實現鍵盤佈局，沒有嵌套的重量和固定的尺寸在xml

Question

我有一個嵌套的權重，這對於pefrormance很糟糕的佈局。 如何製作計算器鍵盤（例如沒有重量的計算器鍵盤），但是在不給予固定「sp」或「dp」大小的情況下節省按鈕大小，無論屏幕上的分辨率如何，都必須縮放鍵盤

，我發現這裏的解決方案CommonsWare answer這裏Che Jame answer

但爲什麼他們說：「使用Android：layout_weight =」鍵上的兩個」 1" Eclipse的說我必須得到權重的蘆葦... 是還有其他解決方案嗎？或者在android平臺上不可能？ 這裏是我有它使用嵌套的權重，而代碼如下

我要救這個觀點，但bithout嵌套的權重和按鈕必須是相同的大小，更大然後「包裝內容」參數

感謝您的任何建議。

如suggested由Android LinearLayouts應由RelativeLayout的或GridLayout的來代替。在大多數情況下，RelativeLayout就足夠了，但在這種情況下GridLayout可以派上用場。你可以寫下類似於下面的代碼來實現你想要的東西：

<GridLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_gravity="center" 
    android:columnCount="4" 
    android:orientation="horizontal" > 

    <Button 
     android:layout_column="3" 
     android:text="/" /> 

    <Button android:text="1" /> 

    <Button android:text="2" /> 

    <Button android:text="3" /> 

    <Button android:text="*" /> 

    <Button android:text="4" /> 

    <Button android:text="5" /> 

    <Button android:text="6" /> 

    <Button android:text="-" /> 

    <Button android:text="7" /> 

    <Button android:text="8" /> 

    <Button android:text="9" /> 

    <Button 
     android:layout_gravity="fill" 
     android:layout_rowSpan="3" 
     android:text="+" /> 

    <Button 
     android:layout_columnSpan="2" 
     android:layout_gravity="fill" 
     android:text="0" /> 

    <Button android:text="00" /> 

    <Button 
     android:layout_columnSpan="3" 
     android:layout_gravity="fill" 
     android:text="=" /> 

</GridLayout>
