How can I open Preference screen by long press from a key of sample keyboard?

Question

I am a beginner about java and android. I am learning about Sample softkeyboard in Android studio. I want to know how I can open Preference Screen by long press on a key (like Globe key) of sample keyboard instead of going to Setting menu of my phone. Thank you. Sorry for my bad English.

Answer 1

Thats the way you can open the preference screen with a button click

   public void onClick(View v) {
   switch (v.getId()) {
   case R.id.btnPrefs:
      Intent intent = new Intent(PreferenceActivity.this,
      PrefsActivity.class);
      startActivity(intent);
      break;

The long click is something like following

btn.setOnLongClickListener(new OnLongClickListener() { 
        @Override
        public boolean onLongClick(View v) {
            // TODO Auto-generated method stub
            return true;
        }
    });
