自定义流式布局：之前的一篇文章写过，这里就不阐述了：http://blog.csdn.net/_/article/details/

随后封装一个方法工具类：GradientDrawable代替shape,StateListDrawable替换selector设置

public class DrawUtils { //GradientDrawable代替shape  public static Drawable getDrawable(int rgb, float radius) { GradientDrawable gradientDrawable = new GradientDrawable();  gradientDrawable.setColor(rgb);//设置颜色  gradientDrawable.setGradientType(GradientDrawable.RECTANGLE);//shape矩形  gradientDrawable.setCornerRadius(radius);//设置圆角半径  gradientDrawable.setStroke(UIUtils.dp2px(1), rgb);//设置边框厚度和颜色  return gradientDrawable;  } //StateListDrawable替换selector设置  public static StateListDrawable getSelector(Drawable normalDrawable, Drawable pressDrawable) { StateListDrawable stateListDrawable = new StateListDrawable();  //给当前的颜色选择器添加选中图片指向状态，未选中图片指向状态  stateListDrawable.addState(new int[]{android.R.attr.state_enabled, android.R.attr.state_pressed}, pressDrawable);  stateListDrawable.addState(new int[]{android.R.attr.state_enabled}, normalDrawable);  //设置默认状态  stateListDrawable.addState(new int[]{}, normalDrawable);  return stateListDrawable;  } }

首先写一个文字集合

private String[] datas = new String[]{ 
 "北京欢迎你", "迪士尼3天旅游", "国家计划", "30天理财计划", "180天理财计划", "月月涨工资", "中商情报局投资牛逼", "大学老师购买房子", "屌丝下海经商计划", "美人鱼影视拍摄投资"  , "Android冷门", "养猪场扩大经营",  "旅游公司诈骗计划", "手机洗钱计划", "妲己回款计划", "高富帅迎娶白富美计划" };

new一个TextView设置参数并添加到自定义的FlowLayout布局中

 for (int i = 0; i < datas.length; i++) { final TextView tv = new TextView(getContext());  tv.setText(datas[i]);  ViewGroup.MarginLayoutParams mp = new ViewGroup.MarginLayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,  ViewGroup.LayoutParams.WRAP_CONTENT);  mp.leftMargin = UIUtils.dp2px(5);  mp.rightMargin = UIUtils.dp2px(5);  mp.topMargin = UIUtils.dp2px(5);  mp.bottomMargin = UIUtils.dp2px(5);  tv.setLayoutParams(mp);  int padding = UIUtils.dp2px(5);  tv.setPadding(padding, padding, padding, padding);//设置内边距  tv.setTextSize(UIUtils.dp2px(10));  Random random = new Random();  int red = random.nextInt(211);  int green = random.nextInt(211);  int blue = random.nextInt(211);  //设置单一背景  //tv.setBackground(DrawUtils.getDrawable(Color.rgb(red,green,blue),UIUtils.dp2px(5)));  tv.setBackground(DrawUtils.getSelector(DrawUtils.getDrawable(Color.rgb(red, green, blue), UIUtils.dp2px(5)) , DrawUtils.getDrawable(Color.WHITE, UIUtils.dp2px(5))));  //设置textView是可点击的.如果设置了点击事件，则TextView就是可点击的。 // tv.setClickable(true);  tv.setOnClickListener(new View.OnClickListener() { @Override  public void onClick(View v) { Toast.makeText(getContext(), tv.getText().toString(), Toast.LENGTH_LONG).show();  } });  flowHot.addView(tv);  }
