我正在制作一个应用程序，该应用程序现在将使用您对几个问题的回答来创建一封带有仇恨信息的电子邮件。我想知道如何添加一个功能，让我可以拍照然后通过电子邮件将其发送给那个人，我相信我已经正确设置了一些东西，但我不知道如何通过电子邮件发送它。我的代码如下。我还可以提供我尚未添加的任何其他信息

package com.example.first_app;

import java.io.IOException;
import java.io.InputStream;

import android.app.Activity;
import android.app.WallpaperManager;
import android.content.DialogInterface.OnClickListener;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageView;

public class Email extends Activity implements View.OnClickListener{

EditText personsEmail, intro, personsName, stupidThings, hatefulAction,
        outro;
String emailAdd, beginning, name, stupidAction, hatefulAct, out;
Button sendEmail;
Button takePicture;
ImageView Picture;
final static int Camera_data = 0;
Bitmap bmp;
Intent i;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.email);
    initializeVars();
    sendEmail.setOnClickListener(this);
    takePicture.setOnClickListener(this);
    InputStream is = getResources().openRawResource(R.drawable.ic_launcher);
    bmp = BitmapFactory.decodeStream(is);
}

private void initializeVars() {
    // TODO Auto-generated method stub
    personsEmail = (EditText) findViewById(R.id.etEmails);
    intro = (EditText) findViewById(R.id.etIntro);
    personsName = (EditText) findViewById(R.id.etName);
    stupidThings = (EditText) findViewById(R.id.etThings);
    hatefulAction = (EditText) findViewById(R.id.etAction);
    outro = (EditText) findViewById(R.id.etOutro);
    sendEmail = (Button) findViewById(R.id.bSentEmail);
    takePicture = (Button) findViewById(R.id.take_Picture);
    Picture = (ImageView) findViewById(R.id.iv_Returned_Picture);
}

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

    convertEditTextVarsIntoStringsAndYesThisIsAMethodWeCreated();
    String emailaddress[] = { emailAdd };
    String message = "Well hello "
            + name
            + " I just wanted to say "
            + beginning
            + ".  Not only that but I hate when you "
            + stupidAction
            + ", that just really makes me crazy.  I just want to make you "
            + hatefulAct
            + ".  Welp, thats all I wanted to chit-chatter about, oh and"
            + out
            + '\n' + "PS. I think I love you...    ";



    Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
    emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, emailaddress);
    emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "I hate you");
    emailIntent.setType("plain/text");
    emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, message);
    startActivity(emailIntent);

}

private void convertEditTextVarsIntoStringsAndYesThisIsAMethodWeCreated() {
    // TODO Auto-generated method stub
    emailAdd = personsEmail.getText().toString();
    beginning = intro.getText().toString();
    name = personsName.getText().toString();
    stupidAction = stupidThings.getText().toString();
    hatefulAct = hatefulAction.getText().toString();
    out = outro.getText().toString();
}

@Override
protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
    finish();
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK){
        Bundle extras = data.getExtras();
        bmp = (Bitmap) extras.get("data");
        Picture.setImageBitmap(bmp);
}
}
}

这将显示可用于发送电子邮件的电子邮件客户端列表。你可以通过启动一个 Intent 让 Android 为你处理邮件：

final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND_MULTIPLE); //allow multiple attachments

emailIntent.setType("plain/text"); //limits how Android handles the "send" request to email rather than Facebook, Peep, etc.
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, getText(R.string.subject)); //set the email subject line

ArrayList<Uri> uris = new ArrayList<Uri>(); //multiple attachments must be added via list object
File root = Environment.getExternalStorageDirectory(); //root filepath

//get images to add to email
File fileIn = new File(root, "image.png");
Uri u = Uri.fromFile(fileIn);
uris.add(u);

//get another image to add to email
fileIn = new File(root, "image2.jpg");
u = Uri.fromFile(fileIn);
uris.add(u);
//add images to email
emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);

AdminActivity.this.startActivity(Intent.createChooser(emailIntent, "Send mail..."));

您还可以查看Android 相机意图以了解如何启动相机意图并使用它返回的图像 uri 执行某些操作。
