How to sync with time in custom calendar that I have made.? Like when I open my calendar it should show the current date and month

Main Activity ScreenI have made a custom calendar with textview, So I want the calendar to show current date and month when I open the calendar...
`My calendar should open directly in the current month and show the current date, just like google calendar.
<TextView
android:textColor="#color/Blue"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_weight="1"
android:fontFamily="#font/caviardreams"
android:gravity="top|center"
android:text="1"
android:textSize="11sp"
android:textStyle="bold"
android:maxWidth="1dp"
android:maxHeight="1dp"/>
<TextView
android:textColor="#color/Blue"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_weight="1"
android:fontFamily="#font/caviardreams"
android:gravity="top|center"
android:text="2"
android:textSize="11sp"
android:textStyle="bold"
android:maxWidth="1dp"
android:maxHeight="1dp"/>
<TextView
android:textColor="#color/Blue"

android:gravity="top|center"
android:text="3"
android:textSize="11sp"
android:textStyle="bold"

I expect the current date to be highlighted in the current month.

Context for onOptionsItemSelected in app-wide menu

This app has just two activities. MainActivity was renamed to SpecialsActivity. The other activity is PizzaActivity. Using the BottomNavigationView, I want to navigate between the two activities. So far, the app opens in SpecialsActivity, and the pizza button does open the PizzaActivity. But then it will not switch back to the SpecialsActivity. I think the issue is related to context. Please help.
SpecialsActivity.java
public class SpecialsActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_specials);
Toolbar myToolbar = findViewById(R.id.my_toolbar);
setSupportActionBar(myToolbar);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_specials:
Intent specials_intent = new Intent(this, SpecialsActivity.class);
startActivity(specials_intent);
return true;
case R.id.action_pizza:
Intent pizza_intent = new Intent(getApplicationContext(), PizzaActivity.class);
startActivity(pizza_intent);
return true;
default:
// Do nothing
}
return super.onOptionsItemSelected(item);
}
}
activity_specials.xml
<android.support.design.widget.BottomNavigationView
android:layout_width="0dp"
android:layout_height="49dp"
app:itemBackground="#color/colorPrimaryDark"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"

<activity android:name=".SpecialsActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".PizzaActivity"></activity>
</application>
bottom_menu.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"

<item

android:title="Specials"
app:showAsAction="always"
android:onClick="onOptionsItemSelected" />
<item

android:enabled="true"
android:icon="#drawable/ic_local_pizza_black_24dp"
android:title="Pizza"
app:showAsAction="always"

</menu>

Try changing
Intent pizza_intent = new Intent(getApplicationContext(), PizzaActivity.class);
into this
Intent pizza_intent = new Intent(this, PizzaActivity.class);

Run Time Main Activity not come after Splash Activity and app close

Everything in my code looks good in both the .java and .xml files (according to the software) because I have no errors yet every time I click the app icon in the emulator, it brings up the splash screen then the app exits without showing my main activity. Here's my code so far:
SplashActivity.java
public class SplashActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//hide title bar of activity
getWindow().requestFeature(Window.FEATURE_NO_TITLE);
//Making activity full screen
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_splash);
int t =3000; //time for spash screen 3000 means 3sec
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
startActivity(new Intent(SplashActivity.this, MainActivity.class));
}
},t);
}
}
SplashActivity.xml
<ImageView
android:layout_width="250dp"
android:layout_height="250dp"

super.onProgressChanged(view, newProgress);

return super.onKeyDown(keyCode, event);

Any hints would be greatly appreciated, thank you!

The problem is in onCreate method of MainActivity, you do not provide any UI (xml layout file), as a result, the app cannot find view elements to init, set listeners, etc. I guess you can find an exception in logcat when your app close.
Solution: Provide a layout xml file for MainActivity
public class MainActivity extends AppCompatActivity {
String webAdress ="https://www.google.com/";
WebView webView;
FrameLayout frameLayout;
ProgressBar progressBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); // Add this line
webView = (WebView) findViewById(R.id.webView);
...
}
}

try use
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
finish();

Your code is not so good. If you want to show splashscreen only when app start I recommend using the following code:
AndroidManifest.xml
<activity android:name=".view_layer.activities.SplashScreenActivity"
android:theme="#style/SplashTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
styles.xml
<style name="SplashTheme" parent="#android:style/Theme.NoTitleBar.Fullscreen">
<item name="android:windowBackground">#drawable/splash</item>
</style>
SplashscreenActivity.java
public class SplashscreenActivity extends AppCompatActivity {
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
startActivity(new Intent(this, MainActivity.class));
finish();
}
}

Select Item on Spinner

I want to ask for help.
I already created a list of activities in Android Studio.
Each Activity contains a specific item. Those items are different "Departments" in our University.
Example:
Activity 1 = College of Computer Studies;
Activity 2 = College of Teacher Education;
Activity 3 = College of Engineering.
My Spinner contains the departments.
My problem is, if I choose "College in Computer Science" in Spinner and click the "SEND" button, I want Activity 1 to be shown.
Would you help me with the code to do that?
**Spinner in activity_main.xml
<Spinner
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/spin"
android:entries="#array/punpDepartments"
android:layout_gravity="center_vertical">
</Spinner>
**These are the items in strings.xml
<string-array name="punpDepartments">
<item>College of Computer Studies</item>
<item>College of Business Education</item>
<item>College of Criminal Justice Education</item>
<item>College of Marine Education</item>
<item>College of Nursing</item>
<item>College of Pharmacy</item>
<item>College of Education</item>
**My code in Intent at MainActivity.java
public class MainActivity extends ActionBarActivity {
private static Button button_send;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
OnClickButtonListener();
}
public void OnClickButtonListener(){
button_send = (Button) findViewById(R.id.button);
button_send.setOnClickListener(
new View.OnClickListener(){
#Override
public void onClick(View v){
Intent intent = new Intent("com.example.imelda.mythesis.ListActivity");
startActivity(intent);
}
}
);
}
**Extends in ListActivity.java
public class ListActivity extends ActionBarActivity {
private static Button button_next;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list);
OnClickButtonListener();
}
#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_list, menu);
return true;
}
public void OnClickButtonListener() {
button_next = (Button) findViewById(R.id.button4);
button_next.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent("com.example.imelda.mythesis.SecondList");
startActivity(intent);
}
}
);
}
**I have also added this in AndroidManifest.xml enter code here
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.imelda.mythesis" >
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />

<intent-filter>
<action android:name="com.example.imelda.mythesis.ListActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>

first get your spinner in the main class like this
Spinner spin =(Spinner)findViewById(R.id.spin);
now in your on click method do this
int position =spin.getSelectedItemPosition();
//change the activities with yours
switch (position){
case 0: intent.setClass(Activity1.class,MainActivity.this);
break;
case 1: intent.setClass(Activity2.class,MainActivity.this);
break;
case 2: intent.setClass(Activity3.class,MainActivity.this);
break;
case 3: intent.setClass(Activity4.class,MainActivity.this);
break;
case 4: intent.setClass(Activity5.class,MainActivity.this);
break;
}
startActivity(intent);

icon not displayed on actionbar

I was going through the tutorial by google and couldn't figure out how to place search icon on action bar.
this is the main_activity_actions.xml code :-
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- Search, should appear as action button -->
<item android:id="#+id/action_search"
android:orderInCategory="100"
android:icon="#drawable/ic_action_search"
android:title="#string/action_search"
android:showAsAction="always" />
<!-- Settings, should always be in the overflow -->
<item android:id="#+id/action_settings"
android:title="#string/action_settings"
android:showAsAction="never" />
</menu>
this is the MainActivity.java :-
public class MainActivity extends ActionBarActivity
{
public final static String EXTRA_MESSAGE = "com.example.myfirstapp.MESSAGE";
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_display_message);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
if (savedInstanceState == null)
{
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment()).commit();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_activity_actions, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle presses on the action bar items
switch (item.getItemId()) {
case R.id.action_search:
openSearch();

I have already seen few answers and posted an the stack overflow and tried them and it still doesn't work
the search icon never shows up while I try to run it
can someone suggest what to do?

in activity_action.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:(YOUR_PROJECT_NAME)="http://schemas.android.com/apk/res-auto"
>
<!-- Search, should appear as action button -->
<item android:id="#+id/action_search"
android:orderInCategory="100"
android:icon="#drawable/ic_action_search"
android:title="#string/action_search"
YOUR_PROJECT_NAME:showAsAction="always" />
