Question

因此,我有这份“To”文本,是供联系人参考的斜体,还有一个搜索塔,以寻找所有线上的接触。文本概览和纽伦都是好的,但问题在于斜体是小的,希望它占据所有剩余的空间。该法典:

<RelativeLayout  
        android:layout_height="wrap_content"  
        android:layout_width="fill_parent"
        android:paddingTop="10dp">
        <TextView  
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content" 
            android:text="To: "
            android:textColor="#000000"
            android:paddingTop="10dp"
            android:layout_toLeftOf="@+id/editText_recipient"
            android:layout_alignParentLeft="true"
            android:layout_marginLeft="10dp"/> 
        <EditText
            android:id="@+id/editText_recipient"
            android:layout_height="wrap_content"
            android:layout_width="wrap_content"   
            android:hint="Enter Number"  
            android:inputType="number"
            android:textSize="12sp"
            android:layout_toLeftOf="@+id/button_recipient_picker"  
            android:layout_marginLeft="5dp"/>
        <Button  
            android:id="@+id/button_recipient_picker" 
            android:layout_height="wrap_content"   
            android:layout_width="wrap_content"  
            android:text="Browse .."  
            android:layout_alignParentRight="true" 
            android:layout_marginLeft="5dp"
            android:layout_marginRight="5dp"
            android:onClick="doLaunchContactPicker"/>
        </RelativeLayout>

<LinearLayout  
        android:layout_height="wrap_content"  
        android:layout_width="fill_parent"
        android:paddingTop="10dp">
        <TextView  
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content" 
            android:text="To: "
            android:textColor="#000000"
            android:paddingTop="10dp"
            android:layout_marginLeft="10dp"/> 
        <EditText
            android:id="@+id/editText_recipient"
            android:layout_height="wrap_content"
            android:layout_width="wrap_content"   
            android:hint="Enter Number"  
            android:inputType="number"
            android:textSize="12sp"
            android:layout_marginLeft="5dp"
            android:layout_weight="1"
         />
        <Button  
            android:id="@+id/button_recipient_picker" 
            android:layout_height="wrap_content"   
            android:layout_width="wrap_content"  
            android:text="Browse .."  
            android:layout_marginLeft="5dp"
            android:layout_marginRight="5dp"
            android:onClick="doLaunchContactPicker"/>
        </LinearLayout>

使用这种布局,即把你的布局改为线性(横向违约)。并且加上一个排外-对倾斜,它将占用剩余的空间。

Answer 2

For those who need an answer to this and to resolve this post without giving an alternative, the answer is fairly simple. You need to tell every control where to position according to each other and apply to the control which should take available space android:layout_width = "match_parent" even though in a LinearLayout, this would push every other control aligned out of the screen, in a RelativeLayout it works perfectly

<RelativeLayout  
    android:layout_height="wrap_content"  
    android:layout_width="match_parent"
    android:paddingTop="10dp">
    <TextView  
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:text="To: "
        android:textColor="#000000"
        android:paddingTop="10dp"
        android:layout_toLeftOf="@+id/editText_recipient"
        android:layout_alignParentLeft="true"
        android:layout_marginLeft="10dp"/> 
    <EditText
        android:id="@+id/editText_recipient"
        android:layout_height="wrap_content"
        android:layout_width="MATCH_PARENT"
        android:hint="Enter number"  
        android:inputType="number"
        android:textSize="12sp"
        android:layout_toLeftOf="@+id/button_recipient_picker"  
        android:layout_marginLeft="5dp"/>
    <Button  
        android:id="@+id/button_recipient_picker" 
        android:layout_height="wrap_content"   
        android:layout_width="wrap_content"  
        android:text="Browse .."  
        android:layout_alignParentRight="true" 
        android:layout_marginLeft="5dp"
        android:layout_marginRight="5dp"
        android:onClick="doLaunchContactPicker"/>
    </RelativeLayout>
