Question

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

- edit1
- edit2
- edit3
- edit4

我有2个微调器条目数组：

- spinner1
- spinner2

规则：如果我在edit1和edit2中写，我得到spinner1; 如果我在edit3和edit4中写，我有spinner2; 如果我在edit1，edit2，edit3和endit4中写，我有spinner1。

我不能只完成1个EditText，第2个，2个持续，或4个EditText。

我的微调器在strings.xml中：

<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>

我尝试了两种方法来填充我的微调器：

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，当我点击我的微调器时，焦点仍然在我的EditText中，第二个也是因为当我点击Spinner时它会出错：我无法滚动微调器。

的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" />

我尝试使用xml中的条目，但没有查看错误是否来自它，但仍然无效。

我认为有两种解决方案： - 用户滚动时退出焦点; - 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
