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); } }); } } |
Output:
