I have a TextView with an OnTouchListener. What I want is the character index the user is pointing to when I get the MotionEvent. Is there any way to get to the underlying font metrics of the TextView?

I am using a ListView with an ArrayAdapter that holds objects. When I select an item, I am capturing the position and index of the selected item. If I scroll down prior to selection, the position and index represent the location of the item in the list. Selecting that items takes me to another activity. When I use the back button to return to the list, it seems that the ListView gets a new position and index for the visible items.
As a result, I can't figure out how to reference the selected item during the restart() of the ListView Activity. I have tried to capture position and index, but as I've said, they change upon returning to the Activity.
Is my understanding of the ListView "redraw" correct? Does it renumber my items based on what's visible? -When in the life cycle is getView() called? Is there a way to force an update to the ListView so that my captured index still points to the same object?
I am creating a list .. the elements of the list are drawn from sqlite database .. I populate the list using ArrayList and ArrayAdapter ...upon clicking the items on the list I want to be able to fire an intent containing info about the item clicked ... info like the index number of the item .. using the method : onItemClick(AdapterView av, View v, int index, long arg)
I do get index of the item clicked . however it is of the list currently displayed . the problem comes when I do setFilterTextEnabled(true) , and on the app type in some text to to search some item ..and then click it ..rather than giving me the index of the item on the original list it gives me the index on filtered list..
following is the snippet of code:
myListView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> av, View v, int index, long arg) {
Intent lyricsViewIntent = new Intent(iginga.this, LyricsPage.class);
lyricsViewIntent.putExtra("title", songList.get((int)arg).getTitle());
lyricsViewIntent.putExtra("id", songList.get((int)arg).getSongId());
startActivity(lyricsViewIntent);
}
});
myListView.setTextFilterEnabled(true);
Is there any way I can get the original index /position of the item instead of the one showing in filtered text ...when filtered.
I have created a textview with the below code:
CODE:.........
As above, i have set the 5 Lines as maximum for the textview.
But my doubt is: if the string which i am going to display in Textview if it exceeds 5 lines, then it will be fitted upto 5 lines ending with "..." characters.
e.g.
Hello this is the demo of
string which i have
created especially for
the demo of textview
and setting maximum...
As same as above, i want to display in TextView output.
I'm tring to create SMTP-POP3 mailer application on Android. Then I came across a problem when I display e-mail written in Japanease.

Are there any way which I should do to display Japanese on TextView?
I have an application that shows a textview occupying most of the screen. When the user clicks on a portion of the textview I want to find the closest character to where they clicked so I can show them information about that part of the text in detail. I have the OnTouchListener and I can get the x,y of the click but does anyone have any idea how I can use that to get the closest character in the textview?

View 2 Replies View RelatedI have a layout that looks something like this:
[TextView 1] [TextView 2]
[ TextView 2 spill-over ]
Essentially, I need the contents of TextView 2 to wrap to the next line, but start where TextView 1 starts. I was thinking that if I knew how much text would fit into TextView 2 before it runs out of space on line one, I could take the rest of the text and put it in another TextView below the first two. So I need to measure how much text will fit into a TextView (which can be tricky because as far as I can tell, Android will try to break the text in a TextView at a good location so that it won't break a word in the middle if it can be avoided) or I need a new idea on how to lay this out.
How can I determine the number of visible characters that a TextView can display. For example if I change the orientation this number may change. If I change the resolution then also the number of visible characters changes.

View 3 Replies View RelatedI simply populate the database from a text file where each line is a new entry into the table so a line would look like this "This is on first line.This is on second line" and it is stored as text.Is there a reason that it isn't displaying the characters properly? It must be something to do with the string being in the database.
View 3 Replies View RelatedI'm trying to make a ScrollView with a list of numbers in it that the user can select from. After the user touches and scrolls, after the finger is lifted I want the scroll to "snap" to the item in the middle of the ScrollView and give me the output. My ScrollView contains a vertical linear layout with TextView objects in it. The ScrollView's vertical size is about 60sp.
I think this would involve the ScrollView.onTouch with a ACTION_UP, but I don't know how to use it. Also, is there a way to get an item's index or value based on a position in the list?

When mouse clicks, OnTouchEvent() of some view will still be called. What I want is only to disable Touch event because my application need not Touch and Touch event will disturb the running of app. Is there any way to disable Touch ?

View 2 Replies View RelatedI need to make a service that capture all touch events, not in a specific view or when an specific activity is open. This service is started when the boot is completed (and I have an app to stop/play this service when I want it). So it write something (in a Toast) when the user touch any place in the screen.
Can I do this? Or only in specifics things (with OnTouchListener and adding specifics views, for example)?

View 3 Replies View RelatedI'm new to Android, I've followed the hello world tutorial through and have a basic idea of what's going on. I'm particularly interested in the touch screen of my T-Mobile Pulse so just to get me started I want to be able to write the co-ordinates of a tocuh event on the screen, so say the user touched the co-ordinate 5,2 - a textview on the screen would display that.
At present I have a simple program that just loads an xml file which contains the textview I intend to write the co-ordinates in.
Thank you in advance, I did Google for help and searched stackoverflow but everything I found either went way over my head or wasn't suitable for this.
I need your help in differentiate between touch event and drag. since I need to do action when user touch the screen and another action when it touch and drag. I wrote the code below but it only works for touch but not for drag. ret is the return value of the onTouch method. Code...
View 4 Replies View RelatedHere 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 have created a list activity where i have placed some items and i am using OnListItemClick to get the desired actions through D-pad and KeyLeft and KeyRight Buttons, In Emulator TouchEvent is not working , I want to know whether it works in real Handsets?

View 2 Replies View RelatedI'd like to receive a TouchEvent in my Android application any time the screen is touched. Even if my application is not in focus.Is there an general even listener or intent filter I can write to achieve this? The goal is to write system wide gesture engine. So for example, if the user swiped up and then down, a certain application would be launched regardless of where the user is.
View 2 Replies View RelatedI'm working on a simple game: when you press a button on the screen, a character will run to certain direction. It's easy to support keyboard input. But, some phone doesn't go with a keyboard or even no a track ball. So I decided to draw a virtual "run" key on the screen (with opengl). When the user press the virtual key, I apply a velocity to the character. And when the user release the key, I disable the velocity to stop the character but there seems to be some touch event noisy. If my finger cannot press still, I will see millions of touch down and touch up events, instead of a single long pressing.
And occasionally, my program captured the touch down event when I touch the screen, but didn't capture touch up event. So my character will keep moving, even no finger is on the screen. I'm wondering if there is some way to reduce the touch event noisy and tell if the user is currently pressing on the screen, instead of only getting an event when touch up and down happen. It seems the system UI can detect long pressing, for example when you put a finger on one item of the list view widget, the entire item turns to orange. I just don't know how to detect pressing in my opengl game.
I like to know using which version of Android SDK we can develop multi touch handling. Does Android SDK 1.6 support multi touch? If yes, can i get some sample code, where i can have multiple imagebuttons placed on screen and clicking on all the imagebuttons at a time should detect multiple touch events?
