我有从网络获取一些数据并将其显示在屏幕上的活动。 我使用滚动视图,因为它是长文本,我也想为不同的数据使用不同的文本样式,所以我使用了几个不同样式的textView并在活动屏幕上显示它,我的问题是滚动视图可以处理只有一个视图,所以如何使用滚动来显示不同风格的文本视图,我试图将LinearLayout添加到scrollView中,并将代码中的所有textViews动态添加到此LinearLayout中,但我收到异常 - 滚动视图只能托管一个直接的孩子。将不同的TextView添加到ScrollView中
下面的代码:
/** this is the function, which called from the onClick method.
wanted data object contains 2 strings title message and the message itself.
When debug the code i can see that there's two String values in each loop.
but i cant add the linearLayout to my scrollView - exception ScrollView can host only one direct child */
private void showResult(ArrayList<WantedData> result) {
// TODO Auto-generated method stub
TextView title;
TextView data;
scrollLayout = (LinearLayout) findViewById(R.id.LlScrollView);
for (WantedData curr : result) {
if (curr.getTitle() == null) {
break;
}
title = new TextView(this);
title.setText(curr.getTitle());
scrollLayout.addView(title, LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT);
data = new TextView(this);
data.setText(curr.getData());
scrollLayout.addView(data, LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
}
scroll.addView(scrollLayout, LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
//at the onCreate method - scroll = (ScrollView) findViewById(R.id.SvShowTextFromServer);
}
