在Android應用程序的Gallery中選擇圖像：“ release（）之后調用的方法”

Question

我試圖從我的android應用程序的Gallery中選擇圖像，但之后出現錯誤消息：

例外情況：

java.lang.RuntimeException: Method called after release()

代碼：

public class ProductAfter extends Fragment{
......

    Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);

            photoPickerIntent.setType("image/*");
            startActivityForResult(photoPickerIntent, 1);

......
}

Answer 1

First Step :

You have to @Override this method to catch the call back from the Gallery to Fragment

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

    // Check with your Request code and do stuff with that 
}

Second Step:

 From the Gallery the call back will be directly to the Parent Activity, So you have to  @Override  the same method in the parent Activity 

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);


   // here check for all the fragments where the method is overidden and callback reaches there 
        for (Fragment fragment : getSupportFragmentManager().getFragments()) {
            if (fragment != null)
                fragment.onActivityResult(requestCode, resultCode, data);
        }
    }
    }

希望這能解決您的問題

在TabsPagerAdapter中：

 @Override
    public Fragment getItem(int index) {


        switch (index) {

        case 0:
            // Games fragment activity
            return new CategorieFragment();
        case 1:
            // Movies fragment activity
            return new ProductBefore();         
        case 2:

            return new ProductAfter();

        case 3:
            // Top Rated fragment activity
            return new CodeBarreAuto();



        }

        return null;
    }

當我更改數字案例->案例1的案例2和案例2的案例1時，它就可以了！
