Here I will show you how to make an animation image in Android.
It is very easy to make a animation image in background.
The first thing you need is to create a image view in your layout.
<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=".TheDeveloperWorldIsYours" >
<ImageView android:id="@+id/iv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/iv"/>
</RelativeLayout>
The most import line code is
final Handler handler = new Handler();
final Runnable r = new Runnable(){
public void run(){};
}
a Handler, a Runnable and a run.
package com.thedeveloperworldisyours.animationimagen;
import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.widget.ImageView;
public class TheDeveloperWorldIsYours extends Activity {
private static ImageView iv;
final Handler handler = new Handler();
Runnable r;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_the_developer_world_is_yours);
iv = (ImageView) findViewById(R.id.iv);
r = new Runnable()
{
int x = 1;
public void run()
{
switch(x) {
case 1:
iv.setImageResource(R.drawable.base1);
break;
case 2:
iv.setImageResource(R.drawable.base2);
break;
case 3:
iv.setImageResource(R.drawable.base3);
break;
case 4:
iv.setImageResource(R.drawable.base4);
break;
case 5:
iv.setImageResource(R.drawable.base5);
break;
case 6:
iv.setImageResource(R.drawable.base6);
break;
case 7:
iv.setImageResource(R.drawable.base7);
break;
case 8:
iv.setImageResource(R.drawable.base8);
break;
case 9:
iv.setImageResource(R.drawable.base9);
break;
default:
iv.setImageResource(R.drawable.base);
break;
}
if(x==9)
x=1;
else
x++;
handler.postDelayed(this, 1000);
}
};
handler.postDelayed(r, 1000);
}
@Override
protected void onPause() {
// TODO Auto-generated method stub
handler.removeCallbacks(r);
super.onPause();
}
}
