my java code for calling email client

  btn1 = (Button) findViewById(R.id.button5) ;
        btn1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String phno="email";

                Intent intent = new Intent(Intent.ACTION_VIEW);
                Uri data = Uri.parse("mailto:" +phno);

            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:text="E-MAIL"

            android:layout_weight="1"
            android:background="#EFEFEF"/>

I think this would help you

Intent in = new Intent(Intent.ACTION_SEND);
in.setType("plain/text");
in.putExtra(Intent.EXTRA_EMAIL, new String[] { "mail id" });
in.putExtra(Intent.EXTRA_SUBJECT, "subject");
in.putExtra(Intent.EXTRA_TEXT, "mail body");
startActivity(Intent.createChooser(in, ""));

回答2:

Try this

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"));

Try following

    private void sendEmail(File file){
            Intent emailIntent = new Intent(Intent.ACTION_SEND);
            emailIntent.setType("text/html");
            final PackageManager pm = this.getPackageManager();
            final List<ResolveInfo> matches = pm.queryIntentActivities(emailIntent, 0);
            String className = null;
            for (final ResolveInfo info : matches) {
                if (info.activityInfo.packageName.equals("com.google.android.gm")) {
                    className = info.activityInfo.name;

                    if(className != null && !className.isEmpty()){
                        break;
                    }
                }
            }
            emailIntent.setClassName("com.google.android.gm", className);
            emailIntent.setType("vnd.android.cursor.dir/email");
            emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
            emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{"[e-mail]"});
            emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
            emailIntent.setType("plain/text");
            startActivity(emailIntent);

        }
