如何从自定义微调器中获取 selected 文本？

我的微调器包含名字 Raju 和 Rani；如果我 select "Raju," 那么 "Raju" 必须打印，如果我 select "Rani," 那么 "Rani" 必须打印。

spinnerName = (Spinner)m_view.findViewById(R.id.spinner_name);
ArrayAdapter<String> adapterName = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_spinner_dropdown_item) {

                @Override
                public View getView(int position, View convertView, ViewGroup parent) {

                    View v = super.getView(position, convertView, parent);
                    if (position == getCount()) {
                        ((TextView)v.findViewById(android.R.id.text1)).setText("");
                        ((TextView)v.findViewById(android.R.id.text1)).setHint(getItem(getCount()));



                          String  spinnertext = spinnerCity.getSelectedItem().toString();   
                        System.out.println("spinner" +spinnertext);


                    }

                    return v;
                }       

                @Override
                public int getCount() {
                    return super.getCount()-1; // you dont display last item. It is used as hint.
                }

            };



            adapterCity.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
            adapterCity.add("Raju");
            adapterCity.add("Rani");             
            adapterCity.add("name"); //This is the text that will be displayed as hint.
                spinnerName.setAdapter(adapterName);
        spinnerName.setSelection(adapterName.getCount());

Answer 1

利用 setOnItemSelectedListener。它将return你选择的微调器

示例

spinner.setOnItemSelectedListener(this); 
... 
public void onItemSelected(AdapterView<?> parent, View view, int pos,long id) { 
Toast.makeText(parent.getContext(), "OnItemSelectedListener : " + parent.getItemAtPosition(pos).toString(), Toast.LENGTH_SHORT).show(); 
}

Answer 2

我认为您已经填充了微调器。现在编写此代码以从微调器

中获取选定的文本

spinnerName.setOnItemSelectedListener(new OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView<?> arg0, View arg1,
                    int arg2, long arg3) {
                // TODO Auto-generated method stub
                String text = spinnerName.getSelectedItem().toString();
            }
}

文本包含选定的文本.. 现在您可以将其用作您的逻辑。希望它有效...
