实现启动页与底部导航
前言
刚工作的时候与写andBase大神一起工作，所以用了很多他造的轮子，现在也会用到一些常用的工具类，封装成自己的库。
1. 使用Android 导入库 myLibary

点击File--->New---->New Module
项目 点右键 ---> OPen Module Settings
点+ 号
完成
启动页面
主页
2.实现
一.启动页面 实现可以有多种
（1）倒计时
public class MyCount extends CountDownTimer {
public MyCount(long millisInFuture, long countDownInterval) {
super(millisInFuture, countDownInterval);
}
@Override
public void onFinish() {
Intent in = new Intent(mContext, MainActivity.class);
startActivity(in);
finish();
}
@Override
public void onTick(long millisUntilFinished) {
long second = millisUntilFinished / 1000;
countButton.setText("跳过|" + second + "s");
}
}
（2）延时
new Handler().postDelayed(new Runnable() {
public void run() {
/* Create an Intent that will start the Main WordPress Activity. */
Intent mainIntent = new Intent(splashScreen.this, wpAndroid.class);
splashScreen.this.startActivity(mainIntent);
splashScreen.this.finish();
}
}, 2900);
二.底部导航(Tab)
- ViewPager + RadioButton

2.Fragment+RadioButton
http://blog.csdn.net/chinaltz/article/details/40145407 - ViewPager +TabLayout
本例实现
tabLayout.setupWithViewPager(viewPager);
//设置ViewPager 是否可以滑动
viewPager.setPagingEnabled(true);
viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
@Override
public void onPageSelected(int position) {
for (int i = 0; i < titleList.length; i++) {
TabLayout.Tab tab = tabLayout.getTabAt(i);
View view = tab.getCustomView();
ImageView img = (ImageView) view.findViewById(R.id.tab_icon);
TextView title = (TextView) view.findViewById(R.id.tab_title);
if (position == i) {
img.setImageResource(icons_press[i]);
title.setTextColor(getResources().getColor(R.color.mainColor));
} else {
img.setImageResource(icons[i]);
title.setTextColor(getResources().getColor(R.color.gray));
}
}
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
//为TabLayout添加tab名称
for (int i = 0; i < titleList.length; i++) {
TabLayout.Tab tab = tabLayout.getTabAt(i);
tab.setCustomView(getTabView(i));
}
/**
* 添加getTabView的方法，来进行自定义Tab的布局View
*
* @param position
* @return
*/
public View getTabView(int position) {
LayoutInflater mInflater = LayoutInflater.from(this);
View view = null;
view = mInflater.inflate(R.layout.item_bottom_tab, null);
AutoUtils.auto(view);
TextView tv = (TextView) view.findViewById(R.id.tab_title);
tv.setText(titleList[position]);
ImageView img = (ImageView) view.findViewById(R.id.tab_icon);
if (position == 0) {
tv.setTextColor(getResources().getColor(R.color.mainColor));
img.setImageResource(icons_press[position]);
} else {
tv.setTextColor(getResources().getColor(R.color.gray));
img.setImageResource(icons[position]);
}
return view;
}
4.BottomNavigationView 新版Android 创建项目 可以学习
GitHub 代码在这 https://github.com/chinaltz/JustAndroid
会不定时更新
