ACTION_IMAGE_CAPTURE を使用してキャプチャした後、画像をフルサイズで保存する際に問題が発生しました。画像が非常に小さくなりました。解像度は 27X44 です。1.5 Android エミュレーターを使用しています。これがコードです。
myImageButton02.setOnClickListener
(
new OnClickListener()
{
@Override
public void onClick(View v)
{
// create camera intent
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
//Grant permission to the camera activity to write the photo.
intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
//saving if there is EXTRA_OUTPUT
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File
(Environment.getExternalStorageDirectory(), "testExtra" + String.valueOf
(System.currentTimeMillis()) + ".jpg")));
// start the camera intent and return the image
startActivityForResult(intent,1);
}
}
);
@Override
protected void onActivityResult (int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
// if Activity was canceled, display a Toast message
if (resultCode == RESULT_CANCELED)
{
Toast toast = Toast.makeText(this,"camera cancelled", 10000);
toast.show();
return;
}
// lets check if we are really dealing with a picture
if (requestCode == 1 && resultCode == RESULT_OK)
{
String timestamp = Long.toString(System.currentTimeMillis());
// get the picture
Bitmap mPicture = (Bitmap) data.getExtras().get("data");
// save image to gallery
MediaStore.Images.Media.insertImage(getContentResolver(), mPicture, timestamp, timestamp);
}
}
}
