java - Rotate an imageView at an angle using Seekbar -

I will just rotate min to max . But for this I have used several images to show progress Can someone recommend me a way to use an image that can rotate at maximum one angle from the minimum.

I know there are two possible ways to achieve this.

1. Use of animation classes
2. Custom

I will rotate this image just by using any number of SeekBar

< / P>

To touch an image

  Private zero rotate (float degree) {last rotate animation rotate element = new rotate animation (0.0f, degree, rotate animation RELATIVE_TO_SELF, 0.5 F, Rotat Animation. RELATIVE_TO_SELF, 0.5F); RotateAnim.setDuration (0); RotateAnim.setFillAfter (true); Imgview.startAnimation (rotateAnim); }  

second approach

  imageView.setRotation (angle); // matrix   
  matrix matrix = new matrix (); Can use the matrix; But I'm going to API & gt; = 11  
 
  imageView.setScaleType (ScaleType.MATRIX); // essential matrix.postRotate (float angle, pivX, pivY); ImageView.setImageMatrix (matrix);  

How can I set SequeBar Minimum and Maximum to Start and End Angle? Which approach is better and should I put it in FrameLayout to rotate it with freely

You can do this like:

  // basic Load bitmap (500 x 500 pixels) bitmap bitmap.org = bitmapfichter Decode processing (getResources (), R.drawable.android); Int width = bitmapOrg.width (); Int height = bitmapOrg.height (); Matrix matrix matrix = new matrix (); // bitmap matrix PostRotate (45); // The size of the new bitmap bitmap has been resized to Bitmap = Bitmap.SerateMap (bitmaporgh, 0, 0, width, height, matrix, true); // Allow setting to set up Biltmap with a bitmap; // image view, image button or any bitmap drauble BMD = to set new bitmaprodvate (resized bitmap); // ImageView imageView.setImageDrawable set on Drawable (BMD);  

Check this for details.

  matrix. PostRotate (45); // is the angle degree to rotate here 45
