我正在尝试设置提醒。有一个具有 5 个值 (1,2,3,4,5) 的微调器。假设如果用户从微调器中选择 3，则应该显示 3 个“添加时间”按钮。同样，如果用户选择 5，则应显示五个“添加时间”按钮。

用户按下“添加时间”按钮，将显示时间选择器以选择提醒时间。我通过 res/string 文件夹中的 xml 创建了微调器，并设置了一个包含 5 个项目（1、2、3、4、5）的数组。我不知道根据从微调器中选择的值来显示这些“添加时间”按钮。

非常感谢任何建议/指导。

非常感谢...

试试这个代码。

    list = (LinearLayout)findViewById(R.id.list);

    ArrayAdapter<CharSequence> adapterSpinner = ArrayAdapter.createFromResource(this,
            R.array.number, android.R.layout.simple_spinner_item);
 adapterSpinner.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(adapterSpinner);

    spinner.setOnItemSelectedListener(this);
}

public void addButton(int number){
    list.removeAllViews();
    for(int i = 0; i<number; i++){
        Button button = new Button(getApplicationContext());
        button.setText("Add Time");
        list.addView(button);
    }
}

@Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
    switch (i){
        case 0:
            addButton(1);
            break;
        case 1:
            addButton(2);
            break;
        case 2:

            break;
        case 3:
            addButton(4);
            break;
        case 4:
            addButton(5);
            break;
    }
}

@Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
}

main_activity.xml
