copied!<p>You could do something like this, using your own image(the image of the man):</p> <p>Main Class:</p> <pre><code>package com.android.animation; import android.app.Activity; import android.os.Bundle; public class Main extends Activity { Animation myView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); myView = new Animation(this); setContentView(myView); } } </code></pre> <p>Animation Class:</p> <pre><code>package com.android.animation; import android.content.Context; import android.graphics.Bitmap; import android.graphics.BitmapFactory; import android.graphics.Canvas; import android.graphics.Color; import android.view.View; public class Animation extends View { Bitmap gBall; float changingY; public Animation(Context content) { super(content); gBall = BitmapFactory.decodeResource(getResources(), R.drawable.ball); changingY = 0; } @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); canvas.drawColor(Color.BLACK); canvas.drawBitmap(gBall, (canvas.getWidth()/2), changingY, null); if(changingY < canvas.getHeight()) changingY += 10; else changingY = 0; invalidate(); } } </code></pre> <p>XML file: </p> <pre><code><?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> </LinearLayout> </code></pre> <p>In fact, if you want you can go ahead and copy paste my code and see how it works(make sure to put an image in the drawable-hdpi folder)... you should be able to use it as a template for your project. Hope it helps!</p> <p>P.S You could of course, change the <code>ChangingY</code> variable to <code>ChangingX</code> (for example; of course you would have to change a couple other things like the <code>drawBitmap()</code> method.. not hard though) to make the ball move in a horizontal line... see how it works out for you.</p>
