为什么信息无法在我的微调器中显示 [英] Why information unable to display in my spinner

问题描述

为什么我的代码无法显示微调器？我的textview工作正常，但微调器无法工作。我已经输入了数据库的信息



NearablesDemoActivity.java

Why is it my code is unable to display the spinner? My textview works fine but the spinner unable to work. I have already enter the information for the database

NearablesDemoActivity.java

private void displayCurrentNearableInfo() {

        stickerdb = new Database_sticker(this);
        dbRow = stickerdb.getResult(currentNearable.identifier);
        dbRow.getId();
        dbRow.getIdentifier();
        //dbRow.getSa();
        //dbRow.getCa();

        String desc = dbRow.getDesc().toString();
        String sa = dbRow.getSa().toString();
        String ca = dbRow.getCa().toString();
        String coo = dbRow.getCoo().toString();
        String sm = dbRow.getSm().toString();
        String price = dbRow.getPrice().toString();

        //Set the text to the TextView
        Desc.setText(desc);
        SA.setText(sa);
        CA.setText(ca);
        COO.setText(coo);
        SM.setText(sm);
        Price.setText(price);
    }

ListNearablesActivity.java

ListNearablesActivity.java

private AdapterView.OnItemClickListener createOnItemClickListener() {
       return new AdapterView.OnItemClickListener() {
           @Override
           public void onItemClick(AdapterView<?> parent, View view, final int position, long id) {
               if (getIntent().getStringExtra(EXTRAS_TARGET_ACTIVITY) != null){
                   try {
                       Class<?> clazz = Class.forName(getIntent().getStringExtra(EXTRAS_TARGET_ACTIVITY));
                       Intent intent = new Intent(ListNearablesActivity.this, clazz);
                       intent.putExtra(EXTRAS_NEARABLE, adapter.getItem(position));
                       startActivity(intent);
                   } //close for try
                   catch (ClassNotFoundException e) {
                       Log.e(TAG, "Finding class by name failed", e);
                   } //close for catch (ClassNotFoundException e)
               } //close for getintent.getStringExtra()
           } //close for public void onitemclick
       };   //close for return new adapterview
   }  //close for private adapter
