how to move edittext or imageview in only that particular relative layout?

Question

    public class MyActivity extends Activity implements View.OnTouchListener {

    TextView _view;
    ViewGroup _root;
    private int _xDelta;
    private int _yDelta;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        _root = (ViewGroup)findViewById(R.id.root);

        _view = new TextView(this);
        _view.setText("TextView!!!!!!!!");

        RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(150, 50);
        layoutParams.leftMargin = 50;
        layoutParams.topMargin = 50;
        layoutParams.bottomMargin = -250;
        layoutParams.rightMargin = -250;
        _view.setLayoutParams(layoutParams);

        _view.setOnTouchListener(this);
        _root.addView(_view);
    }

    public boolean onTouch(View view, MotionEvent event) {
        final int X = (int) event.getRawX();
        final int Y = (int) event.getRawY();
        switch (event.getAction() & MotionEvent.ACTION_MASK) {
            case MotionEvent.ACTION_DOWN:
                RelativeLayout.LayoutParams lParams = (RelativeLayout.LayoutParams) view.getLayoutParams();
                _xDelta = X - lParams.leftMargin;
                _yDelta = Y - lParams.topMargin;
                break;
            case MotionEvent.ACTION_UP:
                break;
            case MotionEvent.ACTION_POINTER_DOWN:
                break;
            case MotionEvent.ACTION_POINTER_UP:
                break;
            case MotionEvent.ACTION_MOVE:
                RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams) view.getLayoutParams();
                layoutParams.leftMargin = X - _xDelta;
                layoutParams.topMargin = Y - _yDelta;
                layoutParams.rightMargin = -250;
                layoutParams.bottomMargin = -250;
                view.setLayoutParams(layoutParams);
                break;
        }
        _root.invalidate();
        return true;
    }}

I have doing this code for moving edittext and imageview.It's moving fine but it moves also outside the relative layout.I have to put restriction for moving only in particular layout.Anyone have suggestion?

Try using the Absolute layout. – GrIsHu Oct 17 '13 at 09:56 — GrIsHu, Oct 17 '13 at 09:56
@GrIsHu, I try absolute layout but it not set margin. – immodi Oct 23 '13 at 05:24 — immodi, Oct 23 '13 at 05:24

Check out Drag & Drop Functionality Code below which i have implemented:

DragAndDrop.java

  public class DragAndDrop extends Activity
   {
private ImageView m_ivImage, m_ivImage1;
private int m_counter = 0;
float m_lastTouchX, m_lastTouchY, m_posX, m_posY, m_prevX, m_prevY, m_imgXB, m_imgYB, m_imgXC, m_imgYC, m_dx, m_dy;

@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    m_context = this;

    m_prevX = 0;
    m_prevY = 0;
    m_imgXB = 50;
    m_imgYB = 100;
    m_imgXC = 150;
    m_imgYC = 100;

    m_ivImage = (ImageView) findViewById(R.id.ivImage);
    m_ivImage1 = (ImageView) findViewById(R.id.ivImage1);
    m_llTop = (LinearLayout) findViewById(R.id.llTop);
    m_alTop = (AbsoluteLayout) findViewById(R.id.alTop);
    m_btnAddView = (Button) findViewById(R.id.btnAdd);
    m_btnRemove = (Button) findViewById(R.id.btnRemove);

    m_ivImage.setOnTouchListener(m_onTouchListener);

thanks for reply but it's not working for me.when I used absolute layout, that view is not moving.It stay static.I need only layout's current height and width in Action view as like you define in if condition.Is this possible? — immodi, Oct 23 '13 at 12:59
Yes you can get layout's current height and width as i have defined and restrict it in my code. You may have missed the view's touch listener to move it. — GrIsHu, Oct 23 '13 at 13:03
No..I cant restrict it in only LinearLayout.And second problem is When I moving latest edittext or imageview, it also moving oldest edittext or imageview.I added you in Google+.Any solution for this? — immodi, Oct 23 '13 at 15:04
Have you tried with my code ? It works perfect. Just try with my code. — GrIsHu, Oct 24 '13 at 04:27
ok..apart from this problem.Can we store height,width,xaxis and yaxis of layout and inner layouts? — immodi, Oct 24 '13 at 08:32
Yes you can store it. But its bit complicated to take each view's height,width,xaxis,yaxis etc.. and store it and manage it. — GrIsHu, Oct 24 '13 at 08:38
Actually I stored height,width,xaxis and yaxis of layout and as per this data layout will displayed.Is this possible? — immodi, Oct 24 '13 at 08:46
@GrlsHu, thanks for replied..I got it.I make layout from database. — immodi, Oct 31 '13 at 06:17
