原标题：How to take photo from camera and add photo gallery in android application?

我是甲型散射器,需要帮助,即试图从摄像机中摄取照片,并如何添加陶瓷。 我的代码如下!

感谢!

send_zoo_btn.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
            String base64string = "";
            // bitmap = i.getDrawingCache();
            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
            ImageByte = stream.toByteArray();
            base64string = Base64.encodeBytes(ImageByte);

            db.execSQL("insert into newanimal(path,selece_animal) values( "
                    + base64string + " , " + id + "  )");
            Toast.makeText(ThirdActivity.this, "Data inserted", 1).show();
            Intent intent = new Intent().setClass(ThirdActivity.this,
                    ZoobuzzActivity.class);
            startActivity(intent);
        }
    });
}

下表按活动结果方法分列

使用照相机

Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);

startActivityForResult(intent, PICK_IMAGE_FROM_CAMERA);



@Override
protected void onActivityResult(int requestCode , int resultCode ,
        Intent data) {

    // TODO Auto-generated method stub


    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        switch (requestCode) {
            case PICK_IMAGE_FROM_CAMERA:

                Uri uri = data.getData();
                imageview.setImageURI(uri);

                break;

}
    }
}

在特定地点保存SD卡的形象

if (uri != null) {
        String SD_Card_Path = Environment.getExternalStorageDirectory()
                .toString();
        String Our_Path = SD_Card_Path + "/NewFolder/Images/";
        OutputStream fOut = null;
        ImageFullName = Image_Name + "_" + System.currentTimeMillis()
                + ".jpg";
        File file = new File(Our_Path + ImageFullName);
        try {
            fOut = new FileOutputStream(file);

            Bitmap mBitmap = null;
            mBitmap = Media.getBitmap(this.getContentResolver(),
                    myCaptureUri);

            mBitmap.compress(Bitmap.CompressFormat.JPEG, 100, fOut);
            fOut.flush();
            fOut.close();
        }
        catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
