Create dynamic spinner

Question

I have an edit text in which I enter a number. I want according to the number entered in edit text to create spinners. For example if I enter 2 in edit text I have 2 spinners if 4 ==> 4 spinners.

Can any one post any example and please suggest which technique is better defining spinner data in Java or Xml?

Answer 1

used below code ...

public class MainActivity extends AppCompatActivity {
private EditText editText;
private Button mbtn;

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

private void initView() {
    editText = findViewById(R.id.amEtNumber);
    mbtn = findViewById(R.id.amBtnSave);
    LinearLayout main_layer = (LinearLayout) findViewById(R.id.main);

    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);

    LinearLayout layout = new LinearLayout(getApplicationContext());
    LinearLayout.LayoutParams params1 = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);

    layout.setOrientation(LinearLayout.VERTICAL);
    layout.setLayoutParams(params);
    mbtn.setOnClickListener(view -> {
        int times = Integer.parseInt(editText.getText().toString().trim());
        for (int i = 0; i < times; i++) {
            List<String> spinnerArray = new ArrayList<>();
            spinnerArray.add("Select Item");
            spinnerArray.add("Item1");
            Spinner spinner = new Spinner(this);
            ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>
                    (this, android.R.layout.simple_spinner_item,
                            spinnerArray); //selected item will look like a spinner set from XML
            spinnerArrayAdapter.setDropDownViewResource(android.R.layout
                    .simple_spinner_dropdown_item);
            spinner.setAdapter(spinnerArrayAdapter);

            layout.addView(spinner);
        }
        main_layer.addView(layout);

    });
}

}
