android-resources

I just encountered with a problem that I don't know how to solve. It looks silly but I cannot find a way to fix it. I have a form in android with several EditText and when you submit the form it checks those EditText and if they have wrong data I change the EditText to red border (applying a ninepatch image). myEditText.setBackgroundResource(R.drawable.edittext_red); The problem is, I want to restore android's default style when the user change the EditText, but I don't know how to do it. if I do: myEditText.setBackgroundResource(0); It will just remove everything and that's not what I want.

I have a Listview with a custom adapter. I am getting the standard Your content must have a ListView whose id attribute is 'android.R.id.list' error, however, My ListView has an android:id="@android:id/list" value set. It's really doing my head in. Any suggestions? main.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" style="@style/Layout"> <ListView android:id="@android:id/list" style="@stlye/ListMenuView"></ListView> </LinearLayout> styles.xml <resources> <style name="Layout" parent="@android:Theme"> <item name="android

I'm following this solution to use enetities in my string resource file: Is it possible to do string substitution in Android resource XML files directly? I'm using an external file in the resource tree: /res/raw/entities.dtd , its content: <!ENTITY ent_devicename "MyDeviceName"> In the string.xml resource file: <!DOCTYPE resources [ <!ENTITY % ent_devicename SYSTEM "../raw/entities.dtd"> %ent_devicename; ]> <resources> <string name="name">The name is &ent_devicename;</string> </resources> but I get this error: The entity "ent_devicename" was referenced, but not declared. As you can see Android

This is in continuation to an answer which helped me on this post We can add the string resource as follows from build.gradle : productFlavors { main{ resValue "string", "app_name", "InTouch Messenger" } googlePlay{ resValue "string", "app_name", "InTouch Messenger: GPE Edition" } } It works like a charm and serves the purpose of having different app names per flavor. (with the original app_name string resource deleted from strings.xml file. But, how do we add localized strings for this string resource added from build.gradle ? Is there an additional parameter we can pass specifying the locale

I've found an unused string resource, like: <string name="obsoletestring">my name is null!</string> However it is in tens of files, of different languages, in different strings.xml files in values , values-af , values-be , etc folders. I must have missed something not to know any way to do this in Android Studio other than modifying it by hand one by one. tl;dr How to delete an unused string resource for all configurations? chrisonline It is now possible inside Android Studio. After Lint checks you see an option on the right Remove All Unused Resources ! To Delete a single string resource

I'm new to Android development, and I've been playing around with it a bit. I was trying to create a program that has a small database-like collection of never-changing data. In C#, my currently best language, I'd use a List of a custom class and serialize that to an xml file, then read that into my application at runtime. I found the /xml resource folder in Android, but I'm not sure how I would go about doing what I'm envisioning. What would be the best way to go about doing this? The data will never need to change. Example: Blob | A | B ---------------- Blob 1 | 23 | 42 Blob 2 | 34 | 21 I

Based on here on XML Attributes section I specify following in my dimens.xml : <dimen name="match_parent">-1dp</dimen> <dimen name="main_left_menu_user_account_width">@dimen/match_parent</dimen> <dimen name="main_left_menu_user_account_height">@dimen/match_parent</dimen> Then I use the both dimensions in my layout: <ImageView android:id="@+id/userAccountImage" android:background="@drawable/user_account" android:layout_width="@dimen/main_left_menu_user_account_width" android:layout_height="@dimen/main_left_menu_user_account_height" /> Then, when I preview to Graphical Layout , it complains: You
