Android: 使用已保存的导航抽屉从其他片段打开下一个片段
Android: Open next Fragment from other Fragment with saved Navigation Drawer
这是我的第一个问题，请多多包涵！ :D
我在我的应用程序导航抽屉中找到了一些位置，如下所示：
http://s16.postimg.org/7j9tglcn9/Quick_Memo_2015_05_18_22_18_43.png
一切都很好，我从 Navigation Drawer 中选择了 2 个元素，然后切换到 fragment，Navigation Drawer 的工作方式如下：
http://s10.postimg.org/44ehubiwp/Quick_Memo_2015_05_18_22_19_17.png
问题是，当我尝试通过此处的按钮从第一个片段 (1) 打开相同的片段时：
http://s17.postimg.org/4atca3133/Quick_Memo_2015_05_18_22_19_00.png
然后我转到下一个 Fragment，但导航抽屉不起作用。

来自第一个开关盒 0 的代码 - Testowa.java 带有按钮：
public class Testowa<T extends MainActivity> extends Fragment{
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final View view = inflater.inflate(R.layout.activity_testowa, container, false);
final Button button1=(Button) view.findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
FragmentTransaction ft = getActivity().getFragmentManager().beginTransaction();
Fragment mFragment = Fragment.instantiate(getActivity(), Dwukomorowe.class.getName());
ft.replace(android.R.id.content, mFragment);
ft.commit();
}
});
return view;
}
这里是 Fragment Dwukomorowe.java 中的最后一个代码 - 它是 Navigation Drawer 中的第二个元素 - 当我在 Teastowa.java 中单击按钮时相同的 Fragment:
public class Dwukomorowe extends Fragment implements View.OnClickListener {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.activity_dwukomorowe, container, false);
//setContentView(R.layout.activity_dwukomorowe);
this.setHasOptionsMenu(true);
return rootView;
}
您好！
我不明白你试图用你的按钮实现什么。
您要打开 Dwukomorowe 碎片吗？
您可以在您的 Activity 中创建一个方法并从您的片段中调用它。
public void loadDwukomorowe() {
getFragmentManager().beginTransaction()
.replace(R.id.frame_container, new Dwukomorowe())
.commit();
}
并从您的片段中调用它：
button1.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
((MainActivity) getActivity()).loadDwukomorowe();
}
});
