Android如何关注ActionBar searchView

Question

您好我需要在searchView中放置一些文本并关注/展开searchView小部件。

这是我尝试但它不起作用

@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();

Answer 1

尝试使用searchView.setIconified(false)。这对我有用：

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();
}

这是另一种解决方案。

@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;
}

这对我有用：

        @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;
        }

Answer 4

对我来说，以下工作：

@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();
        }
    });

我使用android.support.v7.widget.SearchView。当试图设置mSearchView.setIconified(false);时，它进入了一个无限循环。

Answer 5

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

会做的。

Answer 6

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

这是SearchView中的代码

setIconified（）对我有用

Answer 7

在活动xml中，您可以使用以下行：

android:iconifiedByDefault="false"

Answer 8

如果通过菜单配置创建SearchView，我将使用菜单项展开操作视图。

private var searchMenuItem: MenuItem? = null

// create search menu item
override fun onCreateOptionsMenu(menu: Menu?): Boolean {
    menuInflater.inflate(R.menu.search_menu, menu)
    searchMenuItem = menu?.findItem(R.id.action_search)
    val searchManager = getSystemService(Context.SEARCH_SERVICE) as SearchManager
    (searchMenuItem?.actionView as? SearchView)?.apply {
        setSearchableInfo(searchManager.getSearchableInfo(componentName))
    }
    return super.onCreateOptionsMenu(menu)
}


override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_search)
    setSupportActionBar(findViewById(R.id.toolbar))
    // Execute 'expandActionView' delayed 
    // because I want to focus field only when first start.
    Handler().postDelayed({
        // show field and focus it.
        searchMenuItem?.expandActionView()
    }, 500)
}

我在onCreateOptionsMenu中实现了它，它工作正常。你不需要使用setIconified(false);

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.main, menu);

        // Associate searchable configuration with the SearchView
        SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
        searchView.setMaxWidth(Integer.MAX_VALUE);
        searchView.setOnClickListener(view -> menu.findItem(R.id.action_sleep_timer).setVisible(false));
        searchView.setOnCloseListener(() -> {
            menu.findItem(R.id.action_sleep_timer).setVisible(true);
            return false;
        });
        searchView.setOnSearchClickListener(view -> {
            menu.findItem(R.id.action_sleep_timer).setVisible(false);
            searchView.requestFocus();
        });
return true;
    }
