I am trying to add shortcuts in my app when external keyboard is connected. SHIFT+KEY, this combination is triggering the following event. But Control+KEY and Control key events are not triggered. Can anyone suggest me on this.
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_CTRL_LEFT) {
flag_sellreceipt = KeyEvent.isModifierKey(KeyEvent.KEYCODE_CTRL_LEFT);
int i = KeyEvent.META_CTRL_LEFT_ON;
System.out.println("ctrl is pressed");
}
return
super.onKeyDown(keyCode, event);
}
Note: I have tested this in emulator.

I'm trying to manage the Next event on the Google Keyboard on a Google Nexus 5. I want my application to check user information when the Next button gets pressed.
The code looks like this:
private TextView.OnEditorActionListener GenerateEditorListeners()
{
return new TextView.OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if(actionId == EditorInfo.IME_NULL && event.getKeyCode() == KeyEvent.KEYCODE_ENTER){
if (!finished)
{
if (CheckUserInfo()) finished = true;
}
return true;
}
else
{
return false;
}
}
};
}
On a Samsung Galaxy S4 works perfect, but on a Google Nexus 5 the actionId = 0 and the event = null. So I figure out that the Samsung keyboard works fine with this code, but doesn't happen the same with the Google Keyboard.
Any idea on why it's not wokring for Google's keyboards?
EDIT: I've read in this post that Google keyboard has a bug in some LatinIME keyboards.... I'm using a latin one. If that's the problem, how to solve it?
I could solve it by using the OnKeyListener event:
textUserEmail.setOnKeyListener(new OnKeyListener() {
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if(event.getKeyCode() == KeyEvent.KEYCODE_ENTER){
if (!finished)
{
if (CheckUserInfo()) finished = true;
}
return true;
}
else
{
return false;
}
}
});
Now it works in all keyboards.
How do I consume key events in Android. I have exported my game to a "Google Android Project" and I have tried both overriding the dispatchKeyEvent() and onGenericMotionEvent(), like this:
// For some reason the multiple keyevent type is not supported by the ndk.
// Force event injection by overriding dispatchKeyEvent().
#Override public boolean dispatchKeyEvent(KeyEvent event)
{
Log.d(String.valueOf(event.getDeviceId()), "Control");
Toast.makeText(this, String.valueOf(event.getDeviceId()), Toast.LENGTH_SHORT).show();
if (event.getAction() == KeyEvent.ACTION_MULTIPLE)
return mUnityPlayer.injectEvent(event);
return super.dispatchKeyEvent(event);
}
#Override
public boolean onGenericMotionEvent(MotionEvent event)
{
Log.d(String.valueOf(event.getDeviceId()), "Control");
Toast.makeText(this, String.valueOf(event.getDeviceId()), Toast.LENGTH_SHORT).show();
return true;
}
I have also tried to attach KeyListener handlers directly to the UnityPlayer object, like this:
mUnityPlayer = new UnityPlayer(this);
mUnityPlayer.setOnKeyListener(new View.OnKeyListener()
{
#Override
public boolean onKey(View v, int keyCode, KeyEvent event)
{
Log.d(String.valueOf(event.getDeviceId()), "Control");
Toast.makeText(UnityPlayerNativeActivity.this, String.valueOf(event.getDeviceId()), Toast.LENGTH_SHORT).show();
return true;
}
}
);
But in both cases, the Java code is not triggering. Any ideas why??
So I'm able to get the values of Jostick AXIS by putting the following under the Unity activity in the manifest. This now triggers onGenericMotionEvent(), but not dispatchKeyEvent().
<meta-data
android:name="unityplayer.ForwardNativeEventsToDalvik"
android:value="true" />
I'm assuming this is a bug in (or a 'feature of') unity, so will file a bug report with them directly
I have an physical keyboard connected to my android device. I have an application with two buttons and the following two functions handle the KeyEvent:
public boolean onKeyUp(int keyCode, KeyEvent event) {
if(state==State.INI){
char unicodeChar = (char)event.getUnicodeChar();
Log.d("CHAR", "UP: "+Character.toString(unicodeChar)+" - "+Integer.toString(keyCode));
}
return true;
}
public boolean onKeyDown(int keyCode, KeyEvent event) {
if(state==State.INI){
char unicodeChar = (char)event.getUnicodeChar();
Log.d("CHAR", "DOWN: "+Character.toString(unicodeChar)+" - "+Integer.toString(keyCode));
}
return true;
}
but even it handle the ENTER key doesn't prevent it to be handled by the system :s Per example, i changed the return true to false and i can navigate with the arrow keys between the buttons so with return true it is working for almost every key except ENTER :s
Resolved with:
public boolean dispatchKeyEvent(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.KEYCODE_ENTER) {
Log.d("CHAR","YOU CLICKED ENTER KEY");
return false;
}
return super.dispatchKeyEvent(e);
};
I've noticed that the 'back' request used to be made at the point a user pressed down on the 'back' key but at some point this was changed so that a 'back' request is made instead at the point the 'back' key is released. (Correct me if I am wrong!) Does anyone know from which SDK (or API Level) exactly this change was made effective? I think it was SDK 2.0 (API Level 5) and hence have the code in my Activity as follows but would like to be certain...
#Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if (keyCode == KeyEvent.KEYCODE_BACK)
{
if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.ECLAIR)
handleBackRequest();
return true;
}
return super.onKeyDown(keyCode, event);
}
#Override
public boolean onKeyUp(int keyCode, KeyEvent event)
{
if (keyCode == KeyEvent.KEYCODE_BACK)
{
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.ECLAIR)
handleBackRequest();
return true;
}
return super.onKeyUp(keyCode, event);
}
Use onBackPressed() for Android 2.0 and higher. Use onKeyDown() for Android 1.6.
With the code in my previous post I was getting some unwanted behaviour (when dialogs, the android keyboard etc were showing up) and on CommonsWare's advice, changed my code to the following and it seems to be working alright for the different SDKs...
#Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if (keyCode == KeyEvent.KEYCODE_BACK
&& android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.ECLAIR)
{
onBackPressed();
return true;
}
return super.onKeyDown(keyCode, event);
}
#Override
public void onBackPressed()
{
// handle back request here
}
... Let me know please if there's anything here not quite right!
I am sincerely trying to display alert box onClick of Home key, but I am not succeeded. So please help me to write the code otherwise, show me the code.
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if (keyCode == KeyEvent.KEYCODE_BACK )
{
finish();
return false;
}
else if (keyCode == KeyEvent.KEYCODE_HOME)
{
finish();
return false;
}
return super.onKeyDown(keyCode, event);
}
it is not possible to intercept KEYCODE_HOME by external applications:
http://code.google.com/p/android/issues/detail?id=1979
I don't think you can intercept HOME key presses. It is reserved to ensure that you don't get locked within any application.
KEYCODE_HOME : This key is handled by the frame work and is never delivered to applications.
So you can't use it
