我想在android中获取文件缩略图,如APK文件或图像文件,我怎样才能找到每个缩略图,我的意思是APK图标的图像或相机图像的缩略图......
多谢
参考这个链接
private ArrayList<String> getInstalledApps(Context context){
ArrayList<Drawable> results = new ArrayList<Drawable>();
PackageManager pm = context.getPackageManager();
Intent intent = new Intent(Intent.ACTION_MAIN, null);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
List list = pm.queryIntentActivities(intent, PackageManager.PERMISSION_GRANTED);
for (ResolveInfo rInfo : list) {
results.add(rInfo.activityInfo.applicationInfo.loadIcon(pm);
}
return results;
}
