Android :: Using Text Field With AdapterView
Jun 2, 2010
Is it possible to use AdapterView with text fields in android?
My query returns a set of values and for each I want to place that within a textfield, so that the user may edit the value.
Also, I want to click a button to create a new empty field, so that I may insert a new entry.
If you know of good example, then please let me know!
I would prefer to use XML to define ui and I found this informations:
"In this case we create a new id called text1. The + after the @ in the id string indicates that the id should be automatically created as a resource if it does not already exist, so we are defining text1 on the fly and then using it." Source http://developer.android.com/resources/tutorials/notepad/notepad-ex1.html
Will this + allow me to autocreate as many fields as needed? Is there a way I can generically specify the layout in XML and then create fields adhoc based on db response?

I want to open soft keyboard while starting an activity. The activity contains nothing as its element. I just need to open soft keyboard on the launch. I've tried with
<activity android:windowSoftInputMode="stateAlwaysVisible|stateVisible|adjustResize" but it didn't work.
Also tried with
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
but it didn't work as well i'm using emulator to run the code

If I have an EditText component on my screen that I have specified inputType="decimal" for (i.e. a numeric/decimal field), what is the best way to convert it to an decimal value in the application code?
Google recommends avoiding floats, and avoiding creating objects unnecessarily (and I assume any auto-unboxing code is bad too), so I take these as my constraints. I realize a small application probably doesn't need to worry too much, but I haven't been able to find a 'best-practice' solution to this.
The most common solution appears to be this:
double value = Double.parseDouble(txtInput);

I'm creating a custom widget that extends AdapterView. Imagine something like a ListView except that the list items can overlap each other with some transparency. Because of the overlap, I'm trying to control the layout and drawing order of the children.
My issue is that the control renders it's children, but ONLY one level deep. Each child is inflated from an XML resource that contains a FrameLayout and an ImageView. The FrameLayout draws, but the ImageView is never visible. I assume I need to call some method to tell the FrameLayout to layout or draw it's children, but I'm not sure what, why, or where. Does anyone know what I'm missing?
Here is the relevant code for my custom widget: Code...

I have encountered a problem with focused text fields in a WebView not showing entered text values.As long as a WebView text field has focus it will not show text or even the blinking cursor.You can select and highlight the text or unfocus the field to see it, but when it gains focus it will not show the text as if the foreground color of the text is white.The simplest code to demonstrate this is below.With the setTheme using a Light background, try typing values into the Email text field to notice that the text is not visible when the field is focused.

I have a simple EditText field in one of my Activities. If I set the field to disabled, it greys out and I cannot enter text with the hardware keyboard, however when I touch the field the virtual keyboard appears and that still lets me enter text. Is this a bug? Any workarounds for making sure this can't happen?

Say you are fully zoomed out on some internet page and you see a text field....you touch the text box to type in it. Instead of allowing you to type, it zooms in on the text box. Why? And sometimes, actually most of the time, it zooms in to the wrong area and I have to scroll around to find the text box I was going to type in. So, can I turn off that particular zoom feature? Or can the zoom feature be made accurate....because most of the time it is not accurate at all and the zoom completely misses the text box.

I have noticed that when using my phone to reply to a long string of text on forums (or at least some of them) I seem to hit a roadblock at some point. By that I mean, if I wanted to reply to a message like I am typing this right now, if I want to scroll down to the bottom I am unable to if the length of the text reaches a certain point. Or in another situation, I could be typing my reply, but once I write enough to reach that limit I am unable to type any further. This only applies when wanting to reply at the bottom of the string of text. There are ways to work around the issue, but in certain cases they aren't always preferred.

I'm trying to make (for learning purposes) my own implementation of a simple AdapterView where items comes from an basic Adapter (ImageAdapter from sdk samples).
Actual code is like this:
public class MyAdapterView extends AdapterView<ImageAdapter> implements AdapterView.OnItemClickListener{
private ImageAdapter mAdapter;
public MyAdapterView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
initThings();}
private void initThings(){
setOnItemClickListener(this);}
@Overridepublic ImageAdapter getAdapter() {
// TODO Auto-generated method stubreturn mAdapter;}
@Overridepublic void setAdapter(ImageAdapter adapter) {
// TODO Auto-generated method stub
mAdapter=adapter;
requestLayout();}
View obtainView(int position) {
View child = mAdapter.getView(position, null, this);
return child;} code...
This isn't a coding masterpiece, it just displays a pseudo-listview with pictures. I know i could've used ListView, GridView, Spinner, etc. but i'm relative new to android and i'm trying to figure out some things on it. Well, the question here is Why is my onItemClick not firing?
Using the same ImageAdapter with a GridView, everything works ok, but when i use with above class, i get nothing. Inside AdapterView.java there is code for those click, longclick, etc events... so why can't i just fire them? Maybe i'm misunderstanding basic things on how AdapterView works? Should I extend other base classes instead? And why? Hoping to find more experienced guidance on here, thanks in advance.

I have been looking for something similar to the feature which is available on the Nexus one, which is the ability to enter text via speach on any text input.
I know its available for the google search on the X10, but does anybody know if its available for every text box?

I have a Samsung Galaxy S3 (4G). In the email application (standard) it seems to store all of the email addresses from emails I've received, even SPAM emails.
Now when I send an email and enter the "to" field, it suggests these email addresses. How do I clear out all of these stored suggestive email addresses from my phone? None of them are in my contacts lists.
Im using just normal pop email and the standard email app. I've tried cleaners, clearing cache, deleting email accounts - everything.

I'm writing an Android application that allows a user to maintain a list of products. In the EnterProductData activity, the user can enter information about the product into form fields, which will then save the info to a SQLite DB. The EnterProductData activity also allows the user to initiate a barcode scan via the Barcode Scanner app in order to capture the UPC code. The problem I'm facing is trying to set the value of the UPC text field in onActivityResult() once the barcode scan activity is complete and returns the value.
What is ending up happening is my onResume() method is calling a function (populateFields()) that sets the values of the text fields to whatever is currently saved in the DB. And this seems to be happening after onActivityResult() is called. This means the scanned UPC is set as the text field value, only for an empty value to be set to it immediately after. The line of code to blame is commented with asterisks next to it. I imagine that if I immediately save the scanned UPC to the DB in the onActivityResult() method, I can avoid this problem, but that doesn't seem to be the best practice, in my opinion. Can someone advise me on what I should do?
EnterProductData.java
public class EnterProductData extends Activity {
private Button mScanButton;
private EditText mUPC;
private Button mSaveButton;
private Long mRowId;
private DbAdapter mDbHelper;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mDbHelper = new DbAdapter(this);
mDbHelper.open();
setContentView(R.layout.enter_product_data);
mUPC = (EditText) findViewById(R.id.UPC);
mScanButton = (Button) findViewById(R.id.scanButton);
mSaveButton = (Button) findViewById(R.id.saveButton);
mRowId = (savedInstanceState == null) ? null :
(Long) savedInstanceState.getSerializable(DbAdapter.KEY_PRODUCT_ROWID);
if (mRowId == null) {
Bundle extras = getIntent().getExtras();
mRowId = extras != null ? extras.getLong(DbAdapter.KEY_PRODUCT_ROWID): null;}
populateFields();
mScanButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
IntentIntegrator.initiateScan(EnterProductData.this);}});
mSaveButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
setResult(RESULT_OK);
finish();}});
}private void populateFields() {
if (mRowId != null) {
Cursor product = mDbHelper.fetchProduct(mRowId);
startManagingCursor(product);
mUPC.setText(product.getString(
product.getColumnIndexOrThrow(DbAdapter.KEY_UPC))); //******}
}@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
saveState();
outState.putSerializable(DbAdapter.KEY_PRODUCT_ROWID, mRowId);
}@Override
protected void onPause() {
super.onPause();
saveState();
}@Override
protected void onResume() {
super.onResume();
populateFields();
}private void saveState() {String upc= mUPC.getText().toString();
if (mRowId == null) {
long id = mDbHelper.createProduct(mRowId, UPC);
if (id > 0) mRowId = id;
}} else {mDbHelper.updateProduct(mRowId, UPC);
}}protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch(requestCode) {
case IntentIntegrator.REQUEST_CODE: {
if (resultCode != RESULT_CANCELED) {
IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if (scanResult != null) {
String upc = scanResult.getContents();
mUPC.setText(upc);
}}break;
}}}}

I have noticed a rash of EMF "detectors" currently available for the iPhone 3GS only.
Does the Milestone/Droid series phones have the capability to detect EMF and if so does anyone know of a current app or one in development that will do this? I've searched the app store without finding a clear result.

I have an EditText field and a button. My aim is to let user enter text info to the EditText or click the button to launch a dialog to select some checkbox and radio button which it will perform some computation and return a value to display at the EditText field.
I can't seems to get the value to display at the EditText field after the dialog dismiss. I did try a toast to display the value and it is ok. I *think* the view was not refresh to display the text in the EditText field.
