Change EditText value from text to password and vice versa on ToggleButton checked

Question

I am studying programming in Android and I'm hitting an issue. I have this toggle button and when I input a text and the button is on, the text is starred (passworded, call it whatever you want) and when the button is off, the text is a text. However, I am hitting an issue and I don't see the problem. The block of code looks like:

toggleCommand.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                if(toggleCommand.isChecked()){
                    input.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);
                } else{
                    input.setInputType(InputType.TYPE_CLASS_TEXT);
                }
            }
        });

I don't see the problem. Can you tell me what did I do wrong and explain? When I turn on the application.. I type something in and it's passworded. I press the button to uncheck it and the passworded text turns into a text. I press the button again and instead of getting passworded again, the text stays normal.

Here is the working code:

toggleCommand.setOnClickListener(new OnClickListener()
    {

        @Override
        public void onClick(View arg0)
        {
            if (toggleCommand.isChecked())
            {
                input.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
            }
            else
            {
                input.setInputType(InputType.TYPE_CLASS_TEXT);
            }
        }
    });

Try this:

toggleCommand = (ToggleButton)findViewById(R.id.the_id_of_your_togglebutton) ;
toggleCommand.setOnCheckedChangeListener( new OnCheckedChangeListener() 
{
    @Override
    public void onCheckedChanged(CompoundButton toggleButton, boolean isChecked) 
    {
        if(isChecked)
        {
            input.setTransformationMethod(PasswordTransformationMethod.getInstance());
        } 
        else
        {
            input.setTransformationMethod(null);
        }
    }
});

You can read more about it on the documentation.

UPDATE

To make this kind of manipulation, you can use TransformationMethod.

So, to set the text to a hidden password, you must use PasswordTransformationMethod, and to turn it to text again, you just set the TransformationMethod to null, this way, no transformation will be applied to the text.

Hope this helps you.
