android動畫編

四月份來了，我也要加緊學習了，下面的動畫類型

 

package com.smart;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.view.animation.TranslateAnimation;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Spinner;

public class Main extends Activity implements AdapterView.OnItemSelectedListener
{
    private static final String[] INTERPOLATORS={
        "加快", "減速", "加快/減速", "預料",
        "過沖", "預計/過沖", "彈跳"
    };//類型

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Spinner s=(Spinner)findViewById(R.id.spinner);
        ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,INTERPOLATORS);
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        s.setAdapter(adapter);//獲得控件
        s.setOnItemSelectedListener(this);


    }


    @Override
    public void onItemSelected(AdapterView<?> parent, View v, int position,
            long id) {
        final View target=(View)findViewById(R.id.target);
        final View targetParent=(View)target.getParent();//獲得動畫
        Animation animation= new TranslateAnimation(0.0f, targetParent
                .getWidth()
                - target.getWidth()
                - targetParent.getPaddingLeft()
                - targetParent.getPaddingRight(), 0.0f, 0.0f);
        animation.setDuration(1000);
        animation.setStartOffset(300);
        animation.setRepeatMode(Animation.RESTART);
        animation.setRepeatCount(Animation.INFINITE);
        //選擇動來類型
        switch (position) {
        case 0:
            animation.setInterpolator(AnimationUtils.loadInterpolator(this, android.R.anim.accelerate_interpolator));

            break;
        case 1:
            animation.setInterpolator(AnimationUtils.loadInterpolator(this, android.R.anim.decelerate_interpolator));

            break;
        case 2:
            animation.setInterpolator(AnimationUtils.loadInterpolator(this, android.R.anim.accelerate_decelerate_interpolator));

            break;
        case 3:
            animation.setInterpolator(AnimationUtils.loadInterpolator(this, android.R.anim.anticipate_interpolator));

            break;
        case 4:
            animation.setInterpolator(AnimationUtils.loadInterpolator(this, android.R.anim.overshoot_interpolator));

            break;
        case 5:
            animation.setInterpolator(AnimationUtils.loadInterpolator(this, android.R.anim.anticipate_overshoot_interpolator));

            break;
        case 6:
            animation.setInterpolator(AnimationUtils.loadInterpolator(this, android.R.anim.bounce_interpolator));

            break;

        }
        target.startAnimation(animation);


    }



    @Override
    public void onNothingSelected(AdapterView<?> arg0) {



    }
}
