获取在设备上运行的应用程序图标

Question

我有一个列表活动,显示设备中所有正在运行的应用程序.它显示所有应用程序的默认图标.但我需要为列表中的每个应用程序获取实际应用程序图标.

public class ApplicationList extends ListActivity {
DataHelper dh;
ImageView vi;
private Drawable icon;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.applist);
    dh = new DataHelper(getApplicationContext());

    PackageManager pm = this.getPackageManager();

    Intent intent = new Intent(Intent.ACTION_MAIN, null);
    intent.addCategory(Intent.CATEGORY_LAUNCHER);

    Log.d("Test1", "INSERTING APP LIST TO SERVER DB");
     List<ResolveInfo> list = pm.queryIntentActivities(intent, PackageManager.PERMISSION_GRANTED);
     ArrayList<String> applist = new ArrayList<String>();

     for(ResolveInfo rInfo: list){

        applist.add(rInfo.activityInfo.applicationInfo.loadLabel(pm).toString() );
    }


    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
            R.layout.installedapp, R.id.textView1, applist);
    setListAdapter(adapter);
}

试试这样

List<PackageInfo> packs = getPackageManager().getInstalledPackages(0);
 Drawable[] icons=new Drawable[packs.size];
for(int i=0;i<packs.size();i++) {
    PackageInfo p = packs.get(i);
    icons[i]= p.applicationInfo.loadIcon(getPackageManager());
 }
