如何在不在listview中显示字幕时如何在listitem中对齐标题
我有listview和两个textview“title”和“subtitle”作为listitem的一部分。现在在一些列表项目中我只显示“标题”而不是“副标题”，在这种情况下如何在中心对齐“标题”？下面是截图和xml代码
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#ffffff"
android:padding="8dp">
<LinearLayout
android:id="@+id/Text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_marginLeft="15dip">
<TextView
android:id="@+id/list_item_entry_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="marquee"
android:textColor="#666666"
android:fadingEdge="horizontal"
android:singleLine="true"
android:textSize="18sp"
/>
<TextView
android:id="@+id/list_item_entry_summary"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#666666"
android:gravity="center"
android:layout_alignLeft="@id/list_item_entry_title"
android:layout_below="@id/list_item_entry_title"
android:singleLine="true"
android:textSize="13sp"
/>
</LinearLayout>
<ImageView
android:id="@+id/lefticons"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginRight="15dip"
android:src="@drawable/icon" />
<ImageView
android:id="@+id/righticons"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:paddingRight="10dip"
android:src="@drawable/icon" />
</RelativeLayout>
以编程方式我尝试设置setMargins，但它搞砸了。还有其他方法吗？
if (ei.getTitle().contentEquals("TV Results")) {
rightimageicon.setImageResource(R.drawable.arrow);
leftimageicon.setVisibility(View.GONE);
subtitle.setVisibility(View.GONE);
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams)title.getLayoutParams();
params.setMargins(5, 5, 5, 5); //substitute parameters for left, top, right, bottom
title.setLayoutParams(params);
}
完整的getView代码：
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
final Item i = items.get(position);
if (i != null) {
if(i.isSection()){
SectionItem si = (SectionItem)i;
v = vi.inflate(R.layout.list_item_section, null);
v.setOnClickListener(null);
v.setOnLongClickListener(null);
v.setLongClickable(false);
final TextView sectionView = (TextView) v.findViewById(R.id.list_item_section_text);
sectionView.setText(si.getTitle());
}else{
EntryItem ei = (EntryItem)i;
v = vi.inflate(R.layout.list_item_entry_settings, null);
final TextView title = (TextView)v.findViewById(R.id.list_item_entry_title);

尝试使用 RelativeLayout ，当字幕消失时，title将填充RelativeLayou。
