In this post we are going to learn how to create ContextMenu in Android
To Make any view to show context menu we need to register that View with below code
|
registerForContextMenu(View) |
and we can unregister with
|
unregisterForContextMenu(View) |
Let's Start
Step 1: Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project
Step 2: Updated Activity xml file with below code
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="https://schemas.android.com/apk/res/android"
xmlns:tools="https://schemas.android.com/tools"
xmlns:app="https://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical"
tools:context=".contextmenu.ContextMenuActivity">
<Button android:layout_width="wrap_content" android:layout_height="wrap_content"
android:id="@+id/btnContext" android:text="Long Press"
android:layout_gravity="center"
android:background="@color/colorPrimary"
android:textColor="@color/white"
android:minEms="9"
android:textSize="20dp"
/>
</LinearLayout>
|
Step 3: Create Menu file and add below code
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="https://schemas.android.com/apk/res/android" xmlns:app="https://schemas.android.com/apk/res-auto">
<item android:id="@+id/coupons"
android:title="Coupons"
app:showAsAction="never"></item>
<item android:id="@+id/cashback"
android:title="Cashback"
app:showAsAction="never"></item>
<item android:id="@+id/deals"
android:title="Deals"
app:showAsAction="never"></item>
</menu>

Step 4: Update Activity with below code
package com.rrtutors.androidsamples.contextmenu
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import com.rrtutors.androidsamples.R
import kotlinx.android.synthetic.main.activity_context_menu.*
import android.widget.Toast
import android.view.ContextMenu
import android.view.MenuItem
import android.view.View
class ContextMenuActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(com.rrtutors.androidsamples.R.layout.activity_context_menu)
registerForContextMenu(btnContext)
btnContext
}
override fun onCreateContextMenu(menu: ContextMenu?, v: View?, menuInfo: ContextMenu.ContextMenuInfo?) {
super.onCreateContextMenu(menu, v, menuInfo)
val inflater = menuInflater
inflater.inflate(R.menu.menu, menu)
}
override fun onContextItemSelected(item: MenuItem): Boolean {
var toast: Toast? = null
when (item.getItemId()) {
R.id.coupons -> {
toast = Toast.makeText(this, "Coupons context item clicked", Toast.LENGTH_LONG)
toast!!.show()
return true
}
R.id.cashback -> {
toast = Toast.makeText(this, "Cashback context item clicked", Toast.LENGTH_LONG)
toast!!.show()
return true
}
R.id.deals -> {
toast = Toast.makeText(this, "Deals context item clicked", Toast.LENGTH_LONG)
toast!!.show()
return true
}
else -> return super.onContextItemSelected(item)
}
}
}
