The above error codes can be easily located and solved in Android Studio. There are two solutions:
- Find the activity that reported the error (the above error log is com.example.activitylifecycletest.DialogActivity) and modify the theme theme in AndroidManifest.xml to make it refer to theme.appcompat.***. ps: If it is invalid, you can modify the theme of Application, Also referenced in the.appcompat.
- Modify the inheritance relationship of DialogActivity so that it does not inherit AppCompatActivity, just inherit Activity
If you encounter this problem when decompiling, then things are different. When I encountered this problem for the first time, I found that there was no problem with the inheritance relationship of Activity and the theme index of theme. So what is the problem?
After pondering for a long time, I found this code in the AppCompatDelegateImpl class:
if (!a.hasValue(R.styleable.AppCompatTheme_windowActionBar)) {
a. recycle();
throw new IllegalStateException(
"You need to use a Theme.AppCompat theme (or descendant) with this activity.");
}
R.styleable.AppCompatTheme_windowActionBar
This resource index doesn’t seem to be found. After searching, I found that I couldn’t find it. I copied all the resource files generated by decompilation, and the resource of declare-styleable.xml required by R.styleable.AppCompatTheme_windowActionBar was converted into The attr tag in attrs.xml.
For example: AppCompatTheme’s styleable is defined as:
<declare-styleable name="AppCompatTheme">

</declare-styleable>
But what I got was the decompiled resource identifier, the declare-styleable tag was removed, the name attribute could not be found, only attr, then R.styleable.AppCompatTheme_windowActionBar must not be found, so an error was reported. .
Solution
It is to get declare-styleables.xml again, delete attr defined in declare-styleables.xml in attrs, and the problem is solved~
