但是当我单击menuItems并显示ActionLayout时,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));
                mEtSearchbar.dispatchTouchEvent(MotionEvent.obtain(
                        SystemClock.uptimeMillis(),MotionEvent.ACTION_UP,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);
}

如何在软键盘上有一个searchIcon或至少一个完成按钮,点击它必须执行我在ActionLayout中的searcIcon点击

谢谢
