How to Set Animation Using View in Android

Procedure

1. Start Eclipse IDE.
2. Create a new project.
3. Create two Java files, one is AnimationUsingView.java and the second is MyView.java.
4. Create an activity_animation_using_view.xml file for layout design.
5. In MyView.java file add an image using BitmapFactory and then in the onDraw function use a canvas with drawLine,drawBitmap, and drawColor.
6. In the AnimationUsingView.java file extends with Activity and declares a variable of MyView type then add animation_using_view in onCreateOptionsMenu.

The code is given below.

 

MyView.java

package a.v;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.view.View;
public class MyView extends View {
 Bitmap ball;
 float change = 0;
 public MyView(Context context) {
  super(context);
  ball = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
 }
 @Override
 protected void onDraw(Canvas canvas) {
  super.onDraw(canvas);
  Paint pi = new Paint();
  pi.setColor(Color.YELLOW);
  pi.setStrokeWidth(45);
  canvas.drawColor(Color.RED);
  canvas.drawBitmap(ball, canvas.getWidth() / 2, change, null);
  canvas.drawLine((canvas.getWidth() / 2) + 20, 0, (canvas.getWidth() / 2) + 20, change, pi);
  if (change < canvas.getHeight()) {
   change += 5;
  } else {
   change = 0;
  }
  invalidate();
 }
}

AnimationUsingView.java

package a.v;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class AnimationUsingView extends Activity {
 MyView a1;
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  a1 = new MyView(getApplicationContext());
  setContentView(a1);
 }
 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  getMenuInflater().inflate(R.menu.animation_using_view, menu);
  return true;
 }
}

activity_animation_using_view.xml

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"

      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:paddingBottom="@dimen/activity_vertical_margin"
      android:paddingLeft="@dimen/activity_horizontal_margin"
      android:paddingRight="@dimen/activity_horizontal_margin"
     android:paddingTop="@dimen/activity_vertical_margin"
     tools:context=".AnimationUsingView" >

</RelativeLayout>
