android - 指定的 child 已经有一个 parent 。当我做 layout.addView(button, params);

Question

当您尝试在 View 中添加 mdescrition 时

mDescriptHelp = (TextView)view.findViewById(R.id.id_descript_help); 
mDescriptHelp.setTypeface(mFontUtils.getBentonSansMediumFont());

TelephonyManager manager = 
         (TelephonyManager)mActivity.getSystemService(Context.TELEPHONY_SERVICE);

if(manager.getPhoneType() == TelephonyManager.PHONE_TYPE_NONE){

    FrameLayout.LayoutParams params = 
                new FrameLayout.LayoutParams(LayoutParams.WRAP_CONTENT, 
                                             LayoutParams.WRAP_CONTENT);
    params.setMargins(800, 290, 10, 0);
    layout.addView(mDescriptHelp, params);
}

我的错误是

03-16 06:27:07.452: E/AndroidRuntime(7233): java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

我不明白这个错误。任何想法？我希望有人能帮助我。

改变这一行

layout.addView(mDescriptHelp, params);

到

mDescriptHelp.setLayoutParams(params);

我认为是这样。
