<ToggleButton> onClickListener - changing drawable back to default

Image
By User



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

    }

    dummy solution

    Keep a boolean somewhere to save the state

    boolean isPressed = false;
    @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) {
    minuskugle = (Button) findViewById(R.id.bBallhole);
    if(!isPressed)
    minuskugle.setBackgroundResource(R.drawable.redballinhole);
    else
    minuskugle.setBackgroundResource(R.drawable.yourotherdrawable);
    isPressed = !isPressed;
    }
    });
    }

Slow Android emulator

By User
I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?
