  17. 17. public View getView( int position, View convertView, ViewGroup parent) { LayoutInflater inflater = getLayoutInflater(); ImageView i = (ImageView) inflater.inflate( R.layout.image, parent, false ); i.setImageResource(mImageIds[position]); i.setScaleType(ImageView.ScaleType. FIT_XY ); i.setBackgroundResource(mGalleryItemBackground); return i; } override getView()
  18. 18. BitmapFactory.Options options = new BitmapFactory.Options(); options.inJustDecodeBounds = false; options.inDither = false; options.inScaled = false; options.inPreferredConfig = Bitmap.Config.ARGB_8888; options.inTargetDensity = screenDensity; // 160 dpi Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.sample_0, options); use BitmapFactory.Options()

  45. 47. stacking is better
  46. 49. FragmentTransaction ft = getFragmentManager().beginTransaction() ; ft.setCustomAnimations( R.anim.slide_in_left , R.anim.slide_out_right ); DetailsFragment newFragment = DetailsFragment.newInstance(); ft.replace (, newFragment, &quot;detailFragment&quot;); // Start the animated transition. ft.commit(); slide fragments
  47. 50. public void onClick(View v) {    FragmentTransaction ft = getFragmentManager().beginTransaction();                ft.setCustomAnimations( android.R.animator.fade_in, android.R.animator.fade_out);        if ( fragment.isHidden() ) {   ;          button.setText(&quot;Hide&quot;);       } else {             ft.hide(fragment);          button.setText(&quot;Show&quot;)       }        ft.commit(); } use show() and hide()
  48. 51. ok. what was that animation part?
  49. 52. <set> <objectAnimator xmlns:android=&quot;; android:duration=&quot;500&quot; android:valueFrom=&quot;-1280&quot; android:valueTo=&quot;0&quot; android:valueType=&quot;floatType&quot; android:propertyName=&quot;x&quot; /> </set> create an xml animation
  50. 53. if (fragment.isHidden()) { ft.setCustomAnimations( R.anim.infromleft, R.anim.outtoleft);; button.setText(&quot;Hide&quot;); } set the custom animation

  60. 64. ObjectAnimator visToInvis = ObjectAnimator.ofFloat( visibleList, &quot;rotationY&quot;, 0f, 90f); visToInvis.setDuration(500); visToInvis.setInterpolator(accelerator); final ObjectAnimator invisToVis = ObjectAnimator.ofFloat( invisibleList, &quot;rotationY&quot;, -90f, 0f); invisToVis.setDuration(500); invisToVis.setInterpolator(decelerator); and an objectanimator
