博客展示了两段代码，一是NetUtil类，用于网络请求，包含OkHttpClient的初始化和doGet方法；二是CustomView类，继承自FrameLayout，实现流式布局，处理子控件的布局和点击事件，还定义了点击监听器接口。

package comp.example.lenovo.qqqq.net;

import okhttp3.Call;
import okhttp3.OkHttpClient;
import okhttp3.Request;

/**

*/
public class NetUtil {

OkHttpClient okHttpClient ;

public static NetUtil netUtil = new NetUtil();

public NetUtil() {
okHttpClient = new OkHttpClient();
}

public static NetUtil getObject(){
return netUtil;
}

public String doGet(String url){

 Request build = new Request.Builder().url(url).get().build();

 Call call = okHttpClient.newCall(build);

 try{
     String string = call.execute().body().string();
     return string;
 }catch (Exception e){
     e.printStackTrace();
 }

 return null;

}
}

package comp.example.lenovo.demomonth;

import android.content.Context;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.util.AttributeSet;
import android.view.View;
import android.widget.FrameLayout;
import android.widget.TextView;

/**

public class CustomView extends FrameLayout {
private int space = 20;

public CustomView(@NonNull Context context) {
this(context,null);
}

public CustomView(@NonNull Context context, @Nullable AttributeSet attrs) {
this(context, attrs,0);
}

public CustomView(@NonNull Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);

}

@Override
protected void onLayout(boolean changed, int left, int top, int right, int bottom) {
super.onLayout(changed, left, top, right, bottom);
//先获取控件的宽度
int width = getWidth();
int hWidth = 0;
int rows = 0;
for (int i = 0; i < getChildCount(); i++) {
//获取每一个子控件
TextView textView = (TextView) getChildAt(i);
textView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
itmeClickLinstener.itemClick(textView);
}
});
//获取子控件的宽度和高度
int childWidth = textView.getWidth();
int childHeigth = textView.getHeight();
//累计宽度赋值类
hWidth = hWidth+(childWidth);
```
     if(hWidth>width){
         rows++;
         hWidth = childWidth;
     }
     //给子控件布局
     textView.layout(hWidth-childWidth,rows*childHeigth+(rows+1) ,hWidth,(rows + 1) * childHeigth + (rows + 1));
 }
```
}

public void setItmeClickLinstener(ItmeClickLinstener itmeClickLinstener) {
this.itmeClickLinstener = itmeClickLinstener;
}

private ItmeClickLinstener itmeClickLinstener;

public interface ItmeClickLinstener{
void itemClick(TextView view);
}
}
