java - 列出已安装的应用程序 android

Question

如何获取已下载的已安装应用程序，而不是应用程序（如联系人、设置、相机等）。我正在使用 PackageManager，它返回整个应用程序（默认 + 下载）。

Answer 1

尝试这个：

public class AppList extends Activity {
 private ListView lView;
 private ArrayList results = new ArrayList();

 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
  lView = (ListView) findViewById(R.id.list1);
  PackageManager pm = this.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
     .loadLabel(pm).toString());
   Log.w("Installed Applications", rInfo.activityInfo.applicationInfo
     .loadLabel(pm).toString());
  } 
  lView.setAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1, results));
    }
}
