您应该使用内置的android SearchView，根据android用户界面模式，这一点很好 menu.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".ui.home.activities.TransactionSearchActivity">
<item
android:id="@+id/action_search"
android:icon="@android:drawable/ic_menu_search"
android:title="@string/search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="ifRoom" />
</menu>
确保膨胀菜单：D小部件名称为：
android.support.v7.widget.SearchView <item
android:id="@+id/action_search"
android:icon="@drawable/abc_ic_search_api_mtrl_alpha"
android:title="@string/srch"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="ifRoom|collapseActionView" />
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
// Retrieve the SearchView and plug it into SearchManager
final SearchView searchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.action_search));
SearchManager searchManager = (SearchManager) getSystemService(SEARCH_SERVICE);
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
return true;
}
MaterialDesignandroid:icon="@drawable/abc_ic_search_api_mtrl_alpha"
你能再看看我的帖子吗？我应该使用intent吗？在使用此选项菜单的同一活动中更新数据。此操作不需要任何意图。因此，当单击后退按钮（编辑文本旁边）时，它将显示一月列表视图？而不是获取“searchPlate”编辑文本并使用
searchPlate.setHint（“搜索”）searchView.setQueryHint（“Search”）.Sir我应该在单击搜索图标时使用intent，以便在editText填充值时显示相关数据吗？这取决于您的期望，在我的回答中，您可以使用intent而不使用intent。android:icon=“@android:drawable/ic\U menu\u search”如果您已经更新到Android X，请在XML和Java类中使用androidx.appcompat.widget.SearchView。
