我无法让hideSoftInputFromWindow工作

Question

一旦搜索完成,我会尝试隐藏软键盘,但我找不到它失败的原因.

我创建了如下搜索菜单:

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {

    String[] mSubActionsTitles = getResources().getStringArray(R.array.sub_actions_array);

    MenuItem item = menu.add(0, R.id.search, 0, mSubActionsTitles[0]);
    searchMenuItem = item;
    item.setIcon(android.R.drawable.ic_menu_search);
    item.setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);

    mSearchView = new SearchView(getActivity());
    mSearchView.setOnQueryTextListener(this);
    mSearchView.setOnCloseListener(this);
    mSearchView.setIconifiedByDefault(true);
    mSearchView.setQueryHint(getString(R.string.label_tvGivePosition));
    item.setActionView(mSearchView);
}

输入文本后,我启动一个AsyncTask()执行HTTP查询的文本.然后,我们收到响应,我调用委托,我试图隐藏键盘:

public synchronized void sitesLoadingFinish(Integer result) {

    searchMenuItem.collapseActionView();
    View view = activity.getCurrentFocus();
    view.clearFocus();
    InputMethodManager imm = (InputMethodManager)getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}

所以searchMenuItem.collapseActionView()很好崩溃,没有问题,但我无法让软键盘关闭.

Answer 1

View view = activity.getCurrentFocus();
view .postDelayed(new Runnable() {
  @Override
  public void run() {
    // TODO Auto-generated method stub
    InputMethodManager keyboard = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
    keyboard.hideSoftInputFromWindow(view, 0);
  }
},50);
