Android 单击时文本视图和图像视图不更改

我有一个活动，其中有三个片段放在一个ViewPager中。在前两个片段中，我有一个下拉列表，有点像一个动画ExpandableListView，但它是一个简单的RelativeLayout，包含一个TextView和ImageView，当按下该按钮时，会向下滑动包含一些元素的线性布局。单击RelativeLayout后，将执行以下操作：

更改单击的RelativeLayout的背景色（每次适用于每个片段中的每个布局）

在TextView中更改文本的颜色（每次都适用于我将在下面解释的第一个元素）

设置图像动画，一个用于更改颜色和旋转的箭头（除第一个元素外也适用）

问题如下： 第一个片段只包含一个列表（显示或隐藏LinearLayout的RelativeLayout），它可以很好地处理背景、文本颜色和图像更改，图像旋转，LinearLayout相应地上下滑动。第二个片段包含4个这样的分组（RelativeLayout控制LinearLayout），第一次显示该片段时，似乎只有第一个分组起作用。其他三个改变背景并滑动线性布局，但据我所知，它保持相同的颜色和相同的图像（有两种颜色，一种是白色，一种是橙色，由于背景从橙色变为白色，我假设文本保持白色而不是变为橙色，图像也是如此）。

笑点： 当我离开它几秒钟并再次单击它时，它工作正常，一切都会相应地改变，例如，如果我翻转到第三个片段并返回到第二个片段，它就会工作。另一方面，如果我启动应用程序，进入第二个片段，回到第一个片段，再回到第二个片段，它就不工作了。

我不知道这是否与GC和回收视图或其他方面有关。

更新

在扩展了

fragment

的my fragment类和

OnPageChangeListener

的方法

onPageSelected（）

上运行日志，表明标记设置正确且可见。这个问题似乎与片段的生命周期有关，因为文本和图像的更改只有在我翻阅所有三个片段，然后返回到第二个片段时才会发生

设置寻呼机：

List<Fragment> fragments = getFragments();
pageAdapter = new NutritionPageAdapter(getSupportFragmentManager(),
    fragments);
ViewPager pager = (ViewPager) findViewById(R.id.viewpager);
pager.setAdapter(pageAdapter);

尝试运行日志或调试断点以检查您的viewTag是否按预期设置？@zgc7009我运行了一个日志，当第二个布局膨胀时，标记是否按预期设置。我试图通过使用ID绕过所有标记，但错误仍然存在。

public static final String FRAGMENT_TITLE = "FRAGMENT_TITLE";
    private View v;

    public static final NutritionFragment newInstance(String string) {
        NutritionFragment f = new NutritionFragment();
        Bundle b = new Bundle(1);
        b.putString(FRAGMENT_TITLE, string);
        f.setArguments(b);

        return f;

    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        String screen = getArguments().getString(FRAGMENT_TITLE);
        if (screen.equals("Menu")) {
            v = inflater.inflate(R.layout.nutrition_menu_activity_layout,
                    container, false);
        } else if (screen.equals("Transition")) {
            v = inflater.inflate(R.layout.nutrition_transition_activity_layout,
                    container, false);
        } else {
            v = inflater.inflate(R.layout.nutrition_nutrition_activity_layout,
                    container, false);
        }

        return v;
