Putting a bitmap drawable into an array

So I have this image adapter class and a nav class. In the nav class I listen to the onclick of a button and then put the image into a URi. After that I convert it to a bitmap drawable. So my question is how can I put this drawable into my array in the imageadapter ?
Please note: I am passing the bitmap drawable from the nav.class to the image adapter.class.
nav class:
if(resultCode == RESULT_OK && requestCode == IMAGE_PICK){
imageuri = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageuri);
d = new BitmapDrawable(getResources(), bitmap);
System.out.println("----------------------------------------");
returndrawble();
} catch (IOException e) {
e.printStackTrace();
Toast.makeText(getApplicationContext(), "something went wrong", Toast.LENGTH_SHORT).show();
}
}
image adapter class:
public Drawable returndrawble(){
return d;
}
}
private Integer[] images = {
R.drawable.test, R.drawable.test2, R.drawable.test3, R.drawable.test4, R.drawable.test5, R.drawable.test6, R.drawable.test7, R.drawable.test8,

//nav nav = new nav();
//image = nav.d;

What I want to do is read the location that is being displayed when the user open's a page containing the above code, after reading the user's location I want to store those values in my database which I will later retrieve in another class.

Replacing the . with * didn't really work and from what Cao Minh Vu suggested that it might have a problem the mChatUser was pointing to a null value so I sorted that out and for may latitude and longitude is used:
String lat = String.ValueOf(latitude.getLatitude());
String long = String.valueOf(longitude.getLongitude());
Thanks to everyone who commented on my Post, I wasn't going to identify the problem because there's too many lines in my code it was hard to identify which one was giving me a problem

Show only numbers from text

I have a string that both the letter and the number.
As shown below:
I want to separate numbers from letters and When the user clicks the numbers
these numbers are displayed on the screen as buttons.
Such as following photos:
I have a activity that takes this string to another activity.
Basically what I should do? thanks.

textView.setText(strBox);

you should use Regex to exgtract Numbers from String
Pattern p = Pattern.compile("-?\\d+");
Matcher m = p.matcher("There are more than -2 and less than 12 numbers here");
while (m.find()) {
System.out.println(m.group());
}
on view click listener you can do this.
#Override
void onClick(View view){
String allTxt = editText.getText.toString()
Pattern p = Pattern.compile("-?\\d+");
Matcher m = p.matcher(allTxt);
while (m.find()) {
System.out.println(m.group());//here are the numbers then you can set it to another TextView
}
}

String str = "test-asdfdfg 455 yuoyr 4";
str = str.replaceAll("[^-?0-9]+", " ");
System.out.println(Arrays.asList(str.trim().split(" ")));
Output [455, 4] use this array to show chooser
