OnItemClickListener传递选择的方法的应用程序包名称...帮助 [英] OnItemClickListener that passes the Package Name of the app selected to a method... Help

问题描述

更新：现在找包名称，而不是PID

UPDATE: Now looking for Package Name as opposed to PID

我有diplays设备上的所有安装的应用程序的列表视图的应用程序。我想创建一个选择传递给方法的应用程序软件包名OnItemClickListener。

I have an app that diplays a listview of all the installed apps on the device. I want to create an OnItemClickListener that passes the Package Name of the app selected to a method.

下面是我的code：

public class Main extends ListActivity {

    private static final int ACTIVITY_CREATE=0;
    public static final int Menu1 = Menu.FIRST;


    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        final PackageManager pm = this.getPackageManager();

        Intent intent = new Intent(Intent.ACTION_MAIN, null);
        intent.addCategory(Intent.CATEGORY_LAUNCHER);

        final ArrayList<ResolveInfo> list =
                (ArrayList<ResolveInfo>) pm.queryIntentActivities(intent, 
                        PackageManager.PERMISSION_GRANTED);
        for (ResolveInfo rInfo : list)
        {
            Log.i("Installed Applications " + rInfo.activityInfo.
                    applicationInfo.loadLabel(pm).toString(), null);
        }

        final ArrayAdapter<ResolveInfo> adapter = 
            new ArrayAdapter<ResolveInfo>(this, R.layout.list_item, list)
            {
            @Override
            public View getView(int position, View convertView, ViewGroup parent)
            {
                if (convertView == null)
                    convertView = LayoutInflater.from(parent.getContext()).
                        inflate(R.layout.list_item, parent, false);

                final String text = list.get(position).activityInfo.
                    applicationInfo.loadLabel(pm).toString();
                ((TextView)convertView.findViewById(R.id.text)).setText(text);

                final Drawable drawable = list.get(position).activityInfo.applicationInfo.loadIcon(pm);
                ((ImageView)convertView.findViewById(R.id.image)).setImageDrawable(drawable);

                return convertView;
            }

            };
        setListAdapter(adapter);

        ListView lv = getListView();
        lv.setTextFilterEnabled(true);
        lv.setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {

                // On Item Click Activity

                // This is where I would like to pass the package name to a method
            }
          });
    }

任何帮助将大大AP preciated！

Any help would be greatly appreciated!

推荐答案

您可以检索的 activityInfo 成员包名的 ResolveInfo 实例，其项目您刚刚点击：

You can retrieve the package name for the activityInfo member of the ResolveInfo instance whose item you just clicked on:

lv.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id)
    {
        final String packageName = list.get(position).activityInfo.packageName;
        Log.i("PACKAGE", packageName);
        //TODO: Pass this packageName to a method
    }
});
