Question

I’m creating buttons dynamically …

for(int i=0; i<colSize;i++){
    final Button btn = new Button(this);    
    btn.setText(SectionName[i]);        
    btn.setTextSize(10);
    btn.setPadding(8, 3,8, 3);   
    btn.setTextColor(Color.WHITE);
    btn.setTypeface(Typeface.SERIF, Typeface.BOLD);

    btn.setOnClickListener(new OnClickListener() {  
        @Override
        public void onClick(View v) {               
            //***Every time that I click my button is selected !:)
            btn.setSelected(true);      
        }                   

     });  

    }

But how could I deselect the other buttons that were selected, I just want one Button selected! 🙂

Answer 1

Declare a variable to store the Id of the Clicked Button ::

private int EnabledButton;

set an ID on every button when are created ::

btn.setId(i);

or a tag ::

btn.setTag(i);   

then in that Listener get the “EnabledButton”, and call a function to deselect the other buttons::

 btn.setOnClickListener(new OnClickListener() {  
        @Override
        public void onClick(View v) {                 
        EnabledButton=btn.getId();
        DeselectButtons();        
        btn.setSelected(true);      
    }                   

 });  

The Function to deselect the other Buttons ::

public void DeselectButtons() {
    for(int i=0; i<NumberofButtons;i++){            
                    if (EnabledButton!= i)
        this.findViewById(i).setSelected(false);
    }           

}
