I am building an app with three toggle buttons. When each is pressed, it changes the textView in the same activity to three different colors. When two toggle buttons are pressed together, it changes the same textview to other colors, and when all three are pressed together, it changes the textview to white. How can i do this? i tried using switch statement, and if (isChecked), but it had errors
This is my MainActivity.java file
import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.CompoundButton;
import android.widget.TextView;
import android.widget.ToggleButton;
public class MainActivity extends Activity {
ToggleButton redtoggleButton;
ToggleButton bluetoggleButton;
ToggleButton greentoggleButton;
TextView june;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
redtoggleButton=(ToggleButton)findViewById(R.id.toggleButton);
bluetoggleButton=(ToggleButton)findViewById(R.id.toggleButton2);
greentoggleButton=(ToggleButton)findViewById(R.id.toggleButton3);
june=(TextView)findViewById(R.id.textView);
if (redtoggleButton.isChecked()){
june.setTextColor(Color.RED);
}else if (bluetoggleButton.isChecked()){
june.setTextColor(Color.BLUE);
}else if (greentoggleButton.isChecked()){
june.setTextColor(Color.GREEN);
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
and my activity_main.xml
