错误:

android.security.KeyChainException: java.lang.IllegalStateException: uid 10111 doesn't have permission to access the requested alias

码:

new Thread(new Runnable() {

        public void run() {
            try {
                X509Certificate[] myCertificates=KeyChain.getCertificateChain(MainActivity.this, "ServerCertificate");
                if(myCertificates!=null)
                {
                    System.out.println("myCertificates size "+myCertificates.length);

                    for(int i=0;i<myCertificates.length;i++)
                    {
                        System.out.println("myCertificates i= "+i+"    "+myCertificates[i]);
                    }
                }
            } catch (KeyChainException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }).start();

我创建了一个简单的ListView包含checkedTextView.

我想在用户点击listView行时添加一个监听器,

1 - 将检查textView.

2 - 如果列表中有另一个文本视图已选中,则取消选中.

这是我写的代码到现在为止:

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        ArrayList<String> mStrings = new ArrayList<String>();
        for(int i=0; i<30; i++) {
            mStrings.add("Item " + i);
        }

        setListAdapter( new MultiAdapter(this, mStrings));

        /* Configure ListView */
        ListView lv = getListView();
        lv.setOnItemClickListener(new ItemClick());
    }

    class ItemClick implements OnItemClickListener {
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

        }
    }

    private class MultiAdapter extends ArrayAdapter<String> {

        private ArrayList<String> mItems;

        public MultiAdapter(Context context, ArrayList<String> mStrings) {
            super(context, …

我想转换一个串号开头00,以+如0046760963101来+46760963101.有没有解决办法通过正则表达式来处理它？

如果不是你推荐什么解决方案？

附录:

如果它以000或更多开头,我不想用+号替换.

所以我想测试2 1NSString,看看它们在我输入时是否相同:

NSString *theOriginalString = [NSString stringWithFormat:@"Superman"];

NSString *theTypedString = [textView string];

我想在输入时查看是否TypedString有错,如果有人输入了错误的答案,则会弹出警告.

先感谢您.

我有以下ViewModel类：

class PersonViewModel(
        context: Application,
        private val dataSource: MoviesRemoteDataSource)
    : AndroidViewModel(context) {

    internal val compositeDisposable = CompositeDisposable()
    val person: ObservableField<Person>()
    private val isVisible = ObservableBoolean(false)

    fun showPerson(personId: String) {
        val personSubscription = dataSource.getPerson(personId)
                .subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe({ person ->
                    isVisible.set(true)
                    this.person.set(person)
                }
                ) { throwable -> Timber.e(throwable) }

        compositeDisposable.add(personSubscription)
    }
}

这是Person类：

class Person(
        @SerializedName("birthday")
        var birthDay: String?,
        @SerializedName("deathday")
        var deathDay: String?,
        var id: Int,
        @SerializedName("also_known_as")
        var alsoKnowAs: List<String>,
        var biography: String,
        @SerializedName("place_of_birth")
        var placeOfBirth: String?)

它在ViewModel的这一行显示错误：

val person: ObservableField<Person>()

它说 …

我已经开始学习Jetpack compose。我正在从 Google 检查此示例：https://github.com/android/compose-samples/blob/main/Crane/app/src/main/java/androidx/compose/samples/crane/home/MainActivity.kt

如您所见，MainScreen 可组合函数是文件中的方法，而不是 MainActivity 类中的内部函数。MainScreen 尚未在其他任何地方使用过。那么为什么不在Activity中将其定义为私有内部函数呢？

您能向我描述一下原因吗？
