布局XML对此有何影响？

Question

这可能是一个非常愚蠢的问题，但我对这些列表项的布局XML有几个问题

我知道有三个文本视图，但他们是如何在最后一行留下缩进的？另外，它们是如何导致第二个textview在一定数量的行之后换行的？

如果有人可以发布样本XML，那也很棒。

Answer 1

最后一个TextView要么布局对齐到右边（layout_gravity），要么它匹配父宽度并且它的重力（不是布局一个，但它自己的）到右边。

要椭圆化第二个TextView，给它一个有效的高度，然后将ellipsize属性设置为end。

Answer 2

使用以下xml，最后一个textview在右边。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <TextView
        android:maxLines="2" 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
    />
    <TextView 
        android:maxLines="5"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
    />
    <TextView 
        android:layout_gravity="right"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
    />


</LinearLayout>

Answer 3

配方是ScrollView + TextView + LinearLayout + gravity。 对于相同的外观，请检查：

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


<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical">


<ScrollView 
    android:id="@+id/sv"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"> 
<LinearLayout 
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <TextView  
    android:layout_width="fill_parent" 
    android:textSize="24dip"
    android:layout_height="wrap_content" 
    android:text="Morning"
    />
    <TextView  
    android:layout_width="fill_parent" 
    android:textSize="14dip"
    android:layout_height="wrap_content" 
    android:text="Layout container for a view hierarchy that can be scrolled by the user, allowing it to be larger than the physical display. A ScrollView is a FrameLayout, meaning you should place one child in it containing the entire contents to scroll; this child may itself be a layout manager with a complex hierarchy of objects. A child that is often used is a LinearLayout in a vertical orientation, presenting a vertical array of top-level items that the user can scroll through. "
    />
    <TextView  
    android:layout_width="fill_parent" 
    android:textSize="12dip"
    android:layout_height="wrap_content" 
    android:text="Morning"
    android:gravity="right"
    />
        <TextView  
    android:layout_width="fill_parent" 
    android:textSize="24dip"
    android:layout_height="wrap_content" 
    android:text="Morning"
    />
    <TextView  
    android:layout_width="fill_parent" 
    android:textSize="14dip"
    android:layout_height="wrap_content" 
    android:text="Layout container for a view hierarchy that can be scrolled by the user, allowing it to be larger than the physical display.

    <TextView  
    android:layout_width="fill_parent" 
    android:textSize="24dip"
    android:layout_height="wrap_content" 
    android:text="Morning"
    />
    <TextView  
    android:layout_width="fill_parent" 
    android:textSize="14dip"
    android:layout_height="wrap_content" 
    android:text="Layout container for a view hierarchy that can be scrolled by the user, allowing it to be larger than the physical display.

</LinearLayout>
</ScrollView>

</LinearLayout>

（您可以用TextView替换ListView）
