            startActivity(emailIntent); // <-- AND HERE

        }finally {

        }

    }

Answer 1

您设置点击监听器的方式有误。

实现 ClickListener

public class SingleItemView extends AppCompatActivity implements View.OnClickListener
设置监听器 sendEmail.setOnClickListener(this);
使用注释

@Override public void onClick(View v)

请试试看。

Answer 2

试试这个：

sendEmail.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            if(view.getId()==R.id.button5){
                Intent i = new Intent(Intent.ACTION_SEND);
                i.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{ emailAddress });
                i.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);
                i.putExtra(android.content.Intent.EXTRA_TEXT, text);
                startActivity(Intent.createChooser(i, "Send email"));
            }

        }
    });

我可能没有正确理解你的问题，我建议你使用以下插件https://github.com/katzer/cordova-plugin-email-composer#examples。基本上，使用此插件，您只需单击一个按钮即可发送 HTML 嵌入的正文。

cordova.plugins.email.open({
to:      'max@mustermann.de',
subject: 'Greetings',
body:    '<h1>Nice greetings from Leipzig</h1>',
isHtml:  true
});

请查看文档以获取更多信息。希望对你有帮助。
