下面是我在从相机拍摄照片后code snippet
重定向到设备的相关位置。cropping app
我通常遵循这个例子。但是在从相机拍摄的照片和在裁剪应用程序中提供照片之间的阶段/时刻,它会显示不断加载并使我的应用程序非常无响应。如果这种情况至少发生一次,那么每次我打开应用程序时,它都会显示正在加载。
此问题不会发生在one scenario
--> 当我不移动我的设备时(即,仅当没有发生屏幕方向时)。有人可以建议我避免这个问题吗?
public void shotFromCamera(View view)
{
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, imageCaptureUri);
try {
intent.putExtra("return-data", true);
startActivityForResult(intent, PICK_FROM_CAMERA);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
}
}
protected void onActivityResult(int requestCode, int resultCode,Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if(resultCode==RESULT_OK && requestCode == PICK_FROM_CAMERA){
doCrop();
} else if(resultCode == RESULT_OK && requestCode == CROP_FROM_CAMERA)
{
Bundle extras = data.getExtras();
if (extras != null) {
Bitmap photoBitmap = extras.getParcelable("data");
imageView.setImageBitmap(photoBitmap);
if(mImageCaptureUri != null)
{
File f = new File(mImageCaptureUri.getPath());
if (f.exists()) f.delete();
}
mImageCaptureUri = Uri.fromFile(new File(Environment.getExternalStorageDirectory()+ "/MyApp",
"avatar" + String.valueOf(System.currentTimeMillis()) + ".jpg"));
File file = new File(mImageCaptureUri.getPath());
selectedImagePath = mImageCaptureUri.getPath();
Log.d("pic1 ","pic to be created: "+selectedImagePath);
OutputStream fOut = null;
try {
fOut = new FileOutputStream(file);
photoBitmap.compress(Bitmap.CompressFormat.JPEG, 85, fOut);
fOut.flush();
fOut.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch(IOException e)
{
e.printStackTrace();
}
}
}
}
private void doCrop() {
final ArrayList<CropOption> cropOptions = new ArrayList<CropOption>();
Intent intent = new Intent("com.android.camera.action.CROP");
intent.setType("image/*");
List<ResolveInfo> list = getPackageManager().queryIntentActivities( intent, 0 );
int size = list.size();
if (size == 0) {
Toast.makeText(this, "Can not find image crop app", Toast.LENGTH_SHORT).show();
return;
} else {
intent.setData(imageCaptureUri);
intent.putExtra("outputX", 200);
intent.putExtra("outputY", 200);
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("scale", true);
intent.putExtra("return-data", true);
if (size == 1) {
Intent i = new Intent(intent);
ResolveInfo res = list.get(0);
i.setComponent( new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
startActivityForResult(i, CROP_FROM_CAMERA);
}
}
为了澄清我的问题,我按原样运行了该示例中的源代码,同样的问题发生了。我已经运行了其他几个重定向到裁剪应用程序的示例。在上述解释阶段更改方向时也会发生同样的问题。
PS:如果有人有工作示例,即使在方向更改上也确实有效,我很乐意接受它作为答案。
