Android :: Create Text View That Flashes When Clicked
Apr 2, 2010
How do I set up a TextView to flash when it is clicked? With flashing I mean that I want to change the background color of the TextView. I essentially want one of the objects that is displayed in a ListActivity, but inside a normal View. I have tried to do this by adding an OnClickListener, but what I really need is something like adding an On(Un)SelectListener. Using the onClickListener, I can change the TextView background, but obviously the background stays that color. I thought of using a new Handler().postDelayed(new Runnable(){... }) kind of thing to reset the backround after some small time, but I did not know if this would be overkill for what I'm trying to do.What would you recommend?

I am trying to set the Text of a Text View when a button is clicked.
I have been struggling, because the variable will increment, but If i put the code in to set the text, it crashes the app ?
Here is my code when it crashes:
Quote:
package com.example.test;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
[Code].....
however if I comment out the line
Quote:
score.setText(points);
, the app doesnt crash, but it doesnt do anything then.

s8="hello";
t12=(TextView) findViewById(R.id.solid);
t12.setText("check"+"/n"+s8);

I am trying to implement a drop down list when a button is clicked.
So, I have a text view and a button in a navigation bar(nav.xml) and a corresponding list view. This navigation bar is included in another page( products.xml)
when the button is clicked i get the list view right below the button(which is what i want to achieve) but its my moving all the contents on the current page downwards, even the text view which is placed in nav bar moved downwards.
I am totally new to Android, any sample examples or a way how to achieve it?

I have a problem with my DDMS in eclipse. In the logcat view appears only this failure: Logcat View fails with "Could not create the view: For input string: "our" "
I uninstalled and reinstalled the adt and ddms already without any change. I can use the logcat in the command line (tools- adt logcat) but this is not as comfortable as using the logcat in eclipse.
More details of this failure message are:

I have a selection for some items using a spinner widget. At the moment the spinner will load a simple Textview and show the name of the item.It is possible to define an own view to show inside the spinner row? I would suspect it being similar to a custom List row.I simply want to show an individual icon left from the spinner text for each item in the list.

I've tried to add a TextView before a ListView in a LinearLayout. The result is that the ListView wont show at all. The same thing happens if I put the TextView after the ListView, but then I will only see the ListView. Is there a way to get a text view above the ListView without to much of a hassle?

Specifically, I'm curious about how they did the phone number entry part, where they can add additional phone numbers fields when the user clicks the little add button. I initially thought that was done with a ListView, and I got a ListView to work, but the ListView scrolls independently of the rest of the screen, which looks bad.
So I was wondering what the best approach for something like that is? Am I on the right track with the ListView and just missing something allowing me keep it from behaving like it's own scrollable container? Perhaps a custom AdapterView or maybe just with a TableLayout dynamically adding rows? I'm just not sure what would work the best.

I am on Android 2.1 and I have one multi column Custom listview Using BaseAdapter with an editable edittext at the end of the listview. If the data in the listview do not contain the data of user choice then user should be able to enter data. If the data is already there in the list user will be able to select the data using custom selector. If a selection is made in the list view and user wanted to enter data in the text field at the bottom after selection then the marker in the list view should be unselected. I tried to use onclick() method on edit text using click listener. First time when it is clicked, edit text is getting focus and onclick() method is not fired. And when it is clicked second time, onclick() method is fired and notifyDataSetChanged() method is called. I tried to call the notifyDataSetChanged() method from the Focus Listener, list view selection is gone in my first attempt and edit text is not receiving any data input from the keyboard (frozen).

I'm just wondering if I'm able to create a View from an external XML source. As I was reading, you must place the XML layout inside the res/layout and when you compile it, you can load the layout by typing setContentView(R.layouts.my_layout). What if I have this XML layout online (on a website) and I want to create the layout on runtime? Is there any way to do this? Or I have to parse the XML and create the layout (hard-coded)?

I'm stuck on a problem and if possible I will need help from the community. I'm not looking for a ready-made solution, but something which would help me to produce the result.
I'm looking for a way to produce a dynamic activity based on a JSONArray object.
Here an example of a JSONArray object:
[ { "name": "my checkbox name",
"type": "checkbox",
"value": "one,two,three"
}
{ "name": "my edit text",
"type": "text",
"value": ""}...]
This JSONArray could be totally random. It could have 2 text views, 3 select menus, 1 text view and so on.
The goal is to iterate over this JSONArray and create the appropriate elements within my android code.
To produce the result I've thought of a simple switch which would render one by one my different JSONArray to an android widget.
But after that how could I have access of every property of every widget rendered?
Edit: I need as well to assign an event listener on some widget as taking the GPS coordinated...
