我有 2 个 AutoCompleteTextview 如何填充两者

Question

我制作了 3 个 AutoCompleteTextview，但是当我填充它时，只有第一个被填充，另一个不工作。

注意：我正在使用自定义 AutoCompleteTextview 来解决 1 个问题的阈值。

我的布局文件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

        <LinearLayout

            android:paddingBottom="@dimen/dimens_10dp">

                android:layout_height="wrap_content"
                android:layout_margin="@dimen/_16sdp"
                android:paddingStart="@dimen/_14sdp"
                android:hint="Color Preferences">

                <ctdworld.com.eid.helper.InstantAutoComplete
                    android:id="@+id/activity_quiz_project_info_2_finish_pref_spinner"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"/>

            </com.google.android.material.textfield.TextInputLayout>

</LinearLayout>

我的java代码：

String[] styleArray = getResources().getStringArray(R.array.entries_style_preference);
        ArrayAdapter styleAdapter = new ArrayAdapter(this,
                R.layout.dropdown_menu_popup_item,
                styleArray);
        styleAdapter.getFilter();
        mStylePrefSpinner.setAdapter(styleAdapter);

        String[] colorArray = getResources().getStringArray(R.array.entries_colors_preference);
        ArrayAdapter colorAdapter = new ArrayAdapter(this,
                R.layout.dropdown_menu_popup_item,
                colorArray);
        colorAdapter.getFilter();
        mStylePrefSpinner.setAdapter(colorAdapter);

        String[] finishArray = getResources().getStringArray(R.array.entries_finish_preference);
        ArrayAdapter finishAdapter = new ArrayAdapter(this,
                R.layout.dropdown_menu_popup_item,
                finishArray);
        finishAdapter.getFilter();
        mStylePrefSpinner.setAdapter(finishAdapter);

我一个一个地尝试然后它开始工作，但是当我为所有三个编写代码时，只有一个可以工作。

Answer 1

您始终将适配器分配给同一个绑定属性 mStylePrefSpinner：

...
mStylePrefSpinner.setAdapter(styleAdapter);
...
mStylePrefSpinner.setAdapter(colorAdapter);
...
mStylePrefSpinner.setAdapter(finishAdapter);

您应该将其设置为每个绑定属性。假设它们是 mStylePrefSpinner、mStyleColorSpinner & mStyleFinishSpinner:

...
mStylePrefSpinner.setAdapter(styleAdapter);
...
mStyleColorSpinner.setAdapter(colorAdapter);
...
mStyleFinishSpinner.setAdapter(finishAdapter);
