标签: illegalstateexception

我正在尝试录制音频,但是类的start()方法会MediaRecorder抛出一个IllegalStateException.我使用以下代码:

MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile("/sdcard/");
try {
    recorder.prepare();
} catch (IllegalStateException e) {

// TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
Log.i("Try","Exception");
recorder.start(); 

并获得许可

<uses-permission android:name="android.permission.RECORD_AUDIO" />

在Android中使用SQLiteCursor时,我发现getColumnIndex()的行为区分大小写,例如:

例:

Column Name in DB was: Rules
cursor.getColumnIndex("Rules")  //workes fine
cursor.getColumnIndex("rules")  //throws error, see the error detail

文档没有说明这一点,详情 请看这个.

LogCat说:

java.lang.IllegalStateException:无法从CursorWindow读取第0行col -1.在从中访问数据之前,请确保正确初始化Cursor

我对SQLiteCursor的这种行为感到困惑,有人可以帮助我这是真的还是我做错了什么？如果需要,我可以提供代码.

谢谢.

这是我的PreferenceActivity(我主要活动的内部课程)

public static class TestSettings extends PreferenceActivity implements Preference.OnPreferenceClickListener{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.pref);
        getPreferenceManager().findPreference("key").setOnPreferenceClickListener(this);

    }

这是我的onPreferenceClick:

@Override
public boolean onPreferenceClick(Preference preference) {
    FragmentClass fc = new FragmentClass();
    fc.show(fm, "TAG");
    return false;
}

这是我的FragmentClass(TimePicker对话框):

public class FragmentClass extends DialogFragment implements TimePickerDialog.OnTimeSetListener {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        return new TimePickerDialog(getActivity(), this, 15, 00, false);
    }


    @Override
    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
        Log.i("APP", "hour: "+hourOfDay+", …

我正在开发一个Android应用程序.在这个应用程序中,我在片段中显示MapView.如果我的设备旋转,我尝试使用以下方法之一移动相机:

mapa.animateCamera(cameraUpdate);

要么

mapa.moveCamera(cameraUpdate);

然后我的应用程序崩溃并显示以下错误:

用户单击一个按钮,该按钮会打开一个片段对话框,该对话框会像这样膨胀片段:

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

        View view = getActivity().getLayoutInflater().inflate(
                R.layout.monday_fragment, null);
        builder.setView(view).setTitle("Homework Due Monday")
                .setNegativeButton("Dismiss", null);

        AlertDialog dialog = builder.create();
        dialog.show();

这是指定布局的xml(monday_fragment.xml),其中对要膨胀的片段的引用位于:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity"
    >

    <fragment
        android:id="@+id/monday_fragment"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:name="com.bernard.beaconportal.activities.schedule.daydialogfragments.MondayFragment"
        android:layout_centerHorizontal="true"/>

</RelativeLayout>

片段对话框中的片段然后在其OnCreateView中膨胀自己的布局:

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        swipe = inflater.inflate(R.layout.day_homework_fragment, container,
                false);

        lView = (ListView) swipe.findViewById(R.id.listView1);

        progress = (ProgressBar) swipe.findViewById(R.id.progress);

        lView.setVisibility(View.GONE);

        return swipe;

    }

以下是片段中膨胀的"day_homework_fragment.xml"布局:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    android:layout_gravity="center"

所以我是Spring的新手,我正在努力让文件上传为我的项目工作(我正在使用Spring Tool Suite btw.)并且当我提交表单时,我得到的是:

HTTP状态500 - 无法解析多部分servlet请求; 嵌套异常是java.lang.IllegalStateException:由于未提供多部件配置,因此无法处理部件

登录后我可以进行FB查询.几分钟后(玩游戏)Facebook请求失败异常:

java.lang.IllegalStateException: Cannot execute task: the task is already running

我打电话时失败了

        Request.executeMeRequestAsync(Session.getActiveSession(),
                new Request.GraphUserCallback() {...

        Request.executeGraphPathRequestAsync(Session.getActiveSession(),
                "me/apprequests", new Request.Callback() {...

        Request request = new Request(session, "me/apprequests", null,
                    null, new Request.Callback() { .... } );
        RequestAsyncTask status = request.executeAsync();

登录后立即调用相同的调用,它们可以正常工作.我有一个测试应用程序,它的工作原理.但是在登录后几分钟后的真实应用程序中它无效.

我的应用程序会在许多Android平台(4.1,4.0.4,2.3.6 ......)上报告此问题.但我无法在手机上重现此问题.我已经通过Google搜索了这个问题,但堆栈跟踪似乎与我的不一样.

有人知道问题是怎么回事吗？以及如何预防呢？或者我该如何重现此错误？谢谢.

致乔纳森:

我有两个片段.并且只有一个片段会覆盖onPause回调,代码如下所示.我之后不会覆盖其他回调onPause.我覆盖的另一个回调是onResume回调,代码也如下所示.

有人可以解释这个异常何时发生？

我有一个正在运行的应用程序，但有时，由于我不知道的原因，应用程序会崩溃并显示以下消息：

我无法在任何地方找到有关此异常发生的信息，而且我也不明白如何避免它。

编辑#1：经过一些研究和测试，我发现当我在 BottomNavigation 中的选项卡之间快速切换时会引发此异常（选项卡包含 LazyColumn）
