Android :: Updating TextView Values

Apr 9, 2009

Hello everyone, and thanks in advance for the help. What I'm trying to do is a relatively simple task, but one that doesn't seem to be working. What I'm trying to do is display the Orientation X,Y,Z coordinates on the screen in basic TextView boxes. The sensors are constantly updating my Global.myOrientation float array, and then I'm running a Timed thread (I'm very new to threading, so forgive me if it's ugly, but it gets the job done almost). In this thread I just set the value of each TextView's text to the desired value. The problem is that it only seems to work the first time.

It correctly displays whatever my initial data is, but then subsequent runs of the thread do nothign to update the onscreen values when I change the orientation of the phone. LogCat output shows me that inside the run() method, the values of Global.getOrientationX,Y,Z are being updated correctly, and that the right data is being passed to TextView. How can I get around this limitation of TextView being initialized once and then immutable?

Any assistance in fixing this, or providing an alternate solution would be greatly appreciated. Code posted below:

Android :: How To Update TextView On Button Click With Spinner(s) Values

Jun 14, 2010

I am trying to populate a TextView based on the current selected options in 3 Spinner(s) but cant seem to figure out how to retrieve the selected values from the Spinners to invoke the update function with.
Here is my current code (quite messy but I'm just learning Java,
public class AgeFun extends Activity {
private String[] dayNames;
private String[] yearArray;
private final static int START_YEAR = 1990;
private static TextView textDisp;
private Button calcButton;
private static Spinner spinnerDay, spinnerYear, spinnerMonth;
private static ArrayAdapter<?> monthAdapter, dayAdapter, yearAdapter;
private int year, month, day;
/** Called when the activity is first created. */
@Overridepublic void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
year = 2000;
month = 1;
day = 1;
textDisp = (TextView) findViewById(R.id.textView1);
calcButton = (Button) findViewById(R.id.button);
calcButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// Perform action on clicks
AgeFun.updateAge(year, month, day);
// Month spinner
spinnerMonth = (Spinner) findViewById(R.id.spinnerFirst);
monthAdapter = ArrayAdapter.createFromResource(
this, R.array.monthList, android.R.layout.simple_spinner_item);
monthAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinnerMonth.setAdapter(monthAdapter);
// Day spinner
dayNames = new String[31];
for(int i =1; i <= 31; ++i)
{ dayNames[i-1] = Integer.toString(i);
} spinnerDay = (Spinner) findViewById(R.id.spinnerSecond);
dayAdapter = new ArrayAdapter<CharSequence>(this, android.R.layout.simple_spinner_item, dayNames);
spinnerDay.setAdapter(dayAdapter);
// Year spinner
yearArray = new String[40];
for(int i =0; i < 40; ++i)
{ yearArray[i] = Integer.toString(START_YEAR+i);
} spinnerYear = (Spinner) findViewById(R.id.spinnerThird);
yearAdapter = new ArrayAdapter<CharSequence>(this, android.R.layout.simple_spinner_item, yearArray);
spinnerYear.setAdapter(yearAdapter);
updateAge(2000,1,1);
}private static void updateAge(int year, int month, int day) {
Date dob = new GregorianCalendar(year, month, day).getTime();
Date currDate = new Date();
long age = (currDate.getTime() - dob.getTime()) / (1000 * 60 * 60 * 24) / 365;
textDisp.setText("Your are " + Long.toString(age) + " years old");

General :: Android Resetting User Values And Updating Software Constantly

Jun 14, 2012

The device in question is a Dynavin car stereo that runs the Android platform.

I have updated the ROMS and even roll backed to older versions but this issue persists. I am now using a totally modified ROM created by a user on here for my device.

My issue is, every 5 or 6 boot ups of my device all my settings seem to revert to default. Well not "all" but I will explain in further detail.

When my issue arises, google maps/navigation/mail will not load, it will crash and go back to the home screen.Google PLAY will revert to Google Market, when I log into market, it will update all google programs.Once updated, maps/navigation/mail all work perfectly fine.

My installed programs are unaffected to the extent that they do not need updating, however, all their settings which I adjust, revert back to normal, all the dialogue boxes return, its like as if I'm running the program for the first time again.

When there is no issue, the system works fine and requires no updates etc.I feel it may be something to do with the ROM? Should files be moved to the memory card to preserve certain settings? But if I do that, how will Android know where to find these files?

Android :: Textview On Left Side With Button On Right Side Non Absolute Values

I'm trying to get my textview to hug the left side of the screen while the button hugs the right side (and if possible just for ocd sake have the text view center itself vertically to be in line with the button) but not do it using absolute values.I thought layout_gravity took care of what I'm trying to do but apparently not.

Android :: Android - Updating TextView String Through AIDL Service

Aug 12, 2010

I have an app that uses a TabHost. Several of the Tabs share a common HUD. I am using a service to periodically update those values by calling an AIDL function when ready.

However, since several of the Tabs are using the same HUD I would like to abstract that part out.

I thought about having the HUD.xml use a String resource as it's value and then the abstracted class can update the String resource. However, apparently Android can not update String resources programatically.

The only alternative solution I see would be using SharedPreference.

I have concerns accessing a Database everytime the value is refreshed.

Motorola Droid X :: Widgets Not Updating / Stop Updating

Jul 24, 2010

Anyone having trouble with widgets stop updating? Like my clock/calendar/weather/news/pretty much any widget i have stops updating after an hour. So i look at my clock widget two hours later and it is an hour behind. Happens to ALL my widgets.Even the quick turn on/off wifi,bt,gps and such. They just stop updating/showing animation.I have ADW launcher installed. I am wondering if it is that. I do not really want to remove it as i hate the stock 3 button interface at the bottom (why do i need a contacts and phone, just use the phone to look thru contacts, wasted space IMO) and am quite keen on keeping the 5 button.Any ideas? If i power off the phone and turn it back on it's fine again for about an hour. SOmetimes randomly thru the day it will start updating and working fine again then randomly stop again.

Android :: Android RelativeLayout - Trying To Vertically Center A TextView When The TextView Below Has No Text

Jul 14, 2010

I have a ListView that contains an Image on the left of two vertically-oriented TextViews using a RelativeLayout. When both TextViews have text it looks fine. Sometimes the TextView on the bottom won't have any text, and the problem is that the entire layout is several pixels above where it should be because it still reserves that space for text when there isn't any making the entire list have annoying blank gaps. I remember seeing an example of where someone made the layout not reserve the space, but I can't remember how he did it.

Jan 4, 2014

I'm trying to create a textView in the parent activity onActivityResult but the textView does not appear. There is an ImageView that takes up the whole parent activity. I can create a textView and place it, and it should go on top of the imageView?

In the parent class:

Intent chooseClothesIntent = new Intent(this, ChooseClothesActivity.class);
chooseClothesIntent.putExtra("menuId", menuId);
startActivityForResult(chooseClothesIntent, 1);
}[/HIGH]

[Code]...

then in my new activity:

[HIGH]@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
try {
ClothingItem ci = mListContents.get(position);
String imagePath = ci.getImagePath();

Android :: How To Divide TextView Into 2 Seperate TextView In Android

Nov 15, 2010

I have a problem with TextView in Android

I am making an application like Facebook. In m.facebook.com, when I open it I see they do one thing specailly.

(Alice) is writing on (BackStreetBoy1010938920) wall

Because the width of Mobile screen is small so the real message like tha

(Alice) is writing on (BackStreet

Boy10101009393) wall

I guess they use TextView for (BackStreetBoy1010938920) but I can't do like this.

private String imagePath;
private String mediaPath;

public String gettitle()

Android : Way To Store Values?

Apr 6, 2010

That's a lot of code... no time to read it over now.. but off the top of my head: look into either using a database, an Application class (that will run the whole time your app is alive), or adding extras to the Intent bundle before starting your subactivity. These are all methods to pass data around 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 :: Extending Themes - How To Put New Values?

May 8, 2010

I have trouble (example<http://groups.google.com/group/android-developers/browse_thread/threa...>) wrapping my head around styles/themes. Can somebody help me or point me to actual documentation?

Let's say I have a drawable that I want to use as the background of a layout:
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle>
<gradient android:startColor="#9F9FA4" android:endColor="#66FFFFFF" android:angle="270" /> </shape>

Now I want to have a dark and a light theme. Depending on the chosen theme I want to have a different value for startColor and endColor. How do I do that? I am aware of extending themes, but what do I put into the items? How do I reference those new values then?
