我接受了以下错误：
The method getSupportFragmentManager() is undefined for the type new AdapterView.OnItemClickListener(){}
以下行： FragmentManager fragmentManager = getSupportFragmentManager（）;
以下是整个活动代码：

});

mDrawerLayout.setDrawerListener(mDrawerToggle);
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main_activity_actions, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
switch (item.getItemId()) {
case R.id.action_settings:
Toast.makeText(this, "Settings", Toast.LENGTH_SHORT).show();
;
break;
default:
return super.onOptionsItemSelected(item);
}
return true;
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
}
首先，该类正在扩展ActionBarActivity，但我在Android 4.42上运行并且首选使用活动。
如果有人可以帮助我，那将会有所帮助。
如果您需要任何澄清，请告诉我。

我相信错误发生在以下几行：
mDrawerList.setAdapter(new ArrayAdapter<String>(getActionBar()
.getThemedContext(), android.R.layout.simple_list_item_1,
mOptionMenu));
答案 0 :(得分：6)
Activity类没有getSupportFragmentManager()方法。相反，请将您的活动扩展为FragmentActivity。
