Question

我想获取使用我的应用拍摄的照片缩略图。但我没有使用以下代码获取它。请帮忙。这是代码：

 Intent i = new
Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
File file = new 
File(Environment.getExternalStorageDirectory(), "MyImages");
file.mkdirs();
File image = new File(file, "picture1" + ".png");
Uri uriSavedImage = Uri.fromFile(image);
i.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);

final int THUMBSIZE = 64;
Bitmap ThumbImage = ThumbnailUtils.extractThumbnail(BitmapFactory.decodeFile(image.getPath()),
                    THUMBSIZE, THUMBSIZE);

startActivity(i);

Answer 1

首先

static final int REQUEST_IMAGE_CAPTURE = 1;

private void dispatchTakePictureIntent() {
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
        startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
    }
}

然后

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
        Bundle extras = data.getExtras();
        Bitmap imageBitmap = (Bitmap) extras.get("data");
        mImageView.setImageBitmap(imageBitmap);
    }
}
