我正在编写一个像任务管理器这样的应用程序。我想知道如何将用户安装的Android应用程序显示到列表视图中，请大家帮帮我

我刚刚做了一些这样的功能来管理Android中的应用程序，代码还可以，但我想添加更多功能

public void onClick(View v) {
    // TODO Auto-generated method stub
    switch (v.getId()) {
    case R.id.appinfo:
        final ActivityManager actvityManager = (ActivityManager) this.getSystemService( ACTIVITY_SERVICE );

           List<RunningAppProcessInfo> procInfos = actvityManager.getRunningAppProcesses();


            for(int i = 0; i < procInfos.size(); i++)

            {

                    tv.setText(tv.getText().toString()+procInfos.get(i).processName+

                                " " + String.valueOf(procInfos.get(i).processName.length())+"\n");

                    if(procInfos.get(i).processName.equals("com.android.camera")) {

                        Toast.makeText(getApplicationContext(), "Camera App is running", Toast.LENGTH_LONG).show();

                    }
                    else{
                        Toast.makeText(getApplicationContext(), "Camera App is not running", Toast.LENGTH_LONG).show();
                    }

            }

        break;

    case R.id.taskinfo:
         final   ActivityManager activityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
         final List<RunningTaskInfo> recentTasks = activityManager.getRunningTasks(Integer.MAX_VALUE);

          for (int i = 0; i < recentTasks.size(); i++) 
            {
               tv.setText("Executed app"+ "Application executed : " +recentTasks.get(i).baseActivity.toShortString()+ "\t\t ID: "+recentTasks.get(i).id+"");         
            }

          break;

    case R.id.serviceinfo:
        final String APP_TAG = "tag";

        ActivityManager activityManager1 = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
        List<ActivityManager.RunningServiceInfo>runningServices = activityManager1.getRunningServices(50);

        for (int i = 0;i < runningServices.size();i++){

            ActivityManager.RunningServiceInfo runningServiceInfo = runningServices.get(i);

            tv.setText(APP_TAG + "Process " + runningServiceInfo.process + " with component " + runningServiceInfo.service.getClassName());

        }

您可以使用 packageManager 来执行此操作，

 final PackageManager pm = getPackageManager();
//get a list of installed apps.
        List<ApplicationInfo> packages = pm
                .getInstalledApplications(PackageManager.GET_META_DATA);

        for (ApplicationInfo packageInfo : packages) {

            Log.d(TAG, "Installed package :" + packageInfo.packageName);
            Log.d(TAG,
                    "Launch Activity :"
                            + pm.getLaunchIntentForPackage(packageInfo.packageName)); 

             // put application name to an Array, then set listviews adapter with this array
        } 
    }
