Question

问候！我想收到Android中已建立的附录列表。但该列表仅显示在LogCat中。怎么写，它是在手机上显示的？我使用给定的代码：的的java：

package com.tipfile;     
import java.util.ArrayList;
import android.app.Activity;
import android.os.Bundle;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.content.pm.ResolveInfo;

public class dop extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    PackageManager pm = this.getPackageManager();

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

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

XML：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent">
<TextView 
    android:id="@+id/textSelest"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:textStyle="bold"/>
<ListView 
    android:id="@android:id/list"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:drawSelectorOnTop="false"/>
</LinearLayout>

译者在网上写道。我不懂英语。
