J'ai du mal à faire enregistrer et démarrer les éléments du tiroir de navigation et l'intention d'une nouvelle activité. Le tiroir s'ouvre bien et s'affiche correctement mais rien ne se passe lorsque je clique sur les éléments de la liste. Voici mon code qui est extrait des didacticiels google.
mTitle = mDrawerTitle = getTitle();
mTitles = getResources().getStringArray(R.array.menu_items);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
// set a custom shadow that overlays the main content when the drawer opens
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
// set up the drawer's list view with items and click listener
mDrawerList.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_list_item, mTitles));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
// enable ActionBar app icon to behave as action to toggle nav drawer
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
// ActionBarDrawerToggle ties together the the proper interactions
// between the sliding drawer and the action bar app icon
mDrawerToggle = new ActionBarDrawerToggle(
this, /* Host Activity */
mDrawerLayout, /* DrawerLayout object */
R.drawable.ic_drawer, /* nav drawer image to replace 'Up' caret */
R.string.drawer_open, /* "open drawer" description for accessibility */
R.string.drawer_close /* "close drawer" description for accessibility */
) {
public void onDrawerClosed(View view) {
getActionBar().setTitle(mTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle(mDrawerTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
// if (savedInstanceState == null) {
selectItem(0);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
return super.onCreateOptionsMenu(menu);
}
/* Called whenever we call invalidateOptionsMenu() */
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
// If the nav drawer is open, hide action items related to the content view
boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
// menu.findItem(R.id.action_websearch).setVisible(!drawerOpen);
return super.onPrepareOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// The action bar home/up action should open or close the drawer.
// ActionBarDrawerToggle will take care of this.
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
/* The click listner for ListView in the navigation drawer */
private class DrawerItemClickListener implements ListView.OnItemClickListener {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
selectItem(position);
}
}
private void selectItem(int position) {
switch (position) {
case 1:
new DataTask(MainActivity.this).execute();
MainActivity.this.finish();//Set this Activity to Finish so no loop back
Intent intent=new Intent(MainActivity.this,SplashScreen.class);
startActivity(intent);
break;
case 2:
// ft.replace(R.id.content_frame, new SecondFragment());
// setTitle("Second");
break;
case 3:
// ft.replace(R.id.content_frame, new ThirdFragment());
// setTitle("Third");
break;
default:
break;
}
// update selected item and title, then close the drawer
mDrawerList.setItemChecked(position, true);
//setTitle(mTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
}
@Override
public void setTitle(CharSequence title) {
mTitle = title;
getActionBar().setTitle(mTitle);
}
/**
* When using the ActionBarDrawerToggle, you must call it during
* onPostCreate() and onConfigurationChanged()...
*/
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
mDrawerToggle.syncState();
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Pass any configuration change to the drawer toggls
mDrawerToggle.onConfigurationChanged(newConfig);
}
/**
* Fragment that appears in the "content_frame", shows a planet
*/
public static class PlanetFragment extends Fragment {
public static final String ARG_PLANET_NUMBER = "planet_number";
public PlanetFragment() {
// Empty constructor required for fragment subclasses
}
// @Override
/* public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_planet, container, false);
int i = getArguments().getInt(ARG_PLANET_NUMBER);
String planet = getResources().getStringArray(R.array.planets_array)[i];
int imageId = getResources().getIdentifier(planet.toLowerCase(Locale.getDefault()),
"drawable", getActivity().getPackageName());
((ImageView) rootView.findViewById(R.id.image)).setImageResource(imageId);
getActivity().setTitle(planet);
return rootView; */

Si vous pouvez apporter une aide, ce serait formidable, car je m'arrache vraiment les cheveux. Je vous remercie.
Le problème est la commande z. Lorsque vous développez la liste dans onDrawerOpened
mettez:
mDrawerList.bringToFront();
mDrawerLayout.requestLayout();
Dans cet article, expliquez le problème et comment le résoudre: http://vardhan-justlikethat.blogspot.com.es/2014/05/Android-custom-navigation-drawer-not.html
Correction d'un problème similaire en ajoutant drawerView.bringToFront();
à
@Override
public void onDrawerOpened(View drawerView) {
}
Si vous avez une liste dans le tiroir de navigation, écrivez simplement le code et rendez la vue de liste cliquable:
list.bringToFront();
drawerLayout.requestLayout();
Vous devez vérifier si vous avez Android:animateLayoutChanges="true"
attribut sur le parent ListView (dans la ressource de disposition). La suppression de cet attribut a fonctionné pour moi.
Il semble que votre DrawerItemClickListener.class
Ne fonctionne pas car la seule fois que la méthode selectItem()
est appelée est à la fin de vos activités onCreate()
at selectItem(0);
Au lieu d'appeler
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
vous pouvez utiliser this
comme paramètre et vous laisser Activity
implémenter le ListView.OnItemClickListener
lui-même.
public class MyActivity extends Activity implements ListView.OnItemClickListener {
public void onCreate(Bundle savedInstanceState) {
[...]
mDrawerList = (ListView) findViewById(R.id.left_drawer);
[...]
mDrawerList.setOnItemClickListener(this);
[...]
}
[...]
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
selectItem(position);
}
private void selectItem(int position) {
switch (position) {
case 1:
[...]
startActivity(new Intent(this, SplashScreen.class));
break;
[...]
default:
break;
}
[...]
}
[...]
}
J'ai également eu un problème avec ne pas répondre sur le pilote de navigation de clics. D'une manière ou d'une autre, j'ai trouvé une solution: le problème était dans un fichier XML. Je l'ai utilisé et mon problème a disparu:
<Android.support.v4.widget.DrawerLayout
xmlns:Android="http://schemas.Android.com/apk/res/Android"
Android:id="@+id/drawer_layout"
Android:layout_width="match_parent"
Android:layout_height="match_parent">
<!-- As the main content view, the view below consumes the entire
space available using match_parent in both dimensions. -->
<FrameLayout
Android:id="@+id/content_frame"
Android:layout_width="match_parent"
Android:layout_height="match_parent" />
<!-- Android:layout_gravity="start" tells DrawerLayout to treat
this as a sliding drawer on the left side for left-to-right
languages and on the right side for right-to-left languages.
The drawer is given a fixed width in dp and extends the full height of
the container. A solid background is used for contrast
with the content view. -->
<ListView
Android:id="@+id/left_drawer"
Android:layout_width="240dp"
Android:layout_height="match_parent"
Android:layout_gravity="start"
Android:choiceMode="singleChoice"
Android:divider="@Android:color/transparent"
Android:dividerHeight="0dp"
Android:background="#ffff"/>
espérons que ce sera utile.
