Answer 1

Use a Horizontal LinearLayout and android:layout_weight property to each child.

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

    <View
        android:id="@+id/left"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1" >
    </View>

    <TextView
        android:id="@+id/text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="0.5"
        android:text="Large Text"
        android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>

If you want to use dimensions files(eg to set text_size ), enter the values in dimens.xml in the appropriate folder.

res/values/dimens.xml
res/values-small/dimens.xml
res/values-normal/dimens.xml
res/values-large/dimens.xml
res/values-xlarge/dimens.xml

您也可以简单地尝试以“ px”而不是“ dp”定义尺寸。但是，分配权重始终是一个更好的解决方案。
