我希望菜单中的标题会因点击的片段名称而改变。我得到的代码是,每个片段中的实际标题是“Home”,它不会改变。但我发现,当我点击菜单中的一个项目时,标题会改变一秒并返回“主页”标题。我实施了拉杆机,但我仍然不知道是什么原因造成的。

为所有片段设置它。这应该做的工作!!
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.id.your_fragment_layout, container,
false);
getActivity().setTitle("<your title>");
return rootView;
}

试试这个:
SELECT * FROM (
SELECT id_product, picture_url, product_name, product_price, tracking_link, '$ecommerce2->nama_ecommerce' AS table_identity FROM table1 WHERE product_name LIKE '%$search%'
UNION ALL
SELECT id_product, picture_url, product_name, product_price, tracking_link, '$ecommerce2->nama_ecommerce' AS table_identity FROM table2 WHERE product_name LIKE '%$search%'
) AS big_table1 ORDER BY product_price LIMIT 1
UNION
SELECT * FROM (
SELECT id_product, picture_url, product_name, product_price, tracking_link, '$ecommerce2->nama_ecommerce' AS table_identity FROM table1 WHERE product_name LIKE '%$search%'
UNION ALL
SELECT id_product, picture_url, product_name, product_price, tracking_link, '$ecommerce2->nama_ecommerce' AS table_identity FROM table2 WHERE product_name LIKE '%$search%'
) AS big_table2 ORDER BY product_price DESC LIMIT 1

好的,我发现了问题,你的答案很好,我每次都从片段中更改标题,但另外我需要禁用此行:
getSupportActionBar().setTitle(mDrawerTitle);
来自onDrawerOpened和onDrawerClosed
答案 3 :(得分:2)
不要将标题设置为ActionBar,将标题设置为Activity,您可以通过activity或fragment执行此操作。 对于活动:
setTitle("New Title");
或片段:
getActivity().setTitle("New Title");
答案 4 :(得分:0)
在片段
中添加此内容getActivity().setTitle("title");
添加从抽屉活动
中移除此行getActivity().setTitle("title");
答案 5 :(得分:0)
尝试这个对我有用的
在app_bar活动的工具栏中放置一个Textview
在片段的oncreateView内放置此代码
TextView heading;
heading=(TextView)getActivity().findViewById(R.id.Id_title);
heading.setText("your text");
使用此功能,您可以使用自己的文本命名每个片段

在onCreateView()中编写以下代码:
//Sidebar Filter Genre Tracks
$(document).ready(function () {
$('.genreTag').on('change', function (e)
{
$('input.filter-playlist, .popularGenreTag, .mood-emotion, .production-type, .vocals, .all-tracks, .last-year, .last-month, .last-week, .last-day').each(function() {
var $this = $(this);
$this.prop('checked', false);
$this.parent().find('> div').removeClass('chk-checked').addClass('chk-unchecked');
});
e.preventDefault();
id = [];
$('.genreTag:checked').each(function()
{
id.push($(this).attr('id'));
});
$.get("/genre-tags/", {id: id}, function(data)
{
hideLoader();
refreshedPage = $(data);
newDemo = refreshedPage.find(".libraryWrapper, .albumWrapper, .composersWrapper, .albumsListWrapper, .albumsWrapper, .accountWrapper, .distributionsWrapper, .PaymentsWrapper, .contactWrapper, .contractsWrapper, .toolsWrapper, .blogWrapper, .pageWrapper, .cartWrapper, .pageWrapper").html();
$('.libraryWrapper, .albumsWrapper, .albumWrapper, .composersWrapper, .albumsListWrapper, .accountWrapper, .distributionsWrapper, .PaymentsWrapper, .contactWrapper, .contractsWrapper, .toolsWrapper, .blogWrapper, .pageWrapper, .cartWrapper, .pageWrapper').html(newDemo);
activatePlayer()
initTrackInfo();
});
});
});
//route
Route::get('genre-tags/', ['as' => 'tag.popular-genres', 'uses' => 'SideFilterController@genresFilter']);
//checkbox blade file
<li class="lib">
<label><input class="genreTag" id="{{ $genreTag->id}}" type="checkbox" name="" value="{{ $genreTag->name }}">{{{ $genreTag->name }}} ({{count(json_decode($genreTag->elements, true))+ count(json_decode($genreTag->tracks, true))}}) </label>
</li>
