Android : Way To Specify Text Color Selector For Click Event?
Jul 22, 2010
I specified a selector drawable for the background of a layout as below, so when user clicks on the layout, the layout will have a different background. But, I didn't specify color selector for the TextViews in the layout, because there are many TextViews with different colors and I am too lazy to define color selector for them. So the text color keeps the same when the layout is clicked. My questions is, is there an automatic way to specify that the text color is highlighted/changed when the layout is clicked, so I don't have to define color selector for each of the TextViews in a layout?

I have a large text view that I am styling with a SpannableStringBuilder. I want to be able to assign custom click event handlers to certain spans of text. For example, if I click a superscript character I want it to pop up a toast with some information about what the superscript references. So far I have found linkify which helps to make regular expression type of things like emails and phone numbers launch appropriate activities. What I want to be able to do is define a span and its styling and assign a click handler to it. I haven't found anything built in that supports this kind of functionality and so I'm asking for anyone with a fresh idea of how to do this.

I have 2 questions regarding a ListView in Android:
How can I get the color of the listview's focused row ? I tried to use the ListView.getSelector() method, which according to its documentation should give me what I'm looking for, but it's giving me a Drawable object which I don't know how to retrieve the color from (if possible...).
How can I set the color of the listview's focused row ? Here I tried to use the setSelector() method on the listview, passing it a ColorDrawable object, but the result of doing it is that the whole background of the list view is painted in that color... and this is not what I wanted of course...

I'm attempting to change the background color of an Android TextView widget when the user touches it. I've created a selector for that purpose, which is stored in res/color/selector.xml and roughly looks like that:
CODE:................
The clickable attribute of the TextView is "true", in case that's of interest.
When I assign this selector to a TextView as android:background="@color/selector",
I'm getting the following exception at runtime: ERROR/AndroidRuntime(13130): Caused by: org.xmlpull.v1.XmlPullParserException: Binary XML file line #6: <item> tag requires a 'drawable' attribute or child tag defining a drawable
When I change the attribute to drawable, it works, but the result is looking completely wrong because the IDs appear to be interpreted as image references instead of color references (as the "drawable" suggests).
What confuses me is that I can set a color reference, e.g. "@color/black", as the background attribute directly. This is working as expected. Using selectors doesn't work.
I can also use the selector as the textColor without problems.
What's the correct way to apply a background-color-selector to a TextView in Android?

I'm trying to use a color defined in a stlyle in a selector but it is causing a Resources$NotFoundException.
First I added a new attribute to attr.xml:
CODE:..........
Then I defined that attr value in styles.xml:
CODE:..........
Then I tried to use that attr in my selector definition:
CODE:................
Lastly, the activity uses the ThemeNoTitleBar style theme in the manifest.
I've also tried creating a color in colors.xml and having it use the new attr but that also fails.
I'm obviously missing something but am not sure what to do to fix it. My intent is to create multiple themes and have the selector use the color in the currently selected theme.

The layout xml is as below. I have a RelativeLayout, which contains a TextView. The OnClick listener is set on RelativeLayout. The RelativeLayout has a selector background. What I want is, when user clicks on the RelativeLayout, the background of the RelativeLayout should change, and the color of the text of the TextView should change too. Even though I set color selector for the TextView, only the selector on RelativeLayout works. The color selector on TextView doesn't work. How can I implement change of both RelativeLayout background and text color of TextView when user clicks the layout?

I am new to Android development and I am currently working through a tutorial but have already run into a brick wall. I am trying to handle a simple button click following some sample code but can't get it to work. I do not get any errors, but the click does not register on the emulator.

I'm trying automate UI Functional testing of my application.
1) First phase: Record the user actions and playing back the same.
2) Second Phase: Adding Validation Capability to Recorded scripts.
In First Phase: I'm able to automate the Text/Editbox control actions without any issues, because we need to Set the Text of the control to the recorded value, so, its simple. While coming to Button Control actions, we need to simulate user actons, like Clicking on button. Can anyone suggest me, Do we have any mechanism, which can simulate button click event in Android?

Here is my problem : I have a view containing a listView. And each row of this listview is composed of a linearLayout, itself composed of three textview and a gridView. Here is a summary of my layout for one row:
......
I want to perform an action when the user click anywere on an item of the listview. So I try these two approaches on the listview : - myActivity.getListView().setOnTouchListener(new View.OnTouchListener () {...}) - myActivity.getListView().setOnItemClickListener(new AdapterView.OnItemClickListener() { ...}) And here is the trouble : - when I click on the textview, it nearly works : the touch listener is called, but not the clicklistener - when I click on the gridView it doesn't work....the event is just dispatched to the element of the gridView.............

I displayed map and on top of map, I displayed a number of overlay Items(Markers). Clicking on overlay Items or markers will do some action. But the problem is when I click around the marker, means outside the marker, at that time also, the event triggers. I want to restrict that exactly when I am clicking on the marker, event has to take place. I am doing the event in opTap() method.
How can I restrict the event triggering to exactly when I click on the marker.

I have button, which displays a Context menu. In the menu are few items (some of them are disabled - setEnabled(false)).
Which event is called when a user click on the disabled item? It's not onContextItemSelected nor onContextMenuClosed. But the menu is closed after the click.
