Hi all,
I'm trying to create a component using an xml layout file.
I defined a layout with some custom attributes. This layout is
inflated when user add it inside another layout. My problem is I
don't know the parent, so I pass null for the parent viewgroup when I
call inflate method.
You need to be the parent. You cannot inflate things into an ordinary View.
I think that's the reason why I see anything in my view.
Do you know how can I do (I don't want to redefine onDraw method
because I use existing component)
Below my xml layout and my custome class.
RelativeLayout
xmlns:android=http://schemas.android.com/apk/res/android;
android:layout_width=wrap_content
android:layout_height=wrap_content
ImageView
android:id=@+id/img_btn_option
android:layout_width=wrap_content
android:layout_height=wrap_content/
TextView
android:id=@+id/txt_btn_option
android:layout_width=wrap_content
android:layout_height=wrap_content
android:layout_toRightOf=@id/img_btn_option
android:textColor=@color/font_white
android:textStyle=bold/
/RelativeLayout
public class ButtonOptionsView extends View {
public ButtonOptionsView(Context context, AttributeSet attrs) {
super(context, attrs);
LayoutInflater li =
(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
RelativeLayout vg =
(RelativeLayout)li.inflate(R.layout.button_option, null);
TypedArray ta =
getContext().obtainStyledAttributes(attrs,R.styleable.ButtonOption);
((ImageView)vg.findViewById(R.id.img_btn_option)).setImageResource(ta.getResourceId(R.styleable.ButtonOption_image,
0));
((TextView)vg.findViewById(R.id.txt_btn_option)).setText(ta.getResourceId(R.styleable.ButtonOption_text,
0));
}
Make ButtonOptionsView extend RelativeLayout, and replace the
RelativeLayout in your XML with merge. Then, inflate into yourself.
