Question

如果我在SeekBar中设置了draw“progress drawable”，我会在所有进度行中获得bgdraw。如何从开始到拇指位置设置绘图？

Answer 1

你可以这样使用：

在可绘制文件夹中制作自定义文件....

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

<item android:id="@android:id/background" >

    <shape>
        <gradient 
                android:startColor="#00000000"
                android:centerColor="#00000000"
                android:centerX="1"
                android:endColor="#00000000"
                android:angle="0"
        />
    </shape>
</item>
<item android:id="@android:id/secondaryProgress" >
    <clip android:clipOrientation="horizontal" android:gravity="left" >
        <shape>
            <gradient
                    android:startColor="@color/blue"
                    android:centerColor="@color/blue"
                    android:centerX="0.75"
                    android:endColor="@color/blue"
                    android:angle="0"
            />
        </shape>
    </clip>
</item>

<item android:id="@android:id/progress" >
    <clip android:clipOrientation="horizontal" android:gravity="left" >
        <shape>
            <gradient
                    android:startColor="@color/blue"
                    android:centerColor="@color/blue"
                    android:centerX="0.75"
                    android:endColor="@color/blue"
                    android:angle="0"
            />
        </shape>
    </clip>
</item>

然后在xml文件中设置此自定义文件：

  <SeekBar
            android:id="@+id/skProgress"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginLeft="10dp"
            android:layout_marginRight="10dp"
            android:layout_marginTop="10dp"
            android:background="@android:color/white"
            android:gravity="center|center_vertical"
            android:progressDrawable="@drawable/progress_Ever" // here whatever name your custom file in drawable...set to here
  />

在您的xml中

<SeekBar
                android:id="@+id/skProgress"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginLeft="10dp"
                android:layout_marginRight="10dp"
                android:layout_marginTop="10dp"
                android:background="@android:color/white"
                android:gravity="center|center_vertical"
                android:progressDrawable="@drawable/progress_drawable"
 />

progress_drawable.xml

将此xml放入Drawable文件夹

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:id="@android:id/background" >

        <shape>
            <gradient 
                    android:startColor="#00000000"
                    android:centerColor="#00000000"
                    android:centerX="1"
                    android:endColor="#00000000"
                    android:angle="0"
            />
        </shape>
    </item>
    <item android:id="@android:id/secondaryProgress" >
        <clip android:clipOrientation="horizontal" android:gravity="left" >
            <shape>
                <gradient
                        android:startColor="@color/blue"
                        android:centerColor="@color/blue"
                        android:centerX="0.75"
                        android:endColor="@color/blue"
                        android:angle="0"
                />
            </shape>
        </clip>
    </item>

    <item android:id="@android:id/progress" >
        <clip android:clipOrientation="horizontal" android:gravity="left" >
            <shape>
                <gradient
                        android:startColor="@color/blue"
                        android:centerColor="@color/blue"
                        android:centerX="0.75"
                        android:endColor="@color/blue"
                        android:angle="0"
                />
            </shape>
        </clip>
    </item>

</layer-list>

Answer 3

在你的xml中放这个

<SeekBar  
        .....               
        android:background="@null"
        android:splitTrack="false"
        android:progressDrawable="@drawable/progress_drawable"
 />

并在您的seek_bar_progress drawable中留空背景部分，但将渐变部分放入剪辑标记。

<item android:id="@android:id/secondaryProgress" >
    <clip android:clipOrientation="horizontal" android:gravity="left" >
        <shape>
            <gradient
                    android:startColor="@color/blue"
                    android:centerColor="@color/blue"
                    android:centerX="0.75"
                    android:endColor="@color/blue"
                    android:angle="0"
            />
        </shape>
    </clip>
</item>
