and this is my class file

public class SingleWeatherInfoView extends LinearLayout {

        this.myWeatherImageView = new ImageView(context);
        this.myWeatherImageView.setImageDrawable(getResources().getDrawable(
                R.drawable.dunno));

        /* Setup the textView that will show the temperature. */
        this.myTempTextView = new TextView(context);
        this.myTempTextView.setText("? °C");
        this.myTempTextView.setTextSize(16);
        this.myTempTextView.setTypeface(Typeface
                .create("Tahoma", Typeface.BOLD));

        /* Add child views to this object. */
        this.addView(this.myWeatherImageView, new LinearLayout.LayoutParams(
                LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
        this.addView(this.myTempTextView, new LinearLayout.LayoutParams(
                LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
    }


    public void reset() {
        this.myWeatherImageView.setImageDrawable(getResources().getDrawable(
                R.drawable.dunno));
        this.myTempTextView.setText("? °C");
    }

    /** Sets the Child-ImageView of this to the URL passed. */
    public void setRemoteImage(URL aURL) {
        try {
            URLConnection conn = aURL.openConnection();
            conn.connect();
            InputStream is = conn.getInputStream();
            BufferedInputStream bis = new BufferedInputStream(is);
            Bitmap bm = BitmapFactory.decodeStream(bis);
            bis.close();
            is.close();
            this.myWeatherImageView.setImageBitmap(bm);
        } catch (IOException e) {
            /* Reset to 'Dunno' on any error. */
            this.myWeatherImageView.setImageDrawable(getResources()
                    .getDrawable(R.drawable.dunno));
        }
    }

    public void setTempCelcius(int aTemp) {
        this.myTempTextView.setText("" + aTemp + " °C");
    }

    public void setTempFahrenheit(int aTemp) {
        this.myTempTextView.setText("" + aTemp + " °F");
    }

    public void setTempFahrenheitMinMax(int aMinTemp, int aMaxTemp) {
        this.myTempTextView.setText("" + aMinTemp + "/" + aMaxTemp + " °F");
    }

    public void setTempCelciusMinMax(int aMinTemp, int aMaxTemp) {
        this.myTempTextView.setText("" + aMinTemp + "/" + aMaxTemp + " °C");
    }

    public void setTempString(String aTempString) {
        this.myTempTextView.setText(aTempString);
    }
}

What causes these errors?

why are you suing "this" key word every where. Are you sure you can add views to this class.. — ngesh, Aug 09 '11 at 05:44

It looks like the SingleWeatherInfoView class you are using doesn't properly support XML inflation. You should try creating instances of it from code instead of XML and see if that works.

I had the same problem and the error I was making was putting an incorrect address for the package SingleWeatherInfoView in main.xml:

com.beach.alpha.SingleWeatherInfoView

Be sure that your project has this path.

Just move all the logic after Setup ImageView... into a new method init(...) and call it from where you moved the logic.
Create public SingleWeatherInfoView(Context context, AttributeSet attrs) { super(context, attrs); init(...); }
