java - 尝试将 EditText 表单提交到我的电子邮件时出错？没有应用程序可以执行此操作？

Question

这是错误消息...

"Class 'Anonymous class derived from OnClickListener' must either be declared abstract or implement abstract method 'onClick(View)' in 'OnClickListener'"

这是源代码，有人知道如何修复此错误吗？

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

    Button donationButton = (Button) findViewById(R.id.donation_submit_button);
    donationButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            startActivity(new Intent(DonateActivity.this, PostDonationActivity.class));
        }
    });


    donationButton.setOnClickListener(new View.OnClickListener() {
        public void onClick() {
            Intent i = new Intent(Intent.ACTION_SEND);
            i.setType("message/rfc822");
            i.putExtra(Intent.EXTRA_EMAIL, new String[]{
                    "ethan.reinsch@fillmorecentral.org"
            });
            i.putExtra(Intent.EXTRA_SUBJECT, "Test Subject");
            i.putExtra(Intent.EXTRA_TEXT, "Test Body");
            try {
                startActivity(Intent.createChooser(i, "Send mail..."));
            } catch (android.content.ActivityNotFoundException ex) {
                Toast.makeText(DonateActivity.this, "There are no email clients installed.",
                        Toast.LENGTH_SHORT).show();
            }
        }
    });

非常感谢所有帮助!我对 Android Studio 和一般的 Android 应用程序开发相当陌生。谢谢!

更新/编辑:我让它工作，但是当我单击“提交”时，它说没有应用程序可以执行此操作？我正在使用模拟器。在实际设备上会有所不同吗？谢谢!

donationButton.setOnClickListener(new View.OnClickListener() {
       // here is problem
        @Override
        public void onClick(View view) {
            Intent i = new Intent(Intent.ACTION_SEND);
            i.setType("message/rfc822");
            i.putExtra(Intent.EXTRA_EMAIL, new String[]{
                    "ethan.reinsch@fillmorecentral.org"
            });
            i.putExtra(Intent.EXTRA_SUBJECT, "Test Subject");
            i.putExtra(Intent.EXTRA_TEXT, "Test Body");
            try {
                startActivity(Intent.createChooser(i, "Send mail..."));
            } catch (android.content.ActivityNotFoundException ex) {
                Toast.makeText(DonateActivity.this, "There are no email clients installed.",
                        Toast.LENGTH_SHORT).show();
            }
        }
    });
