使用SearchView的Android abs，onQueryTextListener无效 [英] Android abs with SearchView, onQueryTextListener not working

问题描述

我正在尝试使用带有操作栏sherlock的SearchView支持v4版本。

I'm trying to use the SearchView Support v4 version with action bar sherlock.

所以我在操作栏中有我的搜索按钮 - >当我触摸它时键盘显示和searchBar也是如此。

So i have my search button in the action bar -> when i touch it the keyboard show up and the searchBar too.

我的问题是我需要使用onQueryTextSubmit和onQueryTextChange上的侦听器，但它们永远不会被触发。我需要使用searh查询字符串并使用它做自定义内容。

My problem is that i need to use the listeners onQueryTextSubmit and onQueryTextChange but they are never fired. I need to use the searh query string and do custom stuff with it.

这是完整的activity.java

Here is the full activity.java

public class ActivityMain extends SherlockFragmentActivity implements OnQueryTextListener, DialogFragmentListener {
    /**
     * PRIVATE ATTRIBUTES
     */
    private static final String TAG                             = "ActivityMain";
    private ViewPager           _viewPager;
    private TabsAdapter         _tabsAdapter;
    private DialogFiltre        _dialogFiltre;
    private String              _searchCurrentQuery;
    // data
    private boolean             _doubleBackToExitPressedOnce    = false;


    @Override
    public boolean onPrepareOptionsMenu(Menu menu) {

        menu.clear();
        switch ((int) _viewPager.getCurrentItem()) {
            case 0:
                getSupportMenuInflater().inflate(R.menu.empty_menu, menu);
                break;
            case 1:
                getSupportMenuInflater().inflate(R.menu.action_bar_menu, menu);
                break;
            case 2:
                getSupportMenuInflater().inflate(R.menu.empty_menu, menu);
                break;
        }
        return super.onPrepareOptionsMenu(menu);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        getSupportMenuInflater().inflate(R.menu.action_bar_menu, menu);
        MenuItem searchItem = menu.findItem(R.id.search);
        SearchView searchView = (SearchView) searchItem.getActionView();
        searchView.setSubmitButtonEnabled(true);
        searchView.setOnQueryTextListener(queryTextListener);
        return true;
    }

    @Override
    public boolean onQueryTextSubmit(String query) {

        Log.i(TAG, "onQueryTextSubmit--");
        onSearchClicked(query);
        // hide keyboard
        InputMethodManager inputManager = (InputMethodManager) this.getSystemService(Context.INPUT_METHOD_SERVICE);
        inputManager.hideSoftInputFromWindow(this.getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
        return false;
    }

    @Override
    public boolean onQueryTextChange(String newText) {

        Log.d(TAG, "onQueryTextChange--");
        _searchCurrentQuery = newText.toString();
        EtablissementApplication._adapter.getFilter().filter(_searchCurrentQuery);
        return true;
    }

    private void onSearchClicked(String query) {

        Log.d(TAG, "onSearchClicked--");
        _searchCurrentQuery = query.toString();
        EtablissementApplication._adapter.getFilter().filter(_searchCurrentQuery);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {

        switch (item.getItemId()) {
            case android.R.id.home:
                getSupportActionBar().setDisplayHomeAsUpEnabled(false);
                break;
            case R.id.search:
                break;
            case R.id.menu_filtre:
                _dialogFiltre = DialogFiltre.newInstance(R.string.menu_filtre, this);
                _dialogFiltre.setValidDialogListener(this);
                _dialogFiltre.show(getSupportFragmentManager(), null);
                break;
        }
        return super.onOptionsItemSelected(item);
    }

推荐答案

您正在尝试使用新的SearchView而不是使用SupportMenuInflater创建的。
您将侦听器设置为您在屏幕上看到的不同SearchView。
此外，每次调用onPrepareOptionsMenu时，都会创建新的SearchView，因此它没有设置侦听器。

You are trying to use a new SearchView instead of using the one created by the SupportMenuInflater. You setting the listener to different SearchView that you see on the screen. Also, every time onPrepareOptionsMenu is called, new SearchView is created, and thus it has no listeners set.

尝试执行onPrepareOptionsMenu，如下所示：

Try to do onPrepareOptionsMenu like this:

@Override
public boolean onPrepareOptionsMenu(Menu menu) {

    menu.clear();
    switch ((int) _viewPager.getCurrentItem()) {
        case 0:
            getSupportMenuInflater().inflate(R.menu.empty_menu, menu);
            break;
        case 1:
            getSupportMenuInflater().inflate(R.menu.action_bar_menu, menu);
            MenuItem searchItem = menu.findItem(R.id.search);
            SearchView searchView = (SearchView) searchItem.getActionView();
            searchView.setSubmitButtonEnabled(true);
            searchView.setOnQueryTextListener(queryTextListener);
            break;
        case 2:
            getSupportMenuInflater().inflate(R.menu.empty_menu, menu);
            break;
    }
    return super.onPrepareOptionsMenu(menu);
}

并删除重写方法

@Override
public boolean onCreateOptionsMenu(Menu menu) { }
