In this project we are making app where user can call from our app rather than using default calling app
Code:-
MainActivity:-
package com.example.call;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.ImageButton;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
EditText etNumber;
ImageButton btCall;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
etNumber = findViewById(R.id.et_number);
btCall = findViewById(R.id.bt_call);
btCall.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
String phone = etNumber.getText().toString();
if(phone.isEmpty()){
Toast.makeText(getApplicationContext(), "Enter Your Number", Toast.LENGTH_SHORT).show();
}else{
String s = "tel:"+ phone;
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData((Uri.parse(s)));
startActivity(intent);
}
}
});
}
}
