代码：

Intent messageIntent = new Intent(android.content.Intent.ACTION_SEND);
String aEmailList[] = { "rakesh@rocketmail.com" };   
messageIntent.putExtra(android.content.Intent.EXTRA_EMAIL, aEmailList);
messageIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);
messageIntent.setType("text/html");
messageIntent.putExtra(android.content.Intent.EXTRA_TEXT, Html.fromHtml(body.toString()));
startActivity(messageIntent);

最后在SahilMahajanMj的帮助下，我使用了这段代码几乎没有变化：

 Intent i = new Intent(Intent.ACTION_SEND);
 i.putExtra(Intent.EXTRA_EMAIL  , new String[]{"rakesh@rocketmail.com"});
 i.putExtra(Intent.EXTRA_SUBJECT, subject);
 i.setType("message/rfc822");
 i.putExtra(Intent.EXTRA_TEXT, Html.fromHtml(body.toString()));

try {
    startActivity(Intent.createChooser(i, "Send email via :"));
    Toast.makeText(ArrowsActivity.this, "Email Sent.", Toast.LENGTH_SHORT).show();
} catch (android.content.ActivityNotFoundException ex) {
    Toast.makeText(ArrowsActivity.this, "There are no email applications installed.", Toast.LENGTH_SHORT).show();
}

在 ViewCartActivity.java

中

public void onClick(View v) {
    // TODO Auto-generated method stub

        Intent mViewCartIntent = new Intent(ViewCartActivity.this, com.version.bajrang.january.menu.ArrowsActivity.class);
        mViewCartIntent.putExtra("name", myTextVeiwGrandTotal.getText().toString());
        startActivity(mViewCartIntent);

            }
        });

在 ArrowsActivity.java中：

TextView txtName = (TextView) findViewById(R.id.total);
Intent i = getIntent();
String name = i.getStringExtra("name");
txtName.setText(name);

我使用上面的代码来获取购物车中的产品总数，我也可以获得并显示，但是这里购物车中的商品总数我也希望在购物车标签上显示如下：

https://play.google.com/store/apps/details?id=com.queppelin.tastykhana

他们用红色表示2 ......

Answer 1

错误消息显示：

ActivityNotFoundException：找不到处理Intent的Activity { act = android.intent.action.SEND typ = text / html flg = 0x1（has clip）（有额外的）}

这意味着android系统没有找到任何电子邮件发送活动来处理您创建的意图。确保您的设备中安装了电子邮件应用程序。

还可以使用以下代码发送电子邮件，

Intent i = new Intent(Intent.ACTION_SEND);
i.setType("message/rfc822");
i.putExtra(Intent.EXTRA_EMAIL  , new String[]{"recipient@example.com"});
i.putExtra(Intent.EXTRA_SUBJECT, "subject of email");
i.putExtra(Intent.EXTRA_TEXT   , "body of email");
try {
    startActivity(Intent.createChooser(i, "Send mail"));
} catch (android.content.ActivityNotFoundException ex) {
    Toast.makeText(MyActivity.this, "There are no email applications installed.", Toast.LENGTH_SHORT).show();
}

Rakesh抱歉迟到的回复，因为上午10点我试图解决你的问题，我已经尝试了几次，最后下面的代码工作：

我知道你得到了答案，但我已经花了很多时间让我满意，我在这里提出答案，兄弟我不需要积分，因为@SahilMahajanMj值得这样：

  Intent i = new Intent(Intent.ACTION_SEND);
        i.putExtra(Intent.EXTRA_EMAIL  , new String[]{"rakesh@rocketmail.com"});
        i.putExtra(Intent.EXTRA_SUBJECT, subject);
        i.setType("message/rfc822");
        i.putExtra(Intent.EXTRA_TEXT, Html.fromHtml(body.toString()));

        try {
            startActivity(Intent.createChooser(i, "Send email via :"));
            } catch (android.content.ActivityNotFoundException ex) {
            Toast.makeText(ArrowsActivity.this, "There are no email applications installed.", Toast.LENGTH_SHORT).show();
        }

Answer 3

您使用android.content传递putExtras的问题。

尝试以下内容：

public Intent sendMail1() {
        Intent messageIntent = new Intent(Intent.ACTION_SEND);

        String aEmailList[] = { "rakesh@rocketmail.com" };
        messageIntent.putExtra(Intent.EXTRA_EMAIL, aEmailList);

        messageIntent.putExtra(Intent.EXTRA_SUBJECT, subject);

        messageIntent.setType("text/html");
        messageIntent.putExtra(Intent.EXTRA_TEXT,
                Html.fromHtml(body.toString()));

        return messageIntent;
    }

点燃你的意图：

startActivity(Intent.createChooser(sendMail1(), "send mail"));
