Forward Android spinner value

String[] items = { "less than 4 months", "4 to 6 months", "7 to 12 months", "neutralized grave", "General grave", "Exercise grave", "Roh grave", "Obese grave"};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);




    // a code used to write a spinner //
    Spinner spinner = findViewById (R.id.spinner); // Spinner initialization
    ArrayAdapter<String>adapter=newArrayAdapter<String>( // Let's write the array as a string type.
            this, android.R.layout.simple_spinner_item, items);
    adapter.setDropDownViewResource(
            android.R.layout.simple_spinner_dropdown_item);



    spinner.setAdapter(adapter);

    spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {

        }    // Adapter Method Declaration for Spinner Writing
    });

    Button button = findViewById(R.id.button);

    if (items.equals (the "old tomb")
        if ( button != null ) {
            button.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                        showToast("g");

                }
            });
        }

    }



}

Create public void showToast(String data) { //Toast Message Method
    Toast.makeText(this, data, Toast.LENGTH_LONG).show();
}

}

I created a spinner and created an array as shown above. For example, when I choose "Roh Myo" for spinners, I want to have a random toast message That's not gonna work. What do I do?

if (items).equals (the "old tomb")

1 When the condition of the spinner becomes "old seedling".

Button.setOnClickListener(newView).OnClickListener() {

I will register a click listener at button 2.

I think that's what you've been working on..

Let's think differently.

First, register 'Button Click Listener' () {
    Why don't you set the value stored in the spinner to be read?
}

Here's what I think.

if (button!=null) {
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String selectedItemName = spinner.getSelectedItem().toString();
            if (selectedItemName.equals ("old seed") {
                showToast("g");
            } else if (selectedItemName.equals ("obesity") {
                showToast("h");
            }
        }
    });
}

1st -> To achieve 2nd order in the first place

The value of the spinner is also the same as the button

A device is required to monitor operations with varying status (although it does exist). https://mailmail.tistory.com/16 See

And simply by putting an if statement at the time of onCreate, it doesn't detect any state value of any object.

Then you don't need a button click listener.

if (Button.onClick) {}

It would have been the same form.

/** First, prepare a device to detect and condition it **/

Please think about why the event listener exists and how it works.
