布局Android TextView相对于屏幕

Question

我是Android新手，我尝试使用Android在屏幕的特定区域放置文本视图。目前，textview涵盖了整个屏幕。我需要将它限制在特定的中心部分。请参阅下面的屏幕截图（我需要将textview＆＃39帧设为白色方块）：

以下是我目前使用的代码：

    <?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal" 
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:baselineAligned="false"
    android:background="@drawable/help"
    android:gravity="left" 
    android:layout_weight="1">

    <TextView 
        android:layout_width="0dp"
        android:layout_height="wrap_content" 
        android:scrollbars = "vertical"
        android:layout_weight="0.60"
        android:textSize="14sp" 
        android:textStyle="bold" 
        android:id="@+id/text"/>

</LinearLayout>

我尝试了一些我无法解决问题的事情，有人能指出我出错的地方吗？

我似乎应该使用LinearLayout将视图设置为屏幕的某个百分比，但我不确定这是否是正确的方法？

编辑：虽然我已经标记为正确的答案基本上是正确的，但如果您要创建特定的布局，则需要创建不同的布局文件对于每种不同的屏幕尺寸（通常是小，中，大和x大）。这些将放在项目的res文件夹中。

Answer 1

只需给出layout_height，然后使用layout_gravity将textview设置为中心水平或垂直中心....

Answer 2

你想要这个，仪式？

以下是代码： -

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/claim_detail_header_bg" >

    <TextView
        android:id="@+id/text"
        android:text="sgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfdsgfdsgdfsfddjvjkfdnbvkfdnvkjfdvfdvdffdfd"

</RelativeLayout>

Answer 3

尝试使用边距和填充。基本上边距是视图与父视图的偏移量，填充是视图内容的偏移量。

layout_marginTop
layout_marginBottom
layout_marginLeft
layout_marginRight

layout_paddingTop
layout_paddingBottom
layout_paddingLeft
layout_paddingRight
