Question

我用Actionbar创建了一个Demoapplication。在NavDrawer中，有2个Elements，它们加载不同的Fragment。如果我尝试加载。 Support.getFAQFragment（...），出现以下错误：

任何想法，为什么会这样？

我还补充道 -keep class android.support.v4。 {*; } ** 到proguard文件。

我不知道如何找到任何解决方案。

代码：

final HashMap config = new HashMap();
    config.put("toolbarId", R.id.toolbar);
    try {
        mDrawerLayout.postDelayed(new Runnable() {
            @Override
            public void run() {

                FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
                try {
                    ft.replace(R.id.content_frame, Support.getFAQsFragment(MainActivity.this, config)).commitAllowingStateLoss();
                } catch(IllegalStateException ex) {
                    // activity already destroyed
                }
            }
        }, 300);

    } catch (Exception ex) {
        ex.printStackTrace();
        return;
    }
    mDrawerLayout.closeDrawers();

Answer 1

这主要发生在Helpshift片段未获得所需主题元素的情况下。确保包含Helpshift活动的Activity的父主题为@style/Helpshift.Theme.Activity。确保您已按照步骤4＆amp; 5 here。

如果我尝试加载Helpshift片段，则会出现Inflateexception
