android获取全局context对象

public class MyApplication extends Application {

    private static Context context;

    @Override
    public void onCreate() {
        super.onCreate();
        context = getApplicationContext();
    }

    public static Context getContext() {
        return context;
    }
}

AndroidManifest.xml中给application配置name：com.xxx.xxx.MyApplication

使用方式: MyApplication.getContext();
