Hi Jay McGavren, welcome to Ranch !

how this for loop affect to count variable?

count will be increased if variable i is less or equal to 10.  

Parents please be aware and very cautious of what your child watches on YouTube and KIDS YOUTUBE. There is a thing called ‘Momo’ that’s instructing kids to kill themselves, turn stoves on while everyone is sleep and even threatening to kill the children if they tell their parents!!!

The reason why onActivityResult not getting called is because the bitmap parameter is too large for Bundle.

My flow of activity is like this.

In Fragment  A, it allow user to capture image, and the image will be displayed on Activity B for user to do some editing.

Fragment A
   mImageListAdapter.mAddImageClickListener = object : ImageListAdapter.AddImageClickListener {                override fun addImageClicked() {                    val options = arrayOf<CharSequence>("Take Photo", "Choose From Gallery", "Cancel")                    val builder = android.support.v7.app.AlertDialog.Builder(activity)                    builder.setTitle("Select Option")                    builder.setItems(options) { dialog, item ->                        if (options[item] == "Take Photo") {                            dialog.dismiss()                            val intent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)                            startActivityForResult(intent, CAMERA_CAPTURE)                        }                    }                    builder.show()                }            }    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {            super.onActivityResult(requestCode, resultCode, data)            var bitmap: Bitmap? = null            if (requestCode == CAMERA_CAPTURE && resultCode == Activity.RESULT_OK) {                val extras = data?.extras                if (extras != null) {                    bitmap = extras.get("data") as Bitmap                    val intent = Intent(activity, ActivityB::class.java)                    intent.putExtra("bitmap", bitmap)                    startActivityForResult(intent, 12)                }            } else if (requestCode == 12 && resultCode == Activity.RESULT_OK) {                longToast("It get result from Activity B")            } else {                longToast("Nothing")            }        }
In Activity B,once the done button is clicked, the edited image suppose to be return to Fragment A, where I expect "It get result from Activity B" will be displayed, but nothing get displayed!

Activity B  doneBtn.setOnClickListener {                image.buildDrawingCache()                val bitmap = image.getDrawingCache()                val resultIntent = Intent()                resultIntent.putExtra("bitmap", bitmap)                setResult(Activity.RESULT_OK, resultIntent)                finish()            }

Hi Dawn & David Griffiths, welcome to Ranch

By using below code, I expect the output will be A,B,C, but I get word1,word2 and word3.
Is there any way to get the output printed as A,B,C by using for loop?

public class JavaApplication3 {    public static void main(String[] args) {                String word1 = "A";        String word2 = "B";        String word3 = "C";        for (int i = 1; i <= 3; i++) {            System.out.println("word"+i);        }    } }

Here my answer
spinnerStatus.setSelection(getIndex(spinnerStatus, "Two")); private fun getIndex(spinner: Spinner, myString: String): Int {        var index = 0                for (i in 0 until spinner.adapter.count) {            if (spinner.getItemAtPosition(i) == myString) {                index = i            }        }        return index    }

How do we know value Two is belongs to which position?

Lets said I have two activities which named Activity A and Activity B.

In Activity B, it has a spinner with three items, One,Two and Three.

I'm passing value Two from Activity A to Activity B using intent. How can I set the spinner to display Two according to the value I pass from activity A in activity B ?

 

The xml image you posted is not enough for us to check.Please post the full xml.

For the second question:

2. How do i fix the emulator, it is not showing me the app, only the regular phone functions?

Wonder have you created an AVD ?

If you want online, try explore on 000webhost. It allows you to put PHP script inside and the database is MySQL.

1. Move setContentView to the line after super.onCreate(...)'
2. Make sure you have edittext and textview in activity_main

You get download WampServer or Xampp by free.
