代码似乎改变我的布局文件

Question

我有一个TableLayout与四个TableRows和四个按钮中的每一行。 我有不同的屏幕分辨率的大问题，所以我建立了我的布局文件新。

首先，我给你我的代码：

public class MainActivity extends Activity { 

    Button b,b2,b3,b4, b5,b6,b7,b8,b9,b10,b11,b12,b13,b14,b15,b16,b17,b18,b19,b20; 
    //b21,b22,b23,b24; 


    ArrayList<Button> arr = new ArrayList<Button>(); 

    MediaPlayer mp; 
    Button aktuell; 
    TextView tv; 
    String playtone =""; 
    String shouldvibra =""; 
    TextView tvPunktestand; 
    int count = 0;

就像你可以看到，我的目标是建立一个按钮可见和所有其他无形。每隔几毫秒这应该改变。

这是我的布局文件：

<TableLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="wrap_content"

    android:background="@drawable/bg" 
    android:stretchColumns="0,1,2,3,4,5" 


    tools:context=".MainActivity" > 

    <TableRow 
     android:id="@+id/tableRow1" 

     android:paddingTop="22dp" 
     android:layout_weight="1"> 

     <Button 
      android:id="@+id/button1" 
      android:text="1" 
      android:background="@drawable/willi"> 
     </Button> 
     <Button 
      android:id="@+id/button2"

      </Button> 
        <Button 
         android:id="@+id/button8" 
      android:text="4" 
      android:layout_marginLeft="10dp" 
      android:background="@drawable/willi"> 
      </Button> 


    </TableRow> 
    and so on.... 

</TableLayout> 

的问题是，如果一个按钮被激活，它看起来像这样：

的按钮躺在彼此顶部他们好奇地伸展着。

所以，我测试设置所有的按钮上可见的开始，那么它看起来像这样（它应该如何看 - 其他旁边所有的按钮）：

这怎么可能，我的代码更改我的布局文件？

Answer 1

这可能是我的代码更改我的布局文件？

不是。 resource文件不能在运行时更改。

它看起来像是发生的是，你将它们设置为GONE，所以它将占用的空间可用于其他Button s。而不是将它们设置为GONE，请尝试将它们设置为INVISIBLE。这样的空间仍然会被占用，但他们不会显示。

只是一个建议，但你可以在xml中设置visibility这将清理你的Java文件。这只是一个偏好，但这可能是我会做的。另外，
