我做了个bug就是说快捷启动里得到所有的应用程序，然后由于某些原因需要移除某个应用条目，我是这样做的：
1.使用这个工具类获取所有应用程序：
public class ApkTool {
static String TAG = "ApkTool";
private Context mContext;
public static List<AppInfo> mLocalInstallApps = null;
public ApkTool(Context mContext) {
this.mContext = mContext;
}
public List<AppInfo> scanLocalInstallAppList(PackageManager packageManager) {
List<AppInfo> myAppInfos = new ArrayList<AppInfo>();
try {
List<PackageInfo> packageInfos = packageManager.getInstalledPackages(0);
for (int i = 0; i < packageInfos.size(); i++) {
PackageInfo packageInfo = packageInfos.get(i);
// 过滤掉系统app
if ((ApplicationInfo.FLAG_SYSTEM & packageInfo.applicationInfo.flags) != 0) {
continue;
}
AppInfo myAppInfo = new AppInfo();
myAppInfo.setAppPackageName(packageInfo.packageName);
if (packageInfo.applicationInfo.loadIcon(packageManager) == null) {
continue;
}
myAppInfo.setAppName(packageInfo.applicationInfo.loadLabel(mContext.getPackageManager()).toString());
myAppInfo.setImage(packageInfo.applicationInfo.loadIcon(packageManager));
myAppInfos.add(myAppInfo);
}
}catch (Exception e){
Log.e(TAG,"===============获取应用包信息失败");
}
return myAppInfos;
}
}2.在activity中的listview里加载所有应用，之后调用adapter里的removeData方法移除某个包名对应的activity，最关键的是removeData方法，在这里我先是将完整的应用列表通过setData方法传给适配器并调用了notifyDataSetChanged进行列表数据刷新，然后调用adapter里自己定义的一个removeData方法进行条目遍历逐个筛选，将满足条件的条目加到另一个list中，最后将这个list返回，再重新把设置给setData，同样adapter的列表也能得到更新，这样适配器得到的也是筛选后的数据
public class ApplicationInfoSelection extends Activity {
Handler mHandler = new Handler();
AppAdapter mAppAdapter;
private List<AppInfo> appInfos;
private ApkTool apkTool;
private String packagename;
private SharedPreferences sharedPreferences;
private Intent intent;
private List<AppInfo> nowList =new ArrayList<>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

apkTool = new ApkTool(ApplicationInfoSelection.this);
ListView mylisiview = (ListView) findViewById(R.id.lv_app_list);
mAppAdapter = new AppAdapter();
mylisiview.setAdapter(mAppAdapter);
if (mylisiview != null) {
mylisiview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
packagename = nowList.get(position).getAppPackageName();
String appName = nowList.get(position).getAppName();

Bundle bundle =new Bundle();
bundle.putString("test1",appName);
intent.putExtras(bundle);

SharedPreferences.Editor edit = sharedPreferences.edit();
// Settings.System.putInt(getContext().getContentResolver(), "is_gou_show",1);

edit.commit();
sendBroadcast(intent);
//1.让左方的打勾图片显示

this.getContentResolver(), "item_click",

//2.记录包名
