<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
    minuskugle.setBackgroundResource(R.drawable.xy);


    }

    });
    }

    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;
    }
    });
    }

div not scrolling properly with slimScroll plugin

By User
I am using the slimScroll plugin for jQuery by Piotr Rochala Which is a great plugin for nice scrollbars on most browsers but I am stuck because I am using it for a chat box and whenever the user appends new text to the boxit does scroll using the .scrollTop() method however the plugin's scrollbar doesnt scroll with it and when the user wants to look though the chat history it will start scrolling from near the top. I have made a quick demo of my situation http://jsfiddle.net/DY9CT/2/ Does anyone know how to solve this problem?

Why does this javascript based printing cause Safari to refresh the page?

By User
The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth. The effect is reproduced by this fiddle: http://jsfiddle.net/fYmnB/ Clicking the print button and finishing or cancelling a print in Safari causes the screen to "go white" for a sec, which in my real website manifests itself as something "like" a reload. While running print button with, let's say, Firefox, just opens and closes the print dialogue without affecting the fiddle page in any way. Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided? P.S.: On my real site the same occurs with Chrome.
