Question

So I generated some button. The numbers it depends on the user (when clicked a button, create a new one).

This is how I made it:

   RelativeLayout layout = (RelativeLayout) findViewById(R.id.layoutcprompt);
    RelativeLayout.LayoutParams OBJ = new RelativeLayout.LayoutParams (140,80);
    if ((commandsi%6)==0) {adjust=adjust+86; commandsi=1;}
    OBJ.leftMargin =(140*(commandsi-1))+10;
    OBJ.topMargin =250+adjust;
    Button command = new Button(this);
    command.setLayoutParams(OBJ);
    command.setId(ID);
    command.setText(edittxt.getText().toString());
    edittxt.setText("");
    command.setBackgroundResource(R.drawable.costum_button);
    command.setTextColor(Color.WHITE);
    command.setTextSize(14);
    layout.addView(command);
    command.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            Button b = (Button)view;
            scommand=b.getText().toString();
        }
    });
    command.setVisibility(View.VISIBLE);

I want to remove/delete them, but I don’t know how…. I gave them a unique id, but I still dunno how can I remove them :/

I cannot comment another post, but using

command = new Button(this)

might involve an implicit memory Leak on this! (which can be the Activity). Rather use Context object. Or remove the button at least.

Then because you have the parent of your Button. Just remove it:

ViewGroup layout = (ViewGroup) findViewById(R.id.layoutcprompt);
View command = layout.findViewById(ID);
layout.removeView(command);
