从 android 3.0 开始,您可能想要一个更大的启动器图标,而您无法按照您描述的方式获得。如果是这样,也许我对以下问题的回答可以帮助您:***.com/questions/4600740/getting-app-icon-in-android/… 【参考方案1】:try
String pkg = "com.app.my";//your package name
Drawable icon = getContext().getPackageManager().getApplicationIcon(pkg);
imageView.setImageDrawable(icon);
catch (PackageManager.NameNotFoundException ne)

不适用于 FB、android P 中的 chrome 等少数应用 导致 outOfMemoryError【参考方案2】:以上答案都不错。
您的问题是:- 获取android中所有已安装应用的图标? 你想要安装应用程序图标列表
这里是帮助您使用应用程序(图标,包名称)获取安装应用程序列表的代码。
**Declare variable in your Activity**
private CustomAppListAdapter customAppListAdapter;
private ArrayList<AppListMain> appListMainArrayList;
private AppListMain appListMain;
只需在 Activity onCreate() 中调用下面的函数 loadApps()
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_app_list);
loadApps();
public void loadApps()
try
packageManager = getPackageManager();
appListMainArrayList = new ArrayList<>();
Intent intent = new Intent(Intent.ACTION_MAIN, null);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
List<ResolveInfo> resolveInfoList = packageManager.queryIntentActivities(intent, 0);
for (ResolveInfo resolveInfo : resolveInfoList)
AppListMain appListMain = new AppListMain();
appListMain.setAppIcon(resolveInfo.activityInfo.loadIcon(packageManager));
appListMain.setAppName(resolveInfo.loadLabel(packageManager).toString());
appListMain.setAppPackage(resolveInfo.activityInfo.packageName);
appListMainArrayList.add(appListMain);
catch (Exception e)
e.printStackTrace();

您可以从我的 Github 存储库下载自定义启动器代码

【参考方案3】:我觉得这是最简单的方法:
private List<ResolveInfo> installedApps()
final Intent main_intent = new Intent(Intent.ACTION_MAIN, null);
main_intent.addCategory(Intent.CATEGORY_LAUNCHER);
return package_manager.queryIntentActivities(main_intent, 0);
现在要获取图标,使用这个:
for(ResolveInfo ri : installedApps())
// to get drawable icon --> ri.loadIcon(package_manager)
【讨论】:
【参考方案4】:试试这个方法:创建一个名为PackageInformation
的类:
public class PackageInformation
private Context mContext;
public PackageInformation(Context context)
mContext = context;
class InfoObject
public String appname = "";
public String pname = "";
public String versionName = "";
public int versionCode = 0;
public Drawable icon;
public void InfoObjectAggregatePrint() //not used yet
Log.v(appname, appname + "\t" + pname + "\t" + versionName + "\t" + versionCode);
private ArrayList < InfoObject > getPackages()
ArrayList < InfoObject > apps = getInstalledApps(false);
final int max = apps.size();
for (int i = 0; i < max; i++)
apps.get(i).prettyPrint();
return apps;
public ArrayList < InfoObject > getInstalledApps(boolean getSysPackages)
ArrayList < InfoObject > res = new ArrayList < InfoObject > ();
List < PackageInfo > packs = mContext.getPackageManager().getInstalledPackages(0);
for (int i = 0; i < packs.size(); i++)
PackageInfo p = packs.get(i);
if ((!getSysPackages) && (p.versionName == null))
continue;
InfoObject newInfo = new InfoObject();
newInfo.appname = p.applicationInfo.loadLabel(mContext.getPackageManager()).toString();
newInfo.pname = p.packageName;
newInfo.versionName = p.versionName;
newInfo.versionCode = p.versionCode;
newInfo.icon = p.applicationInfo.loadIcon(mContext.getPackageManager());
res.add(newInfo);
return res;
把它藏在某个地方,现在要从你的工作活动类中访问信息,请执行以下操作:
PackageInformation androidPackagesInfo = new PackageInformation(this);
ArrayList < InfoObject > appsData = androidPackagesInfo.getInstalledApps(true);
for (InfoObject info: appsData)
Toast.makeText(MainActivity.this, info.appname, 2).show();
Drawable somedrawable = info.icon;

【参考方案5】:下面是获取所有已安装应用程序图标的代码。
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
try
// try getting the properly colored launcher icons
LauncherApps launcher = (LauncherApps) this.getSystemService(LAUNCHER_APPS_SERVICE);
List<LauncherActivityInfo> activityList = launcher.getActivityList(packageName, android.os.Process.myUserHandle());
drawable = activityList.get(0).getBadgedIcon(0);
catch (Exception e)
if (drawable == null)
try
getPackageManager().getApplicationIcon(packageName);
catch (PackageManager.NameNotFoundException e)
e.printStackTrace();
