Android 按id查找textview时遇到问题

我使用一个菜单充气器，在每一行我给textview和seekbar一个I的id（我使用for循环给它们一个id）。当我得到seekbar的id并且我想在textview中插入文本时。我遇到的问题是如何在textview中设置与seekbar值相同的文本

public static void setNewTipAmount(SeekBar barChanged, double amountForTip) {

 int getID = barChanged.getId(); //get seekbar id


    TextView textView = tipPerPerson.findViewById(getID);// get the textview with same id
            textView.setText("Hello");

}

}

下面是我如何分配Id的代码

        for (int i = 0; i < InBetweenUIAndBusinessLogic.getGuests(); i++) {
        View v = in.inflate(R.layout.row_per_person, table, false);
        double tipPerIndividual = (Math.round(InBetweenUIAndBusinessLogic
                .getTipPerPerson() * 100.0) / 100.0);
        String tip = Double.toString(tipPerIndividual);
        tipPerPerson = (TextView) v.findViewById(R.id.tipPerPerson);
        tipPerPerson.setId(i);
        tipPerPerson.setText(tip);
        rows.add(tipPerPerson);
        percentageTip = (SeekBar) v.findViewById(R.id.seekBar1);
        percentageTip.setOnSeekBarChangeListener(new myListener());
        double guests = InBetweenUIAndBusinessLogic.getGuests();
        percentageTip.setProgress((int) (100 / guests));
        percentageTip.setId(i);
        table.addView(v);
        bars.add(percentageTip);

    }

for（int i=0；i

我建议在

TextView

id和

Seekbar

id之间创建一个简单的映射。这样每个id都会不同，您仍然可以获得相应的项目id。以下是我的解决方案：

mGuestCount = InBetweenUIAndBusinessLogic.getGuests();

for (int i = 0; i < InBetweenUIAndBusinessLogic.getGuests(); i++) {
    View v = in.inflate(R.layout.row_per_person, table, false);
    double tipPerIndividual = (Math.round(InBetweenUIAndBusinessLogic
        .getTipPerPerson() * 100.0) / 100.0);
    String tip = Double.toString(tipPerIndividual);
    tipPerPerson = (TextView) v.findViewById(R.id.tipPerPerson);
    tipPerPerson.setId(i);
    tipPerPerson.setText(tip);
    rows.add(tipPerPerson);
    percentageTip = (SeekBar) v.findViewById(R.id.seekBar1);
    percentageTip.setOnSeekBarChangeListener(new myListener());
    double guests = InBetweenUIAndBusinessLogic.getGuests();
    percentageTip.setProgress((int) (100 / guests));
    percentageTip.setId(i + mGuestCount);
    table.addView(v);
    bars.add(percentageTip);
}

您能否发布代码，说明如何分配ID并将其添加到布局中。除非确定视图层次结构，否则应保持ID不同。我可以看看你的观点，给你一个可能的解决方案

public static void setNewTipAmount(SeekBar barChanged, double amountForTip) {
    int getID = barChanged.getId(); //get seekbar id

    TextView textView = tipPerPerson.findViewById(getID - mGuestCount);// get the textview with corresponding id
    textView.setText("Hello");
}
