请问有人已经遇到过这个问题吗？请帮我找出解决方案.提前致谢.

Answer 1

在你的stacktrace日志中你可以看到NoSuchMethodError - 这意味着系统无法找到以下方法:android.app.ActionBar.setHomeAsUpIndicator

如文档中所述:http: //developer.android.com/reference/android/app/ActionBar.html#setHomeAsUpIndicator(android.graphics.drawable.Drawable)

不知道你想要使用哪一个,但两者都是:

setHomeAsUpIndicator(Drawable)

和

setHomeAsUpIndicator(int)

在API级别18中添加.这意味着它们不适用于较低的API版本.这可能是您遇到问题的原因 - 您尝试在API版本较低的手机上执行此代码(低于JELLY_BEAN_MR2).

你有2个选择:

我.在调用此方法之前检查API版本:

if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.JELLY_BEAN_MR2) {
    actionBar.setHomeAsUpIndicator(int);
}

这样可以避免崩溃,但不会对较低的API版本产生任何影响 - 因此您可能希望使用第二个选项来实现样式目标.

二.而不是尝试从代码中设置homeAsUpIndicator - 您可以通过添加"android:homeAsUpIndicator"属性从样式安全地(因为它可以从API 11获得). http://developer.android.com/reference/android/R.attr.html#homeAsUpIndicator

<style name="AppTheme" parent="@android:style/Theme.Holo.Light">
    <item name="android:homeAsUpIndicator">@drawable/my_home_as_up_indocator</item>
</style>

问候.
