我正在捕捉图像并将其设置为图像视图。
public void captureImage() {
Intent intentCamera = new Intent("android.media.action.IMAGE_CAPTURE");
File filePhoto = new File(Environment.getExternalStorageDirectory(), "Pic.jpg");
imageUri = Uri.fromFile(filePhoto);
MyApplicationGlobal.imageUri = imageUri.getPath();
intentCamera.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intentCamera, TAKE_PICTURE);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intentFromCamera) {
super.onActivityResult(requestCode, resultCode, intentFromCamera);
if (resultCode == RESULT_OK && requestCode == TAKE_PICTURE) {
if (intentFromCamera != null) {
Bundle extras = intentFromCamera.getExtras();
if (extras.containsKey("data")) {
bitmap = (Bitmap) extras.get("data");
}
else {
bitmap = getBitmapFromUri();
}
}
else {
bitmap = getBitmapFromUri();
}
// imageView.setImageBitmap(bitmap);
imageView.setImageURI(imageUri);
}
else {
}
}
public Bitmap getBitmapFromUri() {
getContentResolver().notifyChange(imageUri, null);
ContentResolver cr = getContentResolver();
Bitmap bitmap;
try {
bitmap = android.provider.MediaStore.Images.Media.getBitmap(cr, imageUri);
return bitmap;
}
catch (Exception e) {
e.printStackTrace();
return null;
}
}
但问题是，某些设备上的图像每次旋转时。例如，在三星设备上，它工作得很好，但在索尼Xperia上，图像旋转了90度，在东芝Thrive(平板电脑)上旋转了180度。
