第一步,界面。
界面的思路是利用ViewPager+Fragment实现,所以activity_main.xml中添加一个ViewPager。顶部和底部include的顶部栏和底部栏后面再说。
MainActivity的界面activity_main.xml:
当然,要用到ViewPager+Fragment就要建立Fragment,如图我建了三个Fragment,这个可以根据需要自己创建。
这三个Fragment很类似,这里写出一个,其他以此类推。
package activity; import android.os.Bundle; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import com.chase.cn.money_of_my.R; /** * Created by Chase on 2017/2/6. */ public class Fragment_tab01 extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View tab01 = inflater.inflate(R.layout.fragment_tab01_home,container,false); return tab01; } }
此Fragment对应的xml文件:
现在回到MainActivity中:
package activity; import ... public class MainActivity extends FragmentActivity { private ViewPager mViewPager; private MyFragmentPagerAdapter mAdapter; private ListfragmentList; //保存界面的view @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); StatusBarUtil.setWindowStatusBarColor(this, R.color.colorTitleGray); initViews(); initDatas(); } /** * 数据初始化 */ private void initDatas() { //fragment数据源 fragmentList = new ArrayList (); fragmentList.add(new Fragment_tab01()); fragmentList.add(new Fragment_tab02()); fragmentList.add(new Fragment_tab03()); mAdapter = new MyFragmentPagerAdapter(getSupportFragmentManager(), fragmentList); mViewPager.setAdapter(mAdapter); } /** * 初始化控件 */ private void initViews() { mViewPager = (ViewPager) findViewById(R.id.vp_mainvp); } }
需要编写一个ViewPager的Adapter:
package utils; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentManager; import android.support.v4.app.FragmentPagerAdapter; import java.util.List; /** * Created by Chase on 2017/2/6. */ public class MyFragmentPagerAdapter extends FragmentPagerAdapter { private ListfragList; private List tabList; public MyFragmentPagerAdapter(FragmentManager fm, List fragList) { super(fm); this.fragList = fragList; } @Override public CharSequence getPageTitle(int position) { return tabList.get(position); } @Override public Fragment getItem(int position) { return fragList.get(position); } @Override public int getCount() { return fragList.size(); } }
现在三个Fragment已经添加到了MainActivity中,滑动ViewPager切换Fragment,同时底部的导航栏也会切换,在为ViewPager添加监听以前,先说说底部导航栏。
第二步,底部导航。
这个的切换其实就是切换准备好的png图片和改变文字的颜色。
下面是刚才导入的底部导航栏xml文件:
继续回到对应的MainActivity:并加入了按两次回退键退出程序。
package activity; import ... public class MainActivity extends FragmentActivity implements View.OnClickListener { private ViewPager mViewPager; private MyFragmentPagerAdapter mAdapter; private ListfragmentList; //保存界面的view private FrameLayout fl_page_home, fl_page_budget, fl_page_more; private LinearLayout ll_taball; private Button bt_page_home, bt_page_budget, bt_page_more; private TextView tv_page_home; private TextView tv_page_budget; private TextView tv_page_more; private TextView tv_top_title; //onkeydown_ private static boolean isQuit = false; private Timer timer = new Timer(); //onResult的码 private static final int addActivityRequestCodeOfPage2 = 0,addActivityRequestCodeOfPage1=1; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); StatusBarUtil.setWindowStatusBarColor(this, R.color.colorTitleGray); initViews(); setViewPagerEvent(); initEvents(); initDatas(); } @Override protected void onRestart() { super.onRestart(); } /** * viewPager切换页面的事件 */ private void setViewPagerEvent() { //设置viewpager的page监听换bottom按钮颜色 mViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() { @Override public void onPageSelected(int position) { int currentItem = mViewPager.getCurrentItem(); switch (currentItem) { case 0: resetImgAndTextColorAndButton(); bt_page_home.setBackgroundResource(R.drawable.home_pressed); tv_page_home.setTextColor(Color.rgb(255, 209, 0)); tv_top_title.setText("首页"); bt_add.setVisibility(View.VISIBLE); bt_add.setBackgroundResource(R.drawable.selector_main_top_menu); break; case 1: resetImgAndTextColorAndButton(); bt_page_budget.setBackgroundResource(R.drawable.budget_pressed); tv_page_budget.setTextColor(Color.rgb(255, 209, 0)); tv_top_title.setText("记录"); bt_add.setVisibility(View.VISIBLE); bt_add.setBackgroundResource(R.drawable.selector_add_button); break; case 2: resetImgAndTextColorAndButton(); bt_page_more.setBackgroundResource(R.drawable.more_pressed); tv_page_more.setTextColor(Color.rgb(255, 209, 0)); tv_top_title.setText("更多"); bt_add.setVisibility(View.INVISIBLE); break; default: break; } } @Override public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { } @Override public void onPageScrollStateChanged(int state) { } }); } /** * 数据初始化 */ private void initDatas() { //fragment数据源 fragmentList = new ArrayList (); fragmentList.add(new Fragment_tab01()); fragmentList.add(new Fragment_tab02()); fragmentList.add(new Fragment_tab03()); mAdapter = new MyFragmentPagerAdapter(getSupportFragmentManager(), fragmentList); mViewPager.setAdapter(mAdapter); } /** * 初始化事件 */ private void initEvents() { fl_page_home.setOnClickListener(this); fl_page_budget.setOnClickListener(this); fl_page_more.setOnClickListener(this); bt_add.setOnClickListener(this); } /** * 初始化控件 */ private void initViews() { mViewPager = (ViewPager) findViewById(R.id.vp_mainvp); //底部的布局 fl_page_home = (FrameLayout) findViewById(R.id.fl_page_home); fl_page_budget = (FrameLayout) findViewById(R.id.fl_page_budget); fl_page_more = (FrameLayout) findViewById(R.id.fl_page_more); //底部的按钮 bt_page_home = (Button) findViewById(R.id.bt_page_home); bt_page_budget = (Button) findViewById(R.id.bt_page_budget); bt_page_more = (Button) findViewById(R.id.bt_page_more); //按钮对应文字的颜色 tv_page_home = (TextView) findViewById(R.id.tv_page_home); tv_page_budget = (TextView) findViewById(R.id.tv_page_budget); tv_page_more = (TextView) findViewById(R.id.tv_page_more); //顶部状态栏文字 tv_top_title = (TextView) findViewById(R.id.tv_top_title); ll_taball = (LinearLayout) findViewById(R.id.ll_taball); //记一笔按钮 bt_add = (Button) findViewById(R.id.bt_add); bt_add.setVisibility(View.VISIBLE); } /** * 点击下面的布局按钮事件 * * @param v */ @Override public void onClick(View v) { resetImgAndTextColorAndButton(); switch (v.getId()) { /** * 底部导航栏按钮 */ case R.id.fl_page_home: mViewPager.setCurrentItem(0);//如果首页 切换首页 bt_page_home.setBackgroundResource(R.drawable.home_pressed);//并将按钮颜色点亮 tv_page_home.setTextColor(Color.rgb(255, 209, 0)); tv_top_title.setText("首页"); bt_add.setVisibility(View.VISIBLE); bt_add.setBackgroundResource(R.drawable.selector_main_top_menu); break; case R.id.fl_page_budget: mViewPager.setCurrentItem(1); bt_page_budget.setBackgroundResource(R.drawable.budget_pressed); tv_page_budget.setTextColor(Color.rgb(255, 209, 0)); tv_top_title.setText("记录"); bt_add.setVisibility(View.VISIBLE); bt_add.setBackgroundResource(R.drawable.selector_add_button); break; case R.id.fl_page_more: mViewPager.setCurrentItem(2); bt_page_more.setBackgroundResource(R.drawable.more_pressed); tv_page_more.setTextColor(Color.rgb(255, 209, 0)); tv_top_title.setText("更多"); bt_add.setVisibility(View.INVISIBLE); break; default: break; } } /** * 设置所有图片暗色和文字 */ private void resetImgAndTextColorAndButton() { bt_page_home.setBackgroundResource(R.drawable.home); bt_page_budget.setBackgroundResource(R.drawable.budget); bt_page_more.setBackgroundResource(R.drawable.more); tv_page_home.setTextColor(Color.rgb(56, 56, 56)); tv_page_budget.setTextColor(Color.rgb(56, 56, 56)); tv_page_more.setTextColor(Color.rgb(56, 56, 56)); } /** * 回退按钮两次退出 */ @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_BACK) { if (isQuit == false) { isQuit = true; ToastUtil.showToast(getApplicationContext(), "请按两次回退键退出", 3000); TimerTask task = null; task = new TimerTask() { @Override public void run() { isQuit = false; } }; timer.schedule(task, 2000); } else { finish(); System.exit(0); } } return true; } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (requestCode == addActivityRequestCodeOfPage2) { mViewPager.setCurrentItem(1); bt_page_budget.setBackgroundResource(R.drawable.budget_pressed); tv_page_budget.setTextColor(Color.rgb(255, 209, 0)); }else if (requestCode==addActivityRequestCodeOfPage1){ bt_page_home.setBackgroundResource(R.drawable.home_pressed); tv_page_home.setTextColor(Color.rgb(255, 209, 0)); } } }
最后加入的onActivityResult是对应如下情况,如果在某个Fragment中对应进去了其他的Activity时,返回以后导航栏是没有之前的显示的,所以如下就要返回原来的显示。
@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (requestCode == addActivityRequestCodeOfPage2) { mViewPager.setCurrentItem(1); bt_page_budget.setBackgroundResource(R.drawable.budget_pressed); tv_page_budget.setTextColor(Color.rgb(255, 209, 0)); }else if (requestCode==addActivityRequestCodeOfPage1){ bt_page_home.setBackgroundResource(R.drawable.home_pressed); tv_page_home.setTextColor(Color.rgb(255, 209, 0)); } }
第三步,顶部右上角菜单。
之前导入顶部栏的xml文件:
对应菜单我们使用PopupWindow 。
package views; import ... /** * Created by Chase on 2017/2/23. */ public class TopPopWindow extends PopupWindow { private View mView; private LinearLayout ll_popmenu_record,ll_popmenu_book,ll_popmenu_search; public TopPopWindow(Activity paramActivity, View.OnClickListener paramOnClickListener, int paramInt1, int paramInt2){ mView = LayoutInflater.from(paramActivity).inflate(R.layout.popwindow_topright, null); ll_popmenu_record = (LinearLayout) mView.findViewById(R.id.ll_popmenu_record); ll_popmenu_book = (LinearLayout) mView.findViewById(R.id.ll_popmenu_book); ll_popmenu_search = (LinearLayout) mView.findViewById(R.id.ll_popmenu_search); if (paramOnClickListener != null){ //设置点击监听 ll_popmenu_record.setOnClickListener(paramOnClickListener); ll_popmenu_book.setOnClickListener(paramOnClickListener); ll_popmenu_search.setOnClickListener(paramOnClickListener); setContentView(mView); //设置宽度 setWidth(paramInt1); //设置高度 setHeight(paramInt2); //设置显示隐藏动画 setAnimationStyle(R.style.AnimTools); //设置背景透明 setBackgroundDrawable(new ColorDrawable(0)); } } }
编写PopupWindow 的xml:
回到MainActivity:

右上角的按钮还添加了功能,在不同的Fragment中,它的功能不同。
