</RelativeLayout>

它不打印任何东西。布局：

好的，我的旋转器代码看看它

final List<governatemodel> Go_data =  governat_data[0].getAllGovernante();
        final String[] governate_final_data = new String[Go_data.size()];
        for (int i = 0 ; i<Go_data.size() ; i++)
        {
            governate_final_data[i] = Go_data.get(i).getName();
        }
          final ArrayAdapter<CharSequence> langAdapter2 = new ArrayAdapter<CharSequence>(IntoductionActivity.this, R.layout.spinner_text, governate_final_data );
        langAdapter2.setDropDownViewResource(R.layout.simple_spinner_dropdown);
        governate_Spinner.setAdapter(langAdapter2);
        governate_Spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

                if (position != 0)
                {
                    governate_id_value = Go_data.get(position).getId();
                    String xx = Go_data.get(position).getName()+" ID is " + Go_data.get(position).getId();
                    Toast.makeText(IntoductionActivity.this, xx, Toast.LENGTH_SHORT).show();
                }
                else
                {
                    governate_id_value = 0;
                }
            }

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

            }
        });
