Hi,

It seems that my attributes are not being read. I have the following main.xml:

Code: Select all

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:id="@+id/layMain"
    >
   
    <android.happer.Mens
       android:id="@+id/myView"
       android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:background="#000000FF"
          android:visibility="invisible"
       />
       
   
</LinearLayout>



It goes wrong at the point where i want to give my custum View a backgground color. The visibilty doesn't do his work either.

But, when i put the following lines in my Mens class (which extends the View class):

Code: Select all

setBackgroundColor(Color.BLUE );
// setVisibility(INVISIBLE);


It works. Thus, when i invoke the methods in my class file it works fina, but when use the lines in the xml file, it doesn't work. How is that?

Thnx in advance

Probably because you override onDraw().

Ain't that strange? I mean, when i omit onDraw() how can i put a drawing on the screen? In this case i draw a simple line, but this should be a player. So if i omit onDraw() how do i solve this?

you can call super.onDraw()

So, on my Mens class i call super.onDraw(); (which point at the View class right?)

But if i do that, where do i draw my object?

in onDraw() of course

I don't get it.

This is my entire class:

Code: Select all

package android.happer;

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Bitmap.Config;
import android.util.AttributeSet;
import android.view.View;

public class Mens extends View {
   
      public Mens(Context context, AttributeSet attrs)
      {
         super(context);
      }
   
   protected void onDraw(Canvas canvas)
    {
      Paint p = new Paint();
      p.setColor(Color.RED);
      
      canvas.drawLine(15, 15, 25, 5, p);
      
      //setBackgroundColor(Color.BLUE );
      // setVisibility(INVISIBLE);
      
    }
}



What do i have to do, to make the arttributes in the XML file work?(background and visibility)

It didn't work. My background is still default and i can still see my line.

main.xml:

Code: Select all

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:id="@+id/layMain"
    >
   
    <android.happer.Mens
       android:id="@+id/myView"
       android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:background="#FF000000"
          android:visibility="invisible"
       />
       
   
</LinearLayout>



Hmm, k, then I don't know, sorry.

Okee, thnx anyway
