我想添加activity（com.myapp.launcher.settings）到空的ArrayList中：ArrayList<ResolveInfo> selectedApps = new ArrayList<ResolveInfo>();
selectedApps.add(/*WHAT GOES IN HERE?*/);但是我不知道怎么獲取ResolveInfo對(duì)象。我試過使用一個(gè)工作環(huán)境，將所有的應(yīng)用循環(huán)一遍需找activity，實(shí)現(xiàn)之后發(fā)現(xiàn)這種方法不是很好用。// Get an array list of all apps
ArrayList<ResolveInfo> allApps = (ArrayList<ResolveInfo>) pm.queryIntentActivities(intent, PackageManager.PERMISSION_GRANTED);
for(final ResolveInfo app : allApps) {
// If it's name is "com.myapp.launcher.settings" add it
if(app.activityInfo.name.equals("com.myapp.launcher.settings")) {
selectedApps.add(app);
}
}

使用resolveActivity配合顯性intent。就可以：
Intent intent = new Intent();
intent.setComponent(new ComponentName("com.myapp", "com.myapp.launcher.settings"));
ResolveInfo app = pm.resolveActivity(intent, 0);
selectedApps.add(app);添加回答
