属性动画缩放的util

自己留存，以防止忘记：

值得注意的是objectAnimator可以放多个参数

public class ScaleUtils {
    public static void getScaleAnimator(View view){
        AnimatorSet set = new AnimatorSet();
        ObjectAnimator scaleX = ObjectAnimator.ofFloat(view,"ScaleX",1.5f,1.2f,0.8f,1.0f);
        ObjectAnimator scaleY = ObjectAnimator.ofFloat(view,"ScaleY",1.5f,1.2f,0.8f,1.0f);
        set.playTogether(scaleX,scaleY);
        set.setDuration(500);
        set.start();
    }
}

使用方式：点击一下textview伸缩，

public class MainActivity extends AppCompatActivity implements View.OnClickListener{
    private TextView tv_name;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tv_name = (TextView) findViewById(R.id.tv_name);
        tv_name.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()){
            case R.id.tv_name:
                DemoUtils.getScaleAnimator(tv_name);
                break;

        }
    }
}
