问题描述

I have the following layout, it works fine and gives me the result. 我有以下布局，它工作正常，并给了我结果。 The result I want is to divide the screen into two parts and place buttons half in each part: 我想要的结果是将屏幕分为两部分，并将按钮各占一半： 

   <RelativeLayout

                        android:layout_height="wrap_content"
                        android:layout_alignBaseline="@+id/textView3"
                        android:layout_alignBottom="@+id/textView3"
                        android:layout_alignParentRight="true"
                        android:layout_marginRight="14dp"
                        android:text="24 October 2014"
                        android:textColor="#696969" />
                </RelativeLayout>
            </LinearLayout>
        </LinearLayout>

        <Button
            android:id="@+id/imageButton1"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:layout_alignParentRight="true"
            android:layout_centerVertical="true"
            android:layout_marginRight="10dp"
            android:background="@drawable/icon_edit"
            android:textColor="#000000" />

        <Button
            android:id="@+id/imageButton2"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:layout_alignTop="@+id/imageButton1"
            android:layout_marginRight="10dp"
            android:layout_toLeftOf="@+id/imageButton1"
            android:background="@drawable/icon_person" />


    </RelativeLayout>

The only problem I have is that I want the android:id="@+id/relative_layout_top to take 1.5 times the space of android:id="@+id/relative_layout_bottom and still keep the buttons half in android:id="@+id/relative_layout_bottom and half in android:id="@+id/relative_layout_bottom . 我唯一的问题是我想要的android:id="@+id/relative_layout_top采取1.5倍的空间android:id="@+id/relative_layout_bottom ，仍然保持按钮半android:id="@+id/relative_layout_bottom和一半在android:id="@+id/relative_layout_bottom 。 Currently both the halves are of the same size. 目前，两半的大小相同。 Any ideas hints or suggestions how to do that? 任何想法提示或建议如何做到这一点？

Your have to set gravity center to you both LinearLayout which place child at center and set weight 2 to top LinearLayout and 1 to bottom LinearLayout and put button in two LinearLayout used FrameLayout. 您必须将两个孩子的重心都设置到LinearLayout上，并将权重2设置在顶部LinearLayout上，将权重2设置在LinearLayout的顶部，将权重1设置在LinearLayout的底部，然后将按钮放在两个LinearLayout使用的FrameLayout中。 

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
