Android选择微调项进入警报对话框和文本按钮消失

Question

我有一个包含一系列元素的 ListView 。单击 ListView 的一项会显示一个自定义对话框。在自定义对话框中，我有一个布局:

• 旋转器
• 两个按钮(OK/ANNULLA)

这是正常情况:

当我选择微调器时，他会显示一个项目列表。

当我从微调器中选择一个项目时，按钮上的文本以这种方式消失:

ps:Android 6.0不会出现这种情况，低版本(比如5.0)会出现

代码:

public void showDialogTagAssociation (Activity activity, Handler handler,
                                     String msg, final MyOperator elemento, final BluetoothDevice device,
                                     final int position){

    mHandler = handler;

    //-----------------------------------------------------
    // DIALOG
    dialog = new Dialog(activity);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setCancelable(false);
    //-----------------------------------------------------

    //---------------------------------------------------------------------
    // LAYOUT
    dialog.setContentView(R.layout.alert_dialog_custom_tag);

    **// Spinner element
    spinner = (Spinner) dialog.findViewById(R.id.spinner);**

    // Spinner click listener
    **spinner.setOnItemSelectedListener(new OnSpinnerItemClicked());**
    //---------------------------------------------------------------------



    //----------------------------------------------------------------------
    // BUTTON OK
    dialogButtonOK = (Button) dialog.findViewById(R.id.acd_btn_ok);
    dialogButtonOK.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            Log.d(TAG, "Devo assegnare il tag al nome....");
            Log.d(TAG, "Nome: " +tmpNome+"\n" +
                "TAG: "+device.getName()+" - "+device.getAddress());

            dialog.dismiss();

        }
    });

    // BUTTON ANNULLA
    dialogButtonNO = (Button) dialog.findViewById(R.id.acd_btn_no);
    dialogButtonNO.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            dialog.dismiss();

        }
    });
    //----------------------------------------------------------------------

    dialog.show();

}


**private class OnSpinnerItemClicked implements android.widget.AdapterView.OnItemSelectedListener {**

    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {

        //NOME
        tmpNome = parent.getItemAtPosition(pos).toString();

    }

    @Override
    public void onNothingSelected(AdapterView parent) {
        // Do nothing.
    }
}

感谢以后的帮助

删除那段代码:

spinner.setOnItemSelectedListener(new OnSpinnerItemClicked());

你想要的东西仍然可以工作。
