调用相机拍照后返回照片过小的问题

最近通过Intent调用系统相机拍照后，发现返回的照片像素变小，照片质量也变低

代码如下:

1.调用系统相机进行拍照

 

String SD_CARD_TEMP_DIR="/mnt/sdcard/"+"tem.jpg";
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT,Uri.fromFile(new File(SD_CARD_TEMP_DIR)));
startActivityForResult(intent,10);//requestCode:10，任意(If >= 0, this code will be returned in onActivityResult() when the activity exits.)

 

 

2.覆写onActivityResult（），用来处理返回的数据

 

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        String sdStatus = Environment.getExternalStorageState();
        if(!sdStatus.equals(Environment.MEDIA_MOUNTED))
        {
            return;
        }
          ContentResolver resolver = getContentResolver();
            try {
                File f = new File(SD_CARD_TEMP_DIR);
                try {
                    Uri capturedImage = Uri.parse(android.provider.MediaStore.Images.Media.insertImage(
                            getContentResolver(), f.getAbsolutePath(), null, null));
                    // 将图片内容解析成字节数组
                    mContent = readStream(resolver.openInputStream(Uri.parse(capturedImage.toString())));
                    // 将字节数组转换为ImageView可调用的Bitmap对象
                    bitmap = getPicFromBytes(mContent, null);
                    //把得到的图片绑定在控件上显示
                    ((ImageView)findViewById(R.id.camera_dispaly)).setImageBitmap(bitmap);
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                }
            } catch (Exception e) {
            }
}

3.OK
