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.

Why is the textSize attribute ignored in EditText-fields? How can I make the text in those fields smaller, so that ALL cells have the same font size? Why does Android not honor that attribute, even if explicitly set?
I am trying to add a "EditText" Field to an AppWidget. I took the AppWidget example from here: http://developer.android.com/guide/samples/ApiDemos/src/com/example/andr oid/apis/appwidget/index.html and modified it by replacing the TextView with a EditText. It doesnt work... Compiles and runs but the Widget sais "Problem loading Widget" when it shows up.
Maybe an example? Is the default Google Search Widget open source? Can someone give ma a link to the source?
Is there a way to make the screen scroll to allow the text field to be scene?

View 1 Replies View RelatedI have a setup view where the user can enter their name and email and click done when they are finished which navigates them to another activity1. When they are in activity1, and they hit the soft back button on the phone, it takes them screen where they entered their name and email. However, the name and email EditText fields are blank. In the view where the name and email are entered I looked to see if onStart, onCreate, OnPause, onResume,... where being called after the back button was hit, but they are not. Do you know how I can make it so that the EditText fields have the information that was previously entered.

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 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?

I'm trying to understand remote services at the moment and everything works fine, i can start the service and know how to communicate with it through the AIDL-interface. My problem is that the service seems to still run in the same process like the activity it was started from, because the activity crashes too, if there is an error thrown in the Service.
I set the service process to remote ( android:process=":remote" ) so what am i doing wrong? Or what do i have to do to unbind the service-process completely from the activity-process?
Adding an image on EditText works fine. However, copying an image is another problem. When I insert an image on EditText by using ImageSpan it shows correctly, but I copy inserted image, EditText shows me only 'obj'.
View 1 Replies View RelatedI 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.
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.

View 2 Replies View RelatedEvery 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.

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?

View 1 Replies View RelatedI am trying to populate the text of a second EditText widget with the text from the first EditText widget only when the second EditText widget receives focus, the second widget is not empty, and the first widget is not empty. When I run it and click into the second widget it does not populate. When I remove the third constraint ('etxt.getText ().toString().trim() == ""')) it works. so getText() on the second EditText widget is returning something even though the second widget has no initial value other then the text that is displayed via the hint attribute.
