To start another activity, simple call startActivity() with intent.
Intent intent = new Intent(
AndroidAnimationActivity.this, MainActivity.class);
startActivity(intent);
Create a new MainActivity.java, it's the new activity to run after splash screen. Simple display anything now.
package com.exercise.AndroidAnimation;
import android.app.Activity;
import android.os.Bundle;
import android.widget.ImageView;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ImageView image = new ImageView(this);
image.setImageDrawable(
getResources()
.getDrawable(R.drawable.ic_launcher));
setContentView(image);
}
}
Modify run() method of MyTimerTask class in our splach screen activity, AndroidAnimationActivity.java in our example:
package com.exercise.AndroidAnimation;
import java.util.Timer;
import java.util.TimerTask;
import android.app.Activity;
import android.content.Intent;
import android.graphics.drawable.AnimationDrawable;
import android.os.Bundle;
import android.widget.ImageView;
public class AndroidAnimationActivity extends Activity {
AnimationDrawable myAnimationDrawable;
Timer timer;
MyTimerTask myTimerTask;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ImageView myAnimation = (ImageView)findViewById(R.id.myanimation);
myAnimationDrawable
= (AnimationDrawable)myAnimation.getDrawable();
myAnimation.post(
new Runnable(){
@Override
public void run() {
myAnimationDrawable.start();
}
});
//Calculate the total duration
int duration = 0;
for(int i = 0; i < myAnimationDrawable.getNumberOfFrames(); i++){
duration += myAnimationDrawable.getDuration(i);
}
timer = new Timer();
myTimerTask = new MyTimerTask();
timer.schedule(myTimerTask, duration);
}
class MyTimerTask extends TimerTask {
@Override
public void run() {
timer.cancel();
/*
runOnUiThread(new Runnable(){
@Override
public void run() {
Toast.makeText(getApplicationContext(),
"Animation Stopped",
Toast.LENGTH_SHORT).show();
}});
*/
Intent intent = new Intent(
AndroidAnimationActivity.this, MainActivity.class);
startActivity(intent);
}
}
}
Modify AndroidManifest.xml to add <activity> of ".MainActivity".
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.exercise.AndroidAnimation"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:name=".AndroidAnimationActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
</activity>
</application>
</manifest>
From the demo video, it can be noted that:
- If the devie's configuration change (such as orientation) in MainActivity, it will still in MainActivity. Will not re-start the first activity.
- May be you have to special handle the BACK button depends on what you want, because of the first activity still in history stack in this simple implementation.
