2017.1.16 进度 项目4开头

Posted 2020-08-28

今天的大部分时间都用在想UI怎么设计以及，如何把button放在title bar上，结果后者怎么也实现不了，于是只好先放弃在这次的这个音乐播放半成品里面使用了。

其实想想也是，这次的主要考察对象是activity之间的转换，我总是把它的重点跑偏……

放上代码存个档:

activity_main.xml

 1 <?xml version="1.0" encoding="utf-8"?>
 2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 3     xmlns:tools="http://schemas.android.com/tools"
 4     android:id="@+id/activity_main"
 5     android:layout_width="match_parent"
 6     android:layout_height="match_parent"
 7     android:orientation="vertical"
 8     android:background="@color/whole"
 9     tools:context="com.example.android.ourmusic.MainActivity">
10 
11     <TextView
12         android:id="@+id/play_now"
13         style="@style/text"
14         android:layout_width="match_parent"
15         android:background="@color/play_now"
16         android:text="@string/play_now"
17         android:textSize="24sp" />
18 
19     <ScrollView
20         android:layout_width="match_parent"
21         android:layout_height="wrap_content">
22 
23         <TextView
24             android:id = "@+id/local_music"
25             style="@style/text"
26             android:text="@string/local_music" />
27     </ScrollView>
28 </LinearLayout>

color.xml

1 <?xml version="1.0" encoding="utf-8"?>
2 <resources>
3     <color name="colorPrimary">#696969</color>
4     <color name="colorPrimaryDark">#696969</color>
5     <color name="colorAccent">#FF4081</color>
6     <color name="play_now">#DCDCDC</color>
7     <color name="whole">#F5F5F5</color>
8 </resources>

style.xml

 1 <resources>
 2 
 3     <!-- Base application theme. -->
 4     <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
 5         <!-- Customize your theme here. -->
 6         <item name="colorPrimary">@color/colorPrimary</item>
 7         <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
 8         <item name="colorAccent">@color/colorAccent</item>
 9     </style>
10 
11     <!--For most of TextView-->
12     <style name="text">
13         <item name="android:layout_width">match_parent</item>
14         <item name="android:layout_height">wrap_content</item>
15         <item name="android:textSize">24sp</item>
16         <item name="android:layout_margin">8dp</item>
17         <item name="android:gravity">center_horizontal</item>

19         <item name="android:textColor">@android:color/black</item>
20         <item name="android:background">@color/play_now</item>
21         <item name="android:padding">16dp</item>
22 
23     </style>
24 
25 </resources>

string.xml

<resources>
    <string name="app_name">Our Music</string>
    <string name="action_play">play</string>
    <string name="local_music">本地音乐</string>
    <string name="download_manage">下载管理</string>
    <string name="rencent_play">最近播放</string>
    <string name="my_music_list">我的歌单</string>
    <string name="default_music_list">默认歌单</string>
    <string name="creat_new_music_list">创建新的歌单</string>
    <string name="play_now">正在播放</string>
</resources>

还有个不会用的menu.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <menu xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app = "http://schemas.android.com/apk/res-auto">

        <!-- "Mark Favorite", should appear as action button if possible -->
        <item
            android:id="@+id/action_play"
            android:icon="@drawable/music"
            android:title="@string/play"
            app:showAsAction="ifRoom"/>

    </menu>
</resources>

 

MainActivity.java

 1 package com.example.android.ourmusic;
 2 
 3 import android.graphics.Typeface;
 4 import android.os.Bundle;
 5 import android.support.v7.app.AppCompatActivity;
 6 import android.widget.TextView;
 7 
 8 public class MainActivity extends AppCompatActivity {
 9 
10     @Override
11     protected void onCreate(Bundle savedInstanceState) {
12         super.onCreate(savedInstanceState);
13         setContentView(R.layout.activity_main);
14         String customFont = "汉仪南宫体简.ttf";
15         Typeface typeface = Typeface.createFromAsset(getAssets(), customFont);
16         TextView textView = (TextView) findViewById(R.id.play_now);
17         TextView textView1 = (TextView)findViewById(R.id.local_music);
18         textView.setTypeface(typeface);
19         textView1.setTypeface(typeface);
20     }
21 
22 }

 

哎每次一总结就发现自己写的东西特别少……还花了两个多小时？好废哦……
