我收到了以下错误.那么如何解锁我的数据库呢？

public class AircraftFragmentTab extends Fragment{
  private String ac;

  public AircraftFragmentTab(String AC){
      ac = AC;

  }
     @Override
     public View onCreateView(LayoutInflater inflater, ViewGroup container,
     Bundle savedInstanceState)
     {
         View aircraftView = inflater.inflate(R.layout.acdetails, container, false);

         ??? getWindow().setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
          WebView wv = (WebView) aircraftView.findViewById(R.id.webac);
          wv.getSettings().setJavaScriptEnabled(true);
          wv.loadUrl("http://ABCD/ACInfo.aspx?AC=" + ac);

         return aircraftView;
     }

}

我正在使用webView,类从Fragment扩展.我怎么在这里使用getWindow()？

我已将ActionBar选项卡添加到我的应用程序中.该下划线的默认颜色为浅蓝色.如何更改所选标签的颜色或样式？

我有一个运行后台服务来获取数据.我检查新数据并发送状态栏通知.发送通知是服务的一部分.当用户看到该通知时,他登录到应用程序并接受它.那个时候我想从状态栏中删除它.我能这样做吗？

我正在使用html5/javascript/jQuery/css进行移动应用程序开发.我在应用程序中有多个textareas.当我点击它输入时,键盘弹出(android选项卡).但是textarea仍然保留在该页面上的位置.键盘弹出时如何滚动页面.

我在SQLite数据库上使用execSQL.sql INSERT strnig是

INSERT INTO Tasks 
(_id, Aircraft, Station, Discrepancy,DateCreated, CreatedBy, Status, DateClosed, ClosedBy, ArrivalFlightID, RecordChangedByUI)  
 VALUES 
('271104','   ','ORD','Critical Flight (0496/28)','9/4/2011 6:57:00 PM','SYSTEM','NEW','','null','0','N')

表是

"create table Tasks 
(_id integer primary key, "
+ "Aircraft text null, Station text null, Discrepancy text null, DateCreated text null, CreatedBy text null, Status text null, DateClosed text, ClosedBy text null, ArrivalFlightID text null, RecordChangedByUI text null);";

它抛出异常"Empty bindArgs"

谁能告诉我哪里出错了？

我有一个典型的登录屏幕(表格布局).我想做的是围绕这些控件绘制一个矩形并在其中放置渐变.我如何在xml中执行此操作？

我该怎么用

requestLocationUpdates(long minTime, float minDistance, Criteria criteria,
                                                           PendingIntent intent) 

在BroadcastReciver中,我可以继续获取GPS坐标.

我是否必须为LocationListener创建一个单独的类？

我的项目的目标是当我收到BOOT_COMPLETED开始定期获得GPS拉特和长期时.

我试过的代码是:

public class MobileViaNetReceiver extends BroadcastReceiver {

    LocationManager locmgr = null;
    String android_id;
    DbAdapter_GPS db;

    @Override
    public void onReceive(Context context, Intent intent) {
        if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
            startGPS(context);
        } else {
            Log.i("MobileViaNetReceiver", "Received unexpected intent "
                + intent.toString());
        }
    }

    public void startGPS(Context context) {
        Toast.makeText(context, "Waiting for location...", Toast.LENGTH_SHORT)
                .show();
        db = new DbAdapter_GPS(context);
        db.open();
        android_id = Secure.getString(context.getContentResolver(),
                Secure.ANDROID_ID);
        Log.i("MobileViaNetReceiver", "Android id is _ _ _ …

我正在使用Handlebars来显示评论.

{{#each COMMENTS}}
     <div class="heightfix">
          <div class="commentIcon"></div>&nbsp;&nbsp;
             <label id="commentDate1" class="bold">{{COMMENTON}}</label>:&nbsp;
             <label id="commentCreator1" class="bold">{{COMMENTBY_FIRSTNAME}} {{COMMENTBY_LASTNAME}}</label>&nbsp;&nbsp;
             <label class="commentContent" id="commenttext_{{ID}}">{{COMMENTTEXT}}</label>
     </div>                                  
{{/each}}   

在那些评论中,我有INDEX.我想根据他们的索引显示评论.评论0评论1评论2评论3 .....

如何使用自定义功能实现此目的？谢谢

我有一个ListView.点击列表项我开始了Activity.现在我添加了一个Buttonon ListView和onclick一个按钮,我想开始另一个活动.添加按钮后,我可以单击按钮并启动一个活动,但现在我无法单击列表项.listview的项目发生了什么？
