我有一个表单,用户可以点击图像并在imageview中设置。当手机保持纵向模式并单击图像时,一切正常,点击图像在图像视图中设置。问题是,如果用户在纵向模式下单击捕获图像按钮然后旋转手机以单击图像,则在onActivityResult中我得到位图null。 有没有解决方案。
这是我的onActivtiyResult
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch (requestCode) {
case 1:
try {
bitmap = AppUtils.decodeFile(file.getPath(), 100, 100);
registrationBean.setImage(file.getPath());
imageList.add(file.getPath());
AppUtils.writeList(this,imageList,"images");
}catch (Exception e) {
e.printStackTrace();
}
if (bitmap != null) {
iv_profile.setImageBitmap(bitmap);
retake_photo.setAlpha(1);
retake_photo.setClickable(true);
take_photo.setClickable(false);
take_photo.setAlpha((float) 0.60);
}
break;
case 2:
try {
String uriImage;
imageUri = imageReturnedIntent.getData();
final InputStream imageStream = getContentResolver().openInputStream(imageUri);
final Bitmap selectedImage = BitmapFactory.decodeStream(imageStream);
imageStream.close();
String path = getPath(imageUri);
imageList.add(path);
AppUtils.writeList(getBaseContext(), imageList, "images");
registrationBean.setImage(path);
if (selectedImage != null) {
iv_profile.setImageBitmap(selectedImage);
retake_photo.setAlpha(1);
}
uriImage = imageUri.toString();
registrationBean.setImage(uriImage);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
catch (OutOfMemoryError e)
{
e.printStackTrace();
}
break;
}
}
调用startActivityForResult的方法
private void selectImage() {
final CharSequence[] options = {"Take a Picture", "Choose from Gallery", "Cancel"};
AlertDialog.Builder builder = new AlertDialog.Builder(ActivityForm.this);
builder.setCancelable(false);
builder.setTitle("Select Profile Photo!");
builder.setItems(options, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int item) {
if (options[item].equals("Take a Picture")) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
i = appSharedPreference.getImageNumber();
file = new File(Environment.getExternalStorageDirectory(), "temp" + i + ".jpg");
i++;
appSharedPreference.setImageNumber(i);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
img_path = Environment.getExternalStorageDirectory() + "/temp.jpg";
startActivityForResult(intent, 1);
} else if (options[item].equals("Cancel")) {
dialog.dismiss();
}
if (options[item].equals("Choose from Gallery")) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Intent photoPickerIntent = new Intent(Intent.ACTION_OPEN_DOCUMENT, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
photoPickerIntent.setType("image/*");
photoPickerIntent.addCategory(photoPickerIntent.CATEGORY_OPENABLE);
startActivityForResult(photoPickerIntent, 2);
} else if (options[item].equals("Cancel")) {
dialog.dismiss();
} else {
Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
img_path = MediaStore.Images.Media.EXTERNAL_CONTENT_URI.toString();
startActivityForResult(intent, 2);
}
}
}
});
builder.show();
}
