我有一个带有一个 URL 的 Web 视图，每当它在 Web 视图中重定向时，我都会使用具有新标题的新 URL 再次加载相同的可组合项，因为重定向发生得如此之快，它发生在实际可组合项完全组成之前，因此它崩溃了java.lang.IllegalStateException：指定的子级已经有父级。您必须首先对子级的父级调用removeView()。我目前正在使用 ram Costa 的 compose 目标库

navigator.value?.navigate(direction = MenuViewDestination,onlyIfResumed = true)

，我之前也使用过 compose 提供的导航，在这两种情况下我都面临着同样的问题，如果我仅使用恢复 true 进行导航，则页面由于某种原因不会自行导航，并且我无法按原样处理异常发生在内部。这里我附加了菜单可组合项中使用的可组合项来加载 URL，

当我按下主页按钮时,应该暂停应用程序,保存所有状态并正常工作.相反,我得到这个错误:

java.lang.RuntimeException:无法暂停活动{be.test.tester/be.test.tester.DataScreen}:java.lang.IllegalStateException:派生类未在android.app.ActivityThread.performPauseActivity中调用super.onSaveInstanceState() (ActivityThread.java:3641)位于android.app.A活动时的android.app.ActivityThread.performPauseActivity(ActivityThread.java:3598),android.app.A活动.事件(ActivityThread.java:3574),android.app.ActivityThread.access $ 2500(ActivityThread.java) :136)在android.app.A.运行时,Android.O.Roper.loop(Looper.java:143)的android.app.Handler.dispatchMessage(Handler.java:99)上的android.app.ActivityThread $ H.handleMessage(ActivityThread.java:2186)在android.app.ActivityThread.main(ActivityThread.java:5068)的java.lang.reflect.Method.invokeNative(Native Method),位于com.android的java.lang.reflect.Method.invoke(Method.java:521) .internal.os.ZygoteInit $ MethodAndArgsCaller.run(ZygoteInit.java:858)位于dalvik.system.NativeStart.mai的com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616)n(原生方法)

我的活动在触摸时做出反应:

public class DataScreen extends Activity implements OnGestureListener{   

我从意图中获得了一些额外的东西:

totUsage = Integer.parseInt(getIntent().getStringExtra("extraTotUsage"));
    limit = Integer.parseInt(getIntent().getStringExtra("extraLimit"));
    Bundle bundle = getIntent().getExtras();
    mylist = (ArrayList<HashMap<String, String>>) bundle.get("extraMyList");

自定义视图显示数据(画布).在屏幕上滚动时,数据会在自定义视图(set,get方法)中更改并重绘自身.

我真的没有在这里管理onSaveInstanceState,不知道我是否必须这样做.

我的应用程序是堆栈的顶部,因为:

i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

我不明白这个错误.

我试图将一个位图图像设置为画布使用 setBitMap,当时我得到了一个IllegalStateException.这个画布当前有一些图像,我试图替换它.任何人都知道为什么会这样？

代码片段

editBm = Bitmap.createBitmap(951, 552, Bitmap.Config.ARGB_8888);    
        Canvas mCanvas=new Canvas(editBm);
        eBit=LoadBMPsdcard(filePath); ---->returns a bitmap when the file path to the file is provided
        Log.i("BM size", editBm.getWidth()+"");
        mCanvas.setBitmap(eBit);

我没有得到任何NullPointer错误,并且该方法 LoadBMPsdcard() 运行良好.

请告诉我你的任何想法......

提前致谢

快乐的编码

在Android中创建和填充我的新SQLiteDatabase时,我遇到两个相互矛盾的异常.总之我的代码:

SQLiteOpenHelper扩展类:

public void onCreate(SQLiteDatabase db) {
    db.execSQL(DB_TABLE_CREATE);
    loadLevelData(db); //puts data in the database
    //db.close(); <<< ?
}

在我的activity类中,我实例化了这个类(在onCreate()中),并调用getWritableDatabase():

dbHelper = new DbOpenHelper(getApplicationContext());
database = dbHelper.getWritableDatabase();  

现在如果我db.close()在填充数据库之后没有调用,就像上面那样,我得到了

android.database.sqlite.DatabaseObjectNotClosedException: Application did not close the   cursor or database object that was opened here  

但是,如果我关闭它,我会得到以下异常:

java.lang.IllegalStateException: database not open

在getWritableDatabase()上.

这真让我困惑,所以有人可以帮我解决错误吗？

我正在创建一个网页,使用FacesUtils中的getSessionMap()从上一页获取id.如果页面没有获得id,则应将其重定向到其他页面,在本例中为draft.jsf.这是代码:

if ((FacesUtils.getSessionMap().get("id") == null)) {
    try {
        FacesUtils.getResponse().sendRedirect("draft.jsf");
        return;         
    } catch (Exception e) {
        e.printStackTrace();
}
} else {
    id = Long.valueOf(String.valueOf(FacesUtils.getSessionMap().get("id")));
}

但我总是得到java.lang.IllegalStateException:当id为null时提交,并且页面未被重定向到draft.jsf.我的代码出了什么问题？任何帮助将非常感激.

我想在android中实现autocomplete place google API.为此,我需要创建一个GoogleApiClient对象.我已经使用了以下代码...

private GoogleApiClient mGoogleApiClient;

mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
                .addApi(Drive.API)
                .addScope(Drive.SCOPE_FILE)
                .enableAutoManage(getActivity(), 0 /* clientId */, this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .build();

但是当片段启动时,它会抛出以下异常并且应用程序崩溃了.

java.lang.IllegalStateException:已经管理了ID为0的GoogleApiClient

注意:这是在FRAGMENT中执行的.

https://developer.android.com/reference/android/view/View.DragShadowBuilder#public-constructors

当我使用上面概述的第二个构造函数时-“ View.DragShadowBuilder（）构造一个没有关联的View的阴影生成器对象。”

引发以下异常：java.lang.IllegalStateException：拖动阴影尺寸必须为正

第二行代码对我来说是这样的：

public boolean onLongClick(View view) {
    view.startDragAndDrop(null, new View.DragShadowBuilder(), view, 0); 
    return true;
}

它仅在Android 9 Pie上发生。我已经在以前的Android版本上尝试过了，没有问题。我在Android问题追踪器上创建了一个问题，但也许这里有人知道为什么会发生或如何解决。

同时，我正在创建新的View.DragShadowBuilderView（view），其中view是一个透明的ImageView，现在可以停止崩溃，但是我不确定这是否是最佳解决方案。
