import android.app.Activity;  
import android.content.Intent;  
import android.view.Menu;  
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);  
            }  
              
        });  
    }  
  
    @Override  
    public boolean onCreateOptionsMenu(Menu menu) {  
        // Inflate the menu; this adds items to the action bar if it is present.  
        getMenuInflater().inflate(R.menu.activity_main, menu);  
        return true;  
    }  
      
}
