I recently started an Android project as some sort of tutorial, but rather than the same boring List/Web View most android offline tutorial app make use of, I decided to make a it a bit better using Recycler View and card View.
The main problem so far(even it may not be to the end user as long as the app works anyway) is putting the text in cardview(had no problem with images and other res) as my strings.xml is filled up and everything looks rough.
<resources>
<string name="lesson_galaxy_one_intro"> <h1><span style="color:red">Welcome to My ..... Course</span></h1>]]> </string>
<string name="lesson_galaxy_two_intro"> <![CDATA[

<string name="galaxy_one_main_neration"> <![CDATA[<h1> <span style="color:red"> ]]> </string>

This is more of my first real project, I just want to ask how do developers package their Text. Is strings.xml the right option for apps that require many texts? Please any tip could be helpful.

I want to allow the users to enter in text using the settings template in android studio.
And display this in a textview.(which is already set)
settings_activity_settings.xml
is
<resources>
<string name="title_activity_settings">Settings</string>
<!-- General settings -->
<string name="pref_header_general">General</string>
<string name="pref_title_display_name">Enter Team 1</string>
<string name="pref_title_display_name_2">Enter Team 2</string>
</resources>
how to i retrieve this data
First of all your approach is not correct.
Because, you can't change resource files during runtime. Strings are hard-coded in the string.xml file and hence can't be changed during runtime.
I suggest you read this, it will help you understand why android framework don't want you to edit the file in runtime.
Now, the solution to your problem? Simple, save the string you get from user in to Shared Preference and load it int text views from there.
This code is stored in res/values/strings.xml
<string-array name="planets_array">
<item>एक काम</item>
<item>दो काम</item>
<item>तीन काम</item>
<item>चार काम</item>
</string-array>
The array will be passed onto ArrayAdapter which will be used in Navigation Drawer.
However, I want these Items to be referenced using an english name.
EDIT
This code was done according to changes suggested by Dave.
<resources>
<string name="Mercury">एक काम</string>
<string name="Venus">दो काम</string>
<string name="Earth">तीन काम</string>
<string name="Mars">चार काम</string>
<string name="app_name">Navigation Drawer Example</string>
<string-array name="planets_array">
<item>#string/Mercury</item>
<item>#string/Venus</item>
<item>#string/Earth</item>
<item>#string/Mars</item>
<item>Jupiter</item>
<item>Saturn</item>
<item>Uranus</item>
<item>Neptune</item>
</string-array>
<string name="drawer_open">Open navigation drawer</string>
<string name="drawer_close">Close navigation drawer</string>
<string name="action_websearch">Web search</string>
<string name="app_not_available">Sorry, there\'s no web browser available</string>
</resources>
When I tap on first four items, the respective images of planets dont show up in Navigation drawer but when I tap on last 4 Items (Starting from Jupiter) , It works fine
You can set the name attribute for each item but you will have to parse the strings.xml file and use getValue from the available set of attributes. Check this SO question out :
Get name attribute of item of string array
I haven't had the time to try this though.
It's already answered here.
As the Android reference says:
<item>
...
The value can be a reference to another string resource.
...
Solution:
First, you have to write simple string elements with your english name:
<string name="english_planet_1_name">एक काम</string>
<string name="english_planet_2_name">दो काम</string>
<string name="english_planet_3_name">तीन काम</string>
<string name="english_planet_4_name">चार काम</string>
And then you can reference them everywhere, even from string-array items:
<string-array name="planets_array">
<item>#string/english_planet_1_name</item>
<item>#string/english_planet_2_name</item>
<item>#string/english_planet_3_name</item>
<item>#string/english_planet_4_name</item>
</string-array>
Finally you get both: your planet local names and their english reference name.
All of a sudden I'm getting 80+ R cannot be resolved to a variable errors after modifying my strings.xml file. I'm not sure exactly what I've done to cause the issue but I've wrecked my project somehow and when I check the network drive where my workspace resides - the strings files is there and I can open it in eclipse and see the supposed "missing strings" however eclipse states: No resource found that matches the given name regardless of the fact the strings are infact there.
Steps taken:
Clean the project
Examine strings.xml for abnormalities (none found)
Restart Eclipse

There's a redundant closing </string> tag on the last entry and no closing tag for tryagain_text3. Other than that, have you checked that the file is XML valid?
In android app, within that app has settings option such as English and Tamil
If user select Tamil, with in the app only display in Tamil, in all activities all labels should in Tamil. if the user select English all labels are changed to English. How to make that?
Please give any idea....
Follow this Link: Android : translate the language of whole app on click
Then Do like this, Add the string values for each locale into the appropriate file.
English (default locale), /values/strings.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="title">My Application</string>
<string name="hello_world">GoodMorning</string>
</resources>
Tamil, /values-tl/strings.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="title">My Application</string>
<string name="hello_world">Kaalai vanakkam</string>
</resources>
Link: http://developer.android.com/training/basics/supporting-devices/languages.html
Have a look at this question.
Basically you have to put the translated Strings in a folder in the res folder.
While I am working with help of tutorial I found this in textview android:text-"#string/hello" it shows some error.
Then I went through graphical view and right click the component and enter the text. Then that error removes and notifies me that
**Hardcoded string hello should use String resources**
In android, "#string/" refer to the string.xml in Project>res>values> location in your package explorer.
String.xml contains a xml file which refer to a string with an id.
Eg:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="hello">Hello World</string>
<string name="app_name">My app</string>
</resources>
Here name="hello" is the id & "Hello World" is its value. When #string/hello is used, the value will be shown.
Similar is the case with "#drawable/". It will refer to the images used. and many more.
You can set text in text view programmatically. Eg:
TextView tv = (TextView)findViewById(R.id.text1); //text1 is the id u provide in xml file
tv.setText("Hello World");
I hope it helped you.
#string/hello simply notice Android to load the String in a XML file located into the /values directory (strings.xml).
hello is the ID of the String specified by name="hello" into that XML.
Android Studio is very unstable. Previously, it auto generated the corresponding statement in the string.xml . Tutorials using previous versions get beginners stuck because of that.
How string.xml works
Android Studio expects you to write all texts in one place, in the string.xml file. In all other files, you just put abbreviations. e.g.
android:text="#string/Hello_world"
means that find the abbreviation Hello_world in the string.xml file and replace it by the intended text.
In string.xml, the corresponding statement which should be written is:
<string name="Hello_world">Hello world!</string>
and that should do the job!
It is possible to just write android:text="Hello world!" (This is what hardcoding is). If you intend to be an android dev, then you would not maximize efficiency.
Why? string.xml
Having all texts in one file eases many things. Like translation if needed and easy change. However, you should choose meaningful abbreviations!
