How to display ActionBar in the entire App Android

Hello i'm making an application for Android and I added an ActionBarDrawerToggle to the app. When i select an item, the ActionBarDrawerToggle disappear.
What I want to do :
Create the ActionBarDrawerToggle in MainWindow.java [Done]
Create Profil.java and Planning.java and extend MainWindow into Profil and Planning to display the ActionBarDrawerToggle. [Problem]
I'm using :
UPDATE
Mainactivity :
public class MainWindow extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setTheme(R.style.AppTheme_NoActionBar);
setContentView(R.layout.activity_mainwindow);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.mainwindow, 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.nav_profil) {
return true;
}
return super.onOptionsItemSelected(item);
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_profil) {
Intent intent = new Intent(this, Profil.class);
startActivity(intent);
} else if (id == R.id.nav_planning) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
the Profil :
public class Profil extends MainWindow {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.content_profil);
System.out.println("Profil");
}
}
AndroidManifest.xml :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.main">
<!-- To auto-complete the email text field in the login form with the user's emails -->
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_PROFILE" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"

android:supportsRtl="true"
android:theme="#style/AppTheme">

android:name=".MainWindow"
android:label="#string/title_activity_mainwindow"></activity>
<activity
android:name=".Connection"></activity>
<activity
android:name=".Profil"></activity>
</application>
</manifest>

if you are using a material support lib you will have to add the action bar manually in the XML file
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="#dimen/appbar_padding_top"
android:theme="#style/AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/PopupOverlay"/>
</android.support.design.widget.AppBarLayout>
and in the java Activity file in onCreate() method add the following lines
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
Hope this works for you

Be sure #style/AppTheme theme not NoActionBar.

How to link local HTML pages with strings in a navigation drawer?

I have a simple app with a webview to load local HTML pages, I put all my files inside assets, now in my navigation drawer I want to have some text/links that open these pages, I tried to follow some tuts on the web but somehow I can't make it happen.

As I understand you want to load yours html file from assets into WebView by clicking items in drawerMenu? If it's so you you need to add this lines to onClickListener of yours listView in drawer:
mDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(MainActivity.this, "Time for an upgrade!", Toast.LENGTH_SHORT).show();
//load file to webView
mWebView.loadUrl("REPLACE_IT_WITH_PATH_TO_FILE");
//close drawer
mDrawerLayout.closeDrawers();
}

Android SearchView Widget With List Item as a Result

anyone can give me a solution on how to use searchView widget(not in action bar) to show a list of result base on what the user type in searchView.
i am very new in developing android application and it happen that i want to try to create a simple application that can retrieve a data from the database.
i try to search from the internet and i found 'searchView' which i am able to search a data. i copy the code from the internet and modify some part. i read the code, i actually understand some code but not all, now from the MainActivity, i see that the 'onSearchRequested();' is called and then an intent is start with a searchView in action bar.
i try to modify the code with putting a searchView widget at the layout, i want to use this instead of 'onSearchRequested();' but im stock, dont know how show the 'ListView' as the result.
this what the run looks like:
a searchview in actionbar
and i want to change it like:
a searchView with result of list item but not in action bar
the code::
'MainActivity.java' // The original
public class MainActivity extends FragmentActivity{
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn = (Button) findViewById(R.id.btn_search);
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
onSearchRequested(); // This will start eveything on button click
}
});
}
}
'MainActivity.java' // I already Modify
public class MainActivity extends FragmentActivity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn = (Button) findViewById(R.id.btn_search);
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
onSearchRequested();
}
});
SearchView searchView = (SearchView)findViewById(R.id.searchView1);
//This is just some code trying to customize the SearchView
searchView.setQueryHint("Type Word...");
int searchPlateId = searchView.getContext().getResources().getIdentifier("android:id/search_plate", null, null);
View searchPlate = searchView.findViewById(searchPlateId);
if (searchPlate!=null) {
searchPlate.setBackgroundColor(Color.WHITE);
int searchTextId = searchPlate.getContext().getResources().getIdentifier("android:id/search_src_text", null, null);
TextView searchText = (TextView) searchPlate.findViewById(searchTextId);
if (searchText!=null) {
searchText.setTextColor(Color.DKGRAY);
searchText.setHintTextColor(Color.LTGRAY);
}
}
// and im stock here, dont now what next to do
}
}
SearchableActivity.java //Nothings modify here

// Getting the intent that invoked this activity

Again, Please im just a newbie, if there's something wrong on my question im really sorry, i love programming and im just trying to learn. anyway, thank you very much!!! any help will be appreciated!

Just refer this link ..
http://wptrafficanalyzer.in/blog/customizing-autocompletetextview-to-display-images-and-text-in-the-suggestion-list-using-simpleadapter-in-android/
It's not a big deal. If You know the CustomListView then it's easy for you.

Did not understand the whole question, but maybe you want to forget the onSearchRequested(); and change it with your customize searchView. try this,
you dont need to change anything on your code except in MainActivity. if you don't want onSearchRequested(); for some reason... here..
If you have a custom searchView in your actionbar and use it instead of searchView in your layout you may use this code:
public class MainActivity extends FragmentActivity{
static SearchView searchView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
//Your design here
MenuItem menuItem = menu.findItem(R.id.search);
SearchView searchView = (SearchView) menuItem.getActionView();
searchView.setIconifiedByDefault(false);
searchView.setQueryHint("Type something...");
int searchPlateId = searchView.getContext().getResources().getIdentifier("android:id/search_plate", null, null);
View searchPlate = searchView.findViewById(searchPlateId);
if (searchPlate!=null) {
searchPlate.setBackgroundColor(Color.DKGRAY);
int searchTextId = searchPlate.getContext().getResources().getIdentifier("android:id/search_src_text", null, null);
TextView searchText = (TextView) searchPlate.findViewById(searchTextId);
if (searchText!=null) {
searchText.setTextColor(Color.WHITE);
searchText.setHintTextColor(Color.WHITE);
}
}
//Maybe this is what you want
// Associate searchable configuration with the SearchView
SearchManager searchManager =
(SearchManager) getSystemService(Context.SEARCH_SERVICE);
searchView = (SearchView) menu.findItem(R.id.search).getActionView();
searchView.setSearchableInfo(
searchManager.getSearchableInfo(getComponentName()));
return true;
}
}
and in you res/menu/main.xml add this
<item android:id="#+id/search"
android:title="#string/search_title"
android:icon="#drawable/ic_search"
android:showAsAction="collapseActionView|ifRoom"
android:actionViewClass="android.widget.SearchView" />
and try to execute your project
or if you really want to use your custom searchView in your layout then this:
public class MainActivity extends FragmentActivity{
static SearchView searchView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
searchView = (SearchView)findViewById(R.id.searchView1);
searchView.setQueryHint("Type Word...");
int searchPlateId = searchView.getContext().getResources().getIdentifier("android:id/search_plate", null, null);
View searchPlate = searchView.findViewById(searchPlateId);
if (searchPlate!=null) {
searchPlate.setBackgroundColor(Color.WHITE);
int searchTextId = searchPlate.getContext().getResources().getIdentifier("android:id/search_src_text", null, null);
TextView searchText = (TextView) searchPlate.findViewById(searchTextId);
if (searchText!=null) {
searchText.setTextColor(Color.DKGRAY);
searchText.setHintTextColor(Color.LTGRAY);
//This is what you want?
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
searchView.getRootView();//Notice that i change this
searchView.setSearchableInfo(
searchManager.getSearchableInfo(getComponentName()));
}
}
}

android searchview getSearchableInfo throws nullpointer exception

I was trying to implement sample search interface in MainActivity with searchview widget. But it keeps throwing null pointer exception at getSearchableInfo in the onCreateOptionsMenu method of MainActivity.
I already have tried the following things, but nothing has helped. Its just a sample code and its giving me a hard time.:
Using android.support.v7.widget.SearchView or using android.widget.SearchView in menu xml item and the onCreateOptionsMenu of MainActivity.
Using MenuItemCompat or using menu in onCreateOptionsMenu.
Using just getComponentName() or using new ComponentName(this, SearchActivity.class).
Using full path or using relative path for SearchActivity in AndroidManifest.
Adding following line in proguard-android.txt : -keep class android.support.v7.widget.SearchView { *; }
Here is the stacktrace:

Please help me resolve this issue.

How to get results from search result activity?

I have an Activity (MainActivity) with a search button in the action bar. It searches by some input string and shows the results in a ListView in another Activity (SearchResultsActivity). The user might click in any result to select it.
I want to return the value selected by the user to the main activity, but it's not working. I looked in the documentation but I didn't find anything related.
I tried to use setResult(Intent) in the results activity but the onActivityResult() from the main activity never gets called.
What am I doing wrong? How can I do it?

MainActivity:
public class MainActivity extends FragmentActivity {
// ...
#Override
public boolean onCreateOptionsMenu(Menu menu) {
final MenuInflater menuInflater = getMenuInflater();
menuInflater.inflate(R.menu.activity_main_menu, menu);
// Associate searchable configuration with the SearchView
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
return true;
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// never gets called!
super.onActivityResult(requestCode, resultCode, data);
}
// ...
}
SearchResultsActivity:
public class SearchResultsActivity extends Activity {
private ListView listResults;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.search_results);
// get the action bar
ActionBar actionBar = getActionBar();
// Enabling Back navigation on Action Bar icon
actionBar.setDisplayHomeAsUpEnabled(true);
listResults = (ListView) findViewById(R.id.listResults);
handleIntent(getIntent());
}
#Override
protected void onNewIntent(Intent intent) {
setIntent(intent);
handleIntent(intent);
}
/**
* Handling intent data
*/
private void handleIntent(Intent intent) {
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
final Serializable[] results = find(query);
listResults.setAdapter(new ArrayAdapter<BusLine>(this, R.layout.list_view, busLines));
listResults.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Serializable selectedResult = (Serializable) parent.getItemAtPosition(position);
setResult(RESULT_OK, new Intent().putExtra("result", selectedResult));
finish();
}
});
}
}
}

I can understand why you might think that you would use setResult and onActivityResult to handle clicks in your search results activity, but that is not how it works. Only when you launch an activity with startActivityForResult do these functions apply -- not when displaying search results.
The solution is to call startActivity on your MainActivity in the normal fashion, that is, not using activity results. Something like this:
listResults.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Serializable selectedResult = (Serializable) parent.getItemAtPosition(position);
Intent intent = new Intent();
intent.putExtra("result", selectedResult);
intent.setClass(SearchResultsActivity.this, MainActivity.class);
startActivity(intent);
finish();
}
});
Now you will also need to capture this search result in your MainActivity, although you need to make sure you handle the normal case as well as the search results case:
#Override
protected void onCreate(Bundle savedInstanceState) {
Intent intent = getIntent();
if (intent.hasExtra("result")) {
// Launched from search results
Serializable selectedResult = (Serializable) intent.getSerializableExtra("result");
...
}
...
}
