How to add progress bar to an Imageview programmatically in android?

I have a class that extends Imageview. I need to add a progress bar to that ImageView programmatically.
This is my code:
public void viewPopup() {
DisplayMetrics metrics = new DisplayMetrics();
((Activity) getContext()).getWindowManager().getDefaultDisplay().getMetrics(metrics);
int width = metrics.widthPixels;
int height = metrics.heightPixels;
if(isFullScreen()) {
popupWindow = new PopupWindow(layout, (width), (height), true);
}else {
if (windowHeight != 0 || windowWidth != 0) {
width = windowWidth;
height = windowHeight;
popupWindow = new PopupWindow(layout, (width), (height), true);
} else {
popupWindow = new PopupWindow(layout, (int) (width * .8), (int) (height * .6), true);
}
}
popupWindow.showAtLocation(layout, Gravity.CENTER, 0, 0);
ImageView closeIcon = (ImageView) layout.findViewById(R.id.closeBtn);
if (isHideCloseIcon()) {
closeIcon.setVisibility(View.GONE);
}
closeIcon.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
popupWindow.dismiss();
}
});
if (isImageOnClickClose()) {
imageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
popupWindow.dismiss();
}
});
}
dimBehind(popupWindow);
}
I need to initialize the progress bar after the metrics and it should disappear after the image loads (i.e inside the popup window).
I tried this for initialization :
progressBar = new ProgressBar(activity, null, android.R.attr.progressBarStyleHorizontal);
But I don't know how to proceed after this.

How to center PopupWindow?

I created an Activity in which i add a button that throws a popup when is clicked. Here is the code of showPopup() method:
private void showPopup() {
LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.popup_layout, (ViewGroup) findViewById(R.id.popup_element), false);
final PopupWindow pwindo = new PopupWindow(layout, LayoutParams.WRAP_CONTENT, LayoutParams.MATCH_PARENT, true);
Button btnAgree = (Button) layout.findViewById(R.id.ok);
btnAgree.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
pwindo.dismiss();
}
});
pwindo.showAtLocation(layout, Gravity.CENTER, 0, 0);
}
}
I would center it both vertically and orizzontally. I tried several ways that i see here on SO but none worked. Why i always get the popup window at the top of the screen?

you can use setHorizontalOffset:
ListPopupWindow popupWindow = new ListPopupWindow(this);
// Position
popupWindow.setAnchorView(btn);
popupWindow.setPromptPosition (ListPopupWindow.POSITION_PROMPT_ABOVE);
popupWindow.setHorizontalOffset((btn.layoutParams.width - popupWindow.getWidth())/2);

this code will show perfect popup in center of you specific view
// click event of specific view
#Override
public void onClick(View v) {
super.onClick(v);
if (v == lin_filterActionbar) {
PopupWindow popupwindow_obj; // create object
popupwindow_obj = dialog_AllergiesSelect(RR_HomeActivity.this,lin_filterActionbar);
popupwindow_obj.showAsDropDown(lin_filterActionbar);
}
}
private PopupWindow dialog_AllergiesSelect(Context context,LinearLayout lin) {
final PopupWindow dialog_AllergiesSelect = new PopupWindow(this);
View v = View.inflate(context, R.layout.dialog_filter_actionbar, null);
dialog_AllergiesSelect.setContentView(v);
dialog_AllergiesSelect.setWidth(WindowManager.LayoutParams.WRAP_CONTENT);
dialog_AllergiesSelect.setHeight(WindowManager.LayoutParams.WRAP_CONTENT);
dialog_AllergiesSelect.setFocusable(true);
// TextView lis_testSelection = (TextView) v.findViewById(R.id.dialogfilter_txt_filter);
// LinearLayout.LayoutParams lin_laLayoutParams = new LinearLayout.LayoutParams((int) (sunApplication.getDeviceWidth() - (sunApplication.getDeviceScale() * dialog_width_dvide_allerges_spinner_width)), (int) (sunApplication.getDeviceHeight() - (sunApplication.getDeviceScale() * dialog_width_dvide_allerges_height)));
// lis_testSelection.setLayoutParams(lin_laLayoutParams);
// Some offset to align the popup a bit to the right, and a bit down, relative to button's position.
int OFFSET_X = 0;
int OFFSET_Y = 0;
// Clear the default translucent background
dialog_AllergiesSelect.setBackgroundDrawable(new BitmapDrawable());
// Displaying the popup at the specified location, + offsets.
//dialog_AllergiesSelect.showAtLocation(v, Gravity.C, p.x + OFFSET_X, p.y + OFFSET_Y);
Rect location = locateView(lin);
dialog_AllergiesSelect.showAtLocation(v, Gravity.TOP|Gravity.CENTER, 0, location.bottom);
// Getting a reference to Close button, and close the popup when clicked.
return dialog_AllergiesSelect;
}
public static Rect locateView(View v)
{
int[] loc_int = new int[2];
if (v == null) return null;
try
{
v.getLocationOnScreen(loc_int);
} catch (NullPointerException npe)
{
//Happens when the view doesn't exist on screen anymore.
return null;
}
Rect location = new Rect();
location.left = loc_int[0];
location.top = loc_int[1];
location.right = location.left + v.getWidth();
location.bottom = location.top + v.getHeight();
return location;
}

Popup showAtLocation is not working

I'm using pop-window to show some text-view while clicking the edit-text . but pop-window is not showing at particular location ,it always showing at left top corner , here is my code ,what is wrong in that
private void showPopup(Context context,final LinearLayout Parent) {
LayoutInflater layoutInflater = (LayoutInflater)context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
layout = layoutInflater.inflate(R.layout.popup,MainActivity.parent,true);
// Creating the PopupWindow
final PopupWindow popupWindow = new PopupWindow(
layout,700,700);
popupWindow.setContentView(layout);
popupWindow.setHeight(500);
new Runnable(){
#Override
public void run() {
popupWindow.showAtLocation(layout, Gravity.CENTER,300,150);
}
};
}

Try Following Code:
public static Rect locateView(View v)
{
int[] loc_int = new int[2];
if (v == null) return null;
try
{
v.getLocationOnScreen(loc_int);
} catch (NullPointerException e)
{
//Happens when the view doesn't exist on screen anymore.
return null;
}
Rect location = new Rect();
location.left = loc_int[0];
location.top = loc_int[1];
location.right = location.left + v.getWidth();
location.bottom = location.top + v.getHeight();
return location;
}
And then use
popup.showAtLocation(parent, Gravity.TOP|Gravity.LEFT, location.left, location.bottom);
Hope it helps...

Setting Window Dim only working in onCreate()

I have a little problem with my Window dimming.
Basically, I want to set the dimAmount of my Activity to zero as soon as I swipe it into one direction.
Please be aware that my Activity is displayed as a dialog, and can be swiped to the left or right. This works perfectly fine. But the setWindowDim() method has no effect when called after swipe.
If i call the setWindowDim inside my onCreate method, it works perfectly fine.
I have no idea why it doesnt work anywhere else.
public class FinishDialog extends Activity {
private FrameLayout frame = null;
private GestureDetector gd = null;
private int displaywidth = 0;
private int original_x = 0;
private int dialog_width = 0;
private final int POS_LEFT = -1;
private final int POS_MID = 0;
private final int POS_RIGHT = 1;
/** the dialogs current position, POS_MID on startup */
private int current_pos = POS_MID;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
//this.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
frame = new FrameLayout(this);
gd = new GestureDetector(this, new TouchManager(this));
// fill the challenge layout into the framelayout
frame.addView(LayoutInflater.from(getBaseContext()).inflate(R.layout.finishdialog, null));
setContentView(frame);
FrameLayout.LayoutParams lp = (FrameLayout.LayoutParams) frame.getLayoutParams();
GameLogic g = new GameLogic();
displaywidth = g.getDisplayWidth(this);
lp.width = displaywidth - displaywidth / 6;
lp.gravity = Gravity.CENTER_HORIZONTAL | Gravity.CENTER_VERTICAL;
LinearLayout llFinish = (LinearLayout) findViewById(R.id.llFinishDialog);
LinearLayout.LayoutParams lpLL = (LinearLayout.LayoutParams) llFinish.getLayoutParams();
lp.height = lpLL.height;
frame.setLayoutParams(lp);
// setWindowDim(0.0f); ---> if i set the dim here, it works perfectly fine
original_x = (int) frame.getX();
dialog_width = lp.width;
}
private void setWindowDim(float dim) {
Log.i("FinishDialog", "Setting window dim to " + dim + ".");
WindowManager.LayoutParams lpWin = getWindow().getAttributes();
lpWin.dimAmount = dim;
getWindow().setAttributes(lpWin);
}
/**

break;

current_pos = POS_MID;
setWindowDim(0.9f); // here setting the dim has no effect
}
}
Log.i("Challenge", "Moving dialog to the left.");
break;
}
}
#Override
public boolean onTouchEvent(MotionEvent event) {
return gd.onTouchEvent(event);
}
private void swipeDialog(int time, View framelayout, int fromDeltaX, int toDeltaX, int fromDeltaY, int toDeltaY) {
Log.i("FinishDialog", "Dialog swiped.");
TranslateAnimation trans = new TranslateAnimation(fromDeltaX, toDeltaX,
fromDeltaY, toDeltaY);
trans.setFillAfter(true);
trans.setFillEnabled(true);
trans.setDuration(time);
framelayout.startAnimation(trans);
}
}

Starting this activity right after I change the Window dim finally did the job.
Unfortunately, now the Screen flashes pretty "ugly" when the RefreshActivity gets started, does anyone have a solution for that?
import android.app.Activity;
import android.os.Bundle;
public class RefreshActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
finish();
}
}
