Android, overlapping imageViews

I am creating programatically ImageViews and dragging them in the same layout.
I would like to disable overlapping for this ImageView. Is there a setting to be applied to disable overlap when I create every ImageView programatically or something else ?

It is not very clear what exactly You want to do, but if I am understand You the right way, You want to set some ImageViews to a layout programmatically? Why are Your Views overlapping? I think You have to set the layout Paramaters for Your view container:
//after onCreate in the activity, create the LinearLayout (for example)
//and set the LayoutParams, if You have no one declared in Your xml
LinearLayout linearLayout= new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.VERTICAL);
linearLayout.setLayoutParams(new LayoutParams(
LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT));
//then create the imageView, set the image inside and add it to the container
ImageView imageView = new ImageView(this);
imageView.setImageResource(R.drawable.your_image);
imageView.setLayoutParams(new LayoutParams(
LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT));
linearLayout.addView(imageView);
//set all as content
setContentView(linearLayout);
Have You done it in this way? If not, try it, also if You want to set multiple imageViews or some other Layout, You have to play a little bit with the LayoutParams.

Partial redraw -> invalidate (Rect rect)

In my onDraw I have all code needed to build my entire view but how can I detect if I want to perform only a partial redraw.
I guess a partial redraw should be triggered by calling canvas.invalidate(Rect rect);
Right?
In developer settings of my device I enabled “Show screen updates” but this always tells me that my entire screen is redrawn…
Below you see a screenshot of my app:
As you can see it is a calendar and I want to give the user a visual feedback when an entry is clicked (let’s say a red border around)…
I’ve already seen some samples but they either use a bitmap or lots of member variables to execute just the code needed for redrawing specific region in onDraw…
Can anyone tell me what’s the best way to implement such a feature?
UPDATE:
On my first draw Canvas.getClipBounds() returns the following rect:
Rect(0, 0 - 1200, 1800)
when I call invalidate(new Rect(304, 748 - 529, 902)) and check getClipBounds() again in onDraw() it still has the same value.
UPDATE2 (my code):
#Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN: {
_pTouchDown = new PointF(event.getX(), event.getY());
downX = event.getX();
downY = event.getY();
entrySelected = hasTimeRecordAt(downX, downY);
if (entrySelected != null) {
Rect rInvalidate = new Rect((int) entrySelected.get_Selected().left, (int) entrySelected.get_Selected().top, (int) entrySelected.get_Selected().right,
(int) entrySelected.get_Selected().bottom);
invalidate(rInvalidate);
}
return false;
}

UPDATE4:
setContentView(R.layout.test_calendar);
// _cal = (Calendar) findViewById(R.id.calendar);
_cal = new Calendar(this);
_dayHeader = (DayHeader) findViewById(R.id.dayHeader);
final ScrollView sv = (ScrollView) findViewById(R.id.m_svMultiRoot1);
sv.addView(_cal);
same result:
I in onTouch I pass Rect(172, 748 - 265, 902) and in onDraw I get Rect(0, 0 - 720, 1800)
UPDATE 5:

private static final String TAG = "null";
Rect clip = new Rect();
public V(Context context) {
super(context);
int[] colors = { 0xff000000, 0xffff0000, 0xffffffff };
Drawable d = new android.graphics.drawable.GradientDrawable(android.graphics.drawable.GradientDrawable.Orientation.TOP_BOTTOM, colors);
setBackgroundDrawable(d);
}

}
Activity:
package com.example.testclip;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.ScrollView;
public class TestClipMainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// setContentView(R.layout.activity_test_clip_main);
ScrollView sv = new ScrollView(this);
V v = new V(this);
sv.addView(v);
setContentView(sv);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.test_clip_main, menu);
return true;
}
}
This code produces the following output
02-15 10:47:54.011: D/OpenGLRenderer(833): Enabling debug mode 0
02-15 10:47:54.926: D/dalvikvm(833): threadid=1: still suspended after undo (sc=1 dc=1)

you must be doing something wrong, see this custom View:
class V extends View {
Rect clip = new Rect();
private int cnt = 20;
public V(Context context) {
super(context);
}
#Override
public boolean onTouchEvent(MotionEvent event) {
cnt++;
Log.d(TAG, "calling invalidate " + cnt);
invalidate(10, 10, cnt, cnt);
return false;
}
#Override
protected void onDraw(Canvas canvas) {
canvas.getClipBounds(clip);
Log.d(TAG, "onDraw clip " + clip);
}
}
UPDATE: custom view inside a ScrollView:
class V extends View {
Rect clip = new Rect();
public V(Context context) {
super(context);
int[] colors = {0xff000000, 0xffff0000, 0xffffffff};
Drawable d = new GradientDrawable(GradientDrawable.Orientation.TOP_BOTTOM, colors);
setBackgroundDrawable(d);
}
#Override
public boolean onTouchEvent(MotionEvent event) {
int x = (int) event.getX();
int y = (int) event.getY();
invalidate(x, y, x + 10, y + 10);
return true;
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int w = MeasureSpec.getSize(widthMeasureSpec);
setMeasuredDimension(w, w * 4);
}
#Override
protected void onDraw(Canvas canvas) {
canvas.getClipBounds(clip);
Log.d(TAG, "onDraw clip height: " + clip.height());
}
}
add this to onCreate:
ScrollView sv = new ScrollView(this);
V v = new V(this);
sv.addView(v);
setContentView(sv);

when move the image from bottom to up with animation,not getting the full image

when move the image from bottom to up with animation,not getting the full image,i am declaring imageview width wrap content.when i was moving the down its working perfectly,but when i image dragging up,the showing part comes with animation not getting the full image.

if you place image on button , Button will lose control so , you can give drawable (image) to button using background or drawable left or right top bottom ...or else you can implement on click listener even on image view..
Update..
<Button
android:id="#+id/btnFavorites"
android:layout_width="match_parent"
android:layout_height="45dip"
android:drawablePadding="10dp"
android:paddingLeft="10dp"
android:layout_marginTop="1dip"
android:gravity="left|center_vertical"
android:background="#242D41"
android:drawableLeft="#drawable/favorite_slide"
android:includeFontPadding="false"
android:text="#string/titleFavourites"
android:textColor="#ffffff"
android:textSize="15dip"
android:textStyle="bold" />
in the code i have given drawableleft, same yo can give for right top left and even padding also possible , and apply your logic for touch

Animate a view to slide in and slide out of the screen in android

Good day i have a view that is programmatically placed at the bottom left part of a SurfaceView and what i want is when a button is clicked, the view slides out of the screen and slides back in but nothing seems to happen in the animation. Here is my code, i will just put the relevant parts:
layout.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/my_Info"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#6444"
android:orientation="vertical"
android:visibility="visible" >
<TextView
android:id="#+id/name_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="16dp"
android:text="name" />
<TextView
android:id="#+id/medium_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="16dp"
android:text="med"/>
<TextView
android:id="#+id/dimensions_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="16dp"
android:text="dimen" />
</LinearLayout>
positioning the view:
RelativeLayout.param = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, 240);
param.leftMargin = 0;
inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.my_info, null);
mylayout = (LinearLayout)view.findViewById(R.id.gallery_Info_root_id); //what i want to animate
view.setLayoutParams(param);
param.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
param.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
view.getLayoutParams().width = 380;
RelativeLayout lContainerLayout = new RelativeLayout(VideoPlayback.this);
lContainerLayout.setLayoutParams(new RelativeLayout.LayoutParams( LayoutParams.MATCH_PARENT , LayoutParams.MATCH_PARENT ));
lContainerLayout.addView(view);
addContentView(lContainerLayout, new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
slide in and slide out animation:
private void slideInView(){
Animation slidein = new MyTranslateAnimation(mylayout, -mylayout.getWidth(), 0, 0, 0);
slidein.setDuration(animationDuration);
slidein.setInterpolator(interpolator);
mylayout.startAnimation(slidein);
}
private void slideOutView(){
Animation slidein = new MyTranslateAnimation(mylayout, 0, -mylayout.getWidth(), 0, 0);
slidein.setDuration(animationDuration);
slidein.setInterpolator(interpolator);
mylayout.startAnimation(slidein);
}
MyTranslateAnimation which i got from here
public class MyTranslateAnimation extends Animation {
private View view;
private final float fromX;
private final float toX;
private final float fromY;
private final float toY;
public MyTranslateAnimation(View v, float fromX, float toX, float fromY, float toY) {
view = v;
this.fromX = fromX;
this.toX = toX;
this.fromY = fromY;
this.toY = toY;
setDuration(500);
}
#Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
float x = (toX-fromX) * interpolatedTime + fromX;
float y = (toY - fromY) * interpolatedTime + fromY;
RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)view.getLayoutParams();
params.setMargins((int)x, (int)y, 0, 0);
view.requestLayout();
}
}
Please can anyone spot anything i am doing wrong? because i can't seem to see why i can't slide "mylayout" in and out. Thanks in advance.
