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.

I have a TextView in my xml layout file. I'd like to get it and change my text when I click this button.
But I can't get it (the TextView) unless I make it as a value of a static member of this class and pass it to the constructor. I believe I am missing a big point here, so i'd be very thankful if you could explain how this is meant to be done ?

View 1 Replies View RelatedI notice that some of the base applications in Android are using this little control (View in Android terms I guess) that shows the contact picture. When you click on the picture it shows all the ways of contacting the person (phone, sms, talk, facebook). I see this little View used in the contact app, sms app, twitter for android, facebook for android etc.
Is there a library or a way of getting this working on my own application or do I need to write this from scratch?
I have a gallery widget and in that i had a view with linear layout which has a edit text inside. When it launches on device the edittext box shows but has no text visible.
However when i scroll to next view in gallery it shows text and when it comes to focus and centered the text disappears.
If i replace gallery with grid or a horizontal view I can see the text on edit text.
Can you please advise what I might be doing wrong here. Why the text disappears.
I need to create a form to insert a username for my application, so I want the user to be able to insert only letters, numbers and some symbols.
I noticed that there is not a simple way to do it (while if I needed a numeric fields the implementation would be easy).
The most easy way that I found is based on the usage of the attribute "digits" of the EditText View. Hence, I inserted a string with the list of characters to be accepted (example: 1234abce).
The filter works as expected. When the keyboard appears, the user can insert only the characters that I specified in the "digits" field. The problem is that the keyboard does not accept the "Enter" key, so there is no way for the user to click/touch Enter so to confirm their Input and make the on-screen keyboard to disappear.
I am new so I may not explain the situation well. Please let me know if you need more info.
I am trying to implement a listview like this:
[textview][button][checkbox]
[textview][button][checkbox]
[textview][button][checkbox]
[textview][button][checkbox]
I want other checkbox unchecked automatically when I click one of them. So it is like a single choice. I write following codes which can implement multiple choice but when I try to switch it to single choice I got trouble.
in checkBoxOnClickListener I cannot find other (checkbox)view and toggle them. Any suggestion pals? Let me know if you think my express skills poor. code...

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.
I have a res/layout/main.xml including these elements and others:
<some.package.MyCustomView android:id="@+id/foo" (some other params) />
<TextView android:id="@+id/boring" (some other params) />
In my Activity's onCreate, I do this:
setContentView(R.layout.main);
(TextView) boring = findViewById(R.id.boring);
// ...find other elements...
MyCustomView foo = (MyCustomView) findViewById(R.id.foo);
if (foo == null) { Log.d(TAG, "epic fail"); }
The other elements are found successfully, but foo comes back null. MyCustomView has a constructor MyCustomView(Context c, AttributeSet a) and a Log.d(...) at the end of that constructor appears successfully in logcat just before the "epic fail".
findViewById() returns null for custom component in layout XML, not for other components. Why is foo null?

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):

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?
I'm using hierarchyviewer to look through a widget that I'm using. (TimePicker).

Tried my_picker.findViewWithTag("decrement"); but that returns null.
I would like to know whether there is a way to insert/inject a <string> element defined in an XML file into another <string> element, doing that just with XML.
For example I could have:
<string name="author">Francesco</string>`
and I am looking for something like:
<string name="about_application">Author: @string/author</string>`
so that getString(R.string.about_application) would result in "Author: Francesco".
I know that I could combine the two elements in Java code using String.format(string, formatArgs)like for example:
<string name="author">Francesco</string>
<string name="about_application">Author: %1$s</string>`
and then in code use
String.format(getString(R.string.about_application), getString(R.string.author))
but I would like to do it in XML directly. Can anyone suggest me a way to do it?
