（求助） - 删除每个视图上的布局参数---

我是Android新手，我正在尝试从我在文本字段中输入的项目中添加TableLayout中的行。

（已编辑）以下是此片段的布局：

public static class ContactsFragment extends Fragment {
    @Override

        View rootView = inflater.inflate(R.layout.fragment_section_contacts,
                container, false);
        return rootView;
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);


        Spinner phoneTypeSpinner = (Spinner) this.getView().findViewById(R.id.contactPhoneTypeSpinner);
        Button contactButton = (Button) this.getView().findViewById(R.id.addContact);
        final TableLayout tableLayout = (TableLayout) this.getView().findViewById(R.id.contactsTableLayout);
        final EditText txtContactName = (EditText) this.getView().findViewById(R.id.contactName);
        final EditText txtContactRelationship = (EditText) this.getView().findViewById(R.id.contactRelationship);
        final EditText txtContactAddress = (EditText) this.getView().findViewById(R.id.contactAddress);
        final EditText txtContactPhoneNo = (EditText) this.getView().findViewById(R.id.contactPhoneNo);
        Spinner contactPhoneTypeSpinner = (Spinner) this.getView().findViewById(R.id.contactPhoneTypeSpinner);

        EmployeeDataSource datasource = new EmployeeDataSource(getActivity());
        datasource.open();

        //--- Gender Spinner ---
        List<PhoneType> list = datasource.getPhoneTypeList();
        ArrayAdapter<PhoneType> adapter = new ArrayAdapter<PhoneType>(getActivity(),
                android.R.layout.simple_spinner_item, list);
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        phoneTypeSpinner.setAdapter(adapter);

        phoneTypeSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

            }

            public void onNothingSelected(AdapterView<?> parent) {
            }
        });

        contactButton.setOnClickListener(new View.OnClickListener() {
            int rowId = 0;
            @Override
            public void onClick(View v) {

                TableRow tableRow = new TableRow(getActivity().getApplicationContext());
                tableRow.setId(rowId++);
                tableRow.setLayoutParams(new ViewGroup.LayoutParams(
                        ViewGroup.LayoutParams.FILL_PARENT,
                        ViewGroup.LayoutParams.WRAP_CONTENT));

                TextView tvContactName = new TextView(getActivity().getApplicationContext());
                tvContactName.setText(txtContactName.getText().toString());
                tvContactName.setLayoutParams(new ViewGroup.LayoutParams(
                        ViewGroup.LayoutParams.FILL_PARENT,
                        ViewGroup.LayoutParams.WRAP_CONTENT));
                tableRow.addView(tvContactName);

                TextView tvRelationship = new TextView(getActivity().getApplicationContext());
                tvRelationship.setText(txtContactRelationship.getText().toString());
                //tvRelationship.setLayoutParams(new ViewGroup.LayoutParams(
                //        ViewGroup.LayoutParams.FILL_PARENT,
                //        ViewGroup.LayoutParams.WRAP_CONTENT));
                tableRow.addView(tvRelationship);

                TextView tvContactNo = new TextView(getActivity().getApplicationContext());
                tvContactNo.setText(txtContactPhoneNo.getText().toString());
                //tvContactNo.setLayoutParams(new ViewGroup.LayoutParams(
                //        ViewGroup.LayoutParams.FILL_PARENT,
                //        ViewGroup.LayoutParams.WRAP_CONTENT));
                tableRow.addView(tvContactNo);

                tableLayout.addView(tableRow, new TableLayout.LayoutParams(
                        ViewGroup.LayoutParams.FILL_PARENT,
                        ViewGroup.LayoutParams.WRAP_CONTENT));
            }
        });
    }
}

我可以在调试器中看到我的视图中的值已添加到我的tableRow中但是我没有看到该表出现在我的屏幕中，我错过了什么或做错了什么？

非常感谢任何帮助。

谢谢！

Answer 1

我猜屏幕的高度增加了。尝试在此布局的顶部使用Scrollview。

Answer 2

我认为您必须更改RelativeLayout属性android:height="wrap_content"而非android:height="fill_parent"，同时更改为TableLayout

愿这对你有用......

试试这个：的编辑：

public static class ContactsFragment extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment_section_contacts, container, false); Spinner phoneTypeSpinner = (Spinner) rootView.findViewById(R.id.contactPhoneTypeSpinner); Button contactButton = (Button) rootView.findViewById(R.id.addContact); final TableLayout tableLayout = (TableLayout) rootView.findViewById(R.id.contactsTableLayout); final EditText txtContactName = (EditText) rootView.findViewById(R.id.contactName); final EditText txtContactRelationship = (EditText) rootView.findViewById(R.id.contactRelationship); final EditText txtContactAddress = (EditText) rootView.findViewById(R.id.contactAddress); final EditText txtContactPhoneNo = (EditText) rootView.findViewById(R.id.contactPhoneNo); Spinner contactPhoneTypeSpinner = (Spinner) rootView.findViewById(R.id.contactPhoneTypeSpinner); EmployeeDataSource datasource = new EmployeeDataSource(getActivity()); datasource.open(); //--- Gender Spinner --- List<PhoneType> list = datasource.getPhoneTypeList(); ArrayAdapter<PhoneType> adapter = new ArrayAdapter<PhoneType>(getActivity(), android.R.layout.simple_spinner_item, list); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); phoneTypeSpinner.setAdapter(adapter); phoneTypeSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() { public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { } public void onNothingSelected(AdapterView<?> parent) { } }); contactButton.setOnClickListener(new View.OnClickListener() { int rowId = 0; @Override public void onClick(View v) { TableRow tableRow = new TableRow(getActivity().getApplicationContext()); tableRow.setId(rowId++); TextView tvContactName = new TextView(getActivity().getApplicationContext()); tvContactName.setText(txtContactName.getText().toString()); tableRow.addView(tvContactName); TextView tvRelationship = new TextView(getActivity().getApplicationContext()); tvRelationship.setText(txtContactRelationship.getText().toString()); tableRow.addView(tvRelationship); TextView tvContactNo = new TextView(getActivity().getApplicationContext()); tvContactNo.setText(txtContactPhoneNo.getText().toString()); tableRow.addView(tvContactNo); tableLayout.addView(tableRow, new TableLayout.LayoutParams( ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)); } }); return rootView; } @Override public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); } }

如何在Android中的EditTexts中添加表格中的项目？
