Question

我想在我的listview中添加getPackageManager的应用程序图标。我尝试过类似的东西：

try {
            // Icon
            Drawable icon = pm.getApplicationIcon(info.processName);
            Drawable default_icon = pm.getDefaultActivityIcon();

            CharSequence c = pm.getApplicationLabel(pm.getApplicationInfo(info.processName, PackageManager.GET_META_DATA));
            Log.w("LABEL", "Name" + c.toString());
            String pName = info.processName;
            adapter.add(icon + c.toString().toUpperCase() + "\n" + info.processName);
          }

但它只返回一个字符串。如果可能，我希望图标不是字符串..是否可能？

在listview适配器中使用此行来获取应用程序图标

  PackageInfo packageInfo = (PackageInfo) getItem(position);
    Drawable appIcon =  packageManager.getApplicationIcon(packageInfo.applicationInfo);
    String appName = packageManager.getApplicationLabel(
            packageInfo.applicationInfo).toString();
    appIcon.setBounds(0, 0, 40, 40);
    holder.apkName.setCompoundDrawables(appIcon, null, null, null);
    holder.apkName.setCompoundDrawablePadding(15);
    holder.apkName.setText(appName);
