ProgressBar/ProgressDialog的自定义Drawable

Question

阅读Google提供的有限文档后,我感觉可以通过简单地创建一个新样式并将其分配给ProgressBar的样式属性来更改ProgressBar/ProgressDialog的外观(可绘制).但我不能让它正常工作.这是我到目前为止所做的:

我创建了这样的形状(mp2.xml)

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
  android:shape="ring"
  android:innerRadiusRatio="4"
  android:thicknessRatio="4"
  android:useLevel="false">
 <size android:width="50dip" android:height="50dip" />
 <gradient android:type="sweep" android:useLevel="false" android:startColor="#300000ff" android:centerColor="#500000ff" android:endColor="#ff0000ff" />
</shape>

然后像这样创建了一个动画(mp3.xml):

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="false">
 <item android:duration="70">
  <rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="0" android:toDegrees="30" android:repeatCount="1" />
 </item>
 <item android:duration="70">
  <rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="30" android:toDegrees="60" android:repeatCount="1" />
 </item>
 <item android:duration="70">
  <rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="60" android:toDegrees="90" android:repeatCount="1" />
 </item>
 <item android:duration="70">
  <rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="90" android:toDegrees="120" android:repeatCount="1" />
 </item>
 <item android:duration="70">
  <rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="120" android:toDegrees="150" android:repeatCount="1" />
 </item>
 <item android:duration="70">
  <rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="150" android:toDegrees="180" android:repeatCount="1" />
 </item>
 <item android:duration="70">
  <rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="180" android:toDegrees="210" android:repeatCount="1" />
 </item>
 <item android:duration="70">
  <rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="210" android:toDegrees="240" android:repeatCount="1" />
 </item>
 <item android:duration="70">
  <rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="240" android:toDegrees="270" android:repeatCount="1" />
 </item>
 <item android:duration="70">
  <rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="270" android:toDegrees="300" android:repeatCount="1" />
 </item>
 <item android:duration="70">
  <rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="300" android:toDegrees="330" android:repeatCount="1" />
 </item>
 <item android:duration="70">
  <rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="330" android:toDegrees="360" android:repeatCount="1" />
 </item>
</animation-list>

然后创建了一个样式(attrs.xml),如下所示:

<?xml version="1.0" encoding="utf-8"?>
<resources>
 <style parent="@android:style/Widget.ProgressBar" name="customProgressBar">
  <item name="android:progressDrawable">@anim/mp3</item>
 </style>
</resources>

在我的main.xml中我设置了这样的样式:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
       android:orientation="vertical"
       android:layout_width="fill_parent"
       android:layout_height="fill_parent" android:drawingCacheQuality="high">
 <ProgressBar android:id="@+id/ProgressBar01"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content" style="@style/customProgressBar"/>
</LinearLayout>

但它仍然显示出与以前相同的可绘制性.我究竟做错了什么？

Answer 1

我使用以下内容创建自定义进度条.

File res/drawable/progress_bar_states.xml声明不同状态的颜色:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:id="@android:id/background">
        <shape>
            <gradient
                    android:startColor="#000001"
                    android:centerColor="#0b131e"
                    android:centerY="0.75"
                    android:endColor="#0d1522"
                    android:angle="270"
            />
        </shape>
    </item>

    <item android:id="@android:id/secondaryProgress">
        <clip>
            <shape>
                <gradient
                        android:startColor="#234"
                        android:centerColor="#234"
                        android:centerY="0.75"
                        android:endColor="#a24"
                        android:angle="270"
                />
            </shape>
        </clip>
    </item>

    <item android:id="@android:id/progress">
        <clip>
            <shape>
                <gradient
                    android:startColor="#144281"
                    android:centerColor="#0b1f3c"
                    android:centerY="0.75"
                    android:endColor="#06101d"
                    android:angle="270"
                />
            </shape>
        </clip>
    </item>

</layer-list>

和布局xml中的代码:

<ProgressBar android:id="@+id/progressBar"
    android:progressDrawable="@drawable/progress_bar_states"
    android:layout_width="fill_parent" android:layout_height="8dip" 
    style="?android:attr/progressBarStyleHorizontal" 
    android:indeterminateOnly="false" 
    android:max="100">
</ProgressBar>

请享用!

Answer 2

我在使用不确定进度对话框时遇到了一些麻烦,经过一些工作和反复试验我得到了它的工作.

首先,创建要用于"进度"对话框的动画.在我的情况下,我使用了5张图片.

../res/anim/progress_dialog_icon_drawable_animation.xml:

<animation-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/icon_progress_dialog_drawable_1" android:duration="150" />
    <item android:drawable="@drawable/icon_progress_dialog_drawable_2" android:duration="150" />
    <item android:drawable="@drawable/icon_progress_dialog_drawable_3" android:duration="150" />
    <item android:drawable="@drawable/icon_progress_dialog_drawable_4" android:duration="150" />
    <item android:drawable="@drawable/icon_progress_dialog_drawable_5" android:duration="150" />
</animation-list>

您想要显示ProgressDialog的位置:

dialog = new ProgressDialog(Context.this);
dialog.setIndeterminate(true);
dialog.setIndeterminateDrawable(getResources().getDrawable(R.anim.progress_dialog_icon_drawable_animation));
dialog.setMessage("Some Text");
dialog.show();

这个解决方案非常简单并且对我有用,你可以扩展ProgressDialog并使其在内部覆盖drawable,但是,这对于我需要的东西来说真的太复杂了所以我没有这样做.

Answer 3

尝试设置:

android:indeterminateDrawable="@drawable/progress" 

它对我有用.这里也是progress.xml的代码:

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:pivotX="50%" android:pivotY="50%" android:fromDegrees="0"
    android:toDegrees="360">

    <shape android:shape="ring" android:innerRadiusRatio="3"
        android:thicknessRatio="8" android:useLevel="false">

        <size android:width="48dip" android:height="48dip" />

        <gradient android:type="sweep" android:useLevel="false"
            android:startColor="#4c737373" android:centerColor="#4c737373"
            android:centerY="0.50" android:endColor="#ffffd300" />

    </shape>

</rotate> 

Answer 4

你的风格应该是这样的:

<style parent="@android:style/Widget.ProgressBar" name="customProgressBar">
    <item name="android:indeterminateDrawable">@anim/mp3</item>
</style>

Answer 5

定制进度与规模!

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:duration="150">
        <scale
            android:drawable="@drawable/face_no_smile_eyes_off"
            android:scaleGravity="center" />
    </item>
    <item android:duration="150">
        <scale
            android:drawable="@drawable/face_no_smile_eyes_on"
            android:scaleGravity="center" />
    </item>
    <item android:duration="150">
        <scale
            android:drawable="@drawable/face_smile_eyes_off"
            android:scaleGravity="center" />
    </item>
    <item android:duration="150">
        <scale
            android:drawable="@drawable/face_smile_eyes_on"
            android:scaleGravity="center" />
    </item>

</animation-list>

Answer 6

我做你的代码.我可以运行,但我需要修改两个地方:

1. name="android:indeterminateDrawable" 代替 android:progressDrawable

2. 修改名称attrs.xml ---> styles.xml
