寫了一個很簡單的佈局
這是周圍圓框的drawable

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <stroke
        android:width="1dp"
        android:color="#ff666f" />

    <corners android:radius="15dp" />
</shape>

xml的佈局

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#B1F4CD"
    tools:context=".MainActivity">


    <com.bwie.administrator.rikao1130.floatview.MyFloatLayout
        android:id="@+id/My"
        android:layout_width="match_parent"
        android:layout_height="match_parent"></com.bwie.administrator.rikao1130.floatview.MyFloatLayout>

</RelativeLayout>
 

自定義View的程式碼

package com.bwie.administrator.rikao1130.floatview;


import android.content.Context;
import android.graphics.Color;
import android.util.AttributeSet;
import android.util.DisplayMetrics;
import android.view.View;
import android.view.ViewGroup;
import android.widget.LinearLayout;
import android.widget.TextView;
import com.bwie.administrator.rikao1130.R;
public class MyFloatLayout extends LinearLayout {
    private final int widthPixels;
    public MyFloatLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
        DisplayMetrics metrics = context.getResources().getDisplayMetrics();
        widthPixels = metrics.widthPixels;
        //設定佈局垂直顯示
        setOrientation(VERTICAL);
    }
    public void setData(String[] data) {
        LinearLayout linearLayout = getLin();
        for (int i = 0; i < data.length; i++) {
            String tmp = data[i];
            int numWidth = 0;
            //得到一行LinearLayout到底有多少子控制元件  因為我要計算每個子控制元件加在一起的寬度
            int childCount = linearLayout.getChildCount();
            //這個for迴圈只是計算一行LinearLayout的所有子控制元件的寬的和
            for (int j = 0; j < childCount; j++) {
                //通過index得到每一個子控制元件
                TextView tv = (TextView) linearLayout.getChildAt(j);
                LayoutParams layoutParams = (LayoutParams) tv.getLayoutParams();
                int leftMargin = layoutParams.leftMargin;
                //測量這個tv的寬和高
                tv.measure(getMeasuredWidth(), getMeasuredHeight());
                numWidth += tv.getMeasuredWidth() + leftMargin + tv.getPaddingLeft() + getPaddingRight();
            }
            TextView dataText = getText();
            //設定文字屬性
            LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
            params.leftMargin = 20;
            params.topMargin = 2;
            dataText.setLayoutParams(params);
            dataText.setText(tmp);
            dataText.measure(getMeasuredWidth(), getMeasuredHeight());
            //計算寬
            int dataTextWidth = dataText.getMeasuredWidth() + dataText.getPaddingLeft() + dataText.getPaddingRight();
            //考慮到字串可能會很長,超過螢幕的寬度,此處進行一個判斷
            if (dataTextWidth >= widthPixels) {
                String substring = tmp.substring(0, 6);
                dataText.setText(substring + "...");
                //重新計算字串的寬度
                dataText.measure(getMeasuredWidth(), getMeasuredHeight());
                dataTextWidth = dataText.getMeasuredWidth();
            }
            if (widthPixels >= numWidth + dataTextWidth) {
                linearLayout.addView(dataText);
            } else {
                //對LinearLayout重新賦值,通過getLin換行
                linearLayout = getLin();
                linearLayout.addView(dataText);
            }
        }
    }
    private TextView getText() {
        TextView textView = new TextView(getContext());
        textView.setTextSize(24);
        textView.setTextColor(Color.RED);
        textView.setBackgroundResource(R.drawable.text_style);
        textView.setPadding(10, 20, 10, 20);
        return textView;
    }
    private LinearLayout getLin() {
        LinearLayout linearLayout = new LinearLayout(getContext());
        //LayoutParams 控制組件大小的一個工具類
        LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
        linearLayout.setLayoutParams(params);
        //this本類物件
        this.addView(linearLayout);//只要重新新增view了自動換行了
        return linearLayout;
    }
}
 

mineActivity的程式碼

package com.bwie.administrator.rikao1130;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

import com.bwie.administrator.rikao1130.floatview.MyFloatLayout;

public class MainActivity extends AppCompatActivity {
    private String[] data = {"BigFly最帥", "最帥的是BigFly","BigFly帥", "最帥BigFly","BigFly最帥", "最帥的是BigFly","BigFly最帥", "最帥的是BigFly", "BigFly怎麼那麼帥,特別特別特別特別特別特別特別帥"};
    private MyFloatLayout My;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initView();

    }

    private void initView() {
        My = (MyFloatLayout) findViewById(R.id.My);
        My.setData(data);
    }
}
