下面这是我的code，但我得到默认的Andr​​oid启动器图标的所有正在运行的应用程序：

  PackageManager PM = getPackageManager（）;

            ActivityManager AM1 =（ActivityManager）getSystemService（Context.ACTIVITY_SERVICE）;

            名单＆LT; RunningTaskInfo＆GT;流程= am1.getRunningTasks（Integer.MAX_VALUE的）;

                如果（进程！= NULL）{
                    对于（INT K = 0; K＆LT; processes.size（）; k ++）{
                        //字符串PKGNAME = app.getPackageName（）;
                        字符串的packageName = processes.get（K）.topActivity
                                .getPackageName（）;
                        可绘制ICO = NULL;
                        尝试
                        {
                         字符串PNAME =（字符串）pm.getApplicationLabel（PM
                                .getApplicationInfo（的packageName，
                                        PackageManager.GET_META_DATA））;

                            ICO = pm.getApplicationIcon（PNAME）;

                        }
                        赶上（的NameNotFoundException E）
                        {
                            Log.e（错误，无法找到图标包'
                                    +的packageName +'：+ e.getMessage（））;
                        }
                        icons.put（processes.get（K）.topActivity.getPackageName（），ICO）;
                    }
 

解决方案

只是替换这行

  ICO = pm.getApplicationIcon（PNAME）;
 

本

  ICO = getApplicationInfo（）loadIcon（getPackageManager（））。
 

EDITED 满code：

 公共无效getAllICONS（）{

    PackageManager下午= getPackageManager（）;

    ActivityManager AM1 =（ActivityManager）getSystemService（Context.ACTIVITY_SERVICE）;

    名单＆LT; RunningTaskInfo＆GT;流程= AM1
            .getRunningTasks（Integer.MAX_VALUE的）;

    如果（进程！= NULL）{
        为（中间体K = 0; K＆小于5; k ++）{
            //字符串PKGNAME = app.getPackageName（）;
            字符串的packageName = processes.get（K）.topActivity
                    .getPackageName（）;
            Log.e（的packageName  - ＆gt;中，+的packageName）;
            可绘制ICO = NULL;
            尝试 {
                字符串PNAME =（字符串）pm.getApplicationLabel（PM
                        .getApplicationInfo（的packageName，
                                PackageManager.GET_META_DATA））;
                name.add（+ PNAME）;
                ApplicationInfo A = pm.getApplicationInfo（的packageName，
                        PackageManager.GET_META_DATA）;
                ICO = getPackageManager（）。getApplicationIcon（
                        processes.get（k）的.topActivity.getPackageName（））;
                getPackageManager（）;
                Log.e（ICO  - ＆gt;中，+ ICO）;

            }赶上（的NameNotFoundException E）{
                Log.e（错误，无法找到图标包'
                        +的packageName +'：+ e.getMessage（））;
            }
            // icons.put（processes.get（K）.topActivity.getPackageName（），ICO）;
            icons.add（ICO）;

        }
    }
}
 

以上code是显示你喜欢的图标：

Below here is my code but i am getting default android launcher icon for all running applications:

PackageManager pm = getPackageManager();

            ActivityManager am1 = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);

            List<RunningTaskInfo> processes = am1.getRunningTasks(Integer.MAX_VALUE);

                if (processes != null) {
                    for (int k = 0; k < processes.size(); k++) {
                        // String pkgName = app.getPackageName();
                        String packageName = processes.get(k).topActivity
                                .getPackageName();
                        Drawable ico = null;
                        try
                        {
                         String pName = (String) pm.getApplicationLabel(pm
                                .getApplicationInfo(packageName,
                                        PackageManager.GET_META_DATA));

                            ico = pm.getApplicationIcon(pName);

                        } 
                        catch (NameNotFoundException e) 
                        {
                            Log.e("ERROR", "Unable to find icon for package '"
                                    + packageName + "': " + e.getMessage());
                        }
                        icons.put(processes.get(k).topActivity.getPackageName(),ico);
                    }

just replace this line

ico = pm.getApplicationIcon(pName);

to this

ico = getApplicationInfo().loadIcon(getPackageManager()); 

EDITED full code :

public void getAllICONS() {

    PackageManager pm = getPackageManager();

    ActivityManager am1 = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);

    List<RunningTaskInfo> processes = am1
            .getRunningTasks(Integer.MAX_VALUE);

    if (processes != null) {
        for (int k = 0; k < 5; k++) {
            // String pkgName = app.getPackageName();
            String packageName = processes.get(k).topActivity
                    .getPackageName();
            Log.e("packageName-->", "" + packageName);
            Drawable ico = null;
            try {
                String pName = (String) pm.getApplicationLabel(pm
                        .getApplicationInfo(packageName,
                                PackageManager.GET_META_DATA));
                name.add("" + pName);
                ApplicationInfo a = pm.getApplicationInfo(packageName,
                        PackageManager.GET_META_DATA);
                ico = getPackageManager().getApplicationIcon(
                        processes.get(k).topActivity.getPackageName());
                getPackageManager();
                Log.e("ico-->", "" + ico);

            } catch (NameNotFoundException e) {
                Log.e("ERROR", "Unable to find icon for package '"
                        + packageName + "': " + e.getMessage());
            }
            // icons.put(processes.get(k).topActivity.getPackageName(),ico);
            icons.add(ico);

        }
    }
}

above code is show you icons like:
