代碼設置progressbar的progressdrawable方法

項目里面有個地方的progressbar總是報圖片oom,很奇葩.

最初的progressdrawable的xml文件如下

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@android:id/background"
        android:drawable="@drawable/progress_default_background" />
    <item android:id="@android:id/progress" >
        <clip>
            <nine-patch android:src="@drawable/progress_default"/>
        </clip>
    </item>
</layer-list>

先是把.9圖改為顏色

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@android:id/background"
        android:drawable="@drawable/progress_bg" />
    <item android:id="@android:id/progress"
        android:drawable="@drawable/progress_hl" />
</layer-list>

<!-- 背景-->
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#E0E0E0"></solid>
    <corners android:radius="1dip"></corners>
</shape>

<!-- 進度-->
<clip xmlns:android="http://schemas.android.com/apk/res/android">
    <shape>
        <solid android:color="#70B23F"></solid>
        <corners android:radius="1dip"></corners>
    </shape>
</clip>

然並卵,還是報oom.

於是想在代碼里用progressbar.setprogressdrawable()來設置,可是如果是從xml中獲得的progressdrawable,發現進度是不會動的.

在網上看了好多人回答,大部分還是xml設置,貌似沒什么人用代碼設置progressdrawable.

自己試了好久終於設置成功了.代碼如下

　　　　 GradientDrawable p=new GradientDrawable();
        p.setCornerRadius(dipToPixels(mContext, 1));
        p.setColor(Color.rgb(0x70, 0xb2, 0x3f));
        ClipDrawable progress = new ClipDrawable(p, Gravity.LEFT, ClipDrawable.HORIZONTAL);
        GradientDrawable background = new GradientDrawable();
        background.setColor(Color.rgb(0xe0, 0xe0, 0xe0));
        background.setCornerRadius(dipToPixels(mContext,1));
        LayerDrawable pd=new LayerDrawable(new Drawable[]{background,progress});
　　　　　progressbar.setProgressDrawable(pd)

效果看起來沒問題了,希望測試不要又測出什么bug
