Hi, i m new to android. I am trying to create custom component. developer wil use this component just like any other component like textview or editText in his layout.xml file. I want this component to be created and rendered by java file only. No layout xml is used. i am not sure whether to extend my class to View or ViewGroup or some layout and then add say textview and/or edittext. i tried by extending to View class but faced many problems in adding simple textVIew to it.
I am pasting following code. Problem with it is. I can see red square (which i think is a viewgroup) on emulator but not able to see textView added to it. Please help me. i have expressed my intentions above, to create forms or a form like reusable component. //My form impletation java file public class Form extends ViewGroup { AttributeSet attrSet; LinearLayout.LayoutParams layParams; Context moContext; public Form(Context context) { super(context); this.moContext = context; initForm(); } public Form(Context context, AttributeSet attributeSet) { super(context,attributeSet); this.attrSet = attributeSet; this.moContext = context; initForm(); } @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); setVisibility(VISIBLE); initForm(); } public void initForm() { setVisibility(VISIBLE); layParams = new LinearLayout.LayoutParams (LayoutParams.WRAP_CONTENT, LayoutParams.FILL_PARENT); layParams.gravity = LinearLayout.HORIZONTAL; layParams.setMargins(5, 5, 5, 5); setLayoutParams(layParams); setBackgroundColor(Color.RED); TextView textView = new TextView(getContext(), attrSet); textView.setText("AAAAAAAAAAAAA"); textView.setBackgroundColor(Color.YELLOW); textView.bringToFront(); invalidate(); } @Override protected void onLayout(boolean changed, int l, int t, int r, int b) { } } //layout.xml which will be used by some activity <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/ android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <com.android.custom.Form android:id="@+id/mform" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </LinearLayout> Please guide me through. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
