Question

我正在尝试获取线性布局并将其添加到自定义列表视图中。但它给了我错误。＆＃34;指定的孩子已经有父母。您必须先在孩子的父母身上调用removeView（）＆＃34;

    public View getView(int position, View convertView, ViewGroup parent) {

     LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
     View rowView = inflater.inflate(R.layout.emoji_chat_custom_list, null);
     Emoji_chat_list_item item = dataSet.get(position);
     LinearLayout linear = (LinearLayout) rowView.findViewById(R.id.linear);
     // ImageView imageView = (ImageView) rowView.findViewById(R.id.icon);
     // TextView textView = (TextView) rowView.findViewById(R.id.name);
     // imageView.setImageResource(item.getId());
     //textView.setText(item.getName());
     //linear.addView(linear);
     //  linear =     (LinearLayout)convertView.findViewById(R.id.inhorizontalscrollview);
     linear.addView(item.getlayout());
     //       return rowView;
       return rowView ;
}

这是自定义xml文件

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:orientation="horizontal"
 android:id="@+id/linear">
</LinearLayout>

这是主要的xml文件

<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"

    <LinearLayout

    <TableRow

                <ImageView

                    android:layout_height="wrap_content"
                    android:src="@drawable/ab"
                    />
                <ImageView
                    android:id="@+id/imageview3"

                <ImageView
                    android:id="@+id/imageview4"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:src="@drawable/abcd"
                    />


            </TableRow>
        </TableRow>
    </TableRow>

    <TableRow
        android:layout_width="match_parent"
        android:layout_height="match_parent"></TableRow>

    <TableRow
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    </TableRow>
</TableLayout>

我想要做的是我想选择图像并将其置于线性布局中。我已经完成了..但下一个目标是我想采用该布局并将其放在自定义列表视图中。

只有当您向父布局添加了视图并尝试在Java代码中动态添加其他视图时，才会显示此错误，然后它应该在添加新Views之前删除您的视图。

如果您的emoji_chat_custom_list.xml文件包含此

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:orientation="horizontal"
 android:id="@+id/linear">
</LinearLayout>

然后你不需要调用这个

linear.addView(item.getlayout());

如果不是，则调用

在linear.removeAllViews()

之前

linear.addView(item.getlayout());
