android - 软键盘上的搜索图标

Question

我有一个用于 MenuItems 的 searchIcon 的 ActionLayout。这个 ActionLayout 有一个 AutoCompleteTextView，它有imeOption = "actionSearch".

但是当我单击 menuItems 并出现 ActionLayout 时，会弹出软键盘，但它仍然有换行键而不是 searchIcon。

活动代码：

private AutoCompleteTextView mEtSearchbar;
private MenuItem mSearchbar;

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) { 

    case R.id.searchIcon:

        mEtSearchbar.clearFocus();
        (new Handler()).postDelayed(new Runnable() {
            public void run() {
                mEtSearchbar.dispatchTouchEvent(MotionEvent.obtain(
                        SystemClock.uptimeMillis(),
                        SystemClock.uptimeMillis(),
                        MotionEvent.ACTION_DOWN, 0, 0, 0));
                mEtSearchbar.dispatchTouchEvent(MotionEvent.obtain(
                        SystemClock.uptimeMillis(),
                        SystemClock.uptimeMillis(), MotionEvent.ACTION_UP,
                        0, 0, 0));
            }
        }, 100);
        return true;
    default:
        return super.onOptionsItemSelected(item);
    }
}

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    // TODO Auto-generated method stub
    inflater.inflate(R.menu.m_menu, menu);


    mSearchbar = (MenuItem) menu.findItem(R.id.searchIcon);
    View actionview = mSearchbar.getActionView();
    mEtSearchbar = ((AutoCompleteTextView) actionview
            .findViewById(R.id.search_editText));
    final ImageView searchImage = ((ImageView) actionview
            .findViewById(R.id.search_image));
    searchImage.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {

            String s = mEtSearchbar.getText().toString();

                Intent intent = new Intent(getSherlockActivity(),
                        SearchActivity.class);
                intent.putExtra("search_string", s);
                startActivity(intent);
        }
    });

    mEtSearchbar
            .setOnEditorActionListener(new TextView.OnEditorActionListener() {

                @Override
                public boolean onEditorAction(TextView v, int actionId,
                        KeyEvent event) {
                    if (actionId == EditorInfo.IME_ACTION_SEARCH) {

                        searchImage.performClick();
                        return true;
                    }
                    return false;
                }
            });

    super.onCreateOptionsMenu(menu, inflater);
}

    <AutoCompleteTextView

        android:layout_toLeftOf="@id/search_image"
        android:hint="Search"
        android:imeOptions="actionSearch" />

</RelativeLayout>
