当我选择底部导航项并将其重定向到相应的片段时，我的项目中有五个片段。但问题是，当我更改片段时，工具栏正在刷新。我只想更改标题，工具栏的图像和背景色。我不想更改工具栏，它应该是相同的，只是我想更改标题、图像和背景色。请尝试下面的代码可能会对您有所帮助
ColorDrawable mColorDrawable = new ColorDrawable(Color.parseColor("#000000"));
getActivity().getActionBar().setBackgroundDrawable(mColorDrawable);
getActivity().getActionBar().setTitle("Alert");

共享您的java文件使用getActivity.setTitletitle；对于图像和背景，可以使用getActivity.setActionBarToolbar；如果我想把标题放在工具栏的中心，这意味着我必须要做的事情。是的，我可以设置背景色。问题是我想把标题放在工具栏的中心，然后我建议操作栏的其他地方，请在布局中使用工具栏。我会尝试使用工具栏
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbarM);
setSupportActionBar(toolbar);
