- by guillaume
I'm trying to use le lib SlidingMenu in my app but i'm having some problems.
I'm getting this error:
11-04 15:50:46.225: E/FragmentManager(21112): No view found for id

super.onCreate(savedInstanceState);
setTitle(mTitleRes);
// set the Behind View
setBehindContentView(R.layout.menu_frame);
if (savedInstanceState == null) {
FragmentTransaction t = this.getSupportFragmentManager().beginTransaction();
mFrag = new SampleListFragment();
t.replace(R.id.menu_frame, mFrag);
t.commit();
} else {
mFrag = (ListFragment) this.getSupportFragmentManager().findFragmentById(R.id.menu_frame);

MainActivity.java
package com.myapp;

import android.widget.ListView;
public class MainActivity extends BaseActivity {
public MainActivity(){
super(R.string.app_name);
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final ListView listview = (ListView) findViewById(R.id.listview_tweets);
DatabaseHelper db = new DatabaseHelper(this);
ArrayList<Tweet> tweets = db.getAllTweets();
TweetListViewAdapter adapter = new TweetListViewAdapter(this, R.layout.listview_item_row, tweets);
listview.setAdapter(adapter);
setSlidingActionBarEnabled(false);
}
}
I don't understand why the view menu_frame is not found because I have a view with the id menu_frame and this view is a child of the layout menu_frame.
