定义layout_weight为水平？

Question

I am trying to use android:layout_weight but I can't. I use linearlayout and I use vertical orientation because when I use horizontal every element goes on one line.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:weightSum="10"
     >

When I use vertical android assign weight az vertically.

<EditText
        android:id="@+id/etFirstNumber"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="5"
         />

     <EditText
        android:id="@+id/etSecondNumber"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="5"
         />

Look at this (sorry I haven't enough reputation).

The thing that I want to do is putting two edittext elements on same line. How to do that?

        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="5"/>

     ...
     ..
     </Button>
</LinearLayout>

Try putting the EditText(s) in a new LinearLayout to manage the hierarchy better. Also set the width as 0dp so the layout_weight works correctly.

 <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:weightSum="10"
    android:orientation="horizontal">

 <EditText
    android:id="@+id/etFirstNumber"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="5" />

 <EditText
    android:id="@+id/etSecondNumber"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="5"/>

 </LinearLayout>

for Horizontal Layout use android:orientation="horizontal" in you LinearLayout with :

    android:layout_width="0dp"
    android:layout_weight="1"

for Vertical Layout use android:orientation="vertical" in you LinearLayout with :

    android:layout_height="0dp"
    android:layout_weight="1"
