之前看到一個App的佈局仿win8很漂亮，對它每個色塊點選有縮放效果很好奇，動手試了一下。

直接上程式碼。。。。。。。。

MainActivity.java

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.LinearLayout;

public class MainActivity extends Activity implements OnTouchListener {

	private LinearLayout layout1, layout2;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		layout1 = (LinearLayout) findViewById(R.id.layout1);
		layout2 = (LinearLayout) findViewById(R.id.layout2);

		layout1.setOnTouchListener(this);
		layout2.setOnTouchListener(this);
	}

	@Override
	public boolean onTouch(View v, MotionEvent event) {
		// TODO Auto-generated method stub
		
		//設定Animation
		Animation animDwon = AnimationUtils.loadAnimation(this, R.anim.show_down);
		Animation animUp = AnimationUtils.loadAnimation(this, R.anim.show_up);
		
		LinearLayout layout = (LinearLayout) v;
		switch (event.getAction()) {
		case MotionEvent.ACTION_DOWN:
			layout.startAnimation(animDwon);
			animDwon.setFillAfter(true);
			break;

		case MotionEvent.ACTION_UP:
			layout.startAnimation(animUp);
			animUp.setFillAfter(true);
			break;
		}
		return true;	//這時必須返回true，不然 MotionEvent.ACTION_UP 沒效果
	}

}
