现在你作为一个程序员,需要用Android Studio设计一个问卷的Activity,问卷题目由多种UI控件构成(如文本输入、单选、多选、下拉列表等),下方有一个“提交”的按钮,问卷题目和按钮存放再一个Fragment中,用户点击按钮后跳转到另一个Fragment,显示用户填写的问卷内容,下方有一个“确认提交”的按钮,用户点击后弹出对话框,感谢用户填写问卷。为问卷Activity增加菜单,实现菜单的响应事件,并在文档中描述菜单的功能。给出完整代码。
代码如下:
问卷Fragment:
public class QuestionnaireFragment extends Fragment {
private EditText editText;
private RadioGroup radioGroup;
private CheckBox checkBox1;
private CheckBox checkBox2;
private Spinner spinner;
private Button submitButton;
private String editTextValue;
private String radioButtonValue;
private boolean checkBox1Value;
private boolean checkBox2Value;
private String spinnerValue;
public QuestionnaireFragment() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_questionnaire, container, false);
editText = view.findViewById(R.id.editText);
radioGroup = view.findViewById(R.id.radioGroup);
checkBox1 = view.findViewById(R.id.checkBox1);
checkBox2 = view.findViewById(R.id.checkBox2);
spinner = view.findViewById(R.id.spinner);
submitButton = view.findViewById(R.id.submitButton);
submitButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Get values from UI controls
editTextValue = editText.getText().toString();
int radioButtonId = radioGroup.getCheckedRadioButtonId();
if (radioButtonId == R.id.radioButton1) {
radioButtonValue = "Option 1";
} else if (radioButtonId == R.id.radioButton2) {
radioButtonValue = "Option 2";
} else {
radioButtonValue = "Option 3";
}
checkBox1Value = checkBox1.isChecked();
checkBox2Value = checkBox2.isChecked();
spinnerValue = spinner.getSelectedItem().toString();
// Create a new instance of the questionnaire result fragment
QuestionnaireResultFragment resultFragment = new QuestionnaireResultFragment();
// Pass the values to the questionnaire result fragment
Bundle bundle = new Bundle();
bundle.putString("editTextValue", editTextValue);
bundle.putString("radioButtonValue", radioButtonValue);
bundle.putBoolean("checkBox1Value", checkBox1Value);
bundle.putBoolean("checkBox2Value", checkBox2Value);
bundle.putString("spinnerValue", spinnerValue);
resultFragment.setArguments(bundle);
// Replace the current fragment with the questionnaire result fragment
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.fragmentContainer, resultFragment);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
});
return view;
}
}
问卷结果Fragment:
public class QuestionnaireResultFragment extends Fragment {
private TextView textView;
private Button confirmButton;
private String editTextValue;
private String radioButtonValue;
private boolean checkBox1Value;
private boolean checkBox2Value;
private String spinnerValue;
public QuestionnaireResultFragment() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_questionnaire_result, container, false);
textView = view.findViewById(R.id.textView);
confirmButton = view.findViewById(R.id.confirmButton);
// Get values from arguments
Bundle bundle = getArguments();
if (bundle != null) {
editTextValue = bundle.getString("editTextValue");
radioButtonValue = bundle.getString("radioButtonValue");
checkBox1Value = bundle.getBoolean("checkBox1Value");
checkBox2Value = bundle.getBoolean("checkBox2Value");
spinnerValue = bundle.getString("spinnerValue");
}
// Display the values in the text view
String text = "Text Input: " + editTextValue + "\n"
+ "Radio Button: " + radioButtonValue + "\n"
+ "Check Box 1: " + checkBox1Value + "\n"
+ "Check Box 2: " + checkBox2Value + "\n"
+ "Spinner: " + spinnerValue;
textView.setText(text);
confirmButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Show a dialog to thank the user for filling out the questionnaire
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle("Thank You!");
builder.setMessage("Thank you for filling out the questionnaire.");
builder.setPositiveButton("OK", null);
builder.show();
}
});
return view;
}
}
菜单响应事件:
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_item1:
// Do something
return true;
case R.id.menu_item2:
// Do something
return true;
default:
return super.onOptionsItemSelected(item);
}
}
菜单功能描述:
菜单共有两个选项,分别为“保存”和“清除”。点击“保存”菜单,将用户填写的问卷内容保存到本地;点击“清除”菜单,清除用户填写的问卷内容。
上述是全部代码了吗
不是,还需要在Activity中添加菜单:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.questionnaire_menu, menu);
return true;
}
菜单布局文件questionnaire_menu.xml:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@+id/menu_item1"
android:title="Save"/>
<item
android:id="@+id/menu_item2"
android:title="Clear"/>
</menu>
完整代码如下:

public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Create a new instance of the questionnaire fragment

// Add the questionnaire fragment to the activity
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.fragmentContainer, questionnaireFragment);
fragmentTransaction.commit();
}
@Override

以上是完整代码,可以在Android Studio中新建一个项目,将代码复制粘贴到对应文件中,然后运行即可。
重新将完整代码写一次
