Unable to show keyboard automatically in the SearchView

If you are using SearchView:

<android.support.v7.widget.SearchView
      android:id="@+id/searchView"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:focusableInTouchMode="true"
      android:iconifiedByDefault="true"
      app:showAsAction="always"
      app:iconifiedByDefault="true"/>

Then just add it to your onCreate method :

final SearchManager searchManager = (SearchManager) getSystemService(SEARCH_SERVICE);
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
        searchView.setIconifiedByDefault(false);
        searchView.setFocusable(true);
        searchView.setIconified(false);
        searchView.requestFocusFromTouch();

It works for me.

I encountered this problem with a SearchView that still would not open the keyboard, and was able to do so by adding a 200ms delay:

   mSearchView.setOnQueryTextFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(final View view, boolean hasFocus) {
            if (hasFocus) {
                view.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
                        imm.showSoftInput(view.findFocus(), 0);
                    }
                }, 200);
            }
        }
    });

Fixed!

mSearchView.setOnQueryTextFocusChangeListener(new OnFocusChangeListener() {
                        @Override
                        public void onFocusChange(View view, boolean hasFocus) {
                            if (hasFocus) {
                                showInputMethod(view.findFocus());
                            }
                        }
                    });

And

private void showInputMethod(View view) {
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        if (imm != null) {
          imm.showSoftInput(view, 0);
        }
    }
