MainActivity:
package com.home.getsysapp; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; import android.app.Activity; import android.content.pm.ApplicationInfo; import android.content.pm.PackageInfo; import android.os.Bundle; import android.widget.ListView; import android.widget.SimpleAdapter; public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ListView listView = new ListView(this); List<Map<String, String>> list = getSysApps(); SimpleAdapter adapter = new SimpleAdapter(this, list, android.R.layout.simple_list_item_2, new String[] { "appname", "pname" }, new int[] { android.R.id.text1, android.R.id.text2, }); listView.setAdapter(adapter); setContentView(listView); } /** * 获取系统apps * * @return */ private List<Map<String, String>> getSysApps() { List<Map<String, String>> list = new ArrayList<Map<String, String>>(); Map<String, String> map = null; List<PackageInfo> packs = getPackageManager().getInstalledPackages(0); for (PackageInfo p : packs) { ApplicationInfo appInfo = p.applicationInfo; // 为0表示非系统的,为1表示系统的 if ((appInfo.flags & ApplicationInfo.FLAG_SYSTEM) > 0) { map = new HashMap<String, String>(); String appName = appInfo.loadLabel(getPackageManager()) .toString(); String pname = appInfo.packageName; map.put("appname", appName); map.put("pname", pname); list.add(map); } } return list; } }
