    mAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, Array);
    mDrawerList.setAdapter(mAdapter);

    mDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {

我在一个单独的项目中创造了谷歌地图工作的罚款。当我把它放在我的项目，它总是停每次我选择跟踪我的时间在我的抽屉式导航栏。我不知道什么是错我的code或所欠缺在我的code。

I am working fine in a separate project in creating the google map. When I put it to my project it always stopped every time I choose the track me in my navigation drawer. I don't know what is wrong with my code or what is lacking in my code.

推荐答案

扩展您的Mapfragemnt作为Fragemnt ..不作为FragmentActivity ...

Extend your Mapfragemnt as Fragemnt.. Not as FragmentActivity...

然后在你的主要活动，请拨打下方code ...

Then in your main activity, call the below code...

FragmentManager fragmentManager = getSupportFragmentManager();
            FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
            fragmentTransaction.replace(R.id.content_frame, MapActivity());
            fragmentTransaction.commit();

R.id.content_frame是里面的FrameLayout您MainActivity.xml ...

R.id.content_frame is the framelayout inside your MainActivity.xml...

我不知道什么是你给它的，因为的FrameLayout你没有张贴MainActivity.xml的ID

I dont know what is the id you gave it to that framelayout since you didnt post the MainActivity.xml
