代码似乎改变了我的布局文件

Question

我有四个TableRows的TableLayout和四行中的四个按钮。 我有不同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;
    CountDownTimer countdown;
    CountDownTimer eins;
    CountDownTimer zwei;
    CountDownTimer drei;
    AlertDialog.Builder alertDialog;
    boolean einsstarted = false;
    boolean zweistarted = false;
    boolean dreistarted = false;
    boolean countdownstarted = false;

     Vibrator vibe;
    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

         vibe = (Vibrator) this.getSystemService(this.VIBRATOR_SERVICE) ;

        b = (Button) findViewById(R.id.button1);

问题是，如果一个按钮处于活动状态，它看起来像这样：

按钮位于彼此的顶部，它们很好奇地伸展开来。

所以，我测试了在开始时设置所有按钮，然后它看起来像这样（它应该看起来如何 - 所有按钮在另一个旁边）：

我的代码如何更改布局文件？

我的代码如何更改布局文件？

不是。 resource个文件无法在运行时更改。

正在发生的事情是，您将它们设置为GONE，以便其占用的空间可供其他Button使用。不要将它们设置为GONE，而是尝试制作它们INVISIBLE。这样，空间仍将被占用，但它们不会显示。

只是一个建议但你可以在xml中设置visibility来清理你的Java文件。这只是一个偏好，但这可能就是我要做的。另外，
