如何以编程方式在给定位置Android更改微调器项目名称

Question

I would like to programmatically change a name of one of my spinner item but I am not sure how I can do this.

For example given the code below

Spinner spinner = (Spinner) MenuItemCompat.getActionView(item);

ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
         R.array.spinner_list_item_array,android.R.layout.simple_spinner_item);

adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

spinner.setAdapter(adapter);

I would like to

Change spinner ITEM name at position 1 to "NEW TEXT"

Answer 1

You should change the data in R.array.spinner_list_item_array .

After you have changed the data you will need to then call adapter.notifyDataSetChanged() and then adapter.setAdapter(adapter) .

Answer 2

 CharSequence[] fiilliste = getResources().getStringArray(R.array.spinner_list_item_array);
        ArrayAdapter<CharSequence> adapter =
                new ArrayAdapter<CharSequence>(this, android.R.layout.simple_spinner_dropdown_item, fiilliste);
        spinner.setAdapter(adapter);
        fiilliste[1] = "NEW TEXT";
        adapter.notifyDataSetChanged();
