    {
        如果（计数％5 == 1）
        {
            的RowLayout =新的LinearLayout（本）;
            rowLayout.setBackgroundColor（Color.BLACK）;
            rowLayout.setWeightSum（5）;
            layoutVertical.addView（的RowLayout，参数）;
            数=计-5;
        }
        为（中间体J = 0; J＆小于5; J ++）
        {
            按钮[i] [j]的=新按钮（本）;
            按钮[i] [j]的.setText（+标签）;
            按钮[i] [j]的.setHeight（55）;
            按钮[i] [j]的.setWidth（80）;
            按钮[i] [j]的.setTextColor（Color.BLACK）;
            按钮[i] [j]的.setBackgroundColor（Color.GREEN）;            标签++;            rowLayout.addView（按钮[i] [j]时，参数）;        }
    }
}}
 

解决方案

在按钮[i] [j]的.setBackgroundColor（Color.GREEN）;

 按钮[i] [j]的.setOnClickListener（新OnClickListener（）{    @覆盖
    公共无效的onClick（视图v）{        v.setBackgroundColor（Color.GRAY）; //可以任意选择颜色        新的处理程序（）。postDelayed（新的Runnable（）{            公共无效的run（）{                v.setBackgroundColor（Color.GREEN）;                //按钮单击code这里
            }        }，100L）;到任何适合//改变这个值    }}）;
 

i've created an android application which creates 50 button dynamically,which works perfectly, but the problem is when i put some background color for these buttons dynamically the press effect of the buttons is being lost

can anyone please tell me some solution for retaining the press effect of the button click
my code is as given below
my Android Platform is 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.WRAP_CONTENT,
            LayoutParams.WRAP_CONTENT, 1.0f);


    param.setMargins(10, 10, 10, 10);


    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.setBackgroundColor(Color.BLACK);
            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(55);
            buttons[i][j].setWidth(80);
            buttons[i][j].setTextColor(Color.BLACK);
            buttons[i][j].setBackgroundColor(Color.GREEN);

            tab++;

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

        }
    }
}

}

解决方案

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

buttons[i][j].setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {

        v.setBackgroundColor(Color.GRAY); // Choose whichever color

        new Handler().postDelayed(new Runnable() {

            public void run() {

                v.setBackgroundColor(Color.GREEN);

                // Button Click Code Here
            }

        }, 100L);    // Change this value to whatever is suitable

    }

});
