Dynamic layout

Question

I have a layout that may be a little unusual. The structure is as follows:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <org.CustomSurfaceView
        android:id="@+id/page_flip"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_marginBottom="20dip" />

    <org.customRelativeLayout
        android:id="@+id/note"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:visibility="gone" />
</FrameLayout>

My customRelativeLayout at the bottom of the XML also has an XML layout:

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="200dp"
    android:layout_height="200dp"
    android:background="@drawable/my_background"
    android:id="@+id/note_layout">
    <TextView android:id="@+id/note"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:singleLine="false"
        android:layout_margin="5dp"
        android:textColor="#000000" />
</LinearLayout>

My CustomRelativeLayout:

public class CustomRelativeLayout extends RelativeLayout implements OverlayView {

    private TextView mNoteText;
    private LinearLayout mLinearLayout;
    public int mX = 0;
    public int mY = 0;
    public boolean mShow;

    public CustomRelativeLayout(Context context, AttributeSet attrs) {
        super(context, attrs);

        LayoutInflater li = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        li.inflate(R.layout.note, this);
        mNoteText = (TextView) findViewById(R.id.note);
        mLinearLayout = (LinearLayout) findViewById(R.id.note_layout);

        mLinearLayout.setOnTouchListener(new OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                Log.e("touched");
                mX = (int) event.getX() - 100;
                mY = (int) event.getY() - 100;
                invalidate();
                return false;
            }
        });
    }

    @Override
    public void hide() {
        mShow = false;
        setVisibility(View.GONE);
    }

    @Override
    public boolean isVisible() {
        return isVisible();
    }

    @Override
    protected void onDraw(Canvas canvas) {
        Log.e("Drawing the postit");
        Matrix matrix = new Matrix();
        matrix.postTranslate(mX, mY);
        canvas.setMatrix(matrix);
        super.onDraw(canvas);
    }

    @Override
    public void setContent(Object content) {
        if (content != null && content instanceof Content) {
            Content noteContent = (Content) content;
            if (noteContent.getText() != null) {
                mNoteText.setText(noteContent.getText());
            } else {
                mNoteText.setText("");
            }
        }
        mNoteText.invalidate();
        mLinearLayout.invalidate();
    }

    @Override
    public void show() {
        mShow = true;
        setVisibility(View.VISIBLE);
    }
}

What I want to do: I want to be able to change the position of my CustomRelativeLayout. He must follow my touch. It is smaller than the SurfaceView, and should "slide" higher, following my touch ...

There are two problems:

• binding of onTouchListener to mlinearLayout (in CustomRelativeLayout) is launched only once and only for ACTION_DOWN. I see log output only once
• A note never changes position, it never redraws with a changed matrix ... I see the result indicated in onDraw, never after a touch has occurred.

:

public TextNoteOverlay(Context context, AttributeSet attrs) {
    super(context, attrs);

    LayoutInflater li = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    li.inflate(R.layout.textnote, this);

    mLinearLayout = (LinearLayout) findViewById(R.id.textnote_layout);

    setOnTouchListener(new OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            mLinearLayout.getHitRect(mNoteRect);
            if (mNoteRect.contains((int) event.getX(), (int) event.getY())) {
                if (event.getAction() == MotionEvent.ACTION_DOWN) {
                    mStartX = (int) event.getX() - mLinearLayout.getLeft();
                    mStartY = (int) event.getY() - mLinearLayout.getTop();
