Question

我在点击Button时尝试发送电子邮件，我想在发送电子邮件后转到应用的主页。我尝试了这段代码，但它没有用。我可以发送电子邮件，但之后我无法访问主页，我将转到发送电子邮件的同一页面。

public void onSendClick(View view) {
Intent intent = new Intent(Intent.ACTION_SEND_MULTIPLE);
    intent.setType("Audio/mp3");
    intent.putExtra(Intent.EXTRA_SUBJECT, "Attachment from app");
    intent.putExtra(Intent.EXTRA_TEXT, "Sending mp3 file ");

    intent.putExtra(Intent.EXTRA_EMAIL, new String[] {"email@example.com"});
    ArrayList<Uri> uris = new ArrayList<Uri>();

    uris.add(Uri.fromFile(new File(mFileName.getAbsolutePath())));

    intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);

    startActivity(Intent.createChooser(intent, "Send mail"));

  /* Intent i = new Intent(SubmitActivity.this, MainActivity.class);
    //i.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
    this.startActivity(i); */
}

Answer 1

尝试使用startActivityForResult方法并导航到onActivityResult回调中的主页。在销毁电子邮件活动后调用onActivtyResult回调。

    static final int EMAIL_REQUEST = 1;

    public void onSendClick(View view) {
        Intent intent = new Intent(Intent.ACTION_SEND_MULTIPLE);
        intent.setType("Audio/mp3");
        intent.putExtra(Intent.EXTRA_SUBJECT, "Attachment from app");
        intent.putExtra(Intent.EXTRA_TEXT, "Sending mp3 file ");

        intent.putExtra(Intent.EXTRA_EMAIL, new String[] {"xxx@yahoo.co.uk"});
        ArrayList<Uri> uris = new ArrayList<Uri>();

        uris.add(Uri.fromFile(new File(mFileName.getAbsolutePath())));

        intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
        startActivityForResult(Intent.createChooser(intent, "Send mail"), EMAIL_REQUEST);
    }

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if(requestCode == EMAIL_REQUEST) {
            //Navigate to home page from here.
        }
    }

如果您参与了主页活动中调用的活动，请尝试

startActivity(..);
finish();

如何在一个按钮内单击使用两个意图？
