Android how to focus ActionBar searchView

问题:

Hello i need to put some text inside the searchView and focus/expand the searchView widget.

this is what i tried but it doesn't work

@Override
public boolean onCreateOptionsMenu(final Menu menu) {
...
    SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
    searchView.setQuery(this.filtro, false);
    searchView.setFocusable(true);
    searchView.requestFocus();
    searchView.requestFocusFromTouch();

回答1:

Try using searchView.setIconified(false). This worked for me:

public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    ActionBar actionBar = getActionBar();
    SearchView searchView = new SearchView(this);
    actionBar.setCustomView(searchView);
    actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
    searchView.setQuery("test",true);
    searchView.setFocusable(true);
    searchView.setIconified(false);
    searchView.requestFocusFromTouch();
}

Here is another solution.

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main_menu, menu);
    MenuItem menu_search = menu.findItem(R.id.menu_search);


    menu_search.setOnActionExpandListener(new OnActionExpandListener() {
        @Override
        public boolean onMenuItemActionCollapse(MenuItem item) {
            // Do something when collapsed
            return true;  // Return true to collapse action view
        }

        @Override
        public boolean onMenuItemActionExpand(MenuItem item) {
            //get focus
            item.getActionView().requestFocus();
            //get input method
            InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.toggleSoftInput(0, InputMethodManager.HIDE_NOT_ALWAYS);
            return true;  // Return true to expand action view
        }
    });
    return true;
}

This works for me:

        @Override
        public boolean onMenuItemActionExpand(MenuItem item)
        {
            if (sm.isMenuShowing()) {
                sm.toggle();
            }
            searchView.setIconified(true);
            KeyEvent event = new KeyEvent(KeyEvent.ACTION_DOWN, 32);
            searchView.onKeyDown(32, event);
            return true;
        }

For me the following works:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    ...
    MenuItem miSearch = menu.findItem(R.id.menu_search);
    SearchView mSearchView = (SearchView) miSearch.getActionView();

    mSearchView.setOnSearchClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            mSearchView.setFocusable(true);
            mSearchView.requestFocusFromTouch();
        }
    });

I use android.support.v7.widget.SearchView. When tried to set mSearchView.setIconified(false); it entered into an infinite loop.

回答5:

searchView.setQuery("typeAnything",true);
searchView.setFocusable(true);

will do the trick.

回答6:

public void setIconified(boolean iconify) {
    if (iconify) {
        onCloseClicked();
    } else {
        onSearchClicked();
    }
}

this is code in SearchView

setIconified() is worked for me

In the activity xml you can use this line:

android:iconifiedByDefault="false"
