我有一个复杂的xml布局,它有列表视图。列表视图中的一行包含几个均匀间隔的文本字段。我正在使用textview存储文本,然后最后将所有项目添加到行...它的工作完全正常。 但现在我有一个案例,我不确定,我可以从网络服务获得多少文本字段。因此我需要在运行时动态创建textview,填充它们然后插入列表.. 无论如何在运行时声明,添加和填充新的textview字段? 或者无论如何要实现两个字段之间的间距?

我尝试实现下面提供的解决方案(Kenny),但由于某种原因我无法将视图添加到列表中..下面是我的代码
public class HeaderAdapter extends ArrayAdapter<Header> {
final Header[] listSymbols;
private TextView textView;
private LinearLayout row;
public HeaderAdapter(Context context, int symResourceID,
Header[] objects) {
super(context, symResourceID, objects);
listSymbols = objects;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) getContext()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View row = inflater.inflate(R.layout.header_view, parent, false);
Header headerRec = listSymbols[position];
for(int i = 0 ; i < listSymbols.length;i++){
textView = new TextView(getContext());
textView.setLayoutParams(new LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT, //Width of the view
ViewGroup.LayoutParams.WRAP_CONTENT));//Height of the view
textView.setId(i);
row.add??
}
}
调用此
的主要活动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);
xml布局文件......主文件
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:orientation="vertical">
<HorizontalScrollView android:layout_width="wrap_content"
android:layout_height="wrap_content" android:scrollbars="none"
android:id="@+id/headerHv">
<ListView android:id="@+id/header_listView1"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:background="@color/white" android:cacheColorHint="#00000000"
android:smoothScrollbar="true" android:scrollbars="none" />
</HorizontalScrollView>
</LinearLayout>
定义行的模板的文件
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:orientation="horizontal"
>
<TextView android:id="@+id/headerList" android:layout_width="80dp"
android:layout_height="wrap_content" android:textColor="#000000"
android:typeface="sans" android:textStyle="normal" />
</LinearLayout>

这是我从列表中动态生成自定义按钮的方式,你可以用textViews做同样的事情:
//Setup Buttons
layout = (LinearLayout)findViewById(R.id.layoutBars);
int count = lBars.size();
for(int i = 0; i< count;i++){
final Bar b = lBars.get(i);
BarButton button = new BarButton(DDTBars.this, R.drawable.barsmall , b.getName().toUpperCase());
button.setLayoutParams(new LayoutParams(
ViewGroup.LayoutParams.FILL_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT));
button.setId(i);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//Run activity passing name of the bar to retrieve data
Intent i = new Intent(DDTBars.this, DDTBar.class);
i.putExtra("name", b.getName());
startActivity(i);
}
});
layout.addView(button);
}
所以你可以试试:
//Setup TextViews
layout = (LinearLayout)findViewById(R.id.mylayout);
int count = myTextList.size();
for(int i = 0; i< count;i++){
TextView txtView = new TextView(this);
txtView.setLayoutParams(new LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT, //Width of the view
ViewGroup.LayoutParams.WRAP_CONTENT));//Height of the view
txtView.setId(i);
layout.addView(txtView);
}

你可以在代码中完成。在循环中声明TextView并使用RelativeLayout将它们相互定位。
