这是它的样子:

但我也希望它看起来像这样:

But I want it too look like this:

这是我的 XML 代码:

And here is my XML code:

</LinearLayout>

更新:在进行 ElDuderino 建议的更改后我的 XML.在此更改之后，两个 TextView 和两个 Spinner 都消失了.他们不在屏幕上.

Update: My XML after making the changes ElDuderino suggested. After this change the two TextView and the two Spinners are gone. They are nowhere on the screen.

推荐答案

原因是这样的:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:orientation="vertical" 
 android:layout_gravity="right"
 **android:gravity="right">**

您将顶部布局设置为将所有内容与右侧对齐，因此设置为 wrap_content 的内部布局不会占用所有可用空间，因此会正确对齐.因此，要么从外部布局中删除 android:gravity，要么将内部布局 layout_width 设置为 match_parent.

You set the top layout to align everything to the right side, so your inner layout, which is set to wrap_content doesn't take all the space available and so gets aligned right. So either remove the android:gravity from the outer layout, OR set your inner layouts layout_width to match_parent.

更新，因为它不起作用:用这个替换你的内部线性布局:(我不得不改变字符串资源，但你会弄清楚)...

Update, as it didn't work : Replace your inner linear layout with this : (I had to change string resources, but you'll figure out)...

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:weightSum="2" >

    <LinearLayout
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:orientation="horizontal" >

        <TextView
            android:id="@+id/textView_from"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="From" />

        <Spinner
            android:id="@+id/spinner1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@android:drawable/btn_dropdown"
            android:spinnerMode="dropdown" />
    </LinearLayout>

    <LinearLayout
