Android :: Loading String Values From File Instead Of List In Class

Nov 1, 2010

I think I have a pretty easy problem to solve, but I have been beating my head against the wall for hours trying to get past it! I have an adapter that loads a list of URLS:
adapter=new MyAdapter(this, lStrings);
list.setAdapter(adapter);

The list of URLS looks like this:
private String[] lStrings={
"http://www.domain.com/file1.jpg",
"http://www.domain.com/file2.jpg",
"http://www.domain.com/file3.jpg",
};

What I want instead is to load these values from a text file that lies on the SD card. For that matter, I would be okay with loading the values from a text file into a String, and then load the String into the list as I imagine that would be the "cleaner approach". However, all attempts to do this have failed. For instance, I replaced the above snippet with this:

private String[] lStrings=
{ MainActivity.this.getString(R.string.myurllist) };
but then I get a Forced Close on loading.

I'm a bit new to Java, Android, and development in general.

Android :: Strange ListView Loading / Default Values Displayed

Jun 24, 2009

I have a listview that is populated by a couple threads that pull in data from the network. Before that data comes in, there are some default values displayed. When the screen loads, there are 6 items displayed, each with the default data. The 1st (index 0) loads and is updated on the screen, and then number 6 (index 5) is updated with that same info. Then, item 2 (index 1) loads, and then item 5 (index 4) mirrors that data. Then item 3 loads, then item 4 reloads with the correct data, then then item 5 with the correct data, then item 6. Why are items 5 and 6 briefly showing the data from other elements in the list? I can't figure out what in the world could be causing this.

Android :: Switching Between Landscape And Portrait Mode Makes Intent Lose Values / What's Cause?

Feb 25, 2009

I am using Intents to switch between activities in my Android app. I am putting data in the Intent for use in the next activity. When I switch the phone between landscape and portrait modes, the values passed from the intent are lost and I get a NullPointerException.

Can someone please tell me what could be wrong.

There's a lot of code to post it entirely. But if someone needs to look at specific parts of code, I can post it here.

Edit
I solved the issue of state not being saved. But another problem I faced is that none of the buttons on the screen work after the orientation has been changed. On button press, I get this warning in LogCat

Android :: Loading Activity Darkens Screen - Loading Screen

Nov 2, 2009

I've looked through the documentation and I can't seem to figure out how to have the screen blured/greyed when I select an activity that may take a while to load.

This seems to be an Android standard (both the Camera app and the Camcorder app do it when first selected), but I don't see any documentation on it. I even tried looking through the source of these apps on git, but couldn't seem to find it.

Android :: Getting Values From Array

Apr 16, 2010

I have a collection of strings and declared the strings individually as arrays using ArrayList<String> al=new ArrayList<String>(); and called the arrays in the program by using al=getIntent().getStringArrayListExtra("titles");

Now, instead of declaring each of the arrays i have created SongsArray.java like below...

public class SongsArray {
private String title;
private String movieName;
private String singerName;
private String imagePath;
private String mediaPath;

public String gettitle()
{
return title;

Android :: Getting Values From XML - API Level 3

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 :: Why Getting Same Values Of Different JSON Date?

Apr 16, 2010

I do not know the reason why am i getting same values of different JSON date values. Here is my code for parsing date values in JSON date format:

package com.jsondate.parsing;
import java.text.SimpleDateFormat; import java.util.Date;
import android.app.Activity; import android.os.Bundle; import android.util.Log; import android.widget.TextView;
public class JSONDateParsing extends Activity {/** Called when the activity is first created. */String myString;
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView tv = new TextView(this);
//Date d = (new Date(1266029455L));
//Date d = (new Date(1266312467L));
Date d = (new Date(1266036226L));
//String s = d.getDate() + "-" + d.getMonth() + "-" + d.getYear() + d.getHours() +
d.getMinutes() + d.getSeconds();
// SimpleDateFormat sdf=new SimpleDateFormat("yyyy MMM dd @ hh:mm aa"); //Toast.makeText(this, d.toString(), Toast.LENGTH_SHORT);
Log.e("Value:", d.toString());
myString = d.toString();
String []words = myString.split(" ");
for(int i = 0;i < words.length; i++)
Log.e("Value:", words[i]);
myString = words[2] + "-" + words[1] + "-" + words[5] + " " + words[3];
tv.setText(myString);
setContentView(tv);
} }

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 :: 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?

Android :: Multiple Alarms With Different Values Of ID

May 16, 2010

I am setting multiple alarms like this, with different values of id. Multiple calls to AlarmManager.setRepeating deliver the same Intent/PendingIntent extra values, but I supplied different ones.

AlarmManager alarms = (AlarmManager)context.getSystemService(
Context.ALARM_SERVICE); Intent i = new Intent(MyReceiver.ACTION_ALARM);
// "com.example.ALARM" i.putExtra(MyReceiver.EXTRA_ID, id);
// "com.example.ID", 2 PendingIntent p = PendingIntent.getBroadcast(context, 0, i, 0);
alarms.setRepeating(AlarmManager.RTC_WAKEUP, nextMillis, 300000, p); // 5 mins

And receiving them like this:
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(ACTION_ALARM)) {
// It's time to sound/show an alarm
final long id = intent.getLongExtra(EXTRA_ID, -1);
The alarm is delivered to my receiver at the right times, but often with EXTRA_ID set to the wrong value: it's a value that I have used at some point, just not the one that I wanted delivered at that particular time.

Android :: Getting Compass Values And Use It On Map Overlay

Sep 13, 2010

I have a marker on the map using an Overlay. I also have access to the compass sensor which I'm able to show a textView with the orientation values (0 to 359). How can I apply this values to the marker? (which is a drawable). I already have a MAtrix created but when I insert the orientation value gives me an error, here it is:

GeoPoint geopoint = new GeoPoint((int) (newLocation.getLatitude() * 1E6),
(int) (newLocation.getLongitude() * 1E6)); Paint paint = new Paint();
Point pt = new Point(); mapView.getProjection().toPixels(geopoint, pt);
Bitmap bmp = BitmapFactory.decodeResource(getResources(),R.drawable.user2);
Matrix matrix = new Matrix(); matrix.postTranslate(-25, -25);
matrix.postRotate(direction); matrix.postTranslate(pt.x, pt.y);
paint.setAntiAlias(true); paint.setFilterBitmap(true);
int width = bmp.getWidth(); int height = bmp.getHeight();
Bitmap changedBitmap = Bitmap.createBitmap(bmp, 0, 0, width, height, matrix, true);
BitmapDrawable icon = new BitmapDrawable(changedBitmap);
icon.setBounds(0, 0, icon.getIntrinsicWidth(), icon.getIntrinsicHeight());
userOverlay useroverlay = new userOverlay(icon); useroverlay.addItem(item);
mapView.getOverlays().add(useroverlay);

I used the value retrieved from the sensor on "direction" but it doesn't work.

Android : Way To Get Realtime Gps Values While Not In A Mapview?

Jul 8, 2009

I was wondering if it is possible to start the gps receiver on the phone if the current activity is not a mapactivity. I am displaying a listview and when I start the gps I get the last location found correctly, however the gps indicator never appears on top of the phone's display even if I wait or restart this activity. The location of the gps stays the some. The gps indicator appears on top only if I enter an activity where a mapview is displayed. If I wait in the map activity for a little while then If I go back to my other activity and request the location there, then the location is updated with the last value that it had before exiting the map view. It never gets updated If I move around after that, though..
