In android the default transition between activities is to slide from left to right.
But with custom animations we can change that.
First create a folder inside the res/drawable folder called “anim”.
Then create a file named “fade.xml” and copy this code into it.
<?xml version="1.0" encoding="utf-8"?><alpha xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/accelerate_interpolator" android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="@android:integer/config_longAnimTime" /> |
create another file named “hold.xml” in the same place
hold.xml.
<?xml version="1.0" encoding="utf-8"?><translate xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/accelerate_interpolator" android:fromXDelta="0" android:toXDelta="0" android:duration="@android:integer/config_longAnimTime" /> |
activity_animation.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:padding="4dip" android:gravity="center_horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="0" android:paddingBottom="4dip" android:text="Sample Animation"/> <Button android:id="@+id/fade_animation" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="fade In"> <requestFocus /> </Button></LinearLayout> |
Now the main java file.
package pack.coderzheaven;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;public class ActivityAnimation extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_animation); Button button = (Button)findViewById(R.id.fade_animation); button.setOnClickListener(mFadeListener); } private OnClickListener mFadeListener = new OnClickListener() { public void onClick(View v) { startActivity(new Intent(ActivityAnimation.this, SecondClass.class)); overridePendingTransition(R.anim.fade, R.anim.hold); } };} |
package pack.coderzheaven;
import android.app.Activity;
import android.os.Bundle;
public class SecondClass extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
main.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" ><TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Second Class" /></LinearLayout> |
