最近開(kāi)發(fā)的時(shí)候遇到這么一個(gè)崩潰弊添，找了半天原因終于找到問(wèn)題的原因债鸡。

主要的問(wèn)題是這個(gè)
Caused by: java.lang.UnsupportedOperationException: Failed to resolve attribute at index 13: TypedValue{t=0x2/d=0x7f0302a9 a=2}
這個(gè)錯(cuò)誤是TypedArray代碼拋出的
frameworks/base/core/java/android/content/res/TypedArray.java
public ColorStateList getColorStateList(int index) {
if (mRecycled) {
throw new RuntimeException("Cannot make calls to a recycled instance!");
}
final TypedValue value = mValue;
if (getValueAt(index*AssetManager.STYLE_NUM_ENTRIES, value)) {
if (value.type == TypedValue.TYPE_ATTRIBUTE) {
throw new UnsupportedOperationException(
"Failed to resolve attribute at index " + index + ": " + value);
}
return mResources.loadColorStateList(value, value.resourceId, mTheme);
}
return null;
}
上邊的源碼可以看出是TypedValue.TYPE_ATTRIBUTE類型就會(huì)拋出這個(gè)exception
可以看出TypedValue{t=0x2/d=0x1010351 a=1}其中的t=0x2就是指類型為2，其它含義參見(jiàn)代碼
public String toString()
{
StringBuilder sb = new StringBuilder();
sb.append("TypedValue{t=0x").append(Integer.toHexString(type));
sb.append("/d=0x").append(Integer.toHexString(data));
if (type == TYPE_STRING) {
sb.append(" \"").append(string != null ? string : "<null>").append("\"");
}
if (assetCookie != 0) {
sb.append(" a=").append(assetCookie);
}
if (resourceId != 0) {
sb.append(" r=0x").append(Integer.toHexString(resourceId));
}
sb.append("}");
return sb.toString();
}
其中的"a="只對(duì)string有意義庸论，這個(gè)獲取的是color职辅，所以“a=1”沒(méi)啥含義
/** Additional information about where the value came from; only
* set for strings. */
public int assetCookie;
其中的d是資源id，framework中的資源id是預(yù)先指定好的聂示，app的編譯時(shí)動(dòng)態(tài)確定域携。
frameworks/base/core/res/res/values/public.xml
<public type="attr" name="background" id="0x7f0302a9" />
其中的0x7f0302a9就是指background，報(bào)錯(cuò)的原因就是background最終沒(méi)有確認(rèn)成一個(gè)確定的值鱼喉。
出現(xiàn)這個(gè)原因主要是因?yàn)橐昧薗mui的ui庫(kù)秀鞭，但是activity的theme沒(méi)有繼承QMUI.Compat.NoActionBar，所以導(dǎo)致設(shè)置背景的時(shí)候找不到對(duì)應(yīng)的資源出現(xiàn)的這個(gè)問(wèn)題扛禽。繞了很大一圈锋边，這里記錄一下問(wèn)題。
