前言
也是突发奇想想做一个仿一言app一样的可以显示不同的格言的app，不过可惜这个项目也是
只做了一半，但是基本的功能还是实现了一半一半了，本来说弄完的但是好像时间总是限制了我的
idea，害下次一定更新完
项目框架构
项目框架下黄色标注的是主代码模块，因为这是我自己的测试程序所以里面有一些当时用过的冗余代码
不用理会的，打叉的是都不用的。至于代码其实也没什么好说的，也没有什么，就是三个format的转换罢了
其实，还是有一些BUG的在第三个页面的format我还没有弄好，目前只是暂时实现了随机显示图片和文字，但是
随机显示图片因为api的特性，显示图片总是容易重复这就很烦了，刷新的问题还是很难解决总是让人很难受的。
主活动
其实无外乎就是在format里调用api然后显示把获取的数据放到控件里我也懒得解释了直接看代码就行了
主活动main1.java

oneformat
第一个页面的format其实你看框架图的时候应该看见了在one这个文件件下是有两个文件的
GalleryTransformer这个是用来设置透明度和缩放效果的，没什么好说的网上一大堆一看就懂。
oneformat.java
public class oneFragment extends Fragment {
private ViewPager mViewCard;
private ImageView image1;
public static Bitmap alubm;
public static Drawable drawable1;
public static Drawable drawable2;
private ViewPager mVpCard;
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_main, container, false);
mViewCard = (ViewPager) view.findViewById(R.id.vp_card);
mViewCard.setAdapter(new ViewPagerCardAdapter());
mViewCard.setOffscreenPageLimit(2);//预加载2个
mViewCard.setPageMargin(50);//设置viewpage之间的间距
mViewCard.setClipChildren(false);
mViewCard.setPageTransformer(true, new GalleryTransformer());
ViewPagerCardAdapter viewPagerCardAdapter = new ViewPagerCardAdapter();
drawable1 = getResources().getDrawable(R.drawable.chatchose);
drawable1.setBounds(0, 0, 40, 40);//第一0是距左右边距离，第二0是距上下边距离，第三长度,第四宽度
drawable2 = getResources().getDrawable(R.drawable.heart);
drawable2.setBounds(0, 0, 40, 40);//第一0是距左右边距离，第二0是距上下边距离，第三长度,第四宽度
//initViews(view);
return view;
}
}
其实看这个布局你和实现是不一样的因为我用了画廊工具把他缩小了所以可以看的样子是那种悬浮可以滑动的
就是下面的onemain这个布局文件 ,吧oneformat里面的布局放在onemain里就可以让你的布局像我一样了！

实在是没办法了，只能先这样等等闲了在看，其实如果写个json是可以显示的，满足我的要求，但是实话
是我没有这么多图片和内存，只能用api了，但是没办啊api的这种特性它刷新就是有点延迟，网速块的时候
就没有这种问题了

适配器
这有两个适配器没有写完，这个是暂时版本等我更新！一个是圆形头像的适配器
threeAdapter.java
package com.example.httpclinedemo.PageAdapter;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.RelativeLayout;
import android.widget.TextView;
import com.example.httpclinedemo.R;
import java.util.List;
public class threeAdapter extends BaseAdapter {
private Context context;
private List<Integer> list;
LayoutInflater layoutInflater;
private ImageView imageView;
public threeAdapter(Context context,List<Integer> list){
this.context = context;
this.list = list;
layoutInflater = LayoutInflater.from(context);
}
public int getCount(){
return list.size()+1;//注意此处
}
public Object getItem(int position) {
return list.get(position);
}
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
convertView = layoutInflater.inflate(R.layout.item_img, null);
imageView = (ImageView) convertView.findViewById(R.id.iv_thum);
if (position < list.size()) {
imageView.setBackgroundResource(list.get(position));
}else{
imageView.setBackgroundResource(R.mipmap.add_icon);//最后一个显示加号图片
}
return convertView;
}
}
```
## RoundImageView.java
```java
public class RoundImageView extends androidx.appcompat.widget.AppCompatImageView {
public RoundImageView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public RoundImageView(Context context) {
super(context);
init();
}
private final RectF roundRect = new RectF();
private float rect_adius = 90;
private final Paint maskPaint = new Paint();
private final Paint zonePaint = new Paint();
private void init() {
maskPaint.setAntiAlias(true);
maskPaint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
maskPaint.setFilterBitmap(true);
zonePaint.setAntiAlias(true);
zonePaint.setColor(Color.WHITE);
zonePaint.setFilterBitmap(true);
float density = getResources().getDisplayMetrics().density;
rect_adius = rect_adius * density;
}
public void setRectAdius(float adius) {
rect_adius = adius;
invalidate();
}
@Override
protected void onLayout(boolean changed, int left, int top, int right,
int bottom) {
super.onLayout(changed, left, top, right, bottom);
int w = getWidth();
int h = getHeight();
roundRect.set(0, 0, w, h);
}
@Override
public void draw(Canvas canvas) {
canvas.saveLayer(roundRect, zonePaint, Canvas.ALL_SAVE_FLAG);
canvas.drawRoundRect(roundRect, rect_adius, rect_adius, zonePaint);
//
canvas.saveLayer(roundRect, maskPaint, Canvas.ALL_SAVE_FLAG);
super.draw(canvas);
canvas.restore();
}
}
总结
我跟周杰伦有的一比，除啦才艺比不上，玩是比他还爱玩.......
我很可爱，请我喝冰可乐
