public class MyApp extends Application { private Integer[] state; public Integer[] getState() { return state; } public void setState(Integer[] state) { this.state = state; } @Override public void onCreate() { // TODO Auto-generated method stub super.onCreate(); setState(we); }//一定要在onCreate方法里给变量赋值 public Integer[] we=new Integer[]{ R.drawable.b_0,R.drawable.b_1,R.drawable.b_2, R.drawable.b_3,R.drawable.b_4,R.drawable.b_5 }; }
在所需要的activity中使用
MyApp appState = (MyApp)getApplicationContext(); Integer[] we = appState.getState();
来获取,最后一步别忘了在manifest中的application标签中添加 android:name=".MyApp"(这儿不是新建<application></application>)
