Android : View Animation

Pembelajaran selanjutnya adalah membuat tampilan Animasi yang terbagi animasi pada jam analog dan animasi pada Linearlayout.

• Pertama kita buat project baru dengan kriteria

Nama : viewanimation

package name : tutorial.viewanimation

Activity Name : ViewanimationActivity

• Selanjutnya kita buka file main.xml dan lakukan perubahan seperti berikut:

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"  android:id="@+id/mylayout"  android:orientation="vertical"  android:layout_width="fill_parent"  android:layout_height="fill_parent"  >  <Button   android:id="@+id/start1"   android:layout_width="fill_parent"   android:layout_height="wrap_content"   android:text="Start Animation Pada LinearLayout"   />  <Button   android:id="@+id/start2"   android:layout_width="fill_parent"   android:layout_height="wrap_content"   android:text="Start Animation Pada AnalogClock"   />  <AnalogClock   android:id="@+id/myClock"   android:layout_width="wrap_content"   android:layout_height="wrap_content"   /> </LinearLayout>

• Selanjutnya buka file ViewanimationActivity.java dan lakukan perubahan seperti berikut.

package tutorial.viewanimation; import android.app.Activity; import android.graphics.Matrix; import android.os.Bundle; import android.view.View; import android.view.animation.Animation; import android.view.animation.LinearInterpolator; import android.view.animation.Transformation; import android.widget.AnalogClock; import android.widget.Button; import android.widget.LinearLayout; public class ViewanimationActivity extends Activity {     /** Called when the activity is first created. */     @Override     public void onCreate(Bundle savedInstanceState) {      super.onCreate(savedInstanceState);      setContentView(R.layout.main);      Button myStartButton1 = (Button)this.findViewById(R.id.start1);      myStartButton1.setOnClickListener(myStartButton1OnClickListener);      Button myStartButton2 = (Button)this.findViewById(R.id.start2);      myStartButton2.setOnClickListener(myStartButton2OnClickListener);     }     private Button.OnClickListener myStartButton1OnClickListener =      new Button.OnClickListener(){    @Override    public void onClick(View v) {     // TODO Auto-generated method stub     LinearLayout myAnimation = (LinearLayout)findViewById(R.id.mylayout);        myAnimation.startAnimation(new ViewAnimation());    }     };         private Button.OnClickListener myStartButton2OnClickListener =      new Button.OnClickListener(){    @Override    public void onClick(View v) {     // TODO Auto-generated method stub     AnalogClock myAnimation = (AnalogClock)findViewById(R.id.myClock);        myAnimation.startAnimation(new ViewAnimation());    }     };         public class ViewAnimation extends Animation     {      int centerX, centerY;      @Override      public void initialize(int width, int height, int parentWidth,        int parentHeight)      {       super.initialize(width, height, parentWidth, parentHeight);       setDuration(5000);       setFillAfter(true);       setInterpolator(new LinearInterpolator());       centerX = width/2;       centerY = height/2;      }           @Override   protected void applyTransformation(float interpolatedTime,     Transformation t) {    // TODO Auto-generated method stub       final Matrix matrix = t.getMatrix();       matrix.setScale(interpolatedTime, interpolatedTime);   }     } }

• Terakhir kita jalankan aplikasi. . :)
