How to add CustomView to Layout fromXML?

Question

I want to add this PaintingView() that is in this Activity from XML file.

public class Full extends Activity implements  ColorPickerDialog.OnColorChangedListener  {       
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
      setContentView(R.layout.paint);

      FrameLayout myFrameLayout = (FrameLayout) findViewById(R.id.framelayout);        
      myimage = (ImageView) findViewById(R.id.ImageView01);
      InputStream is = this.getResources().openRawResource(imageId1);
      originalBitmap = BitmapFactory.decodeStream(is);       
      myimage.setImageBitmap(originalBitmap);
      myimage.setScaleType(ScaleType.MATRIX);  

      mView = (PaintingView)findViewById(R.id.my_view);
      mView.setDrawingCacheEnabled(true);
      mView.setVisibility(View.INVISIBLE);
      final ImageButton paint = (ImageButton) findViewById(R.id.paint_button); 
         paint.setOnClickListener(new View.OnClickListener() {
         public void onClick(View view) {
            mView.setVisibility(View.VISIBLE);
         }
      });

      mPaint = new Paint();
      mPaint.setAntiAlias(true);
      mPaint.setDither(true);
      mPaint.setColor(0xFFFF0000);
      mPaint.setStyle(Paint.Style.STROKE);
      mPaint.setStrokeJoin(Paint.Join.ROUND);
      mPaint.setStrokeCap(Paint.Cap.ROUND);
      mPaint.setStrokeWidth(4);
      mBlur = new BlurMaskFilter(8, BlurMaskFilter.Blur.NORMAL);

</RelativeLayout>

Change as per your package name and classname....

Answer 2

you can add your custom view to your xml layout using

<ParentLayout>
<yourPackagePath.customviewname
//layout attributes come here
/>
</ParentLayout>

In the particular case of your question.

<pathtoyourclass.PaintingView
//layout attributes
/>
