换肤效果演示
四种皮肤切换:默认白色、蓝色、绿色和玫瑰红:
前言
先给大家介绍一下现在比较主流的、Star比较多的换肤框架:
- Android-skin-support 5.2K Star 传送地址:https://github.com/ximsfei/Android-skin-support
- MagicaSakura 3.4K Star 传送地址:https://github.com/bilibili/MagicaSakura
- Colorful 3.1K Star 传送地址:https://github.com/garretyoder/Colorful
- ThemeSkinning 827 Star 传送地址:https://github.com/burgessjp/ThemeSkinning
而我这篇文章讲的是基于Android-skin-support框架实现的Android应用内换肤,在此非常感谢这个换肤框架的作者,因为他的默默付出,使我们的开发更加简单快捷,而且这个换肤框架的功能非常强大:支持应用内换肤、插件式换肤(包括zip包资源换肤),学习成本低,快速上手,代码侵入性低还有最重要的用户体验极佳。
如何实现一键换肤?
下面内容是基于上面演示的demo:
使用的布局是android.support.constraint.ConstraintLayout
使用的控件有 ImageView、TextView、Button、RecyclerView、AlertDialog、RadioGroup和RadioButton:

</android.support.constraint.ConstraintLayout>
- 导入
demo中用到了android.support.constraint.ConstraintLayout
,添加以下依赖:
implementation 'skin.support:skin-support:3.1.4'
implementation 'skin.support:skin-support-constraint-layout:3.1.4'
如果用到了material design控件或者CardView v7 控件可以添加下面依赖:
implementation 'skin.support:skin-support-design:3.1.4' // skin-support-design material design 控件支持
implementation 'skin.support:skin-support-cardview:3.1.4' // skin-support-cardview CardView 控件支持
- 初始化
如果项目中没有Application,可以新建Application,在onCreate()
方法中初始化:
@Override
public void onCreate() {
super.onCreate();
SkinCompatManager.withoutActivity(this)
.addInflater(new SkinConstraintViewInflater())
.loadSkin();
}
如果用到了material design控件或者CardView v7 控件,可以这样写:
SkinCompatManager.withoutActivity(this) // 基础控件换肤初始化
.addInflater(new SkinMaterialViewInflater()) // material design 控件换肤初始化[可选]
.addInflater(new SkinConstraintViewInflater()) // ConstraintLayout 控件换肤初始化[可选]
.addInflater(new SkinCardViewInflater()) // CardView v7 控件换肤初始化[可选]
.loadSkin();
项目中的Activity如果继承AppCompatActivity,需要重载getDelegate()
方法:
@NonNull
@Override
public AppCompatDelegate getDelegate() {
return SkinAppCompatDelegateImpl.get(this, this);
}
- 最重要的一步,也是比较繁琐,准备皮肤包。
应用内换肤
,皮肤名为: blue、green、rosered
, 新增需要换肤的资源添加上面三种后缀,如图所示:
如何新建皮肤资源?
右键app
选择New -> Folder -> Res Folder
改变Res Folder
路径,新建res-green
和res-rosered
同理:
三个换肤资源新建完成之后,在build.gradle
中检查一下:
sourceSets {
main {
res.srcDirs = ['src/main/res', 'src/main/res-blue', 'src/main/res-green', 'src/main/res-rosered']
}
}
将各皮肤的资源文件复制进相应的文件夹,举例子:
默认的res文件夹
:
新建的res-blue文件夹
:
看到上面的区别了吗?基本上layout文件用到的drawable,需要换肤的都要加上相应皮肤资源名字的后缀!
还有res-blue
下的colors
,需要改变颜色的也要加上相应皮肤资源名字的后缀!
与res
下的colors
对比:
res-green
和res-rosered
皮肤资源准备步骤跟上面一致,就不再详细描述了。
- 最后一步!一键换肤!
demo示例,加载皮肤资源:
switch (checkedId) {
case R.id.rb_blue:
SkinCompatManager.getInstance()
.loadSkin("blue", null, SkinCompatManager.SKIN_LOADER_STRATEGY_BUILD_IN);
skin = "蓝色";
break;
case R.id.rb_green:
SkinCompatManager.getInstance()
.loadSkin("green", null, SkinCompatManager.SKIN_LOADER_STRATEGY_BUILD_IN);
skin = "绿色";
break;
case R.id.rb_rose_red:
SkinCompatManager.getInstance()
.loadSkin("rosered", null, SkinCompatManager.SKIN_LOADER_STRATEGY_BUILD_IN);
skin = "玫瑰红";
break;
case R.id.rb_default:
SkinCompatManager.getInstance().restoreDefaultTheme();
break;
default:break;
}
最后贴上MainActivity代码,仅供参考:
public class MainActivity extends AppCompatActivity {
@BindView(R.id.tv_show)
TextView mTvShowText;
@BindView(R.id.rv_bts)
RecyclerView mRvBts;
private String inputText = "";
private AlertDialog mAlertDialog;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.bind(this);
init();
}
private void init() {
final List<ViewBean> viewBeans = new ArrayList<>();
viewBeans.add(new ViewBean("A"));
viewBeans.add(new ViewBean("B"));
viewBeans.add(new ViewBean("C"));
viewBeans.add(new ViewBean("D"));
viewBeans.add(new ViewBean("E"));
viewBeans.add(new ViewBean("F"));
viewBeans.add(new ViewBean("1"));
viewBeans.add(new ViewBean("0"));
viewBeans.add(new ViewBean("清空"));
ViewBeanAdapter viewBeanAdapter = new ViewBeanAdapter(R.layout.item_button, viewBeans);
mRvBts.setLayoutManager(new GridLayoutManager(this, 3));
mRvBts.setAdapter(viewBeanAdapter);
viewBeanAdapter.setOnItemClickListener(new BaseQuickAdapter.OnItemClickListener() {
@Override
public void onItemClick(BaseQuickAdapter adapter, View view, int position) {
if (position == 8) {
inputText = "";
mTvShowText.setText(inputText);
return;
}
String text = viewBeans.get(position).getName();
inputText += text;
mTvShowText.setText(inputText);
}
});
mAlertDialog = new AlertDialog.Builder(this).create();
View view = View.inflate(this, R.layout.view_dialog, null);
RadioGroup rgSkinCheck = view.findViewById(R.id.rg_skin_check);
rgSkinCheck.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
switch (checkedId) {
case R.id.rb_blue:
SkinCompatManager.getInstance()
.loadSkin("blue", null, SkinCompatManager.SKIN_LOADER_STRATEGY_BUILD_IN);
break;
case R.id.rb_green:
SkinCompatManager.getInstance()
.loadSkin("green", null, SkinCompatManager.SKIN_LOADER_STRATEGY_BUILD_IN);
break;
case R.id.rb_rose_red:
SkinCompatManager.getInstance()
.loadSkin("rosered", null, SkinCompatManager.SKIN_LOADER_STRATEGY_BUILD_IN);
break;
case R.id.rb_default:
SkinCompatManager.getInstance().restoreDefaultTheme();
break;
default:break;
}
}
});
mAlertDialog.setView(view, 0, 0, 0, 0);
}
@OnClick(R.id.bt_switch_skin)
public void onSwitchSkin() {
mAlertDialog.show();
if (null != mAlertDialog.getWindow())
mAlertDialog.getWindow().setLayout(800, ViewGroup.LayoutParams.WRAP_CONTENT);
}
@NonNull
@Override
public AppCompatDelegate getDelegate() {
return SkinAppCompatDelegateImpl.get(this, this);
}
@Override
protected void onDestroy() {
super.onDestroy();
if (null != mAlertDialog) mAlertDialog.dismiss();
}
}
看到最后是不是觉得一键换肤非常简单呢!纸上得来终觉浅,绝知此事要躬行!非常感谢你能看到这里,如果能够帮助到你是我的荣幸!
