我在写这个问题之前经常搜索。 我有一个Intent从相机中选择一个图像,其中extra_output存储在Uri中
当图像以纵向捕捉和/或没有自动旋转时,效果非常好。 但是,如果您处于横向和自动旋转状态,则某些模型会给我错误。
我的意图代码:
Intent camera = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
camera.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(imageFile));
startActivityForResult(camera, REQUEST_CAMERA);
我的onActivityResult片段代码:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
ImageView imageFoto = (ImageView) findViewById(R.id.imageIncidenciaDetail);
imatgeOriginal = null;
if (requestCode == REQUEST_CAMERA && resultCode == RESULT_OK) {
//if(imageFile != null)
imatgeOriginal = BitmapFactory.decodeFile(imageFile.getAbsolutePath());
我实际上有两个不同的错误:

Android Manifest活动代码:
<activity
android:name=".incidencia_detail"
android:label="@string/title_activity_incidencia_detail"
android:screenOrientation="portrait"
android:configChanges="orientation"

我可以执行if和并检查图像是否为空。如果我这样做应用程序没有崩溃,但图像为空。
答案 0 :(得分:1)
将imageFile
路径保存在saveInstanceState(Bundle out)
的{{1}}上,并Activity
恢复imageFile
,如果onCreate(Bundle savedInstanceState)
。您可能需要将savedInstanceState != null
存储为imageFile
,以便将其保存到String
。
