我正在实现一个允许用户将照片从他们的设备库上传到 ImageView 的 android 程序。将其保存在云端。我的代码适用于小照片,但较大的照片导致应用程序停止。我收到此错误:
位图太大,无法上传到纹理中(4128x2322,最大值=4096x4096)
我尝试在使用之前问题的建议显示上传的照片之前调整其大小,但它们不起作用。我不确定我的代码有什么问题。
任何帮助,将不胜感激。这是我上次尝试的代码:
{
// omitted code segment from onCreate...
browseButton = ((Button) findViewById(R.id.browse_button));
browseButton.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"), SELECT_PICTURE);
}
}
);
}
//end on create
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (resultCode == RESULT_OK)
{
if (requestCode == SELECT_PICTURE)
{
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
Bitmap bitmap = BitmapFactory.decodeFile(selectedImagePath);
// Convert it to byte
ByteArrayOutputStream stream = new ByteArrayOutputStream();
// Compress image to lower quality scale 1 - 100
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
image = stream.toByteArray();
bitmap = BitmapFactory.decodeByteArray(image, 0, image.length);
Bitmap toyImageScaled = Bitmap.createScaledBitmap(bitmap, 200, 200
* bitmap.getHeight() / bitmap.getWidth(), false);
// Override Android default landscape orientation and save portrait
Matrix matrix = new Matrix();
matrix.postRotate(90);
Bitmap rotatedScaledToyImage = Bitmap.createBitmap(toyImageScaled, 0,
0, toyImageScaled.getWidth(), toyImageScaled.getHeight(),
matrix, true);
toyPreview.setImageBitmap(bitmap);
}
}
}
public String getPath(Uri uri)
{
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
