我基于方法中发送的 JSON 对象构建了一个 UI。每次运行该方法时,都会在 UI 中添加一个新行。我需要我的 chartsButtonListener 才能访问 JSONObject question

public void buildQuestions(JSONObject question) throws JSONException {
    LayoutInflater inflater = (LayoutInflater) getActivity().
    getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    questionContainer = (TableLayout) mainLayout.findViewById(R.id.questionContainer);

    View questionBox = inflater.inflate(R.layout.question, null);
    questionBox.setId(Integer.parseInt(question.getString("id")));
    TextView title = (TextView) questionBox.findViewById(R.id.questionTextView);
    title.setText(question.getString("title"));

    //omitted code for verbosity

    Button chartsButton = (Button) questionBox.findViewById(R.id.chartsButton);

    Button submitButton = (Button) questionBox.findViewById(R.id.submitButton);
    chartsButton.setOnClickListener(chartsListener);
    submitButton.setOnClickListener(submitListener);

    TableRow tr = (TableRow) questionBox;
    TableLayout.LayoutParams trParams = new TableLayout.LayoutParams(
    TableLayout.LayoutParams.MATCH_PARENT,
    TableLayout.LayoutParams.MATCH_PARENT);
    trParams.setMargins(leftMargin, topMargin, rightMargin, bottomMargin);
    tr.setLayoutParams(trParams);   
    LinearLayout progressRow = (LinearLayout) mainLayout.findViewById(R.id.progressRow);
    progressRow.setVisibility(View.GONE);
    questionContainer.addView(tr);
}

public OnClickListener chartsListener = new OnClickListener() {
    public void onClick(View v) {
        Intent chart = new Intent();
        chart.setClass(getActivity(), Chart.class);
        Log.v("", v.getParent().getClass().toString());//returns the TableRow
        startActivity(chart);
    }   
};

我对 put extra 很熟悉,但最好是直接将问题对象直接传递给听众,这样我就可以将其转发给 Intent。有什么建议么?

您可以使用 View.setTag(Object) 将任意对象关联到视图。

chartButton.setTag(问题);

在您的 onClick 中,您可以执行以下操作: Question q = (Question) v.getTag();
