Question

我创建了一个应用程序，它使用了antonyt的InfiniteViewpager。

我想在创建视图时在Imageview上添加动画，但我的动画工作了几次，并非总是如此。这是代码：

public class ColourFragment extends Fragment {


private int identifier;
private String logo;




@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle args = getArguments();

identifier = args.getInt("identifier");
logo = args.getString("logo");
}

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

    View V = inflater.inflate(R.layout.radiologok, container, false);

ImageView我要制作动画。

    ImageView imageView = (ImageView)V.findViewById(R.id.radiologovalaszto); 


    ProgressBar progressBar = (ProgressBar) V.findViewById(R.id.progressBar1);

    DisplayMetrics displaymetrics = new DisplayMetrics();
    getActivity().getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
    int height = displaymetrics.heightPixels / 4 * 3;
    int width = displaymetrics.widthPixels / 4 * 3;  


    imageView.setAdjustViewBounds(true);
    imageView.getLayoutParams().height = height;
    imageView.getLayoutParams().width = width;

加载Android查询库以从网络获取图像。

   AQuery aq = new AQuery(getActivity());
   AQUtility.setDebug(true);
   aq.hardwareAccelerated11();

图像已设定。

aq.id(imageView).progress(progressBar).image(logo, true, true, width, 0);

我想添加Animation

    Animation pulse = AnimationUtils.loadAnimation(getActivity(), R.anim.pulse);
imageView.startAnimation(pulse);

    Return V;

}

这是我的动画：

<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false" >
<scale
    android:duration="1000"
    android:fromXScale="1"
    android:fromYScale="1"
    android:pivotX="50%"
    android:pivotY="50%"
    android:toXScale="0.5"
    android:toYScale="0.5" />
<scale
    android:duration="1000"
    android:fromXScale="1"
    android:fromYScale="1"
    android:pivotX="50%"
    android:pivotY="50%"
    android:startOffset="1000"
    android:toXScale="2"
    android:toYScale="2" />
   </set>

我使用fragmentadapter加载视图：

 final PagerAdapter adapter = new FragmentPagerAdapter(getSupportFragmentManager()) {

                @Override
                public int getCount() {
                return Radiologos.length;
                }

                @Override
                public Fragment getItem(int position) {
                Fragment fragment = new ColourFragment();
                Bundle args = new Bundle();

                args.putString("logo", Radiologos[position]);
                args.putInt("identifier", position);
                fragment.setArguments(args);
                return fragment;
                }
            };

尝试这件事，它可能会起作用

1st 创建一个包含一些静态变量的类，以便我们以后可以使用它

<强> StaticVariables.java

public static ArrayList<ImageView> listOfImageViews = new ArrayList<ImageView>();

第二次现在正常onCreateView创建imageview，现在将其传递给我们刚刚创建的静态变量

imageView.setAdjustViewBounds(true);
imageView.getLayoutParams().height = height;
imageView.getLayoutParams().width = width;
....
StaticVariable.listOfImageViews.add(imageview);

3rd 现在在视图分页器上，您的使用添加了一个pageListener并在onPageSelected上添加动画imageview并启动动画

mPager.setOnPageChangeListener(new OnPageChangeListener() {

        @Override
        public void onPageSelected(int arg0) {
            Log.d(LOG_TAG, "onPageSelected  " + arg0);
            //Create your animation
            Animation pulse = AnimationUtils.loadAnimation(getActivity(), R.anim.pulse);
            //Start your animation
            StaticVariable.listOfImageViews.get(arg0).startAnimation(pulse);
        }

        @Override
        public void onPageScrolled(int arg0, float arg1, int arg2) {}

        @Override
        public void onPageScrollStateChanged(int arg0) {}
    });
