Android实战:手把手实现“捧腹网”APP(一)—–捧腹网网页分析、数据获取
Android实战:手把手实现“捧腹网”APP(二)—–捧腹APP原型设计、实现框架选取
Android实战:手把手实现“捧腹网”APP(三)—–UI实现,逻辑实现
APP页面实现
根据原型图,我们可以看出,UI分为两部分,底部Tab导航+上方列表显示。 所以此处,我们通过 FragmentTabHost+Fragment,来实现底部的导航页面,通过RecyclerView来实现列表页面。
因为篇幅原因,关于FragmentTabHost和RecyclerView的使用,不多做介绍,可以建议参考: FragmentTabHost使用方法及RecycleView_PullToRefresh_LoadMore两篇文章,其中后者关于Recyclerview的项目是我之前封装的一个支持下拉刷新,加载更多,添加Header和Footer等功能的RecyclerView,便于使用。
此处,再多说一点,因为是我们做自己来实现该ui,没美工给我设计图,切图标, 所以我们需要自己去找图标,此处推荐Iconfont-阿里巴巴矢量图标库, 在这里,我们可以找到很多的图标,选择适用的几个即可。
篇幅原因,具体的页面布局、实现代码,我这里就不多贴,有兴趣的,可以直接看源码,此处,只贴出列表list_item的页面布局代码。
从原型图中,我们可以看出,列表的显示分为纯文显示和图片显示,所以我们的item布局,应该要兼容这两种显示方式。

效果图:
我们只需要在实现的逻辑上,控制文字、图片的显隐就好了。
APP逻辑功能实现
1.数据获取,实现列表适配器
在第一章捧腹网网页分析、数据获取中,我已经讲过了如何去解析网页中的数据为我们所用,拿到数据后,我们需要用这些数据填充RecyclerView,此处,使用的是我已经封装好的RecyclerView,支持翻页加载数据。

对于RecyclerView的适配器RecyclerView.Adapter的使用方式,相信玩过它的人都很熟悉,里面的方法不多介绍,主要讲下图片处理这块的实现:
String url = dataBean.getShowImg();
String gifUrl = dataBean.getGifsrcImg();
System.out.println("url : " + url + " gifUrl : " + gifUrl);
if (TextUtils.isEmpty(gifUrl)) {
Glide.with(mContext).load(url).asBitmap().diskCacheStrategy(DiskCacheStrategy.SOURCE).into(viewHolder.imgJoke);
} else {
Glide.with(mContext).load(gifUrl).asGif().diskCacheStrategy(DiskCacheStrategy.SOURCE).into(viewHolder.imgJoke);
}
app中要展示的图片,分为静态图片和动态图片,glide可以很好的处理gif动态图的加载,但是,如果像下面这样直接使用glide加载动态图,效率可是比较慢的。
Glide.with(mContext).load(gifUrl)into(viewHolder.imgJoke);
所以,在加载gif动态图的时候,我们通常使用下面这样的缓存策略
Glide.with(mContext).load(gifUrl).asGif().diskCacheStrategy(DiskCacheStrategy.SOURCE).into(viewHolder.imgJoke);
除了图片加载,还有一点需要讲解下,就是下面这段代码:
double width = Double.parseDouble(dataBean.getWidth());
double height = Double.parseDouble(dataBean.getHeight());
ViewGroup.LayoutParams lp = viewHolder.imgJoke.getLayoutParams();
lp.width = (int) (screenWidth * 0.8);
lp.height = (int) (screenWidth * 0.8 * height / width);
viewHolder.imgJoke.setLayoutParams(lp);
这段代码的意思是,在加载图片之前,先设置了ImageView的宽高。这样做的目的,是为了在图片加载显示之前就固定ImageView的大小,避免了列表因为图片高度不一致而出现“晃动”。
好,到这里,我们基本完成了列表显示功能了,接下来,在Fragment中实现功能逻辑。

功能逻辑比较简单,不多做解释。 到这里,我们的“捧腹”APP已经完成了80%了。下面,在做些扩展性的功能,使得它更像一个完整的APP。
3. 图片的大图浏览功能
上篇博文,我们就提到了,我们要使用PhotoView实现大图的浏览功能。
PhotoView的使用,可以直接在它的github官方介绍上看到,下面,我直接贴出使用代码。
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.text.TextUtils;
import android.view.View;
import android.widget.ImageView;
import com.bumptech.glide.Glide;
import com.bumptech.glide.load.engine.DiskCacheStrategy;
import butterknife.BindView;
import butterknife.ButterKnife;
import uk.co.senab.photoview.PhotoViewAttacher;
/**
* 图片浏览
*/
public class PhotoActivity extends FragmentActivity {
@BindView(R.id.imgJoke)
public ImageView imgJoke;
private String showImg;
private String gifSrcImg;
private PhotoViewAttacher mAttacher;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_photo);
ButterKnife.bind(this);
mAttacher = new PhotoViewAttacher(imgJoke);
showImg = getIntent().getStringExtra("showImg");
gifSrcImg = getIntent().getStringExtra("gifSrcImg");
System.out.println(showImg + " " + gifSrcImg);
if (TextUtils.isEmpty(gifSrcImg)) {
Glide.with(this).load(showImg).asBitmap().diskCacheStrategy(DiskCacheStrategy.SOURCE).into(imgJoke);
} else {
Glide.with(this).load(gifSrcImg).asGif().diskCacheStrategy(DiskCacheStrategy.SOURCE).into(imgJoke);
}
mAttacher.update();
mAttacher.setOnPhotoTapListener(new PhotoViewAttacher.OnPhotoTapListener() {
@Override
public void onPhotoTap(View view, float x, float y) {
PhotoActivity.this.finish();
}
@Override
public void onOutsidePhotoTap() {
PhotoActivity.this.finish();
}
});
}
}
程序中,我们添加了一个事件监听,主要是为了在用户单击图片显示或者不显示部分时,可以退出浏览。
4.为APP加入Bughd 实现崩溃分析、版本更新功能
功能做到这里,基本上完成了90%的APP,接下来,我们为其加入崩溃分析、版本更新功能。
关于如何配置,大家直接到http://bughd.com/doc/android官网看,看官方文档,为app添加功能,是开发的基本能力,而且,这个功能集成并不困难,建议大家自己添加,有疑问,可参考我最后放出的源码。
APP打包发布
截止此处,我们的“捧腹”APP基本上就已经实现了,在说打包发布之前,我要提到一个很重要的问题,那就是数据版权。 我们知道,这个app的数据,是分析“捧腹网”的网页,拿到的,我们应当尊重其版权所有。 因为我们是学习使用,所以大家应在app明显的位置,加上数据来源。这里,我选择在启动页面上添加。
接下来,就是打包发布了。关于如何打包app,限于篇幅,请参考我之前写的 Android Studio(十二):打包多个发布渠道的apk文件 ,打包apk成功后,我们将其发布在fir.im免费托管分发服务的平台上,方便大家下载测试。(如果没问题,可以上传到应用市场)。
最后,让我们看下APP最终效果。
项目小结:
如果你能耐下心来,看完这三篇实战博文,相信你也可以做一个简单的app了。这个app实现并不难,博文讲解的也算是详尽,很容易理解。
这系列的博文,主要是针对初中级开发者,帮大家在研发过程中,理清思路,一步步完成一个完整的app。希望看完这篇博文的朋友,也能够举一反三, 做出一个自己所属的app。
