private void callPopup() {
LayoutInflater layoutInflater = (LayoutInflater)getBaseContext()
.getSystemService(LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate(R.layout.popup, null);
popupWindow=new PopupWindow(popupView,
LayoutParams.WRAP_CONTENT, LayoutParams.MATCH_PARENT,
true);
popupWindow.setTouchable(true);
popupWindow.setFocusable(true);
popupWindow.showAtLocation(popupView, Gravity.CENTER, 0, 0);
Name = (EditText) popupView.findViewById(R.id.edtimageName);
((Button) popupView.findViewById(R.id.saveBtn))
.setOnClickListener(new OnClickListener() {
@TargetApi(Build.VERSION_CODES.GINGERBREAD)
public void onClick(View arg0) {
Toast.makeText(getApplicationContext(),
Name.getText().toString(),Toast.LENGTH_LONG).show();
popupWindow.dismiss();
}
});
((Button) popupView.findViewById(R.id.cancelbtutton))
