Android - style.xml 无效

Question

我找到了带有说明的主题 - 如何为整个应用程序设置主题：

Setting global styles for Views in Android

它根本不适合我。这是我的代码：

style.xml：

<resources xmlns:android="http://schemas.android.com/apk/res/android">
    <!--1-->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="android:radioButtonStyle">@style/TBRadioButtonStyle</item>
    </style>

    <style name="TBRadioButtonStyle" parent="android:Widget.CompoundButton.RadioButton">
        <item name="android:textColor">#F00</item>
        <item name="android:textStyle">bold</item>
        <item name="android:background">@drawable/state_color_selector</item>
    </style>

</resources>

state_color_selector.xml：

<?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:state_checked="true">
            <color android:color="#F00" />
        </item>
        <item android:state_checked="false">
            <color android:color="#0F0" />
        </item>
    </selector>

AndroidManifest.xml：

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

        <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

        <application
            android:name=".controller.ApplicationController"
            android:allowBackup="true"
            android:icon="@mipmap/ic_launcher"
            android:label="@string/app_name"
            android:theme="@style/AppTheme" >
            <activity
                android:name=".view.DrawersWidget"
                android:label="@string/app_name" >
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />

                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
            </activity>
        </application>

    </manifest>

带有 RadioButton 创建的.java 文件：

RadioButton newButton = new RadioButton(ApplicationController.INSTANCE.getApplicationContext());
//...
newButton.setLayoutParams(new RadioGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.MATCH_PARENT));
newButton.setButtonDrawable(new BitmapDrawable(ApplicationController.INSTANCE.getResources(), filteredBitmap));
newButton.setText(someText);

Answer 1

当您创建 RadioButton 时，请使用 Activity 的上下文，而不是 ApplicationContext。
