我正在实施SearchView。我已成功添加搜索视图及其所有功能。现在我想让它看起来很棒。
我需要做两件事我尝试了所有事情,但没有任何对我有用:
这是我的searchView目前的样子:
这就是我想做的事情
菜单/ menu_search_action.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=".MainActivity">
<item
android:id="@+id/action_search"
android:icon="@drawable/location_icon"
android:orderInCategory="100"
android:title="@string/action_search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="always|collapseActionView" />
SearchCategoriesActivity.java
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_search_action, menu);
MenuItem searchItem = menu.findItem(R.id.action_search);
searchItem.expandActionView();
MenuItemCompat.setOnActionExpandListener(searchItem, new MenuItemCompat.OnActionExpandListener() {
@Override
public boolean onMenuItemActionExpand(MenuItem item) {
return true;
}
@Override
public boolean onMenuItemActionCollapse(MenuItem item) {
//DO SOMETHING WHEN THE SEARCHVIEW IS CLOSING
back();
return false;
}
});
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
searchView = (SearchView) MenuItemCompat
.getActionView(searchItem);
if (searchView != null) {
searchView.setSearchableInfo(searchManager
.getSearchableInfo(getComponentName()));
searchView.setIconifiedByDefault(false);
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String query) {
callSearch(query);
return true;
}
@Override
public boolean onQueryTextChange(String newText) {
callSearch(newText);
return true;
}
});
}
for (TextView textView : findChildrenByClass(searchView, TextView.class)) {
textView.setTextColor(Color.WHITE);
}
return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
back();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
@Override
public void onBackPressed() {
back();
}
private void back() {
finish();
}
public static <V extends View> Collection<V> findChildrenByClass(
ViewGroup viewGroup, Class<V> clazz) {
return gatherChildrenByClass(viewGroup, clazz, new ArrayList<V>());
}
private static <V extends View> Collection<V> gatherChildrenByClass(
ViewGroup viewGroup, Class<V> clazz, Collection<V> childrenFound) {
for (int i = 0; i < viewGroup.getChildCount(); i++) {
final View child = viewGroup.getChildAt(i);
if (clazz.isAssignableFrom(child.getClass())) {
childrenFound.add((V) child);
}
if (child instanceof ViewGroup) {
gatherChildrenByClass((ViewGroup) child, clazz, childrenFound);
}
}
return childrenFound;
}

如下所示添加单独的<style name="AppTheme.SearchView" parent="Widget.AppCompat.SearchView">
<item name="searchIcon">@mipmap/ic_search_white</item>
<item name="closeIcon">@mipmap/ic_clear_white</item>
</style>
以更改搜索图标。
Base Theme
在<!-- Base application theme. -->
<style name="MyMaterialTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="searchViewStyle">@style/AppTheme.SearchView</item>
</style>
return PostVote.aggregate([
{ "$match": { "post": { "$in": postIds } } },
{
"$group": {
"_id": "$post",
"votes": { "$sum": "$vote" },
"userVotes": {
"$sum": {
"$cond": [
{ "$eq": ["$user", userId] },
"$vote",
0
]
}
}
}
}
]).execAsync().then(function(votes){
return votes;
});

navigationBackButton和SearchView之间的多余空间可以通过添加来删除
app:contentInsetStartWithNavigation="0dp"
在您的工具栏中。
<androidx.appcompat.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:contentInsetStartWithNavigation="0dp" />

通过编程将MaxWidth设置为onCreateOptionsMenu()中的SearchView
@override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_search, menu);
SearchView searchView = (SearchView)menu.findItem(R.id.menu_search).getActionView();
searchView.setMaxWidth(Integer.MAX_VALUE);
针对使用Kotlin的人
searchview.maxWidth = Integer.MAX_VALUE
