我的代码有问题（它不按我想要的方式工作）。我有一组图像（图像的数量可能会有所不同）。所以我把它们放在网格视图中。下面是我的XML：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/relativeLayoutRest" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button android:layout_alignParentLeft="true"
android:layout_width="50px" android:id="@+id/adbutton"
android:layout_height="fill_parent" android:text="\n\nR\nE\nK\nL\nA\nML\nA\nR\n\n"
android:textStyle="bold">
</Button>
<ScrollView android:id="@+id/scrollViewRest"
android:paddingLeft="100px" android:layout_width="wrap_content"
android:layout_height="fill_parent">
<LinearLayout android:id="@+id/linearLayout1"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:orientation="horizontal">
<GridView android:id="@+id/gridViewRest" android:gravity="center"
android:stretchMode="columnWidth" android:horizontalSpacing="50px"
android:layout_width="wrap_content" android:verticalSpacing="50px"
android:columnWidth="150px" android:layout_height="fill_parent"
android:numColumns="auto_fit"></GridView>
</LinearLayout>
</ScrollView>
</RelativeLayout>
对于gridview来说 android：columnWidth =“150px”android：layout_height =“fill_parent” 它只是填满了屏幕的一半。但是当它的800像素它工作正常。 由于系统是动态的，我不希望每次安装时都使用XML。 我需要这方面的帮助，以下是我的java文件以防万一：
public class RestListActivity extends Activity{
//ImageButton [] buttons;
RelativeLayout rl;
int restCount=0;
Resources a;
int resIndex=0;
boolean resFound=false;
int last;
int resCount=0;

@Override
public void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.restlist);
rl = (RelativeLayout) findViewById(R.id.relativeLayoutRest);
Log.i("asd","asd");
a=this.getResources();
int i=0x7f020000;
boolean done=true;
Log.i("asd","asd");
ArrayList <Integer> restLogoIDs=new ArrayList<Integer>();
try
{
for (i=0x7f020000 ;done&&i<0x7f020040;i++)
{
Log.i("rest buttons","----"+i);
String name=a.getResourceName(i);
name=name.substring(name.indexOf(':')+1);
name=name.substring(9);
if(name.startsWith("rest"))
{
restLogoIDs.add(new Integer(i));
if(!resFound)
{
resIndex=i;
resFound=true;
}
Log.i("rest buttons",name);
resCount++;
}

orderButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {

startActivity(i);
