Android全局主题样式控制，语言设置、主题颜色、字体大小、字体样式、长短震动、铃声设置，App必备实用功能集合
涉及Mp3播放服务 本地数据储存读写 代码简明易懂，适合初学者 使用开发工具 Android Studio 3.2 开发环境：JDK 1.8
废话不多说，有图有真相
【语言设置的效果】
【字体和字体大小设置的效果】
【主题颜色设置的效果】
【效果会和其他页面以及弹出的Toast同步】
 震动和铃声就没办法截图啦！
核心代码架构如下：
【主页面布局代码】
【Mp3 服务】
public class MusicService extends Service {
private MediaPlayer mMediaPlayer; //定义一个媒体文件
@Override
public void onCreate() {
super.onCreate();
L.e("onCreate");
int RingtoneType = DataAccess.ReadDataInt(this,"RINGTONE");
if (RingtoneType != 0){
switch (RingtoneType){
case 1:
mMediaPlayer = MediaPlayer.create(this,R.raw.ringtone01_9420); //引入mp3文件
break;
case 2:
mMediaPlayer = MediaPlayer.create(this,R.raw.ringtone02_matteo_panama); //引入mp3文件
break;
case 3:
mMediaPlayer = MediaPlayer.create(this,R.raw.ringtone03_planef); //引入mp3文件
break;
}
}
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
L.e("onStartCommand");
mMediaPlayer.start(); //启动媒体文件
return super.onStartCommand(intent, flags, startId);
}
@Override
public void onDestroy() {
L.e("onDestroy");
mMediaPlayer.stop(); //停止播放
super.onDestroy();
}
@Override
public IBinder onBind(Intent intent) {
L.e("onBind");
return null;
}
}
【BaseActivity】
public class BaseActivity extends AppCompatActivity {
public static Typeface typeFace;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//主题设置
setTheme();
//显示返回键
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Objects.requireNonNull(getSupportActionBar()).setDisplayHomeAsUpEnabled(true);
}
//取消任务栏（全屏）
// this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setTypeface();
}
@Override
public Resources getResources() {
float s = DataAccess.ReadDataFloat(BaseActivity.this,"size");
L.e("---------" + s);
//字体大小缩放
Resources resources = super.getResources();
Configuration configuration = resources.getConfiguration();
if(s == 0.0){
configuration.fontScale = StatcClass.Size;
}else{
configuration.fontScale = s;
}
resources.updateConfiguration(configuration, resources.getDisplayMetrics());
return resources;
}
//字体设置(需要 ： serif)
public void setTypeface(){
int fontsType = DataAccess.ReadDataInt(BaseActivity.this,"FONTS");
if(fontsType == 0){
typeFace = Typeface.createFromAsset(getAssets(), "fonts/FZHT.TTF");
}else{
switch (fontsType){
case 1: typeFace = Typeface.createFromAsset(getAssets(), "fonts/FZHT.TTF");
break;
case 2: typeFace = Typeface.createFromAsset(getAssets(), "fonts/FZXY.TTF");
break;
case 3: typeFace = Typeface.createFromAsset(getAssets(), "fonts/HWXK.TTF");
break;
case 4: typeFace = Typeface.createFromAsset(getAssets(), "fonts/HWXW.TTF");
break;
}
}
try
{
Field field = Typeface.class.getDeclaredField("SERIF");
field.setAccessible(true);
field.set(null, typeFace);
}
catch (NoSuchFieldException e)
{
e.printStackTrace();
}
catch (IllegalAccessException e)
{
e.printStackTrace();
}
}
//APP主题设置
public void setTheme(){
int ThemeType = DataAccess.ReadDataInt(BaseActivity.this,"THEME");
switch (ThemeType){
case 0: setTheme(R.style.AppTheme);
break;
case 1: setTheme(R.style.AppTheme01);
break;
case 2: setTheme(R.style.AppTheme02);
break;
case 3: setTheme(R.style.AppTheme03);
break;
case 4: setTheme(R.style.AppTheme04);

}
}
}

【DataAccess】本地数据保存/删除/读写
public class DataAccess {
/** Int **/
//储存数据
public static void SaveDataInt(Context context, String Key, int num){
//获取SharedPreferences对象
SharedPreferences sp01 = context.getSharedPreferences("SP01", MODE_PRIVATE);
//存入数据
SharedPreferences.Editor editor01 = sp01.edit();
editor01.putInt(Key, num);
editor01.apply(); //储存信息
}
//读取数据
public static int ReadDataInt(Context context, String Key){
//获取SharedPreferences对象
SharedPreferences sp01 = context.getSharedPreferences("SP01", MODE_PRIVATE);
int num = sp01.getInt(Key,0);
return num;
}
/** String **/
public static void SaveDataString(Context context, String Key, String data){
SharedPreferences sp01 = context.getSharedPreferences("SP01", MODE_PRIVATE);
SharedPreferences.Editor editor01 = sp01.edit();
editor01.putString(Key, data);
editor01.apply();
}
public static String ReadDataString(Context context, String Key){
SharedPreferences sp01 = context.getSharedPreferences("SP01", MODE_PRIVATE);
String num = sp01.getString(Key,"null");
return num;
}
/** Float **/
public static void SaveDataFloat(Context context, String Key, float data){
SharedPreferences sp01 = context.getSharedPreferences("SP01", MODE_PRIVATE);
SharedPreferences.Editor editor01 = sp01.edit();
editor01.putFloat(Key, data);
editor01.apply();
}
public static float ReadDataFloat(Context context, String Key){
SharedPreferences sp01 = context.getSharedPreferences("SP01", MODE_PRIVATE);
float num = sp01.getFloat(Key,0.0f);
return num;
}
//删除指定Key数据，当 KEY = ALL 时清空所有数据
public static void DeleteData(Context context, String Key){
//获取SharedPreferences对象
SharedPreferences sp01 = context.getSharedPreferences("SP01", MODE_PRIVATE);
SharedPreferences.Editor editor = sp01.edit();
if(Key.equals("ALL")){
editor.clear();
}else{
editor.remove(Key);
}
editor.commit();
}
}
【StatcClass】
用于默认标识
public class StatcClass {
public static float Size = 1.0f; //字体缩放倍数
public static int FONTS = 1; //字体大小
public static int THEME = 0; //主题设置
public static int RINGTONE = 0; //铃声设置
}
【创建文件夹放字体和铃声】
【主题设置】
