我正在开发一个应用程序,可以使用额外裁剪选项使用相机意图显示来自相机的照片。代码在大多数设备上工作正常,但是当我尝试在我的全新Galaxy Note3中测试时,它崩溃并且没有正常运行,而且所拍摄的图像仍然很大并且#34;差不多4 MB& #34;这是如此之大,以至于在imageview中显示。如果无论如何都可以指望我避免这种情况吗?
下面是我的代码:
Intent intent = new Intent(
"android.media.action.IMAGE_CAPTURE");
file = getOutputMediaFile();
intent.putExtra("crop", "true");
intent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(file));
intent.putExtra("outputFormat",
Bitmap.CompressFormat.JPEG
.toString());
intent.putExtra(
MediaStore.EXTRA_SCREEN_ORIENTATION,
ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
startActivityForResult(intent,
ACTION_REQUEST_CAMERA);
和activityforresult
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
switch (requestCode) {
case ACTION_REQUEST_CAMERA:
if (data != null) {
try {
int inWidth = 0;
int inHeight = 0;
InputStream in = new FileInputStream(
file.getAbsolutePath());
// decode image size (decode metadata only, not the
// whole image)
BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeStream(in, null, options);
in.close();
in = null;
// save width and height
inWidth = options.outWidth;
inHeight = options.outHeight;
// decode full image pre-resized
in = new FileInputStream(file.getAbsolutePath());
options = new BitmapFactory.Options();
// calc rought re-size (this is no exact resize)
options.inSampleSize = Math.max(inWidth / 350,
inHeight / 550);
// decode full image
Bitmap roughBitmap = BitmapFactory.decodeStream(in,
null, options);
// calc exact destination size
Matrix m = new Matrix();
RectF inRect = new RectF(0, 0, roughBitmap.getWidth(),
roughBitmap.getHeight());
RectF outRect = new RectF(0, 0, 700, 800);
m.setRectToRect(inRect, outRect,
Matrix.ScaleToFit.CENTER);
float[] values = new float[9];
m.getValues(values);
// resize bitmap
Bitmap resizedBitmap = Bitmap.createScaledBitmap(
roughBitmap,
(int) (roughBitmap.getWidth() * values[0]),
(int) (roughBitmap.getHeight() * values[4]),
true);
// save image
try {
FileOutputStream out = new FileOutputStream(
file.getAbsolutePath());
resizedBitmap.compress(Bitmap.CompressFormat.JPEG,
90, out);
fullphoto = resizedBitmap;
setPic(file.getAbsolutePath(), camera);
} catch (Exception e) {
Log.e("Image", e.getMessage(), e);
}
} catch (IOException e) {
Log.e("Image", e.getMessage(), e);
}
}
// fullphoto = BitmapFactory.decodeFile(file.getAbsolutePath());
// photo = decodeSampledBitmapFromFile(file.getAbsolutePath(),
// 100, 100);
// camera.setImageBitmap(imghelper.getRoundedCornerBitmap(
// fullphoto, 10));
iscamera = "Yes";
firsttime = false;
break;
