问题描述

我一直在尝试遵循android 翻转卡教程。按照指示，我创建了四个自定义动画集



card_flip_right_in.xml： 

 < set xmlns：android =http://schemas.android.com/apk/res/android> 
  android：valueFrom =1.0
 android：valueTo =0.0
 android：propertyName =alpha
 android：duration =0 /> 
 
  android：valueFrom =180
 android：valueTo =0
 android：propertyName =rotationY
 android： interpolator =@ android：interpolator / accelerate_decelerate
 android：duration =300/> 
 
  android：valueFrom =0.0
 android：valueTo =1.0
 android：propertyName =alpha
 android： startOffset =150
 android：duration =1/> 
< / set>

card_flip_right_out.xml： 

 < set xmlns：android =http://schemas.android.com/apk/res/android> 
  android：valueFrom =0
 android：valueTo = -  180
 android：propertyName =rotationY
 android：interpolator = @android：interpolator / accelerate_decelerate
 android：duration =300/> 
 
  android：valueFrom =1.0
 android：valueTo =0.0
 android：propertyName =alpha
 android： startOffset =150
 android：duration =1/> 
< / set> b 
 
 
 $ b 
 > < set xmlns：android =http://schemas.android.com/apk/res/android> 
 
  android：valueFrom =1.0
 android：valueTo =0.0
 android：propertyName =alpha
 android： duration =0/> 
 
< objectAnimator 
 android：valueFrom = -  180
 android：valueTo =0
 android：propertyName =rotationY
 android ：interpolator =@ android：interpolator / accelerate_decelerate
 android：duration =300/> 
 
  android：valueFrom =0.0
 android：valueTo =1.0
 android：propertyName =alpha
 android： startOffset =150
 android：duration =1/> 
< / set> b 
 
 
 $ b 
 > < set xmlns：android =http://schemas.android.com/apk/res/android> 
  android：valueFrom =0
 android：valueTo =180
 android：propertyName =rotationY
 android：interpolator =@ android：interpolator / accelerate_decelerate
 android：duration =300/> 
 
  android：valueFrom =1.0
 android：valueTo =0.0
 android：propertyName =alpha
 android： startOffset =150
 android：duration =1/> 
< / set>

而且，我在片段中提供了这个：

  public class ContestantInfoFragment extends Fragment {
 
 private context context; 
 
私人字符串cName，cCountry，cDesc; 
 
私人TextView contestant_name，contestant_country，contestant_desc; 
私人ImageButton flip_btn; 
 
 public ContestantInfoFragment（）{
} 
 $ b $ @覆盖
 public View onCreateView（LayoutInflater inflater，ViewGroup容器，
 Bundled savedInstanceState）{ 
 
查看v = inflater.inflate（R.layout.fragment_contestant_info，container，false）; 
 
 context = inflater.getContext（）; 
 
 Bundle bundle = this.getArguments（）; 
 if（bundle！= null）{
 cName = bundle.getString（NAME，Problem loading contestant's name）; 
 cCountry = bundle.getString（COUNTRY，Problem loading contestant's country）; 
 cDesc = bundle.getString（DESC，问题加载参赛者的描述）; 
 
 contestant_name =（TextView）v.findViewById（R.id.contestant_name）; 
 contestant_country =（TextView）v.findViewById（R.id.contestant_country）; 
 contestant_desc =（TextView）v.findViewById（R.id.contestant_desc）; 
 
 contestant_name.setText（cName）; 
 contestant_country.setText（cCountry）; 
 contestant_desc.setText（cDesc）; 
} 
 
 flip_btn =（ImageButton）v.findViewById（R.id.contestant_flip_btn）; 
 flip_btn.setOnClickListener（new View.OnClickListener（）{
 @Override 
 public void onClick（View v）{
 getActivity（）。getSupportFragmentManager（）
 .beginTransaction （）
 .setCustomAnimations（R.animator.card_flip_right_in，R.animator.card_flip_right_out，
 R.animator.card_flip_left_in，R.animator.card_flip_left_out）
 .replace（R.id.mainContent，新的ContestantsFragment（））
 .addToBackStack（null）
 .commit（）; 
} 
}）; 
 
 return v; 
}

}

但是，使用 

  .setCustomAnimations（R.animator.card_flip_right_in，R.animator。 card_flip_right_out，
 R.animator.card_flip_left_in，R.animator.card_flip_left_out）

反馈I得到的是期望资源的类型anim
任何人有任何想法，为什么这不起作用？

>根本原因：



Google的示例使用 getFragmentManager（），我们合理的程序员试图使用 getSupportFragmentManager（）。

不幸的是， getSupportFragmentManager（）。setCustomAnimations（）签名是不同的。
此外， objectAnimator 不兼容 getSupportFragmentManager（）。setCustomAnimations（）



总之， Google创建了一个无用的卡片翻转演示。如果你四处搜索，你会发现很多人都遇到了同样的问题。





解决方案：使用带有NineOldAndroids的Android支持库v4库

当然，Google的支持库需要支持暴露功能。 LOL


I've been trying to follow the android flip card tutorial. As instructed, I created four custom animator sets

card_flip_right_in.xml:

<set xmlns:android="http://schemas.android.com/apk/res/android">
<objectAnimator
    android:valueFrom="1.0"
    android:valueTo="0.0"
    android:propertyName="alpha"
    android:duration="0" />

<objectAnimator
    android:valueFrom="180"
    android:valueTo="0"
    android:propertyName="rotationY"
    android:interpolator="@android:interpolator/accelerate_decelerate"
    android:duration="300" />

<objectAnimator
    android:valueFrom="0.0"
    android:valueTo="1.0"
    android:propertyName="alpha"
    android:startOffset="150"
    android:duration="1" />
</set>

card_flip_right_out.xml:

<set xmlns:android="http://schemas.android.com/apk/res/android">
<objectAnimator
    android:valueFrom="0"
    android:valueTo="-180"
    android:propertyName="rotationY"
    android:interpolator="@android:interpolator/accelerate_decelerate"
    android:duration="300" />

<objectAnimator
    android:valueFrom="1.0"
    android:valueTo="0.0"
    android:propertyName="alpha"
    android:startOffset="150"
    android:duration="1" />
</set>

card_flip_left_in.xml:

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

<objectAnimator
    android:valueFrom="1.0"
    android:valueTo="0.0"
    android:propertyName="alpha"
    android:duration="0" />

<objectAnimator
    android:valueFrom="-180"
    android:valueTo="0"
    android:propertyName="rotationY"
    android:interpolator="@android:interpolator/accelerate_decelerate"
    android:duration="300" />

<objectAnimator
    android:valueFrom="0.0"
    android:valueTo="1.0"
    android:propertyName="alpha"
    android:startOffset="150"
    android:duration="1" />
</set>

card_flip_left_out.xml:

<set xmlns:android="http://schemas.android.com/apk/res/android">
<objectAnimator
    android:valueFrom="0"
    android:valueTo="180"
    android:propertyName="rotationY"
    android:interpolator="@android:interpolator/accelerate_decelerate"
    android:duration="300" />

<objectAnimator
    android:valueFrom="1.0"
    android:valueTo="0.0"
    android:propertyName="alpha"
    android:startOffset="150"
    android:duration="1" />
</set>

And, I have this in my fragment:

public class ContestantInfoFragment extends Fragment {

private Context context;

private String cName, cCountry, cDesc;

private TextView contestant_name, contestant_country, contestant_desc;
private ImageButton flip_btn;

public ContestantInfoFragment() {
}

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

    View v = inflater.inflate(R.layout.fragment_contestant_info, container, false);

    context = inflater.getContext();

    Bundle bundle = this.getArguments();
    if(bundle != null) {
        cName = bundle.getString("NAME", "Problem loading contestant's name");
        cCountry = bundle.getString("COUNTRY", "Problem loading contestant's country");
        cDesc = bundle.getString("DESC", "Problem loading contestant's description");

        contestant_name = (TextView) v.findViewById(R.id.contestant_name);
        contestant_country = (TextView) v.findViewById(R.id.contestant_country);
        contestant_desc = (TextView) v.findViewById(R.id.contestant_desc);

        contestant_name.setText(cName);
        contestant_country.setText(cCountry);
        contestant_desc.setText(cDesc);
    }

    flip_btn = (ImageButton) v.findViewById(R.id.contestant_flip_btn);
    flip_btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            getActivity().getSupportFragmentManager()
                    .beginTransaction()
                    .setCustomAnimations(R.animator.card_flip_right_in, R.animator.card_flip_right_out,
                                         R.animator.card_flip_left_in, R.animator.card_flip_left_out)
                    .replace(R.id.mainContent, new ContestantsFragment())
                                    .addToBackStack(null)
                                    .commit();
        }
    });

    return v;
}

}

However, I got syntax errors (red zip lines) for using

.setCustomAnimations(R.animator.card_flip_right_in, R.animator.card_flip_right_out,
                                         R.animator.card_flip_left_in, R.animator.card_flip_left_out)

The feedback I got was "Expected resource of type anim" Anyone has any idea why this is not working?

解决方案

root cause:

Google's example uses getFragmentManager() and we sensible programmers are trying to use getSupportFragmentManager().

Unfortunately, getSupportFragmentManager().setCustomAnimations() signature is different. Additionally, objectAnimator is incompatible with getSupportFragmentManager().setCustomAnimations()

In short, Google created a useless card-flip demo. If you search around, you'll see that a lot of people have encountered the same problem.

solution: use of "Android Support Library v4 with NineOldAndroids" library https://stackoverflow.com/a/18511350/550471

of course it makes sense that Google's support library needs support with exposing functionality. LOL
