Question

我试图在运行时将一些视图注入线性布局，点击一下按钮。

我的测试环境是API 21和API 16. FOr API 21一切都很好我得到了材料微调器。在API 16上进行测试时，我获得了在XML中定义的所有视图的Material微调器，但是当我使用以下方法动态生成和注入一个sinner时，我获得API级别16微调器。

代码：

 public void addView(LinearLayout container, String[] spin_array, String hint, int inputType, int tagger) {

        LayoutInflater layoutInflater = (LayoutInflater) getActivity().getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        final View addView = layoutInflater.inflate(R.layout.add_company_fragment_two_dynamic_content, null);

        final Spinner spin_dynamic = (Spinner) addView.findViewById(R.id.email_spinner1);
        EditText edt_dynamic = (EditText) addView.findViewById(R.id.edittext_email1);
        ImageView remove_dynamic = (ImageView) addView.findViewById(R.id.btn_remove);


        edt_dynamic.setHint(hint);
        setUpSpinners(spin_array, spin_dynamic);
        edt_dynamic.setTag(container.getTag() + "edt" + tagger);
        edt_dynamic.setInputType(inputType);
        edt_dynamic.setTypeface(roboto_condenced_light);
        spin_dynamic.setTag(container.getTag() + "spin" + tagger);

        idsMap.put(spin_dynamic.getTag().toString(), edt_dynamic.getTag().toString());

        // get height from dimens
        int height = (int) getResources().getDimension(R.dimen.lin_height);
        // set this height
        LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, height);

        // we are only concerned about top margin here.
        layoutParams.setMargins(0, (int) getResources().getDimension(R.dimen.topMargin), 0, 0);
        container.addView(addView, 1, layoutParams);

        remove_dynamic.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //Remove View (LinearLayout) and also remove the key from idsMap so that we dont get a NullPointer later
                ((LinearLayout) addView.getParent()).removeView(addView);
                idsMap.remove(spin_dynamic.getTag().toString());
            }
        });
    }


 public void setUpSpinners(String[] spin_array, Spinner spin) {

        ArrayAdapter<String> adapter = new ArrayAdapter<>(getActivity(), android.R.layout.simple_spinner_item, spin_array);
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spin.setAdapter(adapter);
    }

XML文件add_company_fragment_two_dynamic_content

<?xml version="1.0" encoding="utf-8"?>

屏幕抓取：

以下是此活动的styles.xml条目：

<style name="CompanyPagerTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="colorControlActivated">@color/colorPrimary</item>
        <item name="colorControlNormal">#adadad</item>
        <item name="colorControlHighlight">@color/colorPrimaryDark</item>
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
        <item name="android:textColorHint">#adadad</item>
    </style>

这是我的Gradle条目：

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile 'com.android.support:recyclerview-v7:23.1.1'
}

我在这里想念什么？我还发现涟漪在API 21下无法正常工作

Spinner在API 16和API 21上的呈现方式不同
