矫情吗；* 2023-10-16 21:37 27阅读 0赞

本篇是ProgressWheel使用的第二篇(尾篇)，功能是在自定义标题栏中显示ProgressWheel滚动条。

###  ###

1.  本篇引用的开源项目依然是ProgressWheel,地址：

3.  自定义滚动条（在自定义标题栏中显示）的实现：
    
    #### 1）activity\_progress\_wheel\_test. xml： ####

#### 2） titlebar\_detail.xml： ####

<?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:ProgressWheel="http://schemas.android.com/apk/res-auto"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="horizontal"
        android:background="@color/blue" >
    
        <ImageView
            android:id="@+id/imageview_back"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerVertical="true"
            android:src="@drawable/ic_launcher" />
    
        <TextView
            android:id="@+id/textview_middle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:text="@string/home"
            android:textColor="@color/white"
            android:textSize="18sp" />
    
        <com.todddavies.components.progressbar.ProgressWheel
            android:id="@+id/progressBar"
            android:layout_width="46dp"
            android:layout_height="46dp"
            android:layout_alignParentRight="true"
            android:layout_centerVertical="true"
            ProgressWheel:barColor="#0097D6"
            ProgressWheel:barLength="30dp"
            ProgressWheel:barWidth="5dp"
            ProgressWheel:contourColor="#330097D6"
            ProgressWheel:rimColor="@color/white"
            ProgressWheel:rimWidth="5dp"
            ProgressWheel:spinSpeed="10dp"
            ProgressWheel:text="0/0"
            ProgressWheel:textColor="#FFFFFF"
            ProgressWheel:textSize="12sp"
            android:visibility="gone"
             />
    
        <ImageView
            android:id="@+id/imageView_Right"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:layout_centerVertical="true"
            android:layout_marginRight="5dp"
    
            android:src="@drawable/search_normal"
    
            />
    
    </RelativeLayout>

#### 3）自定义的styles：(在styles文件中)： ####

<style name="CustomWindowTitleBackground">
            <item name="android:background">@color/honeydew</item>
        </style>
    
        <style name="test" parent="android:Theme">
            <item name="android:windowTitleSize">48dp</item>
            <item name="android:windowTitleBackgroundStyle">@style/CustomWindowTitleBackground</item>
        </style>

#### 4）. java代码：ProgressWheelTestActivity.java ####

            MyHandler() {
            }
    
    
            public void start() {
                showProgressWheel();
                sendEmptyMessage(200);
            }
    
            @Override

                if (msg.what == 200) {
    
                    startTestThread();
                }else if (msg.what == 300) {

                    closeProgressWheel();
                }

                @Override
                public void run() {
    
                    try {
                        Thread.sleep(3000);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                    mMyHandler.loop++;
                    if (mMyHandler.loop<5) {
                        setProgressWheelText("" + mMyHandler.loop + "/" + 5);
                        mMyHandler.sendEmptyMessage(200);
                    }else {
                        //结束时，发送300
                        mMyHandler.sendEmptyMessage(300);
                    }
    
                }
    
            }).start();
    
        }
    }

#### 5）说明： ####

1. 需要导入ProgressWheel jar包或者以library的方式导入到项目中;
    2. 自定义titlebar的实现（注意加载完成后右边的图片会更新）;
    3. 请区别本博ProgressWheel 使用的第一篇的实现方式，第一篇用的是静态的方式实现的。

开源的力量是无穷的！
