先把布局写好 然后建一个 自定义控件
名字随便起。

在自定义 控件 里 继承一个 viewgroup
重写它的三个方法

public class Liushi extends ViewGroup {
public Liushi(Context context) {
super(context);
}

public Liushi(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public Liushi(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
}

再写一个onMeasure测量

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    measureChildren(widthMeasureSpec , heightMeasureSpec);
}

再写个onLayout布局

@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {

    int width = getWidth();
    int row = 0;
    int diswidth = 18;

    for (int o = 0; o < getChildCount(); o++){
    
        View view = getChildAt(o);
        
        int measuredHeight = view.getMeasuredHeight();
        int measuredWidth = view.getMeasuredWidth();
        
        if (diswidth + measuredHeight > width){
            row ++ ;
            diswidth = 18;
        }
        
        view.layout(diswidth,row * measuredHeight , measuredWidth + diswidth , measuredHeight * (row+1));
        diswidth += measuredWidth;
        
    }
}

写完之后再在activity页面写
先在上面定义个 TextView 控件

下面是把搜索框的内容放上流失布局

    btn_find.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
           textView = new TextView(getActivity());
            String s = editText.getText().toString().trim();
            textView.setText(s+"  ");
            ViewGroup.MarginLayoutParams marginLayoutParams = new ViewGroup.MarginLayoutParams(ViewGroup.MarginLayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT);
            liushi.addView(textView,marginLayoutParams);
        }
    });
