如何在Android应用程序中使用编辑文本计算年龄

<EditText
    android:id="@+id/editTextDateOfBirth"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="请输入出生日期"
    android:inputType="date" />

EditText editTextDateOfBirth = findViewById(R.id.editTextDateOfBirth);
String dateString = editTextDateOfBirth.getText().toString();

// 根据用户输入的日期字符串创建日期对象
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd", Locale.getDefault());
Date dateOfBirth = sdf.parse(dateString);

// 获取当前日期
Date currentDate = new Date();

// 计算年龄
Calendar dob = Calendar.getInstance();
dob.setTime(dateOfBirth);
Calendar now = Calendar.getInstance();
int age = now.get(Calendar.YEAR) - dob.get(Calendar.YEAR);
if (now.get(Calendar.DAY_OF_YEAR) < dob.get(Calendar.DAY_OF_YEAR)) {
    age--;
}

Toast.makeText(getApplicationContext(), "年龄为：" + age, Toast.LENGTH_SHORT).show();
