我创建了一个动态创建 50 个按钮的 android 应用程序，效果很好，但问题是当我使用下面给出的代码为这些按钮动态添加一些背景颜色时，我的视图变得很糟糕

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

我的代码如下所示，谁能告诉我一些解决方案

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);
            }
        }
    }

}

您应该添加一些边距，以便为这些按钮留出一些喘息的空间。

// 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);
