Android fragment & activity? - android

I create a simple app with navigation drawer, this is the code of drawer:
public class NavigationDrawerFragment extends Fragment {
private static final String STATE_SELECTED_POSITION = "selected_navigation_drawer_position";
private static final String PREF_USER_LEARNED_DRAWER = "navigation_drawer_learned";
private NavigationDrawerCallbacks mCallbacks;
private ActionBarDrawerToggle mDrawerToggle;
private DrawerLayout mDrawerLayout;
private ListView mDrawerListView;
private View mFragmentContainerView;
private int mCurrentSelectedPosition = 0;
private boolean mFromSavedInstanceState;
private boolean mUserLearnedDrawer;
public NavigationDrawerFragment() {
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Read in the flag indicating whether or not the user has demonstrated awareness of the
// drawer. See PREF_USER_LEARNED_DRAWER for details.
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(getActivity());
mUserLearnedDrawer = sp.getBoolean(PREF_USER_LEARNED_DRAWER, false);
if (savedInstanceState != null) {
mCurrentSelectedPosition = savedInstanceState.getInt(STATE_SELECTED_POSITION);
mFromSavedInstanceState = true;
}
// Select either the default item (0) or the last selected item.
selectItem(mCurrentSelectedPosition);
}
#Override
public void onActivityCreated (Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
// Indicate that this fragment would like to influence the set of actions in the action bar.
setHasOptionsMenu(true);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
mDrawerListView = (ListView) inflater.inflate(
R.layout.fragment_navigation_drawer, container, false);
mDrawerListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
selectItem(position);
}
});
mDrawerListView.setAdapter(new ArrayAdapter<String>(
getActionBar().getThemedContext(),
android.R.layout.simple_list_item_1,
android.R.id.text1,
new String[]{
getString(R.string.title_section1),
getString(R.string.title_section2),
getString(R.string.title_section3),
getString(R.string.title_section4),
getString(R.string.title_section5),
}));
mDrawerListView.setItemChecked(mCurrentSelectedPosition, true);
return mDrawerListView;
}
public boolean isDrawerOpen() {
return mDrawerLayout != null && mDrawerLayout.isDrawerOpen(mFragmentContainerView);
}
public void setUp(int fragmentId, DrawerLayout drawerLayout) {
mFragmentContainerView = getActivity().findViewById(fragmentId);
mDrawerLayout = drawerLayout;
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
// set up the drawer's list view with items and click listener
ActionBar actionBar = getActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(
getActivity(), /* host Activity */
mDrawerLayout, /* DrawerLayout object */
R.drawable.ic_drawer, /* nav drawer image to replace 'Up' caret */
R.string.navigation_drawer_open, /* "open drawer" description for accessibility */
R.string.navigation_drawer_close /* "close drawer" description for accessibility */
) {
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
if (!isAdded()) {
return;
}
getActivity().supportInvalidateOptionsMenu(); // calls onPrepareOptionsMenu()
}
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
if (!isAdded()) {
return;
}
if (!mUserLearnedDrawer) {
mUserLearnedDrawer = true;
SharedPreferences sp = PreferenceManager
.getDefaultSharedPreferences(getActivity());
sp.edit().putBoolean(PREF_USER_LEARNED_DRAWER, true).commit();
}
getActivity().supportInvalidateOptionsMenu(); // calls onPrepareOptionsMenu()
}
};
if (!mUserLearnedDrawer && !mFromSavedInstanceState) {
mDrawerLayout.openDrawer(mFragmentContainerView);
}
mDrawerLayout.post(new Runnable() {
#Override
public void run() {
mDrawerToggle.syncState();
}
});
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
private void selectItem(int position) {
mCurrentSelectedPosition = position;
if (mDrawerListView != null) {
mDrawerListView.setItemChecked(position, true);
}
if (mDrawerLayout != null) {
mDrawerLayout.closeDrawer(mFragmentContainerView);
}
if (mCallbacks != null) {
mCallbacks.onNavigationDrawerItemSelected(position);
}
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
try {
mCallbacks = (NavigationDrawerCallbacks) activity;
} catch (ClassCastException e) {
throw new ClassCastException("Activity must implement NavigationDrawerCallbacks.");
}
}
#Override
public void onDetach() {
super.onDetach();
mCallbacks = null;
}
#Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putInt(STATE_SELECTED_POSITION, mCurrentSelectedPosition);
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Forward the new configuration the drawer toggle component.
mDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
if (mDrawerLayout != null && isDrawerOpen()) {
inflater.inflate(R.menu.global, menu);
showGlobalContextActionBar();
}
super.onCreateOptionsMenu(menu, inflater);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
if (item.getItemId() == R.id.action_example) {
Toast.makeText(getActivity(), "Example action.", Toast.LENGTH_SHORT).show();
return true;
}
return super.onOptionsItemSelected(item);
}
private void showGlobalContextActionBar() {
ActionBar actionBar = getActionBar();
actionBar.setDisplayShowTitleEnabled(true);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);
actionBar.setTitle(R.string.app_name);
}
private ActionBar getActionBar() {
return ((ActionBarActivity) getActivity()).getSupportActionBar();
}
public static interface NavigationDrawerCallbacks {
/**
* Called when an item in the navigation drawer is selected.
*/
void onNavigationDrawerItemSelected(int position);
}
}
while this is the code for switch:
public void onNavigationDrawerItemSelected(int position) {
FragmentManager fragmentManager = getSupportFragmentManager();
Fragment fragment = null;
switch (position) {
case 0:
fragment = new MetaioFragment();
fragmentManager.beginTransaction()
.replace(R.id.container, fragment)
.commit();
break;
case 1:
/*
fragment = new GalleryFragment();
fragmentManager.beginTransaction()
.replace(R.id.container, fragment)
.commit();
*/
Intent i = new Intent(this,MyActivity.class);
startActivity(i);
break;
with fragment I have no problem while if I try to open an activity I get this error:
java.lang.RuntimeException: Unable to start activity ComponentInfo java.lang.IllegalArgumentException: No view found for id 0x7f080044 for fragment MyFragment{65777f20 #1 id=0x7f080044}
and a lot of other error, where is the mistake?

You are missing setContentView. Your Fragment can not be added without a View hierarchy.
Your issue is possibly similar to this one.

Android Navigation Drawer can't click on one item

I have a really interesting problem with my Navigator menu.
I have no idea why... But I can click on any item from my menu, I don't want to say I click and nothing happened. I really want to say I can't click on any item, all my menu it's like a big image.
I've try to make a new project witch already have Navigation Drawer Activity, of course it works.. but when I've try to copy that code and put on mine.. I have the same problem and vice versa, I've try to put my code into a new project with Navigation Drawer Activity, but again... I can't click on any item.
Here it's one image with my aplication.
Here it's my Main Activity:

Custom navigation drawer list view

Hi i'm new to the android world and i generated a navigation drawer with the default template in android studio.I'm looking for a way to make section in my listview like this :![enter image description here][1]
How i want my listview to be : https://camo.githubusercontent.com/7043b4240e1be50bb68b3f101c1f9815c9be0f11/68747470733a2f2f7261772e6769746875622e636f6d2f6e656f6b7265652f4d6174657269616c4e617669676174696f6e4472617765722f6d61737465722f73637265656e312e6a7067
Here is the code of my fragment,i really don't know how to do this and i want to have the image on the top with the email like the photo with two section:
public class NavigationDrawerFragment extends Fragment {

i have to finish this to next week cause it's a project at school :(
You can customize the navigation drawer with the proper layout you need.
You can inflate any layout with in the drawer and make proper logic to implement.
You need to modify the method
onCreateView();
For a particular layout you can modify as -
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView= inflater.inflate(
R.layout.fragment_navigation_drawer_layout, container, false);
return rootView;
}
Here
fragment_navigation_drawer_layout
is the layout you want to set.

Adding icon in the default navigation drawer in Android Studio

I want to add icon in front of each item of the list view but i dont know how to do this because i dont understand the whole code of the navigation drawer
Create a custom ArrayAdapter and use a custom layout inside it which has an ImageView and a TextView
Try this
The xml file(call it whatever you want):
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="Medium Text"
android:id="#+id/textViewListItem"
android:layout_marginTop="25dp"
android:layout_marginLeft="10dp"
android:layout_gravity="center_horizontal" />
<ImageView
android:layout_width="45dp"
android:layout_height="45dp"
android:layout_marginLeft="15dp"
android:layout_marginTop="-40dp"
android:id="#+id/imageView"
android:src="#drawable/ic_launcher" />
</LinearLayout>
Create a class that will be your adapter, how your list wants to be(have an imageview, have 3 textviews, etc)
public class ListAdapter extends Activity {
private int imageId;
private String itemName;
public ListaAdapter(int imageId, String itemName) {
super();
this.imageId = imageId;
this.itemName = itemName;
}
public int getImageId() {
return imageId;
}
public void setImageId(int imageId) {
this.imageId = imageId;
}
public String getItemName() {
return itemName;
}
public void setItemName(String itemName) {
this.itemName = itemName;
}
}
then in your activity that you would like the drawer to be implemented try
//instanciate components
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mDrawerToggle;
private ListView mDrawerList;
private List<ListAdapter> drawerList = new ArrayList<ListAdapter>();
//in the onCreate method build 3 methods and organize your code
buildDrawer();
populateDrawerList();
buildListDrawer();
private void populateDrawerList() {
drawerList.add(new ListaAdapter(R.drawable.icon_1, "String 1"));
drawerList.add(new ListaAdapter(R.drawable.icon_2, "String 2"));
}
private void buildDrawer() {
mDrawerLayout = (DrawerLayout)findViewById(R.id.your_drawer_layout);
mDrawerToggle = new ActionBarDrawerToggle(YourActivity.this, mDrawerLayout, R.drawable.your_drawer_icon, "Open", "Closed"){
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
getActionBar().setTitle("Drawer Opened");
invalidateOptionsMenu();
}
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
getActionBar().setTitle("Drawer Closed");
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
private void buildListDrawer() {
mDrawerList = (ListView)findViewById(R.id.listViewDrawer);
ArrayAdapter<ListAdapter> adapter = new MyDrawerArrayAdapter();
mDrawerList.setAdapter(adapter);
mDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(MyActivity.this, "You have chosen " + drawerList.get(position).getItemName(), Toast.LENGTH_SHORT).show();
}
});
}
and then your modified Adapter that extends ArrayAdapter:
private class MyDrawerArrayAdapter extends ArrayAdapter<ListAdapter> {
public MyDrawerArrayAdapter() {
super(MyActivity.this, R.layout.drawer_list_item_layout, drawerList);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View drawerView = convertView;
if(drawerView == null){
drawerView = getLayoutInflater().inflate(R.layout.drawer_list_item_layout, parent, false);
}
ListAdapter currentPosition = drawerList.get(position);
ImageView drawerImage = (ImageView)drawerView.findViewById(R.id.your_drawerImage);
drawerImage.setImageResource(currentPosition.getImageId());
TextView drawerText = (TextView)drawerView.findViewById(R.id.your_drawerText);
drawerText.setText(currentPosition.getItemName());
return drawerView;
}
}
Step 01 -
Have your res/drawable folder ready with appropriate icons.
Step 02 -
In your values/string.xml add below
<string-array name="mydrawerList">
<item>item 1</item>
<item>item 2</item>
<item>item 3</item>
</string-array>
<array name="mydrawerList_icons">
<item>#drawable/ic_for_item1</item>
<item>#drawable/ic_for_item2</item>
<item>#drawable/ic_for_item3</item>
</array>
make sure you have icons in the "mydrawerList_icons" ordered as "mydrawerList" order.
Step 03 -
in your NavigationDrawerFragment.java add below lines
private String[] listTitles;
private TypedArray listIcons;
in onCreate()
listTitles = getResources().getStringArray(R.array.mydrawerList);
listIcons = getResources().obtainTypedArray(R.array.mydrawerList_icons);
Step 04 -
instead of this
mDrawerListView.setAdapter(new ArrayAdapter<String>(
getActionBar().getThemedContext(),
android.R.layout.simple_list_item_activated_1,
android.R.id.text1,
new String[]{
getString(R.string.title_section1),
getString(R.string.title_section2),
getString(R.string.title_section3),
getString(R.string.title_section4),
getString(R.string.title_section5),
getString(R.string.title_section6),
}));
type this
mDrawerListView.setAdapter(new ArrayAdapter<String>(
getActionBar().getThemedContext(),
android.R.layout.simple_list_item_activated_1,
android.R.id.text1,
listTitles)
{
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = super.getView(position, convertView, parent);
int resourceId = listIcons.getResourceId(position, 0);
Drawable drawable = getResources().getDrawable(resourceId);
((TextView) v).setCompoundDrawablesWithIntrinsicBounds(drawable, null, null, null);
return v;
}
});
Let me know the output.

my android action bar menu xml is:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainActivity" >
<item android:id="#+id/menu_search2"
android:actionViewClass="android.widget.SearchView"
android:title="Search"
android:icon="#android:drawable/ic_menu_search"
android:showAsAction="ifRoom|collapseActionView"
/>
</menu>
The activity this fragment is loaded into is:

looks like here
searchView.setIconified(false);
"searchView" has not been initialized properly yet, because before you create the field, but didn't assign any view for it:
SearchView searchView;
So in your onCreateView you should find your View by Id first before calling methods of searchView:
searchView = (SearchView) findViewById(R.id.the_view_id_here);
