Question

我想通过电子邮件发送截图。以下是我如何设置截屏并保存在目录中。我想要的是不保存但直接发送。我怎样才能实现它？

public Bitmap takeScreenshot() {

    View rootView = getWindow().getDecorView().findViewById(R.id.relative);
    rootView.setDrawingCacheEnabled(true);

    return rootView.getDrawingCache();

}

public void saveBitmap(Bitmap bitmap) {

    String root = Environment.getExternalStorageDirectory().toString();
    File newDir = new File(root + "/MapCards");
    newDir.mkdirs();
    Random gen = new Random();
    int n = 10000;
    n = gen.nextInt(n);
    String fotoname = "MapCard-" + n + ".jpg";
    File file = new File(newDir, fotoname);
    if (file.exists())
        file.delete();
    try {
        FileOutputStream fos = new FileOutputStream(file);
        bitmap.compress(CompressFormat.JPEG, 100, fos);
        fos.flush();
        fos.close();
        Toast.makeText(getApplicationContext(),
                "Saved in folder: 'MapCards'", Toast.LENGTH_SHORT).show();

    } catch (FileNotFoundException e) {
        Log.e("GREC", e.getMessage(), e);
    } catch (IOException e) {
        Log.e("GREC", e.getMessage(), e);
    }

}

也许我需要添加类似下面的东西，在我拍摄截图后但我不确定如何配置它。

public void send() {
    String temp = getIntent().getStringExtra("picture_path");
    URI = Uri.parse("file://" + temp);
    final Intent emailIntent = new Intent(
            android.content.Intent.ACTION_SEND);
    emailIntent.setType("image/jpeg");
    if (URI != null) {
        emailIntent.putExtra(Intent.EXTRA_STREAM, URI);
    }
    this.startActivity(Intent.createChooser(emailIntent,
            "Send email using.."));

}

感谢您的帮助。

我的工作代码。请试试。

final File file = getTempPictureFile();
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setType(HTTP.PLAIN_TEXT_TYPE);
emailIntent.putExtra(Intent.EXTRA_SUBJECT, Constants.EMAIL_SUBJECT);
emailIntent.putExtra(Intent.EXTRA_TEXT, Html.fromHtml(Constants.EMAIL_BODY_MSG));
if(file != null)
{
     emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
}
startActivity(Intent.createChooser(emailIntent, Constants.CHOOSE_EMAIL_CLIENT));
