导航抽屉AppCompat和正常的动作条​​?

问题描述:

我有目前,导航抽屉,一个动作条(无工具栏),并在我的风格定义为母 Theme.AppCompat.Light 。我想留在动作条,但是当我使用的父母,我成为了以下错误:

I have currently, a navigation drawer, a actionbar(no toolbar), and in the styles i defined as parent Theme.AppCompat.Light. I want to stay at actionbar, but when i use that parent, i become the following error:

"Attempt to invoke virtual method 'android.content.Context android.app.ActionBar.getThemedContext()' on a null object reference"

在code:

in that code:

mDrawerListView.setAdapter(new ArrayAdapter<String>(
            getActionBar().getThemedContext(),
            R.layout.navdrawer_item_row,
            android.R.id.text1,
            new String[]{
                    getString(R.string.title_section1),
                    getString(R.string.title_section2),
                    getString(R.string.title_section3),
            }));

有一个人解决的建议来解决? 在此先感谢

Have anyone a solve suggestion to fix? Thanks in advance

您需要使用 getSupportActionBar()而不是 getActionBar()。更改您的code这一切的发生。

You need to use getSupportActionBar() instead of getActionBar(). Change all occurrences of this in your code.

下面是更正后的code:

Below is the corrected code:

   ActionBar ab = getSupportActionBar();
   mDrawerListView.setAdapter(new ArrayAdapter<String>(
        ab.getThemedContext(),
        R.layout.navdrawer_item_row,
        android.R.id.text1,
        new String[]{
                getString(R.string.title_section1),
                getString(R.string.title_section2),
                getString(R.string.title_section3),
        }));

不要忘了导入 android.support.v7.app.ActionBar

另外,在风格父改为 Theme.AppCompat.Light.DarkActionBar
