Android怎么給應(yīng)用定制皮膚

本文小編為大家詳細介紹“Android怎么給應(yīng)用定制皮膚”，內(nèi)容詳細，步驟清晰，細節(jié)處理妥當，希望這篇“Android怎么給應(yīng)用定制皮膚”文章能幫助大家解決疑惑，下面跟著小編的思路慢慢深入，一起來學(xué)習新知識吧。

先說思路:

1）皮膚也就是相關(guān)的資源文件單獨放置在某個工程中,一種皮膚一個工程文件.一個工程包括N多的資源文件,多個工程間資源的關(guān)系是,文件名,資源ID等完全一樣.不同的可能是圖片資源,style等的設(shè)置不一樣.

皮膚工程在AndroidManifest.xml中配置android:sharedUserId="com.eric.skinmain".

表明允許com.eric.skinmain訪問本工程中的資源文件. com.eric.skinmain是主項目的包名

3）主項目通過 this.createPackageContext("com.eric.blackskin",Context.CONTEXT_IGNORE_SECURITY);

獲取到com.eric.blackskin對應(yīng)的Context,然后通過返回的context對象就可以訪問到com.eric.blackskin中的任何資源,如同訪問自身的資源一樣.

注：記得先安裝皮膚工程對應(yīng)的apk文件.

public class main extends Activity {         /** Called when the activity is first created. */         private LinearLayout showBg;         private Button btn;         private Context green_skin_Context = null;         private Context black_skin_Context = null;         int flag = 0;          @Override         public void onCreate(Bundle savedInstanceState) {                 super.onCreate(savedInstanceState);                 setContentView(R.layout.main);                 showBg = (LinearLayout) findViewById(R.id.linear_layout_1);                 try {                         green_skin_Context = this.createPackageContext(                                         "com.eric.greenskin", Context.CONTEXT_IGNORE_SECURITY);                 } catch (NameNotFoundException e) {                         e.printStackTrace();                 }                 try {                         black_skin_Context = this.createPackageContext(                                         "com.eric.blackskin", Context.CONTEXT_IGNORE_SECURITY);                 } catch (NameNotFoundException e) {                         e.printStackTrace();                 }                 btn = (Button) findViewById(R.id.btn_change_skin);                 btn.setOnClickListener(new OnClickListener() {                         @Override                         public void onClick(View v) {                                 if (flag == 0) {                                         showBg.setBackgroundDrawable(green_skin_Context                                                         .getResources().getDrawable(R.drawable.bg));                                         btn.setBackgroundDrawable(green_skin_Context                                                         .getResources().getDrawable(R.drawable.btn_normal));                                                                                  flag = 1;                                 } else if (flag == 1) {                                         showBg.setBackgroundDrawable(black_skin_Context                                                         .getResources().getDrawable(R.drawable.bg));                                         btn.setBackgroundDrawable(black_skin_Context                                                         .getResources().getDrawable(R.drawable.btn_normal));                                         flag = 0;                                 }                         }                 });         } }
