Hi I have a sliding tab layout with several tabs, each tab contains a list view with several items. When the user clicks a lv item i need to load a different fragment (each lv item has a corresponding fragment with several controls). I managed to load a fragment by inserting a dummy fragment in main activity layout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"; xmlns:tools="http://schemas.android.com/tools"; android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context=".MainActivity" android:id="@+id/main_activity" > <include android:id="@+id/tool_bar" layout="@layout/tool_bar" android:layout_height="wrap_content" android:layout_width="match_parent" /> <com.grozeaion.www.gvicameraremotecontrol.SlidingTabLayout android:id="@+id/tabs" android:layout_width="match_parent" android:layout_height="wrap_content" android:elevation="2dp" android:background="@color/ColorPrimary" android:layout_below="@+id/tool_bar"/> <android.support.v4.view.ViewPager android:id="@+id/pager" android:layout_height="match_parent" android:layout_width="300dp" android:layout_weight="1" android:background="#bde354" android:layout_below="@+id/tabs"> </android.support.v4.view.ViewPager> <fragment android:layout_width="match_parent" android:layout_height="fill_parent" android:name="com.grozeaion.www.gvicameraremotecontrol.dummy" android:id="@+id/dummy" tools:layout="@layout/fragment_dummy" android:layout_alignTop="@+id/pager" android:layout_toRightOf="@+id/pager" android:layout_alignParentBottom="true" android:layout_alignParentEnd="true" /> </RelativeLayout > the list views are populated in class Tab_modes, also here i am trying to replace the dummy fragment. When the app is started the public void onCreate(Bundle savedInstanceState) is called twice and i end up on the first tab with the fragment thet corresponds to second tab lv item ft.replace(R.id.dummy, ModeTriggered.newInstance("Triggered")).commit(); package com.grozeaion.www.gvicameraremotecontrol; import android.app.Activity; import android.app.Fragment; import android.os.Bundle; import android.support.v4.app.FragmentTransaction; import android.support.v4.app.ListFragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.AdapterView; import android.widget.Toast; import java.util.ArrayList; /** * Created by John on 6/12/2015. */ public class Tab_Modes extends ListFragment implements AdapterView.OnItemClickListener { private ArrayList<NameImg> items = new ArrayList<NameImg>(); private int crtMode; private FragmentTransaction ft; public static final Tab_Modes newInstance(int myInt) { Tab_Modes f = new Tab_Modes(); Bundle arguments = new Bundle(); arguments.putInt("position", myInt); f.setArguments(arguments); return f; } @Override public void onAttach(Activity activity) { super.onAttach(activity); } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Bundle arguments = getArguments(); crtMode = arguments.getInt("position"); items.clear(); ft = getFragmentManager().beginTransaction(); //Frag2 fragmentObj=(Frag2) geFragmentManager().findFragmentById(R.id.pager); //int crtF = findFragmentById(R.id.pager); switch (crtMode) { case 0: items.add(new NameImg("Manual", "Simple camera Control", R.drawable.hand)); items.add(new NameImg("Bulb", "Long Exposure", R.drawable.bulb)); items.add(new NameImg("Time Lapse", "Frame by Frame Movie", R.drawable.timelapse)); items.add(new NameImg("HDR", "High Dinamic Range", R.drawable.hdr)); items.add(new NameImg("IR", "Infra RED Control", R.drawable.ir)); //ft.replace(R.id.dummy, ModeManual.newInstance("Manual")).commit(); break; case 1: items.add(new NameImg("Triggered", "Trigger camera ", R.drawable.triggrered)); items.add(new NameImg("Dark Room", "Long Exposure", R.drawable.darkroom)); items.add(new NameImg("Lightning", "Frame by Frame Movie", R.drawable.lightning)); //ft.replace(R.id.dummy, ModeTriggered.newInstance("Triggered")).commit(); break; case 2: items.add(new NameImg("Bullet", "Simple camera Control", R.drawable.bullet)); items.add(new NameImg("Water drops", "Long Exposure", R.drawable.waterdrops)); //ft.replace(R.id.dummy, ModeBullet.newInstance("Bullet")).commit(); break; case 3: items.add(new NameImg("Manual", "Simple camera Control", R.drawable.pan_manual)); items.add(new NameImg("Programmed", "Long Exposure", R.drawable.pan_auto)); items.add(new NameImg("Star Tracking", "Long Exposure", R.drawable.starstracker)); //ft.replace(R.id.dummy, ModeManualPan.newInstance("Manual Pan")).commit(); break; case 4: items.add(new NameImg("1", "USB1", R.drawable.usb)); items.add(new NameImg("2", "USB2", R.drawable.waterdrops)); //ft.replace(R.id.dummy, ModeUSB1.newInstance("USB 1")).commit(); break; } setListAdapter(new ModesItemAdapter(getActivity(), R.layout.my_list_item, items)); Toast.makeText(getActivity(), "onCreate :" + crtMode, Toast.LENGTH_LONG).show(); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View v = super.onCreateView(inflater, container, savedInstanceState); return v; } @Override public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); getListView().setOnItemClickListener(this); switch (crtMode) { case 0: ft.add(R.id.dummy, ModeManual.newInstance("Manual")).commit(); break; case 1: ft.add(R.id.dummy, ModeTriggered.newInstance("Triggered")).commit(); break; case 2: ft.add(R.id.dummy, ModeBullet.newInstance("Bullet")).commit(); break; case 3: ft.add(R.id.dummy, ModeManualPan.newInstance("Manual Pan")).commit(); break; case 4: ft.add(R.id.dummy, ModeUSB1.newInstance("USB 1")).commit(); break; } } @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Toast.makeText(getActivity(), "onItemClick :" + parent.getItemAtPosition(0).toString(), Toast.LENGTH_LONG).show(); //ft = getFragmentManager().beginTransaction(); //ft.replace(R.id.dummy, ModeManual.newInstance("selected item :" + position + " ID :" + id),"aaa").commit(); } } 1. I need help to figure out how to load at first rut the fragment associalted with the fist tab lv item ft.replace(R.id.dummy, ModeManual.newInstance("Manual")).commit(); How to find out the existing fragment sot when i click a lv item i can replace the correct fragmet? TreKing, i will try to make my questions clear, but i am not dumping code for debbuging i add it in ordre to make the question clear. If too less/much code is posted jut let me know.
