问题描述

我有一个应用程序，拍照并存储在内部的图片，我已经创建了一个文件夹中。在拍摄照片后，我希望能够访问它，这样我可以通过电子邮件发送。我如何才能访问我刚才拍摄的图像下面是我的code，节省了图像拍摄完毕后，在内部图像：

 保护无效的onActivityResult（INT申请code，INT结果code，意图数据）{
    super.onActivityResult（要求code，结果code，数据）;
    如果（结果code == RESULT_OK）{
        捆绑额外= data.getExtras（）;
        BMP =（位图）extras.get（数据）;
        iv.setImageBitmap（BMP）;        文件storagePath =新的文件（
                Environment.getExternalStorageDirectory（）+/ DavePics /）;
        storagePath.mkdirs（）;        文件MYIMAGE =新的文件（storagePath，Long.toString（系统
                .currentTimeMillis（））+.JPG）;
        位图B = Bitmap.createScaledBitmap（BMP，320，480，FALSE）;        尝试{
            FileOutputStream中出=新的FileOutputStream（MYIMAGE）;
            b.com preSS（Bitmap.Com pressFormat.JPEG，80出）;
            了out.flush（）;
            out.close（）;
        }赶上（例外五）{
            e.printStackTrace（）;
        }    }
}}

当我检查我已创建的文件夹的图片是存在的。我想现在要做的就是访问该图片，这样我可以在一封电子邮件从下我的code发送：

  @覆盖
公共无效的onClick（视图v）{    // TODO自动生成方法存根
    开关（v.getId（））{
    案例R.id.bSendPic：        串EMAILADDRESS [] = {info@sklep.com，，};        意图emailIntent =新意图（Intent.ACTION_SEND）;
        emailIntent.putExtra（Intent.EXTRA_EMAIL，EMAILADDRESS）;        //emailIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT，PIC）;        emailIntent.setType（图像/ JPEG）;
        startActivity（Intent.createChooser（emailIntent，发送邮件））;        打破;
    案例R.id.ibTakePic：        I =新意图（android.provider.MediaStore.ACTION_IM​​AGE_CAPTURE）;        startActivityForResult（ⅰ，cameraData）;
        打破;
    }}

我如何进入这个图片，这样我可以把它添加到我的电子邮件意图是什么？我要对这个正确的方式？谢谢

解决方案

在code线，你就是忘记,, 

  emailIntent.putExtra（Intent.EXTRA_STREAM，Uri.fromFile（MYIMAGE））;

在您的code，申报文件MYIMAGE 在全球范围内的活动，

现在在电子邮件发送code

检查文件是否存在与否，

 如果（myImage.exist（））
{
 串EMAILADDRESS [] = {info@sklep.com，，};
 意图emailIntent =新意图（Intent.ACTION_SEND）;
 emailIntent.putExtra（Intent.EXTRA_EMAIL，EMAILADDRESS）;
 emailIntent.setType（图像/ JPEG）;
 emailIntent.putExtra（Intent.EXTRA_STREAM，Uri.fromFile（MYIMAGE））;
 startActivity（Intent.createChooser（emailIntent，发送邮件））;
}

I have an application that takes a picture and stores the picture internally in a folder that I have created. After taking a picture I want to be able to access it so that I can email it. How can I access the image I have just taken?Below is my code that saves the image internally after the picture has been taken:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        Bundle extras = data.getExtras();
        bmp = (Bitmap) extras.get("data");
        iv.setImageBitmap(bmp);

        File storagePath = new File(
                Environment.getExternalStorageDirectory() + "/DavePics/");
        storagePath.mkdirs();

        File myImage = new File(storagePath, Long.toString(System
                .currentTimeMillis()) + ".jpg");


        Bitmap b = Bitmap.createScaledBitmap(bmp, 320, 480, false);

        try {
            FileOutputStream out = new FileOutputStream(myImage);
            b.compress(Bitmap.CompressFormat.JPEG, 80, out);
            out.flush();
            out.close();
        } catch (Exception e) {
            e.printStackTrace();
        }

    }
}

}

When I check the folder I have created the picture is there. What I want to do now is access that picture so that I can send it in an email from my code below:

@Override
public void onClick(View v) {

    // TODO Auto-generated method stub
    switch (v.getId()) {
    case R.id.bSendPic:

        String emailaddress[] = { "info@sklep.com", "", };

        Intent emailIntent = new Intent(Intent.ACTION_SEND);
        emailIntent.putExtra(Intent.EXTRA_EMAIL, emailaddress);

        //emailIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, pic);

        emailIntent.setType("image/jpeg");
        startActivity(Intent.createChooser(emailIntent, "Send Mail"));

        break;
    case R.id.ibTakePic:

        i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

        startActivityForResult(i, cameraData);
        break;
    }

}

How do I access this pic so that I can add it to my email intent? Am i going about this the right way? Thanks

Edit: This is my full code

public class Camera extends Activity implements View.OnClickListener {

ImageButton ib;
Button b;
ImageView iv;
Intent i;
final static int cameraData = 0;
Bitmap bmp;
File myImage;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.photo);
    initialize();
    InputStream is = getResources().openRawResource(R.drawable.ic_launcher);
    bmp = BitmapFactory.decodeStream(is);

}

private void initialize() {
    ib = (ImageButton) findViewById(R.id.ibTakePic);
    b = (Button) findViewById(R.id.bSendPic);
    iv = (ImageView) findViewById(R.id.ivReturnedPic);
    b.setOnClickListener(this);
    ib.setOnClickListener(this);

}

@Override
public void onClick(View v) {

    // TODO Auto-generated method stub
    switch (v.getId()) {
    case R.id.bSendPic:

        if (myImage.exists()) {

            String emailaddress[] = { "info@sklep.com", "", };

            Intent emailIntent = new Intent(Intent.ACTION_SEND);
            emailIntent.putExtra(Intent.EXTRA_EMAIL, emailaddress);
            emailIntent.setType("image/jpeg");
            emailIntent
                    .putExtra(Intent.EXTRA_STREAM, Uri.fromFile(myImage));
            startActivity(Intent.createChooser(emailIntent, "Send Mail"));

        }

        break;
    case R.id.ibTakePic:

        i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

        startActivityForResult(i, cameraData);
        break;
    }

}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        Bundle extras = data.getExtras();
        bmp = (Bitmap) extras.get("data");
        iv.setImageBitmap(bmp);

        File storagePath = new File(
                Environment.getExternalStorageDirectory() + "/DavePics/");
        storagePath.mkdirs();

        myImage = new File(storagePath, Long.toString(System
                .currentTimeMillis()) + ".jpg");

        Bitmap b = Bitmap.createScaledBitmap(bmp, 320, 480, false);

        try {
            FileOutputStream out = new FileOutputStream(myImage);
            b.compress(Bitmap.CompressFormat.JPEG, 80, out);
            out.flush();
            out.close();
        } catch (Exception e) {
            e.printStackTrace();
        }

    }
}

}

解决方案

The code line you forgot is,,

emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(myImage));

In your code, declare File myImage globally in your activity,

Now at Email send code

check whether file is exist or not,

if(myImage.exist())
{
 String emailaddress[] = { "info@sklep.com", "", };
 Intent emailIntent = new Intent(Intent.ACTION_SEND);
 emailIntent.putExtra(Intent.EXTRA_EMAIL, emailaddress);
 emailIntent.setType("image/jpeg");
 emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(myImage));
 startActivity(Intent.createChooser(emailIntent, "Send Mail"));
}
