在运行时android构建布局
|
我有一个复杂的xml布局，其中包含列表视图。.列表视图中的一行包含几个文本字段，它们均匀分布。我正在使用textview来存储文本，然后最终将所有项目添加到该行中……它的工作非常正常。
但是现在我有这样的情况，在不确定的情况下，我可能会从Web服务获取多少文本字段。因此，我需要在运行时动态创建textview，填充它们，然后将其插入列表。
无论如何在运行时声明，添加和填充新的textview字段？
还是有实现两个字段之间的间距？

ViewGroup.LayoutParams.WRAP_CONTENT, //Width of the view
ViewGroup.LayoutParams.WRAP_CONTENT));//Height of the view
textView.setId(i);
row.add??
}
}
setContentView(R.layout.main);
headerList.add(new Header(\"Symbol\",\"Quantity\",\"Price\",\"Price Yesterday\",\"52 Week High\",\"52 Week Low\",\"Change\",\"Days Gain\",\"Days Gain %\",\"Returns\"));
Header[] tmpHeaderList = headerList.toArray(new Header[headerList.size()]);
ArrayAdapter<Header> headerAdapter = new HeaderAdapter(this,R.layout.twoway_header_view,tmpHeaderList);
headerListView.setAdapter(headerAdapter);
