Question

#include <stdio.h>
#include <stdlib.h>

struct fl{    
  char sub[3] = {"Math","Science","ICT"};    
};

int main()
{    
    int i;

    struct fl floatp;

    for (i = 0; i < 3; ++i){    
        printf (" %s",floatp.sub[i]);    
    }

    return 0;
}

我收到此错误“struct fl在第11行没有名为sub的成员”。但我确实有一个名为'sub'的成员。我做错了什么？

你想要这个：

        btnDialog = (Button) findViewById(R.id.btnDialog);
        btnDialog.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                StringBuffer responseText = new StringBuffer();
                AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(context);
                alertDialogBuilder.setTitle("Diet Product");
                responseText.append("הפריטים שנבחרו הם: \n");

                for(int i=0;i<modelList.size();i++){
                    Models models = modelList.get(i);
                    if(models.isSelected()){
                        responseText.append("\n" + models.getName()+ " : "+models.getProtein() +"\n");
                    }
                }

                alertDialogBuilder
                        .setMessage(responseText.append("\n"+"לחישוב ערכים לחץ המשך " +"\n"+"או חזור לעידכון פרטים"+ "\n"))
                        .setCancelable(false)
                        .setPositiveButton("המשך", new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int id) {
                                // if this button is clicked, close current activity
                                //MainActivity.this.finish();
                                Intent intent = new Intent(getApplicationContext(),ItemActivity.class);
                                intent.putExtra(models.getName(),"name");
                                startActivity(intent);
                            }
                        })
                        .setNegativeButton("חזור", new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int id) {

                                dialog.cancel();
                            }
                        });
                AlertDialog alertDialog = alertDialogBuilder.create();
                alertDialog.show();

Struct fl没有名为sub的成员
