如何在Android上创建电子邮件按钮？

    android:id="@+id/email_button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="发送电子邮件"
    android:layout_centerInParent="true" />

Button emailButton = findViewById(R.id.email_button);
emailButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // 在这里处理按钮点击事件
    }
});

Intent emailIntent = new Intent(Intent.ACTION_SENDTO);
emailIntent.setData(Uri.parse("mailto:"));
emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{"recipient@example.com"});
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "邮件主题");
emailIntent.putExtra(Intent.EXTRA_TEXT, "邮件正文");

if (emailIntent.resolveActivity(getPackageManager()) != null) {
    startActivity(emailIntent);
} else {
    Toast.makeText(this, "没有找到可用的应用程序来发送邮件", Toast.LENGTH_SHORT).show();
}
