetchAllJournals(String sort) {
return mDb.query(DATABASE_JOURNAL_TABLE, new String[] {KEY_JROWID,
KEY_JOURNAL_TITLE, KEY_JOURNAL_NOTES, KEY_JDATE, KEY_LOCATION,
KEY_STEPS},null , null, null, null, sort ,null);
}

Android :: Passing Variable From One Class To Another

Nov 15, 2010

I am working to set a countdown timer. I have successfully (borrowed) a number picker (spinner) and set up the dialog box for the user to set the time. This is in a class called timepickactivity and the variables are hour and mins (R.id.hour and R.id.mins). I want to call the set values (R.id.hour and R.id.mins) from the dialog (timepickeractivity) to the actual countdown class (countdown) but I can't figure out how to get the values.

Passing Variable From One Class To Another

Feb 20, 2012

I would like to setup a boolean called dFlag in the main.class of my program and reference it in another class.

I already have it setup to work locally just hitting a snag on how to do it.

Code:
public class Main extends Activity {
boolean dFlag; ///Debug flag, true=enabled | false=disabled
}
public class Other extends Activity {
if(dFLag = true) {
///Output debug message
}
}

Or is there an easier way to do what I want without having to re-invent the wheel so to speak?

Android :: Passing Variable String To Create Arrays (Android)

May 24, 2010

I am a newb to Android and Java and want to write a funtion that will display a list based on a varable that I pass to the function. The function is below and the code below creates an array out of a string called type, but what I want to do is pass it a variable string and have it build a list based on that string. So if I wanted the type list I would say list_it("type")But if I try something like getResources().getStringArray (R.array.thelist); it doesn't work.Can someone point me in the right direction? public void list_it(String thelist){String[] types = getResources().getStringArray(R.array.type); ArrayAdapter<String> mAdapter = new ArrayAdapter<String>(this, R.layout.list_item1, types);
setListAdapter(mAdapter);
ListView lv = getListView();
lv.setTextFilterEnabled(true);

Android :: Setting Z Order Of View With BringChildToFront

Sep 18, 2010

I'm trying to set the z order of a UI element (i.e. a View) so that it will overlap another element, but calling ViewGroup.bringChildToFront() has a weird side effect....it moves the element to be the last item in the parent (the ViewGroup). Is this a bug, expected behavior, or what? More importantly, how can I set the z order or a View without this unfortunate side effect?

Android :: Changing Variable Affects Indirect Variable (value Vs Reference)

Sep 26, 2010

Is copying the reference to the object and not the value of the object. Meaning, when I modify pos.top or pos.bottom, the original object gets modified. I'm guessing I am missing a concept of pass object by reference vs value here which I thought I understood. What is the fix here? Is it a problem with how I defined my custom class?

Android :: Passing An ArrayList Of Objects

Nov 12, 2010

Is there a way to pass an Array List of objects between activities? The myObject implements Parcelable and I'm able to successfully pass the objects around individually, but that means I need to have an exact amount of "myObjects" coded. I want this to dynamically grow/shrink by what the user does with the app. I have seen some posts on the web about doing:

Activity A
ArrayList<myObject> myObjArray = new ArrayList<myObject>();

Then when passing this into the intent I would use:
intent.putParcelableArrayListExtra("myObjArray", myObjArray);

Activity B
ArrayList<myObject> myObjArray = new ArrayList<myObject>();
Bundle extras = getIntent().getExtras(); myObjArray = extras.getParcelableArray("myObjArray");

However, the myObjArray always gets filled with "null". How can I achieve this?

Android :: Passing ArrayList Across Activities

Apr 7, 2009

I have an ArrayList<MyList> aList in an activity. I would like to send this data to another activty. Such that,
ArrayList<MyList> aList;
Intent intent = new Intent(); intent.setClass(mainactivity.this, newActivity.class); intent.putExtra("MyList", aList ); startActivity(intent);

On the receiving activity,
Intent i = getIntent(); newList = (ArrayList<MyList>) i.getSerializableExtra("MyList");
But this gets me no where. ERROR! My intention is to share this List between activities.

Android :: Passing Values With Intents

Nov 17, 2010

I have searched and searched and I just can't get this code to work. I have a main.xml layout and a setting.xml. I have some values I would like the Settings.class to change in my main apps class.Three string to be exact. I have tried this simple test code in my main app class.

settings.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
Intent intent = new Intent(v.getContext(), Settings.class);
startActivityForResult(intent, 0);}});

//Then a function
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent){
super.onActivityResult(requestCode, resultCode, intent);
Bundle extras = intent.getExtras();
String value = extras.getString("myKey");
if(value!=null){
Log.d("hmmm",value);}}}

In my settings.class I have the following
returnHome.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent.putExtra("myKey", "YEAH");
setResult(RESULT_OK, intent);
finish();}});

Back in main app class it is not getting logged. Like I said I have three string in the main class that I want settings class to change and send back.

Android :: Passing Values From One Activity To Another

Feb 11, 2010

I have an app which makes use of several layout-views. Every layout - view also got a class for it, which extend the Activity class. One class for example retrieves some database values whilst offering a search form to the user. Afterwards the user can select one of those values and he gets presented with another screen which gives similar options as the one selected. Anyways, I'd like for the first Activity to be able to send an array with data (Strings for example) to the second one. Right now I show an activity by using:

Intent i = new Intent(this, activitysName.class); startActivity(i);

I have no idea whilst using this construction how I can "initialize" the new object with the String array I want to pass to it. So how should this be achieved ? Should I be using something else instead of an Intent-Activity combination ?

Android :: Passing Intent Value To Another Class

Oct 14, 2010

I have four groups in a listview each with four url's I want to load in a webView. When the user select a url to goto I set a value like so;

if (position == 0) webb = webb +2;
{
Intent intent = new Intent(this, official.class);
startActivity(intent);
}

I then carryout the intent to move to the webView class where I have given each URL a value like so;

if (webb == 2) mWebView.loadUrl("http://yahoo.com");
if (webb == 3) mWebView.loadUrl("http://www.bbc.co.uk");

But the screen stays blank, if I state the value inside the official.class it works. How can I get this value to pass to another class based on the selection the user makes from the listview.

Android :: Passing Intent Value From One Class To Another

Oct 16, 2010

I have been trying to get "getExtra" to work but without success, I have a listview with 4 choices which launch a webpage within a webView class, when the user selects the option lets say option 3 I want to pass the value of 3 to the webView class so that it will load the correct webpage, at the moment I get no errors, but the app force closes when I select the option, could this be due to having to announce this in the manifest? can somebody help with where I am going wrong. This is my intent

public void onListItemClick(ListView l, View v, int position, long id) {
if (position == 0) {
Intent intent = new Intent(this, official.class);
intent.putExtra("weburl", 3);
startActivity(intent);}
This is the official class:
public class official extends Activity {
int number = getIntent().getIntExtra("weburl", 0);
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
mWebView.goBack();
return true;
} return super.onKeyDown(keyCode, event);
} WebView mWebView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.browser1);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
if (number == 2) mWebView.loadUrl("http://bcafc.livewwware.co.uk");
if (number == 3) mWebView.loadUrl("http://www.bbc.co.uk");
mWebView.setWebViewClient(new HelloWebViewClient());

Android :: Passing Bitmap To Another Activity

Jun 7, 2010

I have a Bitmap image and i want to forward the bitmap to another activity. I have two activities Activity A and Activity B. This is how I started the Activity B
startActivityForResult(new Intent(Activity A.this, Activity B.class), 120);
in activity B
private void forwardImage(Bitmap bit) {
Intent i = new Intent(MMS.this, Compose.class);
i.putExtra("MMS", bit);
setResult(RESULT_OK, i);
finish(); }

This is not forwarding to Activity A but if I put a String to the intent it'll forward. This is how I listen to result in Activity A

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
// super.onActivityResult(requestCode, resultCode, data);
switch (resultCode)
case RESULT_OK: Intent intent = getIntent();
Bitmap bitmap = (Bitmap) intent.getParcelableExtra("MMS");
mmsImage.setImageBitmap(bitmap);
default: break;
} }

How can I pass a bitmap.

Android :: Passing Parameters To New Activity

Mar 2, 2009

I'm programming an Activity that launches a second one through startActivity just like in the Forwarding example. The main difference is that I'd like to pass some data to the second Activity when starting it, for example an item selected in a list owned by the first Activity. I can't find how to do that. Am I missing something? I guess I do.

Android :: Passing An Array To A View

Apr 8, 2010

My background is in C, but I'm relatively new to Java and to Android. I have a question as to whether I'm implementing code in the best way:

As a learning exercise in Java and in meeting the Model-View- Controller pattern, I wrote a simple game. It plays out on a 2D grid owned by the game class, and is drawn to the display by an extended View class. I have it working, but I'm wondering after the fact if I'm going about it the right way.

Here's a simplified version of what I have:

Android :: Passing A Service Handler

Aug 9, 2009

I've read the android AIDL documentation and have a general idea of how RPC works between an Activity and a Service. However, for my application it seems overboard to implement such features: basically, I want to pass a Service a nice handler so its thread can pass data to my Activity. Currently I'm getting around this by using a static public member (a hack) but I would prefer just passing a Handler object in the Service's starting Intent. However since a Handler isn't serialize-able , I haven't found a way to pass it to the service without a simple static member hack. Any insight? Or, am I just going to have to suck it up and do a formal RPC to the service?

Android :: Best Practice - Passing Id To New Intent?

Sep 22, 2009

I am creating a database driven app for managing people. I am showing a list of people with each name in a TextView. When a TextView is clicked, I launch a new intent to show the detail for the person. My question: What's the best practices for passing the id of the person to the new intent? The TextView is displaying the name of the person, so how do I know the id of the person? Once I know the id, I know how to pass it to the new intent, but I don't know what the best way to associate the id of the person to the TextView. Is there a best practice for this?
