# Button Controls in Android Application

In this article I am going to explain how to create and use a button control in an Android Application. I am going to create three button (New, Save, Print), when a user clicked on the button the toast message will be display.\

· Start a New Project, named ButtonDemo.

· Open res/values/strings.xml and add a string in the resources tag.

```
<string name="onClick">onClick</string>
```

· Open **res/layout/main.xml** and add three button as shown below:

```
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:orientation="horizontal"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent">
     <Button android:id="@+id/btnNew"
               android:layout_width="150px"
               android:layout_height="wrap_content"
               android:onClick="onClick" />
     <Button android:id="@+id/btnSave"
               android:layout_width="150px"
               android:layout_height="wrap_content"
               android:onClick="onClick" />
     <Button android:id="@+id/btnPrint"
               android:layout_width="150px"
               android:layout_height="wrap_content"
               android:onClick="onClick" />
</LinearLayout>
```

· Open a activity file and add the following code in that activity:

```
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class FormActivity  extends Activity {

     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.main);
         Button btnNew=(Button)findViewById(R.id.btnNew);
         Button btnSave=(Button)findViewById(R.id.btnSave);
         Button btnPrint=(Button)findViewById(R.id.btnPrint);
         btnNew.setText("New");
         btnSave.setText("Save");
         btnPrint.setText("Print");
    }
     public void onClick(View v) {
     switch(v.getId())
    {
      case R.id.btnNew:
     Toast.makeText(FormActivity.this,  "You clicked New", Toast.LENGTH_SHORT).show();
      break;

      case R.id.btnSave:
     Toast.makeText(FormActivity.this,  "You clicked Save",Toast.LENGTH_SHORT).show();

      break;

      case R.id.btnPrint:
     Toast.makeText(FormActivity.this,  "You clicked Print",Toast.LENGTH_LONG).show();

      break;
     }
   }
}
```

· Run the application

Your output should look like below:
