这是活动类的代码。
public class Form1Activity extends MainActivity {
private EditText factory_name,cell_no, _email:
private Spinner meter_type_spinner;
private Button form1submitbutton;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
factory_name = (EditText) findViewById(R.id.factorynameTF);
cell_no = (EditText) findViewById(R.id.cellnoTF);
_email = (EditText) findViewById(R.id.emailTF);
meter_type_spinner = (Spinner) findViewById(R.id.metertypedropdown);
form1submitbutton = (Button) findViewById((R.id.form1submitbtn));
List<String> metertype = new ArrayList<>();
metertype.add("day");
metertype.add("night");
ArrayAdapter<String> adpterMeterType = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, metertype);
adpterMeterType.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
meter_type_spinner.setAdapter(adpterMeterType);
}
以下是我调用活动的片段代码。知道请告诉我我做错了什么。我应该在片段中进行所有字段处理,还是为每个片段创建一个单独的活动来执行视图的工作,例如编辑tex,spinners等。
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.form1, container, false);
context = rootView.getContext();
Intent intent = new Intent(context, Form1Activity.class);
startActivity(intent);
return rootView;
}
答案 0 :(得分:0)
尝试:
Intent intent = new Intent(getActivity(), Form1Activity.class);
getActivity().startActivity(intent);
而不是
`Intent intent = new Intent(context, Form1Activity.class)`;
startActivity(intent);
