Android的列表视图宽度概率 [英] Android Listview width prob

问题描述

下面是屏幕的主要布局：

Here is the main layout for a screen:

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/splashContent"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/splashscreenbg">
    <TableRow
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight=".008"
        android:gravity="center"
        android:background="@drawable/mbstabtitle_bg"
        android:paddingTop="5dip" 
        android:paddingBottom="5dip">
        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:gravity="center" >
            <TextView
                android:id="@+id/mbstabtitle_bg"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textSize="20sp"
                android:textStyle="bold"
                android:text="Please Select Your Location"
                android:textColor="#FFFFFF">
            </TextView>     
        </LinearLayout>
    </TableRow>
    <TableRow
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:gravity="top"
        android:layout_weight=".99">
        <ListView
            android:id="@+id/locationlist"
            android:background="#7B0326"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent">
        </ListView>
    </TableRow>
</TableLayout>

这里是用来填充列表视图的适配器。

And here is the Adapter used to populate the listview.

class LocationAdapter extends BaseAdapter {
        private Activity activity;
        private String[][] data;
        private LayoutInflater inflater=null;

        public LocationAdapter(Activity a, String[][] d) {
            activity = a;
            data=d;
            inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        }

        public int getCount() {
            return data.length;
        }

        public Object getItem(int position) {
            return position;
        }

        public long getItemId(int position) {
            return position;
        }

        public View getView(int position, View convertView, ViewGroup parent) {
            View vi=convertView;
            ViewHolder holder;
            if(convertView==null){
                vi = inflater.inflate(R.layout.locationitem, null);
                holder=new ViewHolder();
                holder.locationName=(TextView)vi.findViewById(R.id.locationName);

                vi.setTag(holder);
                if(position%2 == 0)
                    vi.setBackgroundColor(0xFF4D0418);
                else
                    vi.setBackgroundColor(0xFF7B0326);
            }
            else
                holder=(ViewHolder)vi.getTag();

            holder.locationName.setText(data[position][1]);          

            vi.setId(Integer.parseInt(data[position][0]));

            return vi;
        }

        class ViewHolder {
            TextView locationName;
        }
    }

这是项目（locationitem.xml）的XML。

And here is the xml for the items(locationitem.xml).

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="horizontal"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:gravity="center_vertical">
    <ImageView
        android:id="@+id/centerbullet"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="3dip"
        android:src="@drawable/centerbullet"/>
    <TextView android:id="@+id/locationName" 
        android:layout_width="match_parent"
        android:layout_height="wrap_content" 
        android:textStyle="bold"
        android:paddingLeft="10dip"
        android:text="hello hello egele efsdffgxnd"
        android:textSize="15dip" />
</LinearLayout>

现在我的问题是列表视图，并采取以显示它所需的只是最小宽度在它的项目，而我想，它需要提供的总宽度。在我的code中的问题是什么？

Now my problem is the the listview and the item in it taking just minimum width it required to display, whereas I want that it takes the total width available. What is the problem in my code?

推荐答案

的android：ListView中layout_weight =1解决了这个问题。

android:layout_weight="1" in ListView solved the problem.
