Fwd: [android-developers] extending view class not working but not throwing errors or force close
TreKing I should clarify, I have a button in XML, however java setContentView points to another created java class. It is this class that is meant to be able to create a canvas colored blue with an image of a cloud 'floating' across it, (if understand the tutorial). This is the first time I have tried to create using this type of setContentView set up, and am obviously missing something. -- Forwarded message ------ From: Chris Cullington-Johnson Date: Wed, Oct 26, 2011 at 1:50 PM Subject: Re: [android-developers] extending view class not working but not throwing errors or force close To: android-developers@googlegroups.com There lies the problem, I am lost.

[android-developers] extending view class not working but not throwing errors or force close
Hello all
I am doing a tutorial through you tube I have my java correct but still my
button wont enable the view class, it's like button is not linked. I think
my manifest might be lacking something, I have listed that below java stuff.
My code is
This is the first java class that references java view class
package com.cornboyz.thebasics;
import android.app.Activity;
import android.os.Bundle;
public class tutorialFive extends Activity {
Cornboyz sweetBK;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
sweetBK = new Cornboyz(tutorialFive.this);
setContentView(sweetBK);
}
}
This is the java meant to create rectangle (without using XML if I
understand this all correctly)
package com.cornboyz.thebasics;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Rect;
import android.view.View;
public class Cornboyz extends View{
Bitmap cloud;
int x = 0;
int y = 0;
Paint paint = new Paint();
public Cornboyz(Context context) {
super(context);
// TODO Auto-generated constructor stub
cloud = BitmapFactory.decodeResource(getResources(), R.drawable.cloud1);
}
@Override
protected void onDraw(Canvas canvas) {
// TODO Auto-generated method stub
super.onDraw(canvas);
//set background
Rect cBK = new Rect();
cBK.set(0, 0, canvas.getWidth(), canvas.getHeight());
Paint pBlue = new Paint();
pBlue.setColor(Color.BLUE);
pBlue.setStyle(Paint.Style.FILL);
canvas.drawRect(cBK, pBlue);
drawCloud(x, y, canvas);
if(x < canvas.getWidth()){
x = x+10;
}else{
y = y+10;
x = 0;
}
invalidate();
}
private void drawCloud(int x2, int y2, Canvas canvas) {
// TODO Auto-generated method stub
canvas.drawBitmap(cloud, x2, y2, paint);
}
}
This is the Manifest
http://schemas.android.com/apk/res/android";
package="com.cornboyz.thebasics"
android:versionCode="1"
android:versionName="1.0">

Re: [android-developers] NEWBIE needs help with Android Tab Widget tutorial
thanks TreKing I ended up figuring this one out, finally. Now stuck on HelloGoogleMapView tutorial. I am refusing to give in this time and am doing a lot of reading about how to put the code together cause I am obviously missing something.

[android-developers] NEWBIE needs help with Android Tab Widget tutorial
I have just joined the Android World and am lovn it, however having a bit of trouble with some of the tutorials, in particular the Hello Tab Widget one. Particular part states "Notice that this doesn't use a layout file. Just create a TextView, give it some text and set that as the content. Duplicate this for each of the three activities, and add the corresponding tags to the Android Manifest file." I think this is where I am going wrong, I don't fully understand how to add "the corresponding tags in manifest file". see below for my code what have I done (or not done). My app now doen't display errors but will not run it shows the following error " The appication HelloTabWidget (process Tab.Widget) has stopped unexpectedly.." http://schemas.android.com/apk/res/android"; * package=*"Tab.Widget" * android:versionCode=*"1" * android:versionName=*"1.0"*> -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
