Make phone call android

To make a phone call, the intent is used in Android.

Code: To make a phone call:

Intent callIntent = new Intent(Intent.ACTION_CALL);  
callIntent.setData(Uri.parse("tel:"+123456789));//change the number  
startActivity(callIntent);

Example:

activity_main.xml:

In the activity_main.xml file, we will drag the EditText and Button from the palette.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >
 
    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="118dp"
        android:text="Call this Number" />
 
    <EditText
        android:id="@+id/editText1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="25dp"
        android:ems="10" />
 
</RelativeLayout>

AndroidManifest.xml:

In the Android-Manifest.xml file, we will write the CALL_PHONE permission code.

Syntax:

<uses-permission android:name="android.permission.CALL_PHONE" />

File: AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.radioapp" >
 
    <uses-permission android:name="android.permission.CALL_PHONE" />
 
    <application
        android:allowBackup="true"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
 
        <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>
 
        </activity>
 
    </application>
</manifest>

Activity class:(File: MainActivity.java)

In the MainActivity.java file, we will write the code to make the phone call via intent.

package com.example.radioapp;
 
import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
 
public class MainActivity extends Activity {
    EditText edittext1;
    Button button1;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
 
        //Getting the edittext and button instance
        edittext1=(EditText)findViewById(R.id.editText1);
        button1=(Button)findViewById(R.id.button1);
 
        //Performing action on button click
        button1.setOnClickListener(new OnClickListener(){
 
            @Override
            public void onClick(View arg0) {
                String number=edittext1.getText().toString();
                Intent callIntent = new Intent(Intent.ACTION_CALL);
                callIntent.setData(Uri.parse("tel:"+number));
                startActivity(callIntent);
            }
 
        });
    }
 
 
}
