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

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

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.
Any help would be greatly appreciated!

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();
}

I'm trying to use a navigation drawer in my Main activity.
when i run it in API 23 Emulator , everything looks fine.
But when I run it in API 16 Emulator, my action bar goes away!
Here is my manifest file :

</intent-filter>
</activity>
Here is my styles.xml

When I run this code in emulator API 21, everything looks fine.
But when I run it in API 16, i get this error:
"This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_SUPPORT_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead."
I guess it's telling me not to use actionbar, but how can i actually display my navigation drawer if i set windowActionBar to false?
i've tried this topic but it didn't work

Implementing toolbar invoking null object reference

I am having problems implementing the actionbar (which I think is now replaced by toolbar). What I want is a small drop down menu with the 3 dots where I can have a few options such as settings and credits. I have tried to set it up so that the menu appears on the homelistview.java page. I feel like I have been going in circles trying different solutions and getting a new error each time and it always points back to the same location mentioned below.
setSupportActionBar(toolbar);
I had originally thought it was because I didn't include setContentView(R.layout.activity_main); but it was not happy including 2 content views. Any help would be appreciated.
Here is my code.

Your Toolbar toolbar is declared/ initialized in the onCreate only, hence the scope is gone out of that method...
define the object as an activity variable and initialize it in the onCreate
public class HomeActivityListview extends AppCompatActivity {
ListView lv;
Context context;
ArrayList dogName;
ArrayList dogID;
public static int [] dogImages={R.drawable.dogpic};
public static String [] dogNames={};
private Toolbar toolbar; //define it here
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home_activity_listview);
toolbar = (Toolbar) findViewById(R.id.toolbar); //but init here
setSupportActionBar(toolbar);
context=this;
lv=(ListView) findViewById(R.id.listView);
lv.setAdapter(new CustomAdapter(this, dogImages));
}

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 -->

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.

Android: WebView app crashes after 3 seconds of showing Splash screen

so I've decided to make an android application for my website (not many people read it, however I think it'll look good on my Ucas!
My problem is that after the splash screen is displayed on my phone the app crashes, I'm quite new to android app development so I'm unsure about what I'm doing wrong.
I've uploaded my sourcecode on to Github so that you can have a better look at it!
Heres some of my code:

Thank you for any help in advance!

Instead of calling from thread use Handler
protected void onCreate(Bundle savedInstanceState) {
//your stuff.....
new android.os.Handler().postDelayed(new Runnable() {
#Override
public void run() {
if (!isFinishing()) {//just to make sure user didn,t press back button
Intent mainIntent = new Intent(Splashscreen.this, MainActivity.class);
startActivity(mainIntent);
finish();
}
}
}, 3000);//waiting time
}

You can't call startActivity(intent) form inside the thread you've created. Firstly because startActivity(...) is a Context method and secondly, you need to execute this statement on the UI thread.
Try this:
#Override
protected void onCreate(Bundle savedInstanceState) {
...
final Context activity = this;
Thread timerThread = new Thread(new Runnable(
public void run(){
try{
sleep(3000);
}catch(InterruptedException e){
e.printStackTrace();
}finally{
activity.runOnUiThread(new Runnable() {
public void run(){
Intent intent = new Intent(SplashScreen.this,MainActivity.class);
activity.startActivity(intent);
}
});
}
}
));
timerThread.start();

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
public class SearchableActivity extends FragmentActivity implements LoaderCallbacks<Cursor> {

mLVCountries.setAdapter(mCursorAdapter);
// 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);
