How do you make a phone call from 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.
|
AndroidManifest.xml:
In the Android-Manifest.xml file, we will write the CALL_PHONE permission code.
Syntax:
File: AndroidManifest.xml:
|
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);
}
});
}
