Android：适合每个屏幕的listview的每个项目

我想适合每个屏幕上的每个项目/行。但为了实现这一点，我在dp中为行的xml指定了高度和宽度。因为我指定了高度/宽度，所以每一行并不完全适合屏幕，也不适合所有类型的屏幕分辨率。我将如何做到这一点？有人能给出想法吗

这是xml文件：

提前感谢。

您是否尝试过这两种方法，而不是指定dpi的

    android:layout_height="fill_parent" 
    android:layout_width="fill_parent"

您是否曾与懒洋洋一起工作过

试试这个

有关更多详细信息，请使用线性布局，使用加权和功能，您可以在任何程度上分割scren分辨率。

否。它不起作用。这就是为什么我要为线性布局和文本视图指定宽度/高度？仅为线性布局，它不会产生任何影响。如果我给文本视图，它将反映。我可以使用填充父对象进行线性布局。抱歉，是测试代码…嗯。它在使用listview时不起作用。因此，我现在使用viewpager并将其自定义为垂直：这是我的一排。xml@eager-添加有问题的xml文件，以便每个人第一眼看到。。！！！通过为布局指定固定高度，您可能无法为每个android设备获得所需的输出。为此，请使用fill_parent.：）对listview使用fill\u父项无效！！！！请用xml给出您的listview代码，这样可以给您最好的答案。谢谢您的代码。但我必须指定宽度/高度。所以我现在使用viewpager并将其自定义为垂直。@渴望-我会先给你这个建议…但我想让我先尝试列表@急切-如果您想指定宽度/高度，请在TextView中的lazyadapter_layout.xml中指定@nilayonAndrod-很抱歉回复晚了。我不想指定宽度和高度。但如果我使用布局，我必须指定。我尝试使用LazyAdapterXML。这就是我放弃使用listview的原因！！
