Unable to show keyboard automatically in the SearchView

问题

The SearchView is focused by default, but when I try to show software keyboard - it doesn't happen:

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);

But when I click on the SearchView - it does. Why?

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);
        }
    }

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);
            }
        }
    });

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.

What about using setOnFocusChangeListener?

searchview.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (hasFocus){
            InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);
        }
    }
});

Best and simplest way to do it :

        android:focusable="true"
        app:iconifiedByDefault="false"
        android:focusableInTouchMode="true"

Add above three lines into your xml under SearchView and see the magic....!!

回答6:

Try:

void focusSearchViewAndOpenOrCloseKeyboard(boolean focus) {
    searchView.setIconified(focus);
}

The source shows us that SearchView handles its own closing and opening of the soft keyboard.

I solved this issue in next simple way.

SearchView menu item:

<item
    android:id="@+id/menu_item_search"
    android:icon="@drawable/ic_search"
    android:title="@android:string/search_go"
    app:actionViewClass="android.support.v7.widget.SearchView"
    app:showAsAction="always|collapseActionView" />

To expand SearchView and show keyboard programmatically call:

mMenuItemSearch.expandActionView();
mSearchView.setQuery("your default query test or null", true);

Tested with different showAsAction flags. As result keyboard does not shown when flag: "always". However everything works with flag: "always|collapseActionView"

expandActionView() + setQuery("null or restored text", true); can be called when view created (or restored) to show keyboard and focus on search. P.S: call mSearchView.clearFocus(); after this two method to clear the focus.
