android中的搜索栏小部件？

---

有没有像android默认搜索栏一样的搜索栏小部件？。我只想像默认的搜索栏，我要处理搜索功能。我可以通过使用编辑文本小部件来实现这一点，但我想知道是否有现成的小部件可用？

您可以使用TextWatcher类使编辑文本像搜索栏一样工作。

请参见此处在您使用的onCreate方法中，请参见此处可以使用：

onCreate方法：

// enabling action bar app icon and behaving it as toggle button
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
handleIntent(getIntent());

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.feed, menu);

    // Associate searchable configuration with the SearchView
    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView = (SearchView) menu.findItem(R.id.action_search)
            .getActionView();
    searchView.setSearchableInfo(searchManager
            .getSearchableInfo(getComponentName()));

    return true;

这样，您将在操作栏上看到搜索小部件。我希望它能与你们一起工作。
