• 第一次发布

使用前:

   public TFragment newInstance(String username, String password, int age) {
        TFragment tFragment = new TFragment();
//传值
        Bundle bundle = new Bundle();
        bundle.putString("username", username);
        bundle.putString("password", password);
        bundle.putInt("age", age);
        tFragment.setArguments(bundle);
        return tFragment;
    }
    
    @Override
    public void onAttach(Context context) {
        super.onAttach(context);
        //使用
        Bundle arguments = getArguments();
        mUsername = arguments.getString("username");
        mPassword = arguments.getString("password");
        age = arguments.getInt("age");
    }

使用后:

    //定义
    @Inject
    public String mUsername;
    @Inject(name = "password1")
    public String mPassword;
    @Inject
    public int age;
    //传值
     TFragment2 tFragment = new TFragment2Key().send("姓名", "密码", 10);
      
    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        //使用
        Log.d(TAG, mUsername);
        Log.d(TAG, mPassword);
        Log.d(TAG, String.valueOf(age));
        return super.onCreateView(inflater, container, savedInstanceState);
    }

可以看出此框架简化了传值过程,避免了使用key来传递数据带来的麻烦.

Installation：

1.project.gradle

    buildscript {
    repositories {
        google()
        jcenter()
        maven { url 'https://jitpack.io' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
    }
}

2.app.gradle 添加

dependencies {
   implementation 'com.github.TanZhiL.FragmentKey:fragmentkey:1.0.2'
    annotationProcessor 'com.github.TanZhiL.FragmentKey:fragmentkey-compiler:1.0.2'
}

Usage：

1.在需要外部传递的字段上加上Inject注解,然后build

   @Inject
    public String mUsername;
    //name为自定义key值,默认为字段名
    @Inject(name = "password1")
    public String mPassword;
    @Inject
    public int age;

2.创建fragment实例时使用xxxKey.send(...)方法;xxxKey类由apt自动生成.

      TFragment2 tFragment = new TFragment2Key().send("姓名", "密码", 10);

注意:

目前以支持bundle能传递的常见类型字段

   @Inject
    protected String s;
    @Inject
    protected Integer i;
    @Inject
    protected boolean b;
    @Inject
    protected float f;
    @Inject
    protected double d;
    @Inject
    protected long l;
    @Inject
    protected ArrayList<String> ls;
    @Inject
    protected ArrayList<Integer> li;
    @Inject
    protected ArrayList<Parcelable> lp;
    @Inject
    protected Serializable se;
    @Inject
    protected Parcelable p;
