我的code显示其安装在ListView特定权限的应用程序。我想打开的设置，你可以卸载的每个项目（应用程序）。如何做呢应用程序？

这里是打开应用程序的设置片段

 的packageName =com.wagtailapp;
    尝试{
        //打开特定的应用程序信息页面：
        意向意图=新意图（
                android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS）;
        intent.setData（Uri.parse（套餐+的packageName））;
        startActivity（意向）;
    }赶上（ActivityNotFoundException E）{
        // e.printStackTrace（）;
        //打开通用应用程序页面：
        意向意图=新意图（
                android.provider.Settings.ACTION_MANAGE_APPLICATIONS_SETTINGS）;
        startActivity（意向）;
 

这里是我的活动

 公共类MainActivity延伸活动{    ArrayList的＆LT;串GT;结果=新的ArrayList＆LT;串GT;（）;     @覆盖
       保护无效的onCreate（捆绑savedInstanceState）{
          super.onCreate（savedInstanceState）;
          的setContentView（R.layout.activity_main）;
          getInstalledApps（本）;
          ArrayAdapter适配器=新ArrayAdapter＆LT;串GT;（这一点，R.layout.activity_listview，结果）;          ListView控件的ListView =（ListView控件）findViewById（R.id.mobile_list）;
          listView.setAdapter（适配器）;
       }      私人的ArrayList＆LT;串GT; getInstalledApps（上下文的背景下）{
        软件包管理系统软件包管理系统= context.getPackageManager（）;
        清单＆LT; PackageInfo＆GT; APPLIST = packageManager.getInstalledPackages（0）;
        迭代器＆LT; PackageInfo＆GT;它= applist.iterator（）;
        而（it.hasNext（））{
            PackageInfo PK =（PackageInfo）it.next（）;
            如果（（pk.applicationInfo.flags＆放大器;！ApplicationInfo.FLAG_SYSTEM）= 0）{
                Log.v（使用互联网=系统的应用，+ pk.applicationInfo.loadLabel（软件包管理系统））;
                继续;
            }            如果（PackageManager.PERMISSION_GRANTED ==软件包管理系统.checkPermission（Manifest.permission.INTERNET，pk.packageName）||
                    PackageManager.PERMISSION_GRANTED ==软件包管理系统.checkPermission（Manifest.permission.READ_EXTERNAL_STORAG​​E，pk.packageName））
                results.add（+ pk.applicationInfo.loadLabel（软件包管理系统））;
        }        Log.v（，results.toString使用Internet =程序（））;        返回结果;
    }
}
 

解决方案

你的onCreate（）以下listView.setAdapter（适配器）在

本贴code;

  listView.setOnItemClickListener（新OnItemClickListener（）{
        @覆盖
        公共无效onItemClick（适配器视图＆LT;＆GT;母公司，观景，INT位置，
                长ID）{
            字符串的packageName = results.get（位置）;
            意向意图=新意图（android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS）;
            intent.setFlags（Intent.FLAG_ACTIVITY_NEW_TASK）;
            intent.setData（Uri.parse（套餐+的packageName））;
            startActivity（意向）;
        }
    }）;
 

my code displays installed apps having specific permissions in a listview. i want to open the settings where you can uninstall apps on each list item (app) .How do i do that?

here is the snippet for opening app's settings

packageName = "com.wagtailapp";
    try {
        // Open the specific App Info page:
        Intent intent = new Intent(
                android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
        intent.setData(Uri.parse("package:" + packageName));
        startActivity(intent);
    } catch (ActivityNotFoundException e) {
        // e.printStackTrace();
        // Open the generic Apps page:
        Intent intent = new Intent(
                android.provider.Settings.ACTION_MANAGE_APPLICATIONS_SETTINGS);
        startActivity(intent);

here is my activity

public class MainActivity extends Activity {

    ArrayList<String> results = new ArrayList<String>();

     @Override
       protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
          getInstalledApps(this);
          ArrayAdapter adapter = new ArrayAdapter<String>(this, R.layout.activity_listview, results);

          ListView listView = (ListView) findViewById(R.id.mobile_list);
          listView.setAdapter(adapter);
       }

      private ArrayList<String> getInstalledApps(Context context) {
        PackageManager packageManager = context.getPackageManager();
        List<PackageInfo> applist = packageManager.getInstalledPackages(0);
        Iterator<PackageInfo> it = applist.iterator();
        while (it.hasNext()) {
            PackageInfo pk = (PackageInfo) it.next();
            if ((pk.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0) {
                Log.v("system app using internet = ", ""+pk.applicationInfo.loadLabel(packageManager));
                continue;
            }

            if (PackageManager.PERMISSION_GRANTED == packageManager .checkPermission(Manifest.permission.INTERNET, pk.packageName) ||
                    PackageManager.PERMISSION_GRANTED == packageManager .checkPermission(Manifest.permission.READ_EXTERNAL_STORAGE, pk.packageName))
                results.add("" + pk.applicationInfo.loadLabel(packageManager));
        }

        Log.v("app using internet = ", results.toString());

        return results;
    }
}

解决方案

Paste this code inside your onCreate() below listView.setAdapter(adapter);

 listView.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position,
                long id) {
            String packageName = results.get(position);
            Intent intent = new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            intent.setData(Uri.parse("package:" + packageName));
            startActivity(intent);
        }
    });
