 Hi,

I've implemented a custom CheckBox view and faced a probelm with
adding text to it.

Here's my implementation:

public class MyCheckBox extends CheckBox{

private int imgResourceFocusedChecked, imgResourceFocusedNotChecked,
imgResourceNotFocusedChecked, imgResourceNotFocusedNotChecked;

        public MyCheckBox(Context context){
                super(context);
        }

        public MyCheckBox(Context context, AttributeSet attrs) {
                super(context, attrs);
                init(attrs);
        }

        public MyCheckBox(Context context, AttributeSet attrs, int defStyle)
{
                super(context, attrs, defStyle);
                init(attrs);
        }

        private void init(AttributeSet attrs){
                TypedArray a = getContext().obtainStyledAttributes(attrs,
R.styleable.MyCheckBox);
                imgResourceFocusedChecked = a.getResourceId
(R.styleable.MyCheckBox_checkboxFocusedChecked, -1);
                imgResourceFocusedNotChecked = a.getResourceId
(R.styleable.MyCheckBox_checkboxFocusedNotChecked, -1);
                imgResourceNotFocusedChecked = a.getResourceId
(R.styleable.MyCheckBox_checkboxNotFocusedChecked, -1);
                imgResourceNotFocusedNotChecked = a.getResourceId
(R.styleable.MyCheckBox_checkboxNotFocusedNotChecked, -1);
                strResourceText = a.getResourceId
(R.styleable.MyCheckBox_checkboxText, -1);
        }

        public void onDraw(Canvas canvas){
                if (this.isChecked()){
                        if (this.isFocused()){
                                
this.setBackgroundResource(imgResourceFocusedChecked);
                        } else {
                                
this.setBackgroundResource(imgResourceNotFocusedChecked);
                        }
                } else {
                        if (this.isFocused()){
                                
this.setBackgroundResource(imgResourceFocusedNotChecked);
                        } else {
                                
this.setBackgroundResource(imgResourceNotFocusedNotChecked);
                        }
                }
        }
}


Then from my layout xml I do something like:

<MyCheckBox
        android:id="@+id/checkBox"
        android:layout_width="32px"
        android:layout_height="32px"
        android:text="This is a check box."
        cb:checkboxFocusedChecked="@drawable/cb_focused_checked"
        cb:checkboxFocusedNotChecked="@drawable/cb_focused_not_checked"
        cb:checkboxNotFocusedChecked="@drawable/cb_not_focused_checked"
        cb:checkboxNotFocusedNotChecked="@drawable/
cb_not_focused_not_checked"
        style="@style/myStyle"/>

However, the text never comes up. Using the same technique with Button
and EditText views works fine , but not with check boxes. Hope to get
an advice of how to implement the proper behaviour. Thanks!

>From a remote machine we are sending some UDP packets to our Android

The port we are using is:49152 and static ip at both ends

Is this port supported by android emulator?
What is the solution to get UDP packets to be able to reach till the
emulator?

Kindly give solution for the same,
