标签： java android

我制作了一个应用程序，它在虚拟设备和真实设备中运行良好，但今天我的应用程序正在抛出异常，也许这里有一些旧错误，但我找不到自己的答案。所以，请告诉我如何解决它，非常感谢

这是我的logcat

    public static String getTitleTextFromView(){

}

我认为问题与listview有关，因为当listview上没有数据时，它很好，但是对于数据，它会抛出错误。

2 个答案:

答案 0 :(得分：1)

android:id="@+id/list"

使用它，欢迎您

PS：改变

ListView myList = (ListView) findViewById(android.R.id.list);

有：

ListView myList = (ListView) findViewById(R.id.list);

答案 1 :(得分：1)

我相信你目前的问题是

<TextView
       android:id="@+id/programtitle"
       ...
       android:drawableLeft="@+id/programtime" />  // HERE

您正在引用其他TextView，但您应该引用Drawable。我的猜测是你想把它放在另一个TextView的左边？

如果是这种情况，LinearLayout默认情况下会从左到右排列它们，因此您只需将它们按照您希望它们出现的顺序排列即可。此外，不是问题，但由于默认情况下它们是从左到右，所以不需要

android:orientation="horizontal"

当您ListView中没有任何项目时，它没有显示，因为布局永远不会膨胀，因此错误永远不会被捕获。
