ActionBar SearchView未在横向模式下完全展开

Question

使用操作栏搜索界面时,窗口小部件将以纵向模式展开以占据屏幕的整个宽度,但在横向模式下会停止缩短.

有没有办法在SearchView上设置扩展布局参数,以便在用户键入搜索时完全填充操作栏？

注意:我目前没有使用ActionBar Sherlock

编辑:这是我为了扩展全宽而做的.

searchView.setOnSearchClickListener(new OnClickListener() {
    private boolean extended = false;

    @Override
    public void onClick(View v) {
        if (!extended) {
            extended = true;
            LayoutParams lp = v.getLayoutParams();
            lp.width = LayoutParams.MATCH_PARENT;
        }
    }

});

Answer 1

MenuItemCompat的SearchView有一个名为maxWidth的属性.

    final MenuItem searchItem = menu.findItem(R.id.action_search);
    final SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
    searchView.setMaxWidth(xxx);

使用屏幕宽度而不是xxx offcourse

你尝试过类似的事情吗？

editView.setOnKeyListener(new OnKeyListener() {
    private boolean extended = false;

    @Override
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        if (!extended && event.getAction() == KeyEvent.ACTION_DOWN) {
            extended = true;
            LayoutParams lp = v.getLayoutParams();
            lp.width = LayoutParams.MATCH_PARENT;
        }

        return false;
    }

});
