Question

I have created an array of buttons for my app. Now I am not able to manage the layout of these array of buttons. As a result of this, whenever I add image or change width of the buttons it’s going out of the horizontal screen of the device. So is there any way to manage these Array of buttons so that they can fit in any screen size.
Here is my code:

XML:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <LinearLayout
    android:id="@+id/liVLayout"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">
    </LinearLayout>

    <LinearLayout
    android:id="@+id/liVLayout1"
    android:orientation="vertical"
    android:layout_below="@+id/liVLayout"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">

    <TextView android:text="All Contacts" 
        android:id="@+id/textView1" 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:textColor="@android:color/black"
        android:background="#808080">
    </TextView> 
    </LinearLayout>
</RelativeLayout>

Java:

public class CalenderForm extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    createCalender();
}
public void createCalender()
{
    RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams
    (
            RelativeLayout.LayoutParams.WRAP_CONTENT,
            RelativeLayout.LayoutParams.WRAP_CONTENT
    );  
    LinearLayout layoutVertical = (LinearLayout) findViewById(R.id.liVLayout);
    LinearLayout rowLayout=null;
    Button[][] buttons = new Button[6][7]; 
    int count=43;
    for (int i = 0; i<6; i++) 
    {
        if(count%7==1)
        {
            rowLayout = new LinearLayout(this);
            layoutVertical.addView(rowLayout,p);
            count=count-7;
        }
        for(int j=0;j<7;j++)
        {
            buttons[i][j]=new Button(this);
            buttons[i][j].setBackgroundResource(R.drawable.icon); 
            rowLayout.addView(buttons[i][j], p);
        }
    }
}

}

just replace this code.use weightsum property of linear and layout_weight of buttons.

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

public class MainActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        createCalender();
    }
    public void createCalender()
    {  
        LinearLayout layoutVertical = (LinearLayout) findViewById(R.id.liVLayout);
        LinearLayout rowLayout=null;
        Button[][] buttons = new Button[6][7]; 
        int count=43;
        **LayoutParams param = new LinearLayout.LayoutParams(
                LayoutParams.FILL_PARENT,
                LayoutParams.FILL_PARENT,1);**

        for (int i = 0; i<6; i++) 
        {
            if(count%7==1)
            {
                rowLayout = new LinearLayout(this);
                **rowLayout.setWeightSum(7);**
                **layoutVertical.addView(rowLayout,param);**
                count=count-7;
            }
            for(int j=0;j<7;j++)
            {
                buttons[i][j]=new Button(this);
                buttons[i][j].setBackgroundResource(R.drawable.icon);
                **rowLayout.addView(buttons[i][j],param);**
            }
        }
    }
