onConfigurationChanged doesn't work - android

I am trying to #Override onConfigurationChanged because I want to know when the keyboard down and when it is up but nothing happened.
What can I do? This is my source:
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Checks whether a hardware keyboard is available
if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_NO) {
Toast.makeText(this, "keyboard visible", Toast.LENGTH_SHORT).show();
} else if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_YES) {
Toast.makeText(this, "keyboard hidden", Toast.LENGTH_SHORT).show();
}
}
I also added to the manifest this line
android:configChanges="keyboard|keyboardHidden"


Try comparing newConfig.keyboardHidden==Configuration.KEYBOARDHIDDEN_YES This applies for all the keyboards whether it is attached to the device or not.

how to keep my app language without changing when changing screen orientation?

I finished my app with multi languages , but when the device orientation is changed to landscape then app's language is changed .
can I use (onSaveInstanceState) method to keep app language without changing when rotating screen?
what is the code I have to insert ??

Try this in your manifest
<activity
android:name=".MainActivity"
android:configChanges="keyboardHidden|orientation|screenSize">
</activity>
And then
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// you can do something here
if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
// orientation_landscape
Toast.makeText(this, "orientation_landscape", Toast.LENGTH_SHORT).show();
} else {
// orientation_portrait
Toast.makeText(this, "orientation_portrait", Toast.LENGTH_SHORT).show();
}
}

How to disable only Reverse screen orientations in android activity

Is there any way to disable Reverse Landscape and Reverse portrait orientations in an android activity. I used the below code.but reverse landscape is coming on that.
rotation = ((WindowManager) getSystemService(WINDOW_SERVICE)).getDefaultDisplay().getRotation();
System.out.println("Rotation Value : " +rotation);
if(rotation==0){
System.out.println("portrait");
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);}
if(rotation==1){
System.out.println("landscape");
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);}
if(rotation==2 )
{
System.out.println("reverse portrait");
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LOCKED);
}
if(rotation==3)
{
System.out.println("reverse landscape");
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LOCKED);
}

Add android:configChanges="keyboardHidden|orientation" to your AndroidManifest.xml. This tells the system what configuration changes you are going to handle yourself, in this case by doing nothing.
<activity
android:name="MainActivity"
android:screenOrientation="portrait" //This line only if you want to lock your screen Orientation
android:configChanges="keyboardHidden|orientation|screenSize">
Check http://developer.android.com/reference/android/R.attr.html#configChanges for more details.
Then override onConfigurationChanged :
http://developer.android.com/guide/topics/resources/runtime-changes.html
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Checks the orientation of the screen
if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
Toast.makeText(this, "landscape", Toast.LENGTH_SHORT).show();
} else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
Toast.makeText(this, "portrait", Toast.LENGTH_SHORT).show();
}
}

Android - onConfigurationChanged is not called when keyboard show/hidden

I need to detect hidden key board when hidden keyboard is pressed
My source code
<activity
android:name="com.teamios.info.activity.MainScreenActivity"
android:screenOrientation="landscape"
android:theme="#style/Theme.MyScreenTranNorman"
android:configChanges="orientation|keyboardHidden"
android:windowSoftInputMode="stateUnchanged|adjustPan" />
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
Toast.makeText(this, "keyboard visible", Toast.LENGTH_SHORT).show();
}
I tested in samsung galaxy nexus phone android os 4.2.1, but Toast didn't show when keyboard hidden
Please help me.

<activity
android:name="com.teamios.info.activity.MainScreenActivity"
android:theme="#style/Theme.MyScreenTranNorman"
android:configChanges="orientation|keyboardHidden"
android:windowSoftInputMode="stateUnchanged|adjustPan" />
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_NO) {
Toast.makeText(this, "keyboard visible", Toast.LENGTH_SHORT).show();
} else if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_YES) {
Toast.makeText(this, "keyboard hidden", Toast.LENGTH_SHORT).show();
}
}
And add
<activity android:name=".MyActivity" android:screenOrientation="landscape " > </activity>
in menifest class.

Did you add android:configChanges="keyboardHidden" in your manifest file ?

Is there a way to tell if the soft-keyboard is shown?

is there a way to tell if the softkeyboard is shown in an activity or not?
I tried
InputMethodManager manager = (InputMethodManager)
getSystemService(getApplicationContext().INPUT_METHOD_SERVICE);
manager.isActive(v)
but isActive returns false only before the first time the keyboard is shown, but if the kb appears and then dismissed, isActive returns true also.
so is there any other method to check for this issue.
thanks

According to this POST
You cannot detect if soft keyboard is shown or not, but you can indirectly know that a soft key board is shown by knowing that the View of your activity is resized.
Imagine you have a ListView and at the bottom an EditText, you want to go to the bottom of the list when a soft keyboard is shown after user clicks the EditText.
You need to implement a subclass of ListView, then use it in your ListActivity or Activity or View.
public class ThreadView extends ListView {
public ThreadView(Context context, AttributeSet attributeSet) {
super(context, attributeSet);
}
#Override
protected void onSizeChanged(int xNew, int yNew, int xOld, int yOld) {
super.onSizeChanged(xNew, yNew, xOld, yOld);
if (yOld > yNew) {
setSelection(((ListAdapter) getAdapter()).getCount() - 1);
}
}
}
Hope this helps
PS. "check Configuration Changes" only works for hand keyboard.

You can detect the state AND coordinates of the software keyboard, using dumpsys shell command.
Because dumpsys requires permission.android.DUMP, which is a system application permission, you have two options: 1. use a rooted device to grant this permission. 2. override the problem using adb as described in my other answer.
Now, run the following command: dumpsys window InputMethod | grep "mHasSurface" to get the data you are looking for.

This is my idea. It is untested.
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Checks whether a keyboard is available which is not hard keyboard
if ((newConfig.keyboardHidden == Configuration.HARDKEYBOARDHIDDEN_NO)&&(newConfig.keyboardHidden != Configuration.KEYBOARDHIDDEN_NO)) {
Toast.makeText(this, "soft keyboard visible", Toast.LENGTH_SHORT).show();
} else if (newConfig.keyboardHidden == Configuration.KEYBOARDHIDDEN_YES) {
Toast.makeText(this, "soft keyboard hidden", Toast.LENGTH_SHORT).show();
}
}

Please check Configuration Changes for your Activity
This for your AndroidManifest.xml
and this for your Activity class http://developer.android.com/reference/android/app/Activity.html#onConfigurationChanged(android.content.res.Configuration)
You will need to #Override the public method onConfigurationChanged(android.content.res.Configuration) of your Activity to be able to handle, for example, these values:
hardKeyboardHidden,
keyboard,
keyboardHidden
For all possible values check http://developer.android.com/reference/android/content/res/Configuration.html
You will see there something like this:
HARDKEYBOARDHIDDEN_NO
HARDKEYBOARDHIDDEN_UNDEFINED
HARDKEYBOARDHIDDEN_YES
KEYBOARDHIDDEN_NO
KEYBOARDHIDDEN_UNDEFINED
KEYBOARDHIDDEN_YES
KEYBOARD_12KEY
KEYBOARD_NOKEYS
KEYBOARD_QWERTY
KEYBOARD_UNDEFINED
Also there you will be able to read something like this:
public int hardKeyboardHidden // A flag indicating whether the hard keyboard
// has been hidden.
public int keyboard The kind of keyboard attached to the device.
public int keyboardHidden A flag indicating whether any keyboard is available.
UPDATE:
Here is a specific example of what I´m talking about:
http://developer.android.com/guide/topics/resources/runtime-changes.html
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Checks the orientation of the screen
if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
Toast.makeText(this, "landscape", Toast.LENGTH_SHORT).show();
} else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
Toast.makeText(this, "portrait", Toast.LENGTH_SHORT).show();
}
// Checks whether a hardware keyboard is available
if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_NO) {
Toast.makeText(this, "keyboard visible", Toast.LENGTH_SHORT).show();
} else if (newConfig.hardKeyboardHidden ==
Configuration.HARDKEYBOARDHIDDEN_YES) {
Toast.makeText(this, "keyboard hidden", Toast.LENGTH_SHORT).show();
}
}

android keyboard open issue

How can i know if the keyboard is open or not?

This is available on the Configuration class. You can get the current Configuration via getResources().getConfiguration() from your Activity or other Context.

That way =)
public boolean isKeyboardVisible(){
// Checks whether a hardware keyboard is visible
if (getResources().getConfiguration().hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_NO) {
return true;
} else if (getResources().getConfiguration()..hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_YES) {
return false;
}
}
