我想要一个与此相似的布局：

四方形按钮在屏幕上 - 每个那些使用一半/屏幕高度屏幕（取smaler）的。独立的屏幕尺寸/分辨率。

我已经尝试过使用来实现这一的LinearLayout 但按键都结束了使用正确的宽度，但仍然有背景的高度（非方形更多）。

 ＆LT; LinearLayout中的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android
机器人：方向=垂直机器人：layout_width =FILL_PARENT
机器人：layout_height =FILL_PARENT＆GT;
＆LT; LinearLayout中的android：layout_width =FILL_PARENT
    机器人：layout_height =WRAP_CONTENT＆GT;
    ＆LT;按钮机器人：layout_height =WRAP_CONTENT的风格=@风格/ CKMainButton
        机器人：layout_width =FILL_PARENT机器人：文本=@字符串/景点
        机器人：ID =@ + ID / ApplicationMainSight机器人：layout_toLeftOf =@ + ID / ApplicationMainEvent＆GT;＆LT; /按钮＆GT;

    ＆LT;按钮机器人：layout_height =WRAP_CONTENT的风格=@风格/ CKMainButton
        机器人：layout_width =FILL_PARENT机器人：文本=@字符串/景点
        机器人：ID =@ + ID / ApplicationMainSight机器人：layout_toLeftOf =@ + ID / ApplicationMainEvent＆GT;＆LT; /按钮＆GT;
＆LT; / LinearLayout中＆GT;

＆LT; LinearLayout中的android：layout_width =FILL_PARENT
    机器人：layout_height =WRAP_CONTENT＆GT;
    ＆LT;按钮机器人：layout_height =WRAP_CONTENT的风格=@风格/ CKMainButton
        机器人：layout_weight =1机器人：layout_width =FILL_PARENT
        机器人：文本=@字符串/ usergenerated机器人：ID =@ + ID / ApplicationMainUserGenerated＆GT;＆LT; /按钮＆GT;
    ＆LT;按钮机器人：layout_height =WRAP_CONTENT的风格=@风格/ CKMainButton
        机器人：layout_weight =1机器人：layout_width =FILL_PARENT
        机器人：文本=@字符串/游机器人：ID =@ + ID / ApplicationMainTour＆GT;＆LT; /按钮＆GT;
＆LT; / LinearLayout中＆GT;
＆LT; / LinearLayout中＆GT;
 

它看起来像这样：

我怎样才能acchieve布局看起来像图像在上面的顶部？

I want to make a layout similar to this one:

Four square buttons on the screen - each of those using half of the screen with/screen height (whichever is smaler). Independent of screen size/resolution.

I already tried to achieve this by using a LinearLayoutbut the buttons are ending up using the correct width, but still having the height of the background (not square any more).

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout android:layout_width="fill_parent"
    android:layout_height="wrap_content">
    <Button android:layout_height="wrap_content" style="@style/CKMainButton"
        android:layout_width="fill_parent" android:text="@string/sights"
        android:id="@+id/ApplicationMainSight" android:layout_toLeftOf="@+id/ApplicationMainEvent"></Button>

    <Button android:layout_height="wrap_content" style="@style/CKMainButton"
        android:layout_width="fill_parent" android:text="@string/sights"
        android:id="@+id/ApplicationMainSight" android:layout_toLeftOf="@+id/ApplicationMainEvent"></Button>
</LinearLayout>

<LinearLayout android:layout_width="fill_parent"
    android:layout_height="wrap_content">
    <Button android:layout_height="wrap_content" style="@style/CKMainButton"
        android:layout_weight="1" android:layout_width="fill_parent"
        android:text="@string/usergenerated" android:id="@+id/ApplicationMainUserGenerated"></Button>
    <Button android:layout_height="wrap_content" style="@style/CKMainButton"
        android:layout_weight="1" android:layout_width="fill_parent"
        android:text="@string/tours" android:id="@+id/ApplicationMainTour"></Button>
</LinearLayout>
</LinearLayout>

It's looking like this:

How can i acchieve the Layout to look like the image at the top above?

import android.content.Context;
import android.util.AttributeSet;
import android.widget.LinearLayout;

public class SquareLayout extends LinearLayout {
    // Desired width-to-height ratio - 1.0 for square
    private final double mScale = 1.0;

    public SquareLayout(Context context) {
        super(context);
    }

    public SquareLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

        int width = MeasureSpec.getSize(widthMeasureSpec);
        int height = MeasureSpec.getSize(heightMeasureSpec);

        if (width > (int)((mScale * height) + 0.5)) {
            width = (int)((mScale * height) + 0.5);
        } else {
            height = (int)((width / mScale) + 0.5);
        }

        super.onMeasure(
                MeasureSpec.makeMeasureSpec(width, MeasureSpec.EXACTLY),
                MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY)
        );
    }
}
