hideKeyboard method in class in android

Question

private void hideKeyboard() {
    try {
        // Close Soft Keyboard
        InputMethodManager inputManager = (InputMethodManager)
                mContext.getSystemService(Context.INPUT_METHOD_SERVICE);

        inputManager.hideSoftInputFromWindow(rootView.getWindowToken(),
                InputMethodManager.HIDE_NOT_ALWAYS);
    } catch (Exception keyboardHideExp) {
        Log.d("eEmp/HideKbExp", "Exception raised due to " + keyboardHideExp.toString());
    }
}

This was used in fragment. I need to use same method in my class but giving error at rootView. How can I access in my class.

inputManager.hideSoftInputFromWindow(rootView.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);

I am new to android.

Any help would be appreciated.

Do you want to hide keyBoard on any action? – Jan 23 '18 at 11:06 — , Jan 23 '18 at 11:06

Try this code.

Context mcontext;
View rootView;
classConstructor(Context context, View view){
this.mcontext = context;
this.rootView = view;
}
private void hideKeyboard()
{
try {
// Close Soft Keyboard
InputMethodManager inputManager = (InputMethodManager)
                mContext.getSystemService(Context.INPUT_METHOD_SERVICE);

inputManager.hideSoftInputFromWindow(rootView.getWindowToken(),
                InputMethodManager.HIDE_NOT_ALWAYS);
} catch (Exception keyboardHideExp) {
        Log.d("eEmp/HideKbExp", "Exception raised due to " + keyboardHideExp.toString());
}
}

In this lines this.mcontext = context; this.rootView = view; Do we need this? – Shivam Oberoi Jan 23 '18 at 11:10
This depends on how are you doing. – singh.indolia Jan 23 '18 at 11:13
if we have this.context = context; this.view = view; then we need this but for different names we dont need this. in this case we can specify it as-: mcontext = context; rootView = view; – Shivam Oberoi Jan 23 '18 at 11:14

You need parent View. How your method is getting rootView variable?
The simplest way is:

In YourClass.class

public void closeKeyboard(Context context, View view) {
   InputMethodManager inputMethodManager =(InputMethodManager)context.getSystemService(Activity.INPUT_METHOD_SERVICE);
   inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
}

Or instead of view.getWindowToken() use context.getCurrentFocus().getWindowToken().

In YourActivity.class

EditText editText = findViewById(R.id.my_edit_text);
new YourClass().closeKeyboard(this, editText);

The EditText should be in activity/fragment layout.

giving error at view@EJusius – kalyan Jan 23 '18 at 11:14
Is a view in your fragment and did you find it by id before setting there? @kalyan – Dumbo Jan 23 '18 at 11:17
even though giving error at getCurrentFocuss()@EJusius – kalyan Jan 23 '18 at 11:19
do I need to create view variable in my class? @EJusius – kalyan Jan 23 '18 at 11:19
You need to get it from your fragment or activity layout @kalyan – Dumbo Jan 23 '18 at 11:20
`View` is superclass of for example `EditText`, `Button`, `TextView` an other widgets... @kalyan – Dumbo Jan 23 '18 at 11:21

You can use this as you using Fragment.

private void hideKeyBoard() {
    if (getActivity().getCurrentFocus() != null) {
        InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(getActivity().getCurrentFocus().getWindowToken(), 0);
    }
}

It's works for me...
