Context Menu
Android context menu appears when user press long click on the element. It is also known as floating menu.
It affects the selected content while doing action on it.
It doesn't support item shortcuts and icons.
Android Context Menu Example
Let's see the simple example of context menu in android.
activity_main.xml
Drag one listview from the pallete, now the xml file will look like this:
File: activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="example.javatpoint.com.contextmenu.MainActivity">
<ListView
android:layout_width="368dp"
android:layout_height="495dp"
android:id="@+id/listView"
android:layout_marginEnd="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="example.javatpoint.com.contextmenu.MainActivity">
<ListView
android:layout_width="368dp"
android:layout_height="495dp"
android:id="@+id/listView"
android:layout_marginEnd="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
main_menu.xml
Create a separate menu_main.xml file in menu directory for menu items.
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/call"
android:title="Call" />
<item android:id="@+id/sms"
android:title="SMS" />
</menu>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/call"
android:title="Call" />
<item android:id="@+id/sms"
android:title="SMS" />
</menu>
Activity class
Let's write the code to display the context menu on press of the listview.
File: MainActivity.java
package example.javatpoint.com.contextmenu;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.ContextMenu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
ListView listView;
String contacts[]={"Ajay","Sachin","Sumit","Tarun","Yogesh"};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView=(ListView)findViewById(R.id.listView);
ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,contacts);
listView.setAdapter(adapter);
// Register the ListView for Context menu
registerForContextMenu(listView);
}
@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo)
{
super.onCreateContextMenu(menu, v, menuInfo);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_main, menu);
menu.setHeaderTitle("Select The Action");
}
@Override
public boolean onContextItemSelected(MenuItem item){
if(item.getItemId()==R.id.call){
Toast.makeText(getApplicationContext(),"calling code",Toast.LENGTH_LONG).show();
}
else if(item.getItemId()==R.id.sms){
Toast.makeText(getApplicationContext(),"sending sms code",Toast.LENGTH_LONG).show();
}else{
return false;
}
return true;
}
}
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.ContextMenu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
ListView listView;
String contacts[]={"Ajay","Sachin","Sumit","Tarun","Yogesh"};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView=(ListView)findViewById(R.id.listView);
ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,contacts);
listView.setAdapter(adapter);
// Register the ListView for Context menu
registerForContextMenu(listView);
}
@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo)
{
super.onCreateContextMenu(menu, v, menuInfo);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_main, menu);
menu.setHeaderTitle("Select The Action");
}
@Override
public boolean onContextItemSelected(MenuItem item){
if(item.getItemId()==R.id.call){
Toast.makeText(getApplicationContext(),"calling code",Toast.LENGTH_LONG).show();
}
else if(item.getItemId()==R.id.sms){
Toast.makeText(getApplicationContext(),"sending sms code",Toast.LENGTH_LONG).show();
}else{
return false;
}
return true;
}
}
Output:
Output after long press on the listview.
Output after clicking on the context menu.
