在 EditText 更改后更改 Spinner 条目

Question

我想在更改我的 EditText 后更改我的 Spinner 条目：我有 4 个 EditText:

- edit1
- edit2
- edit3
- edit4

我有 2 个微调条目数组：

- spinner1
- spinner2

规则：如果我在 edit1 和 edit2 中写入，我会得到 spinner1；如果我在 edit3 和 edit4 中编写，我有 spinner2；如果我在 edit1、edit2、edit3 和 endit4 中写入，我有 spinner1。

我不能只完成 1 个 EditText，首先是 2 个，最后是 2 个，或者是第 4 个 EditText。

我的微调器在 strings.xml:

<string-array name="dureeRemboursement">
    <item>- Choisir -</item>
    <item>5</item>
    <item>6</item>
    <item>7</item>
    <item>8</item>
    <item>9</item>
    <item>10</item>
    <item>11</item>
    <item>12</item>
    <item>13</item>
    <item>14</item>
    <item>15</item>
    <item>16</item>
    <item>17</item>
    <item>18</item>
    <item>19</item>
    <item>20</item>
    <item>21</item>
    <item>22</item>
    <item>23</item>
    <item>24</item>
    <item>25</item>
</string-array>

<string-array name="dureeRemboursementcc">
    <item>- Choisir -</item>
    <item>5</item>
    <item>6</item>
    <item>7</item>
    <item>8</item>
    <item>9</item>
    <item>10</item>
    <item>11</item>
    <item>12</item>
</string-array>

我尝试了 2 种方法来填充微调器：

editCapitauxRestants.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (!hasFocus) {
            ArrayAdapter<CharSequence> adapter0 = ArrayAdapter.createFromResource(getActivity(), R.array.dureeRemboursementcc, android.R.layout.simple_spinner_item);
            adapter0.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
            ArrayAdapter<CharSequence> adapter1 = ArrayAdapter.createFromResource(getActivity(), R.array.dureeRemboursement, android.R.layout.simple_spinner_item);
            adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

            if (editMensualitesTotales.getText().length() > 0 && editCapitauxRestants.getText().length() > 0) {
                spinnerDureeRemboursement.setAdapter(adapter1);
            } else {
                spinnerDureeRemboursement.setAdapter(adapter0);
            }
        }
    }
});


spinnerDureeRemboursement.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
        ArrayAdapter<CharSequence> adapter0 = ArrayAdapter.createFromResource(getActivity(), R.array.dureeRemboursementcc, android.R.layout.simple_spinner_item);
        adapter0.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        ArrayAdapter<CharSequence> adapter1 = ArrayAdapter.createFromResource(getActivity(), R.array.dureeRemboursement, android.R.layout.simple_spinner_item);
        adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

        if (editMensualitesTotales.getText().length() > 0 && editCapitauxRestants.getText().length() > 0) {
            spinnerDureeRemboursement.setAdapter(adapter1);
        }
    }

    public void onNothingSelected(AdapterView<?> arg0) {
    }
});

第一个不起作用，因为当我单击微调器时焦点仍在我的 EditText 中，第二个也是因为当我单击微调器时出现错误：我无法滚动微调器。

xml:

    <Spinner
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/spinnerDureeRemboursement"
        android:layout_below="@+id/dureeRemboursement"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:entries="@array/dureeRemboursementcc"
        android:focusable="true"
        android:focusableInTouchMode="true"
        android:paddingTop="20dp"
        android:paddingBottom="20dp" />

我尝试了 xml 中的条目，但没有看到错误是否来自它，但仍然不起作用。

我认为有两种解决方案： - 当用户滚动时退出焦点； - 请专注于我的微调器。

Answer 1

    private String editString1,editString2,editString3,editString4;
    public void onCreate(){
    //Initialise views
    edit1.addTextChangedListener(new TextWatcher() {
          @Override
          public void afterTextChanged(Editable s) {
            editString1 = s.toString();   setupSpinner(editString1,editString2,editString3,editString4)
        })
       //DO the same for other edit texts and save them to appropriate Strings
    }

   public void setupSpinner(String first,String second,String third,String four){
       //Check the strings and set up your spinners appropriately
    }

在 EditText 更改后更改 Spinner 条目

Change Spinner entries after EditText changes

android

android-edittext

spinner

populate
