我想将我的活动(com.myapp.launcher.settings)添加到空的ArrayList中。
ArrayList<ResolveInfo> selectedApps = new ArrayList<ResolveInfo>();
selectedApps.add(/*WHAT GOES IN HERE?*/);
但我不知道如何通过我的活动获得ResolveInfo对象。
我设法制定了一个解决方法,遍历所有应用程序以查找我的活动。但它不是非常有效或实用:
// 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);
}
}

只需将resolveActivity
与明确Intent
一起使用即可。可能是这样的:
Intent intent = new Intent();
intent.setComponent(new ComponentName("com.myapp", "com.myapp.launcher.settings"));
ResolveInfo app = pm.resolveActivity(intent, 0);
selectedApps.add(app);

如果您不仅知道应用程序的packageName
,那么另一个答案是:
Intent intent = new Intent();
intent.setPackage(packageName);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
ResolveInfo result = packageManager.resolveActivity(intent, 0);
