Android动画一

Android动画的两种形式

 

布局文件

 

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"

    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"

    android:paddingRight="@dimen/activity_horizontal_margin"

    android:paddingTop="@dimen/activity_vertical_margin"

    android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">



    <ImageView

        android:layout_width="40dp"

        android:layout_height="40dp"

        android:id="@+id/imageView"

        android:onClick="click"

        android:src="@android:drawable/ic_lock_idle_alarm" />



    <Button

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:text="move"

        android:onClick="move"

        android:id="@+id/button"

        android:layout_alignParentBottom="true"

        android:layout_centerHorizontal="true"

        android:layout_marginBottom="102dp" />



</RelativeLayout>

 

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();

完整的代码：

package com.androidbase.zjn.androidbase;



import android.animation.AnimatorSet;

import android.animation.ObjectAnimator;

import android.animation.PropertyValuesHolder;

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只是简单的移动

//        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



//        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();



//        上面的优化

//        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.playSequentially(animator1,animator2,animator3);//按照顺序动画

        set.play(animator1).with(animator2).before(animator3);//动画1和动画2一块进行，让后再进行动画3

        set.setDuration(1000);

        set.start();



    }
