Android导航抽屉显示2个片段

Question

So I'm working on an android app that needs to show 2 fragments side by side and still have the option to use a navigation drawer like this Image link can't post images :(

My problem is that when I'm trying to add any fragments into the xml file I'm getting the following error

  06-17 12:18:14.384    2377-2377/com.example.evemanufacturing3.app E/Trace﹕ error opening trace file: No such file or directory (2)

</android.support.v4.widget.DrawerLayout>

and my MainActivity lookes like this

move to like becouse off size restriction

past bin link code to version 1 off MainActity moved

i been trying to change to the activity to extend fragmentActivity instead off activity witch didt work :( i also been trying to move the 2 fragments in to a different xml file and setting the content to the new xml didn't work :( maybe me making some stupid error I'm really bad at android layout :(

My app works fine if i only add fragments from MainActivity but then dos not show the second fragment... the second I'm adding the fragments to the xml code my app crashes on start

EDIT

still no progress :( i been traying to change the layout a bit and even setting a totaly new layout file and still traying to keep the navigation drawer but still getting the same creash errors :(

any idears??

EDIT 2 force me to remove first version off MainActivity becouse off size restrictions

so i been googling some more after a replay. i changed all imports to be

android.support.v4.app.

witch didt make any difference so i trayed running a debugger to see what linje the app failed at the line was

setContentView(R.layout.drawfragment);

so that made me think that i might cut change the setcontent to anothere xml contaning a relativ layout and 2 fragments gives the same error so i trayed removing the 2 fragments witch gave me an error men traying to create the navigation drawer.

any one have a solution to this problem ?? ore due i need some diffrent way off creating the navigation drawer?

new MainActivity lookes like this alot off the off topic have changed but not much diffrence in the topic related code

Answer 1

Try using only support library imports. Because navigation drawer is only in support library, you cant call import android.app.Fragment;

import android.support.v4.app.Fragment;

Make also other imports from support Library . In Eclipse, delete them, then press Crtl+Shift+o and then choose supportlibrary imports.

I hope this helps :)

EDIT1:

Try to remove

 tools:layout="@layout/fragment_navigation_drawer"

And one performance suggestion, you dont have to use <FrameLayout> , just use <RelativeLayout> .

EDIT2: For the first fragment set

android:id="@+id/fe1"
android:layout_toRightOf="@+id/fe2"

for the second

android:id="@id/fe2"

For the drawer view you have to specify horizontal gravity

•The drawer view must specify its horizontal gravity with the android:layout_gravity attribute. To support right-to-left (RTL) languages, specify the value with "start" instead of "left" (so the drawer appears on the right when the layout is RTL).

which means in your third fragment:

<!-- The navigation drawer -->
<fragment
   android:id="@+id/left_drawer"
   android:layout_gravity="start"
   ...
/>

I apologize for my English, if something isnt clear, just tell me ;-)
