Android Custom View Problem

Hi Guys i have been fighting with this problem and don't know what is the reason. I have a simple layout as follows <?xml version="1.0" encoding="utf-8"?> <view xmlns:android="http://schemas.android.com/apk/res/android" class="com.dinash.notepad.NotePade$LinedEditText" />

and the activity class is as follows:

public class NotePade extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
}

public class LinedEditText extends EditText {
    private Rect mRect;
    private Paint mPaint;
    // we need this constructor for LayoutInflater
    public LinedEditText(Context context, AttributeSet attrs) {
        super(context, attrs);
        mRect = new Rect();
        mPaint = new Paint();
        mPaint.setStyle(Paint.Style.FILL_AND_STROKE);
        // mPaint.setColor(R.color.edit_note_line); //SET YOUR OWN COLOR
        // HERE
        mPaint.setColor(Color.RED); // SET YOUR OWN COLOR HERE
    }

    @Override
    protected void onDraw(Canvas canvas) {
        // int count = getLineCount();
        int height = getHeight();
        // int height = 100;
        int line_height = getLineHeight();
        int count = height / line_height;
        if (getLineCount() > count)
            count = getLineCount();// for long text with scrolling

        Rect r = mRect;
        Paint paint = mPaint;
        int baseline = getLineBounds(0, r);// first line
        for (int i = 0; i < count; i++) {
            canvas.drawLine(r.left, baseline + 1, r.right, baseline + 1,
                    paint);
            baseline += getLineHeight();// next line
        }
        super.onDraw(canvas);
    }
}

}

when i launch the application i keep on getting this error05-26 11:31:21.604: ERROR/AndroidRuntime(1537): Caused by: android.view.InflateException: Binary XML file line #2: Error inflating class com.dinash.notepad.NotePade$LinedEditText

and following that

05-26 11:31:21.604: ERROR/AndroidRuntime(1537): Caused by: java.lang.NoSuchMethodException: LinedEditText(Context,AttributeSet)

Could any body tel what the problem is... Thanks in advance

I think write your custom view in a separate class and your layout should be like this...

<com.dinash.notepad.LinedEditText></com.dinash.notepad.LinedEditText>

Move your custom view into separate file.

You need to make your inner class static. Otherwise, it would always require an instance of NotePade to give it an initialization context.

See here.
