安装的应用程序名单按字母顺序排列 [英] Alphabetize List of Installed Apps

问题描述

我有用户安装的应用程序的列表，并希望它出来已经按字母顺序排列（不是分隔或类似的只按字母顺序排列已经什么）我环顾四周，但我还没有真正找到这样的事（这已全部与分隔）。我觉得这应该是一个简单的事情，但我一直没能弄明白。这里是我的code：

Utilities.java：

 包com.example.awesomefilebuilderwidget;进口公共类公用事业{/ *
 *获取移动所有已安装的应用程序，并返回一个列表
 * @参数C应用程序的语境
 * @返回安装的应用程序列表
 * /
公共静态列表＆LT; ResolveInfo＆GT; getInstalledApplications（上下文C）{
    意向意图=新意图（Intent.ACTION_MAIN）;
    intent.addCategory（Intent.CATEGORY_LAUNCHER）;
    返回c.getPackageManager（）queryIntentActivities（意向，PackageManager.GET_ACTIVITIES）。
}
 

AppInfoAdapter.java：

 包com.example.awesomefilebuilderwidget; 进口公共类AppInfoAdapter扩展BaseAdapter实现过滤的{
私人语境mContext;
私人列表＆LT; ResolveInfo＆GT; mListAppInfo;
私人软件包管理系统mPackManager;
私人列表＆LT; ResolveInfo＆GT; originalListAppInfo;公共AppInfoAdapter（上下文C，列表与LT; ResolveInfo＆GT; listApp，
        软件包管理系统时）{
    mContext = C;
    this.originalListAppInfo = this.mListAppInfo = listApp;
    mPackManager =时;
    Log.d（AppInfoAdapter，顶）;
}@覆盖
公众诠释的getCount（）{
    Log.d（AppInfoAdapter，的getCount（））;
    返回mListAppInfo.size（）;
}@覆盖
公共对象的getItem（INT位置）{
    Log.d（AppInfoAdapter，的getItem）;
    返回mListAppInfo.get（位置）;
}@覆盖
众长getItemId（INT位置）{
    Log.d（AppInfoAdapter，getItemId）;
    返回的位置;
}@覆盖
公共查看getView（最终诠释的立场，观点convertView，父母的ViewGroup）{
    //获取选定的条目
    最后ResolveInfo进入=（ResolveInfo）mListAppInfo.get（位置）;    //参照convertView
    视图V = convertView;    //抬高新的布局，如果空
    如果（V == NULL）{
        LayoutInflater吹气= LayoutInflater.from（mContext）;
        V = inflater.inflate（R.layout.layout_appinfo，NULL）;
        Log.d（AppInfoAdapter，新布局膨胀）;
    }    从布局资源//负荷控制
    ImageView的ivAppIcon =（ImageView的）v.findViewById（R.id.ivIcon）;
    TextView的tvAppName =（TextView中）v.findViewById（R.id.tvName）;
    TextView的tvPkgName =（TextView中）v.findViewById（R.id.tvPack）;
    最后复选框addCheckbox =（复选框）V
            .findViewById（R.id.addCheckbox）;
    Log.d（AppInfoAdapter，从加载布局资源控制）;    //设置要显示的数据
    ivAppIcon.setImageDrawable（entry.loadIcon（mPackManager））;
    tvAppName.setText（entry.activityInfo.loadLabel（mPackManager））;
    tvPkgName.setText（entry.activityInfo.packageName）;}
 

Drag_and_Drop_App：

  //创建新的适配器
    适配器=新AppInfoAdapter（这一点，（名单＆LT; ResolveInfo＆GT;）Utilities.getInstalledApplications（本），getPackageManager（））;
    //加载应用程序列表
   mListAppInfo =（ListView控件）findViewById（R.id.lvApps）;
    //设置适配器列表视图
    mListAppInfo.setAdapter（适配器）;
 

那么，什么将是按字母顺序排列该列表的最佳方式？

更新：

最后的答案：

 公共静态的ArrayList＆LT; ResolveInfo＆GT; getInstalledApplications（上下文C）{
    意向意图=新意图（Intent.ACTION_MAIN）;
    intent.addCategory（Intent.CATEGORY_LAUNCHER）;
    最终软件包管理系统下午= c.getPackageManager（）;
    ArrayList的＆LT; ResolveInfo＆GT; APPLIST =（ArrayList的＆LT; ResolveInfo＆GT;）c.getPackageManager（）queryIntentActivities（意向，PackageManager.GET_ACTIVITIES）。
    Collections.sort（APPLIST，新的比较＆LT; ResolveInfo＆GT;（）{
          公众诠释比较（ResolveInfo EMP1，ResolveInfo EMP2）{
            返回emp1.loadLabel（PM）的ToString（）与compareToIgnoreCase（emp2.​​loadLabel（PM）的ToString（））;
          }
        }）;
    返回APPLIST;
}
 

解决方案

没有测试：

 公共静态的ArrayList＆LT; ResolveInfo＆GT; getInstalledApplications（上下文C）{
    意向意图=新意图（Intent.ACTION_MAIN）;
    intent.addCategory（Intent.CATEGORY_LAUNCHER）;
    ArrayList的＆LT; ResolveInfo＆GT; APPLIST = c.getPackageManager（）queryIntentActivities（意向，PackageManager.GET_ACTIVITIES）。
    Collections.sort（APPLIST，新的比较＆LT; ResolveInfo＆GT;（）{
          公众诠释比较（ResolveInfo EMP1，ResolveInfo EMP2）{
            返回emp1.loadLabel（PM）的ToString（）与compareToIgnoreCase（emp2.​​loadLabel（PM）的ToString（））;
          }
        }）;
    返回APPLIST;
 

}

I have a list of the users installed applications and want it to come out already alphabetized (not on dividers or anything like that just already alphabetized) I looked around but I haven't really found anything like this (it has all been with dividers). I feel like this should be a simple thing to do but I haven't been able to figure it out. Here is my code:

Utilities.java:

package com.example.awesomefilebuilderwidget;

IMPORTS

public class Utilities {

/*
 * Get all installed application on mobile and return a list
 * @param   c   Context of application
 * @return  list of installed applications
 */
public static List<ResolveInfo> getInstalledApplications(Context c) {
    Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.addCategory(Intent.CATEGORY_LAUNCHER);
    return c.getPackageManager().queryIntentActivities(intent, PackageManager.GET_ACTIVITIES);
}

AppInfoAdapter.java:

package com.example.awesomefilebuilderwidget;

 IMPORTS

public class AppInfoAdapter extends BaseAdapter implements Filterable {
private Context mContext;
private List<ResolveInfo> mListAppInfo;
private PackageManager mPackManager;
private List<ResolveInfo> originalListAppInfo;

public AppInfoAdapter(Context c, List<ResolveInfo> listApp,
        PackageManager pm) {
    mContext = c;
    this.originalListAppInfo = this.mListAppInfo = listApp;
    mPackManager = pm;
    Log.d("AppInfoAdapter", "top");
}

@Override
public int getCount() {
    Log.d("AppInfoAdapter", "getCount()");
    return mListAppInfo.size();
}

@Override
public Object getItem(int position) {
    Log.d("AppInfoAdapter", "getItem");
    return mListAppInfo.get(position);
}

@Override
public long getItemId(int position) {
    Log.d("AppInfoAdapter", "getItemId");
    return position;
}

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    // get the selected entry
    final ResolveInfo entry = (ResolveInfo) mListAppInfo.get(position);

    // reference to convertView
    View v = convertView;

    // inflate new layout if null
    if (v == null) {
        LayoutInflater inflater = LayoutInflater.from(mContext);
        v = inflater.inflate(R.layout.layout_appinfo, null);
        Log.d("AppInfoAdapter", "New layout inflated");
    }

    // load controls from layout resources
    ImageView ivAppIcon = (ImageView) v.findViewById(R.id.ivIcon);
    TextView tvAppName = (TextView) v.findViewById(R.id.tvName);
    TextView tvPkgName = (TextView) v.findViewById(R.id.tvPack);
    final CheckBox addCheckbox = (CheckBox) v
            .findViewById(R.id.addCheckbox);
    Log.d("AppInfoAdapter", "Controls from layout Resources Loaded");

    // set data to display
    ivAppIcon.setImageDrawable(entry.loadIcon(mPackManager));
    tvAppName.setText(entry.activityInfo.loadLabel(mPackManager));
    tvPkgName.setText(entry.activityInfo.packageName);

}

Drag_and_Drop_App:

// create new adapter
    adapter = new AppInfoAdapter(this, (List<ResolveInfo>) Utilities.getInstalledApplications(this), getPackageManager());
    // load list application
   mListAppInfo = (ListView)findViewById(R.id.lvApps);
    // set adapter to list view
    mListAppInfo.setAdapter(adapter);

So what would be the best way to alphabetize this list?

UPDATED:

Final answer:

    public static ArrayList<ResolveInfo> getInstalledApplications(Context c) {
    Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.addCategory(Intent.CATEGORY_LAUNCHER);
    final PackageManager pm = c.getPackageManager();
    ArrayList<ResolveInfo> applist = (ArrayList<ResolveInfo>) c.getPackageManager().queryIntentActivities(intent, PackageManager.GET_ACTIVITIES);
    Collections.sort(applist, new Comparator<ResolveInfo>(){
          public int compare(ResolveInfo emp1, ResolveInfo emp2) {
            return emp1.loadLabel(pm).toString().compareToIgnoreCase(emp2.loadLabel(pm).toString());
          }
        });
    return applist;
}

解决方案

Not tested:

public static ArrayList<ResolveInfo> getInstalledApplications(Context c) {
    Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.addCategory(Intent.CATEGORY_LAUNCHER);
    ArrayList<ResolveInfo> applist = c.getPackageManager().queryIntentActivities(intent, PackageManager.GET_ACTIVITIES);
    Collections.sort(applist, new Comparator<ResolveInfo>(){
          public int compare(ResolveInfo emp1, ResolveInfo emp2) {
            return emp1.loadLabel(pm).toString().compareToIgnoreCase(emp2.loadLabel(pm).toString());
          }
        });
    return applist;

}
