我在屏幕上创建活动。我在工具栏中阅读了很多关于SearchView的教程,并在我的活动中实现了它并且它可以工作(上面的代码)。但是如何制作这个下拉列表呢?感谢您的想法,链接或代码。
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.second_activity_menu, menu);
MenuItem searchItem = menu.findItem(R.id.second_toolbar_search);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
SearchManager searchManager =
(SearchManager) getSystemService(Context.SEARCH_SERVICE);
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
// ...
}

在您的gradle中添加此依赖项:
dependencies {
compile 'com.miguelcatalan:materialsearchview:1.0.0'
}
将此添加到您的主要活动:
<RelativeLayout
android:id="@+id/toolbar_container"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="@color/theme_primary" />
<com.miguelcatalan.materialsearchview.MaterialSearchView
android:id="@+id/search_view"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</RelativeLayout>
创建一个菜单文件:
<item
android:id="@+id/action_search"
android:icon="@drawable/ic_action_action_search"
android:orderInCategory="100"
android:title="@string/abc_search_hint"
app:showAsAction="always" />
将此添加到您的MainActivity:
MaterialSearchView searchView = (MaterialSearchView) findViewById(R.id.search_view);
searchView.setOnQueryTextListener(new MaterialSearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String query) {
//Do some magic
return false;
}
@Override
public boolean onQueryTextChange(String newText) {
//Do some magic
return false;
}
});
searchView.setOnSearchViewListener(new MaterialSearchView.SearchViewListener() {
@Override
public void onSearchViewShown() {
//Do some magic
}
@Override
public void onSearchViewClosed() {
//Do some magic
}
});
这是OnActivityResult:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == MaterialSearchView.REQUEST_VOICE && resultCode == RESULT_OK) {
ArrayList<String> matches = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
if (matches != null && matches.size() > 0) {
String searchWrd = matches.get(0);
if (!TextUtils.isEmpty(searchWrd)) {
searchView.setQuery(searchWrd, false);
}
}
return;
}
super.onActivityResult(requestCode, resultCode, data);
}
在字符串res中创建一些数组列表:
<string-array name="query_suggestions">
<item>Android</item>
<item>iOS</item>
<item>SCALA</item>
<item>Ruby</item>
<item>JavaScript</item>
</string-array>
将字符串res添加到搜索文本框:
searchView.setSuggestions(getResources().getStringArray(R.array.query_suggestions));
