Question

I’ve got this ToggleButton which is supposed to change the drawables (and functions) of some other buttons upon toggling on/off.

So far i’ve only managed to make it work one way, by using this code.

    @Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    toggle = (ToggleButton) findViewById(R.id.bRedGreen);
    toggle.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            minuskugle = (Button) findViewById(R.id.bBallhole);
            minuskugle.setBackgroundResource(R.drawable.redballinhole);

        }

    });
}

How do you make it change the drawable back to default upon another click?

This works for one entry.

However if i add multiple entries it comes with an error for the “else”.

This works:

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            pluskugle = (Button) findViewById(R.id.bBallhole);
            minuskugle = (Button) findViewById(R.id.bBallhole);

            pluskegle = (Button) findViewById(R.id.bKegle);
            minuskegle = (Button) findViewById(R.id.bKegle);

        if(toggle.isChecked())
            minuskugle.setBackgroundResource(R.drawable.redballinhole);
        else
            pluskugle.setBackgroundResource(R.drawable.whiteballhole);

This doesn’t

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            pluskugle = (Button) findViewById(R.id.bBallhole);
            minuskugle = (Button) findViewById(R.id.bBallhole);

            pluskegle = (Button) findViewById(R.id.bKegle);
            minuskegle = (Button) findViewById(R.id.bKegle);

        if(toggle.isChecked())
            minuskugle.setBackgroundResource(R.drawable.redballinhole);
            minuskegle.setBackgroundResource(R.drawable.redkegle);
        else
            pluskugle.setBackgroundResource(R.drawable.whiteballhole);
            pluskegle.setBackgroundResource(R.drawable.redkegle);

Try this:

    @Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    toggle = (ToggleButton) findViewById(R.id.bRedGreen);
    toggle.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            minuskugle = (Button) findViewById(R.id.bBallhole);
            if(toggle.isChecked())
               minuskugle.setBackgroundResource(R.drawable.redballinhole);
            else
               minuskugle.setBackgroundResource(R.drawable.xy);


        }

    });
}
