onInputShowListener Android - Is it possible to detect if any soft keyboard is shown?

问题

after fixing another problem in my Android Application, i came to another thing.

It would be important that i can do something, like hide some visual elements, if the SoftKeyboard so a Input like Swipe or the normal Android Keyboard is shown.

I've tried the onConfigurationChange="KeyboardShow" (pseudocode) but had no change to get a event when for example skype got shown.

So now my question is, is there any solution or function or listener, with which i can handle such a action?

I hope someone can help me.

Sincerly, Mike Penz

There might be better approaches, but a possibility is to add: android:configChanges="keyboardHidden" to the manifest. That will fire with any keyboard changes, so the you will need to query the Configuration object

static Configuration prevConf = Configuration();
static int ignoreMasks = Configuration.HARDKEYBOARDHIDDEN_NO|Configuration.HARDKEYBOARDHIDDEN_YES;

onCreate() {
   prevConf = setToDefaults();
}
// all your code here

@Override
public void onConfigurationChanged (Configuration newConfig) {
    int deltas = newConfig.diff (prevConf); // what changed?
    prevConf = newConfig;

    if (delta & ignoreMasks) 
        return; // you're not interested in hard keyboards.

    //  your code here 
}

I suck at bitwise operators, so you might need to work around that.

This is the API documentation:
