Android点赞动画效果 ，点赞后加一，2种方法，①补间动画②位移动画

第一个动画文件btn_anim.xml

<?xml version="1.0" encoding="utf-8"?>

<set
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/decelerate_interpolator">
<!--位移动画    -->
    <translate
        android:fromXDelta="0.0"
        android:fromYDelta="0.0"
        android:toXDelta="0.0"
        android:toYDelta="-75.0"
        android:duration="750"
        android:fillBefore="true"
        android:fillAfter="true" />

<!--缩放动画    -->
<scale        android:fromXScale="1.0"        android:fromYScale="1.0"        android:toXScale="1.05"        android:toYScale="1.0"        android:pivotX="50%"        android:pivotY="50%"        android:duration="350"        android:fillBefore="true"        android:fillAfter="true"/></set>

2-在res文件夹 anim文件夹下面，建立第二个文件layout_anim.xml):

<?xml version="1.0" encoding="utf-8"?>

<set
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/decelerate_interpolator">

    <scale
        android:fromXScale="1.0"
        android:fromYScale="1.0"
        android:toXScale="0.95"
        android:toYScale="0.95"
        android:pivotX="50%"
        android:pivotY="50%"
        android:duration="100"
        android:fillBefore="true"
        android:fillAfter="true"/>

</set>

3主activity 我是在fragment中使用，你就随意吧。

...
private ScrollView scrollView; // This is my container. Yours may be different
private Animation btnAnim;
private Animation layoutAnim;
...

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        // Getting context
        context = getActivity().getApplicationContext();

        btnAnim = AnimationUtils.loadAnimation(context, R.anim.btn_anim);
        btnAnim.setAnimationListener(new Animation.AnimationListener() {
            @Override
            public void onAnimationStart(Animation animation) {

            }

            @Override
            public void onAnimationEnd(Animation animation) {
                layoutAnim = AnimationUtils.loadAnimation(context, R.anim.layout_anim);
                scrollView.startAnimation(layoutAnim);
            }

            @Override
            public void onAnimationRepeat(Animation animation) {

            }
        });

        // create view
        View view = inflater.inflate(R.layout.fragment_browse_single, container, false);

        scrollView = (ScrollView) view.findViewById(R.id.scrollView);

        myButton = (Button) view.findViewById(R.id.myButton);
        myButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                btnZan.startAnimation(btnAnim);
            }
        });

        Log.i(TAG, "View created");
        return view;
    }

另一种demo做法。试用了线程。不推荐使用

public class applaudAnimation extends Activity implements OnClickListener
 {

 

    private Button
 button;

    private TextView
 textView;

    private android.view.animation.Animation
 animation;

 

    public void onCreate(Bundle
 savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.animation);

 

        animation
 = AnimationUtils.loadAnimation(this,R.anim.applaud_animation);

        button
 = (Button) findViewById(R.id.bt);

        button.setOnClickListener(this);

        textView
 = (TextView) findViewById(R.id.animation);

    }

 

    @Override

    public void onClick(View
 v) {

        if (v
 == button) {

            textView.setVisibility(View.VISIBLE);

            textView.startAnimation(animation);

            new Handler().postDelayed(new Runnable()
 {

                public void run()
 {

                    textView.setVisibility(View.GONE);

                }

            }, 1000);

        }

 

    }

}





animation.xml





<?xml
 version="1.0" encoding="utf-8"?>
