Android :: How To Change TextView TextColor When Parent Is Focused
Oct 17, 2009I have a TextView inside a LinearLayout. The LinearLayout is able to receive focus, and I want the textColor of the TextView to change when it does. I thought using a ColorStateList would work, but it would seem that the TextView does not receive focus when the LinearLayout does. I know that, because I have tried this code...
And nothing gets logged. I don't want to use an OnFocusChangeListener on the LinearLayout to change the textColor of the TextView, I think this has to be done from XML. The reason for that is because in another activity I have an ExpandableListView with a custom adapter and custom views and Android changes the textColors of the TextViews (from light to dark) inside my custom views when items are focused.

Android :: Does The Dalvik File Format - .dx - Support More Instructions Than Java .class File
Apr 17, 2010Is there anything the Dalvik VM supports (in terms of bytecode) which is not used currently because the .class files don't have it?
As an example, if people would write their own Source-to-DX converter for their functional language XYZ, would they be able to implement e. g. full tail calls although the .class file does support tail calls only under certain circumstances?

View 8 Replies View RelatedAndroid :: SetContentView : Unable To Set TextView From Xml File / Fix It?
Sep 26, 2009I see a strange problem when I try to set a TextView, instead of a layout file via setContentView.
Case 1: i.e. if I do the following, it works fine...
TextView tv = new TextView(this); tv.setText("Hello World"); setContentView(tv);
Everything is OK.
Case 2: But suppose I have a main.xml file with a TextView in it and I try the following:
=========== View tv = findViewById(R.id.textview); setContentView(tv); =========== I get a Force Close with the below error
09-27 00:08:26.620: ERROR/AndroidRuntime(1595): Caused by: android.content.res.Resources$NotFoundException: Resource ID #0x7f050001 type #0x12 is not valid 09-27 00:08:26.620: ERROR/AndroidRuntime(1595): at android.content.res.Resources.loadXmlResourceParser(Resources.java: 1801) 09-27 00:08:26.620: ERROR/AndroidRuntime(1595): at android.content.res.Resources.getLayout(Resources.java:685) 09-27 00:08:26.620: ERROR/AndroidRuntime(1595): at android.view.LayoutInflater.inflate(LayoutInflater.java:318) 09-27 00:08:26.620: ERROR/AndroidRuntime(1595): at android.view.LayoutInflater.inflate(LayoutInflater.java:276) 09-27 00:08:26.620: ERROR/AndroidRuntime(1595): at com.android.myhelloworld.SimpleActivity.onCreate(SimpleActivity.java: 22)

Am I missing something here ?

Android :: Eclipse Class File Metadata
Jun 7, 2010In Visual Studio, I can obtain a succinct list of public methods/members exposed in a class for which I do not have the source (i.e. bundled inside a DLL) by pressing F12 (GoToDefinition).
Similarly, I am learning the Android API - in Eclipse. Jumping to an Android framework method definition produces decompilation output which is not intuitive to read, and is very verbose. To mimic results like Visual Studio, I am considering several options:
How can I format the decompilation output to be 'cleaner' - I have looked through Eclipse's preferences menus and have not found a way to do this.
How do I 'add corresponding source files' once Google provides it, so that jumping to definition yields the actual definition?
Is there a plugin that does this already? I looked into Jadclipse, but that project has not been updated in several years, and is still a decompiler.

View 1 Replies View RelatedAndroid :: Setup Background Of A TextView Dynamically From Xml File?
Oct 10, 2010I have an XMl file like below which I will use to set background for Textview:
row.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
The above Xml I will set as background for TextView in main.xml as below:
main.xml
<TextView
android:id="@+id/rowtext3"
android:text="Availablity"
android:layout_height="25px"
android:layout_width="60px"
android:textSize="10px"
android:textStyle="bold"
android:textColor="@color/black"
android:gravity="center"
android:background="@drawable/row"/>
But I want this to do from code rather than Xml.I have done everything that I have done in Xml like font,width,Height,font dynamically through code , but not able to set Background that I mentioned in Xml file . How can we set content of Xml file as background to textview similar to how we set background as XML in main.xml.
In the code I have done like this:
t1=new TextView(this);
t1.setText(ed1.getText());
t1.setHeight(25);
t1.setWidth(60);
t1.setTextSize(10);
But I didn't find how to set background i.e. how to set XML content as background?
Android :: Multiple Versions Of Same Class File For Different SDK Targets?
Nov 5, 2009This is for an Android application but I'm broadening the question to Java as I don't know how this is usually implemented. Assuming you have a project that targets a specific SDK version. A new release of the SDK is backward incompatible and requires changing three lines in one class. How is this managed in Java without duplicating any code(or by duplicating the least amount)?
I don't want to create two projects for only 3 lines that are different. What I'm trying to achieve in the end is a single executable that'll work for both versions. In C/C++, you'd have a #define based on the version. How do I achieve the same thing in Java?
