【中文标题】在 Android 中,如何设置 ListView 项的高度和宽度?【英文标题】:In Android, how can I set a ListView item's height and width? 【发布时间】:2011-03-13 17:25:27 【问题描述】:我想创建一个界面,它有一个或两个列表视图,最终跨越整个屏幕,有两行。如何更改它们的高度,使它们垂直占据屏幕的 50%?
如果是这样,我很想知道如何做到这一点,无论方向如何。
关于宽度;假设我有两个列表视图,每个视图都有一行。如上所述,它们跨越整个屏幕。下面的列表视图中有两个可点击的项目,每个项目占据屏幕空间的 50%,水平。
这可能吗?如果有,怎么做?

【参考方案1】:您好,下面的代码将使用 full 创建一个界面,该界面具有一个或两个列表视图,最终跨越整个屏幕,两行。 Java文件如下,
public class DoubleListView extends Activity
ListView listView,listView2;
String[] titles = "List 1 title1","List 1 title2","List 1 title3","List 1 title4","List 1 title5","List 1 title6","List 1 title7","List 1 title8","List 1 title9";
String[] titles2 = "List 2 title1","List 2 title2","List 2 title3","List 2 title4","List 2 title5","List 2 title6","List 2 title7","List 2 title8","List 2 title9";
WindowManager wm;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
wm = (WindowManager)getSystemService(Context.WINDOW_SERVICE);
int height = wm.getDefaultDisplay().getHeight();
listView = new ListView(this);
listView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,height/2-15));
listView.setAdapter(new CustomListAdapetr(this, titles));
listView2 = new ListView(this);
listView2.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,height/2));
listView2.setAdapter(new CustomListAdapetr(this, titles2));
((LinearLayout)findViewById(R.id.mailLayout)).addView(listView);
((LinearLayout)findViewById(R.id.mailLayout)).addView(listView2);
public class CustomListAdapetr extends BaseAdapter
private Context mContext;
private String[] list;
public CustomListAdapetr(Context context, String[] titles)
mContext = context;
list = titles;
@Override
public int getCount()
// TODO Auto-generated method stub
return list.length;
@Override
public Object getItem(int position)
// TODO Auto-generated method stub
return list[position];
@Override
public long getItemId(int position)
// TODO Auto-generated method stub
return position;
@Override
public View getView(int position, View convertView, ViewGroup parent)
CustomView cv;
if (convertView == null)
cv = new CustomView(mContext,""+list[position]);
else
cv = (CustomView) convertView;
cv.setTitle(list[position]);
return cv;
private class CustomView extends LinearLayout
public CustomView(Context context, String itemName)
super(context);
this.setOrientation(HORIZONTAL);
// Here we build the child views in code. They could also have
// been specified in an XML file.
mTitle = new TextView(context);
mTitle.setText(itemName);
mTitle.setTextSize(25);
addView(mTitle, new LinearLayout.LayoutParams(200, LayoutParams.WRAP_CONTENT));
/** * Convenience method to set the title of a SpeechView */
public void setTitle(String title)
mTitle.setText(title);
/** * Convenience method to set the dialogue of a SpeechView */
private TextView mTitle;
xml文件是,
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_
android:layout_
android:id="@+id/mailLayout">
</LinearLayout>
试试这个以获得你想要的界面。
