在android中着色按钮时出现坏视图

Question

我已经创建了一个android应用程序，它动态地创建了50个按钮，工作非常完美，但问题是，当我使用下面给出的代码动态地为这些按钮添加背景颜色时，我的视图会变差

buttons[i][j].setTextColor(Color.BLACK);
buttons[i][j].setBackgroundColor(Color.GREEN);

我的代码如下所示，有人能告诉我一些解决办法吗？

我的安卓平台是2.3.3

import android.app.Activity;
import android.os.Bundle;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.LinearLayout;

public class MyMain extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.mymain);
        createCalender();
    }
    public void createCalender()
    {  
        LinearLayout layoutVertical = (LinearLayout) findViewById(R.id.liVLayout);
        LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(
        LayoutParams.MATCH_PARENT,
        LayoutParams.MATCH_PARENT, 1.0f);
        LinearLayout rowLayout=null;
        Button[][] buttons = new Button[10][5]; 
        int count=51;
        int tab=1;
        for (int i = 0; i<10; i++) 
        {
            if(count%5==1)
            {
                rowLayout = new LinearLayout(this);
                rowLayout.setWeightSum(5);
                layoutVertical.addView(rowLayout,param);
                count=count-5;
            }
            for(int j=0;j<5;j++)
            {
                buttons[i][j]=new Button(this);
                buttons[i][j].setText(""+tab);
                buttons[i][j].setHeight(35);
                buttons[i][j].setWidth(75);                                            
                buttons[i][j].setTextColor(Color.BLACK);
                buttons[i][j].setBackgroundColor(Color.GREEN);
                tab++;

                rowLayout.addView(buttons[i][j],param);
            }
        }
    }

}

你应该增加一些空白处，让这些按钮有喘息的空间。

// First try with WRAP_CONTENT
LinearLayout.LayoutParams paramForButtons = new LinearLayout.LayoutParams(
                                                LayoutParams.WRAP_CONTENT,
                                                LayoutParams.WRAP_CONTENT, 1.0f);

// If the buttons look too small using WRAP_CONTENT, change to MATCH_PARENT
// Set the margins in this case
LinearLayout.LayoutParams paramForButtons = new LinearLayout.LayoutParams(
                                                LayoutParams.MATCH_PARENT,
                                                LayoutParams.MATCH_PARENT, 1.0f);


paramForButtons.setMargins(10, 10, 10, 10);

将for循环的最后一行替换为：

rowLayout.addView(buttons[i][j],paramForButtons);
