单击editText后，转到另一个edittext时完成

Question

I'm having a question where I couldn't find the answer online or know how to find it..

I have EditText xml attribute and I made an event listener to this attribute by changing the color of an underline beneath it. Is there a way when the focus is removed from this EditText (ie user click on any other element rather than this one) to remove the highlighted color for the line I colored?

On the onclick event listener? It seems weird, but I want the opposite of the onclick like onclickremove or something.

You can use the the setOnFocusChangeListener to your EditText. If lost focus,clear the color filter:

editText.setOnFocusChangeListener(new OnFocusChangeListener() {          
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (hasFocus) {
               editText.getBackground().setColorFilter(color, PorterDuff.Mode.SRC_IN);
            }
            else{                   
               editText.getBackground().clearColorFilter();
            }
        }
    });

If you want to change your view color, just add the below line in onFocusChange :

view.setBackgroundColor(Color.parseColor("#ffffff"));

Hope this helps.

You need to use setOnFocusChangedListener for this. The hasFocus determines whether the focus is removed or given to a view. It being false indicates that user has left the field.

EditText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if(hasFocus == false){
                     // change the color
                }
            }
        });
