冰镐坏了吗

Question

我用一个片段尝试了一些非常简单的测试。但是Icepick似乎并没有将String测试的值保存在outState捆绑包中。。。

public class MyFragment extends Fragment {
    @Icicle String test;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Icepick.restoreInstanceState(this,savedInstanceState);
    }
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View view = inflater.inflate(R.layout.fragment_settings, container, false);
        Log.d(TAG,"restored value of test="+test);
        return view;
    }
    @Override
    public void onSaveInstanceState(Bundle outState) {
        test="I have a value";
        super.onSaveInstanceState(outState);
        Icepick.saveInstanceState(this,outState);
        Log.d(TAG, "test="+test);
   }

我的等级结构如下：

apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'
android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"
    defaultConfig {
        applicationId "com.my31daychallenge.mysleepchallenge"
        minSdkVersion 15
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile 'com.android.support:design:22.2.0'
    compile 'com.jakewharton.threetenabp:threetenabp:1.0.1'
    apt 'com.bluelinelabs:logansquare-compiler:1.1.0'
    compile 'com.bluelinelabs:logansquare:1.1.0'
    compile 'com.jakewharton:butterknife:7.0.1'
    compile 'frankiesardo:icepick:3.0.0'
    provided 'frankiesardo:icepick-processor:3.0.0'
}

注意，我尝试了Icepick 3.0.2和3.0.3-SNAPSHOT的最新版本，但都不起作用，所以我想使用早期版本，得到相同的结果。

以及：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.2.3'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
allprojects {
    repositories {
        jcenter()
        maven {url "https://clojars.org/repo/"}
    }
}

我错过了什么？

Answer 1

在build.gradle文件中，对于此行provided 'frankiesardo:icepick-processor:3.0.0'，将provided更改为apt。这就行了。

Answer 2

好吧，我5分钟前就开始查看IcePick库了，所以如果这是一个愚蠢的答案，请记住：(

截至本承诺https://github.com/frankiesardo/icepick/commit/f60b4b9c0307be208178381661ee13b958eda531看起来应该使用@State而不是@Icicle。这能解决你的问题吗？

Answer 3

放入

Icepick.restoreInstanceState(this, savedInstanceState);

在onCreateView()中(而不是在onCreate中(
