android删除动态生成的按钮

Question

实现生成一些button，数量取决于用户（用户点击按钮，就会生成一个）

具体代码:

 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);

现在还要实现移除这些button，我给每个都有单独的id，但是不知道怎么移除:/。

谢谢。

Answer 1

ViewGroup layout = (ViewGroup) command.getParent();
if(null!=layout) //for safety only  as you are doing onClick
layout.removeView(command);

试试这个。
