Android :: How To Display An Array And Edittext Box On Same Screen

Oct 18, 2010

In most tutorials is how to display only one of them, I noticed to display an array, main class should use interface from ListActivity, but when i try display something else (like my edittext box) program crashes.

Somebody suggest me To display an array like that:

ArrayAdapter<String> myAdaptor = new ArrayAdapter<String>(this,R.layout.test,myStrings); myListView.setAdapter(myAdaptor);

but this is not doing anything.

Can anyone tell Me what is wrong in this lines or explain me how to solve my problem?

Jul 28, 2010

I have a ListView activity and I want an EditText (and ultimately a button along with it) to display above it.

I believe my xml is fine, but for some reason the EditText is not displaying. The ListView takes up the entire screen :(

Here's what my XML looks like:

In the layout tab of the xml file in Eclipse, the EditText shows. When I run my application in the emulator, it does not.

Here is where I set the content view in my onCreate method

Android :: Converting Byte Rgb_565 Array Into Argb Or Rgb Array

Jan 12, 2010

I have Picture data in byte rgb_565 array, and I want convert it in a productive way into argb array. Right now I have found only one (little slow) way to do this: Bitmap mPhotoPicture = BitmapFactory.decodeByteArray(imageData, 0 , imageData.length);

where imageData is my byte[] array in rgb_565, and then: int pixels[] = new int[CameraView.PICTURE_HEIGHT*CameraView.PICTURE_WIDTH]; mPhotoPicture.getPixels(pixels, 0,PICTURE_WIDTH, 0, 0, PICTURE_WIDTH, PICTURE_HEIGHT);

The point is I believe creating a Bitmap object is exacting and not necessary in this case. Is there any other faster way to convert rgb_565 array into argb array? I need this because making image processing on rgb_565 array seems to be a little annoying. Or maybe it is not so hard?

Android :: Converting Short Array To Byte Array

Feb 16, 2010

I am trying to make an application that would be able to send the user's voice over the network using RTP. I am using the ported stack from hsc (JLIBRTP) and I am able to record user's voice in a saperate thread. the problem is that jlibrtp uses has a class named RTPSession that is responsible for the session and has the sendData method that takes a byte [] as argument and the AudioFormat class I am using to record user's voice is in AudioFormat.ENCODING_PCM_16BIT wich is short. I have tried using 8bit audioformat but I get an illigalargument exception in my htc magic and in my emulator. So is there any way I can convert the short [] to byte [] ? would that be acceptable in order of voice quality?, is the above error a known bug for htc magic or the platform doesn't support 8bit audio format?

Android :: Navigating An Array - String Array

Oct 12, 2010

I'm new to android developing but right now I'm working on an application that displays Random Facts. Since I don't want it to be in a random order, I would like to have them in a list. I would like to order through them one by one and show them using TextView.

Resources res = getResources();
myString = res.getStringArray(R.array.FactsArray);

That's what I have so far. If I'm right, that just establishes the array so I can be able to use it later. What I had before was rgenerator which chose a random string from the array and displayed it when I clicked a button.

CODE:................

But Like I said, I would like to just order through them one by one when a button is clicked.

Android :: Using Edittext - Create A Login Screen

Jun 21, 2010

I've got a few questions about edittext..

I'm trying to create a login screen on Android. I'm taking in a username and a password and then sending the results to another method. I've just got a few questions about it...

1) If I have two edittext's and the user enters values in both and then hits a "login" button, I want the button to take the values that were entered in the 2 edittext boxes, convert and save them to a string and then pass them to a function. I'm unsure how I'd construct this button. The problem I'm having is making it a string I'm currently doing this.. String user = edittext.getText();

But that doesn't seem to work. Also I'm unsure what way Android saves Edittext inputs.. Will it just automatically save it to the string once the user is no longer working out of the box? e.g will...

CODE:........

work? If not how would I define it?

Android :: To Make EditText Look Like TextView But Still Behave Like EditText

May 17, 2009

I want an EditText to look like TextView but still behave like EditText. I've tried applying TextView style to my EditText in my layout.xml file, like this:

CODE:............

But I get an error within xml editor: "Error: No resource found that matches the given name (at 'style' with value '@android:style/ Widget_TextView')." It is strange because @android:style/ Widget_TextView definitively exists - I double checked it in code via android.R.style.Widget_TextView. Another strange thing is that I don't get android:style offered in the xml editor while typing? There is android:id, android:text and everything else.. but not android:style?

I consider the hard way (making EditText look like TextView) to be: extending EditText and overriding it's onDraw method.

Android :: Blank Screen Appear When EditText Get Focus In IDPI Mode

Oct 10, 2010

I found that when EditText in placing at the bottom of screen, and the activity's android:windowSoftInputMode="adjustPan", and the apps run in ldpi(240*320) mode, then when EditText has focus, the content of the activity is panned too far to the above, thus leaving a blank screen between the content of the window and the soft input panel.

You can see the screenshot of this problem at
https://sites.google.com/site/wilderwang/android
Also, the source code to repro this problem can also be get at
https://sites.google.com/site/wilderwang/android

When I test further, if the same apps run in hdpi(480*800), when EditText got focus, the content of the window panned too small thus causing the soft input window cover the EditText view. It seems the distance of the window panned not compute the screen density.

Android :: Layout - Screen Wont Move Up To Allow Input In EditText At The Bottom

Jul 29, 2010

Hopefully this is just something easy since I'm still wet behind the ears with programming for android. My issue is that i have a couple EditText boxes at the bottom of my layout. When in the emulator they work as expected, you touch the edittext and the screen scrolls up so you can see the content. However when i try it on my droid inc the edittext is covered by the keyboard.

Android : EditText Items In A Scrolling List Lose Their Changes When Scrolled Off Screen

Jun 14, 2010

I have a long scrolling list of EditText items created by a SimpleCursorAdapter and prepopulated with values from an SQLite database. I make this by: cursor = db.rawQuery("SELECT _id, criterion, localweight, globalweight FROM " + dbTableName + " ORDER BY criterion", null); startManagingCursor(cursor); mAdapter = new SimpleCursorAdapter(this, R.layout.weight_edit_items, cursor, new String[]{"criterion","localweight","globalweight"}, new int[]{R.id.criterion_edit, R.id.localweight_edit, R.id.globalweight_edit}); is.setListAdapter(mAdapter); The scrolling list is several emulator screens long. The items display OK - scrolling through them shows that each has the correct value from the database. I can make an edit change to any of the EditTexts and the new text is accepted and displayed in the box. if I then scroll the list far enough to take the edited item off the screen, when I scroll back to look at it again its value has returned to what it was before I made the changes, ie. my edits have been lost. In trying to sort this out, I've done a getText to look at what's in the EditText after I've done my edits (and before a scroll) and getText returns the original text, even though the EditText is displaying my new text. It seems that the EditText has only accepted my edits superficially and they haven't been bound to the EditText, meaning they get dropped when scrolled off the screen. Can anyone please tell me what's going on here and what I need to do to force the EditText to retain its edits?

Android :: ScrollView With EditText - Scrolling In EditText

May 14, 2010

Our app (WordPress for Android) uses a ScrollView for the new blog post view. The issue is that if a user writes a lengthy blog post in the EditText, they are unable to scroll inside of the EditText because the ScrollView seems to be taking over the scrolling action, even when you are in the EditText.

Here's the layout XML (the EditText in question is @id/content):

Android :: Placing A TextView Before EditText Element In Android Layout XML Causes EditText Not To Show

Jul 29, 2010

Every time I put a TextView before an EditText element in a LinearLayout, the EditText does not show. When I don't, it does.

I've narrowed the problem down to the TextView's layout_width attribute. If I give it "wrap_content", it works, but doesn't "block" down, and it appears on the same line as the EditText.

Android :: Android Home Screen Widget Failing With EditText / Get It To Work?

May 26, 2010

Whenever I add an EditText widget to the layout of my home screen widget (confusing how the term "widget" is being used twice in the Android lexicon :-/ ), I receive the "Problem Loading Widget" error box.

Here is the layout I'm attempting; if you remove the EditText, it works.... code...

Now, the Google Search home screen widget has an EditText, so it's obviously legal to implement. Any thoughts on why this is not working?

Android :: Android - EditText And Button - When Click Button - Unfocus EditText And Hide Soft Keyboard

Jun 24, 2010

CODE:............

I have this at the top of my application. When the application starts, the EditText is orange highlighted and has a cursor in it; when the EditText is tapped, the soft keyboard pops up. The user uses it to type into the EditText.

However, when they click the Button, my onClick method fires and does everything it's supposed to, however the soft keyboard stays on screen and the EditText is still highlighted with its cursor.

I also have, at the top of the Button onclick: findViewById(R.id.name).clearFocus();

In spite of this, the EditText does not seem to clear its focus. How do I make the button actually act as if it is submitting the form?

Also, I do not transition to a different Activity on the click of the Button. I suppose that is the typical case, and probably the reason why they don't bother hiding the keyboard. However I want to keep the search box and button at the top of the screen, so I just dynamically fill and add views to the screen when the Button is pressed. How can I achieve my desired behavior?

The app in question is a database driven app and I would love to include some 3 - 4 screens to help the user create re-usable resources for use within the app and a few tips. They would be Dialog Alerts with the last welcome screen showing the "Do Not Show Again" checkbox. how to show the welcome screen just once.

Android :: How To Switch On / Off Screen Display?

Oct 23, 2009

I have a requirement to turn the screen display on and off from a Android Service. I should have a function SwitchScreenDisplay (ON/OFF), to ON or OFF the display. I searched through the SDK and found a few APIs and settings. One method I found is
boolean err = android.provider.Settings.Secure.putInt(myThis.getContentResolver(), Settings.System.SCREEN_OFF_TIMEOUT, 1);

But it gave the following security permission exception
[03-14 21:24:41.575: ERROR/DatabaseUtils(1066): java.lang.SecurityException: Permission denial: writing to secure settings requires android.permission.WRITE_SECURE_SETTINGS] even though I had added the following statement in
AndroidMenifestFile.xml <uses-permission android:name = "android.permission.WRITE_SECURE_SETTINGS"></uses-permission>

So my question is: Was the above method is the right way to SWITCH OFF the screen - How does the Long End Key press, switches/powers off the display? Which API it calls? - How to Switch on? Is it using the PowerManager wakelock?
