android - 将数据发送到 Firebase 数据库后如何从片段移动到另一个片段?
问题描述
添加数据后有一个片段用于将数据发送到
我想要的firebase数据库并单击按钮发送到firebase,自动发送数据后将我发送到另一个片段
public class worker_add_fragment extends Fragment {
EditText phone, name;
Button addWorker;
@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.add_worker, container, false);
phone = view.findViewById(R.id.phone);
name = view.findViewById(R.id.name);
addWorker = view.findViewById(R.id.addBtn);
final FirebaseDatabase database = FirebaseDatabase.getInstance();
final DatabaseReference table_employee = database.getReference("Employees");
addWorker.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
final ProgressDialog dialog = new ProgressDialog(getActivity());
dialog.setMessage("انتظر!");
dialog.show();
if (name.length()==0){
dialog.dismiss();
name.setError("ادخل اسمك");
}else if (phone.length()==0){
dialog.dismiss();
phone.setError("ادحل رقم تليفونك");
}else{
table_employee.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot snapshot) {
//check if already phone exist
if (snapshot.child(phone.getText().toString()).exists()){
dialog.dismiss();
Toast.makeText(getActivity(), "انت مسجل من قبل", Toast.LENGTH_LONG).show();
}else{
dialog.dismiss();
Worker worker = new Worker(name.getText().toString());
table_employee.child(phone.getText().toString()).setValue(worker);
Toast.makeText(getActivity(), "تم التسجيل بنجاح", Toast.LENGTH_LONG).show();
//are the code that send me to another fragment write here?
getActivity().finish();
}
}
@Override
public void onCancelled(@NonNull DatabaseError error) { }
});
}
}
});
return view;
}
}

解决方案
您可以在您希望片段显示的 xml 文件中定义片段标记,如下所示:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<fragment
android:id="@+id/fragment_content_1"
android:name="com.example.fragmentexample.Fragment_1"
android:layout_width="0dip"
android:layout_weight="0.50"
android:layout_height="fill_parent" >
</fragment>
</LinearLayout>
然后你可以在你的主要活动中创建新功能,它膨胀片段意味着它在它的 xml 文件中
public void replaceFragment(Fragment fragment){
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.fragment_content_1,fragment)
.commit();
}
在您评论此行的地方调用此函数
//are the code that send me to another fragment write here?
