- public class MainActivity extends Activity {
- private ToggleButton toggleButton1, toggleButton2;
- private Button buttonSubmit;
- @Override
- protected void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.activity_main);
- addListenerOnButtonClick();
- }
- public void addListenerOnButtonClick(){
- //Getting the ToggleButton and Button instance from the layout xml file
- toggleButton1=(ToggleButton)findViewById(R.id.toggleButton1);
- toggleButton2=(ToggleButton)findViewById(R.id.toggleButton2);
- buttonSubmit=(Button)findViewById(R.id.button1);
- //Performing action on button click
- buttonSubmit.setOnClickListener(new OnClickListener(){
- @Override
- public void onClick(View view) {
- StringBuilder result = new StringBuilder();
- result.append("ToggleButton1 : ").append(toggleButton1.getText());
- result.append("\nToggleButton2 : ").append(toggleButton2.getText());
- //Displaying the message in toast
- Toast.makeText(getApplicationContext(), result.toString(),Toast.LENGTH_LONG).show();
- }
- });
- }
- @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;
- }
- }
