获取TableRow标识

Question

我想在index中获得点击行的id或TableLayout。一些代码看起来：

final TableRow rows = new TableRow(this);
rows.setClickable(true);

单击按钮的操作，向TableLayout添加行

TableRow row = new TableRow(getApplicationContext());
row.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.WRAP_CONTENT));
row.setTag(String.valueOf(queue_number));
row.setClickable(true);

if (queue_number % 2 == 0) {
row.setBackgroundColor(getResources().getColor(R.color.blue_grey));
} else {
row.setBackgroundColor(getResources().getColor(R.color.white));
}

TextView row_queue = new TextView(Satish.this);
row_queue.setText(String.valueOf(queue_number));
row_queue.setPadding(6, 6, 0, 6);

TextView row_product_name = new TextView(Satish.this);
row_product_name.setText(product_name.getText().toString());
row_product_name.setPadding(0, 6, 0, 6);

TextView row_unit_of_measurement = new TextView(Satish.this);
row_unit_of_measurement.setText(unit_of_measurement.getText().toString());
row_unit_of_measurement.setPadding(0, 6, 0, 6);

TextView row_price = new TextView(Satish.this);
row_price.setText(price.getText().toString());
row_price.setPadding(0, 6, 0, 6);

TextView row_sum = new TextView(Satish.this);
row_sum.setText(sum.getText().toString());
row_sum.setPadding(0, 6, 0, 6);

row.addView(row_queue);
row.addView(row_product_name);
row.addView(row_unit_of_measurement);
row.addView(row_price);
row.addView(row_sum);
root_table.addView(row);
queue_number++;

在rows的点击事件中看起来：

rows.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                  Toast.makeText(getApplicationContext(), String.valueOf(v.getId()), LENGTH_LONG).show();
//                client_name.setText(String.valueOf(rows.getChildAt(1)));
//                   TableRow t = (TableRow) v.getParent();
//                Toast.makeText(getApplicationContext(), String.valueOf(t.getId()), LENGTH_LONG).show();
//                for (int id = 0; id < root_table.getChildCount(); id++) {
//                    if (v.getId() == id) {
//                        Toast.makeText(Satish.this, String.valueOf(r[0].getId()), LENGTH_LONG).show();
//                    }
//                }
            }
        });

但是这个事件只返回没有。我不知道我的代码中有什么问题。我看不出错误。

任何有用的评论/回答都表示赞赏。

P.S我在互联网上搜索过这个问题，但找不到解决这个问题的正确方法。但是，也许这个问题可能重复。

修改

我可以将rows替换为row。如果我这样做，那么只有一个 TableRow元素。所以代码看起来像：

final TableRow row = new TableRow(getApplicationContext());
row.setClickable(true);

单击按钮的操作，向TableLayout添加行

row.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.WRAP_CONTENT));
row.setTag(String.valueOf(queue_number));
row.setClickable(true);

if (queue_number % 2 == 0) {
row.setBackgroundColor(getResources().getColor(R.color.blue_grey));
} else {
row.setBackgroundColor(getResources().getColor(R.color.white));
}

TextView row_queue = new TextView(Satish.this);
row_queue.setText(String.valueOf(queue_number));
row_queue.setPadding(6, 6, 0, 6);

TextView row_product_name = new TextView(Satish.this);
row_product_name.setText(product_name.getText().toString());
row_product_name.setPadding(0, 6, 0, 6);

TextView row_unit_of_measurement = new TextView(Satish.this);
row_unit_of_measurement.setText(unit_of_measurement.getText().toString());
row_unit_of_measurement.setPadding(0, 6, 0, 6);

TextView row_price = new TextView(Satish.this);
row_price.setText(price.getText().toString());
row_price.setPadding(0, 6, 0, 6);

TextView row_sum = new TextView(Satish.this);
row_sum.setText(sum.getText().toString());
row_sum.setPadding(0, 6, 0, 6);

row.addView(row_queue);
row.addView(row_product_name);
row.addView(row_unit_of_measurement);
row.addView(row_price);
row.addView(row_sum);
root_table.addView(row);
queue_number++;

在这种情况下，TableLayout会出现一些设计问题。

Answer 1

我为我的问题找到了最佳解决方案。

我将以下行从 onCreate()内的移至按钮点击事件：

final TableRow row = new TableRow(getApplicationContext());
row.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.WRAP_CONTENT));
row.setId(Integer.valueOf(String.valueOf(queue_number)));
row.setClickable(true);

if (queue_number % 2 == 0) {
    row.setBackgroundColor(getResources().getColor(R.color.blue_grey));
} else {
    row.setBackgroundColor(getResources().getColor(R.color.white));
}

TextView row_queue = new TextView(Satish.this);
row_queue.setText(String.valueOf(queue_number));
row_queue.setPadding(6, 6, 0, 6);

TextView row_product_name = new TextView(Satish.this);
row_product_name.setText(product_name.getText().toString());
row_product_name.setPadding(0, 6, 0, 6);

TextView row_unit_of_measurement = new TextView(Satish.this);
row_unit_of_measurement.setText(unit_of_measurement.getText().toString());
row_unit_of_measurement.setPadding(0, 6, 0, 6);

TextView row_price = new TextView(Satish.this);
row_price.setText(price.getText().toString());
row_price.setPadding(0, 6, 0, 6);

TextView row_sum = new TextView(Satish.this);
row_sum.setText(sum.getText().toString());
row_sum.setPadding(0, 6, 0, 6);

row.addView(row_queue);
row.addView(row_product_name);
row.addView(row_unit_of_measurement);
row.addView(row_price);
row.addView(row_sum);

root_table.addView(row/*, queue_number*/);

// set onClickListener at runtime. This is working well for me.
root_table.getChildAt(queue_number).setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        TableRow tr = (TableRow) v;
        TextView num, p_n, u_o_m, p, s;
//        num = (TextView) tr.getChildAt(0);
        p_n = (TextView) tr.getChildAt(1);
        u_o_m = (TextView) tr.getChildAt(2);
        p = (TextView) tr.getChildAt(3);
        s = (TextView) tr.getChildAt(4);
//        row_id = Integer.getInteger(num.getText().toString());
        product_name.setText(p_n.getText().toString());
        unit_of_measurement.setText(u_o_m.getText().toString());
        price.setText(p.getText().toString());
        sum.setText(s.getText().toString());
    }
});

queue_number++;
