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!
