I'm trying to make an app which is controlled by a gamepad. I've gotten it to work alright, but Android has some default controls that it uses for navigation when a gamepad is plugged in, such as the B button takes you back a menu. I want to be able to use the buttons that Android has defaults for. Is there a way to disable the default Android controls? I can't find any thing about the default Android gamepad controls, let alone how to disable them.
I figured it out. For anyone who needs this in the future, here's how to do it. When you add in the onKeyDown override command, this is what it looks like.
#Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
return super.onKeyDown(keyCode, event);
}
As I understand it, that return line gives the Android system access to the button presses. However if you make it always return true, the Android system never sees the input. For example:
#Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if(keyCode == KeyEvent.KEYCODE_BUTTON_A)
{
buttonAPressed = true;
}
return true;
}
I don't know if this is the best way to do it, but that's my work around to it. Hope this helps anyone that needs it!
I have a Xamarin Android application with a GestureDetector. On my device (Sony Xperia S5303) and in emulators it works fine. However, on a Samsung Galaxy tablet, the OnSingleTapUp event is fired twice, even though I touch the screen just once. Since the event is checked by the OnSingleTapConfirmed, and the device behaves as if two taps were made, the following method is never called:
public bool OnSingleTapUp(MotionEvent e)
{
if (PersistentContext.LoggedPlayer.Token)
{
if (simpleOnGestureListener.OnSingleTapConfirmed(e))
{
Move(e);
}
return true;
}
return false;
}
The strange thing is, that when clicking on a button, the button method is called just once. Can anybody tell me what might cause this strange behaviour and how to avoid it?
You need to use onSingleTapConfirmed(MotionEvent event) instead. This way android makes sure it's a single tap and doesn't fire the event twice.
Edit: if you are determined to use onSingleTapUp(MotionEvent event), then you can use event.getEventTime()and if the time difference between the first and second events is less than a THRESHOLD like 200ms or something, consider it the unwanted second-time fired tap and ignore it.
Edit 2: Since I don't use Xamarin I might be totally wrong but I think you need to change your code like this: (I mean forget onSingleTapUp completely and move wyour whole code into onSingleTapConfirmed)
#Override
public boolean onSingleTapConfirmed(MotionEvent event) {
if (PersistentContext.LoggedPlayer.Token)
{
Move(e);
return true;
}
return false;
}
Hope it helps and Good Luck!
i'm working on a project wich require the use of a custom soft keyboard developed by some one else. The problem is that the setOnEditorActionListener does not work in a specific windows where a fragment is used. Does not work means that the onEditorAction is not fired at all. The problem appens only with the custom keyboard, with the default one every thing is working well. The problem is that the soft keyboard project is very complex because i don't know soft keyboard logics and I need to solve the problem before tomoroow morning. Does anyone have an idea of this behavior? Please help
this is the part where i set the listener, this code is working all around the project but here, even the first listener's line is not reached
((EditText) getView().findViewById(R.seatDetailCommonHeader.txtName)).setOnEditorActionListener(new OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (event != null && event.getAction() != KeyEvent.ACTION_DOWN) {
return true;
}
// KeyboardHelper.setKeyboardVisibilty(v, false);
executeCheck();
return true;
}
});
i went into further investigations, i put a breakpoint on every method's first line in the keyboard code (which is the one taken from the sdk samples with just some layout modification) and the same EditText in two different activities fires different methods:
in one case (the working one) this methods are fired when action button is clicked:
LatinKeyboard.isInside
LatinKeyboard.isInside
LatinKeyboard.isInside
LatinKeyboard.isInside
LatinKeyboard.isInside
LatinKeyboard.isInside
LatinKeyboard.isInside
LatinKeyboard.isInside
LatinKeyboard.isInside
SoftKeyboard.onKey
SoftKeyboard.isWordSeparator
SoftKeyboard.sendKey
SoftKeyboard.keyDownUp
SoftKeyboard.keyDownUp
SoftKeyboard.updateShiftKeyState
in the other case (the one that is not working) the same methods are fired, plus these:
SoftKeyboard.onFinishInput
SoftKeyboard.onStartInput
SoftKeyboard.updateShiftKeyState
LatinKeyboard.setImeOptions
SoftKeyboard.onStartInputView
hope someone has some idea of this behavior because i'm really in trouble
I'm developing a simple app on PhoneGap for an Android set top box.
I have an image that is usable as a link. When I connect a mouse to the set top box and click the image, the link works. But when I use the remote control and select the image (I see the border around the image so I know it is selected) and I click OK button, the link does not work.
How can I use the remote buttons in the code?
This is very tricky because Google didn't feel like mapping the keys on a remote to an actual key output.
To use the setTopBox, you're going to have to figure out what key codes your Android Set Top Box is using and modify the Activity's onKeyUp event to handle it. We currently have an example of a work-around in this bug however we don't have an agreed API for exposing these buttons to Javascript yet, which is why this bug is still open.
But in short, you'd do something like this:
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_DPAD_UP)
{
sendJavascript("javascript:myJsMethod('UP');");
return true;
}
return super.onKeyDown(keyCode, event);
}
We are working on our first android app and it has been a very enjoyable experience so far. It is almost complete, but before release we are having some considerations ,mainly about android soft keyboard.
We have a couple of EditText fields that are used to enter numbers. We would like to capture the event when user presses enter, and do some calcuations and saving on this callback.
The problem is that we are not getting a fixed event as different phones have different keyboards. Some have 'Done' button and our HTC phones have 'Enter' buttons. We tried using the imeOptions as 'done' but that had no effect on the HTC phones.
We also know that the keyboard can be dismissed by hitting the back button. So my question is if there is a reliable way to know when the user has stopped entering or when the keyboard is hidden, just like textFieldShouldReturn callback in iphone sdk(which will always fire when keyboard goes down, independent of what key caused it to go down)..
In other words, how an android developer handles soft keyboard? I check for KeyEvent.KEYCODE_ENTER on editText onClick() event and do my tasks there.It is working on my HTC android, but not on my friends Nexus phone, which has a done button instead of enter. There onClick is not even called. How a developer handles this?
EDIT: After losing half of my hair, and with the help of some good friends here
I have tried all your suggestions but at the end by using onEditorActionListener along with onKeyListener method did the trick for me. In onEdit callback of onEditorActionListener I checked for KeyCode ACTION_DONE, which did get called on keyboards with done button. On keyboards which has enter onKey gets called. In onKey method I checked for KEYCODE_BACK also, so that hardware back press event also can be handled. I haven't yet found out a android device with done and enter on the keyboard (seriously), still I even handled that case with a flag. Thanks #Femi for suggesting onEditorActionListener, and thanks for all friends for your help. But the answer to my original question
Q: Is there an reliable and easier way to know android soft keyboard resigns (callback that works on every phone)
Ans : No, All methods suggested here and all methods suggested on other sites are not straightforward. And I think handling an event for keyboard return key is the most basic thing for any operating system. Google, are you there?
Since it seems that you are catching the KEYCODE_ENTER event, you might be able to use this: http://developer.android.com/reference/android/widget/TextView.html#setOnEditorActionListener%28android.widget.TextView.OnEditorActionListener%29. In theory this will let you detect whatever the input method end action is (whether its back, done, enter, or whatever) and respond to it.
Let me know if that works for you.
Wouldn't you also need to perform those calculations when the user is leaving the TextView on a hardware keyboard? I wouldn't focus on the keyboard, but on the TextView itself. If so, what you probably want is setTransformationMethod
You'd have to implement a custom TransformationMethod, specifically the method getTransformation, which transforms a source CharSequence into another one. You can then use the onFocusChanged to apply this only when the focus is lost for that TextView.
I found a solution on this SO page:
Intercept back button from soft keyboard
The answer from mhradek has 0 votes but it seems to be working.
The idea is to extend the base layout of your activity so that you can override the dispatchKeyEventPreIme method and do what you want regarding the KeyEvent passed. Note that you are responsible for managing the soft keyboard.
I am using it and I can definitely intercept key strokes (the back button for example) without the soft keyboard "eating" them. I have yet to play more with it in order to see what is possible and what is not.
I hope it helps.
Have you tried implementing custom EditText view, where you override dispatchKeyEventPreIme? Just like in answer posted by Arnaud (referencing Intercept back button from soft keyboard) but instead of using custom layout use custom EditText and override:
#Override
public boolean dispatchKeyEventPreIme(KeyEvent event) {
if(KeyEvent.KEYCODE_BACK == event.getKeyCode()) {
//this hides soft keyboard in super.dispatchKeyEventPreIme(event)
}
return super.dispatchKeyEventPreIme(event);
}
I suggested this solution in this question
I cant believe Google doesnt have a keyboard independant callback for this case
Wow, I cant believe that neither. I am having a similar problem at the moment.
In addition to the IME ACTION I check for focus changes on the EditFields. This is fine for most of the time, but won't work always.
I found a way to be notified when the keyboard is being hidden, but it's not a complete solution yet (and I'm not sure whether it's a good idea), but I don't have the time to continue right now, so I thought I can drop the start of the idea here...:
Write your own EditText(extend EditText) and override onCreateInputConnection. In your onCreateInputConnection return your own implementation of InputConnection (you can simply extend BasicInputConnection.
The InputConnections "finishComposingText()" method is always called when the keyboard is being hidden (also when the user presses the back-key).
This is the code, and maybe someone else has an idea, why the entered text is not shown in this editfield ;-)
public class MyEditText extends EditText{
public MyEditText(Context context) {
super(context);
}
public MyEditText(Context context, AttributeSet attrs) {
super(context);
}
public MyEditText(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
public InputConnection onCreateInputConnection(EditorInfo outAttrs) {
System.out.println("onCreateInputConnection, "+outAttrs.actionId);
return new MyInputConnection(this,true);
}
private class MyInputConnection extends BaseInputConnection{
public MyInputConnection(View targetView, boolean fullEditor) {
super(targetView, fullEditor);
}
#Override
public boolean finishComposingText() {
System.out.println("FINISH");
return super.finishComposingText();
}
}
}

I have not tried this but, reading the documentation, it seems possible.
// From an activity, you can call
if (getResources().getConfiguration().keyboardHidden == Configuration.KEYBOARDHIDDEN_YES) {
// your code here
}
This code is working fine for me with HTC and default Android keyboard:
editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
// handle enter key on keyboard
if (actionId == EditorInfo.IME_ACTION_SEND ||
(event != null && event.getKeyCode() == KeyEvent.KEYCODE_ENTER && event.getAction() == KeyEvent.ACTION_DOWN)) {
if (uid != null) {
// hide keyboard
InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
// perform other stuff
return true;
}
}
return false;
}
});
Using the following in the editText´s XML:
android:imeOptions="actionSend"
Of course you could also use something else like send, just make sure to change it in both the XML and Java code.
