并排查看两个按钮

Question

​

​

我有两个按钮Login和Scan。我希望这些按钮是水平的方式，就像在单行。我打了个平手，布局是水平的。然而，它不起作用。它们应该并排出现。我的代码如下。

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/imagesand"
android:orientation="vertical"
tools:context=".MainActivity" >

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:layout_marginTop="5dp"
    />

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/imagesand"
    android:gravity="center"
    android:orientation="vertical" >

    <LinearLayout
        android:layout_width="207dp"
        android:layout_height="wrap_content"
        android:layout_marginLeft="40dp"
        android:layout_marginRight="40dp"
        android:background="@drawable/loginbg"
        android:gravity="center"
        android:orientation="vertical"
        android:layout_alignParentBottom="true"
        android:paddingLeft="20dp"
        android:paddingRight="20dp" >

        <TextView
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="10dp"
            android:text="User Name"
            android:textAppearance="@android:style/TextAppearance.Medium" />

        <EditText
            android:id="@+id/emailid"
            android:layout_width="156dp"
            android:layout_height="45dp"
            android:layout_marginTop="5dp"
            android:background="@drawable/button"
            android:hint="User Name"
            android:inputType="text"
            android:paddingLeft="10dp"
            android:textAppearance="@android:style/TextAppearance.Medium" />

        <TextView
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="15dp"
            android:text="Password"
            android:textAppearance="@android:style/TextAppearance.Medium" />

        <EditText
            android:id="@+id/password"
            android:layout_width="156dp"
            android:layout_height="45dp"
            android:layout_marginTop="5dp"
            android:background="@drawable/button"
            android:hint="Password"
            android:inputType="textPassword"
            android:paddingLeft="10dp"
            android:textAppearance="@android:style/TextAppearance.Medium" />

        <Button
            android:id="@+id/login"
            android:layout_width="71dp"
            android:layout_height="wrap_content"
            android:layout_marginBottom="10dp"
            android:layout_marginTop="15dp"
            android:layout_weight="1"
            android:background="@drawable/login"

            android:text="Login"
            android:textAppearance="@android:style/TextAppearance.Medium"
            android:textColor="#000000"
            android:typeface="serif" />

        <Button android:id="@+id/scan"
            and 
            android:layout_width="71dp" 
            android:layout_height="wrap_content"
             android:layout_marginBottom="10dp"
              android:layout_marginTop="15dp" 
              android:layout_weight="1" 
              android:background="@drawable/login"
               android:text="scan"/>
    </LinearLayout>

   </LinearLayout>

</LinearLayout>

只需将这两个按钮都放入方向必须为horizontal的LinearLayout中

Answer 2

简单地使用这个..

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

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

    <Button
        android:id="@+id/textView"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_gravity="left|center"
        android:layout_weight="1"
        android:text="Login"
        android:textColor="#000000" />

    <Button
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_gravity="right"
        android:layout_weight="1"
         android:text="Scan"
        android:textColor="#000000" />
</LinearLayout>
</LinearLayout>
