My Application need to perform a database search when the user change the text in an EditText view. I need a method like onChange to allow me to know when the text in the EditText changed. How can I detect a change in the EditText view?

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):

I am using an EditText. Is it possible to have a part of text uneditable and the rest editable in the same 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?
i have a listview (i use a custom adapter) with 10 rows and each row has edittext how will i update the content of edittext on the third row after i edit the content of edittext in the first row.
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.

View 2 Replies View RelatedIn the Google Maps app, there's a unique EditText that I'd like to reproduce. If you click "menu" then go to "directions", the "start point" field should begin with "My Location" as the text. The interesting part of this field is its behavior - you cannot edit "My Location" without completely deleting it first. I have a few places where such behavior would be useful, but I can never quite fully reproduce this. There are three challenges involved with this behavior: No matter what the user does, they cannot partially edit the field; it is always fully selected. The keyboard directional keys, rather than moving around the EditText field, change focus. When the user does choose to change the text, the behavior of #1 and #2 disappear and the field acts like a normal EditText.

View 1 Replies View RelatedHow do I turn off the IME-functionality of an EditText?
Or: How do I avoid the display of the IME-keyboard?
I have a layout where my special keyboard sits below the EditText so there's no need to show the IME. Please understand that I cannot implement my keyboard as IME as it is specific for this very EditText and using it in any other context would only cause problems.
I tried to use
getWindow().setSoftInputMode(LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
in the onCreate() of the activity, but that doesn't seem to do anything in this situation.

View 2 Replies View RelatedI have ported the Android to a x86 platform. And i want to detect the USB plug-in.But follow the information about the android.intent.action.MEDIA_MOUNTED in the SDK's DOC, i can't receive the event of the USB's plug-in. i have checked my code and it can receive the other event ( ps:intent action) .
Besides, in the CLI, i could mount the USB device to /sdcard but it couldn't mount automatically. have seen some source code about the mount and mountlistener and it should be effective. my SDK's version is 1.5.
I would like to have my code run slightly differently when running on the emulator than when running on a device. (For example, using 10.0.2.2 instead of a public URL to run against a development server automatically.) What is the best way to detect when an Android application is running in the emulator?
View 9 Replies View RelatedI want to incorporate some Accelerometer code into a Android application im working and want to see if this is possible. Basically what I need is for the code to detect car acceleration motion. I am not wanting to determine speed with the code but just distinguish if the phone is in a car and has accelerated motion (Hence the car is moving for the first time). I have gone through many different accelerometer applications to see if this motion produces a viable profile to go off of and it appears it does. Just looking for something that popups a "Hello World" dialog when it detects your in the car and its moving for the first time down the street. Any help would be appreciated and a simple yes or no its possible would work. I would also be interested in compensating anyone that is capable of doing this as well.
View 2 Replies View RelatedI need to implement HorizontalScrollView which is scrolled to predefined positions (similar to Home behaviour). It works with slow gestures, but does not work with neither flings nor arrow key press.
I hooked to View.onScrollChanged() and it is called when scrolling happened, but I can't determine when scrolling animation ends.
In theory there should be a way to say that fling movement is over. Is there such API?

View 1 Replies View RelatedIs there a way to get a system notification when an app has been uninstalled?I would like to maintain a table of all clients' info currently using my app. However, that seems impossible if there is no way to detect this event. The first solution I can think of is to have an always running service in the background listening for android.intent.action.PACKAGE_REMOVED. But then would that service be killed once the uninstallation process has ended, or would it be stopped just before the process has kicked off? Also even if this is a solution it's has the potential to put off a lot of people when they realise that part of the app is running in the background.
View 2 Replies View RelatedI've asked "how to detect home screen" before. I'm still searching. I noticed when I press "home" button on Android emulator, I got this statement in catalog so I went to ActivityManager to see if I can find a clue there. Here is my findings: 1. I can not instantiate ActivityManager because it's constructor is not public, and it's not a singleton 2. it has a function called: getRunningAppProcesses sounds promising -- would it give me all the running processes? 3. since I can not instantiate ActivityManager I tried to use one of the derived class: RunningAppProcesseInfo to see if I can use it's parent methods: getRunningAppProcesses. Nope.
