代码文件:
package com.androidbase.zjn.androidbase; import android.support.v7.app.ActionBarActivity; import android.os.Bundle; import android.view.View; import android.view.animation.TranslateAnimation; import android.widget.ImageView; import android.widget.Toast; public class MainActivity extends ActionBarActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } public void click(View view){ Toast.makeText(this,"clicked",Toast.LENGTH_LONG).show(); } public void move(View view){ TranslateAnimation animation = new TranslateAnimation(0,200,0,0); animation.setDuration(1000);//运动1秒钟 animation.setFillAfter(true);//动画结束后果停留到原来的位置 ImageView imageView =(ImageView) findViewById(R.id.imageView); imageView.startAnimation(animation);//imageView绑定动画 } }
使用Animator的效果:
ImageView imageView =(ImageView) findViewById(R.id.imageView); ObjectAnimator.ofFloat(imageView,"translationX",0,200F).setDuration(1000).start(); ObjectAnimator.ofFloat(imageView,"translationY",0,200F).setDuration(1000).start(); ObjectAnimator.ofFloat(imageView,"rotation",0,360F).setDuration(1000).start();
使用几个一起懂:
ImageView imageView =(ImageView) findViewById(R.id.imageView); PropertyValuesHolder p1 = PropertyValuesHolder.ofFloat("rotation",0,360F); PropertyValuesHolder p2 = PropertyValuesHolder.ofFloat("translationX",0,200F); PropertyValuesHolder p3 = PropertyValuesHolder.ofFloat("translationY",0,200F); ObjectAnimator.ofPropertyValuesHolder(imageView,p1,p2,p3).setDuration(1000).start();
//几个动画一起显示 ImageView imageView =(ImageView) findViewById(R.id.imageView); ObjectAnimator animator1=ObjectAnimator.ofFloat(imageView,"translationX",0,200F); ObjectAnimator animator2=ObjectAnimator.ofFloat(imageView,"translationY",0,200F); ObjectAnimator animator3=ObjectAnimator.ofFloat(imageView,"rotation",0,360F); AnimatorSet set = new AnimatorSet(); set.playTogether(animator1,animator2,animator3); set.setDuration(1000); set.start();
