Android调查问卷代码

以下是一个简单的 Android 调查问卷代码，供参考：

布局文件 activity_main.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <TextView
        android:id="@+id/questionTextView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="问题 1：你喜欢 Android 吗？" />

    <RadioGroup
        android:id="@+id/answerRadioGroup"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">

        <RadioButton
            android:id="@+id/answerYesRadioButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="喜欢" />

        <RadioButton
            android:id="@+id/answerNoRadioButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="不喜欢" />

        <RadioButton
            android:id="@+id/answerNeutralRadioButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="不确定" />
    </RadioGroup>

    <Button
        android:id="@+id/submitButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="提交" />

</LinearLayout>

Java 代码 MainActivity.java：

import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.TextView;
import android.widget.Toast;

import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    private TextView questionTextView;
    private RadioGroup answerRadioGroup;
    private RadioButton answerYesRadioButton;
    private RadioButton answerNoRadioButton;
    private RadioButton answerNeutralRadioButton;
    private Button submitButton;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        questionTextView = findViewById(R.id.questionTextView);
        answerRadioGroup = findViewById(R.id.answerRadioGroup);
        answerYesRadioButton = findViewById(R.id.answerYesRadioButton);
        answerNoRadioButton = findViewById(R.id.answerNoRadioButton);
        answerNeutralRadioButton = findViewById(R.id.answerNeutralRadioButton);
        submitButton = findViewById(R.id.submitButton);

        submitButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                int checkedRadioButtonId = answerRadioGroup.getCheckedRadioButtonId();
                if (checkedRadioButtonId == -1) {
                    Toast.makeText(MainActivity.this, "请选择一个选项！", Toast.LENGTH_SHORT).show();
                } else {
                    RadioButton checkedRadioButton = findViewById(checkedRadioButtonId);
                    String answerText = checkedRadioButton.getText().toString();
                    Toast.makeText(MainActivity.this, "你选择了：" + answerText, Toast.LENGTH_SHORT).show();
                }
            }
        });
    }
}

这段代码中，我们使用了一个 RadioGroup 来显示问题的选项，并在点击提交按钮时获取用户选择的选项，并用 Toast 显示在屏幕上。当然，这只是一个简单的示例，实际的调查问卷可能会更加复杂。
