res/xml/prefs.xml 文件:
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<com.estysoft.android.preference.SeekBarPreference
android:dialogMessage="Something duration"
android:key="duration"
android:summary="How long something will last"
android:text=" minutes"
android:min="5"
android:defaultValue="5"
android:max="60"
android:title="Duration of something"/>
</PreferenceScreen>
我的问题是 android:min="5"给出了 error: No resource identifier found for attribute 'min' in package 'android'. 如何为我的自定义设置最小值SeekBarPreference?
编辑，我将 SeekBarPreference 源添加到

}

mValueText.setText(mSuffix == null ? t : t.concat(mSuffix));
if (shouldPersist())
persistInt(value);
callChangeListener(new Integer(value));
}
public void onStartTrackingTouch(SeekBar seek) {
}

}
public void setMax(int max) {
mMax = max;
}

}

}

}
}
