java - 填充微调器

Question

我有 4 个复选框，当我选中时，勾选一个、两个或多个。我想用值填充我的微调器，如果选中复选框 1，则填充 1-5；如果选中复选框 2，则填充 6-10，等等。我这里有这个逻辑。

public void populateSpinnerToothNumber() {
    if (cbQuadrant1.isChecked()) {
        ArrayList<String> toothNumber = new ArrayList<>();
        toothNumber.add("1");
        toothNumber.add("2");
        toothNumber.add("3");
        toothNumber.add("4");
        toothNumber.add("5");

        ArrayAdapter<String> stringArrayAdapter = new ArrayAdapter<>(this, R.layout.support_simple_spinner_dropdown_item, toothNumber);
        spinnerToothNumber.setAdapter(stringArrayAdapter);
    } else if (cbQuadrant2.isChecked()) {

    } else if (cbQuadrant3.isChecked()) {

    } else if (cbQuadrant4.isChecked()) {

    } else if (cbQuadrant1.isChecked() && cbQuadrant2.isChecked()) {
        ArrayList<String> toothNumber = new ArrayList<>();
        toothNumber.add("1");
        toothNumber.add("2");
        toothNumber.add("3");
        toothNumber.add("4");
        toothNumber.add("5");
        toothNumber.add("6");
        toothNumber.add("7");
        toothNumber.add("8");
        toothNumber.add("9");
        toothNumber.add("10");

        ArrayAdapter<String> stringArrayAdapter = new ArrayAdapter<>(this, R.layout.support_simple_spinner_dropdown_item, toothNumber);
        spinnerToothNumber.setAdapter(stringArrayAdapter);
    }
}

如何改进逻辑？

更新

public void populateSpinnerToothNumber() {
    final ArrayList<String> toothNumber = new ArrayList<>();

    cbQuadrant1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
            for (int x = 1; x <= 5; x++) {
                toothNumber.add(String.valueOf(x));
            }
        }
    });

    cbQuadrant2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
            for (int x = 6; x <= 10; x++) {
                toothNumber.add(String.valueOf(x));
            }
        }
    });

    cbQuadrant3.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
            for (int x = 11; x <= 15; x++) {
                toothNumber.add(String.valueOf(x));
            }
        }
    });

    cbQuadrant4.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
            for (int x = 16; x <= 20; x++) {
                toothNumber.add(String.valueOf(x));
            }
        }
    });

    ArrayAdapter<String> stringArrayAdapter = new ArrayAdapter<String>(this, R.layout.support_simple_spinner_dropdown_item, toothNumber);
    spinnerToothNumber.setAdapter(stringArrayAdapter);
}

这解决了问题:) 使用 checkbox.setOnCheckedChangeListener 管理它 感谢您的帮助! :)

添加到@Nilesh Rathod。您可以使用名为 populateSpinner (int bgCount, int Endcount) 的方法，该方法获取从开始范围到结束所需的 dentry 数量。

private void populateSpinner (int bgCount, int Endcount) {
    ArrayList<String> toothNumber = new ArrayList<>();
    for (int i = bgCount; i < Endcount; i++) {
          toothNumber.add(i);
     }
    ArrayAdapter<String> stringArrayAdapter = new ArrayAdapter<>(this, R.layout.support_simple_spinner_dropdown_item, toothNumber);
    spinnerToothNumber.setAdapter(stringArrayAdapter);
}

在复选框中调用这样的方法OnCheckedChangeListener。 populateSpinner(1, 5);
