我想知道如何從應用程序中加載drawables或圖標及其應用程序名稱和活動。我看了很多已經可用的例子，但不知道如何在這裏實現它們。如果任何人都可以指導我，那會很棒。如何在android listview中加載帶有應用程序名稱的可繪製圖標
public void loadApps() {
final Intent main=new Intent(Intent.ACTION_MAIN, null);
final PackageManager pm = getPackageManager();
int i=0;
int j=0;
String tmpNick="";
if(pkg.Name.size()!=0) {pkg.Name.clear(); pkg.Activity.clear(); pkg.Nick.clear();}
switch(checkedRadioButton) {
case 0:
// LAUCHABLES VARIANT OF LOAD APPS
for(i=0; i<pkgExtra.Name.size(); i++ )
{
pkg.Name.add(pkgExtra.Name.get(i));
pkg.Nick.add(pkgExtra.Nick.get(i));
pkg.Activity.add(pkgExtra.Activity.get(i));
}
main.addCategory(Intent.CATEGORY_LAUNCHER);
final List<ResolveInfo> launchables=pm.queryIntentActivities(main, 0);
for(ResolveInfo launchable : launchables)
{
if (ItemNumInHide(launchable.activityInfo.name)==-1)
{
pkg.Name.add(launchable.activityInfo.packageName);
pkg.Activity.add(launchable.activityInfo.name);
pkg.Nick.add(launchable.activityInfo.loadLabel(pm).toString());
}
}
break;
case 1:
final List<ResolveInfo> launchables2=pm.queryIntentActivities(main, 0);
)
int length=0;
for(ResolveInfo launchable : launchables2)
{
String[] tmpSplit = new String[10];
//acInfo=launchable.activityInfo;
tmpSplit=launchable.activityInfo.name.split("\\.");
length=tmpSplit.length;
pkg.Name.add(launchable.activityInfo.packageName);
pkg.Activity.add(launchable.activityInfo.name);

tmpNick=tmpSplit[1];

tmpNick=tmpNick + ":" + tmpSplit[j];

pkg.Nick.add(tmpNick);
