与编辑文本输入类型相关的问题

时间:2013-12-20 05:07:18

标签: android

我有一个编辑文本,输入类型为数字。但是在完成任务之后,如果我再次单击编辑文本,则输入类型将更改为文本。

大约一秒钟,它会将输入类型显示为数字,很快就会自动将编辑文本的输入类型更改为文本。即使我点击按键,编辑文本也不会显示任何内容。

我检查了logcat,我得到了这个:

12-20 00:03:09.747: I/Choreographer(5638): Skipped 308 frames!  The application may be doing too much work on its main thread.
12-19 23:57:39.917: W/IInputConnectionWrapper(5638): getTextBeforeCursor on inactive InputConnection
12-20 00:02:45.917: I/InputAttributes(412): InputType.TYPE_NULL is specified

我查看此链接:getExtractedText on inactive InputConnection warning on android

但无法找到解决方案。如果有人可以帮我解决这个问题,将会很有帮助。

这是我的自定义单元格xml(此编辑文本位于列表视图中):

单击mExpiryDate后出现问题。在mExpiryDate的click事件中,使一个处于可见状态的布局变为可见状态。

尝试在xml中使用它。它可能会帮助您,通过禁用数字以外的按钮以及是否要添加更多按钮。

android:digits="0123456789"

我认为你的列表视图状态不是滚动管理的。

    mName.setTypeface(sTfFont);
    mAddress.setTypeface(sTfFont);
    mPolicyNum.setTypeface(sTfFont);
    mNaic.setTypeface(sTfFont);
    mExpiryDate.setTypeface(sTfFont);

您是否通过将其放入if(null==convertView)块进行检查,您应该通过仅在该块内初始化这些相同的字段来进行检查。

    mName=holder.getName();
    mAddress=holder.getAddress();
    mPolicyNum=holder.getPolicyNum();
    mNaic=holder.getNaic();
    mExpiryDate=holder.getExpiryDate();
    mImgCameraImage=holder.getImgCameraImage();

**注意:改变解决方案:我在动态列表视图中遇到了类似的问题,但是我在每个列表项中都有一个微调器,我做的是,我删除了持有者逻辑并将字段与ArrayList值紧密绑定,虽然它对我有用滚动速度稍慢。

跳过308帧!应用程序可能在其主线程上做了太多工作。

您的错误表明您在应用程序的主UI线程上执行了一些耗时的任务,这需要很长时间并且会阻止UI。

尝试使用以下策略以提高应用效果:

  • 如果可能,请使用多线程编程。即使您的智能手机有一个核心(线程可以在不同的核心运行,如果处理器有两个或更多),性能优势也是巨大的。使您的应用程序逻辑与UI分离是很有用的。使用 Java线程 AsyncTask IntentService Check this
  • 阅读并遵循Android开发网站的misc性能提示。 Check here

另请查看Thread

这解决了这个问题:

android:descendantFocusability="afterDescendants"

我将上面的代码添加到xml中的listview中,它解决了这个问题。
