问题在于componentName 我确定你传递的Controller.java不是DeviceAdminReceiver类型
public class MyDeviceAdminReceiver extends DeviceAdminReceiver {
void showToast(Context context, String msg) {
String status = context.getString(R.string.admin_receiver_status, msg);
Toast.makeText(context, status, Toast.LENGTH_SHORT).show();
}
@Override
public void onEnabled(Context context, Intent intent) {
showToast(context, context.getString(R.string.admin_receiver_status_enabled));
}
@Override
public CharSequence onDisableRequested(Context context, Intent intent) {
return context.getString(R.string.admin_receiver_status_disable_warning);
}
@Override
public void onDisabled(Context context, Intent intent) {
showToast(context, context.getString(R.string.admin_receiver_status_disabled));
}
@Override
public void onPasswordChanged(Context context, Intent intent) {
showToast(context, context.getString(R.string.admin_receiver_status_pw_changed));
}
}
您的ComponentName实例看起来应该更像
new ComponentName(this, MyDeviceAdminReceiver.class);
答案 1 :(得分：0)
还要确保您的AndroidManifest在应用程序标记
中包含以下代码 <receiver android:name=".MyDeviceAdminReceiver"
android:label="@string/sample_device_admin"
android:description="@string/sample_device_admin_description"
android:permission="android.permission.BIND_DEVICE_ADMIN">
<meta-data android:name="android.app.device_admin"
android:resource="@xml/device_admin" />
<intent-filter>
<action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
</intent-filter>
</receiver>
和xml文件夹必须包含一个文件，该文件定义了您要强制执行的所有管理员策略。
