android:id="@+id/menu">
</fragment>
and this is MenuFragment.java
import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import com.chenjiayao.news.R;
import java.util.ArrayList;
public class MenuFragment extends Fragment {
private View view;

}
@Override
public void onActivityCreated(Bundle savedInstanceState) {

super.onActivityCreated(savedInstanceState);
ListView listView = (ListView) view.findViewById(R.id.lv);
ArrayAdapter<String> adapter = new ArrayAdapter<>(getActivity(),
android.R.layout.simple_list_item_1, android.R.id.text1,
initData());
listView.setAdapter(adapter);
}
private ArrayList<String> initData() {
ArrayList<String> list = new ArrayList<>();
list.add("fragment1");
list.add("fragment2");
list.add("fragment3");
list.add("fragment4");
list.add("fragment5");
return list;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
view = LayoutInflater.from(getActivity()).inflate(R.layout.list_view,
null);
return view;
}
}
last,is MainActivity.java file
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import com.jeremyfeinstein.slidingmenu.lib.app.SlidingFragmentActivity;
public class MainActivity extends SlidingFragmentActivity{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
initSlidingMenu();
}
private void initSlidingMenu() {
setBehindContentView(R.layout.menu);
setContentView(R.layout.activity_main);
SlidingMenu sm = getSlidingMenu();
sm.setShadowWidthRes(R.dimen.shadow_width);
sm.setShadowDrawable(R.drawable.shadow);
sm.setBehindOffsetRes(R.dimen.slidingmenu_offset);
sm.setFadeDegree(0.35f);
sm.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);
sm.setBehindScrollScale(0.0f);
MenuFragment menuFragment = new MenuFragment();
getFragmentManager().beginTransaction()
.replace(R.id.menu, menuFragment, "Menu").commit();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
I know problem maybe happen in setBehindContentView(R.layout.menu);,but I don't how to fix it,and more strange is I can run application well in Eclipse.Is wrong way to import SlidingMenu in android studio ? I hope someone can help me fix this problem. th
