Question

我在我的应用上创建了一个“联系我们”页面，我们的想法是您可以选择将图片发送到已预先确定的电子邮件地址。我遇到的问题是从电话库中获取所有图像并将其全部发送到电子邮件中。我想做的就是发一张照片。我似乎无法确定要改变什么才能发送一个图像。有人可以提供帮助吗？

这是我的代码：

public class EmailActivity extends Activity {
        Button send;
        EditText address, subject, emailtext;
        protected static final int CAMERA_PIC_REQUEST = 0;



    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.email);
        send=(Button) findViewById(R.id.emailsendbutton);
        address=(EditText) findViewById(R.id.emailaddress);
        subject=(EditText) findViewById(R.id.emailsubject);
        emailtext=(EditText) findViewById(R.id.emailtext);

        send.setOnClickListener(new OnClickListener() {

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

                            if
                            (!Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState()))
                            {

                            }

                            File pngDir = new File(

                                    Environment.getExternalStorageDirectory(),
                                    "Android/data/com.random.jbrefurb/quote");

                            if (!pngDir.exists())
                                pngDir.mkdirs();

                            Uri pngUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;


                                     Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);


                                      emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{ "random@yahoo.co.uk"});

                                      emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject.getText());

                                      emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, emailtext.getText());

                                      emailIntent.putExtra(android.content.Intent.EXTRA_STREAM, pngUri);

                                      emailIntent.setType("image/jpeg");


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


                        }
                });

        Button back = (Button) findViewById(R.id.button1); 
        back.setOnClickListener(new View.OnClickListener() { 
            public void onClick(View view) {
                 // fire intent
                finish(); // finish current activity
                Intent austinIntent = new Intent(view.getContext(), 
                        ContactActivity.class); 
                startActivityForResult(austinIntent, 0);


            } 


        });




        Button camera = (Button) findViewById(R.id.button2); 
        camera.setOnClickListener(new View.OnClickListener() { 
            public void onClick(View view) {
                Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                  startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);  
;

                }     
            });  
        }  

    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {         
        if (requestCode== 0 && resultCode == Activity.RESULT_OK){                 
            Bitmap x = (Bitmap) data.getExtras().get("data");                 
            ((ImageView)findViewById(R.id.imageView1)).setImageBitmap(x);

            OutputStream outstream;                 
            try {
