AndroidUI--SlidingMenu使用例子,android面试试题

private void initSlidingMenu(Bundle savedInstanceState) {

// 如果保存的状态不为空则得到之前保存的Fragment,否则实例化MyFragment

if (savedInstanceState != null) {

mContent = getSupportFragmentManager().getFragment(

savedInstanceState, “mContent”);

}

if (mContent == null) {

mContent = new MyFragment();

}

// 设置主界面视图

setContentView(R.layout.content_frame);

getSupportFragmentManager().beginTransaction()

.replace(R.id.content_frame, new MyFragment()).commit();

// 设置滑动菜单的视图

setBehindContentView(R.layout.menu_frame);

getSupportFragmentManager().beginTransaction()

.replace(R.id.menu_frame, new SampleListFragment()).commit();

// 实例话滑动菜单对象

SlidingMenu sm = getSlidingMenu();

// 设置滑动阴影的宽度

sm.setShadowWidthRes(R.dimen.shadow_width);

// 设置滑动阴影的图像资源

sm.setShadowDrawable(R.drawable.shadow);

// 设置滑动菜单视图的宽度

sm.setBehindOffsetRes(R.dimen.slidingmenu_offset);

// 设置渐入渐出效果的值

sm.setFadeDegree(0.35f);

// 设置触摸屏幕的模式

sm.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);

}
