Question

我想只在myast里面显示我的Toast里面的字符串编号，但是我无法找到那个东西。欢迎任何帮助！

    if(cursor.moveToFirst())
    {
        do
        {
            String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));

            if(Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0)
            {
                Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",new String[]{ id }, null);
                while (pCur.moveToNext())
                {
                    String name = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
                    String number = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                    list.add(name + "\n" + number);
                    break;
                }

                pCur.close();
            }

        } while (cursor.moveToNext()) ;

    }

适配器不重要的东西

    spinnerClickListener();


}

用于图像按钮的onclick方法，以在吐司中显示所选的联系电话号码。

public void spinnerClickListener(){
    //spinner item button onclick listener

    callBTN = (ImageButton)findViewById(R.id.call);
    mySpinner = (Spinner)findViewById(R.id.contacts);

    callBTN.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Toast.makeText(MainActivity.this, "Selected number :" + "\n" + mySpinner.getSelectedItem(), Toast.LENGTH_LONG).show();
        }
    });

}

提前感谢！

你应该使用这个

mySpinner.getSelectedItem().toString()

而不是

mySpinner.getSelectedItem()

android java get spinner选中的字符串值
