super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ListView listView = (ListView) findViewById(R.id.listView1);
appInfos = getData();
AppInfoAdapter aia = new AppInfoAdapter(this);
listView.setAdapter(aia);
}
public List getData() {
List listAppInfos = new ArrayList();
PackageManager pm = getPackageManager();
Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
List resolveInfos = pm.queryIntentActivities(mainIntent,PackageManager.MATCH_DEFAULT_ONLY);
Collections.sort(resolveInfos,new ResolveInfo.DisplayNameComparator(pm));
if (listAppInfos != null) {
listAppInfos.clear();
for (ResolveInfo reInfo : resolveInfos) {
String activityName = reInfo.activityInfo.name;
String pkgName = reInfo.activityInfo.packageName;
String appLabel = (String) reInfo.loadLabel(pm);
Drawable icon = reInfo.loadIcon(pm);
Intent launchIntent = new Intent();
launchIntent.setComponent(new ComponentName(pkgName,activityName));
AppInfo appInfo = new AppInfo();
appInfo.setAppLabel(appLabel);
appInfo.setPkgName(pkgName);
appInfo.setAppIcon(icon);
listAppInfos.add(appInfo);
}
}
return listAppInfos;
}
static class ViewHoler {

TextView textView2;
}
class AppInfoAdapter extends BaseAdapter {
LayoutInflater miInflater;

}
@Override
