上一篇《是男人就下100层【第一层】——高仿微信界面(3)》中我们完成了登录,这一篇看完成登录后的一个短暂加载和引导界面。
加载界面:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" > <RelativeLayout android:layout_width="180dp" android:layout_height="180dp" android:layout_centerInParent="true" android:background="@drawable/loading_bg" > <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" android:orientation="vertical" > <ProgressBar android:id="@+id/progressBar1" style="?android:attr/progressBarStyleLarge" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="正在登录" android:layout_marginTop="10dp" android:textColor="#fff" android:textSize="20sp" /> </LinearLayout> </RelativeLayout> </RelativeLayout>定义了一个ProgressBar,效果如下:
再来看看引导界面的实现
<?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <android.support.v4.view.ViewPager android:id="@+id/whatsnew_viewpager" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" > </android.support.v4.view.ViewPager> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" > <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_gravity="bottom" android:layout_marginBottom="30dp" android:gravity="center_horizontal" > <ImageView android:id="@+id/page0" android:layout_width="wrap_content" android:layout_height="wrap_content" android:scaleType="matrix" android:src="@drawable/page_now" /> <ImageView android:id="@+id/page1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:scaleType="matrix" android:src="@drawable/page" /> <ImageView android:id="@+id/page2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:scaleType="matrix" android:src="@drawable/page" /> <ImageView android:id="@+id/page3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:scaleType="matrix" android:src="@drawable/page" /> <ImageView android:id="@+id/page4" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:scaleType="matrix" android:src="@drawable/page" /> <ImageView android:id="@+id/page5" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:scaleType="matrix" android:src="@drawable/page" /> </LinearLayout> </LinearLayout> </FrameLayout>
在上面我们使用到了一个ViewPager组件,这个组件的作用是时图片可以左右滑动,使用方法详见:http://www.uml.org.cn/mobiledev/201211294.asp
定义的ViewPage的适配器以及下部的选中状态ImageView的设置如下:
package com.example.weixin.activity; import java.util.ArrayList; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.support.v4.view.PagerAdapter; import android.support.v4.view.ViewPager; import android.support.v4.view.ViewPager.OnPageChangeListener; import android.view.LayoutInflater; import android.view.View; import android.widget.ImageView; import com.example.weixin.R; public class Whatsnew extends Activity { private ViewPager mViewPager; private ImageView mPage0; private ImageView mPage1; private ImageView mPage2; private ImageView mPage3; private ImageView mPage4; private ImageView mPage5; private int currIndex = 0; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.whatsnew_viewpager); mViewPager = (ViewPager)findViewById(R.id.whatsnew_viewpager); mViewPager.setOnPageChangeListener(new MyOnPageChangeListener()); mPage0 = (ImageView)findViewById(R.id.page0); mPage1 = (ImageView)findViewById(R.id.page1); mPage2 = (ImageView)findViewById(R.id.page2); mPage3 = (ImageView)findViewById(R.id.page3); mPage4 = (ImageView)findViewById(R.id.page4); mPage5 = (ImageView)findViewById(R.id.page5); //将要分页显示的View装入数组中 LayoutInflater mLi = LayoutInflater.from(this); View view1 = mLi.inflate(R.layout.whats1, null); View view2 = mLi.inflate(R.layout.whats2, null); View view3 = mLi.inflate(R.layout.whats3, null); View view4 = mLi.inflate(R.layout.whats4, null); View view5 = mLi.inflate(R.layout.whats5, null); View view6 = mLi.inflate(R.layout.whats6, null); //每个页面的view数据 final ArrayList<View> views = new ArrayList<View>(); views.add(view1); views.add(view2); views.add(view3); views.add(view4); views.add(view5); views.add(view6); //填充ViewPager的数据适配器 PagerAdapter mPagerAdapter = new PagerAdapter() { @Override public boolean isViewFromObject(View arg0, Object arg1) { return arg0 == arg1; } @Override public int getCount() { return views.size(); } @Override public void destroyItem(View container, int position, Object object) { ((ViewPager)container).removeView(views.get(position)); } @Override public Object instantiateItem(View container, int position) { ((ViewPager)container).addView(views.get(position)); return views.get(position); } }; mViewPager.setAdapter(mPagerAdapter); } public class MyOnPageChangeListener implements OnPageChangeListener { @Override public void onPageSelected(int arg0) { switch (arg0) { case 0: mPage0.setImageDrawable(getResources().getDrawable(R.drawable.page_now)); mPage1.setImageDrawable(getResources().getDrawable(R.drawable.page)); break; case 1: mPage1.setImageDrawable(getResources().getDrawable(R.drawable.page_now)); mPage0.setImageDrawable(getResources().getDrawable(R.drawable.page)); mPage2.setImageDrawable(getResources().getDrawable(R.drawable.page)); break; case 2: mPage2.setImageDrawable(getResources().getDrawable(R.drawable.page_now)); mPage1.setImageDrawable(getResources().getDrawable(R.drawable.page)); mPage3.setImageDrawable(getResources().getDrawable(R.drawable.page)); break; case 3: mPage3.setImageDrawable(getResources().getDrawable(R.drawable.page_now)); mPage4.setImageDrawable(getResources().getDrawable(R.drawable.page)); mPage2.setImageDrawable(getResources().getDrawable(R.drawable.page)); break; case 4: mPage4.setImageDrawable(getResources().getDrawable(R.drawable.page_now)); mPage3.setImageDrawable(getResources().getDrawable(R.drawable.page)); mPage5.setImageDrawable(getResources().getDrawable(R.drawable.page)); break; case 5: mPage5.setImageDrawable(getResources().getDrawable(R.drawable.page_now)); mPage4.setImageDrawable(getResources().getDrawable(R.drawable.page)); break; } currIndex = arg0; //animation.setFillAfter(true);// True:图片停在动画结束位置 //animation.setDuration(300); //mPageImg.startAnimation(animation); } @Override public void onPageScrolled(int arg0, float arg1, int arg2) { } @Override public void onPageScrollStateChanged(int arg0) { } } public void startbutton(View v) { Intent intent = new Intent(); intent.setClass(Whatsnew.this,WhatsnewDoor.class); startActivity(intent); this.finish(); } }最后的运行效果:
