左右效果图如下:
左边
右边
Android SlidingMenu(SlideMenu)是一个开源项目框架。在git上的下载地址:https://github.com/jfeinstein10/SlidingMenu
现在基于Fragment给出一个简单的左边+右边的SlidingMenu(SlideMenu) 。首先要引入第三方库,这不比多说,现到git上把最新的项目代码下载到本地然后导入到工程中,接下来就是导入和写自己的代码。
主Activity:
<span style="font-size:14px;">package zhangphil.slidingmenu;
import com.jeremyfeinstein.slidingmenu.lib.SlidingMenu;
import android.graphics.Color;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;
import android.view.Gravity;
import android.view.KeyEvent;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
public class MainActivity extends FragmentActivity {
private SlidingMenu menu;
// id用于区分左边还是右边的侧边滑menu
private final static String ID = "id";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
menu = new SlidingMenu(this);
// 左边和右边均有
menu.setMode(SlidingMenu.LEFT_RIGHT);
menu.attachToActivity(this, SlidingMenu.SLIDING_CONTENT);
// 左边
menu.setMenu(R.layout.left_menu);
// 右边
menu.setSecondaryMenu(R.layout.right_menu);
Fragment leftFragment = TestFragment.newInstance("左边");
Fragment rightFragment = TestFragment.newInstance("右边");
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.left, leftFragment);
ft.commit();
// 必须重新再次获得一个FragmentTransaction。否则报错。
ft = fm.beginTransaction();
ft.replace(R.id.right, rightFragment);
ft.commit();
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
// 按下BACK + 没有重复
if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0) {
// 用户按返回键后,切换SlideMenu <-->主界面。
menu.toggle(true);
return true;
}
return super.onKeyDown(keyCode, event);
}
//
// 仅仅用于生成测试的Fragment。
//
public static class TestFragment extends Fragment {
public static Fragment newInstance(String id) {
Fragment fragment = new TestFragment();
Bundle bundle = new Bundle();
bundle.putString(ID, id);
fragment.setArguments(bundle);
return fragment;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// 仅仅显示一个TextView。
TextView tv = new TextView(getActivity());
tv.setTextColor(Color.BLACK);
tv.setText(this.getArguments().getString(ID) + "");
tv.setTextSize(60.0f);
tv.setGravity(Gravity.CENTER);
return tv;
}
}
}</span>
重写了onKeyDown,为了捕捉用户按击返回键的事件,以便切换。
