对不起，编码员，如果我的帖子与另一个有关隐藏图标启动器的问题类似。我有一个最终项目要制作一个可以隐藏另一个应用程序启动器图标的应用程序。
首先，我得到了如下代码：
Manifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.qp.dev.parentalcontrol">
<uses-feature
android:name="android.hardware.touchscreen"
android:required="false" />
<uses-permission android:name="android.permission.CHANGE_COMPONENT_ENABLED_STATE"
tools:ignore="ProtectedPermissions"
android:protectionLevel="signature"/>
<uses-sdk
android:minSdkVersion="27"
android:targetSdkVersion="27" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity
android:name=".MainActivity"
android:label="@string/app_name"
android:theme="@style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

.java和隐藏其他应用程序图标启动器的所有者 AppListAdapter.java
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
if (convertView == null) {

holder.apkName = (TextView) convertView.findViewById( R.id.appname );

}
final PackageInfo packageInfo = (PackageInfo) getItem( position );

appIcon.setBounds( 0, 0, 80, 80 );

} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
Toast.makeText( context, "Nama Package: " + namaPackage

editor.putInt("status", 1);
editor.apply();

editor.putInt("status", 0);
editor.apply();
}
}
} );
return convertView;
}
我要隐藏另一个应用启动器图标（设置图标的可见性）。我尝试了代码
PackageManager.COMPONENT_ENABLED_STATE_DISABLED
禁用/隐藏应用程序和
PackageManager.COMPONENT_ENABLED_STATE_ENABLED
以启用/显示图标应用程序。
这是应用程序列表的显示：
enter image description here
当我单击复选框隐藏器时有2种不同的错误
1.当我检查system-app时，出现此错误：
enter image description here
at java.util.Objects.requireNonNull（Objects.java:203）
at com.qp.dev.parentalcontrol.adapter.AppAdapter $ 2.onClick（AppAdapter.java:208）
2.当我检查非系统应用程序时，出现此错误：
enter image description here
android.os.Parcel.readException上的（Parcel.java:2004）
at android.os.Parcel.readException（Parcel.java:1950）
在android.content.pm.IPackageManager $ Stub $ Proxy.setComponentEnabledSetting（IPackageManager.java:4732）
在android.app.ApplicationPackageManager.setComponentEnabledSetting（ApplicationPackageManager.java:2276）
at com.qp.dev.parentalcontrol.adapter.AppAdapter $ 2.onClick（AppAdapter.java:221）
我打算通过制作此家长控制应用来完成我的最后一个项目，以取得学士学位。我希望有一种解决该程序的方法，因为我尝试了一个类似Nova Launcher的应用程序，它可以隐藏另一个天堂之类的应用程序。 谢谢您的关注。
