首先感谢万能的google!

PackageManager pm = this.getPackageManager();

Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);

mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);

List appList = pm.queryIntentActivities

(mainIntent, 0);

Collections.sort(appList, new ResolveInfo.DisplayNameComparator

(pm));

for(int i=0; i<>

mainText.setText(mainText.getText() + " " +

"number: " + i + " " +

"Name: " + appList.get(i).loadLabel(pm) + " "

);

}

Intent i = new Intent();

i.setAction(Intent.ACTION_MAIN);

i.addCategory(Intent.CATEGORY_LAUNCHER);

i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |

Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);

i.setComponent(new ComponentName(appList.get

(4).activityInfo.applicationInfo.packageName, appList.get

(4).activityInfo.name));

startActivity(i);
