通过Scale的方式打开一个新的Activity

1. ScaleActivity.java文件

package cn.com;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class ScaleActivity extends Activity {
	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);

		/* 以findViewById()取得Button对象，并添加onClickListener */
		Button b1 = (Button) findViewById(R.id.Button01);
		b1.setOnClickListener(new Button.OnClickListener() {

			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				/* new一个Intent对象，并指定class */
				Intent intent = new Intent();
				intent.setClass(ScaleActivity.this, Activitya.class);
				/* 调用Activity EX03_10_1 */
				startActivity(intent);
			}
		});
	}
}

2.ScaleAnimationHelper.java文件

package cn.com;

import android.content.Context;
import android.view.View;
import android.view.animation.AccelerateInterpolator;
import android.view.animation.AlphaAnimation;
import android.view.animation.Animation;
import android.view.animation.AnimationSet;
import android.view.animation.ScaleAnimation;

public class ScaleAnimationHelper {
	Context con;

	int order;

	public ScaleAnimationHelper(Context con, int order) {
		this.con = con;
		this.order = order;
	}

	AlphaAnimation myAnimation_Alpha;
	ScaleAnimation myAnimation_Scale;

	public void ScaleOutAnimation(View view) {
		myAnimation_Alpha = new AlphaAnimation(1.0f, 0.1f);
		myAnimation_Scale = new ScaleAnimation(0.1f, 1.0f, 0.1f, 1f,
				Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF,
				0.5f);
		myAnimation_Scale.setInterpolator(new AccelerateInterpolator());

		AnimationSet aa = new AnimationSet(true);
		aa.addAnimation(myAnimation_Alpha);
		aa.addAnimation(myAnimation_Scale);
		aa.setDuration(1000);

		view.startAnimation(aa);
	}

	public void ScaleInAnimation(View view) {

		myAnimation_Scale = new ScaleAnimation(1.0f, 0.0f, 1.0f, 0.0f,
				Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF,
				0.5f);
		myAnimation_Scale.setDuration(1000);
		myAnimation_Scale.setInterpolator(new AccelerateInterpolator());

		AnimationSet aa = new AnimationSet(true);
		aa.addAnimation(myAnimation_Scale);
		// aa.setDuration(1000);

		view.startAnimation(aa);
	}
}

3. Activitya.java文件

package cn.com;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.LinearLayout;
import android.view.View.OnClickListener;

public class Activitya extends Activity implements OnClickListener {
	ViewGroup v;

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.newq);

		v = (LinearLayout) findViewById(R.id.news);

		Button Button01 = (Button) findViewById(R.id.Button01);

		Button01.setOnClickListener(this);

		// 显示layout进行缩放动画效果
		ScaleAnimationHelper scaleHelper = new ScaleAnimationHelper(this, 1);
		scaleHelper.ScaleOutAnimation(v);

	}

	@Override
	public void onClick(View v) {
		// TODO Auto-generated method stub
		// 显示layout进行缩放动画效果
		//ScaleAnimationHelper scaleHelper = new ScaleAnimationHelper(this, 1);
		//scaleHelper.ScaleInAnimation(v);
	}
}

4.main.xml文件

<?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">

	<Button android:text="StartActivity" android:id="@+id/Button01"
		android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
</LinearLayout>

5.newq.xml文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:layout_width="fill_parent" android:background="#123456"
	android:layout_height="fill_parent" android:id="@+id/news"
	android:orientation="vertical">
	<TextView android:text="this is the second activity"
		android:id="@+id/TextView01" android:layout_width="wrap_content"
		android:layout_height="wrap_content"></TextView>
</LinearLayout>

注意2个Activity都需要在Manifest文件中进行申明

和这样的效果一样吗？

overridePendingTransition(R.anim.zoomin, R.anim.zoomout);
