如上图所示,总共5个framgent及其对应的5个布局文件,下面给出示例代码,复杂漂亮的界面待你实现。
2.Fav_Fragment.java
1 package com.example.framgent; 2 3 4 import com.example.tab1.R; 5 6 import android.os.Bundle; 7 import android.support.v4.app.Fragment; 8 import android.view.LayoutInflater; 9 import android.view.View; 10 import android.view.ViewGroup; 11 import android.widget.TextView; 12 13 public class Fav_Fragment extends Fragment{ 14 15 @Override 16 public void onCreate(Bundle savedInstanceState) { 17 // TODO Auto-generated method stub 18 super.onCreate(savedInstanceState); 19 } 20 21 @Override 22 public View onCreateView(LayoutInflater inflater, ViewGroup container, 23 Bundle savedInstanceState) { 24 View view = inflater.inflate(R.layout.fav, container, false); 25 return view; 26 } 27 28 }
3.fav.xml
1 <?xml version="1.0" encoding="utf-8"?> 2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 3 android:layout_width="match_parent" 4 android:layout_height="match_parent" 5 android:background="@android:color/white" 6 android:orientation="vertical"> 7 <TextView 8 android:layout_width="wrap_content" 9 android:layout_height="wrap_content" 10 android:padding="8dp" 11 android:text="酒店收藏" 12 android:textColor="#000" 13 android:textSize="17sp" /> 14 15 16 </LinearLayout>
还有一些细节美化部分,具体的请看代码吧。
