How can one align spinners right to left?

问题

Can anyone tell me what do I do wrong? :( I have 2 Spinners and two TextViews that I want to align right. I have set everything to right but still everything is left aligned.

Here is how it looks like:

But I want it too look like this:

And here is my XML code:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_gravity="right"
android:gravity="right">
    <RadioGroup
        android:id="@+id/radios"
        android:layout_width="fill_parent"

        android:layout_gravity="right"
        android:gravity="center_horizontal"
        android:inputType="text"
        android:onClick="test"
        android:orientation="horizontal"
        android:paddingRight="10dp" >

        <RadioButton
            android:id="@+id/rbtn_sell"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="10dp"
            android:button="@null"
            android:drawablePadding="3dp"
            android:drawableRight="@android:drawable/btn_radio"
            android:text="@string/label_sell_unicode"
            android:textSize="12sp" />

        <RadioButton

            android:layout_height="wrap_content"
            android:button="@null"
            android:drawablePadding="3dp"
            android:drawableRight="@android:drawable/btn_radio"
            android:text="@string/label_rent_unicode"

    android:layout_gravity="center"
    android:gravity="right"
    android:orientation="horizontal"
    >

    <TextView
        android:id="@+id/textView_from"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/label_from" 
        />
    <Spinner
        android:id="@+id/spinner1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@android:drawable/btn_dropdown"
        android:gravity="right"
        android:layout_gravity="right"
        android:spinnerMode="dropdown" />
    <TextView
        android:id="@+id/textView_to"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/label_to" 
        />
    <Spinner
        android:id="@+id/spinner2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@android:drawable/btn_dropdown"
        android:gravity="right"
        android:layout_gravity="right"
        android:spinnerMode="dropdown" />



</LinearLayout>

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.

回答1:

You made a mistake while adding the drawable on the radiobutton..Try this and lemme know

android:drawableLeft="@android:drawable/btn_radio"

回答2:

Use

   android:layout_toRightOf="@id/textView_from"
   android:layout_toRightOf="@id/textView_to"

this may help you

回答3:

The reason is this :

<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">**

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.

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

        <TextView
            android:id="@+id/textView_to"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="To" />

        <Spinner
            android:id="@+id/spinner2"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@android:drawable/btn_dropdown"
            android:spinnerMode="dropdown" />
    </LinearLayout>
</LinearLayout>
