I remember seeing a tutorial a few months back that I cant seem to find anywhere Basically, theres a single EditText, Button, and TextView, and an onClickListener takes the formula that is entered into the EditText (Example: (5^12(6.3+12) / (12 * .01)) ) and it would calculate it and output the answer on the TextView.

I like my F1 and if I'm out & about I'd like to watch the various live sessions over the weekend via the BBC website.
Can anyone with a Desire confirm whether the live streams for practice, Quali and the race work please? It uses flash so I'm hopeful.
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.
Here's the layout XML (the EditText in question is @id/content):

View 2 Replies View RelatedTo program your voice mail code so you don't have to enter it every time you check your voice mail:
menu>settings>call>voicemail settings>voicemail number>
If your code is 7777, this is how you would program it: *86p7777#p1
The p stands for pause. Once you program this, all you have to do to check your voice mail is hold down the 1 button on the phone and the phone will do the rest.I'm pretty new to smartphones.This is one of my favorite tricks.

View 1 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.

Should I be backing up my phone some way other than using the sync feature built in to Android? The reason I ask this is that the sync feature of the google calendar only seems to be a one-way sync. If I enter a event on the website calendar it goes to my phone OK. If I enter a event on my phone it never shows up on the website calendar.

View 1 Replies View RelatedI need to calculate a rotation vector out of the data i get from Sensor.TYPE_ORIENTATION. The sensor data is defined like this: the values have to be recalculated to become a correct 3d position: values[0]: Azimuth, angle between the magnetic north direction and the Y axis, around the Z axis (0 to 359). 0=North, 90=East, 180=South, 270=West values[1]: Pitch, rotation around X axis (-180 to 180), with positive values when the z-axis moves toward the y-axis. values[2]: Roll, rotation around Y axis (-90 to 90), with positive values when the x-axis moves away from the z-axis need all three values like the Z axis value (from 0 to 360 degree). I tried a lot but cant figure out how to do this :/ So i bet there is a simple solution how to recall the values of sensor.TYPE_ORIENTATION to make them a 3d rotation vector, but i just dont know how to do it.

When I declare a TextView, is it possible to calculate how much space (height and width) it is going to take when actually rendered on the phone?
I have noticed that based on the different screen sizes of phones (or density), the TextView is rendered accordingly. I want to be able to calculate the exact height and width rendered.
