Android :: How To Set / Pass Values From One Screen (activity) To Another?
Sep 30, 2010How do you set/pass values from one screen (activity) to another? What I have in the R.layout.main view labeled Calculator contains the code for doing calculations. The main.xml contains the layout (view) of the main screen. I have created an options menu which has another screen which shows you setup (R.layout.setup). The dialogsetup.xml contains the layout (view) for it.
When you press the menu button, you get the options menu. If you select "Setup", then it will display the setup screen. Now what I need to do is take the values from the setup screen (radio button and text values) and place them in the main screen so that when you exit the setup screen and go back to the main screen, you can take those values and use them in your main code.

View 1 Replies View RelatedAndroid :: Preferences - How To Load The Default Values When User Hasnt Used Preferences-screen
Apr 22, 2010I am using a PreferenceActivity to let the user set some values. I am feeding it the xml file with the defined preferences.
I have set all the android:defaultValue="" for them.
When I start my application, I need the preferences, or if they are not set yet manually, I want the default values:
CODE:.................
However, when android:defaultValue="true" I still get false. So, it looks like the defaultValues set in the XML are not used anywhere but when initializing the preferences-screen.
I don't want to hardcode the default values in the getBoolean() method. So, is there a way get the default-values with only defining these in 1 place?

Apr 6, 2010That'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.

Nov 17, 2010I 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, 2010I 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, 2010I 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);

Android :: Updating TextView Values
Apr 9, 2009Hello 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, 2010I 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?
