Converting Layout files to Java in android

I am facing problem to convert layout .xml files to Java I fave tried but failed to complete. I need anyones help to complete it. Need Help! Thanks in advance.

Here is my layout .xml file:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/lay"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <CheckBox android:id="@+id/checkbox_cheese"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/cheese"
        android:onClick="onCheckboxClicked"/>
</LinearLayout>

I just want to convert it to java which i have tried so far:

    LinearLayout linearLayout = (LinearLayout) findViewById(R.id.lay);
    CheckBox box = new CheckBox(this);
    box.setId(c);
    /* from here how to convert those below lines in Java         
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/cheese"
        android:onClick="onCheckboxClicked"
    */

I am in a good mood, or I would have just pointed you to Egor's comment; the tutorials are designed to show you the efficient ways to do what you want.

LinearLayout.LayoutParams boxParams = new LinearLayout.LayoutParams(
    LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
box.setLayoutParams(boxParams);
box.setText(R.string.cheese);

// if you want checkbox change listener
box.setOnCheckedChangedListener(new OnCheckedChangedListener(){
    @Override
    public void onCheckedChanged(RadioGroup group, int checkedId) {
        if (isChecked){
            // perform logic
        }
    }
};

// if you want on click listener functionality
box.setOnClickListener(new OnClickListener(){
    @Override
    public void onClick(View v){
        // perform logic
    }
}

linearLayout.addView(box);

Haven't tested it, don't know if it is bug free (may have missed something or done something wrong), but I can tell you that unless you plan on only doing this functionality and no other functionality you REALLY need to read into the basics of Android.

Do something like this:

View layout = ViewInflater.from(this).inflate(R.layout.layout, null); //your layout name

LinearLayout linearLayout = (LinearLayout) layout.findViewById(R.id.lay);
CheckBox box = (CheckBox) layout.findViewById(R.id.checkbox_cheese);

Now the box object will have all the properties assigned in the xml.

    android:layout_width="wrap_content"
    android:layout_height="wrap_content"

->setLayoutParams(..)

    android:text="@string/cheese"

->setText(..)

    android:onClick="onCheckboxClicked"

->setOnClickListener(..)
