我正在设计在线测验App。我设计了PlayQuiz.java文件如下：

public class PlayQuiz extends AppCompatActivity {

private RecyclerView recyclerView;

DataBaseHelper database;

private List quizList;

private QuizAdapter adapter;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_play_quiz);

Toolbar toolbar = findViewById(R.id.toolbar);

setSupportActionBar(toolbar);

recyclerView=(RecyclerView)findViewById(R.id.recycler_view_quiz_display);

database= new DataBaseHelper(PlayQuiz.this);

quizList= database.fillObjQuesList();

adapter=new QuizAdapter(quizList,getApplicationContext());

RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext());

recyclerView.setLayoutManager(mLayoutManager);

recyclerView.setItemAnimator(new DefaultItemAnimator());

recyclerView.setAdapter(adapter);

});

}

}

现在，这是我的QuizAdapter.java文件

public class QuizAdapter extends RecyclerView.Adapter{

private List questionList;

private Context context;

public QuizAdapter(List questionList, Context context) {

this.questionList = questionList;

this.context = context;

}

@NonNull

@Override

public CustomViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {

View itemView= LayoutInflater.from(parent.getContext()).inflate(R.layout.quiz_display_format,parent,false);

return new CustomViewHolder(itemView);

}

@Override

public void onBindViewHolder(@NonNull final CustomViewHolder holder, final int position) {

DmQuiz questionsList=questionList.get(position);

holder.tvquestion.getLayoutParams().width= LinearLayout.LayoutParams.WRAP_CONTENT;

holder.tvquestion.setText(questionsList.getQuestion());

holder.optA.setText(questionsList.getOpta());

holder.optB.setText(questionsList.getOptb());

holder.optC.setText(questionsList.getOptc());

holder.optD.setText(questionsList.getOptd());

holder.optA.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View view) {

holder.optA.setBackgroundColor(context.getResources().getColor(R.color.colorButton));

holder.optA.setBackgroundResource(R.drawable.button_border); holder.optB.setBackgroundResource(R.drawable.button_border_unselected); holder.optC.setBackgroundResource(R.drawable.button_border_unselected); holder.optD.setBackgroundResource(R.drawable.button_border_unselected);

}

});

holder.optB.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View view) {

holder.optA.setBackgroundResource(R.drawable.button_border_unselected);

holder.optB.setBackgroundResource(R.drawable.button_border);

holder.optC.setBackgroundResource(R.drawable.button_border_unselected);

holder.optD.setBackgroundResource(R.drawable.button_border_unselected);

}

});

holder.optC.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View view) {

holder.optA.setBackgroundResource(R.drawable.button_border_unselected);

holder.optB.setBackgroundResource(R.drawable.button_border_unselected);

holder.optC.setBackgroundResource(R.drawable.button_border);

holder.optD.setBackgroundResource(R.drawable.button_border_unselected);

}

});

holder.optD.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View view) {

holder.optA.setBackgroundResource(R.drawable.button_border_unselected);

holder.optB.setBackgroundResource(R.drawable.button_border_unselected);

holder.optC.setBackgroundResource(R.drawable.button_border_unselected);

holder.optD.setBackgroundResource(R.drawable.button_border);

}

});

holder.tvClear.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View view) {

holder.optA.setBackgroundResource(R.drawable.button_border_unselected);

holder.optB.setBackgroundResource(R.drawable.button_border_unselected);

holder.optC.setBackgroundResource(R.drawable.button_border_unselected);

holder.optD.setBackgroundResource(R.drawable.button_border_unselected);

}

});

}

@Override

public int getItemCount() {

return questionList.size();

}

public class CustomViewHolder extends RecyclerView.ViewHolder{

TextView tvquestion, tvClear;

Button optA,optB,optC,optD;

public CustomViewHolder(View itemView) {

super(itemView);

tvquestion=(TextView)itemView.findViewById(R.id.tvQuestion);

optA=(Button)itemView.findViewById(R.id.button1);

optB=(Button)itemView.findViewById(R.id.button2);

optC=(Button)itemView.findViewById(R.id.button3);

optD=(Button)itemView.findViewById(R.id.button4);

tvClear=(TextView)itemView.findViewById(R.id.tvClear);

}

}

public QuizAdapter(List questionList)

{

this.questionList=questionList;

}

public void setSearchOperation(List newList){

questionList= new ArrayList<>();

questionList.addAll(newList);

notifyDataSetChanged();

}

}

Recyclerview中的数据正在从SQLite数据库中显示。

现在我想处理/存储多个按钮上的点击并将其发送到远程MySql服务器。我很困惑，如何存储不同问题的回复？我应该使用ArrayList或其他东西，请帮助......
