Android image rotated via xml file

Question

I try to make the image file rotate in place and try my best, every tutorial that I find does it differently.

Can someone point out where I am not here.

Gameplay.java

import android.app.Activity; import android.graphics.drawable.AnimationDrawable; import android.os.Bundle; import android.widget.ImageView; public class GamePlay extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.gameplay); ImageView logo = (ImageView)findViewById(R.id.mainlogo); logo.setBackgroundResource(R.anim.rotate); AnimationDrawable frameAnimation = (AnimationDrawable) logo.getBackground(); frameAnimation.start(); } } 

rotate.xml

 <?xml version="1.0" encoding="UTF-8"?> <rotate xmlns:android="http://schemas.android.com/apk/res/android" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="0" android:toDegrees="360" android:drawable="@drawable/logo" /> 

gameplay.xml

 <ImageView android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/mainlogo" android:src="@drawable/logo"> </ImageView> 

Answer 1

Change rotate.xml to

 <?xml version="1.0" encoding="UTF-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" > <rotate xmlns:android="http://schemas.android.com/apk/res/android" android:duration="1200" android:fromDegrees="0" android:pivotX="50%" android:pivotY="50%" android:repeatCount="infinite" android:toDegrees="360" /> </set> 

put it in the res / anim / folder folder

and try to run the animation

 ImageView logo = (ImageView)findViewById(R.id.mainlogo); Animation rotateAnimation = AnimationUtils.loadAnimation(context, R.anim.rotate); logo.startAnimation(rotateAnimation); 

Answer 2

Try this code; It works for me:

 ImageView img=(ImageView)findViewById(R.id.ImageView01); Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.snoopy); // Getting width & height of the given image. int w = bmp.getWidth(); int h = bmp.getHeight(); // Setting post rotate to 90 Matrix mtx = new Matrix(); mtx.postRotate(90); // Rotating Bitmap Bitmap rotatedBMP = Bitmap.createBitmap(bmp, 0, 0, w, h, mtx, true); BitmapDrawable bmd = new BitmapDrawable(rotatedBMP); img.setImageDrawable(bmd); }
