Özel durumunu belirlemek için/ProgressDialog Drawable

Okuma sınırlı belgeleri Google'ın yapmış olması, hissettiğimi, onu değiştirmek mümkündür (drawable) durumunu belirlemek/ProgressDialog tarafından sadece oluşturma Yeni bir stil atamak için stil mülkiyet durumunu belirlemek. Ama bu düzgün çalışması için. Şimdiye kadar yaptığım şey burada:

Böyle bir şekil (mp2.xml) ben yarattım

<?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>

sonra bir animasyon (mp3.xml bu gibi yarattı

<?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>

sonra bir stil (attrs.xml bu gibi yarattı

<?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>

ve benim main.xml bu gibi stili var:

<?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>

Ama yine de daha önce olduğu gibi aynı drawable gösterir. Neyi yanlış yapıyorum?

Aşağıdaki özel bir ilerleme çubuğu oluşturmak için kullanıyorum.

Dosya res/drawable/progress_bar_states.xml farklı devletlerin renkler beyan eder:

<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>

Düzeni içinde kod xml:

<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>

Tadını çıkarın!
