Navigation drawer implementation with activities using inheritance

In my app I have to use navigation drawer with all activities. So I have created a base activity called DrawerActivity. I wrote the code for navigation drawer in DrawerActivity and then extended the UserDashBoardActivity from DrawerActivity.
The problem is that DrawerActivity properties aren't executed in UserDashBoardActivity. I can't interact with DrawerActivity in UserDashBoardActivity. Here that drawer menu is in ActionBar in all the activities.
This is my DrawerActivity
public class DrawerActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.drawer_list_view);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
mDrawerItems = getResources().getStringArray(R.array.navigation_drawer_items_array);
//mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
mDrawerList.setAdapter(new ArrayAdapter<String>(
this, R.layout.drawer_list_items, mDrawerItems));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(this,
mDrawerLayout, R.drawable.ic_menu,
R.string.drawer_open, R.string.drawer_close) {
public void onDrawerOpened(View view) {
invalidateOptionsMenu();
}
public void onDrawerClosed(View view) {
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
for (int index = 0; index < menu.size(); index++) {
MenuItem menuItem = menu.getItem(index);
if (menuItem != null) {
// hide the menu items if the drawer is open
menuItem.setVisible(!drawerOpen);
}
}
return super.onPrepareOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
private class DrawerItemClickListener implements ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
switch (position) {
case 0: {
Intent intent = new Intent(DrawerActivity.this, UserDashBoardActivity.class);
startActivity(intent);
break;
}
case 1: {
Intent intent = new Intent(DrawerActivity.this, AdmissionActivity.class);
startActivity(intent);
break;
}
default:
break;
}
mDrawerLayout.closeDrawer(mDrawerList);
}
}
This is my UseDashBoardActivity
public class UserDashBoardActivity extends DrawerActivity {
private Context context;

}
#Override

}
#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_user_dash_boad, menu);
return true;
}
// delete the selected event from event list added here
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_notify:
return true;
case R.id.action_favourite:
return true;
case R.id.action_navigation:
}
return super.onOptionsItemSelected(item);
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getSupportActionBar().setCustomView(R.layout.action_bar_layout);
setContentView(R.layout.user_dash_board);
context = getApplicationContext();
searchBtn = (ImageButton) findViewById(R.id.search_btn);
favBtn = (ImageButton) findViewById(R.id.fav_btn);
profileBtn = (ImageButton) findViewById(R.id.profile_btn);
reminderBtn = (ImageButton) findViewById(R.id.reminder_btn);
notificationBtn = (ImageButton) findViewById(R.id.notification_btn);
logoutBtn = (ImageButton) findViewById((R.id.logout_btn));
final EditText Search = (EditText)findViewById(R.id.emailAddress);
mDrawerList = (ListView)findViewById(R.id.drawer_layout);
searchBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Intent regAct = new Intent(getApplicationContext(), SearchActivity.class);
// Clears History of Activity
regAct.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(regAct);
}
});
favBtn.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View arg0){
Intent tabAct = new Intent(getApplicationContext(),TabHostActivity.class);
tabAct.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(tabAct);
}
});
profileBtn.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View arg0) {
Intent tabAct = new Intent(getApplicationContext(),AboutCollegeActivity.class);
tabAct.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(tabAct);
}
});
}
}

The UserDashboard activity is executed as it is but I need the property of DrawerActivity to be executed along with this activity. How to do it?

Let the parent Activity add the required ViewGroup as child of the FrameLayout. To achieve this, use the following method for DrawerActivity:
protected void addToContentView(int layoutResID)
{
// as part of onCreate() we had already
// setContentView(R.layout.activity_drawer);
if (layoutResID >= 0)
{
Toast.makeText(this, "activity content found", Toast.LENGTH_LONG).show();
FrameLayout fl = (FrameLayout)findViewById(R.id.activity_frame);
View.inflate(this, layoutResID, fl);
}
else
{
Toast.makeText(this, "activity content missing", Toast.LENGTH_LONG).show();
}
}
Then, in the onCreate() method of the child Activity:
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
// call this instead of setContentView()
addToContentView(R.layout.activity_user_dashboard);
// put here your code as before...
}

Drawer's layout:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
/>
<!--you need to add everything to this frameLayout then only you will be able to access Navigation DrawerLayout-->
<FrameLayout
android:id="#+id/fragment"
android:layout_width="match_parent"
android:layout_height="match_parent"></FrameLayout>
</LinearLayout>
<ListView
android:id="#+id/navigation_list"
android:layout_width="320dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:fitsSystemWindows="true"
android:background="#color/white"
/>
</android.support.v4.widget.DrawerLayout>
The Activity with Drawer:(Only important code is shown)
public abstract class BaseDrawerLayoutActivity extends AppCompatActivity implements OnItemClickListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.base_drawer_layout_activity);
//rest of the things
//NOTE: loadNavMenu is abstract so that you can implement it in other activities as per you need, otherwise remove this and load it here itself
loadNavMenu();
}
protected abstract void loadNavMenu();
// call this method whenever you enter new activity and load the fragment here.
public void showFragment(Fragment object, String title) {
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.fragment, object);
transaction.commit();
}}
Those activities which need the drawer menu can inherit above class. Not inflate all the layout's inside FrameLayout only.
public class MainActivity extends BaseDrawerLayoutActivity {
public static final String TAG = OLMSActivity.class.getSimpleName();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//the method below will call the BaseDrawerLayoutActivity method and change the fragment for you to see.
showFragment(new MyProfileFragment(), "My Profile");
}
#Override
protected void loadNavMenu() {
NavItems.clear();
//load your menu items
}
private void loadNavFavourites(){
//todo
}}
MyProfileFragment is just a class with fragment and this one call inflate a layout in its OnCreateView method.

getViewByID imagebutton is returning null

I have an imageButton on my xml:
<ImageButton
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_marginTop="10dp"
android:id="#+id/star"
android:background="#drawable/star"
android:layout_below="#+id/releaseDate"
android:layout_alignLeft="#+id/releaseDate"
android:layout_alignStart="#+id/releaseDate" />
I want to add the action of the button, but the problem is that the imageButton I created is returning null when fetching the imagebutton on xml with findViewById:
public class DetailActivity extends AppCompatActivity {
ImageButton ib;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_detail);
if(savedInstanceState == null){
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new DetailActivityFragment())
.commit();
ib = (ImageButton)findViewById(R.id.star);
if(ib != null) {
ib.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.v(null, "Image Clicked!");
}
});
}
}
}

Accessing Views inside fragment

I'm having troubles accessing the Views that within my Fragment. In the example below, I can't access the 2nd button that is within the Fragment (e.g., findViewById appears to return NULL and the app crashes when I try b2.setText("test") ), but when I directly add it in the activity_main.xml, it does work.
Here is the code:
MainActivity.java
public class MainActivity extends Activity
{
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final Button fragmentButton = (Button)findViewById(R.id.iMainButton);
FragmentManager fm = getFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.add(R.id.iMainInnerLLContainer, new TestFragment());
ft.commit();
final Button b2 = (Button)findViewById(R.id.iTestFragmentInnerButton);
if(b2 == null) { Log.d("MainActivity.java:", "b2 is null"); }
else { Log.d("MainActivity.java:", "b2 is NOT null"); }
fragmentButton.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
// do stuff here
}
});
}
}
activity_main.xml
<LinearLayout 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:id="#+id/iMainRootLinearLayoutContainer"
android:orientation="vertical"
>
<Button
android:id="#+id/iMainButton"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:text="Add fragment..."
/>
<LinearLayout
android:id="#+id/iMainInnerLLContainer"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:orientation="vertical"
>
<!-- Fragment goes here, can reference button if it is added here manually -->
</LinearLayout>
</LinearLayout>
TestFragment.java
public class TestFragment extends Fragment
{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
return inflater.inflate(R.layout.ltestfragment, container, false);
}
}
ltestfragment.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:id="#+id/iTestFragmentOuterLinearLayout"
>
<Button
android:id="#+id/iTestFragmentInnerButton"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:text="This is my test fragment button."
/>
</LinearLayout>
I think I'm missing something very basic here and I would appreciate some insight on what that might be.
Thank you in advance!

I think you need to set up a textchangelistener in your fragment.
public class FragmentA extends Fragment {
TextChangeListener listener;
public interface TextChangeListener {
public void onTextChange(CharSequence newText);
}
public void setTextChangeListener(TextChangeListener listener) {
this.listener = listener;
}
Then, in your activity, set up the listener :
public class ActivityAB extends FragmentActivity {
FragmentA fragmentA;
FragmentB fragmentB;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ab);
FragmentManager manager = getSupportFragmentManager();
fragmentA = (FragmentA) manager.findFragmentById(R.id.fragmentA);
fragmentB = (FragmentB) manager.findFragmentById(R.id.fragmentB);
fragmentA.setTextChangeListener(new TextChangeListener() {
#Override
public void onTextChange(CharSequence newText) {
fragmentB.updateTextValue(newText);
}
});
}
}

Implement an interface to listen to the events of a fragment from its activity.
Code in Fragment:-
public class TestFragment extends Fragment
{
public interface OnClickListener
{
public void onButtonClicked(<data type><data>);
}
b2.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
listener.onButtonClicked(<<pass some values here>>);
}
});
}
Code in Main:-
MainActivity extends FragmentActivity implements TestFragment.OnClickListener,
{
#Override
public void onButtonClicked(<<receive the pased data here>>) {
//do some stuff here with the received data after the button is clicked
}
}

Adding a button in an activity within fragments with Actionbarsherlock inside the fragment

So I want to have 3 buttons that always appear throughout fragments. I've got an activity with 3 buttons and a fragment layout that contains a fragment with actionbarsherlock inside. The problem is, the buttons in the activity are not clickable and nothing can be executed in the OnClickListener; but the buttons run just fine if I replace the fragment containing actionbarsherlock with a regular fragment without actionbarsherlock inside. I wonder what's wrong.
Here is my code.
activity_main.xml:
<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:paddingBottom="2dp"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<FrameLayout
android:id="#+id/fragment_content"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#+id/button1" />
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/fragment_content"
android:layout_alignParentBottom="true"
android:layout_marginBottom="10dp"
android:text="mission" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#+id/button1"
android:layout_alignBottom="#+id/button1"
android:layout_centerHorizontal="true"
android:text="feed" />
<Button
android:id="#+id/button3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#+id/button2"
android:layout_alignBottom="#+id/button2"
android:layout_alignRight="#+id/fragment_content"
android:text="Profile" />
</RelativeLayout>
MyActivity.java:
public class MyActivity extends SherlockFragmentActivity {
/**
* Called when the activity is first created.
*/
Fragment frg;
ActionBarFragment b;
Button btnmission;
Button btnfeed;
Button btnprofile;
boolean small;
static int previousItem;
int tabname;
private Fragment mVisible = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
previousItem=1;
btnmission = (Button) findViewById(R.id.button1);
btnfeed = (Button) findViewById(R.id.button2);
btnprofile = (Button) findViewById(R.id.button3);
btnmission.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Log.i("clicked", "button");
if(previousItem!=1){
Intent intent=new Intent(getBaseContext(),MyActivity.class);
startActivity(intent);
}
previousItem=1;
}
});
btnfeed.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if(previousItem!=2){
Intent intent=new Intent(getBaseContext(),MissionFragment.class);
intent.putExtra("class", "Feed");
startActivity(intent);
}
previousItem=2;
}
});
btnprofile.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
}
});
private void setupFragments() {
final FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
frg = (ActionBarFragment) getSupportFragmentManager().findFragmentById(R.id.fragment_content);
if (frg == null) {
frg = new ActionBarFragment();
ft.add(R.id.fragment_content, frg);
}
ft.hide(frg);
ft.commit();
}
private void showFragment(Fragment fragmentIn) {
if (fragmentIn == null) return;
final FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.setCustomAnimations(android.R.anim.fade_in, android.R.anim.fade_out);
if (mVisible != null) ft.hide(mVisible);
ft.show(fragmentIn).commit();
mVisible = fragmentIn;
}
It adds a fragment to the activity and actionbar inside the fragment.
ActionBarFragment.java:
public class ActionBarFragment extends SherlockFragment {
int tabname;
#Override
public void onStart()
{
// TODO Auto-generated method stub
super.onStart();
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.empty_view, container, false);
// Getting an instance of action bar
ActionBar actionBar = this.getSherlockActivity().getSupportActionBar();
// Enabling Tab Navigation mode for this action bar
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Enabling Title
actionBar.setDisplayShowTitleEnabled(true);
// Creating Android Tab
Tab tab1 = actionBar.newTab()
.setText("Nova Missoes")
.setTabListener(new CustomTabListener<ListMission>(this.getSherlockActivity(), "mission list", ListMission.class));
// Adding Android Tab to action bar
actionBar.addTab(tab1);
// Creating Apple Tab
Tab tab2 = actionBar.newTab()
.setText("Missoes Concluidas")
.setTabListener(new CustomTabListener<MissionAccomplished>(this.getSherlockActivity(), "mission accomplished", MissionAccomplished.class));
// Adding Apple Tab to action bar
actionBar.addTab(tab2);
Intent in=getSherlockActivity().getIntent();
tabname=in.getIntExtra("tabname", 0);
Log.i("intent", Integer.toString(tabname));
if(tabname==2){
actionBar.selectTab(tab2);
}
// Orientation Change Occurred
if(savedInstanceState!=null){
int currentTabIndex = savedInstanceState.getInt("tab_index");
actionBar.setSelectedNavigationItem(currentTabIndex);
}
return view;
}
#Override
public void onSaveInstanceState(Bundle outState) {
int currentTabIndex = getSherlockActivity().getSupportActionBar().getSelectedNavigationIndex();
outState.putInt("tab_index", currentTabIndex);
super.onSaveInstanceState(outState);
}
}
No problem with displaying the buttons and the tabs, it's just that the OnClickListener is not called when the program runs.

Click event for flipview or swipe view

I'm trying to implement the Click event for fragments that display images or buttons.
I am able to implement the flip view to get another fragment but I am unable get the click event working on such fragments.
I have tried with android:onClick, even setting clickable to true. I even tried with onClickListener and onTouch but it's not firing for me.
This is the code I have tried.
public class MainActivity extends Activity {
private FlipViewGroup contentView;
public int currentimageindex=0;
private GestureDetector mDetector;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
// hde staitbar otef Andoroid
// could also be usdne lar
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setTitle(R.string.activity_title);
contentView = new FlipViewGroup(this);
contentView.addFlipView(View.inflate(this, R.layout.second_page, null));
contentView.addFlipView(View.inflate(this, R.layout.first_page, null));
setContentView(contentView);
// setContentView(R.layout.second_page);
contentView.startFlipping(); //make the first_page view flipping
ImageView imgFavorite = (ImageView) findViewById(R.id.imageView1);
imgFavorite.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(MainActivity.this,
"The favorite list would appear on clicking this icon",
Toast.LENGTH_LONG).show();
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
}
#Override
protected void onResume() {
super.onResume();
contentView.onResume();
}
#Override
protected void onPause() {
super.onPause();
contentView.onPause();
}
public void onclick(View v){
ImageView imgFavorite = (ImageView) findViewById(R.id.imageView1);
imgFavorite.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(MainActivity.this,
"The favorite list would appear on clicking this icon",
Toast.LENGTH_LONG).show();
}
});
}
}

Is there some reason a fragment within a flip view doesn't respond to click or touch events, or is there something I'm doing wrong in my code?

As far as i understand, FlipViewGroup is your custom view group implementation.
If that is the case you need onInterceptTouchEvent() see the sample code here.
