this is quite difficult to explain, but here we go!
Ok, the transition until I get the Fragment where the Animation is placed
would be:
MainActivity (extends Activity) - loginActivity (extendsActivity) - now I
call:
Intent homeIntent = new Intent(loginActivity.this, HomeActivity.class);Bundle
bundle = new Bundle();
bundle.putSerializable(risposta,(Serializable)risposta);
homeIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // read below
homeIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK); // read below
homeIntent.putExtras(bundle);
startActivity(homeIntent);
which starts *HomeActivity* which extends *FragmentActivity* and at the end
of onCreateView() I add my Fragment *CircleFragment* that @Overrides this
on onResume():
RotateAnimation rotateAnimation1 = new RotateAnimation(0, 360,
Animation.RELATIVE_TO_SELF, 0.5f,
Animation.RELATIVE_TO_SELF, 0.5f);
rotateAnimation1.setInterpolator(new LinearInterpolator());
rotateAnimation1.setDuration(4000);
rotateAnimation1.setRepeatCount(Animation.INFINITE);
radar.startAnimation(rotateAnimation1);
or XML (tried both):
?xml version=1.0 encoding=utf-8?rotate
xmlns:android=http://schemas.android.com/apk/res/android;
android:fromDegrees=0
android:interpolator=@android:anim/linear_interpolator
android:toDegrees=360
android:pivotX=50%
android:pivotY=25%
android:duration=4000
android:startOffset=0/
*WHAT HAPPENS?*
*SOMETIMES* it works bad (sometimes fine!): it starts arround ~(50%, 25%)
(or 0.5, 0.25), not exactly (calculated) but if I let the screen go off and
I resume it, everything works again :O
*WHY IS IT STRANGE?*
1. do you see the two lines commented which cleans the task and start
the activity on top ? if I don't set that, everything is OK
2. If I start it as MainActivity - HomeActivity and doing finish
(instead clearing tasks), it works as well fine.
What's happening?
Thanks in advance.
