I want to do something like that. For example, I have a textview with String
Alibaba love Mary so muck. In that String alibaba and Mary have a event to open something but I can't know how to use event for Mary and Alibaba seperately
Maybe it is a simple problem for some of you. But how do you automatically cut off long strings and add "..." to the right end in TextViews, like Activity title does? Sorry for posting twice coz I didn't see my previous post in the list

TextView control to my app. by default, its set to something like @+id/TextView01. How do I Set the text attribute of the TextView control to my newly created String resource? I tried going into main.xml and just editing the android:text to point to the name of my new string, but it didn't seem to work.
I think the answer to this question is probably so simple, but I'm struggling....
I have a TableLayout with multiple columns. I want the last column to be of a fixed width, but I want to define that width to just be able to hold the widest possible string from my program. i.e. it is always wide enough to contain "THIS STRING" without wrapping, or wasting any space.
I would like to do this as I have these TableLayouts within a ListView, so it looks very poor when the last column is of variable widths.
I have tried obtaining the string width, even going so far as to put it into a TextView, call getTextSize() then setWidth() on all appropriate TextViews. The problem I hit there is that gettextSize() returns pixels, but setWidth uses ScaledPixels.
I'm sure there is a really simple solution. Can anyone help?
If a String is longer than the TextView's width it automatically wraps onto the next line. I can avoid this by using android:singleLine (deprecated) or by setting android:inputType="text". What I now need is something that replaces the last 3 characters of my String with "...". Since I'm not using a monospace font this will always be different depending on the letters used in my String. So I'm wondering what's the best way to get the last 3 characters of a String in a TextView and replace them. Maybe there's already something implemented in the Android framework, since this must me a common problem.
View 2 Replies View RelatedOn Android 1.5, using the Allocation Tracker I see that every time I call TextView.setText() with a StringBuilder as first argument, a String gets allocated from the following call stack (first line is last call):
java.lang.AbstractStringBuilder toString java.lang.StringBuilder toString android.text.TextUtils stringOrSpannedString android.widget.TextView setText
I tried specifying the buffer type with setText(strBuilder, TextView.BufferType.NORMAL) but it doesn't change anything.
Is there a way to avoid this allocation?
I have an object on my main.xml layout file called thefact that is TextView. I also have a string called sharefact. I want to save what text is in the TextView into the sharefact string. I can't do:
sharefact = thefact
Or anything similar to that because it would want me to convert sharefact into a textview.
i'm working on an android application with 2 activities.
The first activity contains 2 buttons ( btn1 , btn2).
The second activity contains a textview and a back button.
In the string.xml I have two strings ( str1, str2).
What I want is when I click on btn1 the second activity should open and the textview will show the first string str1 and when I click on the second button btn2 the second activity open and the same textview show the second string str2.
I want to make a textView1 that displays my random generated number when clicked on button1. so that i can build 5 questions with the if element. the main question is how do i get my random generated number in a textView?
I know there is a big chance the random number gen won't work but I am new in the Android scripting and want to discover new things, how to get a random number gen. but don't put to much effort.
Code:
package EasyApp.randomquestion;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.TextView;
import android.widget.Button;
[Code] .....
Here are some HTML ASCII Codes:

I am trying to make an android widget like the Google Voice Widget where users can go through an array of Strings which is retreived from the SQLite database. The problem is using global variables in the widget provider. I need to hold the index of the value they are currently on in order to pass it to the intents which are created when the left or right buttons are created. The variable is always returned as zero though.

How can I pass a string from an activity to a layout?
I can pass arrays from an activity to a layout with the following activity code...
Is there a simpler way to just pass a single string instead of any array of strings, from an activity to a layout?
Brand new to droid programming, but would love to learn as much as possible, so I finally got my emulator working correctly, I even got a hello world button to work. I'm attempting to make this button display a random number, I've googled this and came up with this code:
Random generator = new Random();
int n = generator.nextInt(n);
I fixed the Random function by including some Random java utility. I'm assuming this code above goes in the .java file of the project, so my button code looks as follows (tested and works):
PopUpText.makeText(v.getContext(), "Hello World",
PopUpText.LENGTH_LONG).show();
I figured I could replace "Hello World" with n to display the number in the box, however the following error is stopping the compile:
The local variable n may not have been initialized
Ok, im fairly new to android but i have managed to teach myself the basics, i am making an app where you press a button , and a new screen opens and it shows a randomly generated number, the only problem is i dont know how to generate and display the random number, i have been searching the web for ages and have only found little snippets of information , that dosent really make sense to me.

I want to have a textview (like a console or output window), which scrolls. I saw on this list that the TextView will not scroll on its own unless I wrap it in a ScrollView. So I did that and it worked. The problem is, it seemed no matter what I did I could not get the TextView to be higher than one line. This was only when it was embedded in the ScrollView, and didn't seem to change whatever I set the TexView's layout_height to.
Here is my layout:

View 4 Replies View RelatedI have an app that uses a TabHost. Several of the Tabs share a common HUD. I am using a service to periodically update those values by calling an AIDL function when ready.
However, since several of the Tabs are using the same HUD I would like to abstract that part out.
I thought about having the HUD.xml use a String resource as it's value and then the abstracted class can update the String resource. However, apparently Android can not update String resources programatically.
The only alternative solution I see would be using SharedPreference.
I have concerns accessing a Database everytime the value is refreshed.

When a marker is clicked on google map, a small square area is displayed with hyperlinks. I guess OverlayItem does not render hyperlinks for its snippet. How to achieve this? Ideally I want to assign a layout with all sorts widgets. Presume I can display a small floating activity window when the marker is clicked, but is this the standard way doing this? The drawback of floating activity window is that if want to click another marker, user has to dismiss the current window first.
