在单击按钮时动态添加布局的次数

Question

    parent = (ViewGroup) C.getParent();//c is a layout in which position i want to add view
    final int index = parent.indexOfChild(C);
    tobeadded=getLayoutInflater().inflate(R.layout.block_tobeadded_foremi,null);
    ((Button)findViewById(R.id.button88)).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            addviewcount+=1;
            LinearLayout addinglayout=new LinearLayout(MyActivity.this);
            addinglayout.setOrientation(LinearLayout.VERTICAL);
            parent.removeViewAt(index);
            addinglayout.removeAllViews();
            for(int i=0;i<addviewcount;i++)
                   addinglayout.addView(tobeadded);
            parent.addView(addinglayout, index);
        }
    });

谁能帮我知道哪里出了问题？还有其他方法吗？提前感谢！

Answer 1

您将获得一个IllegalStateException，因为您已经将子级附加到布局的根。

parent.removeViewAt(index);
addinglayout.removeAllViews();
for(int i=0;i<addviewcount;i++)
     addinglayout.addView(tobeadded);//Exception in this line
parent.addView(addinglayout, index);

假设addviewcount是2。

现在在第一次迭代中，tobeadded被附加到AddingLayout。
