获取手机的所有app的列表，为何app名字取不出来？

Question

List<PackageInfo> appListInfo=context.getPackageManager()
.getInstalledPackages(0);
for (PackageInfo p : appListInfo) {
    System.out.println(p.applicationInfo.name); 
     System.out.println(p.applicationInfo.packageName); 
}
用这种做法很奇怪，只能取出所有包名，取不出来程序的名字~求解

问题补充，这是详细代码
package com.zhang7nan.getAppList;import java.util.List;import org.json.JSONArray;
import org.json.JSONObject;import android.app.Activity;
import android.content.pm.PackageInfo;
import android.os.Bundle;public class GetAppList extends Activity {
    
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        try {
     List<PackageInfo> appListInfo = this.getPackageManager()
     .getInstalledPackages(0);
     JSONArray ja = new JSONArray();
     for (PackageInfo p : appListInfo) {
     if (p.applicationInfo.uid > 10000) {
     JSONObject jo = new JSONObject();
     jo.put("label", p.applicationInfo.name);
     jo.put("packageName", p.applicationInfo.packageName);
     ja.put(jo);
     }
    
    
     }
     System.out.println(ja);
} catch (Exception e) {
// TODO: handle exception
}    }
}
这是得到的结果02-23 15:49:21.500: INFO/System.out(9884): [{"packageName":"com.android.soundrecorder"},{"packageName":"com.android.alarmclock"},{"packageName":"com.android.sdksetup"},{"packageName":"com.android.launcher"},{"packageName":"com.google.android.providers.enhancedgooglesearch"},{"packageName":"com.gameloft.android.ANMP.GloftAsphalt5.asphalt5"},{"packageName":"com.android.contacts"},{"packageName":"com.zhang7nan.android"},{"packageName":"com.android.inputmethod.latin"},{"packageName":"irdc.ex03_19"},{"packageName":"com.android.calculator2"},{"packageName":"com.zhang7nan.getAppList"},{"packageName":"com.android.htmlviewer"},{"packageName":"com.androidbook.layout"},{"packageName":"irdc.EX05_04"},{"packageName":"com.android.browser"},{"packageName":"com.android.customlocale"},{"packageName":"com.android.music"},{"packageName":"com.android.netspeed"},{"packageName":"com.android.providers.userdictionary"},{"packageName":"com.android.inputmethod.pinyin"},{"packageName":"android.tts"},{"packageName":"com.android.providers.media"},{"packageName":"com.android.globalsearch"},{"packageName":"com.wd.AndroidDaemon"},{"packageName":"com.android.fallback"},{"packageName":"com.gameloft.android.GAND.GloftBia2.bia2"},{"packageName":"com.android.gesture.builder"},{"packageName":"org.lee.android"},{"packageName":"android.tether"},{"packageName":"com.android.providers.contacts"},{"packageName":"com.android.providers.applications"},{"packageName":"com.android.providers.drm"},{"packageName":"com.android.term"},{"packageName":"com.android.development"},{"packageName":"com.android.packageinstaller"},{"packageName":"com.svox.pico"},{"packageName":"com.android.camera"},{"packageName":"jp.co.omronsoft.openwnn"},{"packageName":"com.android.email"},{"packageName":"com.wandoujia.wandouapp"},{"packageName":"com.android.spare_parts"},{"packageName":"com.android.providers.downloads"}]

Answer 2

楼主用这句：
                    jo.put("packageName", p.applicationInfo.loadLabel(this.getPackageManager()));
就可以看到结果了。
